The challenge
The purchase-order system ran on SharePoint Designer 2013 workflows. Their support in SharePoint Online ended in 2020, and Microsoft retired them for existing tenants on 2 April 2026.
What we built
- 01
Multi-level approval by role
Requester, manager, procurement and finance, with notifications and reminders.
- 02
A smarter PO form
Dynamic fields by category, with validation.
- 03
Dashboards for every role
My Requests, My Approvals, Pending and Completed, filtered by department and status.
- 04
Export
To Excel and PDF.
12 workflows, moved one by one
Each legacy workflow was rebuilt in Power Automate and tested in parallel with the old one before the switch.
