We have a new bookkeeper/AP guy and he's asking for a bill numbering system similar to what you get with pretty much every other transaction in NetSuite. Now, I guess this sort of makes sense, but I'm not sure why it would be needful. My question is: Is this normal? Is this a common thing and I've just never come across it? I've never done A/P, but I have spent a lot of time handling vendor invoices throughout my life, and have never had a need for this. I've always just used the vendor bill number as my reference number for the transaction.
