How to create an invoice number numbering your invoices sequentially, for example, INV00001, INV00002. starting with a unique customer code, for example, XER00001. including the date at the start of your invoice number, for example, 2023-01-001. combining the customer code and date, for example, XER-2023-01-001.

There are no rules as to the invoice numbering system, apart from them being alphanumeric (they may include numbers and letters). Invoice numbers typically don't contain special symbols or characters.

You can use a sequential, alphanumeric, or even client name/project system to assign invoice numbers, but the most important thing is to make sure the numbering is unique. That said, creating unique numbers for invoices should not be tedious when using accounting or invoicing software as it automates the process.

They should be assigned sequentially, meaning that the number of each new invoice increases. Legally, an invoice number sequence should never contain repeats or gaps. It's not recommended to simply number invoices '1', '2', '3', etc. as this can be confusing when invoice numbers reach double or triple figures.

A chronological invoice number includes not only a unique number but also the date of the issuance. This method is exploited to avoid disambiguation, ensuring the invoices from the same day won't end up with duplicate numbers. Chronological invoice numbers usually look like this: 20220928-001, 20220928-002, and so on.
