Hi and welcome to Just Answer! I'm happy to help with your Financial Software questions. Feel free to interject at any time if you need clarification.
Do you import your activity directly from your bank? Or do you manually enter your credit card information.
Ok, great. Just wanted to make sure I understand your question.
