We previously required firms upgrading to CSV to purchase a year of maintenance on any product with prorated maintenance set to expire within 60 days of their order. We no longer do. However, we still highly recommend purchasing maintenance in this circumstance. Purchasing maintenance with new Server Software and new Client Server Versions of Tabs3 and PracticeMaster is still mandatory for the first year. Our Sales Team can always provide you with pricing and prorated expiration dates.
