You can prefix the purchase order so you can better indentify orders relating to different Business Units. 


Business Unit Settings

Head to Business > Settings and the Formatting area. 

Under the Purchase Order Number format you can add in a prefix


You can add the Project / Job code into the order number as well here. 

Division Prefix

You can also add a separate prefix per Division as well 

You can also set a Division prefix in Division Settings. 

Recognition Consideration

Our advice is to keep it simple. Avoid a Pre-fix of say PO because the OCR engine might struggle to differentiate between an O and a 0 (zero). Use prefixes that are easy to recognise and aren’t similar to a number.
