AI agent vs hiring

Only part of a role is repeatable, and that part is the whole decision. This is a scoping exercise, not a shopping one.

Deciding between an AI agent and a hire is not a pricing question. Work out which hours in the role are genuinely repeatable, cost the hire the way an accountant would, and be specific about what stays human. Once the scope is honest, the cost comparison answers itself.

A senior hire and an AI agent can carry some of the same repeatable work, so the two get compared. The comparison usually goes wrong immediately, because a salary gets set against a subscription price and neither figure is the real one. The useful version of this decision is narrower and more concrete: which specific hours are repeatable, what does the hire truly cost once loaded, and what will still need a person afterward. That is a scoping exercise, not a shopping one.

Why the usual comparison misleads

  • Most of the debate treats the role as one indivisible thing, when only part of it is repeatable. The repeatable part is the only part an agent can carry, and nobody settles the argument without scoping that first.
  • Base salary is not the cost of an employee. Wages and salary are 69.9 percent of total employer compensation in private industry, so the loaded figure is roughly 1.4 times the offer letter, every year, with recruiting on top (U.S. Bureau of Labor Statistics, March 2026).
  • Vendor comparisons lean on industry-average salary and revenue-per-employee benchmarks, but those vary so widely by sector that any ratio built on them describes the chosen average rather than your business.
  • The measured productivity effect is real and smaller than sales material implies: 15 percent on average among 5,172 customer-support agents at one firm, concentrated in the least experienced staff (Quarterly Journal of Economics, 2025).
  • Scope drift is the quiet failure. An agent pointed at work that stopped being repeatable keeps costing money without anyone noticing it stopped earning.

How EP frames the decision

1

Separate the repeatable hours from the role

Go through the job as it is actually performed and mark the work that follows a stable pattern: the drafting, the lookups, the routing, the data entry. That slice is the only candidate for an agent. Everything else stays with a person, and saying so at the start is what keeps the rest of the analysis honest.

2

Cost the hire the way an accountant would

Take your real salary band, not an industry average. Multiply by roughly 1.4 to reach loaded cost, add recruiting, and treat it as a recurring yearly line rather than a one-time decision. This is arithmetic you run on your own numbers, which is the only version of it worth trusting.

3

Put a published price on the other side

Our Agents tier is $10,000 to set up and $500 a month per agent after that, which is $6,000 a year ongoing, with additional agents at $5,000 each. Load it the same way you loaded the salary and compare the two yearly lines directly. A fixed, checkable number belongs on this side of the comparison instead of a projection you would have to take on faith.

4

Decide on scope, then implement, then keep improving

An agent that is bought and left alone becomes a cancelled line item. The work that makes the arithmetic real is wiring it into the actual workflow, defining who owns it, and continuing to improve it after launch. That ongoing ownership is the deciding variable, not the price.

How we keep the scope honest after launch

The cost comparison is the part everyone runs. What determines whether the decision still looks right a year later is whether the scope stayed true, and that needs checking rather than assuming.

The agent's scope is written down as a list of tasks, not a job title, so "is this working" has a checkable answer instead of a vibe.
If the repeatable slice turns out to be smaller than we scoped, that is a finding we report, not a reason to quietly broaden the agent until it justifies its price.
Scope is reviewed as the business changes. Work that was repeatable last year may not be, and an agent aimed at the wrong slice stops earning its cost without announcing it.
You still hire. Scoping first changes what the job posting says and what you screen for, it does not remove the role.

Common questions

How much does an AI agent cost?

Our Agents tier is $10,000 to set up and $500 a month per agent after that, which comes to $6,000 a year ongoing. Additional agents are $5,000 each. Those prices are published on our services page rather than quoted per deal, so you can compare them against your own loaded salary figure before you ever talk to us.

Is an AI agent cheaper than hiring someone?

For the repeatable slice of a role, in nearly every band we have seen, yes. Base salary understates a hire by roughly 1.4 times once benefits are counted, and recruiting sits on top of that. Run those against $10,000 to set up and $6,000 a year ongoing, using your own salary band rather than an industry average. The more useful question is not whether it is cheaper but how much of the role is genuinely repeatable, because that is what decides whether the saving is real.

Can an AI agent actually replace a role?

No, and we would not scope one that way. An agent carries the repeatable hours inside a role: the drafting, the lookups, the routing. Judgment, relationships, escalation, and accountability stay with a person. The realistic outcome is a role that stops spending its week on boilerplate, not a headcount line that disappears.

How long before it is doing useful work?

The Agents tier is a fixed-scope setup sprint that ends with the agent live in your stack and handed to your team running, rather than an open-ended program. The honest variable is not our build time, it is how quickly you can answer the scoping question: which hours are repeatable and who owns the agent afterward. Engagements that arrive with that already settled move considerably faster.

How much productivity gain should we expect?

The best measured figure we are willing to quote is a 15 percent average lift, from a peer-reviewed study of 5,172 customer-support agents at a single firm (Brynjolfsson, Li and Raymond, Quarterly Journal of Economics, 2025). That average hides real variation: the same study found the largest gains among less experienced workers, who improved in both speed and quality, while the most experienced saw very little change. Larger figures circulate widely and are typically illustrative rather than measured.

What happens if it does not work out?

It is a fair question given that 42 percent of companies scrapped most of their AI initiatives in S&P Global's 2025 survey, up from 17 percent the year before. The failure is rarely the model. It is usually that the agent was bought rather than implemented, and then owned by nobody. We scope narrowly, wire into the real workflow, and keep improving after launch, because that is the variable those failures have in common. The Agents tier also carries a written setup guarantee, which is on the services page.

Should we do this instead of hiring, or before hiring?

Most often before, and not instead. Scoping the repeatable work first tells you what the open role should actually be. Handling the boilerplate separately tends to change the job description toward judgment and away from throughput, which is usually the hire you wanted in the first place.
