billwerk Testimonials

"From the beginning we liked that billwerk is an open platform with a very well documented API. In addition, we received competent advice and the willingness to respond to our partly special requirements."

"When analyzing different subscription management systems, it was important to us to find a company that had a GoBD certificate for accounting consolidating legacy systems, and billwerk was the only company we found. Thanks to this consolidating accounting in billwerk, we can completely avoid mapping the business models in our group ERP."
