With billwerk, you can seamlessly automate your recurring business model with Reepay Payment's integrated payment gateway. Contract creation, contract renewals, upgrades and downgrades, invoices, payments and open receivables - the combination of billwerk and Reepay allows you to do it all with one provider and one point of contact.

Various acquirers are already connected via the Reepay Payment Gateway and can be selected. The gateway handles complex setups and a very high transaction volume and can thus be used easily and securely by small and medium-sized enterprises as well as large enterprises. Currently, the payment methods credit card and Apple Pay are available.

  • Acquirer independence

    Choose between all acquirers supported by Reepay Payment.

  • Intelligent routing

    Based on this, you can minimize acquirer costs, as intelligent routing selects your most favorably priced connected acquirer in each case. In addition, if an acquirer fails, you can quickly switch to another provider.
