Governed chains
Company presets or custom paths from your Microsoft directory — with stage progress everyone can see.
- Pick a preset or build a custom path
- Attach the document once
- Return, reject, vet, or add an approver mid-flight
Chainline
Email is not an approval system.
Document approvals for Microsoft 365. Governed chains in Entra ID and Teams — audit-ready by default.
Why inbox approvals fail
Important documents still bounce through inboxes and chat threads. Approvers change mid-flight. Versions multiply. When audit asks who signed off, the answer is a scavenger hunt. Simple Approvals and Flow apps do not cover presets, vetting, and auditor separation.
One workspace. A clear chain. Proof when you need it.
Act where you work
Notifications and a Teams personal tab keep decisions in the Microsoft estate your users already trust.
- Microsoft Entra ID sign-in — no separate password
- Teams notifications via Microsoft Graph
- People picker backed by your tenant directory
Audit-ready by default
Trails, roles, and exports without bolting on a second system. Auditors review without editing live decisions.
- Immutable action history
- Files stay private with short-lived access links
- Role separation for requesters, approvers, and auditors
Requests and versions
Draft and submit with title, description, and attachment. Resubmit after reject with a documented response.
- Approvers can upload a new version before final lock
- Timeline of every stage
- Final approval locks the document
