How we work this out
  • Handling cost = invoices × handling time × hourly cost, over 12 months. Touch-free invoices count as 1 minute of oversight; the rest take your manual minutes.
  • With Kefron AP, 70% of invoices go through touch-free (or your current rate, if higher), in line with what customers typically see (70%+). Exceptions take about a third of today's handling time, because the data is already captured, matched and routed.
  • The automation levels pre-fill an assumed touch-free rate (0%, 15%, 35%, 60%, 85%). Adjust it if you know your own.
  • Payments at risk = annual invoice spend × your duplicate or error rate. It's shown separately and not counted in the saving.
  • One FTE = 1,650 working hours a year. Figures are estimates, not a quote, and exclude software cost.
  • Benchmarks: Kefron / Censuswide survey of 200 US finance professionals, 2026. Figures rounded.
