I appreciate what you've done so far, @ExPtNEFL. Let me share some information on how the Accept Payment tab works in QuickBooks Online (QBO).
To process payments using the "Accept Payment" tab, you must have an active QuickBooks Payments account. Keep in mind that Intuit will only be able to accept your payments if you have linked your transactions to a QuickBooks payment account.
Furthermore, I have added these helpful articles to learn more about the terms, agreements, and answers to the most frequently asked questions regarding payment processing in QuickBooks.
Feel free to drop a comment below if you have any questions about managing your QuickBooks payments. I'm always available in the Community to assist you. Stay safe and have a wonderful day!
