Automation ROI Calculator for Australian Businesses for Trades & Construction
Estimate the hours and dollars your trades or construction business would reclaim by automating quoting, scheduling or invoicing.
Last updated 31 May 2026
This automation ROI calculator is set up for trades and construction businesses weighing whether to automate manual admin like quoting, job scheduling, timesheets or progress invoicing. Enter how many people handle the task, the hours it takes and their loaded cost, and the calculator shows the hours and dollars you would reclaim, the payback period and first-year return. Trades businesses often lose a full day a week per person to paperwork that moves between the field, the office and the accountant, so even a modest time saving across a small team adds up quickly to real money back on the tools.
How to use this tool
- 1
Describe the task
Enter how many people do it and how many hours each spends on it per week.
- 2
Add the costs
Enter the loaded hourly cost, the expected time saving, the one-off build cost and any monthly tooling.
- 3
Review the return
See the annual saving, payback period and first-year ROI to decide whether the automation is worth it.
What counts as a loaded hourly cost
The loaded hourly cost is what an hour of an employee actually costs your business, not just their wage. It includes the base pay plus superannuation, which is currently 11.5%, along with on-costs such as payroll tax, workers compensation, leave loading and a share of overheads. A staff member on 70,000 dollars a year often costs closer to 90,000 to 100,000 dollars once these are included, which works out to roughly 50 to 55 dollars an hour. Using the loaded figure rather than the bare wage is the single most important input, because automation frees up that fully loaded hour, not just the wage portion.
Estimating a realistic time saving
Most automation projects do not remove a task entirely. A well-scoped automation typically removes 60 to 90 percent of the manual effort, leaving a small amount of human oversight for exceptions and quality checks. Data entry, copying figures between systems, chasing approvals and generating routine documents are usually at the higher end because they are rule-based. Tasks that need judgement or client conversation sit lower because a person still needs to be in the loop. Being conservative with the time-saved percentage gives you a payback period you can defend to a board or business partner.
Reading the payback period and ROI
The payback period tells you how many months of labour saving it takes to recover the one-off build cost, after allowing for ongoing tooling. A payback under twelve months is generally considered strong for a process automation, and many rule-based automations pay back in three to six months. The first-year ROI expresses the net saving as a percentage of the total first-year cost, so a result of 150 percent means you save one and a half times what you spend in the first year. Beyond year one the build cost is already recovered, so the saving compounds, which is why automation tends to look even better over a two or three year horizon.
From estimate to scoped build
A calculator gives you a defensible estimate, but the real numbers depend on which systems are involved, how clean the data is and where the exceptions hide. The figures here are the same ones we validate in a free assessment before scoping a build, where we map the current process, confirm the time it consumes and identify the integration points. If the payback looks promising, that conversation turns the estimate into a fixed scope with clear milestones, so you are never committing to an open-ended project. Use the result below as your starting business case.
Where trades and construction businesses save most
The biggest automation wins in trades and construction are usually in the quote-to-cash cycle. Re-keying job details from a site visit into a quote, then into a job card, then into an invoice and finally into accounting software is the same information entered four times. Automating that flow, along with chasing quote approvals and sending payment reminders, typically removes most of the office admin without changing how the crew works on site. Scheduling and timesheets are the next tier, where syncing field data back to payroll removes a weekly bottleneck. Because trades margins are tight and labour is scarce, reclaiming office hours often matters more than the dollar saving alone, since it lets your team quote more work without hiring another administrator.
Worked example
Three staff each spend six hours a week on manual invoice processing at a loaded cost of 55 dollars an hour.
- People
- 3
- Hours each per week
- 6
- Loaded hourly cost
- $55
- Time saved
- 70%
- Build cost
- $12,000
About 655 hours and $36,000 of labour reclaimed per year, with payback in roughly five months.
Even after the build cost and ongoing tooling, the net first-year saving comfortably exceeds the investment, which is a strong signal to scope the build.

Frequently asked questions
How do I calculate the ROI of automating a manual process?
Work out the annual cost of the task by multiplying the people, weekly hours, 52 weeks and the loaded hourly cost. Multiply by the expected time saving to get the annual labour saving, then compare that against the build and tooling costs. The calculator above does this and shows payback and first-year ROI.
What is a realistic payback period for a business automation project?
Many rule-based automations pay back in three to six months, and a payback under twelve months is generally considered strong. Projects that touch several systems or need custom integration can take longer to build but often save more, so judge each on its net first-year saving as well as payback.
How do I estimate how many hours automation will save?
Start from how long the task takes today, then apply a conservative time-saving percentage. Rule-based work like data entry and document generation often saves 70 to 90 percent, while tasks needing judgement save less. It is safer to under-estimate the saving so your business case still holds if reality is messier.
Should I include ongoing software costs in automation ROI?
Yes. Subscriptions, hosting and licences are real costs that reduce the net saving, so the calculator subtracts annual tooling from the labour saving before showing the return. Including them gives you an honest payback period rather than an optimistic one that ignores the running cost.
What is a loaded hourly cost and why does it matter?
The loaded hourly cost is the wage plus superannuation, payroll tax, leave and a share of overheads, which is what an hour of work truly costs. Automation frees up that full cost, not just the wage, so using the loaded figure produces a far more accurate return than using the bare hourly wage.
How much does it cost to automate a workflow in Australia?
It varies with complexity, from a few thousand dollars for a single rule-based automation to tens of thousands for a multi-system workflow with custom integration. The calculator lets you model any build cost, and a free assessment turns that estimate into a fixed scope so there are no open-ended surprises.
