To add a PO number prefix, follow the instructions below.
1. On the toolbar, click Settings.
2. On the Settings page, on the left sidebar, click Company Info.
3. On the Purchase Order Settings section at the bottom, enter your preferred PO Number Prefix. For example, if you put skubana as the prefix, skubana will be added to the PO number every time a PO is generated. Thus, your first PO number will read as skubana1000, instead of just 1000, which would be the case if the PO number prefix remains blank.
4. Click Update.
