What an AI Employee Really Costs: Subscription, Custom Build, or Hire

A subscription AI employee lists at $50 to $2,000 a month, but once you add credit top-ups and the staff hours spent supervising it, a realistic first year runs about $6,600 to $39,000. A custom-built AI employee costs from $3,500 one-time plus modest running costs, landing around $6,700 to $27,000 in year one and well under that in year two. Hiring a coordinator to do the same work costs $56,000 to $75,000 a year, loaded, every year.

Those are the honest numbers, and almost nobody publishes them. Search for AI employee pricing and you get vendor price lists: monthly tiers, credit bundles, a free trial. Useful, but a price list is not a cost. The sticker is the smallest line on the bill in every one of the three paths, and what actually decides the 12-month number is the stuff that never appears on a pricing page: who checks the output, what happens when the credits run out, and whether the thing talks to the system your business actually runs on.

This is the full accounting for all three paths, the hidden costs on each, a worked 12-month comparison, and the cases where each option is the right buy, including the ones where you should skip the software and hire.

Path one: the subscription AI employee

The SaaS end of the market sells AI employees the way you would buy any other app: pick a persona, connect your accounts, pay monthly. The list prices are real and they are low. A few examples from the vendors' own pricing pages, as of this writing: Sintra lists its bundle of AI helpers from $48.50 a month on a monthly plan, with a monthly credit allowance; Lindy lists team plans from $29.99 per seat with a shared credit pool, pausing work when credits run out, with top-ups at $10 per 1,000 credits; and Salesforce lists Agentforce at $2 per conversation or Flex Credits that work out to about $0.10 per standard action. Those are vendor figures and they change often, but the pattern holds across the category: roughly $50 to $2,000 a month for small-business tools, with usage metered on top.

Sales-focused AI SDR platforms sit higher. One July 2026 breakdown from Modern Inbound, a lead-generation agency, puts a realistic annual cost for an AI SDR platform at $30,000 to $96,000 once you include data subscriptions, sending infrastructure, and 3 to 5 hours a week of human oversight. Treat that as an industry estimate, not an audited number, but notice what it includes. The oversight hours are in there, and they should be in yours too.

That is the line that turns a $99 tool into a five-figure one. Somebody on your team reads what the AI employee drafted, checks the records it updated, and fixes what it got wrong. At 3 to 5 hours a week and a loaded internal rate of about $40 an hour, that is $6,000 to $10,000 a year of salaried time, and it does not shrink much, because the product was built for the average company and your exceptions are not average.

Path two: the custom-built AI employee

A custom build inverts the cost structure. You pay once, up front, for an AI employee designed around how the role actually runs in your business, wired into the systems you already use, with explicit rules for what it does alone and what it routes to a human. Then you pay to run it.

The build. A bounded build, one role's highest-payback workflows wired into one or two systems, starts at $3,500 as a fixed fee. A fuller role with thornier integrations commonly lands at several times that; for the worked example below I use $3,500 to $15,000 for a single coordinator-class role. Multi-role programs scale with company size and are quoted per engagement. The point of a fixed fee is that the number is known before work starts, and a well-scoped AI employee engagement gives you that number with the reasoning attached.

Running costs. Model usage, meaning the API calls to whichever language model does the reading and drafting, plus hosting, queues, and storage. For one role's worth of work this is typically $100 to $500 a month, so $1,200 to $6,000 a year. It scales with volume, which is the right way for it to scale.

People time. A custom build still needs a human, but in a different place. Because it is designed around your exceptions, it handles the routine cases on its own and routes the rest to a review queue. Expect 1 to 3 hours a week on that queue once the system has calibrated, so 50 to 150 hours a year.

Upkeep. Your systems will change. A vendor deprecates an API, you switch CRMs, a new product line adds a new exception. Each of those is a small change to the build, handled either by your own engineer or by a management retainer scoped on the same call as the build. Budget for it; it is real, and it is far smaller than the build.

Path three: hire the person

A US coordinator-class salary runs roughly $45,000 to $60,000. The employer cost is higher. Bureau of Labor Statistics data for June 2026 put benefits at 30 percent of total compensation costs in private industry. Part of that is paid leave, which a salary already covers, so the conservative rule of thumb is about 25 percent on top of salary for payroll taxes, insurance, retirement, and the rest. That makes the seat $56,250 to $75,000 a year, before recruiting fees, equipment, and the manager's time, and it recurs every year with raises.

That number buys something software does not: judgment, relationships, accountability. Which is why the useful question is rarely AI or person, and usually which share of the role is repeatable. We wrote a separate guide on splitting a role before you fill the seat; this article is the cost side of that decision.

The hidden costs nobody prices in

Every path has costs that are not on the quote. These are the ones that move the 12-month number.

Oversight hours. The single largest hidden cost on the subscription path, and present on the custom path too. Ask any vendor how many hours a week their typical customer spends reviewing output. If they do not know, budget 3 to 5.

Overages and top-ups. Credit-metered pricing is built so that the plan you start on is the plan you outgrow. Credits that do not roll over, per-action charges, and per-conversation charges all mean the bill scales with success. Model the month where volume doubles, not the average month.

Integration. Subscription tools connect well to the popular apps: Gmail, Slack, HubSpot. If your business runs on an industry system, a legacy database, or a spreadsheet with twelve tabs, somebody pays to bridge the gap: your team by hand, a middleware subscription, or a consultant. A custom build prices this in up front, because wiring into your systems is the job.

Error cleanup. An AI employee that sends the wrong email, updates the wrong record, or misreads an invoice creates work, and sometimes a client conversation. The cost depends on whether mistakes land in a review queue or in the world. Design decides that, not the model.

Lock-in. On a subscription, your prompts, workflows, and the history of what the AI employee learned about your business live inside the vendor's product. Leaving means rebuilding. On a custom build you own the code, the configuration, and the documentation.

Vendor churn. This category is young and crowded. Vendors reprice, change credit math, pivot to enterprise, get acquired, or shut down. Any of those can force a migration you did not plan for, which is a switching cost you pay on their schedule.

Security review. An AI employee reads your email, your CRM, sometimes your books. Somebody should check what access it holds and where your data goes. That work is the subject of its own guide: how to secure an AI employee before it touches your data.

A worked 12-month comparison

Here is one coordinator-class workload priced three ways. The assumptions, stated plainly so you can swap in your own: the subscription runs $50 to $2,000 a month with up to $3,000 a year in top-ups and 3 to 5 hours a week of oversight; the custom build costs $3,500 to $15,000 once, $100 to $500 a month to run, and 1 to 3 hours a week of exception review; the hire is a $45,000 to $60,000 salary plus 25 percent overhead. Internal time is valued at $40 an hour. Recruiting and management time are left out, which flatters the hire.

Three things stand out. First, at the low end the subscription and the custom build cost about the same in year one; the difference is what you get for it, a generic tool or a system designed around your process that you own. Second, year two is where the paths split: the build fee does not recur, the subscription and its oversight hours do. Third, the hire costs several times either software path, but it also buys the judgment share of the role that neither software path covers. In practice the winning answer is often a build plus a smaller human role.

When each option wins

The subscription wins when the task is generic and matches the product's shape exactly, your stack is the popular apps the product already supports, the volume is low, the data is not sensitive, and you want to try something this week. A $50 tool that does one standard job well is a fine buy. Start there if that describes you.

The custom build wins when the process is specific to your business, the work touches your system of record, the volume is high enough that per-action pricing hurts, real money or client data is involved, or you intend to run it for more than a year. It also wins when the subscription keeps stalling on your exceptions and a person quietly takes the work back, which is the most common reason companies come to us after trying a bot.

Hiring wins when the role is mostly relationships, taste, and negotiation; when the repeatable work adds up to a few hours a week, too little to pay back any build; when the process changes every month; or when nobody internal will own the review queue. No owner, no build. That rule has no exceptions, and it is cheaper to learn it before you spend than after.

For context on where the numbers come from on our side: I have been fractional CTO of a New York promotions agency since 2017, where I built and still run an OCR receipt-promotions platform that has processed roughly 100,000 receipts across 3 to 6 national promotions a year for brands like Unilever, Knorr, and Fandango. It is an AI employee in all but name, and its cost profile is the one described above: built once, cheap to run, a human on the exceptions, and upkeep when the world changes. The case study is here.

Get a real number for your role

You can run most of this math yourself. List the repeatable tasks in the role, estimate hours per week, decide who owns the review queue, and price the three paths with your own numbers using the table above. If the custom column looks right, bring the role to a call. We will tell you what is buildable, what the fixed fee would be, what it costs to run, and what should stay human. If a $50 subscription or a part-time hire is the better answer, we will say that too.

Questions buyers ask

How much does an AI employee cost per month?

Subscription AI employees list at roughly $50 to $2,000 a month, with usage credits on top. That sticker is the smallest part of the bill: add the staff hours spent supervising the tool and any top-ups, and a realistic first year for a small-business subscription runs about $6,600 to $39,000. A custom build has no subscription: you pay once for the build, from $3,500, then model usage and hosting, typically $100 to $500 a month.

Is a custom AI employee cheaper than a subscription?

In year one they often cost about the same. From year two the custom build is usually cheaper, because the build fee is paid once while the subscription and its oversight hours repeat every year. The bigger difference is what you get: a custom build is designed around your process and your systems, and you own it, while a subscription does one job its way and stays on the vendor's platform.

What are the hidden costs of an AI employee?

Six come up repeatedly: the staff hours spent reviewing its output, credit overages and top-ups, integration with systems the product does not support out of the box, cleaning up its mistakes, lock-in to the vendor's platform, and the vendor itself changing price, pivoting, or shutting down. A custom build has its own: running costs, upkeep when your systems change, and the need for an internal owner.

How much does an AI employee cost compared to hiring?

A US coordinator-class hire at $45,000 to $60,000 in salary costs about $56,000 to $75,000 a year once roughly 25 percent of overhead is added, every year. A bounded custom AI employee lands around $6,700 to $27,000 in its first year all-in and less after that. The AI employee covers the repeatable share of the role, not the judgment share, so the honest comparison is usually a build plus a smaller human role, not a build instead of a person.

When should I just hire a person instead?

When the role is mostly relationships, taste, and negotiation; when the repeatable work adds up to only a few hours a week; when the process changes every month; or when nobody internal will own reviewing the AI's exceptions. In those cases a person, possibly part-time, is the better buy.
