SlimPay – Specialist for Subscription Payment in Europe

The American subscription market is years ahead of the German – in Europe there is still plenty room for growth, but here, too, the industry is growing steadily and strongly. SlimPay is one of our partners we have integrated into the billwerk platform for payment processing – and the one whose core business is in the European payments area.

Furthermore, billwerk – as a German company like ourselves – understands German data protection requirements.
