Thank you for getting back to us here on the Community page, @inkheadcreativewriting.
At this time, we can try switching the report's accounting method from Cash to Accrual or vice versa. This helps us check what causes the difference and review the transactions from cash or accrual.
If you're getting the same problem, let's compare your sales and the Profit and Loss report, then review each transaction and what is causing them not to match. If you need further assistance with checking your transactions, I suggest reaching out to our Support Team. To contact support, tap on Contact us from the Help menu.
Let me know if you have any other questions. I'm a few clicks away to help. Have a good day!
