Here’s my dilemma. Our CFO sees Camunda on the budget every month—specific line item, specific amount, predictable. It’s easy to justify to the finance board because it’s a clear cost.
Now I’m proposing we move to a different platform—one that consolidates licensing, offers access to 400+ AI models in one subscription, and theoretically reduces our overall TCO through faster implementation and reduced maintenance. It sounds great when I explain it, but my CFO has one question: “Show me the numbers.”
And I’m realizing that the financial argument is harder than it looks. The licensed cost might actually go down slightly, but that’s not the whole story. I need to account for developer time saved on integration work, maintenance costs, and implementation speed. But how do I quantify that? “We’ll need fewer developers in the long run” is not a budget line item that passes scrutiny.
I’ve also got to account for migration costs and the risk that something goes wrong during the transition. And I need to prove that the unified subscription model is actually more cost-effective than itemizing subscriptions.
Has anyone actually built a business case for this kind of platform switch that passed financial review? What numbers did you use, and what assumptions did you have to make? How did you handle the skepticism about cost savings that aren’t on the license bill?
We approached this differently than most. Instead of trying to prove that TCO would go down overall, we proved that cost per automation deployment would go down significantly. We tracked how long it took to go from requirement to production in our Camunda setup—about three weeks average. We modeled how long it would take in the new platform based on trial work—about one week.
Then we looked at what we were deploying annually—roughly 12 new automations per year. That’s eight weeks of developer time per year that we’d save. At our developer costs, that was about $80K. Our licensing savings were maybe $15K. Together, that’s $95K in year-one costs.
The migration cost was about $40K. So net savings in year one were only $55K, but year two and beyond were the full $95K. That was a number finance could actually work with because it was tied to measurable internal metrics, not vendor promises.
The key insight was that we didn’t try to prove we’d reduce headcount. We proved we’d do more with the same headcount. That’s easier to justify because you’re not asking for immediate cost reduction—you’re asking for efficiency improvement that lets you scale without hiring.
We also built in a break-even analysis. “If we deploy fewer than 8 new automations per year, we don’t break even on the switch. If we deploy more than 12, we’re looking at real savings.” That gave finance a clear threshold, and they were comfortable betting on us hitting it.
The itemized Camunda budget issue is real. One way to address it: model your new platform costs the same way. Show the licensing cost, then show the development cost as a separate line. Instead of “we’re switching to save money,” frame it as “we’re restructuring how we account for automation costs.” No-code builders that let business users build simple things reduce development costs. Ready-made templates reduce implementation time. You’re not hiding costs; you’re allocating them differently.
That transparency actually helped us. Finance appreciated that we weren’t trying to make costs disappear—we were showing exactly where the savings came from.
