I’ve used GB for MANY years now. I’ve always tracked my credit card purchases separately in a spreadsheet and then recorded payment in GB. I’m considering adding a CC account and tracking internally with GB. I don’t understand how the payment would work though. If I record the CC expenditures in envelopes within the CC Account and then deduct money from the appropriate envelope in my checking account won’t that double dip the expense?
I mark all my credit card expenses just as I do other expenses. E.g. if I pay €100 on groceries with my bank account it’s a transaction for that account and my “groceries” envelope and similar if I pay €100 on groceries with my credit card (groceries “envelope” and account “credit card”)
When it’s time to pay the credit card bill I “transfer” money from one account to my credit card account, e.g. if my credit card bill is €400 and due date 1.9.2025, I book it as an account transfer from “bank account” to “credit card”. Bank account will have €400 less and Credit Card will have €400 more.
This is the way it works best, but your credit card has to be set up as a “paid in full” card. If you set it up as a card carrying a balance, it becomes a debt and you’ll lose the ability to assign transactions to envelopes. It becomes much more difficult to use the card this way.
