These figures estimate the value of released capacity, rather than guaranteed cash savings. Actual results depend on your workflow. Try a lower handling time to build a more conservative case.

A useful starting point.
A bigger picture.

Use the estimate alongside what you know about your team. Time saved is one part of the value of AP automation.

Ground it in your own workflow

Use measured handling time and fully loaded staff costs. Compare a typical month with a busier one.

Keep the wider benefits separate

Fewer errors, less chasing, reduced duplicate-payment risk and easier audit preparation are not priced into this estimate.

Understand the payback

Around 1 month of modelled net savings would equal your annual plan fee. This uses labour value after monthly software costs.

What is AP automation ROI?

AP automation ROI compares the financial value of time released from manual invoice processing with the cost of the automation software. A useful estimate shows both the net saving after software fees and the hours returned to the finance team.

How does the AP automation ROI calculator work?

Enter your monthly invoice volume, current handling time per invoice, and loaded hourly staff cost. The calculator estimates annual labour capacity released, subtracts the selected ArrowBill plan fee, and shows net annual savings, return on fee, and payback period.

What costs does AP automation reduce?

This calculator measures staff time spent capturing, coding, approving, posting, and chasing invoices. AP automation may also reduce rework, late fees, duplicate-payment risk, and audit preparation, but those benefits are not included in this estimate.

How is the AP automation payback period calculated?

The calculator divides the annual ArrowBill plan fee by the estimated monthly labour saving after the monthly plan fee. The result is the number of months needed for the modelled net monthly saving to equal one year of software fees.

What assumptions does the calculator use?

The model assumes that ArrowBill releases 90% of the manual handling time entered, leaving 10% for human review and exceptions. It uses 40 hours across 4.33 weeks for one monthly FTE and applies the selected Solo or Team volume pricing. Add-ons are excluded.

Are the estimated AP automation cost savings guaranteed?

No. The result is an estimate based on the figures you enter and the stated assumptions. Use measured handling time where possible, include fully loaded staff cost, and run conservative, expected, and higher-volume scenarios before using the output in a business case.

How does automated invoice processing compare with manual processing?

The manual baseline multiplies invoice volume by the current minutes spent on each invoice and the loaded hourly cost. The automated estimate applies the stated time-recovery assumption, retains time for review and exceptions, and deducts the ArrowBill plan fee.
