Sole trader invoice app
A Simple Invoice App for UK Sole Traders
Say the customer, the work you did and the prices in a voice note. Get an itemised invoice draft, check the details and send it from your phone — between jobs rather than after work.
Between jobs, in the van

Why do sole traders fall behind on invoicing?
When you are the whole business, invoicing happens after the real work — usually late at night, from memory.
Big accounting packages ask for far more than you need. Most sole traders just want a proper invoice out the door and paid on time.
SaidToPaid is a voice-to-invoice app for UK sole traders. It turns spoken job details into an itemised invoice draft that you review before sending; recording a note does not send an invoice automatically.
What is an invoice app for sole traders?
An invoice app for sole traders lets a one-person business create, send and track invoices from a phone without full accounting software. With SaidToPaid, say the customer, job details and prices in a voice note to create an itemised draft, then check the customer, amounts, VAT settings and payment terms before sending.
How does SaidToPaid work?
Record a voice note or type a line describing the job. SaidToPaid turns it into an itemised draft with the customer, each line and the price. You check it, then send it by email with a payment link.
What must a UK sole trader invoice contain?
Your name and business name, an address, the customer's details, a unique invoice number, the invoice date and date of the work, a description of what you supplied, the amount owed and payment terms.

VAT vs non-VAT registered sole traders
If you are not VAT registered, do not charge or show VAT. If you are registered, your invoice must also show your VAT number and the VAT amount. SaidToPaid supports both.
This is general guidance, not tax advice — check HMRC guidance or an accountant for your situation.
Can a sole trader invoice from their phone?
Yes. Invoices sent from a phone are just as valid as ones from a laptop, as long as they contain the required details. SaidToPaid is built to be used on a phone, between jobs.
How does voice invoicing work for sole traders?
You say one sentence. SaidToPaid turns it into separate, priced invoice lines.
“Invoice Mrs Patel for replacing the kitchen tap £85 and parts £32.”
