Most UK workshops hit the same wall. You have outgrown spreadsheets and paper job cards, but every off-the-shelf system you trial wants you to change how you work. Your approval process does not fit their template. Your commission structure is not supported. Your parts supplier is not in their integration list. So you end up running the software alongside the spreadsheets, and nothing really improves.
We build custom workshop management software for UK garages, fleet operators, and specialist repair businesses. The system matches your workflows, connects to the tools you already use, and handles UK-specific compliance from MOT audit trails to Making Tax Digital. You own it outright, with no per-user fees that inflate as you hire.
Where off-the-shelf workshop software falls short
The SaaS market for workshop management is large and fragmented. There are strong products for straightforward single-location garages. But once your operation has any complexity, you start hitting limitations:
- Per-user pricing that scales against you. Most platforms charge £20-100 per user per month on top of a base fee. A 15-technician shop can easily spend £300-500 a month before adding any extras. That is £18,000-30,000 over five years just on seat licences.
- Rigid workflows. SaaS tools expect a fixed process: job in, work done, invoice out. If your shop requires manager sign-off on jobs over a certain value, multi-stage inspection approvals, or technician-specific commission calculations, you are forced into workarounds.
- Weak or missing UK integrations. Few platforms integrate natively with DVLA for vehicle lookups, DVSA for MOT compliance, or TecDoc and Autodata for parts data. Most UK-specific features, like MOT reminders or MTD-compatible VAT reporting, are either absent or bolted on.
- No native parts supplier connections. Almost no SaaS tool syncs directly with major UK suppliers like Euro Car Parts or Halfords Trade. Technicians end up re-keying parts orders manually.
- System instability and slow support. User reviews frequently report system crashes during peak invoicing times, data sync failures when internet is unreliable, and slow support response from vendors in different time zones.
- Data portability problems. There is no standardised export format across platforms. Moving away from a SaaS vendor means rebuilding your data, often at significant cost.
- Limited niche support. If you specialise in EV repair, marine engines, HGV fleet maintenance, or exotic vehicles, generic platforms are optimised for standard automotive and require constant workarounds.
Teams end up maintaining parallel systems: the SaaS tool for invoicing, a spreadsheet for scheduling, a WhatsApp group for technician updates. The subscription fee is only part of what you are paying.
What we build instead
Software shaped around your workshop
We spend time in your workshop, talk to your technicians, receptionists, and managers, and document how work actually flows. Then we build software that supports those processes rather than overriding them. If your approval chain has three stages, the system has three stages. If your parts ordering works through a specific supplier API, we connect to it.
One cost, no per-user fees
You pay for the build, and you own the result. No monthly seat licences, no feature tiers, no surprise price hikes. For workshops with 10 or more staff, this is usually cheaper than SaaS within two to three years, and the gap only grows after that.
Genuine UK compliance
MOT audit trails that satisfy DVSA requirements. GDPR-compliant data handling with right to erasure and data export. Making Tax Digital compatibility through your accounting integration. We stay current with regulatory changes, including the stricter DVSA documentation rules that took effect in January 2026.
Integrations that actually work
We connect directly to the systems your workshop depends on:
- Accounting: Xero, QuickBooks, Sage (real-time sync, not manual export)
- Payments: Stripe, PayPal, card terminals
- Parts data: TecDoc, Autodata for parts lookup and specifications
- Vehicle data: DVLA registration lookups
- Communication: Twilio or SendGrid for automated SMS and email reminders
- Calendars: Google Calendar, Outlook for technician and manager schedules
- Legacy systems: ERP, CRM, telematics, or proprietary databases via custom API work
Most SaaS platforms support Xero and Stripe at best. We handle the integrations others leave to Zapier workarounds or manual re-entry.
Built to grow with you
Adding a second location, a mobile service van, or a new specialisation does not mean migrating to a different platform. We extend what you already have.
Local team, your hours
We are based in London. Support happens during your working day, not across a time zone gap.

How the build works
Discovery and planning (2-3 weeks)
We document your current processes, interview your staff across roles, and define what the system needs to do. We also assess your existing data: customer records, vehicle histories, parts lists, and pricing. Data quality varies widely across workshops, and we plan migration and cleanup during this phase.
Phase 1 build (8-12 weeks)
We build a working MVP covering job cards, scheduling, invoicing, customer and vehicle records, basic inventory, and SMS reminders. You see progress at regular check-ins and can steer direction as the system takes shape. We run the new system in parallel with your existing processes so your workshop stays operational throughout.
Phase 2 build (6-8 weeks)
Once the core is live and stable, we add the mobile technician app, accounting integration, customer portal, and reporting dashboards. This phase also covers digital vehicle inspections, multi-location management, and any specialist modules your workshop needs.
Training and go-live
We run role-specific training: receptionists on booking and invoicing, technicians on the mobile app, managers on reporting and configuration. We handle the data migration from your old system or spreadsheets, including deduplication and cleanup. Go-live is phased, with the old system kept available as a fallback until everyone is confident.
Ongoing support
Twelve months of included support and updates. After that, you choose whether to continue with our maintenance plan or bring it in-house. Either way, you have full documentation, source code, and deployment guides.
What it costs
Custom development costs more upfront than a SaaS subscription. But the long-term economics usually favour a custom build, especially for workshops with 10 or more staff.
SaaS costs over time (illustrative):
- A mid-size shop with 12 users on a mainstream platform typically pays £15,000-20,000 over three years, or £25,000-35,000 over five years
- Larger operations with 20+ users can reach £36,000-60,000 over three years
- Add in setup fees, data migration, premium support, SMS volume charges, and integration costs, and the real number is often higher
Custom build costs:
- A functional MVP for a single-location or small multi-location workshop: £40,000-80,000
- A full-featured system with mobile app, advanced reporting, multi-site management, and integrations: £100,000-200,000
- Highly specialised builds (EV-only, HGV fleet with telematics, complex approval hierarchies): £150,000+
The breakeven point for most workshops with 10+ staff is two to three years. After that, you are saving money every year while running software that fits your business exactly. And there are no per-user fees holding back your hiring decisions.
When SaaS is probably fine
Not every workshop needs a custom build. If you run a single-location garage with standard repair workflows, fewer than 10 technicians, no unusual compliance requirements, and you are happy adapting your processes to the software, a SaaS tool will likely do the job. Products like Garage Hive, Workshop Software, or Garage Invoice serve this market well.
Custom makes sense when you have outgrown that model: non-standard workflows, niche specialisations, multiple locations with different rules, legacy systems that need connecting, or a team size where per-user pricing becomes painful.
Industry-specific builds
Workshop operations vary significantly by sector. Here is how we approach the most common ones:
Automotive repair and MOT centres
MOT scheduling with DVSA-compliant audit trails, automated MOT and service reminders, technician allocation by certification, parts ordering integration, and warranty claim tracking. For franchise chains, we add multi-location approval hierarchies and centralised reporting with regional breakdowns.
Fleet operators and HGV maintenance
Predictive maintenance scheduling based on mileage, age, and usage patterns. Compliance tracking for O-licence requirements, driver and operator certifications, and regulatory inspections. Multi-bay coordination for large depots, downtime minimisation workflows, and integration with telematics systems for fault data.
Mobile mechanics and field service
Offline-capable mobile app with local data storage and sync. Route planning with travel time built into scheduling. Parts inventory management per van. On-site invoicing and payment collection. Customer location mapping and job dispatching to the nearest available technician.
Marine and leisure vehicle workshops
Specialised service categories covering engines, hulls, electrical, and rigging. Project-based tracking for multi-week refits with customer portal visibility. Niche supplier management for marine-specific parts. Winter storage scheduling and seasonal preparation workflows.
Specialist and EV repair shops
Custom service categories for high-voltage battery work, specialist diagnostics, and certification tracking. Parts hierarchies for components that do not appear in standard auto parts databases. Technician qualification tracking for EV-specific safety certifications.
Construction plant and agricultural equipment
Equipment servicing schedules tied to operational hours rather than mileage. Operator certification tracking with expiry alerts. Seasonal preparation workflows for agricultural machinery. Multi-site asset tracking across depots and client locations.
Common Questions About Custom Workshop Management Software
How does custom development cost compare to SaaS workshop software?
SaaS workshop tools typically cost £60-400 per month, plus £20-100 per additional user. For a shop with 10 technicians, that adds up to £3,000-5,000 per month or £36,000-60,000 over three years. A custom build for an SME workshop usually runs £40,000-80,000 for an MVP, with no ongoing per-user fees. Most workshops break even within two to three years and benefit from lower costs every year after that.
What's the typical development timeline?
A working MVP covering job cards, scheduling, invoicing, and basic inventory takes around 8-12 weeks of development after a 2-3 week discovery phase. Phase two, which typically adds a mobile technician app, accounting integration, a customer portal, and reporting, follows in weeks 9-16. Full-featured systems with multi-location management, MOT compliance, and advanced analytics usually complete within 6-9 months.
How do you handle updates and changes after launch?
We include 12 months of support and updates. After that, you can continue with our maintenance plan or handle updates in-house. You get full documentation, source code, and deployment guides. Because you own the system, you are never locked into our support if you prefer to bring it in-house.
Can you integrate with our existing systems?
Yes. Common integrations include Xero, QuickBooks, and Sage for accounting; Stripe and PayPal for payments; Twilio and SendGrid for SMS and email reminders; TecDoc and Autodata for parts data; and DVLA for vehicle lookups. We also connect to legacy ERP, CRM, and telematics systems where off-the-shelf platforms typically cannot.
What about MOT compliance and Making Tax Digital?
We build in DVSA-compliant audit trails for MOT testing, including test records, defect logging, tester identification, and date tracking. MTD-compatible VAT reporting is handled through your accounting integration. GDPR data handling, including right to erasure and data export, is built in from day one.
Do you provide training for our team?
Yes. We run role-specific training: receptionists get 2-3 hours on booking and invoicing; technicians get 3-4 hours on the mobile app and job cards; managers get 4-6 hours on reporting, scheduling, and system configuration. We also provide user manuals and can do on-site sessions for larger teams.
When does custom workshop software make more sense than SaaS?
Custom typically makes sense when you have 10 or more technicians (where per-user SaaS fees become expensive), non-standard approval workflows or commission structures, niche specialisations like EV repair or marine engines, multi-location operations with different regional rules, or integration requirements with legacy systems that SaaS tools do not support. For a single-location garage with standard repair workflows and fewer than 10 staff, a SaaS tool is usually fine.
