Sage 500 was historically sold as a perpetually licensed product. Existing customers may still buy modules and pay the optional, annual maintenance and support plan. New customers may subscribe to Sage 500 with prices comparable to that of similar products including NetSuite, and Microsoft Dynamics GP. Pricing is slightly higher than Sage 100 c. Implementation costs are typically 50% more than the original software purchase or double the first year subscription cost (e.g., a $30,000 SLP purchase will cost about $45,000 to implement and a $20,000 subscription will cost about $40,000 to implement).
