Cannot process credit card payment in quickbook online sandbox company. It says "Payment not processed because of a problem on our end." How this problem can be resolved?

Hello there, @

You can resend those invoices to customers and let them pay using the new ones. Let me guide you how.

Here's how:

1. From the left panel, select Sales.
2. Click Customers.
3. Click the name of the affected customer, then go to Transaction Lists tab.
4. Locate and open that specific invoice(s).
5. Click Save and send at the bottom.

For more details, you can check this article: How to let my customer pay their invoice online.

I'll be around to help if you have any other QuickBooks questions. Have a good one.

Thanks for the reply.

But it is not customer, I am paying customer invoice from the company login via credit card. 

Thanks for the clarification, @sparkleptic.

I've also got you this article for reference when entering a delayed credit in QuickBooks Online (QBO): Enter and Apply a Credit Memo or Delayed Credit.

Seems like you did not understand my question.  I just simply want to ask you that can I test credit card payment in quickboooks online sandbox company? Yes or No. If yes, then what are the required settings.

I need an answer. Please don't try to divert the topic. I am not getting an answer to my query from anyone.

You all are trying to tell me to check other's post but you are not answering my query. This is really bad kind of support.

Hello @sparkleptic,

As much as we would like to address your concern about your QuickBooks Online Sandbox company and why you've been receiving an error message. But we have separate support who can better explain the components of processing your transactions in the Sandbox company.

That being said, here's how you can contact our dedicated support:

1. Go to the Intuit Developer Support homepage.
2. Tap QuickBooks Online.
3. Select Ask a Question.
4. Click Sign in.

Keep me posted in the comment section down below if you have any other questions about your regular QuickBooks Online account. I'll always be around, ready to help.

I followed this but unfortunately received the same response like you are giving.

I've read your first post, sparkleptic.

The error message occurs due to an invalid merchant configuration. In this case, I highly recommend contacting our QuickBooks Payments/Merchant Support Team, since we need to pull up your account information securely. They can check your Intuit Merchant ID and help configure it with more tools.

You can reach them through this link: Payments/Merchant Support.

As always, reach out to us if you have any other concerns in the future. We're here to help as much as we can.
