When I categorize an expense in bank transactions it then changes all the others in the bank transaction list to the same thing, why? How do I get it to stop doing this?

Hello cjones1915,

Welcome to Community!  QuickBooks Online provides the option to set up bank rules, so you can categorize and match your transactions effortlessly.  Each bank rule allows you to select the option to 'Automatically confirm transactions this rule applies to'.  Having additional transactions automatically categorized can impact your work. I would be happy to help!

QuickBooks Online provides additional options for your bank feed.  You can set your preferences accordingly.  In your situation I recommend disabling 'Enable suggested categorization'.  Here's how;

1. Open Transactions, then Bank transactions from the left menu
2. Select the tile for the account
3. Click on the small  ⚙ above the Action column
4. Remove the checkmark beside Enable suggested categorization
That should do it!

If you experience the same result, please don't hesitate to contact us outside of Community. We'd love the opportunity to work with you in real-time, and ensure you're able to accomplish your banking goals as soon as possible!

Feel free to reach out again, if you have other questions.  We would be glad to assist!
