What it looks like
Worked example
You finish the job and text GraftG:
With your hourly rate set to £40.00, a numbered PDF invoice with your bank details comes back in the chat:
| Line | Amount |
|---|---|
| Labour (2 days, 16 hours × £40.00/hour) | £640.00 |
| Bricks and mortar | £240.00 |
| Skip | £60.00 |
| Total due | £940.00 |
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.
