In my quick book account , payment link tab is not showing even in the setting option is not coming can someone help me out

Greetings! 

Thanks for coming to the Community for your concerns. Currently, the Payment service option is available only to the United States and Canada versions of QuickBooks Online.

Rest assured that I will make every effort to stay on top of your request and will work closely with our Development team to ensure the availability of this feature for our international users.

In the meantime, while our product developers are reviewing this feature, I suggest exploring third-party apps that can help facilitate online payment processing. You'll want to visit our App Center or in the Apps menu to find a third-party provider that can manage electronic payments for online invoices and in-person transactions.

1. Select Apps from the sidebar menu.
2. Click the Find Apps tab.
3. Type a keyword in the search bar or choose Browse Categories to filter the results.

This information helps you find the right app to integrate into your QuickBooks Online account. If you have any questions or concerns, please let me know, and I'll be happy to assist you further. Have a great day!

You can use a 3rd party solution to accept payments and integrate it with QBO.
