We are looking for an experienced software development company only. Individual freelancers, beginners, and small temporary teams should not apply.

Create a complete database architecture for:
* Companies

* Reports
* Audit history
4. SaaS Architecture
Must support:
* Multi-company accounts
* Multi-user access
* Permissions
* Secure data separation

5. Existing Features Migration
Every current HTML feature must work:

No feature removal allowed.
