Summary

Machine-generated summary

A Swiss public tender seeks a provider for the complete redevelopment of the sedex Message Client (sM-Client), a middleware application developed on behalf of the Swiss Tax Conference (SSK) and the Federal Social Insurance Office (BSV) for exchanging sedex messages according to standard eCH-0058, in productive use by over 150 participants for more than 15 years. Services include initial development as a general contractor (specifications, architecture, documentation, testing, training) plus maintenance and support over 4 years, with 2 x 2-year extension options.

Support für die Erstinstallation. Der Anbieter hat auch sämtliche als Optionen bezeichneten Anforderungen (insbesondere die Verlängerungsoptionen für Wartung/Support) zu offerieren.
