Maintenance & support for our products

All product licenses include Maintenance Package for the first year. You are recommended to re-order Maintenance Package before the expiry date. If you re-order Maintenance Package after the expiry date, that expiry date will be considered as the start date of the reordered Maintenance Package. Maintenance Package includes one year of upgrades to all new releases and fixes of the product, and email based support. For those needing more help we offer professional services.

Prosys has provided us software experts and tools with a long-term commitment. In our projects specification work is very important, yet it is difficult to get all requirements and details written in advance. This challenge was addressed by using agile methods, which produced good results.
Another important factor was the demanding work required to achieve interoperability between different systems. Overall, I rate Prosys services as praiseworthy and professional.
