System / responsibility / release
Role-based business portals
Make access reflect the real working relationship.
A supplier, customer and staff member may all need the same record with different privileges. Hiding a button does not define that boundary; each protected action must be checked on the server.
The paid engagement
We scope account relationships, record visibility, permitted actions and administrative recovery. A prototype uses synthetic organizations to expose ambiguous rules before production records are introduced.
Acceptance and boundaries
Testing includes direct URLs, changed identifiers, removed users and downloads. The handover describes how access is granted and reviewed. Hosting location, processor terms and retention are explicit owner decisions, not automatic guarantees from choosing a particular framework.
