StarkPay’s RaaS simplifies subscription-based payments by handling recurring transactions automatically. Applications only need to create a subscription plan in their StarkPay dashboard, and once a user subscribes, reccuring payments are processed - no further action required from either the user or the business.

With StarkPay, businesses can offer a frictionless and reliable subscription experience without worrying about payment management.
