Most AP teams focus on the headcount story. The bigger win is usually capacity — the same finance team handling more invoices, closer to the close, with the audit trail intact.

How we did the math
Every assumption, written down.
We won't pretend our calculator is your business case — but it should give a finance team a defensible starting point. Numbers below are the levers in play.
01Time per invoice — before
Whatever you set above. Manual AP teams typically spend 10–20 minutes per invoice end-to-end (capture, code, approve, post, file). Heavy paper environments run higher.
02Time per invoice — after
We assume ArrowBill recovers 90% of the manual handling time. The remaining 10% covers a quick human review for exceptions and edge cases.
03FTE basis
40 hours × 4.33 weeks ≈ 173 hours per month. Used to translate hours saved into FTE equivalents — labour savings themselves are calculated in raw hours × hourly cost.
04ArrowBill cost
Volume-tiered pricing on the plan you select above. Solo runs 45p / 35p / 25p per invoice; Team runs 70p / 55p / 45p across the same volume bands. Billed monthly. Add-ons and procurement modules are not included in this estimate.
