Decisions that stick.
Trails that prove it.
Flow403 routes every document, approval request, or choice through a structured workflow - capturing every reviewer's response, every comment, and every revision in one immutable audit trail.
Informal approvals always break down
Most teams run approval processes through email chains and Slack threads. The results are predictable - and painful.
No single source of truth
Decisions are scattered across inboxes, channels, and comment threads that nobody can find six months later.
Unclear who approved what
When an auditor asks who signed off on a decision, nobody can give a straight answer with evidence.
Approvals stall with no visibility
Without routing rules, requests sit indefinitely. There's no reminder, no escalation path, no way to see the queue.
Revisions are untracked
When a document changes after review starts, there's no record of what changed or whether reviewers saw the latest version.
No defined consensus rules
How many reviewers need to agree? All of them? A majority? Without a rule, "approved" means different things to different people.
Compliance exposure
Regulated industries need timestamped, identity-bound proof of every approval. Email threads don't satisfy auditors or regulators.
Three steps. Full traceability.
From request creation to final decision, every action is captured in order.
Create a request
Submit a document, an approval request, or a choice request. Attach supporting files where needed and add context for reviewers.
Route through a workflow
A workflow template defines who reviews at each step and what consensus rule applies - unanimous, majority, percentage, or minimum count.
Every decision is recorded
Approvals, rejections, comments, and change requests are stamped with time and identity. Revisions are snapshotted. Nothing is ever lost or altered.
Any team that makes formal decisions
If you need to prove a decision was made - and by whom - Flow403 is built for your team.
Legal & Compliance
Document every sign-off on policies, contracts, and compliance obligations.
Finance & Procurement
Route purchase orders, budget requests, and vendor approvals through structured sign-off chains.
Product & Design
Get formal sign-off on specs, designs, and feature decisions before shipping.
HR & People Ops
Manage policy approvals, role changes, and HR decisions with documented records.
Built for real approval processes
Not a generic task tracker. Flow403 is purpose-built for decisions that need to be documented and defended.
Configurable decision rules
All-approve, majority, percentage threshold, or minimum count - chosen per workflow step and enforced automatically.
Multiple reviewers per step
Assign as many reviewers as a step requires. Each acts independently. The decision rule determines when the step resolves.
Immutable audit trail
Every action - approval, rejection, comment, change request - is recorded with a timestamp and actor identity. Records are never altered.
Revisions & resubmissions
When a reviewer requests changes, the requester revises and resubmits. Each revision is a full snapshot. The complete history is always preserved.
Secure file attachments
Attach documents, contracts, designs, and supporting files. Files stay protected with private access controls and are tied to request history.
Multi-team organizations
Organize work across teams and projects. Keep approval contexts separate while maintaining a unified audit history per organization.
Action items
Attach follow-up tasks to any request. Assign them to team members with due dates, track completion, and see all your open items from every request in one dashboard view.
Approve anything your team needs to decide on
Not every decision is a document review. Flow403 supports three focused request types so you can route the right content through the right workflow.
See full request type docsUpload a file for reviewers to assess and formally approve or reject.
Present reviewers with defined options where each choice can be simple text or include documents.
A combined text-and-question format for clear recommendation context plus structured reviewer response.
