In the bank feed I can see transaction where QBO says it has found match BUT does not allow to process as match

Hello tim24,

Thanks for posting in the Community. Are you trying to match the transactions via the Receipts tab or Bank transactions tab? 

The Receipt function is strictly meant for cash transactions that do not go through the bank. Matching transactions created by uploading a receipt is not a recommended practice. To correctly match a receipt, it's essential to create an expense or bill transaction for the receipt and then match it in the bank feed until it shows up. This process should be followed to maintain accurate records of your transactions. If you have any queries, feel free to let me know.

For bank transactions under the For Review tab, remember to categorize them before matching with a receipt. Use 'Add Attachment' to add the receipt to the expense or bill created from the bank feed.
