PDF invoices comparison
PDF invoices are the right format. WOPA makes them for you.
A PDF is the sensible format for an invoice — it looks the same everywhere and is hard to alter. The question is how you create it. By hand, or generated from a WhatsApp message. WOPA does the latter, and chases payment too.
Compare
Making PDFs by hand vs automatically.
| Need | WOPA | Manual PDF invoices |
|---|---|---|
| Valid PDF output | Yes — proper UK invoice. | Yes, if you build it correctly. |
| Create from WhatsApp | Message the details, get a PDF. | Build and export each time. |
| Consistent numbering and records | Handled automatically. | Manual — easy to slip. |
| Payment chasing | Built-in reminders. | Down to you. |
| Best fit | Anyone invoicing regularly who wants it faster. | The occasional one-off invoice. |
PDF is the right format either way. WOPA simply removes the manual steps between finishing a job and having a chased, recorded PDF invoice.
