AI agent or new hire: the math to run before you choose

A week gets buried, the follow-ups fall behind, and the question comes up: should we hire somebody? That is rarely the right first question. The right one is what exactly is overflowing, and does it call for human judgment.

The two do not solve the same problem

A hire adds judgment, relationships, presence. An agent adds capacity on what repeats. Put a person on repetitive work and you are paying for judgment to do data entry. Put an agent on work that means reading a new situation every time and it will hand the file back untouched, and you will have paid for nothing.

Our rule is plain: the agent replaces nobody, it makes the next hire unnecessary for now. Your current team keeps deciding; it stops retyping.

The calculation, with your own numbers

Before comparing prices, count what the task costs you today. Three figures are enough:

• The real hours. How many per week, on whom, at what loaded hourly rate. Not the gross salary: the full cost, payroll taxes and vacation included.
• The cost of the delay. A request answered Monday instead of Saturday, a quote that goes out three days late: how many contracts that costs you a year. It is usually the biggest line, and the only one nobody books.
• The ceiling. The volume at which your current person breaks. That figure decides whether you are buying hours or buying capacity that climbs without another hire.

Once those three numbers are written down, the comparison becomes a subtraction rather than a hunch. And often the answer is neither one nor the other for now: the volume does not justify it yet.

When hiring is still the right call

There are cases where automating is the wrong answer, and it is better said before invoicing you:

• The work is different every time and rests on trade judgment. A site visit, a negotiation, a complex diagnosis.
• Your way of working changes every month. There is no settled way of proceeding yet, so there is nothing settled to hand over.
• The volume is low. A handful of requests a month gets handled by hand for less than any tool costs.

One concrete case: pricing quotes

This is the sharpest example, because the task repeats but the final decision does not. Taking the request, reading what is being asked, measuring the work, applying the price grid, writing the quote: all of that repeats. Deciding to accept the contract, adjusting for a difficult client, sensing that a job is going to go badly: none of that repeats.

That is exactly the line Le Métreur follows: it prepares the priced quote as a draft, you read it, you send it. The estimator is not replaced. The next estimator is not hired.

The same logic applies to requests arriving at night and on weekends, with an agent that takes, qualifies and follows up, or to fixed rule work calling for no judgment at all, which belongs to process automation.

Where to start

Take the task that cost you the most in delay last month, and run the three figure calculation above. If you want somebody to run it with you and tell you plainly when hiring is the better call, that is what the diagnostic does: it puts a number on what each job would return at your place before you commit a budget.
