Matching payments doesn't appear to be related to a current Ascora issue, Katrina. I'll share more details on why you're unable to match transactions in QuickBooks Online (QBO).
When utilizing the Find match option on the QuickBooks banking page, some transactions are unable to find their match from existing records because of the following:
- The amounts or dates don’t match.
- The transaction is older than 6 months.
- The bank account associated with the payment isn't the same as the bank where the match is located.
- The payment has been reconciled.
- The record is already matched to another transaction.
