Power Automate Workflows for Requisition Approvals (Templates + Rules)

Executive Summary

Traditional purchase order approvals often rely on emails, spreadsheets, and manual checks, which slow down decisions, create errors, and increase compliance risks. Power Automate makes this process faster and more consistent by using dynamic workflows and clear approval rules. Building on this, Hyperbots’ Procurement Co-pilot works alongside Power Automate to cut approval times by up to 80 percent, sync approvals instantly with ERP systems, and give teams real-time visibility into spend. Together, they help leaders drive efficiency, compliance, and stronger supplier relationships.

Why Automating Purchase Order Approvals Matters

Manual requisition approvals bring several challenges:

• Delays from chasing stakeholders for sign-off.

• Inconsistencies in compliance checks.

• Limited visibility into pending approvals.

• Audit risks due to missing documentation.

Automating with Power Automate workflows for automating purchase order approvals eliminates these pain points by:

• Standardizing the requisition process.

• Routing requests automatically to approvers based on business rules.

• Tracking SLAs in real-time.

• Providing an audit-ready trail of every decision.

Power Automate Purchase Order Approval: Core Features

When designed well, a Power Automate purchase order approval workflow brings structure, speed, and compliance to finance teams.

Key features include:

• Dynamic approvers: Workflows automatically identify and assign the correct approver based on department, spend threshold, or vendor category.
  
  

• Multi-stage approvals: High-value requisitions route to senior leadership, while routine purchases remain at mid-level approvals.
  
  

• Audit trails: Every approval or rejection is logged for compliance purposes.
  
  

• Notifications & reminders: Approvers receive automated alerts to prevent bottlenecks.

  
  

• SLA enforcement: Deadlines ensure requisitions don’t stall indefinitely.

Templates for Power Automate Workflows

Microsoft provides baseline templates to get started with requisition approvals. These templates can be customized to suit business needs.

Popular template structures:

1. Simple approval template – Directs requisitions to a manager for one-step approval.

2. Parallel approvals – Sends the requisition to multiple approvers at once.

3. Sequential approvals – Routes requisitions through multiple layers based on spend thresholds.

4. Custom SLAs – Adds time-bound actions if approvals are delayed.

Hyperbots helps finance leaders move beyond out-of-the-box templates, embedding AI-powered checks that validate budget, compliance, and vendor terms before approvals even begin.

The Role of Dynamic Approvers in Scaling Approvals

In growing organizations, hardcoding approval chains quickly becomes unmanageable. Dynamic approvers solve this problem.

With Power Automate, rules can assign approvers based on:

• Cost center / department of the requester.

• Spend thresholds (e.g., manager < $25k, VP < $100k, CFO > $100k).

• Vendor category (IT purchases routed to CIO office, HR tools routed to HR).

Hyperbots augments this by adding AI-driven policy validation, ensuring that requisitions meet compliance before being routed to approvers.

Enforcing SLAs in Power Automate Approval Workflows

SLAs (service-level agreements) prevent requisitions from stagnating. With Power Automate:

• Approvers are given deadlines (e.g., 48 hours).

• Automated reminders nudge them to act.

• Escalations re-route requisitions to higher authorities if deadlines are missed.

Hyperbots adds another layer by providing real-time SLA monitoring dashboards, ensuring finance leaders can spot bottlenecks before they impact operations.
