How permissions work

5 rules

Scope every record, query, action, export and attachment to the authenticated workspace and authorized entity.

Keep preparation and independent approval separate where the process requires review.

Protect bank details, tax identifiers and private financial values at field level.

Treat an administrator’s technical access separately from business decision authority.

Record failed and successful protected actions in the retained audit history.
