Define invoice and credit note numbering sequence/format

In Breww, you have the ability to define how you would like invoice and credit note number sequences to work. This allows for:

  • A prefix, such as INV- or CN-.
  • Defining the next number to use, such as 123.
  • Padding to a fixed length (after any prefix) - e.g. use INV-000123 instead of INV-123.
  • Should invoice and credit notes share a sequence or have their own sequence?

To configure your own settings, go to SettingsOrder/invoice settings and click on the Number sequences tab.

From here, you can manage your sequences. You have the option to create multiple sequences for the same document type, for example, multiple different invoice number sequences. If you choose to do this, you will need to ensure you have set your default sequence for new invoices/credit note, which can be done at the bottom of the first tab (Sales order & invoice settings) on that same page. If you have multiple possible sequences for invoice numbers, you will be prompted when creating an invoice to set which sequence to use, so you can choose to override the default if you need to.

In addition, if you have any sales integrations (ecommerce/POS), then in the settings for these integrations, you can choose to let them use your account-wide default, or to use a different sequence. This is ideal if, for example, you’d like your webshop orders to use a different prefix to your trade orders.

Frequently asked questions

How do I set my first invoice number?

If you’re new to Breww, you may need to set your first invoice/credit note number to “follow on” from the numbers that you were using before switching to Breww. This can easily be done by editing the sequence and setting the “Next number” box to the number that you’d like next. We have a separate guide on how to do this at How to change my starting invoice/credit note number.

Why is there an invoice/credit note prefix option in the accounting integration settings too?

Firstly, it’s important to note that these options in the accounting integration settings provide an additional prefix to any prefix set in the main Number Sequences settings. We recommend leaving the accounting integration prefixes blank and setting prefixes in the Number Sequences section. This will ensure that the invoice number in Breww matches the invoice number in your accounting software.

There are, however, some situations where a different number is required (such as to avoid conflicts with legacy platforms), which is why this option exists. As an example, if you set your prefix in Number Sequences to INV- and in accounting integrations to DOC-, then an invoice that shows in Breww as INV-123 would be uploaded to your accounting integration as DOC-INV-123.

Great improvement.
I noticed that only characters are allowed in the prefix, not numbers.
So prefix C24/I24 (change the prefix each year) is not possible.

Hi Gerard, Thanks for your comment and feedback! Yes, that’s right; the prefix can only contain letters, as well as some additional characters such as a hyphen, a forward slash, and an underscore. Cheers, Ben.
