We’re at a point where our automation TCO has become a mess of line items. We’re on Camunda’s enterprise tier, which is expensive, but then we also have separate subscriptions for OpenAI, Anthropic, sometimes Deepseek or a specialty model. Each one has its own API keys, its own billing cycle, its own documentation.
What I’m trying to understand is the real breakdown of costs and whether consolidating makes sense. I can see the licensing part—one subscription for 400+ models instead of individual subscriptions. But I’m wondering about the hidden costs that don’t show up in the licensing spreadsheet.
Like, how much are we actually spending on developer time to manage all these integrations? When someone needs to add a new model, how much engineering effort is that? Are we losing money on unused models because we’d already paid for them? And if we switched to a unified subscription setup, would that actually reduce operational overhead, or does it just shift the cost somewhere else?
I’m trying to build a real TCO model that includes both licensing and the operational complexity of managing multiple tools. Has anyone actually calculated this and been willing to share the breakdown? What surprised you most about where the actual money was going?
I built this model for our company six months ago. The Camunda licensing was about 40% of the total automation cost. The rest split between developer time managing integrations (35%) and actual API usage (25%).
That integration time was the killer. Every time someone wanted to use a new model, it meant writing new authentication logic, testing it, documenting it, maintaining it. We were burning maybe one engineer at 20% capacity just on this stuff.
When we looked at consolidating to a single platform with unified API access, the licensing savings were real, but the integration overhead disappearing was bigger. We cut that engineer’s time down to maybe 5% capacity. That’s not reducing headcount, but it freed them up for actual feature work. In TCO terms, that’s significant.
We also discovered we were paying for models we barely used. Had an Anthropic subscription that we touched maybe twice a month, but the minimum spend made it not worth canceling. Switched to a platform where you only pay for what you actually use, and that alone saved us about $8,000 a year. Doesn’t sound huge until you realize that’s just one unused subscription—we had three or four of these.
The TCO that matters isn’t just what’s on the invoice. It’s what you’re throwing away on low-usage subscriptions, plus engineering time wasted on repeated integration work.
That said, consolidating assumes the unified platform actually has all the models you need at feature parity. We had specialized models for some work, and the unified platform’s versions were different enough that we had to retrain some workflows.
The real question isn’t whether consolidation saves money—it usually does. It’s whether it saves you enough to justify the migration effort. Going from Camunda plus multiple subscriptions to a unified platform requires rewriting workflows, retraining the team, potentially rebuilding some customizations.
For us, that was worth it. The year-over-year TCO is significantly lower. But if your Camunda setup is heavily customized and your particular mix of AI models is optimized for your use case, the switching cost might eat most of the savings.
Do the math on actual migration effort, not just licensing arbitrage.
