I have submitted all my documents , I still have the resolution center holidng my case yet I call and they say oh your good to go. yet my invoice is still not being paid.

I appreciate what you've done so far and recognize how important it is to receive the payment from your customer, 729bengruenberg. Let's work together to resolve this so your customer can pay your invoice.

There are several reasons for customer payments getting declined, including the following:
 

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

You can also check out this article for more details: Fix customer's declined credit card payments.

However, if all the provided information is accurate but the card is still declined, I suggest advising your customer to contact their bank directly.

I also suggest reaching out again with our Support team so they can securely check your account and investigate the issue further. They can also create a ticket for investigation if necessary.

Additionally, you can check out this article for more details on recording invoice payments in QuickBooks: Receive and process payments in QuickBooks Online with QuickBooks Payments.
