Disconnected systems, work orders tracked on spreadsheets and paper, and a software bill that climbs every renewal. Most off-the-shelf facilities management tools, whether they call themselves CAFM, CMMS, or IWMS, expect you to bend your operation around their templates. ByteGears does it the other way round: we build custom facilities management software that fits how your team, your sites, and your assets actually work.
There are no per-user licence fees with a system you own outright. We’re a small London consultancy, and a lot of our work is with UK businesses managing maintenance, assets, and contractors across one site or fifty who got tired of renting software that almost fit.
Where off-the-shelf facilities management software falls short
Generic CMMS and CAFM platforms work fine for a single site with standard assets and a simple “technician raises it, manager approves it” workflow. They start to creak when your operation is more involved. The complaints we hear most often:
- Rigid workflows. Off-the-shelf approval chains assume one path. Real facilities work is messier: a £6,000 job needs finance sign-off, a safety-related fault needs to escalate to your HSE officer, and routing should follow your cost centres.
- Flat asset hierarchies. Many tools assume Building to Floor to Equipment. They struggle with sub-systems, component-level tracking (filters, belts, motors inside an HVAC unit), and non-standard kit like lab equipment or production machinery.
- Per-user pricing that scales against you. At £20-£75 per technician per month, costs grow faster than your team. Advanced reporting, API access, and a usable mobile app are often locked behind higher tiers.
- Re-typing between systems. Weak integration, especially with UK accounting tools like Sage and FreeAgent, leaves someone keying cost data by hand.
- Compliance gaps. Tools built abroad rarely handle UK obligations well: HSE incident reporting, GDPR audit trails, UK data residency, or sector inspections like CQC and Ofsted.
- Mobile apps technicians avoid. Slow interfaces, poor offline support, and lag when uploading job photos mean field teams quietly fall back to paper.
You end up paying for the workarounds. A lot of buyers come to us paying for features they never touch while still missing the ones they need.
What you get with a custom build from ByteGears
Designed around your process We map how work orders are raised, approved, and closed, and how your asset hierarchy actually looks, before anyone writes code. Approval workflows match your organisation, not a vendor’s default.
One cost, not a forever subscription You pay once for development and own the software, source code, and data model. No per-seat licensing, no premium tier paywalls.
Connects to what you already run We build integrations to your accounting or ERP (Xero, Sage, SAP, Oracle, QuickBooks), Microsoft 365 or Teams, and where it helps, your building management systems and IoT sensors.
UK compliance built in UK GDPR, HSE workflows, and audit trails are part of the system from the start, with sector-specific checklists for CQC, Ofsted, or MHRA where they apply.
Built to scale across sites Start with one location, expand to a multi-site portfolio without a painful platform migration or months of vendor configuration workshops.
Support from people nearby Our London team runs the rollout and stays available during UK business hours.
Features and modules we typically build
Every build is shaped around how you operate. Most include some version of these, delivered in phases rather than all at once.
Work order management Raise, assign, prioritise, and close jobs. Priority levels, job types (preventive, corrective, inspection, safety), linked assets, parts and labour cost, and a full approval chain with audit trail.
Technician mobile app A field app that works offline and syncs when it reconnects, for inspections and work orders. Photo capture, checklist evidence, QR code asset scanning, and GPS tagging where sites are remote or connectivity is poor.
Asset and equipment register Manufacturer, model, serial number, location, warranty expiry, supplier, cost, and full service history. Support for sub-systems and component-level tracking, not just a flat list.
Preventive maintenance scheduling Servicing triggered by calendar interval, usage hours, or sensor threshold. Conditional logic where it earns its place, such as scheduling a major overhaul once an asset passes an age and runtime point.
Vendor and contractor management One contractor database with SLA terms, response times, insurance records, cost history, and performance scoring. RFQ, quote approval, and purchase order workflows where you rely heavily on third parties.
Parts and inventory Stock levels, reorder points, supplier links, and which assets consume which parts.
Compliance and audit trails HSE incident and near-miss logging with corrective action tracking, GDPR access logs and retention rules, and inspection checklists for the regulators that apply to you.
Multi-site dashboards and reporting Work order ageing and SLA tracking, asset utilisation, budget versus actual cost, and a custom report builder pulling exactly what your KPIs need.
Space and floor plan management Interactive floor plans for room use, desk allocation, and booking shared spaces.
Energy monitoring (where it applies) Live IoT feeds for consumption by zone, equipment efficiency tracking, and reporting that supports ESG and carbon targets.
How the build works
Discovery and planning (2-4 weeks) We sit down with your facilities, maintenance, and finance people to map current processes, asset structure, integration points, and what is not working today.
Data preparation and design (2-4 weeks) Migration is the part most teams underestimate. We audit your legacy asset register, dedupe and cleanse it, and agree a target hierarchy before anything is imported.
Phase one development (build the core first) Work orders, the technician mobile app, the asset register, template-based preventive maintenance, accounting integration, and role-based access with GDPR audit logging. This is the release that goes live.
Testing and go-live (1-2 weeks) User acceptance testing with the people who will actually use it, then a monitored cutover with escalation support.
Phase two and beyond Conditional PM logic, multi-site dashboards, vendor management, parts inventory, capital planning, deeper compliance reporting, and energy monitoring, added once the core is bedded in.
A focused first release usually runs four to six months. Multi-site portfolios with ERP integration and compliance modules tend to run six to nine months. We would rather get a working system in your technicians’ hands early than chase every feature request before go-live, which is one of the most common ways these projects stall.
What it costs, and why it’s worth it
A custom build costs more upfront than a subscription. Over a few years, the maths usually flips.
- No per-user fees. CMMS pricing of £20-£75 per technician per month adds up fast as headcount and site count grow, and that is before implementation, data migration, training, and per-location charges.
- No premium tiers. The reporting, API access, and mobile features you need are not held behind an upgrade.
- You own it outright, IP and data included, with no three-year minimum contract or exit penalty.
- No expensive platform migration when your portfolio changes shape.
As a rough guide, a single-site or small multi-site build with standard integrations and GDPR compliance is a smaller project than a multi-site portfolio with ERP integration, complex approval workflows, and sector compliance modules. The actual figure depends on asset count, how many sites, and how much it has to connect to. The consultation is free, and we give you a real number once we understand the job.
How this works across different sectors
The same approach is shaped differently depending on the sector:
Property management Coordinate maintenance across residential and commercial portfolios, with tenant communication and cost allocation per building.
Healthcare Track servicing and validation records for medical equipment, infection control and fire safety audits, and CQC and MHRA audit trails. Cost allocation against departments for internal billing.
Education Premises maintenance and health and safety records ready for Ofsted, classroom and shared-space booking, and capital planning across a multi-campus estate.
Retail chains Run facilities across 50 to 500-plus sites, with HVAC and refrigeration schedules, contractor coordination, energy tracking, and audit trails.
Manufacturing and industrial Critical production equipment maintenance to limit downtime, IoT sensors for predictive maintenance, spare parts control, and HSE near-miss reporting.
Corporate offices and real estate HVAC, lighting, and access control maintenance across multi-floor buildings, hot-desking and room booking, energy management, and tenant coordination in multi-let buildings.
Hospitality Fast response to maintenance issues affecting guests, seasonal asset preparation, and consistent standards across a chain.
Local government and public sector Public asset accountability with full audit trails, compliance reporting, multi-site portfolios, and budget transparency for oversight.
Logistics hubs Warehouse equipment servicing and dock scheduling across distribution sites.
Leisure centres Pool plant maintenance tracking, safety inspections, and facility bookings.
If you are weighing up custom against a CMMS subscription, the honest answer is that off-the-shelf is often enough for a single site with standard assets and simple approvals. A custom build earns its place when your workflows, asset hierarchy, integrations, or compliance obligations do not fit the template, or when you simply want to own the system rather than rent it. We are happy to tell you which side of that line you are on.
Common Questions About Custom Facilities Management Software
How does a custom build compare in cost to CMMS subscriptions?
Per-user CMMS pricing usually runs £20-£75 per technician per month, so 50 technicians can mean £30,000-£45,000 a year before implementation, integrations, and per-site fees. A custom build is a larger upfront cost with no per-seat licence, so the maths often turns in your favour within two to three years, especially if your headcount or site count is growing. We give you a real number after we understand your asset count and integration needs.
What's a realistic development timeline?
A focused first release covering work orders, a technician mobile app, asset records, and preventive maintenance usually takes four to six months. Multi-site portfolios with ERP integration and compliance modules tend to run six to nine months. We scope a phase one that goes live early, then add advanced reporting, vendor management, and energy monitoring afterwards rather than delaying everything for one big launch.
Can you migrate our existing asset and maintenance data?
Yes. Migration is usually the part teams underestimate. Legacy asset registers tend to have duplicates, missing serial numbers, and inconsistent locations, so we run a data audit and cleanse before importing. We typically migrate the full asset master and the last 12-24 months of work order history rather than everything, and map your assets to a sensible hierarchy first.
Can it integrate with our accounting and building systems?
Yes. Common integrations are accounting and ERP packages such as Xero, Sage, QuickBooks, SAP, or Oracle for cost and purchase order data, plus Microsoft 365 or Teams for scheduling and notifications. Where it adds value we connect to building management systems and IoT sensors so preventive maintenance can be triggered by runtime hours or sensor thresholds, not just the calendar.
How do you handle GDPR, HSE, and sector compliance?
UK GDPR is built in from the start: access logging, role-based permissions, retention rules, and UK data residency where you need it. We can build HSE workflows for incident and near-miss reporting with corrective action tracking, plus sector-specific audit trails and checklists for CQC, Ofsted, or MHRA where they apply. The audit trail records who changed what, when, and why.
Who owns the software and the data?
You do. You own the source code, the data model, and the data itself, with no per-user licence and no long-term contract locking you in. You decide when the system changes and who hosts it. We can provide a support arrangement for enhancements, but you are never forced into an update you did not ask for.
