A. The maintenance group is charged to follow whether the clients are receiving detailed maintenance estimation 60 days before the expiration of their maintenance contract. It sends also estimation for each new software order in the 15 days following the delivery. The persons charged with the maintenance have also to answer to the price questions, to explain the multiple advantages which an active maintenance contract provides to the clients of IGE SA, and to resolve the different problems which are taken from the Clients service. However, its task does not consist neither to ensure a technical support nor to issue licence codes. Each group agency has a maintenance service.
