Software as individual as you are


Many customers use ERP systems such as SAP. ERP systems can be connected to 4-check to prevent media disruptions and speed up processes.


4-check is hosted in a German data center in Frankfurt. If you have the specifications to use other servers, we can discuss this individually.


Single sign-on, i.e. the one-time registration of your employees in your IT network, enables a quick use of the system. Together we can also integrate 4-check.


Our open API interface (REST) enables automated data exchange. Our Swagger documentation helps you to link your own applications.


Our complete API interface is documented in a detailed Swagger documentation. This is openly visible to guarantee the best possible work.


Software must meet the requirements of its users. For this reason we also offer individual programming. Just contact us for this.
