Great question!  for Home Depot and Lowes, we recommend you use the credit card module (4-7) and enter each receipt separately.  What's great about this is that you can reconcile credit cards like a bank statement AND make partial payments against a running balance without having entered the statement.  But if you choose to continue using regular AP then enter each receipt separately also so you can identify the proper job.  Although credit card payments are due when they are due, and not when you get paid so it isn't typically required that they be on an open AP invoice list by job.  I hope this helps!
