How does my client cancel a payment?

Thanks for visiting us here, @ljpdesign65.

I'll help get your customer cancel the  payment. You'll have to void the transaction to cancel a payment. QuickBooks Payments allows you to process refunds within six months from the date of sale. After this period, you can provide a refund using cash or check. Let me guide you how.

To void and fully refund a transaction:

1. Sign in to your QuickBooks Payments account.
2. From the Processing Tools drop-down, go to Reverse Transaction.
3. Fill out the necessary fields and select Search.
4. Choose the transaction you want to refund, click Submit.

Refer to this guide for more information: Void or refund transactions in QuickBooks Payments.

I'm also attaching this link here in case you need help with other payments-related tasks. It has topics with articles and videos to guide you along: QuickBooks Payments.
