How to Estimate Automation ROI: A Practical Framework

The biggest mistake businesses make with automation is treating it as a technology decision. It's a financial decision. Before evaluating tools, you need to know: which processes are worth automating, what's the expected payback, and how do you measure success?

Start by auditing your team's time. For one week, have each team member log tasks that are repetitive, rule-based, and involve transferring data between systems. Sort the results by hours spent per week and hourly cost of the person doing the work. The top 5 items on this list are your automation candidates.

The ROI formula is straightforward: (Hours saved per month × Hourly cost) – (Monthly automation cost) = Monthly net value. A process that takes 20 hours/month of a $75/hour employee's time costs $1,500/month. If automating it costs $5,000 to build and $200/month to maintain, the payback period is 3.8 months.

But time savings are just the first-order benefit. Automation also eliminates errors (which have their own cost), increases throughput (the same team handles more volume), and improves consistency (every customer gets the same experience). These second-order benefits often exceed the direct time savings.

The most common automation targets in Australian SMBs: client onboarding workflows, invoice processing, report generation, lead routing and follow-up, data synchronisation between CRM and accounting, and support ticket triage.
