Duplicates on bank statements tagging

I think you should read some of the getting started guides as it sounds like you’ve missed most of them.

Bank feeds would be the most sensible option if you do the other things the “right” way. For instance, card payments would usually be tagged to a separate credit card account, or if via Stripe from the Stripe account.

Have a read of some articles in the knowledge base before doing anything else.

What a lot of people try and do is start using Quickfile like they used their old system (even if it was old bits of paper and memory!) but you need to start again rather than trying to go against the grain with it.
