What is manual work costing your firm?

Every week, people on your team act as the pipe between systems that don't talk — re-typing, chasing, copying, reconciling. It feels like just part of the job. Priced up, it's usually one of the largest costs a small firm never sees on an invoice. This works it out from your own numbers, using a wage figure you can check.

Start with one hour.

One person, one hour a week, for a year — at a loaded UK wage of about £19 an hour — costs roughly £870. That's the atom. No firm loses just one hour, though: it loses hours, across a team, every week. So the real number is that atom multiplied by two things — how many people, and how many hours each.

Who does the manual workLoaded wage (+15% NI)£/year per 1 hr a week
Data-entry administrator£16.62£765
Book-keeper / payroll clerk£18.78£864
Office manager£22.08£1,016
Blended default used below≈ £19.00£874

Wages: ONS Annual Survey of Hours and Earnings, April 2025 (provisional) — median hourly pay excluding overtime, occupation codes 4152 / 4122 / 4141 — plus 15% employer National Insurance (2026-27 rates). The £19 blend sits between a book-keeper and an office manager; it's a rounded average of two figures on this table, not a new number. Adjust it below to fit your team.

Now scale it to your firm.
