Approvals that move work forward.

Chainline is the document approval workspace for Microsoft 365 — clear chains, decisions in Teams, and an audit trail your organisation can trust.

The problem

Email is not an approval system.

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.

    Which version is final??

    Need sign-off trail for Q3

Chainline replaces this with one governed chain

  • Unclear ownership

    Nobody knows whose turn it is.

  • No durable trail

    Decisions live in deleted mail.

  • Awkward Microsoft sprawl

    Simple Approvals and Flow apps do not cover presets, vetting, and auditor separation.

The solution

One workspace. A clear chain. Proof when you need it.

Chainline gives every request an explicit path of approvers, keeps the file and versions in one place, notifies people in Teams, and records every action for compliance.

Notifications and a Teams personal tab.

Audit-ready by default

Trails, roles, and exports without bolting on a second system.

Sample path

Product mechanics

How Chainline works

  1. 1

    Sign in with Microsoft

    Your organisation's Entra ID. No separate Chainline password.

  2. 2

    Submit with a chain

    Pick a company preset or build a custom path with people search. Attach the document.

  3. 3

    Decide on the stage

    Approvers approve, return to a prior stage, reject for resubmit, request vetting, or add an approver.

  4. 4

    Trail everything

    Each action is recorded. Auditors review without editing. Files stay private with short-lived access links.

Submit for approval

Requesters pick a preset or build a custom chain from your Microsoft directory, attach the document once, and track every stage until final approval.

Approvers act in-app with a clear queue. Auditors read the full trail without touching live decisions.

Capabilities

Everything your approval process actually needs

Designed for organisations that outgrew email and outgrew one-size Approvals apps.

Draft and submit with title, description, and attachment. Track stage progress and timeline. Resubmit after reject with a documented response. Approvers can upload a new version with comments before final lock.

Who it's for

Built for teams that cannot afford fuzzy sign-off

IT

SSO, Teams packaging, dedicated deployment, clear admin controls

Compliance & audit

Trails, flags, exports, read-only auditor role

Procurement & operations

Presets for repeatable document types

Legal & HR

Version history and locked finals on sensitive packs

Best fit: mid-market and enterprise organisations standardised on Microsoft 365.

Packages

Straightforward packages. Most enterprises deploy dedicated.

Start from the demo, then we provision an environment for your tenant. Shared multi-tenant production comes later; serious buyers get isolation from day one.
