Consolidating separate AI model subscriptions into one—what's the real ROI calculation when you're managing eight different vendors?

Right now we’re paying for individual subscriptions to OpenAI, Anthropic, Google, and a few others. Each one has its own pricing tier, its own API limits, its own contract terms. It’s a mess from a procurement perspective, and I’m pretty sure we’re overlapping licenses and wasting money.

I’ve been looking at platforms that consolidate access to multiple models under one subscription. On the surface it sounds great for budgeting and simplicity, but I’m trying to understand if it actually delivers cost savings or just accounting convenience.

Here’s what I’m unsure about: when you consolidate under one vendor, do you actually pay less than the sum of your individual subscriptions? Or are you just bundling costs? And if different models are genuinely better for different tasks, does a consolidated approach force you to use suboptimal tools for some jobs?

I need to build a real comparison model, and I’m not even sure what variables to include. Usage patterns per model? Performance per dollar? Team adoption friction?

Has anyone actually done this consolidation and measured whether your total spending on AI went up, down, or stayed the same?

Consolidation saves 20-30% on licensing. You lose some optimization but gain procurement simplicity. The break-even happens around month 6.

Track usage per model first. Many teams pay for overprovisioned tiers they don’t use. Consolidation forces that visibility. That’s where the real savings come from.

The ROI isn’t just cost. It’s fewer contracts to manage, one billing cycle, unified rate limits. If that saves your team even a week a year in procurement work, it’s worth it.
