Custom purchase order numbering

This article covers the options you have for customizing your purchase order numbering format.

The default format is a combination of year and a running number, for example, 2021-0001. The prefix (year) can be changed under Settings --> Purchase order setup --> PO number.

Prefix type options

You can choose between the following prefixes:

Year - The default format, combination of year and running number, e.g "2021-0001"

Custom - Custom text (up to 16 characters) and running number, e.g. "Customtext - 0001"

Blank - Only runnning number e.g. "0001"

Budget - Budget number and running number per budget, e.g. if you have set up a budget "48001 - My first budget", the PO format will be "48001-0001". If the next PO is created on another budget (for example on budget 48002 - My second budget), the PO number for this will be 48002-0001.

You can also select a starting number from which the running number will start.
