You're probably paying for AI twice. Here's the 20-minute audit.

Open your company card statement and count the AI charges. Not the software. Just the AI.

Most owners get to four before they slow down, and cannot say which of them the business actually needs. That is what paying for AI twice looks like: a Copilot seat and a ChatGPT seat for the same person, or a stack of $20 subscriptions sitting on top of a plan that already includes the same thing.

AI subscription costs for a small business are never one big line item. They are eleven small ones, and nobody owns the list.

Here is the 20-minute audit that fixes it. You need two admin pages you already have logins for, and no spreadsheet.

Two things changed this quarter

Google put Gemini in the price of the plan. Google Workspace now includes Gemini across its business tiers at no extra charge: Business Starter at $7 per user per month, Standard at $14, Plus at $22. There is a paid “AI Expanded Access” add-on for heavy users, but the base assistant comes with the plan you already buy. On August 11, Sundar Pichai said the Gemini app had crossed a billion monthly users. Google is buying distribution, not margin.

Microsoft kept Copilot as a separate bill, and put it on sale. Microsoft 365 Copilot Business is an add-on, not an inclusion. List price is $21 per user per month. It is discounted to $18 right now, and Microsoft’s own footnote says that offer runs between July 1, 2026 and September 30, 2026, applies to the first year only, and requires an annual commitment. It caps at 300 seats and sits on top of a Business Basic, Standard or Premium plan.

In plain English: one vendor folded the AI into the rent, the other still sells it as a room upgrade. If you have never checked which model you are on, you are probably buying both.

The 20-minute audit

1. Pull the real list (5 minutes). Not from memory. Search your bank or card statement for the last three months for the vendor names: OpenAI, Anthropic, Google, Microsoft, Perplexity, Grammarly, Otter, Canva, Notion, and anything with “AI” in the descriptor. Write down the amount and the person who uses it.

2. Check what your plan already includes (5 minutes). This is where the money is. On Google Workspace, Gemini is in your plan already, so every personal Gemini subscription on your list is duplicate spend. On Microsoft 365, a basic Copilot chat comes with your subscription, but the version that works across your own files, email and meetings is the paid add-on. Find out which one your team is actually using before you pay for either.

3. Find the seats nobody touches (5 minutes). Both admin centers show last activity per user. An AI seat with no usage in 30 days is a cancellation, not a training problem. Be blunt about it. There are usually more than you expect, because AI seats get bought in round numbers and assigned to whoever asked loudest.

4. Decide per person, not per company (5 minutes). The person who lives in Excel and Outlook all day is worth $18 a month. The person who checks email twice a day is not. Copilot Business has no seat minimum, so you can buy five instead of twenty five.

What a small business should actually pay for AI

Run it on a ten person team.

On Google Workspace Business Standard, that is $14 per user, so $140 a month, assistant included. Add nothing.

On Microsoft 365 Business Standard, that is $23.50 per user, so $235 a month, plus Copilot Business at the promotional $18 for the five people who will genuinely use it. Call it $325 a month.

Now add the layer most owners forget. Four personal ChatGPT Plus subscriptions at $20 each, expensed quietly, one line at a time. That is another $80 a month, $960 a year, for something three of those four people already have inside the plan you bought them.

That is the whole game. The waste is almost never the big platform decision. It is the small duplicate subscriptions that nobody put on a list.

The honest part

Two caveats, because the comparison is not as clean as those numbers make it look.

Google Workspace and Microsoft 365 are not the same product at those prices. Business Premium at $32 includes device management and security tooling that Workspace Standard does not, so a straight per-seat comparison flatters Google. Pick your platform on what your business actually runs on, then optimise the AI inside it. Switching email providers to save $9 a seat is a bad trade you will pay for in a migration.

And sometimes paying twice is correct. If someone needs a specific model for a specific job, buying that seat beats an awkward workaround. The rule is not “one AI subscription per business.” The rule is that every charge has a name attached and a reason you can say out loud.

The verdict

Worth it, and it takes one coffee.

This is the best twenty minutes available in your business right now, because it costs nothing and the savings repeat every month. The ten person example above found $960 a year in duplicate ChatGPT seats before anyone looked at dormant licences. You also end up with something more valuable than the money: a written list of who uses which AI tool, which is the exact list you will want the day one of those vendors has a breach.

If you are on Microsoft, do this before September 30. The $18 rate and its annual commitment both land on that date, and a year-long contract is a decision worth making on purpose rather than by default.

Reading about AI is free. Paying for it twice isn’t. If you want someone to look at the whole stack, what you own, what you rent, and what your team signed up for without telling you, that is BlueFort IT’s day job. For the charges that never made it onto any list, start with shadow AI. And if you are weighing Copilot specifically, we already went through what “free” AI in Excel really costs and Copilot Cowork’s per-task meter.
