Ultimate Edition

The Ultimate Edition builds on the features of the Essentials Edition and the Advanced Edition to give the aspiring and growing business the edge it needs to succeed over the competition. The best solution for larger businesses and those with true ambition for their business, the Synergy Accounts Ultimate Edition is designed to work with Microsoft SQL Server and includes every standard module and five or ten concurrent user licenses as standard.


Synergy Accounts Ultimate Edition is the perfect solution for the larger business and those that are really going places and want the ultimate solution to their accounting and business management needs!  The Ultimate edition is designed to use Microsoft SQL Server (both the Express Edition (maximum 5 concurrent users) and Full Editions supported, SQL Server 2008 and higher supported, SQL Server 2012 recommended) as the back end database and adds things like the Custom Fields Designer, Report Designer, and Time Recording modules to the features in the Advance Edition.

The Ultimate Edition can be used with the standard database, but for multi-user environments Microsoft SQL Server is a prerequisite for the best in speed and security.
