Your AI Budget Doesn’t Exist. Build One in 30 Minutes.

When was the last time you looked at your business’s credit card statement and could identify exactly what you’re spending on AI?

Not what you think you’re spending. What you’re really spending. Every subscription, every usage overage, every tool that silently upgraded from a free trial to a paid plan while you were focused on running the business.

If you’re like most small business owners I talk to, the answer lies somewhere between “never” and “I’d rather not look.” The invisibility is a bigger problem than the spending itself. You can’t manage a cost you can’t see, and right now most small businesses are spending on AI without any system for seeing the total.

This post is about fixing that. It takes 30 minutes.

The Budget Line That Doesn’t Exist

Most businesses have a line item for software. They have a line item for marketing. They have a general sense of what goes to payroll, rent, and supplies. Very few have a line item for AI.

The AI costs are there. They’re scattered. A subscription one person on the team signed up for three months ago. An API usage charge on the company card that nobody remembers authorizing. Your CRM might have quietly moved you to a higher tier with AI features included. I had one of these myself: a free trial I forgot to cancel, two months of charges on my statement before I caught it.

McKinsey’s Enterprise AI FinOps survey from May 2026 found that 20 to 30% of AI spending goes unaccounted for in large organizations. These are companies with full IT departments, procurement teams, and vendor management processes. Only 20 to 25% of them have mature practices for tracking and managing AI costs.

If companies with dedicated infrastructure for this still can’t see a quarter of their AI spending, a five-person business with no IT function is almost certainly doing worse. Not because the team is careless. Because nobody set up the tracking in the first place.
