Hi there,
Payments being disappointed can indicate they were either cancelled or on hold. I'm here to provide you more information and guide how you can address this. Also, if you mean by anything else please let us know.
First, you'll need to ensure that you customer has successfully paid you through QBO Payments. Ask them if the transaction went successfully without any problems through the third-party payment service they used. If it was successful, your payments are being processed to deposit into your bank account. If you're new to QuickBooks Payments, we'll deposit your first set of payments within 5 business days. These early deposits take longer while we set up your account. After that, you'll receive your customer payments much faster depending on your deposit speed.
If the payment from your customer didn't successfully went through the third-party payment service integrated to QuickBooks Payments, you can consider doing the payments outside QBO and record the payment manually.
If the payments from your customer should supposedly appear to your Undeposited Funds before your bank account and is now missing, consider checking out this article: Find missing payments you want to deposit in the Bank Deposit window in QuickBooks Online.
Additionally, you can also contact out QuickBooks Payment support if you have concerns that needs to be addressed privately especially when dealing with your QB Payment account concerns.
Moreover, you can also consider voiding or refunding a customer payment in QuickBooks Online if necessary.
Let me know if you have additional concerns besides payments missing from the For Review tab in QBO. We're always here to help.
