I have triple checked all of my transactions, and exported my statement using OFX. However, the balance in my checking account isn’t matching to the balance shown in CB at the top of today’s date. Is there a way I can manually change that?
There isn’t a good way to change your bank import file, nor should you.
If you need to just change your daily balance you can click on the balance on the day you want to change and a balance adjustment dialog will appear, which will create a “Balance correction entry” bringing your end-of-day balance to whatever you enter.
