⚠️ Not Employment Law or HR Advice
Employment law, worker rights, and HR compliance are highly regulated and complex. This guide provides general information only and should not be used as a substitute for professional legal or HR advice.
Before hiring employees or engaging workers: Consult an employment solicitor or HR professional. Requirements for contracts, PAYE, National Insurance, holiday pay, minimum wage, and worker classification (employee vs contractor) vary by situation and change frequently.
Incorrect worker classification or employment practices can result in tribunal claims, HMRC penalties, and significant back-payments.

Why time tracking is a compliance problem now
The Toolfy Scaling Bottlenecks review from 17 Nov 2025 documented that SMS onboarding and manual record checks jump to 10–15 hours per week once you’re onboarding 50+ new customers (SCALING_BOTTLENECKS_SOLO_FOUNDER.md, lines 90-104). That same backlog applies to timesheets: if you can’t reconcile hours fast, you pay overtime twice—once in wages, again in tribunal settlements.
Working Time Regulations require retaining proof of hours for two years (source: gov.uk/maximum-weekly-working-hours). HMRC also expects overtime adjustments when you go over the 48-hour average unless employees signed an opt-out. No signed timesheet = you lose disputes immediately.
- 48-hour average cap unless you have written opt-outs.
- Night work limited to 8 hours per 24-hour period—requires medical surveillance.
- Need rest records for at least two years and ideally stored per vehicle/crew.
Signals you need to overhaul timesheets
- Technicians texting dispatch to add travel time later (no GPS proof).
- Payroll team manually editing CSVs each Friday.
- Customer complaints about “phantom hours” that you cannot disprove.
- Average job duration in Toolfy exceeds paid hours by 10%+.
Reality Check
ACAS claims and HMRC audits rarely question your software. They question evidence. Build a workflow where every Technician → Job → Timesheet entry inherits GPS, photos, and signatures automatically.
Build an audit-ready timesheet workflow in Toolfy
Use this order of operations so you’re not rewriting policies mid-investigation.
- Baseline actuals. Export Toolfy job durations for the last 4 weeks and compare them to payroll hours. Anything beyond ±10% variance becomes remediation priority.
- Publish the policy. Use a short handbook addendum covering clock-ins, meal breaks, drive time, overtime approvals, and disciplinary outcomes. Reference ACAS guidance to keep it defensible.
- Configure Toolfy mobile. Turn on GPS-required status transitions, enforce photo uploads at arrival/departure, and lock timesheets until the photo exists.
- Automate approvals. Use Toolfy automations so crew leads sign off on their team’s hours nightly. Late approvals trigger reminders in Slack or email.
- Store exports centrally. Drop final CSV exports + signed policy PDFs inside Documents
/HR/Timesheets/2026so every record lives beside the job history.

Many tribunals award 1.5× pay on missing overtime records. Estimate the share of hours that would qualify.
Monthly wage leakage
£1,091
Base pay you lose to sloppy check-ins and untracked travel.
Revenue left on the table
£2,533
Billable work that disappears because timesheets lag behind.
Overtime risk (monthly)
£327
Potential tribunal back pay if HMRC/ACAS audits missing overtime records.
Annual exposure: £17,016 in wasted payroll plus potential £30,396 in lost billable work. Tight GPS + photo-backed time tracking in Toolfy plugs the hole instantly.
Coach with data every Monday
Run a Monday morning dashboard (Jobs → Reports → Time Variance) highlighting missing entries, jobs with >120% quoted time, and technicians who forgot to end shifts. Repeat offenders get 1:1 coaching, then disciplinary notes if it happens thrice in a quarter.
Automate time checks with ChatGPT Apps
Toolfy’s ChatGPT Apps integration lets you push time entries or reminders via PAT-authenticated tools (docs/CHATGPT_APPS.md). When your GPT spots “Arrived at job in 5” in a conversation, it can call /api/jobs/:id to add a time log, provided you pass the headers below.
Required headers (per docs/CHATGPT_APPS.md)
Authorization: Bearer <PAT>– Issue tokens in Settings → Security.x-org-id– Targets the right workspace.Idempotency-Key– Re-use it when retries happen so duplicate time logs collapse automatically.x-agent: chatgpt– Rates + observability treat automation separately from humans.
Store those headers in your GPT action manifest exactly like the quick start example so every time entry respects the same scopes and rate limits.
Pair that with Toolfy Automations: when a technician forgets to clock out for 30+ minutes after “Job Complete,” send them an SMS + in-app ping reminding them to close the timesheet before payroll locks.

Stop writing off 5 hours a week
Toolfy makes every job status, timesheet, and payroll export live in one place. GPS-backed check-ins, SLA reminders, and ChatGPT-powered workflows mean fewer disputes and faster payroll.
