Planning Team Permissions for a SaaS Product
Team permissions define what a person can do with a customer’s records. They affect invitations, daily work, account administration and support. Start with actions people need to perform, then design roles that make those actions understandable without giving every teammate unrestricted access.
Should you define actions or roles first?
Map a representative task such as creating, assigning and approving a service request. List who can read the request, change its content and approve the result. Viewing a record and approving it are separate permissions even when both happen on the same screen.
Use concrete examples to resolve uncertainty. Can an invited teammate see existing requests before accepting? Can a manager edit another person’s draft? A permission matrix should answer those questions in the language of the product, not just list administrator and member labels.
How do you keep customer accounts separate?
A shared SaaS application may serve several organizations. Each request must be evaluated against the current person, their organization and the record they want to access. Knowing a record identifier should not be enough to read or change it.
OWASP recommends denying access unless it is allowed and checking permissions on every request. Apply those principles to downloads, searches and background actions as well as ordinary screens. Hiding a button helps explain a role but does not enforce that role in the backend.
How should invitations and role changes work?
Decide who can invite teammates and which role an invitation grants. Include expiration, repeated invitations and an invitation sent to the wrong person in the review. A pending invitation should not create broader access than the product owner intended.
When someone leaves, decide what happens to their assigned work and active sessions. Removing membership should have a clear effect on future access. Keep enough history to explain prior actions while transferring unfinished responsibilities to an appropriate owner.
How do you test permission boundaries?
Create test users in separate organizations with different roles. Try the same action from each account, including a direct request that bypasses the visible navigation. Review a record after membership changes and check that exports follow the same access rules.
For an MVP, a small set of well-defined roles is easier to review than many overlapping options. Bring the action matrix and customer boundaries into SaaS planning. Expand permissions when a real workflow requires more control, with tests that show what the new role can and cannot do.
