GEAC, the troubled Canadian enterprise resource planning software specialist, is to shed 100 jobs and close two of its 10 UK offices.
Nick Williams, chairman of the User Group for Geac's System21 ERP software, said: "There is a concern that service might slip, but the assurances that we have had so far from Geac are that it is focusing more on customers. It is a bit too early to say what impact this restructuring will have."
Paul Hill, financial controller at System21 user Katsouris Fresh Foods, added: "I do expect to see a full briefing to find out how it affects end-users."
Geac has been hit by declining demand for ERP software and services, just over a year after buying ERP specialist JBA for £92m.
Chris Allen, managing director of Geac, said: "The traditional sectors that we were strong in are the ones that are now declining. We don't anticipate this affecting users negatively. It is very sad for me to have this happening, but we do have a change in the market at the moment."
