How to Build an Approval Workflow (With Examples)
An approval workflow is a process that routes a request to the right people for review and records their decision before the work continues. Automating it removes email chains, speeds up decisions and gives you a complete audit trail.
Common approval workflows
- Purchase requests and purchase orders.
- Expense reports and reimbursements.
- Sales discounts and non-standard pricing.
- Contracts and legal review.
- New vendor or customer onboarding.
- Access requests to systems and data.
The building blocks
- Request: a form or a record in a system that starts the workflow.
- Routing rules: who approves, based on amount, department, region or risk.
- Approval step: approve, reject or request changes, from email, Slack, Microsoft Teams or an app.
- Escalation: reminders and escalation when an approver does not respond.
- Outcome: what happens next, such as creating a purchase order in the ERP or sending a contract for signature.
- Audit trail: who approved what, and when.
Example: purchase request approval
An employee submits a purchase request through a form. Requests under $1,000 go to the team manager; requests above go to the manager and then finance. Approvers act from Slack. Once approved, the workflow creates the purchase order in NetSuite or SAP, generates the PDF and emails it to the supplier. Rejected requests return to the requester with comments.
Design tips
- Keep rules simple and visible, and avoid more than three approval levels.
- Show approvers everything they need in the request itself.
- Set clear deadlines and escalation paths.
- Automate what happens after approval, not just the approval.
