How to Invoice as a Sole Trader

What your invoice must show

Put your own name (or trading name) and contact details at the top, then the client's name and details. Add a unique invoice number, the date you send it, and a due date. List each service or product with a short description and its price, then show the subtotal, any tax, and the total due.

Finish with how to pay you. As a sole trader that is usually your bank details, printed clearly on the invoice so there is nothing standing between the client and paying.

Do you charge tax?

Only if you are registered for it. Many sole traders and freelancers sit below their country's registration threshold and do not charge VAT or GST at all. If you are registered, add it at the correct rate and show your registration number. If you are not, simply leave tax off. Our guide on charging VAT covers the threshold question in more detail.

Number every invoice

Give each invoice a unique, sequential number like INV-2026-0001. It keeps your records straight for tax time and looks professional. A good tool numbers them for you automatically so you never repeat or skip one.

Send it the day you finish

The fastest way to get paid sooner is to invoice sooner. Send it the moment the work is done, while the client is happy and the job is fresh. A clear due date and your banking on the page do the rest.

Keep clean records for tax time

Save every invoice you send and every receipt you issue in one place. As a sole trader your bookkeeping is only as good as your records, and a tidy trail turns tax time from a scramble into a formality.

Keep your numbers sequential so nothing looks missing, note when each invoice is paid, and hold on to the documents for as long as your tax authority requires. A tool that stores your invoices for you means the record builds itself as you work.
