Back in the day, it was only Paul who could change that. I asked him.
I agree with The Jester. We have our own designed Invoices, Statements and Windows Cleaned tickets. What ever is on George as a business name is irrelevant in our case.
When Paul was building George, Invoices were never part of the early program. Expenses weren't either. So we did our own on Excel.
I also didn't like the format of Invoices and expenses when it was later added, so we just stayed with what we had.
