We pay suppliers and we issue them a remittance advise for the payment that tells them what invoices we are paying.

It turns out that NetSuite does NOT include Credit Notes on the detail, but does reduce the amount paid.

So the supplier payment is correct, but they have no knowledge of what credit notes we are applying.

What do other users do?

We have NetSuite telling us that NetSuite fundamentally can NOT do this action.

I find that very very difficult to believe!

Have you paid for customisation? As 1 developer told us NetSuite can do it but we need to pay extra for it!
