How to justify an internal tool
Internal tools are hard to approve because the benefit is time saved, and time saved is easy to dismiss. The model below turns it into a number a finance team can argue with.
The three components
Hours recovered: people multiplied by hours per week multiplied by loaded hourly cost. Error cost: rework, credits and penalties caused by manual mistakes. Visibility value: decisions that currently wait for someone to compile a report.
Only the first is easy to quantify, so quantify it conservatively and treat the others as upside rather than padding.
A worked example
Six staff spending five hours a week each on manual order entry is thirty hours weekly. At a loaded cost of ₹500 an hour that is ₹15,000 a week, roughly ₹7,80,000 a year. A tool that removes seventy percent of that work pays back a modest build in under a year.
The adoption discount
Apply a discount for adoption. Tools that add steps, duplicate existing entry or arrive without training get used for three weeks. Design the tool around the current workflow before changing the workflow.
Common questions
- Should the tool replace the spreadsheet entirely?
- Ideally the tool becomes the source of truth and exports to the spreadsheet for analysis. Parallel entry in both places is where adoption dies.
- What is a realistic payback period?
- Twelve to twenty-four months is common for internal tools. Anything beyond three years usually means the process should be simplified first.
Next step
If this question is live in your business right now, describe the situation and you will get a written view on the options, including whether you should build at all.
