A: Hi truefriend, 👋

Stripe is already integrated: https://invoiless.com/partners/stripe, please refer to this documentation to learn more: https://invoiless.tawk.help/article/how-to-connect-my-stripe-account

We are working to add PayPal and Razorpay, they will be available very soon, for Wise and Mercury are not on our product roadmap at the moment.
