What it looks like
Worked example
You finish the job and text GraftG:
With your hourly rate set to £50.00, a numbered PDF invoice with your bank details comes back in the chat:
| Line | Amount |
|---|---|
| Labour (4 hours × £50.00/hour) | £200.00 |
| Sockets and cable | £38.00 |
| Total due | £238.00 |
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.
