The AI Tax and the End of Predictable Software

SaaS scaled cost by seats. AI scales cost by curiosity. The winners design for constraint.

SAAS IS CAPEX IN DISGUISE. AI IS OPEX ON STEROIDS.

This isn't just a tech shift. It’s a complete inversion of the cost structure.

For twenty years, SaaS trained us on a comfortable lie: predictable, per-seat pricing.
In reality, it was predictable waste. We bought 1,000 licenses, 200 people used them, and we paid for 850 empty seats just in case.

We budgeted for access, not performance.

Then AI arrived. And the model broke.

AI isn't fixed cost. It’s variable. Every prompt, token, and API call burns money.

This is the AI Tax.
Enterprise AI workloads now consume 60% more compute than traditional analytics, pushing gross margins for AI-enabled products from 80% down to 40%.
For companies and users, that means costs rise directly with activity, not with seats or licenses. Every query, every model call, every decision consumes compute and budget.

That creates a new paradox:
SaaS tools reward constant usage.
AI tools demand intentional usage.

CFOs see risk. Strategic operators see clarity.
AI costs scale with activity, not headcount.
It finally forces organizations to connect spending directly to value.

The question isn't "How much per seat?"
It’s "What’s the ROI per inference?"

A $60 unused seat is a waste.
A $0.60 AI query that saves 45 minutes of expert time is gold.


THE PRAGMATIC PATH FORWARD

  • Budget for Outcomes, Not Tools. Retire the "AI Budget." Fund business outcomes like "cut contract review time by 80%" or "shorten quote cycle to one day." Treat AI cost as part of that mission’s COGS.
  • Master Unit Economics. Track value per inference, cost per insight, and margin per workflow. Create dashboards that show how each model or use case earns its keep.
  • Architect for Constraint. Design efficiency in. Cache the 20% of queries that generate 80% of the total volume. Batch low-value requests. Route heavy workloads to lower-cost models and measure latency against ROI.
  • Value-Gate Ruthlessly. High-stakes, high-impact use cases deserve premium inference. Routine or cosmetic tasks do not.
  • Deploy Hybrid. Keep experiments on hosted APIs for speed. Shift stable, high-volume processes to controlled infrastructure once economics are proven.
  • Budget Tokens Like Fuel, Not Seats. Every team has a fuel tank. They decide where to drive, how far, and what business result justifies the trip. Refill based on verified value creation.

The winners won't have the biggest AI budgets.
They'll have the cleanest cost loops.

Because in this new stack, efficiency isn't how little you spend.
It’s how fast you learn per dollar burned.

Your AI strategy can't mirror your old SaaS playbook.
The economics reward precision, not volume.

What’s your cost per breakthrough?
