IT Team Size

0-1 dedicated IT

Key Priorities

  • +Cloud-first infrastructure (AWS, Azure, GCP)
  • +Core SaaS stack (Slack, Google Workspace, Notion)
  • +Basic endpoint security
  • +Password manager and MFA

Key Risk

Security is routinely underprioritised. Founders often treat IT as purely operational cost rather than a risk function.

Tip: Use managed services and cloud platforms to avoid the capital cost of on-premise infrastructure. Budget $100-$200 per employee per month as a starting point.

IT Team Size

Key Priorities

  • +First dedicated IT hire or MSP contract
  • +MDM for device management
  • +Email security (anti-phishing)
  • +Backup and disaster recovery

Key Risk

The first IT hire often inherits technical debt accumulated in startup phase. Security posture is usually below industry standard.

Tip: Consider a Managed Service Provider (MSP) at this stage rather than building a full internal team. Monthly retainer is typically $50-$150 per user.

Key Priorities

  • +IT governance and ITSM tooling
  • +Vendor consolidation
  • +Security operations (SOC or MDR service)
  • +Cloud cost management (FinOps)

Key Risk

Shadow IT proliferates as business units procure their own tools. SaaS sprawl is the biggest hidden cost at this stage.

Tip: Conduct a SaaS audit annually. Mid-market companies typically find 20-30% of SaaS licences are underused or redundant.

Enterprise

Key Priorities

  • +Digital transformation programmes
  • +Legacy modernisation
  • +Zero Trust security architecture
  • +AI/ML platform investment

Key Risk

Technical debt and legacy system maintenance can consume 30-50% of the IT budget, crowding out innovation spend.

Tip: A formal FinOps practice at this stage typically saves 15-25% of cloud spend within the first year. Cloud costs are usually the fastest-growing line item.

Large Enterprise

IT Team Size

Key Priorities

  • +AI scaling and agentic AI deployment
  • +M&A IT integration
  • +Compliance at scale (GDPR, SOX, industry-specific)
  • +Vendor negotiation and contract management

Key Risk

Complexity of the IT estate creates governance gaps. Shadow IT is endemic. Security incidents are more likely due to attack surface size.

Tip: Large enterprises have significant vendor negotiation leverage. Every 1% reduction in software licensing costs can save $1M+ annually at scale.

Frequently Asked Questions

How much should a 100-person company spend on IT?
A 100-person company (SMB to mid-market boundary) should budget approximately $100,000-$250,000 per year on IT, representing 4-7% of revenue depending on industry. At $2M in revenue, this is $80,000-$140,000. At $5M in revenue, this is $200,000-$350,000. The per-employee cost at this size is typically $1,000-$2,500 per year. Key costs are SaaS subscriptions, one or two IT staff or an MSP contract, cloud infrastructure, and security tools.
What is the average IT spend per employee?
The global average IT spend per employee is approximately $1,500-$3,500 per year across all company sizes and industries. Small businesses spend more per employee ($2,000-$5,000) because fixed costs are spread across fewer people. Large enterprises spend less per head ($800-$1,500) due to economies of scale in licensing and infrastructure. Financial services and technology companies spend more per employee ($3,000-$6,000+), while manufacturing and non-profits spend the least ($500-$1,500).
When should a company hire its first dedicated IT person?
Most companies benefit from a dedicated IT hire at 50-100 employees, when the complexity of managing devices, SaaS tools, and security across the team exceeds what non-specialists can handle. Between 50-100 employees, a Managed Service Provider (MSP) is often more cost-effective than a full-time hire. Above 100-150 employees, the cost of IT incidents and the complexity of onboarding and offboarding typically justifies a full-time IT role.
How does company size affect IT budget allocation between categories?
Smaller companies spend proportionally more on software and SaaS (because they use cloud-first tools) and proportionally less on personnel (because they lack the scale to justify large internal teams). Larger companies shift the balance toward personnel (large IT departments), legacy maintenance, and compliance. Security spending as a percentage of IT budget tends to increase with company size and regulatory exposure, from around 8-10% at startups to 15-18% at regulated enterprises.
