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.
