Since we’re the payments provider (using Stripe under the hood), we’re not currently able to support “bring your own provider” unfortunately.
They use Clover’s platform to provide devices and APIs (you could in theory use another vendor’s devices if you really wanted to).
In general, I don’t want someone else to be my payments provider since we do a lot of subscriptions, which would leave me completely locked in to a provider. Already been there done that with PayPal.
For folks who just want to get set up and get going quickly and don't mind working with a payfac to do so, we feel they should have more options, especially when it comes to DX.
I want to have a consistent developer experience and a flexible platform regardless of which payment provider I'm using. I might also be offering a service to other people who want to "plug in" their own choice of payment providers.
Right now, I have to build all the subscription stuff myself.
