Hiring your first employee: the real cost and essential steps
The real cost of hiring goes far beyond the net salary shown to the candidate, and this is precisely what many business owners underestimate when recruiting their first employee. This first hire turns a one-person business into a real employer, with new legal obligations and a direct, lasting impact on cash flow. Too often focused on the net pay offered, business owners fail to factor in all the charges and peripheral costs that make up the real cost of hiring. This step, often experienced as a psychological milestone as much as an administrative one, deserves careful preparation.
The real cost of hiring: well beyond the gross salary
The gross salary stated in the contract is only part of the total expense borne by the business. On top of this come employer social security contributions, which generally represent between 25% and 42% of gross salary depending on the sector, the size of the business and any applicable exemptions, in particular the general reduction in employer contributions on low salaries, known as the Fillon reduction. A gross salary of 2,500 euros a month can therefore represent a total employer cost of between 3,200 and 3,500 euros a month, depending on the collective agreement and the exemptions available.
You also need to include the indirect costs that are too often left out of the budget: company health insurance, mandatory for every employee since complementary health cover became universal, occupational health services, workstation equipment (IT hardware, software, furniture), mandatory training costs depending on the job, and possibly the recruitment costs themselves if the business uses a paid job ad or a recruitment agency. It is precisely these peripheral costs that most often derail the budget for a first hire.
The essential administrative steps before and after hiring
Before the employee starts, the employer must submit the pre-hiring declaration (DPAE) to URSSAF in the days before the employee arrives. This formality, mandatory for any first hire, automatically triggers registration with certain social security bodies. The employer must then join a supplementary pension fund and take out a company health insurance contract that meets the minimum cover required by law.
The employment contract must be drafted in line with the collective agreement that applies to the business’s activity, which often sets minimum wages above the SMIC (French minimum wage), specific probation period rules and job classification grids. Ignoring the applicable collective agreement is a common mistake among first-time employers, and it exposes them to the risk of an employment tribunal claim in the event of a dispute with the employee.
Once the employee is in post, the business must display the mandatory employment law notices, keep a staff register and organise monthly payroll: issuing the payslip, submitting the nominative social declaration (DSN) to the social security bodies every month, and paying the corresponding contributions on time.
The impact of a first hire on the business’s cash flow
A first hire permanently changes the business’s cash flow profile: the net salary and social charges must be paid every month, regardless of the actual level of activity or the pace of client payments. Unlike an external contractor whose cost can vary with assignments, an employee represents a fixed, recurring cost that commits the business over time.
It is strongly recommended to build up a cash reserve equivalent to two or three months of fully loaded salary before making a first hire, so you can absorb a temporary dip in activity or a late client payment without jeopardising salary payments, which remain an unavoidable legal obligation even in difficult times.
Getting support to secure this key step
Between payroll management, social security reporting obligations and cash flow tracking, a first hire brings several sources of complexity for a business owner who has until now run the business alone or with external contractors. Relying on a financial management tool lets you precisely simulate the impact of the hire on your cash flow before committing, then secure the monthly follow-up once the employee is in post. This is exactly the kind of support Dirigeoo offers its users, to get through this milestone without any nasty surprises.
