Hi there, @MMM Consulting. Thank you for getting back to us.

To clarify, are you using Sync with Square app? If you do, make sure your tips are mapped properly. This way, they automatically match against the ones you have in QuickBooks. I recommend reaching out to their support for assistance.

Meanwhile, you may consider switching to the Connect to Square app to bring your sales transactions into QuickBooks. When they appear in QuickBooks, you can review and categorize them. Check out this article for more info: Connect your Square account to QBO.

Additionally, you can add tips to your payment forms in QBO. You can change its default account from your settings.

Visit us again if you have further questions about managing square transactions. The Community is always here to help. Have a wonderful day!
