How to Create Security Control Users & Manage Permissions in Tally Prime

July 24, 202611 min readAkib Husain

Enforcing user access control in Tally Prime is a fundamental requirement for internal financial control and MCA Audit Trail compliance. Setting up individual Security Control Users allows company administrators to assign specific roles (Data Entry, Auditor, Accountant) and restrict unauthorized voucher or report access.

Quick Answer: How to Setup Security Control Users in Tally Prime?

TrulyInvoice connects securely to Tally Prime via the local Port 9000 XML-RPC gateway. Tally Prime's Security Control feature allows administrators to define custom user roles (e.g. Purchase Data Entry, Auditor, Accountant) and restrict permissions for backdated purchase vouchers, master alterations, and sensitive financial reports.

  • Enable Administrator: Alt+K (Company) > Alter > Set 'Control User Access' = Yes.
  • Create User Roles: Alt+K > User Management > User Roles (Set Disallow/Allow permissions).
  • Assign Credentials: Alt+K > User Management > Users and Passwords.
  • TrulyInvoice authenticates via local Port 9000 to post clean purchase vouchers.

Step-by-Step SOP: Setting Up Security & Roles

  1. Enable Administrator Control: Press Alt+K (Company) > Alter. Set Control User Access to Company Data = Yes. Define Admin credentials.
  2. Define Custom User Roles: Go to Alt+K > User Management > User Roles. Create roles (e.g. Purchase Clerk or Auditor). Set Disallow rules for backdated entries or report printing.
  3. Assign Passwords: Go to Alt+K > User Management > Users and Passwords. Add employee usernames and select their respective roles.
