Hi there, @alva1.
QuickBooks Merchant Services doesn't have the feature that can verify a check during a process.
Although, we have preventive measures on how to avoid chargebacks.
One of them is to get the cardholder's signatures. Have them sign your cancelation or return policy on all orders. It's also very important to manage the customer’s expectations up-front. Document your efforts and work with your customers to resolve issues.
For more info on how to handle chargebacks and retrieval requests for QuickBooks Payments, check out this article: What is a chargeback and what to do if you get one.
If you have any follow-up questions or concerns, please get back to us. My QuickBooks Community Team and other users in this public forum are here to help you.
