My customers have not been able to pay me, I get emails from Quickbooks with "wants to pay youThey reviewed your invoice, but need more info.Reach out..." How do I fix?

I appreciate the details you've included in your post, better.

Let me make it up by explaining why your customers are unable to pay you in QuickBooks Online (QBO).

If you use QuickBooks Payments, you have to turn it on so that customers can pay directly from an invoice. 

Once the invoices are sent to your customers, they'll receive an email allowing them to review and pay the invoice by choosing Review and pay or Pay invoice. Depending on your settings, they can pay using a credit card or an ACH bank transfer.

There are times it doesn't go through due to common issues such as authorization problems or missing information.

Here are a few reasons why credit card payments have been declined:

• The info they entered may not match what the bank has on the file.
• The payment amount might be larger than the limit set by the card issuer or bank. 

However, you can have your customer check with their bank to see if there are no restrictions that would cause the issue.

Moreover, here's a resource you can browse through for additional tips on how to help your customers if they can't pay for an invoice you sent:  What to do if your customers can't pay their invoices online.

Furthermore, I've also added this resource for you to be able to learn what to do if customers' credit card payments get declined when you process them: Fix customer's declined credit card payments.

If you still have further queries managing payments or anything else about QuickBooks, feel free to let me know. I'd be glad to assist you at any time. Stay safe, and have a good one.
