If AI now does part of the work on a client project, who should pay for the AI? It is a question more freelancers are asking as subscription bills climb and usage-based tools (the ones that charge per image, per minute of video or per task) creep into everyday work. Some are adding an “AI tools” line to their invoices. Others are quietly absorbing the cost. As we head into 2027 pricing season, it is worth thinking this through properly, because the wrong answer can cost you both margin and trust.
The signal from the big end of the market
On November 6, Anthropic added a beta feature to Claude that lets eligible Enterprise organizations tag projects with codes, such as a client or matter number, and see most of their AI spend broken down by tag. It is listed in the Claude release notes. Law firms and agencies have tracked billable hours by client code for decades; now AI spend is getting the same treatment.
When enterprise tools start measuring something per client, it usually means clients will eventually start asking about it. That does not mean you should copy the enterprise approach. In fact, for most solo businesses, copying it would be a mistake.
Why itemizing AI costs is usually a trap
The instinct to add an “AI tools: $40” line feels fair and transparent. In practice, it tends to cause three problems.
It invites the wrong conversation
Clients do not itemize your laptop, your accounting software or your internet connection. The moment you itemize AI, you signal that AI is a separate thing that did part of the job. The client’s next thought is often not “how transparent” but “if a $20 tool did this, why am I paying for the rest?” You have turned a conversation about results into a conversation about inputs, and inputs are where you are weakest.
The numbers are too small to matter and too messy to track
A typical solo owner pays for two or three AI subscriptions at around $20 each. Spread across ten clients, that is a few dollars per client per month. Tracking it accurately takes more time than it recovers, and an invoice line of $4.30 looks petty rather than professional.
It anchors your price to a cost that is falling
AI prices for a given level of capability have been dropping steadily. If you bill AI as a cost item, you train clients to expect your fees to fall with it. If you price on the value of the outcome, the efficiency gains stay with you, which is the whole point of adopting the tools.
The exceptions where passing costs through is right
Being skeptical of itemizing does not mean never doing it. There are three situations where a pass-through charge is fair and expected.
- Heavy usage-based generation for one client. If a client wants 40 AI product videos or a large batch of generated images, those credits are a direct, project-specific expense, just like stock photos or printing. Quote them separately.
- Tools the client asked for. If a client insists you use a specific paid platform you would not otherwise subscribe to, its cost belongs to them.
- Ongoing automations you run on their behalf. If you set up and host an automation that runs on a per-task meter, the running cost should sit in a monthly retainer, ideally with a clear cap. Our breakdown of what one AI step really costs helps you estimate it.
The common thread: pass through costs that scale with one client’s demands. Absorb costs that are part of how you work for everyone.
A pricing strategy for 2027 in four moves
Move 1: Fold your baseline AI costs into your rates
Add up every AI subscription you pay for. (If you have not done this recently, our 60-minute year-end AI audit will help.) Divide the annual total by the number of billable hours or projects you expect next year. For most solo owners that comes out to well under $5 per project. Build it into your January rate like any other overhead. If you are already planning a rise, our 90-minute workflow for raising prices in January walks through the numbers and the announcement.
Move 2: Add a pass-through clause, but only for heavy usage
Add one sentence to your proposals and contract: something like “Third-party generation costs above $50 per project (for example, large batches of AI images or video) are quoted in advance and billed at cost.” This protects you from the rare expensive project without putting AI on every invoice.
Move 3: Track your own AI time savings, privately
You do not need enterprise tagging. Keep a simple note per project: roughly how long the work would have taken before AI and how long it took now. After three months, you will know your real efficiency gain, and that number, not your subscription cost, should drive your pricing decisions. If AI saves you 30% of the time on a project type, consider moving that work to a fixed price so the saving becomes your margin.
Move 4: Be open about using AI, quiet about its cost
Transparency about whether and how you use AI builds trust, and in some industries it is becoming expected. Transparency about what AI costs you rarely helps anyone. Keep the first in your disclosure policy (see our guide to writing an AI disclosure clause) and keep the second in your own books.
What could change this advice
To stay honest, here is what would make me revise this view. If AI costs per project rise sharply (for example, if you shift into heavy video or agent work where a single task can cost real money), pass-through becomes more important. If your industry develops a norm of itemized AI disclosure, as some legal and agency clients may push for, you will need a clean way to report it. And if clients start asking for AI-free work at a premium, you will want your time-tracking notes from Move 3 to price it.
The broader trend is that solo founders are using AI to take on work that used to need a team, a shift Fortune reported on earlier this year. The businesses that do well will be the ones that price that leverage as value delivered, not as software resold.
The short version for your next proposal
Build normal AI subscriptions into your rate. Quote heavy, client-specific generation separately and at cost. Track your time savings and let them inform fixed prices. Disclose your use of AI, not your bill. How are you handling AI costs with your clients right now? We would like to hear in the comments.
