Say hi
Message hi and it greets you by name. That first message also opens the line so codes and PDFs reach you instantly.
Send your first invoice
Type the job the way you'd tell a friend. Each item goes on its own line with a price — the currency symbol is optional. Any line under an item (with no price) becomes that item's description.
Check, then tap ✓
Nothing ever sends without your say-so. Tap ✓ Send it and the PDF lands back in your chat and in your customer's inbox — your logo, your banking details, a payment reference.
Change anything by talking
Tap ✎ Change and just say what's different. It shows the updated total and asks again.
Not ready? Save a draft
Reply DRAFT instead of sending — it's saved privately, the PDF comes to you only, and it doesn't use your daily free allowance. When you're ready, tap ✓ Make invoice (or reply MAKE 45) to issue it and email your customer.
It remembers your customers
Second job for Mrs Naidoo? Just her name is enough — email and details auto-fill. Spell it slightly wrong and it politely checks: "did you mean Mrs Naidoo?" — one tap.
Mark it paid
Money in? PAID 45 and the books balance. Your portal shows what's outstanding at a glance.
Late payers get chased (politely)
The moment an invoice goes past its due date, you get a nudge — not the awkward silence. One reply sends the customer a courteous reminder with the invoice re-attached.
Quotes win the work
Start a message with quote instead of invoice. When they say yes: CONVERT 12 — it becomes a numbered invoice, zero retyping. The paperwork is done the moment you win the job.
Month-end in one word
STATEMENT — issued, paid, outstanding for the month. Your accountant gets a tidy story instead of a shoebox.
The portal — your paper trail, searchable
Log in at whatinvoice.uk/app with your number — a code comes to your WhatsApp or email, no password to forget. Every document, filterable and downloadable. Add it to your home screen and it behaves like an app.
Make it yours
Portal → ⚙ Settings: upload your logo, pick one of three PDF styles, set your accent colour, banking details (protected by a WhatsApp code), VAT number if you're registered — and even what number your invoices start from. INV-1000 sounds established; that's allowed.
Grow into it
Free is 1 invoice + 1 quote a day, forever. Business unlocks unlimited documents, reminders and statements. Business Plus runs up to 3 businesses — each with its own logo, numbering and banking — from the same WhatsApp number. Reply UPGRADE or tap your plan badge in the portal.
Your data stays yours
Download everything as a ZIP or delete your account entirely — both in Settings, both instant, no phone call required. That's the whole alphabet. Now go send one: it takes less time than reading this page did.
