In a service SME or start-up, performance largely depends on the effective allocation of human resources. Structuring the workforce by the company's main functions is a key indicator for monitoring the balance between development, management, and support.
The mission of the external CFO is to provide this cross-functional vision and help adjust the allocation of resources based on the company's maturity, its industry, and its growth objectives.
1. Identify the main functions of the company
Generally, we distinguish four functional families in service SMEs:
- Tech / Product / R&D : development of platforms, tools or digital solutions.
- Sales / Business / Development : prospecting, sales, commercial management, partnerships.
- Marketing / Communication : lead acquisition, brand awareness, content, positioning.
- Support / HR / Finance / Legal : administration, talent management, financial monitoring, compliance.
Clearly identifying these functions allows for a clear view of workforce mobilization, anticipating imbalances and preparing for recruitment or outsourcing.
2. Indicative distribution of staff in a service SME
Here is an indicative grid of distribution observed in growing SMEs:
| Function | Estimated share of staff |
|---|---|
| Tech / Product / R&D | 0 to 10 % |
| Sales / Business / Development | 40 to 55 % |
| Marketing | 10 to 20 % |
| Support / HR / Finance | 10 to 20 % |
These ratios are market benchmarks, mais doivent être adaptés à chaque entreprise selon son modèle économique, son cycle de vente et ses besoins en structuration.
3. Adapt this distribution to the maturity of the company
The stage of development directly influences the organizational structure:
- Launch / creation phase: priority to commercial functions. Support is often outsourced.
- Growth phase: ramping up marketing, first hires in HR/Finance.
- Scale-up phase: structuring processes, strengthening support functions, specializing teams.
The role of the external CFO is to support this transition with a progressive HR structuring plan, compatible with cash flow and strategic priorities.
Adjust ratios according to the industry sector
The weight of functions also varies according to the economic model:
- A consulting agency mobilizes 60% of its workforce in delivery, with few in Tech.
- A B2B SaaS platform requires a strong investment in Product/Tech from the outset.
- A training firm can sustainably outsource accounting, legal, or IT services to focus on core activities (pedagogy, client relations).
A good practice: regularly analyze the most time and energy-consuming tasks, and decide between recruitment, outsourcing, or automation.
5. Outsourcing support functions: a strategic lever
Outsourcing accounting, payroll, legal, financial management (part-time CFO), means:
- Reduce fixed costs
- Gaining agility
- Accessing senior expertise without hiring
This strategy is particularly effective during the launch or acceleration phase, where the priority remains commercial development.
Un DAF externalisé joue un rôle de chef d’orchestre, en veillant à l’équilibre entre développement, structuration et rentabilité.
Conclusion
The distribution of staff is a fully-fledged HR and financial management tool. It should be subject to regular monitoring, function-based analysis, and confrontation with the company's objectives.
