We also sell B2B, and businesses that receive product from us want THEIR item number listed on the packing slip. It would be great to have space to add that. It would also be nice to have a separate UPC field that could be added, so that both the SKU and the UPC would show, rather than an either or situation like we have now. Right now we are printing special packing slips for our B2B shipments because there is no way for both the SKU and UPC to show on a ShippingEasy packing slip, let alone any unique info.
Final thought is to add a unit of measure - though we just convert right now. If someone orders 1 case, we have our website set up to convert it to 24 units before sending to ShippingEasy, so this is less of a need and more of a suggestion.
