Welcome to the Community, @hifimikerva. I understand the need to process credit card payments for your customers.
There are a few common reasons why cards declined when processing payments.
- 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.
Since your client already contacted their bank, that should process the payment seamlessly. I'd recommend reprocessing the payment after an hour or two.
Additionally, you'll want to process customer payments directly from QuickBooks by signing up for QuickBooks Payments so you can send invoices to your customers from QuickBooks Online and pay you online.
You can also take and process payments in QuickBooks Online.
I'm always around here to be your guide if you have any additional or other concerns. Take care!
