Hello @Whittade,
I appreciate you for keeping in touch with us here in the Community about the issue when paying using your Bank of America (BOA) account. I've reviewed the thread from the top and was able to read your response to my initial post on this thread.
I would feel the same if I'm having a hard time figuring out who to contact or how to identify the cause of the payment rejection. Allow me to chime in and provide clarification about how you can resolve the problem with the payment.
Since the link shows an Intuit web address, your vendor is using our payment service. Yes, you're right. It's not an issue with your account, and you're only making a payment to the vendor via the link sent to you.
There's no way for you to determine the cause of the rejection by yourself. You'll need to inform the vendor so they can check on their account if the details of the first attempt of paying the invoice are showing.
You're a customer of your vendor and they're sending an invoice for you to pay. If the rejection details are unavailable on their account or there are no details about the error (from the attempt of paying using BOA), have them contact the dedicated support team.
If your vendor is using our Merchant Service, the correct support is QuickBooks Payments. They can review the payment transactions, like the logs from the failed attempt to successful payment: Contact QuickBooks products and services Support.
Also, you mentioned there's no problem with your BOM account. I recommend you review your bank details and make sure you're entering the correct information.
The details you enter should be the exact bank account and routing number. For the bank type, you'll need to verify it with your financial institution if it's a Business Checking account.
To track business expenses, you can use the Bill and Bill Payment functions. For more details about the process, visit this article: Enter bills and record bill payments in QuickBooks Online.
Get back to me if you have additional questions about processing the payment. I'll be sure to assist you in this public space. Have a great day.
