The Syntec index reflects the evolution of salary costs (mainly intellectual services) of companies in the professional branches of the Syntec Federation:
- “Syntec Informatique“,
- “Syntec Ingénierie“,
- “Groupement Syntec des Syndicats d’Études et de Conseil“.
It is mainly used to update the financial clauses of engineering, contracted personnel, maintenance, and IT contracts. Its value is calculated each month based on a survey of representative companies.
The Ministry of Economics and Finance in France has recognized the Syntec index since September 11, 1974.
