Easy way to setup payment gateway for website.

Hi there, @salmanbhay.

As suggested by Fiat above, we need to utilize a third-party app for a payment processor. Since we're unable to use QB payment in your case.

If you may want to visit our QuickBooks Apps Center to find an application in the Search bar. Enter the keyword or the app name then you'll see the available apps that can integrate QuickBooks Online.

You can also visit the app center within your account. 

Here's how:

1. Sign in to QuickBooks Online.
2. On the left pane, click the Apps tab.
3. Enter the hint word for the specific app.
4. To search, click the Magnifying glass.

Alternatively, here are the list of articles that may help you with the most commonly asked questions, you can check out this resource: QuickBooks Payments FAQ.
