Example scenario

Growing procurement workflow

A team processing 7,200 purchase orders a year wants to reduce approval lag and downstream cleanup from inconsistent PO handling.

Why this matters

PO software is often justified by cleaner control and spend visibility, but the case usually lands better when tied to reduced admin work and fewer mismatches.

This calculator focuses on approval-cycle savings and fewer PO-related cleanup tasks downstream.

It is especially useful when purchase requests and PO approvals are still managed across email, PDFs, and spreadsheets.

When to use this calculator

Use this when evaluating PO workflows and you need a simple case before procurement or AP tooling conversations get bundled together.

The model works well when the team can estimate current PO volume and the cost of mismatches or approval delays.

How the math works

Annual labor savings = purchase orders per year × minutes saved per PO ÷ 60 × hourly cost
Annual mismatch savings = mismatches avoided per year × cost per mismatch
Total annual savings = labor savings + mismatch savings
ROI = (total annual savings - first-year investment) ÷ first-year investment

Common questions

Should budget-control savings be included too?+

Only if you have a clean estimate. Most teams keep the base model focused on approval and mismatch savings to avoid over-claiming.

Does PO software overlap with AP automation?+

Often yes, but the buying trigger is different. PO tools are usually evaluated earlier in the spend-control workflow, before the invoice arrives.
