Netting AR against AP in QBO

Hi friends,

I'm a long time accountant but new to QBO. We have a customer who is also a vendor. They are set up as both in QBO. Management wants to net the two together and make one transaction to clear them against each other. I'm sure there is a way to do it, but I'd like it to be as clean as possible and leave a good audit trail. Does anyone have a good approach! Merci!
