Managing Multiple Companies with One HRMS
A multi-company HRMS must give a group one operating platform without allowing one subsidiary to see or change another subsidiary’s protected employee data.
Model the organization hierarchy
Represent the parent company and each subsidiary as explicit entities with stable identifiers. Employees, departments, locations, policies and documents should belong to the correct company rather than relying on a display name.
Separate data and access
- Resolve every request to an authenticated tenant and permitted company scope.
- Never trust a company identifier supplied only by the browser.
- Apply row-level company filters in backend services, exports and search.
- Allow group HR access only through explicit permissions.
- Record cross-company actions in an audit log.
Support local control with group standards
Company configuration
Maintain local holidays, locations, policies, documents and approval chains.
Shared templates
Let group HR distribute standard policies or documents with controlled copying.
Employee assignment
Associate employees with a primary company and permitted secondary relationships.
Consolidated reporting
Aggregate authorized metrics while preserving drill-down security.
Subscription enforcement
Enable modules and user limits at the client level across its company hierarchy.
Design permissions by scope
A role is incomplete without scope. ‘View employees’ should specify self, team, company, selected companies or all authorized subsidiaries. The same rule must protect pages, APIs, exports and mobile apps.
Avoid common implementation mistakes
- Returning every company and filtering only in the frontend.
- Using company names instead of immutable IDs.
- Mixing tenant configuration with employee operational data.
- Giving subsidiary admins group-wide reporting by default.
- Copying policies without version or source history.
