I hope you're having a great week so far. You can add business expenses from your receipt captures in the receipt tab. Just navigate to the For Review tab and select to Review, Add, or Match the expenses.
I also suggest reaching out to your accountant to figure out what account you need to "credit." They'll can tell you what account to choose for the transaction, so your books are correct.
I'm only a hop, skip, and jump away if you have any other questions. Enjoy the rest of your week!
