Illustrative example. The figures below are a worked model to show how the maths works, not a specific client result. Your actual numbers will differ with your team, your rates, and the scope of the implementation.
This is the return on a NEXGEN OS™ implementation, our productized AI Operating System. Take a $20M-revenue, operations-heavy Australian SMB. If it removes 21 hours a week of manual staff work at a blended cost of $60 an hour, that is roughly $60,000 a year in recovered capacity against a one-time build from $15,000. The result is payback from about three months, then around $60,000 a year recurring. And the admin load behind that number is real: 1 in 5 Australian SMB owners spend 21 to 40+ hours a month on financial admin alone, per Dext's “Built for Bigger Things” report (2025).
The maths behind NEXGEN OS™
Three inputs drive it: hours recovered, the blended hourly cost of that time, and the one-time implementation. Annualised over 48 working weeks (allowing for leave), the example looks like this:
| Hours recovered per week | 21 |
| Blended hourly cost | $60 |
| Annual recovered capacity (48 weeks) | ~$60,480 |
| One-time implementation (midpoint) | $25,000 |
| Payback period | ~5 months |
| First-year net return | ~$35,480 |
At $15,000 payback lands closer to three months, and a larger $35,000 build closer to seven. Every year after the first, the recovered capacity keeps compounding while the implementation cost does not repeat. That compounding is the part a rented tool subscription never gives you: because you own the NEXGEN OS™ system outright, year two is pure return on infrastructure you already have.
What this leaves out (read this part)
- Recovered hours are capacity, not a cheque. The value is real, but it shows up as more output and less overtime, not cash in the bank.
- Ongoing optimisation is extra. Keeping the system improving is optional, through NEXGEN OS Scale from $3,000 a month, which you net off the annual saving. Month zero is on us, and you choose at day 30 with your own savings numbers in front of you.
- Ramp takes time. The full saving lands once the workflows are live and trusted, not on day one.
- The model is deliberately conservative. 21 hours of senior coordination time is usually worth more than the $60 blended rate suggests.

Common questions
Are these numbers from a real client?
No. This is an illustrative model to show how the maths works, not a specific client result. Your figures will differ with your team size, rates, and scope.
What is the ongoing cost?
The implementation is a one-time fee from $15,000. Keeping it optimised is optional, through NEXGEN OS Scale from $3,000 a month. You own the system either way.
