Good evening, @c_shine. 

Thanks for reaching back out and letting us know you don't have a "Payment Link" option in your QuickBooks Online account. 

Once your conversation with support has ended, if the issue still hasn't been resolved, loop back around to us, and we'll dive further into this. 

I'll be right around the corner when you're ready. Hit the Reply button to post information if need be. Have a splendid day!
