Adding MPN to invoice

[maxboa_79]

Hello, is there a way to add MPN from each listing to the invoice/packing slip as when I'm packing orders for my workplace I have to go onto each individual ebay listing and write down each part number on the corresponding invoice which could be made easier if I could add the MPN directly onto it

Try the "Print invoices and more", tab, then "Invoice/Packing slip" and "Customise".

Thanks for your reply, I've tried that but can't see an option for MPN unfortunately

You may have to copy and paste the MPN into the invoice
