WebSYNCRO service is intended for suppliers delivering parts in sequence directly to an assembly line. It provides users with an outline on JIS call-offs that are sent and received via EDI servers. A user works with the application using the Internet browsers.

The application serves the purpose of one alternate source of information for suppliers during EDI communication failure between Škoda Auto and a supplier.

The purpose of the application rests in displaying JIS call-offs with optional filtering, printing, and downloading of displayed call-offs.
