Where more than one computer needs to have access to Tally.ERP 9, a Gold edition is what you need. Any number of users can simultaneously have read and write access.
Like with Silver you can manage as many companies (business entities) and personal books of accounts as you need. You may also create as many users as you need, and provide each with the appropriate level of security.
With Remote Access, you can authorize access to your Chartered Accountants, who with their Tally.ERP 9 - Auditors' Edition, can remotely provide audit, compliance and advisory services.
Similarly your Tally Service Partners can, via Remote Access, answers your queries and provide support.
As a Gold user, you can create ten TSS identities, with which your mobile users can login to your system from home or while on the move. Other users of Tally.ERP 9 can also grant access to you by authorizing these TSS identities.
It is easy to migrate to Gold from Silver - contact your Tally Partner. Your license will get updated to Gold and you can now access Tally.ERP 9 from multiple systems without the need to make any other change!
