How many days does it take for a check to clear the invoice says paid but it says it’s reviewing payment and I can’t find a way to track it

Hi, rksframing. Let me share some information on how and when QuickBooks deposits customer payments.

If you're new to QuickBooks Payments, we'll deposit your first set of payments within 5 business days and will remain in Review status. These early deposits take a bit longer while we set up your account. Once we set up everything, we'll deposit customer payments much faster, depending on your deposit speed.

Payments processed before 3:00 p.m. PST will be deposited into your bank account on the following business day. In contrast, payments received after 3:00 p.m. PST will be deposited within two business days.

Should you want to track  the payment, follow  these steps:

1. In your QBO account, select Sales.
2. Go to Deposits then select the deposit. 

I'll also include this article to learn more about this process: Find Out When QuickBooks Payments Deposits Your Money.

Furthermore, feel free to visit this additional resource to learn more on recording invoice payments in QuickBooks Online.

I'll be on the lookout in the comment section if you have more questions about payments and other QuickBooks-related matters. Have a wonderful day.
