Answer 1)For Purchase Orders to the same supplier we recommend adding the new goods to the previous Purchase Order. If you want to create a separate PO for the same supplier on the same day, you could add a number, letter or word to the end of the PO reference number to avoid any confusion.

Answer DAISY2)The last two PO numbers are generated randomly and go from 1-99 so unfortunately they could easily repeat. This is the way the system is designed, but if you would like suggest to the developers that this should be changed please feel free to start a new topic on Linnworks.net forums .

Every PO should have a unique number to avoid confusion when booking goods in and paying supplier invoices.
