What it costs

What an employee really costs

A post never costs the salary announced. Between gross pay, employer contributions, equipment, software, floor space and supervision time, the amount actually committed is appreciably higher — and it is committed for months, whatever the order book says. It is that difference, not the salary itself, that blocks most hires in small companies.

1. Working out the real cost of a post

Before any comparison, you need the exact figure — yours, not an average. It comes in four layers, and most owners stop at the first.

Gross salary. The only figure discussed at interview, and the only one everybody knows.
Employer contributions. They are added to the gross and vary widely by country, pay level and applicable relief. Do not take any percentage read online: ask your accountant or payroll software for the exact employer cost, for the precise salary you have in mind.
Equipment and licences. Computer, phone, furniture, floor space if you have premises, and above all software subscriptions — every post adds a licence on every tool in the company, every month.
Other people's time. Recruiting, training, supervising, correcting, explaining again. That cost appears on no accounting line, it is paid in hours of management, and it is heaviest in the first six months.

Do the sum for one specific post before reading on. What follows is only of interest applied to your own figure.

2. The hidden cost: commitment over time

The amount matters less than its rigidity. A post is a fixed cost: it falls due every month whether demand is strong or nil, and it cannot be reduced from one quarter to the next without serious human and legal consequences.

That is what makes the judgement hard for a young or seasonal business. The work exists — the chasing does not go out, the site is not built, nobody answers Saturday's enquiries — but it does not regularly fill a full-time post, and a fixed cost is exactly what you cannot commit to an irregular need.

The outcome is almost always the same, and it is worse than the cost that was avoided: nobody is hired, and the work is not done. It does not go away for all that — it piles up, quietly, until it costs a customer.

3. The wrong question, and the right one

The wrong question is “can I afford this salary”. It leads to comparing an amount with a bank balance, and the answer is no almost every time.

The right question is: “does this work justify a whole post?” It changes everything, because the answer is often no even though the work is indispensable. An owner who needs four hours of customer chasing a week, two hours of posting and a daily watch does not need an employee: they need those three things done.

Once the question is put that way, three routes open instead of one — hire, outsource, or delegate to a system. The first is the heaviest and the most rigid; that is not a reason to rule it out, it is a reason to choose it only for what deserves it.

4. The work that never justifies a post

Some tasks recur in every company, are indispensable, and will never fill a full-time post on their own. They are the ones that weigh on the owner, precisely because none reaches the threshold that would justify a hire.

Chasing. Quotes without a reply, overdue invoices, dormant customers. A few minutes each, never done at the right moment, and directly tied to cash flow.
Being present online. Posting regularly, keeping up search visibility, keeping the site current. Work whose absence goes unnoticed — until the day nobody finds you any more.
First-line response. Sorting incoming requests, answering routine questions, routing to the right person. Indispensable, and impossible for one person to cover continuously.
Keeping records. An up-to-date customer file, minutes, filing, preparing documents for the accountant. No particular talent required, only consistency — the opposite of what a busy human can guarantee.

None of these tasks justifies a hire. All of them together cost the owner the equivalent of a day a week — the day not spent selling.

5. What companies without a budget do

Faced with that wall, three solutions existed. Each has a known flaw, and it is only honest to name them.

Doing it all yourself. Free in appearance, and the most expensive in fact: the owner's time is the company's scarcest resource. What is done in the evening is done late, badly, or not at all.
Outsourcing to an agency. Effective and expensive. A monthly retainer for SEO, a quote for a website, another for an app, a package for posting. Each service is a contract, and the total often exceeds the post you could not afford.
Conventional software. It files and it calculates, but it does not act: it tells you which invoices are overdue, it does not chase them. The work still has to be done, only better listed.

A fourth way now exists: entrusting these tasks to autonomous AI agents, which receive an objective, have the tools they need and account for what they have done. It is not one more piece of software to fill in: it is work carried out, with a readable trail.

6. What can be delegated to agents, and what cannot

On nullbot, the tasks above are covered by agents to whom the work is described in plain language, without writing code. Three of them replace services normally billed by quote:

The website. It is described in conversation: the agent proposes variants, produces the pages, finds the images, opens a customer area, connects payment, reserves the domain name and puts it online — with a version history and a way back if the result displeases.
The mobile app. Same principle, through to trying it in an iPhone and Android simulator, then publishing on the App Store and Google Play.
Search visibility. Site audit, position tracking by keyword and by country, checking how readable the site is to AI models — the work an agency bills monthly, kept up continuously.

What cannot be delegated is not what is difficult, it is what commits the company: signing, hiring, paying, granting a discount, ending a contract. Those acts go through human approval requested before execution, and each agent works under a spending allowance it cannot exceed. A system that does not provide both is a system you cannot steer — and spending you do not cap becomes exactly the problem you were trying to escape.

7. Frequently asked questions

How do you work out the real cost of an employee?

By adding up four layers: gross salary, employer contributions, equipment and software licences, then the time other team members spend supervising. Contribution rates depend on the country, the salary level and any applicable relief: the only reliable figure is the one your accountant or payroll software gives for the precise post you have in mind.

Can AI agents replace an employee?

That is not the right way to put the question, and the honest answer is no for an entire job. Most small companies, however, do not have a post to replace: they have a set of indispensable tasks that never reach the threshold of a hire, and that nobody does. That is the work that can be delegated.

Is it cheaper than an agency?

The nature of the expense differs more than its amount, and that is what matters to cash flow. An agency bills a service per contract, often with a commitment period. A software subscription can be cancelled, and you see what each task cost, one by one. No figure for savings can be promised here: it depends entirely on what you delegate and on the volume.

Do I need to know how to code to use it?

No. The work is described in plain language, as you would explain it to someone joining: what is expected, within what limits, and what must be raised before acting. The difficulty is not technical, it is stating a rule clearly — and many companies discover, in delegating, that they had never written down their own criteria.

How can I be sure the bill will not run away?

By an enforceable ceiling, not by trust. Each agent has a spending allowance reserved before the model is called: allowance spent, the call does not happen. Overspending is made impossible, not merely unlikely — and the cost of each task is visible, which lets you decide whether it was worth delegating.
