In-House IT vs MSP: Which Is Right for Your Stage of Growth?

Many 50 to 100-seat organisations reach a point where internal resources feel stretched, and technology becomes difficult to manage. Systems expand, support requests increase, and cyber risks rise. This article sets out a clear comparison between in-house IT and a managed IT service provider to help leaders decide which model best supports their current stage of growth.

Key points:

• In-house IT provides familiarity and control, but can be difficult to scale during rapid growth.
• An MSP offers broader capability, 24/7 coverage, and predictable costs.
• Growing organisations often benefit from a blended model that strengthens internal capacity.
• The right choice depends on operational needs, risk exposure, and expected change.

What growing organisations need from IT today

Growing organisations depend on steady systems, reliable support, and clear communication. Leaders want predictable costs, strong security controls, and a support model that keeps pace with change. They also need visibility into tickets, assets, licensing, system health, and future planning.

Internal teams often handle daily tasks well, but as the organisation grows, the range of skills required expands. Cybersecurity expectations increase, cloud services become more complex, and users expect faster support across extended hours.

Managed service providers work as an embedded technology team. They offer structured SLAs, documented processes, Essential Eight–aligned security, and access to a broader group of engineers.

In-house IT vs MSP: a clear comparison

When an in-house IT team works well

An internal team performs well in stable environments with consistent user needs. They understand daily workflows, internal processes, and local systems. This model works when the organisation can support ongoing training and invest in additional staffing as demands increase.

Scenario: a Brisbane legal practice with steady operations

A legal practice with around 50 staff may rely on an internal IT coordinator to manage document systems, printers, access requests, and court-related workflows. The internal resource knows the practice well and provides consistent onsite support.

As the practice grows, cybersecurity obligations, after-hours expectations, and cloud complexity increase. At this point, a single internal resource may struggle to cover everything, especially across monitoring, incident response, and specialised skills.

When an MSP is a better fit for growth

An MSP suits organisations that expect continued growth, increased security requirements, or broader operational needs. The model gives leaders predictable costs and access to a larger team with wider capabilities. This includes 24/7 support, Essential Eight–aligned security, documentation, and proactive monitoring.

Scenario: a healthcare provider expanding to multiple sites

A healthcare organisation opening new locations must maintain strong security controls, protect patient information, and support clinical teams across extended hours. An MSP provides monitoring, cloud management, centralised systems, and consistent support across all sites.

Scenario: a manufacturing business needing reliable operations across sites

Manufacturing environments depend on steady systems, network reliability, and clear communication. An MSP provides structured maintenance, monitoring, and engineering support to maintain uptime.

Blended models: the middle-ground option

Some organisations use a blended model. An internal coordinator or IT manager works with an MSP to cover user support, cybersecurity, cloud environments, and after-hours coverage. This removes single points of failure and strengthens the organisation during periods of change.

How to decide: a simple framework for leaders

Leaders can review the following areas when deciding which model fits best:

• Expected growth over the next 12 to 24 months
• Current response times and internal workload
• Cybersecurity expectations and regulatory needs
• The level of visibility required for tickets, assets, and system health
• Whether the organisation can support ongoing training and staffing

A clear view of these factors helps determine whether internal IT, an MSP, or a blended model provides the right level of stability and support.

Where managed IT services fit into your long-term plan

Managed IT services support long-term stability. They provide documented processes, structured reviews, Essential Eight–aligned security, predictable costs, and a team that maintains steady systems as the organisation grows. This approach helps leaders plan ahead and maintain clarity.

Frequently Asked In-House IT vs. MSP Questions

1. Is an MSP more cost-effective than hiring additional IT staff?

Costs depend on the organisation’s needs. Independent research shows that outsourced IT can reduce operational expense for growing organisations by replacing several internal roles with a single predictable fee. This can be more efficient where broad capability is required.

2. Can a business keep its internal IT team and still use an MSP?

Yes. Many organisations keep an internal IT coordinator or manager and use an MSP for broader coverage, cybersecurity, and after-hours support. This removes single points of failure and strengthens operational resilience.

3. What does an MSP typically cover day to day?

An MSP handles user support, monitoring, cloud services, system maintenance, security controls, and incident response. Research shows that organisations using structured managed services report reduced downtime and improved ticket response times.

4. How fast can an MSP respond compared to in-house IT?

An MSP uses structured SLAs to maintain consistent response times. Studies show that managed service models reduce average resolution times through dedicated teams and monitoring tools.

5. When should a growing organisation consider switching to an MSP?

A switch is often considered when response times slow, cyber expectations increase, or internal resources are stretched. This model provides broader capability and steady support as user numbers rise.
