I have come across some dumb crap in Quickbooks but I think this might be at the top of my dumb crap list. I have to enter change orders when we have a change on the job that requires more invoicing. I use estimates to do this and name it Change Order 1 or 2, etc. Now I have to get creative and come up with different names for my change orders even though they are for different customers. This annoys me. I want to invoice, not think up poetry. So I get to do Change Order 1, Change Order #1, CO#1, COrder#1, CO1.......you get the idea. Change it back! Not being able to reuse invoice numbers across different customers is super annoying. This is not how you make happy customers.
