Tally.ERP 9 is presently available in two editions: Silver & Gold.
Silver is for a single user, while Gold is for unlimited users on a Local Area Network (LAN).
What other differences exist between editions? None, all capabilities and features will be available in every edition. The only reason to choose between editions is the number of systems from which Tally.ERP 9 can be accessed.
A 'user' in this context is actually a computer system. We do not complicate your purchase decision with 'concurrent user', 'named user' and so on.
Therefore, Tally.ERP 9 Silver can be activated (as in licensed) on one computer and used from that same computer. Tally.ERP 9 Gold can be activated on one computer and accessed from any or all computers on that network.
Maintaining our philosophy - Power of Simplicity ® - you only need to choose an option that suits your needs.
If you decide to buy a Silver edition, you can migrate to Gold anytime. And with a Gold, as users increase, there is no need to come back to us for additional user licensing. You simply avoid the commercial, purchase & administrative complications of these changes.
