Around 40% of UK businesses are actively looking to improve how they track employee time and attendance. Most start with a SaaS product, and many end up frustrated. The software works well enough for simple clocking, but falls apart when it meets the reality of your overtime rules, multi-site rotas, payroll deadlines, and UK employment law.
We build custom time and attendance systems for UK businesses. You pay once, you own the code, and the software works the way your business does rather than forcing you to change. We are a London-based team that works mostly with SMEs, and we have learned that the real complexity in attendance systems is not clock-in and clock-out. It is the things around it: Working Time Regulations enforcement, leave accrual calculations, approval chains that match your org chart, and payroll integration that actually works without CSV exports and manual re-keying.
Where off-the-shelf attendance software falls short
SaaS time and attendance tools fail UK businesses in specific, predictable ways:
Per-user pricing that scales badly. Most SaaS products charge per employee per month. At around £4-5 per user, a 100-person team is paying £5,000-6,000 a year. A 500-person organisation is spending £25,000-30,000 annually, and that is before setup fees, add-on modules, or integration charges. Vendors have also been raising prices with little notice — one popular platform increased its per-user rate by over 10% in a single year.
Weak payroll integration. This is the single biggest complaint in user reviews. Most SaaS attendance systems promise payroll integration but deliver a CSV export that someone on your team has to manually import into Xero, Sage, or QuickBooks. Timesheet cutoff dates do not align with payroll cycles. Field mappings break. Custom leave types are not supported. The result is duplicate data entry, payroll errors, and slow month-end processing.
Rigid approval workflows. If your organisation needs multi-level approvals (team lead signs off, then manager, then director for overtime above a certain threshold), most SaaS products cannot accommodate it. You end up running the exception cases through email or spreadsheets, which defeats the purpose of having the system.
UK compliance as an afterthought. Global SaaS vendors design for multiple markets and treat UK Working Time Regulations as a secondary feature. Proper 48-hour weekly average tracking (over a rolling 17-week period), mandatory rest period enforcement, break compliance logging, and statutory leave accrual with pro-rata calculations for part-time staff are often missing or poorly implemented. You remain exposed to compliance risk and still need to check things manually.
Limited clocking methods. You might need web, mobile, kiosk, PIN, RFID badge, or biometric terminals depending on your workforce. Most SaaS products support two or three of these. Adding biometric hardware can cost £1,200-2,500 per terminal, and the vendor controls which devices are compatible.
No offline capability. Construction sites, warehouses, and rural locations often have poor mobile signal. Cloud-only SaaS products require a constant internet connection, which means missed clocks, manual corrections later, and unreliable records.
Vendor lock-in and data portability. Your attendance data sits in the vendor’s proprietary format. Exporting it for migration is difficult. Switching costs are high, which means you are stuck even when service quality declines or prices rise.
What we build instead
We design the system around your actual workflows, not a generic template.
Your rules, built in. Your shift patterns, overtime calculations, rounding rules, approval chains, and break policies drive the design. If your rota logic is unusual or your pay structure has specific overtime tiers, that is exactly where custom software earns its keep.
Payroll-first architecture. We build direct integrations with Xero, QuickBooks, Sage 50, and Sage Intacct so that approved timesheets flow straight into your payroll calculations. No CSV exports, no manual imports, no field mapping headaches. We handle the timing mismatch between real-time attendance data and batch payroll processing with proper queuing logic.
UK compliance from day one. Working Time Regulations enforcement (48-hour averages, rest periods, break requirements), statutory annual leave at 5.6 weeks pro-rata, GDPR-compliant data handling with audit trails, and biometric consent management are all built into the core system, not bolted on.
Fixed cost, full ownership. You pay a one-off development cost and own the result outright. No per-user fees, no per-location charges, no price increases. Adding a second site or a hundred more employees costs nothing extra in licensing.
Any clocking method you need. Web, mobile app, kiosk, PIN, RFID badge, fingerprint, or facial recognition. We integrate with the hardware that suits your environment and can add offline capability for sites with poor connectivity.
Approval workflows that match your organisation. Single-level sign-off for straightforward teams. Multi-level, conditional, delegated approvals for complex organisations. Escalation rules when managers do not respond within your SLA. A proper workflow engine, not a workaround.
Our team is in London. When something needs fixing, we are in the same timezone and available directly.

How the build works
Discovery and planning (2-4 weeks) — We map your current processes, identify where things break down, and write a specification. We document your shift patterns, approval chains, leave policies, payroll integration requirements, and compliance needs. You review everything before any code gets written.
Phase 1: MVP build (6-10 weeks) — We deliver core clocking (web and mobile), basic shift display, single-level timesheet approval, leave request and approval, and CSV export for payroll. This gets a working system into your hands quickly.
Phase 2: advanced features (4-8 weeks) — Based on what you actually need, we add GPS geofencing, multi-level approval workflows, direct payroll API integration, biometric terminal support, offline capability, or advanced reporting.
Testing and deployment (2-3 weeks) — We run parallel testing against your old system for at least two payroll cycles, do user acceptance testing with your staff, and handle data migration. We monitor the first two live payroll runs closely.
Training (included) — Employees get a 30-minute session on clocking and leave requests. Managers get 2-3 hours on dashboards, approvals, and exception handling. HR and finance get deeper training on compliance reporting and payroll exports.
Ongoing support — We remain available for fixes, changes, or additions on flexible terms.
Most projects take 3-6 months from start to finish, depending on complexity.
What it costs
Custom development costs more upfront than a SaaS subscription. But the total cost of ownership often tells a different story.
For a 50-person team: SaaS products typically cost £3,000-4,000 per year in per-user fees, plus setup fees (£2,000-5,000), plus integration costs and add-on modules. Over five years, you are looking at £18,000-25,000 or more. A custom build for this size usually runs £25,000-45,000 as a one-off cost with no recurring licensing.
For a 200+ person team: The maths tips firmly in favour of custom. Per-user SaaS costs for a 500-person organisation can reach £25,000-30,000 per year. Enterprise SaaS vendors (with custom pricing, implementation fees, and premium support) can cost £100,000-150,000 in year one alone. A custom build for this scale typically runs £80,000-150,000 as a single investment.
What affects the cost: The number of payroll integrations (each system adds roughly £5,000-15,000), approval workflow complexity, compliance depth (WTR enforcement, industry-specific rules), biometric integration, historical data migration, and offline mobile capability all move the price within the range.
What you avoid: Per-user fees that grow with your headcount. Per-location charges that penalise multi-site operations. Surprise price increases. Setup fees. Per-integration charges. Premium support upsells. Add-on module costs for features like advanced reporting or scheduling.

Industry applications
Construction
Multi-site crews need GPS geofencing to verify workers are actually on-site (not clocking in from the car park), job and project code assignment for labour cost tracking, offline clocking for remote sites with poor signal, and daily safety check-in logging. The typical trigger is a large contract requiring per-project labour allocation, or a growing crew that makes manual timesheets unmanageable.
Retail and hospitality
High staff turnover, shift-based rotas, and tight labour budgets require shift swap self-service, automatic overtime and premium wage calculation (weekends, late nights), real-time labour cost dashboards, and mobile-first clocking. Businesses usually reach for a system when they expand to multiple locations and payroll errors from manual timesheets start costing real money.
Healthcare
Rotating 24/7 rotas, on-call staff, and strict fatigue management rules demand mandatory break enforcement, rest period tracking, real-time coverage gap alerts, and facial recognition for hands-free clocking (useful when wearing gloves). WTR compliance is especially important here because of the safety implications of fatigued staff.
Manufacturing and logistics
Large hourly workforces on shift-based production lines need real-time floor occupancy dashboards, geofencing by production zone for safety compliance, biometric terminals, and tight ERP integration for job costing. Driver hour compliance for logistics teams integrates with fleet management systems.
Professional services
Law firms, consultancies, and accountancy practices need project-based time allocation with billable versus non-billable hour tracking, client code assignment at clock-in, and automated billing export to accounting systems. The trigger is usually scaling past 20-30 staff and needing accurate project profitability data.
Public sector
Pension scheme record-keeping, mandatory leave accrual per scheme rules, audit-ready records for public accountability, Freedom of Information data export, and union agreement compliance. Complex pay rules across different employee categories make generic SaaS tools particularly unsuitable.
Each build is scoped to what your industry actually needs, without paying for features that are irrelevant to your business.
Common Questions About Custom Time and Attendance Management Systems
How does the cost of a custom build compare to SaaS subscriptions?
For a 50-person team, a typical SaaS product costs around £3,000-4,000 per year in per-user fees alone. Over three years that is £9,000-12,000 before setup fees, add-on modules, and integration costs. A custom build for the same team size usually runs £25,000-45,000 as a one-off cost with no recurring licensing. For larger teams (200+ employees) the breakeven point often arrives within 18-24 months. You also avoid surprise price increases -- several SaaS vendors have raised per-user fees by 10% or more with little notice.
What is the typical development timeline?
An MVP with core clocking, basic leave management, timesheet approval, and CSV payroll export typically takes 9-12 weeks. More complex builds involving multi-site geofencing, biometric integration, or real-time payroll APIs take 16-24 weeks. We prioritise getting a working system into your hands quickly, then add advanced features in a second phase.
Which payroll systems can you integrate with?
We build direct integrations with Xero, QuickBooks, Sage 50, and Sage Intacct. We can also connect to legacy or proprietary payroll systems via API, SFTP file transfer, or database-level access. The goal is always to eliminate the CSV export-import step that causes errors and delays month-end processing.
How do you handle UK Working Time Regulations?
We build WTR compliance into the system from the start: automatic tracking of the 48-hour weekly average over a 17-week reference period, enforcement of 11-hour rest periods between shifts, mandatory 20-minute break alerts for shifts over 6 hours, and statutory annual leave accrual at 5.6 weeks pro-rata for part-time staff. Opt-out agreements are stored as auditable records within the system.
What about GDPR and biometric data?
All attendance data (clocking times, GPS location, biometric records) is personal data under GDPR. We build in encrypted storage (AES-256 at rest, TLS 1.2+ in transit), role-based access controls, audit logs for every data access, and right-to-erasure workflows. If you use biometric clocking, we ensure explicit written consent is captured and that a non-biometric alternative (PIN, card, web) is always available, as required by UK data protection law.
Do you provide training?
Yes. Employees typically need about 30 minutes to learn clocking and leave requests. Managers need 2-3 hours for dashboard use, timesheet approvals, and exception handling. HR and finance staff get deeper training on compliance reporting, payroll exports, and system administration. We include documentation and are available for refresher sessions afterwards.
What happens if we need changes after launch?
We offer flexible support arrangements, from ad-hoc fixes to scheduled maintenance plans. Because you own the code, you control when changes happen. There are no forced updates, no features removed without warning, and no vendor-imposed upgrade cycles.
