Why people switch
Not another generic contractor app
Most invoicing apps are built like office software shrunk onto a phone. This is built around the moment you finish the job.
The old way
Too much typing. Too much delay.
- Type on a small screen with dirty hands
- Re-enter repeat client details
- Manually sort VAT and totals
- Tell yourself you will do it later
SayInvoice
Built to get the invoice out now
- Speak naturally from the van or on site
- Reuse repeat client details by name
- Keep UK VAT and payment details tidy
- Send the PDF by WhatsApp or email
What this looks like

The point is not “AI.” The point is getting from a spoken job note to a clean invoice fast.
“Demo Customer, 14 Example Street, boiler refit, £1,000 parts, £600 labour, £75 call-out fee, add VAT.”

FAQ
Questions people ask before they try it
Short answers for tradespeople who want to know what the app does, who it is for, and how pricing works.
Who is it for?
SayInvoice is made for UK tradespeople like plumbers, electricians, builders, heating engineers, locksmiths and other mobile service businesses.
Do I need to type?
No. The main workflow is voice-first. Speak the client, the job, the amount and the VAT details, then review and send.
Does it remember repeat clients?
Yes. Once a client has a saved invoice, the app can reuse their saved details on the next invoice.
Can I send it by WhatsApp?
Yes. The goal is to get a professional PDF invoice ready to share from your phone by WhatsApp or email.
How much does it cost?
There is a founders rate of £4.99/month, with a standard price of £7.99/month after the early rate ends.
Is this a web app or an app?
It is built mobile-first and is being shipped like an app. You can try the web demo now, with App Store and Google Play versions coming next.
Can I send invoices on site?
Yes. That is the whole point. Speak the job, check the invoice, and send it while you are still on site or back in the van.
