WhatsApp invoice generator
Generate an invoice from a WhatsApp message.
A WhatsApp invoice generator takes the details you send in chat and turns them into a proper, formatted UK invoice — PDF, line items, totals and all. With WOPA, the message is the form.
How it works
You message. WOPA generates.
Instead of opening an app and filling in fields, you describe the job in a WhatsApp message — the customer, what you did, and the amount. WOPA reads that and generates a formatted invoice with your business details, line items and totals. You get a PDF back in the same chat, ready to send.
The output is a normal UK invoice. It contains the same information any invoicing tool would produce; only the way you create it is faster. For people who already run their day through WhatsApp, that removes the step of switching to separate software just to bill a job.
Two ways to start
Chat-first, or in your browser.
| Option | Best for |
|---|---|
| WhatsApp generator (WOPA) | Invoicing from your phone, in the flow of the chat with the customer. |
| Free browser generator | One-off invoices, or when you are already at a computer. |
WOPA generates invoices; it is not full accounting software. For bookkeeping or MTD filing, see the accounting comparison.
