Recurring billing for subscription

Hi Gautam,

Before building with Knit Pay Pro, I’d like to confirm one specific point about the SumUp + Paid Memberships Pro (PMPro) integration.

We need automated recurring billing: the system should automatically charge the member’s saved SumUp card on each renewal date, with no action required from the member. I saw in your support comments that for some gateways (e.g. Razorpay), Knit Pay currently only supports an “expiring subscription” model, where the customer has to manually renew and pay again.

Could you confirm specifically for SumUp + PMPro:

1. Does Knit Pay Pro automatically charge the member’s saved SumUp card on each renewal date, without the member logging in or paying manually?
2. If a renewal charge fails, does Knit Pay Pro retry automatically, and does it notify PMPro so the membership status updates accordingly (e.g. paused, cancelled)?
3. For these automatic renewal charges, where the cardholder is not present, are they sent to SumUp as merchant-initiated transactions using the stored mandate, so the member does not have to complete 3-D Secure again each time?

If not (as I expect…), would you build this as a paid service?

We’re building a membership platform for a nonprofit association in Austria, so reliable, fully automated billing is essential for us and we are definitely working with SumUp and not one of the larger payment providers.

Thank you very much for your help!

Best regards,
Lisa
