A customer is having issues paying the online invoices. They keep on getting the error "Payment wasn’t successful. Try again or contact your seller."

Hi accounting-richa,

Welcome the Community. It's essential that you receive payments for the products and services you provide to your customers. QuickBooks Online is a great program that gives you the ability to easily track your sales and expenses. I'd be glad to help.

This type of issue can be caused by browser cache and cookies as they can prevent the system from functioning effectively. I'd encourage your customer to refer to the following steps to complete some browser troubleshooting.
 

• Clear browser cache.
• Try in a private browser window.
• Use another browser type.
• Make sure you're using supported browsers.
• Turn off any ad and popup blockers temporarily.
   

If the steps provided above don't work, I recommend that you contact our customer support team. They'll be able to take a closer look at your account. Here are some options available to reach out to our team.

• Phone: Call us at 1-855-253-1536 from Monday to Friday between the hours of 9 AM and 8 PM EST.
• Schedule a Callback or start a Chat: click (?)Help in the upper right > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback or Start a Chat.
   

Let me know if you have questions, I'll be happy to help.
