“Will this pay for itself?” is the most sensible question anyone asks about automation, and the least often answered with real numbers.
Here are some from real projects. Client names are withheld and all figures are as reported to us.
The numbers
Invoice processing. A finance team was manually processing 600+ supplier invoices and 300+ customer invoices every month. Now the system reads the PDFs, extracts the data and codes the invoices, and their accountants review and approve. Manual processing dropped from 3-4 days to near zero.
Review work. A process that took 3 hours now takes around 20 minutes. Separately, a 3-hour process for a £200M financial services company came down to 3 seconds.
Advisor documents. A 10-page file note that took 3-4 hours by hand was completed in about 20 minutes with the system. In one project, work that used to take advisors six weeks now takes about a minute, which the client valued at around £250K of reclaimed capacity.
Hosting and tooling costs. A business owner spending £3,000 a month on a build platform moved to a different setup and now spends £75 a month while still building faster. Another client saved £3,000 a month after moving the same way.
What these have in common
None of them started with “let’s use AI.” Each started with a specific, repeated, painful piece of work. That matches something we say often: the first step is stopping unnecessary work, and the second is automating what’s left.
Be honest about the limits
- Verify everything. AI can produce credible-sounding output that’s wrong, so figures and claims need to be checked against sources.
- Budget for review. Note the phrase in the invoice example: your accountants review and approve. The human check is part of the design.
- Expect iteration. Reaching a top-quality output often takes several rounds of refinement. Anything that claims to be perfect first time deserves suspicion.
- Token costs are real. As one client put it, it burns a lot of tokens, but in the end it works. Count that in your numbers.
Work out your own payback in five minutes
- Pick one repeated task.
- Hours per month × loaded hourly cost = current monthly cost.
- Estimate the hours after automation (be conservative).
- Subtract, then compare with the build and running cost.
If the payback period is under 12 months, it’s worth a proper conversation. If it’s under three, you’re probably already late.
Send us the one task you’d most like to never do again. We’ll tell you honestly whether it’s worth automating.
