How to use invoice numbers
Invoice numbers should be unique and if you are VAT compliant, this is a requirement
When creating an invoice, in the Invoice options screen you'll see Invoice number.
We'll populate the next sequenced invoice number automatically for you. For example, if your previous invoice number was INVOICE-001 then we'll auto-populate INVOICE-002. If you like, you can start invoicing with at a higher number.
If you tap (or click) on the text box you can edit the invoice number to anything you like using standard UK alphanumeric characters, including some common symbols like - # /.
If you've made a mistake with an invoice
You can cancel an open invoice from the Get Paid tab in the app and on Web. If you've already shared the invoice with your customer, it's best to let them know you've cancelled it straight away.
Then you can duplicate the cancelled invoice and correct the mistake. If you like, you can use the same invoice number as the cancelled invoice.
You can read more about invoicing requirements on the government website.
