If you want to change from Stripe to another payment processor that's not Stripe you may only do so if your business is on their list of prohibited businesses.
You'll need to submit a ticket to do this and mention why you're not able to use Stripe anymore as your payment processor.
If you migrated to Cratejoy from another subscription business platform:
If you migrated from a different platform where you were running your subscription business before (e.g. Woocommerce) and you had Cratejoy migrate those existing subscriptions to your new Cratejoy account, then you'll need to submit a ticket if you want to change payment processors.
However, we highly recommend Stripe as they have more successful transaction rates than any other payment processor.
