Example scenario
Mid-market AP team
A finance team processing 24,000 invoices a year wants to measure how much capture, routing, and approval automation could reduce invoice workload and exception cleanup.
Why this matters
AP automation usually wins support when teams can show what manual invoice work really costs today and how much of it can be removed.
This calculator makes the business case clearer by separating labor savings from exception-handling improvements.
It is especially helpful when the current AP process still depends on inbox routing, spreadsheets, and manual approvals.
When to use this calculator
Use this when evaluating AP automation platforms and you need a practical model before finalizing vendor pricing or rollout scope.
The model assumes the main value comes from lower touch time per invoice and a reduced share of invoices needing manual intervention.
How the math works
- Current annual labor cost = annual invoices × current minutes per invoice ÷ 60 × hourly cost
- Future annual labor cost = annual invoices × future minutes per invoice ÷ 60 × hourly cost
- Exception savings = annual invoices × exception reduction rate × cost per exception
- Total annual savings = labor savings + exception savings
Common questions
Should early payment discounts be included here?+
Only if you have a defensible estimate. Many teams keep discount capture as an upside case and use labor plus exception savings for the base model.
What if invoice complexity varies a lot by vendor?+
Use a weighted average for the base case or run separate scenarios for simple and complex invoice groups if the spread is large.
