Private security company: the key role of the accountant (CNAPS, payroll, 2026)

A specialised accountant for a private security company masters two constraints unique to the trade: the CNAPS regulation (operating authorisation, director approval, professional cards) and an intensive payroll under the prevention and security collective agreement (IDCC 1351), with night premiums and panier and habillage allowances. The value lies in securing that payroll and protecting the margin.

Private security is not an ordinary commercial activity: it falls under Book VI of the internal security code (CSI) and the oversight of the CNAPS (National council for private security activities). The activities covered by article L611-1 include human surveillance, surveillance through electronic security systems, the guarding of movable and immovable property and the safety of persons within those premises.

Three distinct and cumulative authorisations govern the activity:

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." Renewal must be requested at least three months before expiry. The individual entrepreneur who works on the ground himself holds all three authorisations at once.

When we support the creation of a private security company, the timeline is not limited to filing the articles of association. The operating authorisation and the director approval condition the actual start of the business: without them, no service can be billed legally. We therefore build the cash-flow plan around this administrative lead time, not around the registration date alone.

The choice of legal form (SASU, SARL, multi-partner company) must also account for the fact that each partner may be subject to approval. A capital split decided without anticipating the partners' approval can block the authorisation. This is a point we check upstream.

A guarding company runs around the clock: day and night shifts, weekends, public holidays. The collective agreement for prevention and security companies (IDCC 1351) provides, among other things, a night-shift premium over the 9 p.m. - 6 a.m. window, as well as a panier allowance and an habillage allowance. These elements are calculated agent by agent, on highly variable shift schedules, with overtime and working-time modulation.

In practice, this generates a high volume of payroll variables every month. With large headcounts, often at the agreement minimum, the wage bill becomes the number-one cost item and the margin remains thin. The slightest error on a premium, multiplied by the number of agents and payslips, quickly turns into labour-court and URSSAF exposure.

In this sector, the value of a specialised accountant is not measured by bookkeeping but by the reliability of payroll and the steering of margin per contract. The selling price of an hour of service is often negotiated at the tightest level: it is the correctly calculated premiums, allowances and overtime that make the difference between a profitable assignment and a loss-making one.

The underestimated risk: a poorly configured night premium or a forgotten contractual allowance goes unnoticed as long as no agent disputes it. The day a URSSAF audit or a labour court looks at the file, the back claim covers all the affected payslips, over several years. A payroll setup aligned with IDCC 1351 from the outset costs far less than fixing it later.

A growing human-surveillance company wins several sites to cover 24/7. Schedules multiply, night shifts pile up and payroll is processed manually. Over the months, night premiums are applied inconsistently from one agent to another. The firm's role here is to make the payroll setup reliable against the agreement, to produce margin indicators per contract, and to clarify, contract by contract, which ones are profitable and which must be renegotiated.

• Validity and expiry of director approvals and professional cards (renewal three months in advance)
• Payroll setup compliant with IDCC 1351 (night premiums, panier, habillage)
• Overtime, modulation and shift schedules correctly reported in payroll
• Tracking of the wage bill and margin per contract, not only at the overall level
• Cash-flow anticipation over the lead time to obtain the operating authorisation
