If there are items on your credit card that repeat every month, we have some suggestions on how to keep track of them in Dryrun.
Manually add them as repeating items that are due on the typical date that you pay them off/that the credit card is due.
Add as much or as little detail as you need for these entries.
Make a category called 'Credit Card' to help keep track of items that typically appear on the card.
You could instead make regular categories related to the type of expense you've charged to the card, and set them to be placeholder items with end-dates close to the bill date. Unless cash flow is a serious issue, this way is much less work and quite accurate, aside from the date of the actual payment may differ a bit month to month.
