PO number formatting
Set a prefix, year, and starting number for purchase orders; lock the format to prevent accidental changes.
PO number formatting
PO numbers in PO Flow follow a configurable pattern of prefix-year-sequence, for example PO-2026-0001.
Configuration
Go to Settings and scroll to Purchase Order Numbering. The fields are:
- Prefix — letters or characters at the start. Defaults to PO.
- Year — the year segment, free text so you can use 2026, FY26, or anything else.
- Starting number — the sequence to start counting from for new POs.
- Lock numbering — when on, the prefix and year cannot be edited from individual POs.
Returns to Supplier (RTS) numbering
RTS documents use the same scheme in the Return to Supplier Numbering section, with their own prefix (defaults to RTS), year, and starting number.
Editing a PO number directly
If Lock numbering is off, you can edit the PO number on the PO form itself. Each PO number must be unique within your shop.
