How to Size an IT Team for a Subsidiary with Fewer Than 100 Employees

The 3 essential minimum positions for a subsidiary with fewer than 100 employees

Before we talk about headcount, let’s be clear: a subsidiary with 50 to 100 employees in Mexico is not a miniature version of the headquarters . It is a separate entity, with its own operational departments, its own labor market, and its own risks. Sizing the IT team as if it were a scaled-down replica is the number one mistake we see time and time again.

That said, there are three requirements that are non-negotiable:

• IT Site Lead — sole person responsible for IT operations in Mexico, liaison with headquarters , and manager of local vendors. Minimum of 1 internal FTE for organizations with 50 or more employees. This role ensures that IT decisions do not get stuck between two time zones.
• User Support (N1/N2) — first point of contact, ideally outsourced to a MSP that ensures continuity, a physical presence, and trilingual support (ES · EN · FR). In-house staffing for this role is costly and difficult to maintain during vacations, sick leave, or peak periods.
• Coordination with headquarters architecture — a senior-level role that facilitates technical decisions with the European CIO. This could be a 0.3–0.5 FTE position shared with headquarters, an external specialist consultant, or a role handled by the IT Site Lead if they have the appropriate technical background.

When to Insource vs. Outsource — Cost-Control Matrix

The decision isn't philosophical; it's practical. Use this framework as a starting point:

Function TypeFrequency / CriticalityRecommendationUser Support (N1)High frequency, low complexityOutsource with SLA Systems SLA frequency, medium complexityOutsource or share resources with headquarters IT Coordination / Vendor ManagementDaily, high business impactIn-house — minimum 0.5 dedicated FTE Operational cybersecurityContinuous, high criticalityLocal MSSP with monitoring from headquarters Projects and implementationsOne-timeExternal consulting on a project basis.
‍

The rule of thumb: Handle internally what pertains to day-to-day business operations and what requires cultural and relational context. Outsource what can be executed based on clear, measurable technical specifications.

A realistic budget for Mexico City

The salary markets in Mexico City and Monterrey have changed significantly over the past three years. The following are approximate gross monthly figures in Mexican pesos (MXN) for candidates with 3 to 6 years of experience, as of May 2026:

• IT Site Lead (management level): MXN 55,000–90,000 gross per month.
• N1/N2 Support (internal profile): MXN 18,000–32,000 gross per month, or a per-user rate under the MSP model MSP typically MXN 350–700 per user per mes SLA).
• System Administrator / Network Administrator: MXN 35,000–55,000 gross per month.
• Cybersecurity Specialist: MXN 50,000–85,000 gross per month, or MSSP fee MSSP protected endpoint.
• Project Consultant: MXN 1,800–3,500 per day on a professional fee basis.
  ‍

For a subsidiary with 50 employees operating under a hybrid model (1 in-house staff member + outsourced services), a reasonable annual IT operating budget ranges from 1.2 to 2.0 million MXN, excluding software licenses and cloud infrastructure, which are typically managed by headquarters.

The most common mistakes made when directly copying the European model

We've all seen them. The most common ones are:

• Replicating the European IT organizational chart on a larger scale —ignoring the fact that the labor market, regulations, and vendors are different. What works in Lyon with five specialized roles doesn’t work in Mexico City with 1.5 local FTEs.
• Underestimating the importance of extended-hours, trilingual user support —Mexican employees don't want to wait 8 hours for headquarters to headquarters . Without local support in their language, IT loses credibility.
• Bring operational cybersecurity in-house when a MSSP costs less and delivers better SLA, with 24/7 monitoring and experience handling real-world incidents that no single professional can match.
• If you entrust coordination with headquarters someone in a full-time operational role, that person will end up neglecting one of the two functions—usually strategic coordination.
• Failure to document responsibilities — without a clear RACI matrix, everything falls on the IT Site Lead, who ends up doing the work of three roles and burns out in less than 18 months.

This template is not an absolute truth. It is a starting point that has been validated across dozens of subsidiaries. Every organization has its own unique characteristics— ERP , industry regulations, level of digital maturity—that may warrant adjustments.
