What it looks like
Worked example
You finish the job and text GraftG:
With your hourly rate set to £45.00, a numbered PDF invoice with your bank details comes back in the chat:
| Line | Amount |
|---|---|
| Labour (5 hours × £45.00/hour) | £225.00 |
| Roof tiles | £96.00 |
| Tower hire | £45.00 |
| Total due | £366.00 |
Example figures — GraftG uses the rate you set and prices a day as 8 hours. Not VAT registered here; if you are, VAT at 20% is added and shown on the invoice. Forward the PDF to your customer, then reply PAID when the money lands. The full how-to is in our guide to invoicing on WhatsApp.

Yes. The Job Tracker records real time on site, so if rain stops play your invoice reflects the hours you actually worked rather than a rough estimate. That removes the awkward negotiation with the customer and protects your margin on weather-dependent roofing jobs.
Snap every receipt on your way out of the merchant and GraftG categorises it and extracts the VAT before you are back on the roof. Tile and slate receipts from three different suppliers end up in one organised, MTD-ready place.
Yes. Voice-note the scope from the roof and a branded PDF quote comes back in about 30 seconds, so you can price a leak repair on the spot. It all runs through WhatsApp with no app to open while you are up top.
Yes. Text each trip and GraftG totals your mileage for the week and month and calculates the HMRC value. Five jobs a day with 20 miles between them no longer go unlogged. GraftG costs from £14 a month with a 14-day free trial.
