Hi @Lobi-Business Welcome in
hmm... Yup of course,
But, due to the fact that funnelish itself is using the Backpack and the App in order to show it's capabilities and of course to increase trust, it requires you to do that manually, (ie. contacting support, and then asking them to cancel your current billing account, and then start a new billing account without your apps account being affected).
Huh! Yeah! Isn't that obvious
Yup! they can use either Paypal or a Credit Card through Stripe, and even in many cases when Stripe fails to capture a payment for some dumb reason, your customers still have the option to use Paypal which virtually never fails... and of course they can checkout using a Credit/Debit card through Paypal as well, either through their accounts or without having a Paypal account but still doing so through Paypal...
PS. The dev team is working hard on getting more payment methods supported asap, so you'll have far more options in Q1 next year.
Feel free to reply/or start a new thread if you have any more questions or concerns or ideas
