Measuring the return on automation: time, errors and control

How to work out whether an automation is worth it, using a simple calculation and a real payment approval project that went from 1.5 man-days to 0.2.

Measuring the return on automation: time, errors and control

Three kinds of return

When people talk about the return on automation, they usually mean time saved. Time is the easiest return to measure, but in finance it is often not the most important one. A useful assessment looks at three things:

  • Time: hours your team no longer spends on the task.
  • Accuracy: errors that no longer happen, and what each one would have cost.
  • Control: approvals, records and checks that now happen every time.
Three kinds of return on automation: time saved, errors avoided and control gained
Time is the easiest return to count. Accuracy and control often matter more.

Time: the simple calculation

The calculation for time is straightforward:

Annual time saved (Time per run before − time per run after) × number of runs in a year

Take our payment approval project. Each payment run used to take 1.5 man-days: pulling overdue bills into a spreadsheet, getting the CFO's approval by email, and building the bank file by hand. With Zenith 360 the same run takes 0.2 man-day.

If the company runs payments once a week, that is 52 runs a year:

  • Before: 1.5 × 52 = 78 man-days a year
  • After: 0.2 × 52 = 10.4 man-days a year
  • Saved: 67.6 man-days a year, roughly three months of one person's working time

Accuracy: the errors you no longer make

Errors are harder to count than hours, but they are often more expensive. Look back over the last year and list what went wrong in the process you plan to automate:

  • payments to the wrong account or for the wrong amount
  • bills paid twice
  • e-invoices reported late, putting your customer's input tax credit at risk
  • PF, ESI or TDS paid after the due date, with interest
  • figures in the MIS that did not tie back to the books

Put a cost on each, including the time spent fixing it. Even one avoided error a year can justify a modest automation.

Control: harder to price, easy to value

Some returns do not show up in hours at all. After the payment project, every payment list carries the CFO's recorded approval, the person who prepares the list cannot approve it, and every step is logged. Auditors, directors and lenders value that kind of control, and it reduces the risk of fraud in a way no time calculation captures.

Costs to set against the return

A fair assessment includes the costs as well:

  • building and testing the automation
  • any software licences
  • monitoring and support once it is live
  • your team's time for mapping, testing and sign-off

A simple way to present it

Item Before After Annual effect
Time per payment run 1.5 man-days 0.2 man-day 67.6 man-days saved (weekly runs)
Approval of payment list By email, not always recorded Recorded in Zenith 360 for every run Full approval trail
Bank upload file Built by hand Generated from the approved list No manual formatting errors

A table like this, one row per benefit, is usually enough for a management decision.

Measure again after go-live

Record the "before" figures while you map the process, then measure the same figures two or three months after go-live. The comparison shows what the automation really delivered, and it helps you choose what to automate next.
