Why It Matters

A custom manufacturing resource planning system that finally matches how your factory really works.

MRP for manufacturing often flops because of its one-size-fits-all approach — it’s just too rigid. Good production planning should reflect how your shop floor actually works, and update when things change. That’s why our approach is different. We build planning around your production type and connect it to MES, IoT, quality, and suppliers, so plans update continuously and reflect what’s actually happening on the floor.

Start with a controlled pilot.

Scale only when planning proves it can keep up with operations.

Modernizing unstable systems? Launching new products?

We build development environments that deliver enterprise-grade scalability, compliance-driven security, and control baked in from day one.

What We Offer

Services We Provide

  • Business Process Consulting

    We lead discovery with engineering, using real event logs and AI to produce execution-ready BPMN in days and deliver a feasibility-tested, costed, risk-adjusted roadmap with clear ROI and cutover planning.

    • Process reality audit. We extract the key processes from your production logs and turn them into a standardised process inventory that can be executed, and we also validate them against non-negotiable criteria you’ve agreed to beforehand.
    • Process Mining & Bottleneck Analysis. We use automated process-mining techniques on your event logs to build accurate models of how your processes work, and then we give you a list of high-priority changes that need to be made, along with a confidence score, and we validate all of this with test cases that you can track.
    • Predictive Ops Readiness Audit. Look at the quality of your data, who uses it, and how it’s been manipulated. We build a working prototype of a feature store for you, and we give you the green light on whether your systems are ready for model-driven ops — complete with drift detection and service level agreements.
    • Digital Twin Feasibility Sprint. We determine how much detail you’ll need from your sensors to make a digital twin work, and then we put together a hybrid physics+ML simulation contract that you can measure the success of with clear, measurable goals in just 6-8 weeks.
    • Execution Roadmap and ROI Model. Webuild out a step-by-step roadmap with clear stop/go checkpoints and a migration playbook, and we also produce an AI-driven ROI simulator so you can see the impact of your planned changes in a more realistic way.

    We end up with a plan signed off by everyone that cuts down on the time you spend on discovery, ties every recommendation to a real estimate of ROI, removes risk from your migration by giving you clear stop/go criteria, and translates everything we’ve found into a prioritised list of tasks with clear owners, service level agreements, and acceptance tests.

  • Custom MRP Core Development

    We’re building a 2025-era, cloud-first, microservices MRP for manufacturing that uses AI-driven planning, real-time plant and supplier signals, and continuous replanning.

    • BOM Intelligence Engine. We’re implementing an AI-driven BOM service that not only auto-reconciles materials but also suggests solid alternatives and finds the best ways to cut costs using a combination of rules and machine learning. And, of course, there are versioned change logs and approval workflows to make sure everything is tracked.
    • Adaptive MRP Engine. We’re building an MRP engine that actually cares about what’s going on in the real world, using IoT to drive inventory levels, automating the replenishment process, and looking at multi-site planning from all the right angles ( including time-phased, lot-sizing, and lead-time offsets).
    • What-If Simulations. We’re providing a capacity module that lets you simulate different scenarios, work out where the bottlenecks are, and even run what-if scenarios on a digital twin of your plant. And once you’ve got the results, we expose them via a reliable API.
    • Predictive Planning Engine. We’re embedding ML models at the core of demand forecasting, risk assessment, and resource allocation, using data from inside and outside the company. And we’re keeping a close eye on drift, making sure SLAs are met, and integrating with feature stores.
    • Scalable Planning Platform. We’re designing the core as a bunch of microservices on AWS or Azure, then adding an event backbone, making sure it scales horizontally, keeping security tight with zero-trust controls and CI/CD pipelines, and of course, having all the right SLOs, dashboards, and incident playbooks in place.

    You’ll get your planning cycles down to a fraction of what they used to be, using dynamic, finite-capacity schedules, cutting inventory costs using DDMRP and automated replenishment, and seeing forecast accuracy improve to around 85%. If anything goes wrong on the shop floor, it can be corrected in real time — get visibility across multiple plants that standard packages just can’t match, and make leadership decisions that much faster with a unified analytics layer — roughly twice as fast, in fact.

  • Legacy System Refactoring

    We’re modernizing legacy MRP into a cloud-based, AI-connected system that preserves essential business rules while learning from live shop-floor and IoT signals and integrating cleanly with engineering change control to operate as the plant’s central nervous system.

    • Codebase Dependency Mapping. We use AI to dig out the business logic that’s hidden in the code, then build up a picture of all the different parts that depend on each other, and that lets us create a priority list of which bits to fix first, along with a risk assessment to boot.
    • Guided Legacy Refactoring. We use special software agents running in the IDE to take the existing code and convert it into cloud-friendly patterns, where we can point-and-click our way through the refactoring, with automated reviews and updates along the way.
    • Regression Safety Net. We generate unit and end-to-end tests from the live system activity, and then compare them to our ‘gold standard’ recordings to make sure we didn’t break anything along the way, with clear targets for what we need to cover.
    • Compatibility-Safe Platform Upgrades. We do framework upgrades, making sure they’re compatible with all the existing parts, and if we need to, we add in some extra safety nets to double check we’re not breaking anything. And to be sure, we test it on a small part of the system first, a ‘canary’ release to make sure it all still works.
    • Secure & Governed Modernization. As we do the refactoring, we make sure we’re keeping track of all the rules and regulations, enforcing our data security standards, with data hiding, secrets check-up, and full audit trails to keep track of what’s going on.

    You get a whole new system that can match how fast you need to go on day one, with a cloud setup that just keeps on updating, and in the end, all your data flows together in one place, not stuck in separate silos. That lets you make faster decisions from a single source of truth, and your code finally keeps up with the best packages available.

  • AI-Powered Demand Forecasting

    We set up a continuous feedback loop so that our demand forecasting and predictive planning can learn from past data, get some extra context from outside sources like how long it takes for suppliers to deliver stuff and weather, and then incorporate real-time info from your manufacturing equipment to build plans that can adjust to supply chain changes or shifts in demand.

    • Production-Grade Demand Forecasting. We build our own custom models (things like those temporal fusion transformers and gradient-boosted ensembles) that are tailored to your specific business and seasonality/promotion stuff, we throw in some test data, and we expose an API that lets you get predictions in real-time.
    • Real-World Data Integration. We set up systems to bring in data from all sorts of outside sources: market trends, weather forecasts, and even data from your shop-floor equipment, all with some basic guidelines for how it all fits together, and check that nothing is getting held up.
    • Supply & Demand Risk Modeling. We make some predictions about where things might go wrong and use what-if scenarios to see how your business would do under different circumstances, like if a supplier is running behind or prices are about to jump.
    • Closed-Loop Planning Automation. We use the forecasts to sort out what orders to put in and how to best use your resources, all with built-in checks to make sure nothing goes wrong and the ability to step in and correct things if needed.
    • Drift Control. Weautomate retraining your models from time to time, check to see if there’s a problem with them, and give you a look at their performance so you can make informed decisions.

    This helps you achieve up to 85% forecast accuracy and maintain optimal stock levels, keeps working capital low, lets your whole team make decisions together, and gets rid of all those pesky spreadsheets locked in silos somewhere

  • Advanced Production Scheduling

    We deliver a transparent, operator-approved production scheduling software for manufacturing that uses a digital twin with hybrid optimization and machine learning.

    • Dynamic Algorithms. We’ve put together hybrid solvers that use a bit of machine learning and some mathematical optimisation to generate and continuously tweak finite-capacity plans as demand, resources, and constraints change, and every decision we make is recorded so you can see exactly how we came to our conclusions.
    • Live Production Feedback. Weuse machine and line telemetry to trigger updates to your production plan almost in real-time, with a bit of buffering and error-checking to keep things running smoothly and a human in the loop to double-check things.
    • Plant Modeling. Webuild detailed models of your plant, and use them to simulate different scenarios, like what happens if a machine breaks down or if something changes in the market — to see what the best course of action might be and to give you a clear idea of the potential risks and rewards.
    • Maintenance-Aware Scheduling. Wetake into account predicted failure rates and planned maintenance windows to make sure your schedules are always taking into account the health of your assets and the availability of spares and skilled labour to get the most out of your plant and cut unplanned downtime.
    • Cloud-Scale Production Optimization. We deploy large-scale mathematical optimization and machine learning in the cloud to find the perfect balance between cost, throughput, lead time, and environmental impact, and we scale up and down easily without sacrificing any transparency or auditability.

    The upshot of using our manufacturing production scheduling software is that you get production plans that update in seconds when something changes. And because we validate everything through your digital twin, you end up with faster production times and better use of your cloud resources.

  • IoT & Real Time Data Integration

    We connect machines, sensors, and MES/SCADA systems all together into one big data feed that your MRP can actually rely on to make real-time decisions for a second at a time

    • Industrial Data Ingestion. We get our edge agents and collectors up and running, establish a solid data schema, and set up a tested pipeline that gets inventory and equipment states flowing into your MRP with a reliable, predictable delay.
    • Operational Dashboard. We provide an operator dashboard that includes tools for anomaly detection, root cause analysis, and alerting tied to Service Level Objectives, so teams can actually take action based on what the data is telling them.
    • Real-Time Digital Twin Sync. We keep the digital twin of the plant in perfect sync with what’s actually going on on the shop floor, and expose an API for scenario planning that lets planners try out different scenarios in a simulated environment before they actually get put into production.
    • Logistics Connectivity. We give you secure APIs and connectors to ERP, suppliers, and logistics, so material movements and shipments can actually update plans all the way through the end-to-end process.
    • Secure Data Backbone. We design a cloud-edge system that’s zero-trust, with encrypted data flows, rotated certificates, offline buffering, and over-the-air updates, so data keeps flowing, and stays safe.

    With custom MRP systems for manufacturing, you get instant re-planning on machine or quality issues, fewer manual lags and silos, lower downtime and inventory levels, and faster decision-making from unified analytics.

  • Seamless Integration & Migration

    We ensure a seamless transition by integrating your manufacturing ERP software and custom MRP through a cloud-first, hybrid cutover.

    • Production-Safe Integration. We take the hassle out of integrating your existing MRP with your ERP and legacy platforms and do it all in a way that doesn’t skip a beat.
    • Interoperable Planning APIs. We create a solid API layer that effortlessly ties in SAP and Oracle and MES, with some super-useful low-code extensions that let you set your own pace with versioned contracts and no-nonsense SLAs.
    • Phased Data Cutover. We do phased cutovers using dual-write and change-data capture with built-in validation — all so your production team never has to miss a single beat.
    • Hybrid Cloud Transition. We help you get set up on AWS or Azure and design secure network paths, then make sure your on-prem and cloud systems stay in perfect sync with continuous data updates.
    • Controlled Data Synchronization. We give you a two-way sync with deterministic ordering, and some super-useful governance tooling that lets you enforce environments, approvals, and version control.

    All of this adds up to one fantastic benefit: you get to ditch the silos and have just one live data plane — get faster leadership decisions out of a unified analytics layer, and run operations that are more resilient and much more manageable, with plans that always stay in sync with real orders and supplier changes, and quality and traceability that stays linked to production, and a cloud migration that delivers continuous updates and scalable capacity, without the usual big-bang outages.

  • Cybersecurity & Compliance Implementation

    We secure your MRP environment with a zero-trust, encryption-first architecture that proves compliance with standards like ISO, FDA, and FAA while scaling resilient controls across cloud-based, multi-site, and supplier-integrated manufacturing systems.

    • Zero-Trust Industrial Security. Weget micro-segmentation and access control rights, with a system that constantly verifies who is doing what on your network, services, and users, across the board.
    • Incident Response. Webring in machine learning detectors that can spot suspicious activity and a ransomware pattern. We make sure that any unusual activity gets contained, audited, and dealt with properly.
    • Automated Compliance Evidence. Weturn the principles from NIST CSF, IEC 62443, and ISO 9001 into a set of automated checks that spit out a regular stream of evidence to help you prove your company is on top of things and isn’t falling behind, and runs a regular ESG report.
    • End-to-End Data Protection. Weencrypt data as it’s moving around and sitting still with end to end encryption, signed payloads, and a way to track the journey of your data and get the suppliers to keep it that way too by putting in place hardened APIs and so on.
    • Resilience Planning. Wekeep a close eye on all the vulnerabilities that could pop up, whether it’s due to a disaster or any other reason, and take a disaster recovery test with targets set for RTO/RPO — all aligned to the operational risks of Industry 4.0

    You get the satisfaction of knowing you’re compliant with NIST/IEC 62443/ISO, along with an airtight audit trail, continuous monitoring to keep ahead of any threat,s and the peace of mind knowing you’ve got a recovery plan in place, which means your production stays up and running without the panic when audit comes calling.

  • Post-Launch Support, Scaling & Continuous Improvement

    After go-live, we run your MRP as a cloud-native, real-time platform with measurable performance goals, disciplined change management, continuous updates, elastic scale, and AI-driven planning tightly integrated with MES, SCADA, and IoT.

    • Always-On System Monitoring. We’ve always got an eye on things with telemetry that’s always on, and using AI to predict any problems you might have, fix them without anyone even noticing, and get your team sorted before it starts to cause any real issues.
    • Infrastructure Optimization. We set up autoscaling and give your system a bit of a tune-up to ensure that it can handle increasing loads without slowing down, keeping your costs under control at all times.
    • Continuous Model Improvement. We keep our AI models sharp on the latest data, only ship new versions when they’re accurate and fast enough, and always check the water before taking the plunge.
    • Feature Enhancements. We get new features out there in small, bite-sized chunks that are properly tested and validated on a virtual twin before they go into production.
    • User Adoption. We give you training that’s tailored to your role, plant a flag for the champions on the shop floor, and rehearse any disasters you might have, so your team is confident in the system and can bounce back fast.

    With a robust MRP system for manufacturing industry, you get measurable stability and a strong return on investment.

Our Process

From Reality in Your Factory to a Planning System You Can Rely On Every Day

A successful manufacturing production scheduling software starts with getting a clear picture of how things really work on the shop floor. Clarity about the constraints that shape what happens with your materials, capacity, quality, and deliveries is vital. Our process is built to get that clarity on the table from the very start, translate it into a workable plan, and keep it going all the way to delivery, use, and long-term scale.

01.

01. Mapping the Real World

In any effective MRP system for manufacturing, we create a model that mirrors the way your factory really works. We start by getting a deep understanding of how work flows through your factory. We map out discrete, process, or mixed production models, including things like bills of material, recipes, batch behaviour, rework flows, changeovers, how well your stuff turns out, and what happens with quality. All the little things that people on the shop floor know intuitively. We get all those things down on paper. This step is what gets everyone on the same page — planners, operations, and engineering — and makes sure we're working with a planning model that actually reflects what's going on in the real world.

02.

02. Getting Your Data in Order

We make sure planning is working with real-world boundaries. Planning in any MRP software for manufacturing system is only as good as the data it's fed. We take a close look at things like how long they take you to get materials from suppliers, the best route to take for making the product, what your capacity is, how well your suppliers perform, what your inventory is telling you, and how well your quality controls are working, and then we get those all aligned in a way that makes sense. This creates a planning system that stays sane when things go off track in the real world.

03.

03. Introducing Your Planning System to the Rest of the Factory

We make sure your planning system is part of the whole factory ecosystem A good production planning system needs to be able to talk to the rest of the factory. We design production planning software for manufacturers to work smoothly with your ERP, MES, quality systems, warehouses, and suppliers. We get the data flowing continuously from your production floor into planning, so you can stay on top of what's happening and react in real-time.

04.

04. Getting Value Out of Your New Planning System

We deliver improvements in stages, so you can see real gains fast. We don't try to get everything done at once. Instead, we work in stages, one area of planning at a time (like materials, capacity, schedulin,g etc.), and we test each stage in real-world scenarios before opening it up to the whole factory. This way you can see real gains fast, and we're not asking you to make any big bets on a system whose performance you can't rely on.

05.

05. Getting Your Planners To Trust and Use Your New System

We design the system to be something planners want to use. A planning system only works when planners trust it to give them good advice. We design the system so that planners can see how the recommendations are being made, and where they need to jump in to help. We get the training out, and we make sure that planners feel confident and in control of the system.

06.

06. Making Your Planning System Do More As Your Factory Grows

We keep planning ahead as the factory evolves. Once we've got the system up and running, we keep fine-tuning it to make sure it's still working well. Maybe your forecasting models need to change, or maybe the way you're sourcing materials is shifting. We keep the system current so it stays a valuable tool for your business.

Benefits

Our Benefits

01

Stable Plans as Complexity Grows

Your Master Production Schedule remains stable as things get more complicated. Most planning breakdowns start off quietly, with master data getting stale, units of measure all over the place, duplicate materials, and changes happening left and right across all your plants. At Devox, we treat master data as a vital part of your production infrastructure, not some box to be ticked. We build in governance from the get-go: rules of ownership, versioning, approval channels, and validation checks that cover materials, BOMs, recipes, routings, and suppliers. This means that your planning logic stays consistent across all your sites, prevents data from slipping off the radar, and keeps your team confident in the numbers even months down the line.

02

Zero-Downtime Cutover

Your factory keeps running while we keep tweaking the system. When you're working with MRP, you're right in the thick of your manufacturing operation. We design our updates to work around your need for continuity. We create phase-by-phase rollouts, parallel planning windows, carefully controlled activation times, and clear paths for getting back on track in case something goes wrong. Every update includes a clear plan for rolling back, points to check the system isn't broken, and safe options for if things do go wrong. This lets your team keep moving forward, even in high-pressure or highly regulated environments.

03

Transparent Planning Decisions

Every suggestion comes with context, and someone to kick up the stairs if it all goes wrong. Only then can an advanced manufacturing resource planning system really drive value, when everyone sees why a particular decision has been suggested. At Devox, we design MRP systems that lay out the trade-offs in plain sight, between service levels, inventory, capacity, cost, and risk, whether you're working with discrete, process, or mixed manufacturing models. And scenario planning, dealing with exceptions, and getting AI to make recommendations all remain transparent and traceable. Your planners will see why a change is being suggested. Your operations team will see the impact. And your leaders will see the financial and operational consequences before committing to anything.

Built for Compliance

Industry Regulations We Master

Every custom manufacturing MRP software we build aligns with the regulatory, quality, safety, and data-governance frameworks that manufacturers operate under, with continuous updates as standards evolve. This ensures planning, execution, traceability, and reporting remain production-ready, audit-ready, and scalable across plants and regions.

FAQ

Frequently Asked Questions

  • What features should a custom MRP system include?

    A custom MRP system starts with production logic, getting to grips with how a plant actually runs, rather than just relying on a generic list of features. The core features of the system will depend on how manufacturing is set up in the plant. Discrete environments require a bit more complexity — you’re talking multi-level BOM management, routing, finite-capacity scheduling, and all the engineering change control that feeds neatly into the actively running plans. Process manufacturing, on the other hand, is all about recipes, batch sizes, yields, quality control checkpoints, and all that data that needs to be tracked back through lots. And then there’s the mixed manufacturers, who have to deal with both worlds, which puts a huge amount of pressure on the planning logic — it needs to be able to handle rework, last-minute customisations, and all the changeovers without forcing the schedules to go off track or mess with the inventory alignment. A custom MRP system should straightforwardly reflect these models, so that planning behaviour matches the way production actually works on the shop floor, rather than trying to shoehorn operations into a fixed structure that just doesn’t fit.

    Beyond just modelling production, modern MRP systems rely on feedback and having a solid data foundation that gets regularly updated. You get real-time signals coming in from MES systems, IoT, inventory, and quality control — all feeding into planning almost as it happens. That means workflows can be set up to focus on what needs attention in real time, rather than being bogged down with lots of stuff that doesn’t need it. You need master data governance that keeps an eye on your materials, recipes, routing, and suppliers as things get more complicated. You also need versioning and approval processes to keep everything in line as the complexity builds up. Then there are the advanced demand forecasting, finite-capacity planning, and scenario analysis tools that let you understand the trade-offs before they cause trouble downstream. All these features combined create a planning environment that stays solid even when things get really volatile, can scale up across different sites, and gives planners and leaders the confidence to make decisions.

  • How much does it cost to develop custom MRP or production planning software?

    The cost of a custom-made MRP system isn’t something you can just put a price tag on — its actually driven by how complex your production process is. You need to think about the type of manufacturing you’re doing (discrete, process or a mix), how many plants you’ve got, what kind of planning horizons you’re looking at, how deep you need to integrate it with your ERP system, your MES, IoT, and how good your existing data is in the first place. If we’re talking one factory running a straightforward discrete operation with healthy master data and stable production routes then that’s one thing, but if you’re running a multi-site operation that’s producing lots of different products, dealing with engineering changes all the time, juggling a bunch of suppliers and getting real time feedback then you’re going to need a completely different approach. What we find with MRP systems for small manufacturing business is that the cost reflects just how much of the real world of your business needs to be taken into account and represented within the software.

    Custom MRP systems tend to spread out the costs of the development over several phases of delivery rather than trying to get the whole thing done in one hit. The early stages of a bespoke MRP solution focus on the bits that will make the biggest difference to your daily planning. With each phase that follows, you can start to see the business benefits of having this kind of system in place — lower inventory levels, better forecasting, fewer scheduling conflicts, etc. As the system gets more developed its capable of handling more complex tasks such as running different scenarios, managing multiple plants, and doing some pretty heavy number crunching, and the great thing is that all the later stages build on the foundation that’s already been laid. This means that you can see the financial benefits coming through all the way, rather than waiting till the end of the project to see if it’s all paid off.

  • How does custom MRP software compare to off-the-shelf solutions?

    The difference really comes to a head when things start to get messy on the production floor. Off-the-shelf MRP systems rely on these canned planning models that are supposed to fit most manufacturers, but the problem is that they only really work okay in environments that don’t change too much. They can handle the basics when production is super stable, and processes are all standardised, with minimal changes and not too much variation. But when manufacturers start doing things like mixing up different production modes, making a lot of last-minute engineering changes, dealing with highly unpredictable demand, or coping with all the different quirks of different suppliers — all that stuff that keeps production managers up at night — the predefined models just can’t keep up with how things really play out on the shop floor. Planning teams end up having to make it up as they go along, and before long, even the most cautious planners start to lose faith in the system because exceptions are becoming the new normal.

    On the other hand, custom MRP software is all about making the system work with the way your plant actually operates. You get to model the specific mix of discrete, process, or mixed manufacturing that’s unique to your business, and then you get the system to learn from what’s really happening on the shop floor in real time. Changes get fed directly into the plans, and you get to really see what’s going on with your capacity — what you can actually do vs what you’re supposed to be doing. And with that level of visibility into what’s going on, planners become a lot more confident in the system, and that leads to a whole lot less resistance to change, and a whole lot more visibility into what’s going on across different sites and product lines. In short, one approach tries to make the factory fit into a pre-made template, and the other adapts to the reality of how the factory is actually working on a daily basis.

  • How long does it take to develop a custom MRP system?

    Custom MRP systems take as long to develop as the job itself takes to get done, and that’s not just a calendar estimate. It depends on loads of things like the kind of manufacturing you’re doing, how many sites you’re managing, and just how tightly integrated all that is — let’s not forget how mature the planning process is to start with. Environments that just make one thing at a time with a steady Bill of Materials and routing lists are going to be a lot faster than mixed-up processes or mixed manufacturing operations, where recipes, batch sizes, quality controls, and all the rest drive your planning needs. And if you’re managing a bunch of plants across different sites, suddenly you’re talking about coordinating inventory, capacity, and suppliers — big time.

    Because of that, building a custom MRP system usually unfolds in a series of chunks rather than just one big build. Modern programs like to deliver practical bits of functionality one at a time in order of what the business really needs. Usually, the first few phases focus on the basics of planning like figuring out what you need, how to fit it all in, or what your customers are actually asking for. And then as the system gets more and more real time capable, you can start building in feedback from your production systems, experimenting with scenarios, and coordinating across all your different sites — all the while checking to see how it all actually works in the real world.

    This way of working is pretty standard in 2025, by the way — planning systems grow and evolve along with the team’s growing confidence and readiness to really use them, so you can see the benefits right from the start, even before the whole thing is finished.

  • How can custom MRP software integrate with ERP, MES, or inventory systems?

    Custom MRP doesn’t exist on its own — it’s just a part of the manufacturing puzzle. ERP systems handle all the financial, procurement, and master record stuff, while MES and inventory systems are like the eyes and ears of the shop floor, capturing all the data on what’s actually happening. By getting these systems talking to each other, you create a data flow that lets your production plans reflect what’s really going on in the factory — things like how much stock you’ve actually got, what state your machines are in, what the quality results are, and whether your suppliers are on track.

    When you order stuff, make a forecast prediction,s or create material requirements, all those bits of information get passed on downstream. At the same time, feedback from the shop floor gets fed back into the planning system, keeping your schedules and commitments in check with what’s actually happening on the ground.

    This sets up a closed loop — near real-time replanning that kicks in as conditions change on the production line or in the supply chain. If a machine slows down, a batch fails quality check or a supplier is late with a delivery — all that info goes straight to the planning engine, and it can pick up the pace without delay. Over time, this sort of integration helps you get a better handle on capacity utilisation, inventory control, and making decisions across the company as a whole. Eventually, your MRP, ERP, MES, and inventory systems all start working like one system, and as a result, planners and leaders can make decisions based on what’s really going on, rather than what the last snapshot said.

  • What technologies are best for building modern MRP or production planning systems?

    In 2026 and beyond, cloud MRP software for manufacturers needs a solid architectural foundation to adapt to changing production landscapes. And that foundation is cloud-based, offering up the flexibility and scalability you need to handle multi-site planning and the constant evolution of your production planning rules.

    Using an event-driven approach lets changes in the system, like new material movements, production events & quality results, or supplier updates — kick off a response in the planning engine as and when they happen, rather than waiting for a scheduled recalculation. This means you get near real-time planning responses across discrete, process, and mixed manufacturing environments, even as the conditions on the shop floor shift throughout the day.

    Taking this as a starting point, you can add in advanced planning tools like machine learning models to help with forecasting, anomaly detection, and parameter tweaking — models that operate to help guide decision making, not as some kind of black box automation. Digital twins let you run what-if simulations across different scenarios like capacity, routing, and changeover constraints, helping you understand the potential trade-offs before you make a decision.

    Secure APIs joining together systems like ERP, MES, IoT, and supply chain platforms into a single data plane aren’t just useful — they’re essential. And as your operation grows and gets more complicated, governance and observability tools help you keep an eye on data quality. Put all these technologies together, and you get a planning system that stays adaptable, transparent, and reliable even as your operation expands and changes.

  • How can custom MRP software improve production efficiency and reduce costs?

    Production efficiency really starts to take off when your planning is in tune with the real-world challenges you’re facing, and you can adjust to changes as they happen. When you’ve got a custom MRP system in place, you can ditch the excess inventory and focus on getting the right materials to the right place at the right time, not just relying on some static forecast that’s probably going to be off the mark. Using finite-capacity planning keeps things realistic and prevents you from overcommitting. You get real-time feedback from your MES, inventory, and quality systems to make changes on the fly as production is underway. As a result, your production teams don’t have to deal with last-minute changes, your lead times get shorter, and your schedule starts to command some real credibility in discrete, process, and mixed manufacturing environments.

    Cutting costs comes from making better decisions, not just chasing some fancy optimization goal. You get better at making predictions, so you don’t have to lock up as much working capital in safety buffers. Then your planners can focus on what really matters — the exceptions that are going to mess everything up, and not have to spend all their time messing around with spreadsheets. When you tie your capacity plans in with machine health, quality, and supplier reliability, you end up with less downtime. And all these little improvements just keep piling up: you streamline your planning cycles for precision and consistency, you don’t get caught off guard as often, and your leadership team can make decisions faster because they’ve got a crystal clear view of what they’re working with, and the trade-offs they need to make on cost, service level, and throughput.
