Hi there, @dhavalkakadiya. I've got your back, and I'll share some details about changing the payment method on your sales receipt in QuickBooks Point of Sales.

Please be aware that the option to change the payment method on your existing sales receipts is unavailable. As a workaround, you can reverse a sales receipt and then re-enter the details, including the correct payment method. Before doing so, you'll want to secure a backup copy of your company file. If you wish to continue with this process, I'll input the steps below so you can proceed to reverse a sales receipt.

To begin, you'll need to disconnect your Intuit QuickBooks Payments account from the Point of Sale. This way, you'll be able to get through and reverse a sale. Here's how:

1. Go to File, then select Setup Interview.
2. Select the Payments tab.
3. Choose No to Would you like to accept Credit and Debit Cards?.
4. Click Done.

You'll then proceed to make or reverse a sale. These are the steps:

1. From the Make a Sale screen, select the item for return. It should be identical to the original credit card sale.
2. Select Return Item.
3. Select Credit as the payment method.
4. Select Refund, then choose the card type.
5. Select Save Only or Save & Print.

Once done, reconnect your Intuit QuickBooks Payments account to Point of Sale. Here's how:

1. From the File menu, select Setup Interview.
2. Select the Payments tab.
3. Select Yes to Would you like to accept Credit and Debit Cards?, then select Sign In.
4. Enter your Intuit Merchant Services login and password.
5. Choose the Merchant Account you want to use, then select OK.
6. Select Done.
