Crater is an invoicing solution, but not really a payment gateway service. It makes sense to use Crater to generate invoices. But, this can be used as accounting software for Bahmni Lite in the backend. Paytm and Cashfree have a unique feature called Payment links. These links can be generated and sent to the customers who use it for payment.

Crater has APIs for creating customer accounts and generating invoices. Staff in the hospital can fill a form and the Bahmni Lite backend could

Comparison between Paytm and Cashfree
Both Paytm and Cashfree have almost equal charges levied on different types of payment types. Both have good documentation and tutorials on how to implement the gateway to the apps and how to customize if needed. Both are similar in most of the cases.
