What each part is for
- A unique invoice number. Number them in order and never reuse one.
- Your name. As a sole trader your own name must be on it, even if you trade under a business name, plus an address for legal letters.
- Your customer’s name and address.
- The date of the work and the date of the invoice.
- What you’re charging for, line by line, with the amount for each and the total. Splitting labour and materials also helps if the customer is a contractor taking CIS deductions.
- VAT, if you’re registered. Show your VAT number and the VAT on each line. If you’re not registered, don’t add VAT. See when you need to register for VAT.
- A due date and bank details. Not required, but the easiest way to get paid on time.
There’s more on the rules in what to put on an invoice.
Send it from your phone instead
A template still means typing, saving and attaching. Kev’s invoices fill in your details, the next number and your bank details for you. Pick the customer, add the lines, and send a link they can open on their phone, or download the PDF. Kev shows you who has paid and who is overdue. It’s free for 5 invoices a month, and unlimited on Kev Pro.
