What custom facility management software costs to build in 2026, the modules it needs, build vs buy, timeline, and where IoT and ERP integrations fit.
Custom facility management software costs roughly $30,000 to $60,000 for an MVP built around work orders, assets, and preventive maintenance, and $90,000 to $180,000 or more for a department-wide platform with space planning, IoT sensors, and ERP integration. A mid-range system with a mobile app and a few integrations usually lands between $40,000 and $90,000. Off-the-shelf CMMS tools run $20 to $99 per user per month, so building tends to win once your team is large, your workflows are unusual, or your buildings already produce sensor data you want to use.
| Scope | Typical cost | Timeline | What it covers |
|---|---|---|---|
| Work-order MVP | $30,000–$60,000 | 2–4 months | Work orders, asset registry, preventive maintenance, basic reporting |
| Multi-module platform | $40,000–$90,000 | 4–7 months | The above plus a mobile app, inventory, vendor and contract tracking, integrations |
| Department-wide platform | $90,000–$180,000+ | 6–10 months | The above plus space planning, IoT and energy data, compliance, ERP migration |
These are planning ranges, not quotes. The final number depends on integrations and on how many buildings, sites, and roles are in scope.
Work orders are the core. A technician opens a job, attaches photos, and closes it; the manager watches backlog, response time, and cost. This one module carries most of the daily value, which is why the cheapest MVP usually stops here.
Preventive maintenance scheduling turns reactive work into planned work. You set intervals by runtime, calendar, or meter reading, and the system generates jobs automatically. Emergency repairs typically cost several times what the same job costs when planned, so this module usually pays for itself fast.
The asset registry stores equipment details, location, warranty, and repair history, often with QR codes or NFC tags so a technician can scan a machine and see its full record on a phone. Space and room management maps occupancy and moves against floor plans, which matters for offices and landlords. Reporting and dashboards come last; a system that collects data but cannot show cost per building or per asset will not get used.
Most of the budget is engineering. Roughly 60 to 70 percent goes to development, with the rest split across design, QA, and project management. The cost drivers are specific, not mysterious: the number of modules, whether there is a mobile app, how many systems you integrate, and whether you migrate historical asset data.
A two-to-four-month MVP with one mobile app and no integrations fits the $30,000 to $60,000 band. Add inventory, vendor and contract management, and two or three integrations and you are in the $40,000 to $90,000 band. A department-wide system with space planning, IoT sensor ingestion, compliance workflows, and a data migration from a legacy CMMS or spreadsheets pushes past $90,000, and enterprise deployments with energy management and ERP connectivity commonly reach $180,000 or more.
Team size moves the timeline more than the price per hour. A typical build runs four to six people: two to three developers, a designer, a QA engineer, and a project manager. This is the same composition GlobeSoft uses for business systems, built on Java, Spring Boot, MySQL, Redis, and Vue or React, with Go or Python where real-time sensor pipelines are involved. A detailed scope before any code is written keeps the estimate honest; see how a discovery phase works.
For a single site with standard maintenance, buying is often right. SaaS CMMS pricing in 2026 is well documented: UpKeep starts around $20 per user per month, Fiix around $45, and Limble around $28, with enterprise tiers reaching $100 to $130 per user. Heavy enterprise products like IBM Maximo can run near $10,000 a month even for a small team. None of these prices include setup, training, or data migration.
Custom building wins in a few specific situations. Your maintenance or space workflow is the product itself, or the source of your cost advantage. You run multiple buildings and the per-user license math scales badly. Your buildings have IoT sensors, and a vendor tool will not ingest them without expensive add-ons. You need the system to talk to your ERP, accounting, or tenant portal, and you want to own the data. Or you sell facility services and need your own branded, multi-tenant platform. In those cases, a subscription becomes a recurring constraint rather than a saving, and this mirrors the custom software vs SaaS decision more broadly.
Integrations, not screens, usually decide whether a project is simple or large. An ERP or accounting link, to SAP, Oracle, or a finance system, lets work orders create purchase orders and costs flow into the ledger. A building management or BAS link over BACnet or Modbus pulls in HVAC and lighting data. IoT sensors for occupancy, temperature, or energy add a telemetry pipeline that a generic CMMS will not handle, and this is where IoT platform development and enterprise software development overlap.
Tenant and visitor systems, access control, and booking tools are the smaller but common ones. Each integration is a data contract, so the cost depends on whether the target system has a clean API or a file export. Our related guides on asset management systems, field service management, and workforce management cover the neighboring systems a facility build often touches.
GlobeSoft is a software development company founded in 2018 with 40-plus engineers and 300-plus delivered projects across the US, Brazil, South Africa, and Singapore. For systems like this we start with a one-to-three-week discovery sprint that produces the module list, the integration map, and a fixed estimate. Because facility projects sit at the edge of property and IoT, we reuse work we have already done on property and rental management systems rather than pricing every screen from zero. The team communicates in English and works across time zones, which matters when a deployment spans sites in several countries.
An MVP runs $30,000 to $60,000, a multi-module platform $40,000 to $90,000, and a department-wide system $90,000 to $180,000 or more. These are planning ranges; integrations and data migration push a project toward the top of each band.
An MVP takes two to four months, a multi-module platform four to seven months, and a department-wide system six to ten months. Most of the extra time is integration work and data migration, not new screens.
A CMMS focuses on maintenance: work orders, assets, and preventive scheduling. CAFM adds space management and room booking. IWMS is the enterprise layer that ties maintenance, space, real estate, and sustainability into one system. Most companies start with CMMS scope and grow from there.
Buy when you have one or a few sites with standard maintenance. Build when your workflow is the product, license costs scale badly, you have IoT data, or you need deep ERP integration. The build vs buy line is rarely about features and usually about data ownership and recurring cost.
Work orders, an asset registry, preventive maintenance scheduling, a mobile app for technicians, and basic reporting. Skip space planning, energy analytics, and advanced integrations until the core is used daily.
Only if you plan to act on sensor data. Occupancy, temperature, and energy sensors add a telemetry pipeline and real cost, so add them when the insight changes a decision. A system that collects sensor data nobody reads is pure overhead.
