!MC5 from Bartsch Software is Windows software for managed file transfer and EDI. It supports OFTP and OFTP2 (common in the automotive industry), AS2, SFTP and FTP/S, as client and as server. The EDI module displays received messages in readable form, converts between EDIFACT, VDA, X12, XML and flat files, among others, and connects to ERP systems through a file-based API. Add-ons cover ENGDAT and ENGPART for exchanging CAD/CAM data, email, an HTTP client, printing of VDA 4994 labels, ZUGFeRD/Factur-X invoices and running as a Windows service.
Bartsch Software is based in Kiel, Germany. The website names no owner or parent company. You install !MC5 yourself on your own Windows systems; the software updates itself by downloading the latest version and required files. The business data you exchange therefore stays under your own control, and you decide where the server runs. For European organisations that want to run their EDI traffic themselves, this is an on-premises option from a German maker.
