Tenant Experience App Development

Let's Talk
  • ELEVATE THE RESIDENT EXPERIENCE

    Bring resident services into one app. Residents use one app for rent payments, maintenance requests, and mobile access while your teams work from one shared data source that reduces manual work.

  • DRIVE NOI & RETENTION

    Boost resident satisfaction and renewal rates with an easier mobile experience. By streamlining maintenance dispatch and automating routine inquiries, you cut manual work and improve NOI.

  • UNIFIED PLATFORM

    Bring your tools together into a single, cohesive resident experience. By unifying disparate tools and live ERP data from Yardi, MRI, or AppFolio, the platform gives your team one place to work.

Build or Keep Paying SaaS Fees?

Build or Keep Paying SaaS Fees?

Stop paying per-unit SaaS fees. We move you from recurring SaaS costs to own your software.

  • The TCO Model: We analyze your current per-unit SaaS fees over a 3-5 year horizon against a one-time development cost.
  • Asset Ownership: Unlike third-party tenant experience platform solutions where you pay indefinitely to access your own data, you gain the operational nimbleness to evolve your platform without depending on a SaaS vendor. You gain total operational independence while still benefiting from optional managed maintenance and future development to support your growing portfolio.
  • Scalability: As you add units, your cost per unit drops, lowering your cost per unit as you grow that scales with your portfolio.

As you add units, your cost per unit drops. This model scales with your portfolio.

We specialize in real estate software development services, helping property owners move from manual processes to automated operations.

Our Edge

Where Property Teams Get Stuck

  • Modernize
  • Build
  • Innovate

Legacy ERP slowing you down?

Yardi, MRI, and AppFolio stay in place. An API layer connects them, so leases and balances stay synchronized while existing workflows stay intact.

Too many disconnected tools?

Everyone works from the same data instead of maintaining disjointed copies across different systems.

Still onboarding tenants manually?

A signed lease automatically creates a resident profile, sends the portal invitation, and syncs with your PMS.

Maintenance requests falling behind?

Maintenance requests become work orders automatically. The system routes them to the right contractor without waiting for a dispatcher.

Need smarter guest access?

Residents issue a temporary digital key scoped to a single door and a limited time window, so guests can unlock doors from their phones.

Struggling with manual rent collections?

Payments post directly into your ERP, so accounting always has up-to-date balances without manual reconciliation.

Ready for AI-powered automation?

AI agents grounded in your actual ERP and sensor data reduce maintenance response times by 30% by automating verification and routing of work orders.

Too many competing priorities? Each release focuses on your biggest problem that's costing you the most today.

Each release solves your biggest bottleneck that's costing you the most today.

Locked into your vendor?

Avoid vendor dependency with a solution that provides full control over your platform and long-term autonomy from day one.

What We Deliver

Services We Provide

  • Turnkey Resident Experience Portal

    Residents use one app for everything. Everything runs through one portal connected to your ERP.

    • Rent Payment Hub. Stripe and PayPal connect directly to GL accounts. Payments automatically update your books, and the owner dashboard shows real-time delinquencies, vacancy, and cash flow.
    • Resident Portal. Real-time sync of leases and unit statuses appear in the portal; repair requests convert into work orders instantly.
    • Resident Engagement. Push notifications, amenity bookings, and service ratings keeping residents engaged after move-in.
  • Smart Access IoT Platform

    Smart thermostats, occupancy sensors, and digital keys connected to your property management system. You get real-time data on energy use, unit occupancy, and access history—without managing separate logins for every building system.

    • HVAC Automation. Integrate smart thermostats and climate sensors to dynamically adjust temperatures based on occupancy, reducing energy consumption by 15-25% in vacant zones.
    • Occupancy Analytics. Install occupancy sensors to track real-time space usage, showing see how spaces are used for floor plan optimization and space reconfiguration.
    • Indoor Air Quality Monitoring. Integrate real-time sensors for CO2, VOCs, and humidity to automatically optimize ventilation and filtration. Indoor air quality improves while meeting ESG and wellness certification standards.
  • Mobile Access & Digital Keys

    Tenants open doors directly from their phones. The app integrates with Salto KS and HID mobile access digital keys apartment technology. Guests receive temporary digital keys with limited time and scope. Your security team logs all access events without additional hardware.

    • Mobile Credentials. Tenants use encrypted BLE/NFC tokens for door access. Access stays secure and eliminates physical keycard reliance.
    • Access Logs & Analytics. Security teams see every access event and guest access history through a unified dashboard.
    • Remote Access Management. Property managers or residents grant or revoke digital key access for guests, service providers, or contractors. This provides security and convenience without exchanging physical keys.
  • PMS Sync with Automated Onboarding

    The tenant app stays synchronized with Yardi or MRI, so lease data, payments, and unit information stay current in both systems.

    • Lease Onboarding. Direct synchronization replaces manual CSV uploads. Tenant data, payment schedules, and move-in dates is added to the ERP automatically, shortening the lead-to-lease cycle from days to hours.
    • Financial Reconciliation. Real-time sync of accruals, receipts, balance adjustments, and GL accounts between the app and the ERP eliminates spreadsheet work. Accounting sees the exact debt status and closes audits without discrepancies.
    • Property Data Sync. We pull real-time data on units, availability, and property characteristics directly into the tenant app, so vacancy and pricing data stay aligned because every update follows the same data lineage.
  • Carbon Compliance & ESG Reporting

    The platform automates the entire carbon accounting cycle from telemetry to report submission for Local Law 97 and other regional carbon regulations. This eliminates the risk of fines and manual data collection errors from meters, providing property owners with a reliable path to compliance.

    • Carbon Accounting. Leveraging connected telemetry from smart electricity, water, and gas meters, we aggregate data into a centralized store to automatically convert consumption into CO2e equivalents, giving property owners near-real-time visibility into progress toward their emissions targets.
    • ENERGY STAR Reporting. We implement integration with ENERGY STAR Portfolio Manager and generate reports in a format ready for the Department of Buildings portal, which eliminates manual data transfer and reduces the risk of fines for late or incorrect reporting.
    • Resident Sustainability Dashboard. Your tenants get a dashboard with their real eco-footprint and energy usage trends, helping residents reduce energy use.
  • Agentic AI for Property Operations

    AI agents monitor equipment, intelligently route work orders, and reduce emergency maintenance before small issues become expensive repairs.

    • Predictive Maintenance Engine. AI analyzes sensor data from IoT sensors, elevator vibration, and HVAC compressor temperatures identifies early signs of equipment failure before failure occurs, so teams schedule repairs rather than reacting to emergencies.
    • AI Work Order Dispatch. Your agent analyzes photos or video of damage, determines the fault type, checks warranty status, and creates a work order automatically with an assigned contractor without a dispatcher.
    • Tenant Risk Scoring. AI analyzes payment history to predict delinquency risk. The management company secures payments or initiates legal proceedings before a cash flow gap occurs, reducing bad debt write-offs.
  • AI Resident Concierge

    The AI Resident Concierge automates repetitive inquiries and tenant needs. Leasing staff focus on high-value activities like renewals and tours.

    • AI Resident Concierge. The agent processes tenant requests around the clock and remembers previous conversations so each subsequent response takes past experience into account instead of starting the conversation from scratch.
    • AI Package Management. Lobby cameras recognize courier delivery packages, automatically document receipt, and send the tenant a notification in the app, eliminating staff time spent on package logging and reducing liability for lost shipments.
    • Amenity Booking. Your tenants book meeting rooms and coworking zones directly in the app with a real-time calendar, removing the need for administrative coordination.
  • Unified Enterprise Data Architecture

    A modern API layer replaces fragile data bridges while preserving data lineage across your property systems. You reduce long-term maintenance costs and eliminate manual data entry.

    • Yardi & MRI Integration. We synchronize the leasing lifecycle, GL accounts, and financial entries directly with Yardi or MRI, while preserving data lineage across both systems, eliminating manual duplication.
    • Legacy API Gateway. A cloud gateway wraps the legacy system and connects a modern mobile app without stopping business processes. Background syncs use secure session tokens without manual staff login.

FAQ

Frequently Asked Questions

  • What is a tenant experience app?

    A tenant experience platform unifies building access, service requests, payments, amenity booking, and communication in one mobile interface synced with property management systems like Yardi and MRI. Devox Software develops tailored apps for tenant experiences in US portfolios where off-the-shelf products hit their limits.

  • How smooth is integration with our existing Yardi or MRI system?

    Your team keeps the systems they already trust while tenants get a simpler mobile experience. A cloud API gateway connects the tenant app with your Yardi or MRI environment, so lease data, balances, service requests, and resident updates move automatically.

    Accounting and leasing teams stay inside their familiar ERP workspace. Tenants get fast self-service from the app. Synchronization rolls out in phases, with adjustments along the way as your portfolio grows.

  • Who owns the data once the tenant app goes live?

    Your company owns the data, the platform, and the roadmap, so you continue to hold the reins as the product evolves. Under our Managed IP model, you own the asset while Devox remains an optional partner for long-term maintenance and scaling, ensuring you have the support you need without the risk of being locked in.

    As your platform grows, that ownership gives your team the nimbleness to expand without depending on another vendor. Predictive maintenance works better with clean equipment history. Risk forecasting becomes stronger with reliable payment behavior. Portfolio analytics provide a single source of truth that your team can continue to build upon.

  • How secure is mobile door access for tenants and property teams?

    Mobile access leverages authorization through OpenID Connect and PKCE, protecting the app from token interception. Tenants receive short-lived access tokens. Each digital key remains tightly controlled across everyday use.

    Guest access follows the same rigorous logic. A tenant creates a temporary digital key for specific doors, with limited permissions and a fixed expiration time. Security teams track issued keys and access attempts through the platform. The building experience remains secure and simple for residents.

  • How dependable is Agentic AI inside a tenant experience platform?

    AI agents work best when they operate on structured property data, ERP records, IoT signals, and interaction history. When a tenant sends a photo of a leak, the agent classifies the issue, checks warranty context, and prepares the right work order using information your systems already hold. 

    The same data also supports predictive maintenance and risk forecasting. Models learn from telemetry, but engineers still hold the reins when business decisions require judgment. Your team sets escalation thresholds, so routine cases move faster and complex situations reach managers at the right moment. 

  • What happens after launch as the product starts scaling?

    You go live with a product your team owns, improves, and extends. The launch follows a plan designed around existing operations, ensuring leasing, accounting, service, and property teams continue working with minimal disruption while existing operations stay intact.

    After launch, support can focus on scaling modules, watching integration stability, improving tenant adoption, and adapting the platform as Yardi, MRI, access control, payment, or communication workflows evolve.

  • How long does it take to build?

    A core platform MVP typically takes 3-5 months from discovery to launch. We utilize an iterative, sprint-based approach to prioritize your highest-cost operational bottlenecks, such as manual payment reconciliation or emergency maintenance dispatch. You see measurable business value as early as possible while we continue to build out advanced modules.

  • Does the platform support rent payments?

    Yes, handling rent is a central capability of our resident experience portals. We integrate secure payment gateways directly with your existing ERP (e.g., Yardi, MRI). This ensures every transaction automatically updates your General Ledger and closes accruals, providing your team with a real-time dashboard of delinquencies and cash flow without requiring manual data entry or reconciliation.
