How to get the best result

SayInvoice works best when you say four things clearly: the client name and address, the job, the amount, and whether VAT applies.

Speaking tip

Use one simple format

Example: “Sample Customer, 14 Example Street, boiler repair, £150 labour, no VAT.”

  • Say the client name and address first.
  • Say the work done in plain language.
  • Say the amount clearly.
  • Say “plus VAT”, “20% VAT”, or “no VAT”.

Saved clients

Repeat jobs get faster

Once a client has a saved invoice, you can often just say their name again and SayInvoice can reuse their saved address and email.

  • Save a draft, sent invoice, or paid invoice once.
  • Next time, say the client name again.
  • The app can reuse the saved address and email when it recognises the name.

Before sending

Always do a quick check

The app is designed to save time, but you should still review the invoice before you share it.

  • Check client spelling and address.
  • Check line items and labour quantities.
  • Check VAT and totals.

Billing

Trial and upgrade

The app lets you try a small number of invoices first. When the free trial ends, you can upgrade to keep using unlimited voice invoicing at £4.99/month on the current founders rate.
