How does Open Datacheck work?

The manufacturer delivers his product master data including images and documents to Open Datacheck. These are examined by a powerful examination tool according to the respective industry quality guideline and the test results are transmitted to the manufacturer in a comprehensible manner. The manufacturer can then carry out the corresponding optimizations. The Datacheck service team only carries out final visual checks when the manufacturer has released the data, after which it is released to the wholesale trade. The processes can also be optimized by directly connecting PIM systems.
