Thanks for these replies.  Let me try to clarify the fact pattern first.

As an example, assume I have a $500 deposit to a bank account that's connected to our QBO account.

The $500 transaction represents (i) a $50 sale of an inventory item that has been separately captured in QBO via a Stripe integration and (ii) multiple (let's say 9) other non-inventory revenue items (and some processing fees) that have been credited/debited to the bank account.

Ordinarily I would start by "Matching" the inventory sale amount deposited to the Stripe transaction, then click "Resolve Difference" to add the processing fee for that transaction.  You can add more lines for additional "resolving" transactions, but QBO apparently only allows you to have 5 "resolving transactions" and I need more than 5 (a total of 9 in my example) to completely account for this one bank deposit.

In another Community thread I found today, in mid-2021 a QBO user complained about the limit of 5 resolving transactions and others agreed that would be a useful improvement.  But apparently nothing has been done about it.

Mich_S's proposed solution sounds potentially helpful, but I don't fully understand it.  Are you suggesting that I create a new bank deposit for $50 and match that to the $50 inventory sale?  If that somehow left me with only a $450 balance on the initial $500 deposit, I could "Split" it and enter 9 different categorized items to account for it.  But I don't see how creating and matching the separate $50 transaction would reduce the deposit amount balance shown in QBO from $500 to $450.  If this is in fact a solution to my problem above, please help me understand the steps better.

Finally, based on my additional explanation of the fact pattern, perhaps there's a different QBO solution/workaround out there?

Thank you.
