@Sg_Papa have you tried
- creating a bank account for your credit card in Manager
- bank import your credit card statement
- bank rules for your repeat transactions
- inter account transfer for your credit card payment
Combining work and personal expenses in one account dramatically increases your bookkeeping work. Transactions must be classified as work or personal and the most efficient time to do this is when you make a purchase. Doing it later when going through your bank import is possible but it is slower and less accurate.
The alternative is manually entering the few credit card business transactions you do.
