Build or Buy? How to Decide If You Should Outsource IT or Keep It In-House

Written by Alex Davis | Jun 26, 2025

As your business grows, so does the complexity of your technology needs. At some point, every company faces the pivotal question: Should we build an internal IT team or outsource to a managed service provider (MSP)? 

There’s no one-size-fits-all answer, but there is a smart way to decide. In this guide, we’ll help you evaluate both options with a practical framework and show you the scenarios where outsourcing IT makes the most sense—and when an internal team might be justified. 

 

What Does “Build vs. Buy” Really Mean in IT? 

  • Build = Hiring in-house staff to manage your IT systems, support, security, and strategy. 
  • Buy = Partnering with an external provider to handle all or part of your IT needs (often through a Managed Service Provider or MSP). 

Both approaches have pros and cons, depending on your company’s size, goals, industry, and growth stage. 

 

Your Decision Framework: 5 Key Considerations

 

1. Budget and Cost Predictability

  • Build: High up-front investment in salaries, benefits, tools, and training. You may also need to hire multiple specialists (network, cloud, security). 
  • Buy: Predictable monthly cost with access to a full team of experts. No surprise costs for turnover or emergency support. 

Outsource if: You need cost control, flexibility, or can’t afford a full internal team. 

Keep in-house if: You have a larger IT budget and long-term hiring capacity. 

 

2. IT Complexity and Compliance Requirements

  • Build: May work for companies with simple, static environments and minimal compliance demands. 
  • Buy: MSPs bring industry-specific compliance expertise (HIPAA, FINRA, SOX, NIST) and are structured for 24/7 monitoring, patching, and audits. 

Outsource if: You operate in a regulated industry or manage sensitive client data. 

Keep in-house if: You already have a compliance-savvy IT leader with the bandwidth to manage risk. 

 

3. Scalability and Growth Plans

  • Build: Scaling requires recruiting, onboarding, and training additional staff—often slower and more costly. 
  • Buy: MSPs scale on demand. Whether you're adding headcount, locations, or cloud services, they can ramp up fast. 

Outsource if: You anticipate rapid growth or fluctuating IT needs. 

Keep in-house if: Your growth is predictable and you have a long-term plan to build IT capacity. 

 

4. Access to Expertise

  • Build: One or two internal hires can rarely cover everything—cybersecurity, cloud strategy, network management, help desk, and more. 
  • Buy: Outsourced IT gives you access to a wide bench of specialists, often with certifications and experience across multiple industries. 

Outsource if: You need broader expertise than you can afford to hire internally. 

Keep in-house if: You can afford a multi-role team or already have specialized staff. 

 

5. Business Agility and Innovation

  • Build: Internal teams can be close to operations but may get bogged down with tickets and lack time for strategic projects. 
  • Buy: An MSP provides structured processes, automation, and tools that support innovation and agility. 

Outsource if: You want to offload day-to-day IT so you can focus on strategic growth. 

Keep in-house if: Your IT team is already embedded in product development or mission-critical R&D. 

 

What About a Hybrid Model? 

You don’t have to choose one or the other. Many growing businesses use a co-managed IT approach, where internal staff handles on-site support or user-specific needs, and an MSP handles security, compliance, monitoring, and high-level strategy. 

This hybrid approach gives you the best of both worlds: local insight and enterprise-grade support. 

 

Real-World Scenarios: When to Build or Buy

Buy 

 

 

Final Thoughts: Build Smart, Buy Strategically 

Your IT function is too important to get wrong. Whether you build or buy, the goal is the same—reliable systems, protected data, happy users, and a platform that supports your growth. 

Outsourcing IT isn’t just a cost-saving measure. It’s often the fastest way to elevate your operations, gain strategic insight, and protect your business from risk.
