Every job showing live gross profit — not just hours.

Green if you’re on track. Amber if the margin is tightening. Red if you need to act. You see it while the job is live — not after you’ve invoiced it and the damage is done.

AI Business Assistant

Ask your business anything. Get a straight answer.

The AI knows your live jobs, cashflow, staff and overheads. Ask it whether you can take on more work, which jobs are dragging your GP down, or what your most profitable work type is — and get a real answer based on your actual numbers.

AI Assistant

You

Can I afford to take on another roofing contract next month?

Grafter Lab AI

Based on your 12-week cashflow, taking on a contract worth £18k keeps you above your buffer throughout. The Grange lead costs are running high though — worth getting that under control before committing.

You

Which jobs are dragging my GP down this month?

Grafter Lab AI

Northfield School is your biggest drag at 6.2% GP against a 35% target. Lead costs have overrun by £620 and there’s 16 hours of labour over on the re-felt. Every other live job is above target.

Retention Tracker

Know exactly what’s held in retention — and when you can invoice it.

On commercial contracts, retention ties up cash for months. Grafter Lab tracks every retention amount, DLP period and expected release date so it feeds into your cashflow forecast automatically.

Frequently asked questions

Is Grafter Lab suitable for a sole trader roofer?

Yes. The Starter plan at £39/month covers up to 5 users and gives you job tracking, quotes, invoices, supplier invoice AI and Xero integration. Many sole trader roofers use it to get proper visibility on their job margins.

Can I track lead, tiles and felt costs on every roofing job in real time?

Yes. Every job shows live gross profit that updates as labour hours are logged and supplier invoices arrive. You see the margin changing while the job is live — not after you’ve invoiced and the damage is done.

Which roofing suppliers work with the supplier invoice AI?

Any supplier that sends a PDF invoice. SIG Roofing, Roofbase, Jewson, Travis Perkins, Marley and Redland all work out of the box. You give them your unique Grafter Lab email address once and their invoices are read and matched automatically.

How does GPS clock in work for roofers on site?

Your roofers download the Grafter Lab app on iOS or Android. When they arrive on site they open the app, select the job and tap clock in. GPS confirms they’re within the site boundary before the clock starts. Labour costs hit the job automatically.

Does it handle CIS for subcontract roofers?

Yes. Grafter Lab generates CIS-compliant subcontractor invoices automatically with the correct deduction rates, VAT treatment and payment statements all handled within the platform.

Does Grafter Lab integrate with Xero?

Yes. Invoices sync to Xero automatically when raised and payments sync back when marked as paid. Your accountant sees everything without you exporting spreadsheets or copying figures manually.
