Chartered accountant for private security and guarding companies

An accountant for a security company knows the two constraints the sector combines: CNAPS compliance (the three distinct titles, namely the operating authorisation, the director approval and the agents' professional card) and payroll under the prevention and security collective agreement, one of the most technical there is, with its night, weekend and public-holiday premiums.

Private security and guarding form a sector apart. The business can only start with strict administrative authorisations, it runs 24 hours a day, and its profitability rests on a few margin points over a considerable payroll cost. Standard bookkeeping, designed for ordinary SMEs, misses the essentials. Our firm approaches your company through what defines it: the CNAPS framework and the contractual payroll.

Private security activities are governed by Book VI of the internal security code and supervised by CNAPS (the national council for private security activities). Article L611-1 of the code defines the scope covered: human surveillance, surveillance through electronic security systems, guarding of movable and immovable property, and safety of persons inside those buildings.

To operate lawfully, your company must hold three distinct and cumulative titles:

Article L612-6 is unambiguous: no one may carry out, on an individual basis, an activity mentioned in article L. 611-1, nor direct, manage or be a partner of a legal entity carrying out that activity, unless they hold an approval. In other words, director approval conditions the very right to run the company. The sole trader working in the field holds all three titles at once: director approval, operating authorisation and professional card.

The most underestimated point of vigilance concerns renewal. The director approval and the professional card are valid for 5 years, and renewal must be requested at least 3 months before expiry. A title allowed to lapse can interrupt your right to operate and, in turn, weaken ongoing client contracts. In your permanent file, we keep a schedule of these titles and alert you in good time: for us, it is a compliance point as important as your tax obligations.

Once CNAPS compliance is achieved, the heart of management shifts to payroll. Guarding companies fall under the national collective agreement for prevention and security companies, IDCC 1351. It is one of the most demanding payrolls in France, because the activity runs continuously.

Your agents work day and night shifts, weekends and public holidays. The agreement provides in particular for a night-hours premium over the 9 p.m. to 6 a.m. window, plus a meal allowance and a clothing allowance. Each of these items must appear correctly on the payslip, agent by agent, shift by shift.

Our reading. In a security company, payroll is a flow of variables: shift schedules, overtime, working-time modulation, multiple premiums that stack up. The volume of data to process per agent is very high, and every error has a cost. A forgotten night premium is a labour-court risk; a miscalculated premium, a risk of URSSAF reassessment. Our job is to industrialise this collection without sacrificing accuracy.

In practice, we structure the upstream collection of payroll variables (from your schedules or your activity-management software) so that each shift is correctly valued. The aim is to apply every premium provided by the agreement, over a large number of payslips, without error and on time.

Private security is a structurally thin-margin sector. Headcount is large and largely positioned at the contractual minimum; payroll and the related charges absorb most of the revenue. Here, the number-one cost item, by far, is staff.

This changes how the company is managed. In a retail shop, you watch purchases; in a security company, you watch the gap between the hours billed to the client and the hours actually paid to the agent, premiums included. A few points of discrepancy on one contract, multiplied by dozens of agents and twelve months, tip a site from profit to loss.

We therefore build a monthly dashboard that links:

• the hourly rate billed to the client, contract by contract;
• paid hours and their premiums (night, weekend, public holidays);
• non-productive hours (travel, training, inter-contract gaps);
• the net margin per site and per contract.

This tool makes unprofitable shifts visible before they settle in for good.

Take a situation we regularly encounter, without naming any real client. A human-surveillance company grows fast: it goes from a few agents to several dozen by signing new sites. The director feels revenue is progressing well, but cash flow stays tight and he cannot say which contracts make money.

On analysis, two phenomena combine. First, some contracts were signed at an hourly rate that does not cover, once night and weekend premiums are added, the real cost of the agent. Second, non-productive hours (replacements, travel between sites) were never re-billed or even quantified. The result: two or three sites in fact carry the whole group, while several others run at a loss without anyone having identified it.

The clean-up runs through a margin-by-contract dashboard, a review of hourly rates on loss-making sites at renewal, and a tightening of payroll variables. In parallel, we check that the CNAPS schedule is up to date, because strong headcount growth also multiplies the professional cards to monitor.

The most frequent sticking points in security-company files:

• Neglecting the CNAPS title calendar. A director approval or a professional card allowed to lapse, for want of monitoring anticipated at least 3 months before expiry. This is the most serious risk because it touches the very right to operate.
• Underestimating contractual premiums. Night, weekend or public-holiday hours poorly valued on payslips, generating labour-court litigation and a risk of URSSAF reassessment.
• Confusing revenue with profitability. Signing contracts at an hourly rate that does not cover the real cost of the agent once premiums are included.
• Ignoring non-productive hours. Travel, replacements, training and inter-contract gaps that weigh on payroll without being quantified or re-billed.
• Managing once a year, at year-end. In a thin-margin sector, waiting for the closing to discover a loss-making site means discovering a structural drift far too late.
