Procurement request approval with Power Automate: replace email with a controlled process
Procurement requests often start as one spreadsheet row and turn into several email threads. The problem is not only speed: it becomes hard to see who owns the decision, which budget is affected and why the request was approved. Treat the process as a state machine instead.
1. Start with a structured request
Collect everything needed for routing and later reporting at submission time. Do not let incomplete requests enter approval.
- requester and business unit
- cost centre
- amount and currency
- procurement category
- business justification
2. Make the routing predictable
Use amount, category, cost centre and role to select decision makers. For multi-stage approval, keep routing rules in configuration rather than duplicating flow logic.
- line manager
- cost owner
- procurement
- finance
- threshold-based approval levels
3. Return-for-changes is a normal state
Many requests need clarification rather than outright rejection. Support return, resubmission and version history while preserving the original decisions.
- returned for changes
- resubmission
- version history
- decision history
4. Add budget checks where data is available
If budget data exists, the workflow can flag requests that exceed a limit or require an additional approval level before they enter the main approval chain.
- budget lookup
- threshold check
- warning
- extra approval step
5. Give procurement executable data
After approval, procurement should not retype information from an email. Pass the approved request as structured data into purchase-order or ERP processing.
- approved specification
- supplier information
- purchase reference
- ERP integration
