MSP vs Internal IT for Engineering Firms: Which Model Fits Your Texas Business?

Updated September 01, 2026

TL:DR For most Texas engineering firms between 80 and 150 employees, Co-Managed IT delivers better coverage and lower total cost than a second internal hire or a full MSP swap, but only when the math is built correctly. This article covers the true fully loaded cost of an internal IT hire, flat-fee MSP economics, and the five-question decision framework for identifying which model fits your firm. If you’re evaluating Texas MSP options, start here.

At an 80-to-150-employee Texas engineering firm, managed IT for engineering companies comes in three distinct forms: a second internal IT hire, a full managed services provider (MSP) that takes over all IT functions, and Co-Managed IT, where an MSP works alongside your existing IT person. Each model carries a different cost structure, a different coverage model, and a different level of political complexity. For most firms in this range, the MSP vs internal IT question is not whether to get more IT coverage. It is which model covers more for less without creating a personnel problem in the process.

What Each IT Model Actually Covers

The three models differ primarily in who owns coverage hours and who absorbs the risk when specialized knowledge is needed. An internal hire gives you one person with one schedule. A full MSP replaces that person with a team. Co-Managed IT adds a team around the person you already have.

What an Internal IT Hire Covers

A single IT Manager or Systems Administrator at an 80-to-150-employee engineering firm typically handles helpdesk tickets, hardware setup, network maintenance, basic security configuration, and new-hire onboarding. That scope fills a standard 40-to-50-hour week without leaving much margin.

The coverage limit is structural. A single hire working standard hours covers approximately 2,080 hours per year, roughly 24% of the 8,760 hours in a year. The remaining 76% (about 6,680 hours of nights, weekends, holidays, and sick days) passes without any dedicated IT coverage. That’s when servers fail and security events go undetected.

When that IT person is sick, on vacation, or gives notice, coverage drops to zero. Engineering firms with CAD/BIM workloads, multi-site physical networking, and high-value project data can’t absorb that gap without a plan.

What a Full MSP Covers

A full managed IT engagement delivers 24/7 monitoring, unlimited helpdesk, security management, backup oversight, and on-site visits when needed, all under one flat monthly fee. Cloud Cover IT’s analysis notes that one hire can’t realistically cover nights, weekends, vacations, and specialized security simultaneously. That’s the structural gap a full MSP closes.

The political reality of a full MSP: it typically means the existing IT person is repositioned or let go. For an Operations Leader who has managed that person and built the working relationship, that transition carries real internal risk. The IT person’s institutional knowledge (which servers have workarounds, which vendor relationships they own, which legacy systems they understand) doesn’t transfer on day one.

What Co-Managed IT Covers

Co-Managed IT is built on a clear division of responsibility. The MSP team handles 24/7 monitoring, tier-1 helpdesk tickets, security management, and after-hours response. The internal IT person keeps strategic ownership: infrastructure planning, vendor relationships, and the institutional knowledge they’ve spent years building.

As TechProComp’s co-managed service page describes the model: “Specialized support augments your internal IT team, filling skill gaps and handling overflow without replacing existing staff. Think of it as reinforcements for your current team, providing enterprise-level expertise and tools at a fraction of full-time hiring costs.” (TechProComp co-managed page) The IT person stays on the field for every strategic play. The MSP covers the 2 AM emergencies, the routine monitoring, and the security management.

With the majority of our team working remote, he is extremely flexible and understands the importance of keeping our team working. – Keith Kelley, Facilities Manager Salient Systems

The True Total Cost of Each Model

Most cost comparisons between an internal hire and an MSP only compare base salary to monthly fee. That comparison is wrong. The correct comparison includes employer-side benefits, tooling, training, recruiting costs, and what each model leaves uncovered. When you add all of those numbers together, the picture changes.

Fully Loaded Cost of an Internal IT Hire

The starting point is base salary. For a Systems Administrator-to-IT-Manager role at an 80-to-150-employee Texas firm, ZipRecruiter’s 2026 Texas data puts the Systems Administrator average at $82,849 per year, with the typical range between $65,200 and $96,900. IT Manager roles in Texas average $102,209 per year per ZipRecruiter, with the typical band running $88,500 to $108,500. For the 80-to-150-employee segment, a realistic base salary is $75,000 to $95,000 per year.

The BLS ECEC report (December 2025 data, released March 2026) confirms that benefits account for 29.9% of total employer compensation for private industry workers, meaning benefits add approximately 42% on top of wages. Applying that multiplier to the $75,000 to $95,000 base salary range puts salary-plus-benefits at $107,000 to $135,000 per year, before any tooling costs.

Annual tooling for a single IT person managing 80-to-150 employees adds another $10,000 to $20,000 per year. RMM tools run $2 to $15 per device per month, per Domotz’s 2026 pricing guide. Cybersecurity tools for a small business run $5,000 to $50,000 annually, per Execweb’s 2026 cost report. Add recruiting: direct-hire agency fees for IT positions run 15% to 30% of first-year salary, per KORE1’s 2026 IT staffing guide. Applying the midpoint (20% of an $85,000 salary) puts recruiting at roughly $17,000.

Add those numbers up: a single IT hire at an 80-to-150-employee Texas engineering firm carries a fully loaded Year 1 cost of $132,000 to $172,000. And that person still doesn’t provide 24/7 monitoring, security specialization, or coverage when they’re sick or on vacation.

Flat-Fee MSP Economics

Full managed IT in Texas runs $125 to $275 per user per month in 2026, according to TechProComp’s analysis of 50 Texas MSP providers. At $125 per user (the current market floor for truly full-managed IT), a 100-person firm pays $12,500 per month, or $150,000 per year. At $150 per user, the same firm pays $180,000 per year.

That annual fee replaces the internal IT person and covers 24/7 monitoring, unlimited helpdesk, security management, backup, and on-site visits. The coverage gap problem is structurally solved. But the existing IT person’s role needs to be addressed, which means managing that internal transition, including the institutional knowledge that walks out the door.

Co-Managed IT: The Hybrid TCO

Co-managed IT in Texas runs 30 to 50% lower than full managed IT, typically $75 to $140 per user per month based on the same TechProComp Texas MSP pricing analysis. For a 100-person firm at $100 per user, that’s $10,000 per month, or $120,000 per year for the MSP portion. Add the existing IT person at $108,000 per year fully loaded, and the combined co-managed TCO is approximately $228,000 per year.

Compare that to two internal IT hires at $108,000 fully loaded each: $216,000 per year, without 24/7 monitoring or security specialization. Co-Managed IT is more expensive than two hires on paper, but it adds continuous coverage, specialized security expertise, and no single-point-of-failure risk. And TechProComp’s co-managed page makes the value case directly: “Save 50% versus additional full-time hires while gaining deeper specialized knowledge.”

MSP vs. Internal IT: Side-by-Side Comparison

The table below maps the three models across the operational dimensions that matter most to an Operations Leader. Use it to identify which model fits your current situation before talking to any vendor.

Dimension	Internal IT Hire (Single)	Full MSP	Co-Managed IT
Annual Cost Range	$132K-$172K (Year 1, fully loaded)	$150K-$330K/yr (at $125-$275/user for 100 employees)	$108K-$228K/yr (existing IT person + $75-$140/user MSP fee)
Coverage Hours	~2,080 hrs/yr (24% of annual hours)	8,760 hrs/yr (24/7/365)	8,760 hrs/yr (24/7/365)
Includes 24/7 Monitoring	No	Yes	Yes
Includes Security Specialization	Limited (generalist only)	Yes	Yes
Transition Risk	Low (internal hire)	High (IT person displaced)	Low (IT person stays)
IT Person Impact	Requires new hire	Replaces existing IT person	IT person keeps strategic role
Contract Flexibility	N/A (employment)	Varies (often 12-month minimum)	Month-to-month available

For most 80-to-150-employee Texas engineering firms, this MSP vs internal IT breakdown points in one direction: Co-Managed IT covers more hours and more specialized functions than a second internal hire, at a comparable or lower risk level. Before you finalize that conclusion, the decision framework in the next section helps you confirm it applies to your specific situation.

The 5-Question Decision Framework

The five questions below map to the variables that determine which model fits your engineering firm. Answer them honestly before talking to any vendor. The answers will also tell you exactly what to say when your CEO asks why you’re recommending one model over another.

1. Is Your Current IT Person Staying?

If your IT person has given notice or is actively interviewing, Co-Managed IT may not stabilize the situation. The model works best when the internal IT person is staying but overwhelmed. They want relief, not a replacement. In that case, Co-Managed IT is the structurally correct answer.

If the IT person is genuinely looking to leave regardless of what you do, a full MSP transition may be the cleaner path. It avoids layering a co-managed arrangement on top of a succession problem. And per TechProComp’s co-managed positioning: the IT person keeps ownership of strategy and vendor relationships. The MSP adds a team around them, not above them.

2. How Many Locations Do You Have in Texas?

At two or more Texas locations, a single IT person physically can’t be on-site at all locations simultaneously. That’s not a staffing failure. It’s a coverage math problem. An MSP (full or co-managed) covers all Texas locations from a single contract.

TechProComp serves Austin, Houston, and San Antonio. As TechProComp’s engineering industry page states: “TechProComp has offices in Austin (HQ), Houston, and San Antonio. On-site technicians are dispatched locally to any office or project site. One provider, one flat fee, one team across all your Texas locations.” If your engineering firm has locations outside Texas, you’ll need a separate provider for those sites. That’s a constraint worth acknowledging before you sign anything.

3. Do You Have Compliance Requirements?

Engineering firms pursuing Department of Defense contracts need to take CMMC Level 2 seriously. CMMC Level 2 applies to contractors handling CUI, such as technical drawings, engineering specs, and other sensitive defense data, and requires full implementation of all 110 security controls in NIST SP 800-171 Rev 2. CMMC Phase 2 begins November 10, 2026, bringing mandatory third-party C3PAO assessment requirements for Level 2 contracts.

A single generalist IT person cannot implement and maintain 110 NIST SP 800-171 controls without specialized cybersecurity support. An MSP with a documented 12-layer security framework and SOC 2 certification (TechProComp: SOC 2 certified, verified March 2026) provides the structured, auditable security controls that third-party assessments require.

4. Can Your CEO Approve a Month-to-Month IT Contract?

The Operations Leader’s biggest objection to recommending an MSP is transition risk: what if it doesn’t work? The 0-0-0 Campaign (zero onboarding fees, month-to-month contracts, zero cancellation penalty) removes that risk structurally. You can present this to your CEO as: “If TechProComp doesn’t deliver, we leave with no penalty.”

The month-to-month structure is framed as confidence, not desperation. TechProComp publishes a 97% client retention rate (as published on techprocomp.com). They offer month-to-month because they earn the relationship every month. Standard MSP onboarding fees run $3,500 to $25,000 for a mid-size organization, per TechProComp’s Texas MSP pricing analysis (citing IronEdge Group data). The 0-0-0 Campaign eliminates that upfront financial risk entirely.

5. What Is Your IT Person’s Current Capacity?

Ask your IT person to estimate their actual workload: how many helpdesk tickets per week? How many hours per week on non-strategic work, password resets, printer issues, after-hours emergencies? If the answer is “most of it,” your IT person is functioning as a helpdesk, not a systems administrator.

Co-Managed IT frees them for strategic work by absorbing the helpdesk volume. Your IT person keeps infrastructure planning, vendor relationships, and the institutional knowledge they’ve built. The MSP takes the monitoring, the tier-1 tickets, and the 2 AM alerts. If you’re not sure whether your IT person is actually at capacity, signs you’ve outgrown IT walks through the specific indicators.

When Internal IT Is Still the Right Answer

Internal IT, either a single hire or a small team, is the right choice for a specific set of conditions. This article would be incomplete without naming them. The Co-Managed IT model is not the answer for every engineering firm, and honest evaluation requires acknowledging where internal hiring wins.

When the Firm Has Passed 150 Employees

At 150-plus employees with complex, multi-site infrastructure, the economics of a dedicated internal IT Director plus supporting staff start to compete directly with MSP fees. Internal control, institutional knowledge, and full-time presence become more valuable at that scale. TechProComp’s target customer is the 80-to-150-employee segment. At larger scale, a different model may be the right answer, and TechProComp acknowledges this boundary rather than overstating scope.

When the Engineering Work Requires Embedded IT

Some engineering disciplines require an IT person with deep domain knowledge embedded directly in the team. Defense contractors working with classified network segments, firms with specialized CAD/CAM environments requiring security clearance, or companies where IT is a direct competitive differentiator may need full-time institutional presence that a generalist MSP providing remote coverage can’t match.

In those cases, internal IT is the right structural fit for that firm. For a broader overview of how MSPs typically work in engineering contexts before you reach that conclusion, see what an MSP is for engineering firms.

Frequently Asked Questions

Is it cheaper to hire IT staff or use an MSP?

It depends on what you include in the cost comparison. A single IT Manager or Systems Administrator at a Texas engineering firm costs $132,000 to $172,000 per year when fully loaded, including salary, employer-side benefits (which add roughly 42% on top of wages per BLS data), tooling, training, and one-time recruiting fees. That figure still doesn’t cover 24/7 monitoring or security specialization. Full managed IT for a 100-person firm runs $150,000 to $330,000 per year in Texas (at $125 to $275 per user per month). Co-Managed IT, an MSP working alongside your existing IT person, often costs less than a second internal hire while covering more hours and specialized functions.

What is co-managed IT?

Co-Managed IT is a model where a managed IT services provider works alongside your existing IT person rather than replacing them. The provider handles 24/7 monitoring, tier-1 helpdesk tickets, security management, and after-hours response. Your IT person keeps strategic ownership of the environment, including infrastructure planning, vendor relationships, and the institutional knowledge they’ve built over time. The result is broader coverage without the cost and political complexity of a second full-time hire. It’s the model TechProComp is specifically built around, with clear responsibility documentation established during onboarding.

Can I have both an internal IT person and an MSP?

Yes, this is the Co-Managed IT model. The arrangement works when responsibilities are clearly divided from day one. The MSP takes monitoring, helpdesk volume, security updates, and after-hours response. The internal IT person takes architecture decisions, vendor relationships, and project oversight. A good co-managed engagement includes a written responsibility matrix before onboarding begins, so neither team is guessing whose job it is when something breaks. TechProComp’s co-managed model documents this division with a defined responsibility structure in the first seven days of onboarding.

When does an engineering firm need to hire IT staff?

An engineering firm typically needs dedicated internal IT staff when it exceeds 150 employees with complex, multi-site infrastructure, when it has defense contract requirements that mandate embedded security clearance, or when IT is a core competitive differentiator requiring full-time institutional presence. Below 150 employees with standard engineering firm IT needs, including helpdesk, security, network management, and CAD/BIM infrastructure, a Co-Managed IT model typically covers more ground at lower total cost than a second internal hire, without the recruiting timeline or ramp-up period.

How big does a company need to be before hiring IT staff?

Most Texas engineering firms can function effectively with one IT person and a Co-Managed IT partner up to approximately 150 employees across multiple locations. The math shifts when infrastructure complexity, compliance requirements, or site count outpace what a single IT person plus remote MSP support can handle. Below that threshold, the fully loaded cost of a second internal hire ($132,000 to $172,000 in Year 1) typically exceeds what Co-Managed IT costs for equivalent or better coverage, and the second hire still doesn’t provide 24/7 monitoring or specialized security expertise.

Key Terminology

Co-Managed IT: A model where a managed IT services provider works alongside a company’s existing IT person rather than replacing them. The MSP takes 24/7 monitoring, helpdesk volume, security management, and after-hours response while the internal IT person retains strategic ownership, including infrastructure planning, vendor relationships, and institutional knowledge. Co-Managed IT is TechProComp’s primary model for engineering firms with one IT person at or near capacity.

Managed Services Provider (MSP): A third-party IT firm that provides ongoing IT management and support under a contract, typically flat-fee, covering defined services for a fixed monthly cost. Unlike break-fix vendors who bill per incident, an MSP’s flat-fee model aligns the provider’s incentives with preventing problems rather than resolving them.

Total Cost of Ownership (TCO): The complete cost of maintaining an IT capability, including not just direct costs (salary or MSP fee) but indirect costs (employer-side benefits, tooling, training, recruiting fees, and the cost of coverage gaps). For an internal IT hire, the TCO typically runs 1.5 to 2 times the base salary when all indirect costs are counted.

Flat-Fee Pricing: An MSP pricing model where the client pays a fixed monthly amount covering all defined services with no per-ticket billing. This model contrasts with break-fix and time-and-materials arrangements where costs vary by incident, making IT budgeting unpredictable month to month.

SLA (Service Level Agreement): A contract term defining response and resolution time commitments for IT support. TechProComp’s published SLA guarantees a 3-hour response for critical issues and achieves a 97% Client Retention Rate (as published on techprocomp.com).

24/7/365 Monitoring: Continuous infrastructure monitoring that detects failures, security events, and performance degradation at any hour. A function that a single internal IT person working standard business hours cannot provide alone. Their 2,080 annual working hours cover only 24% of the year, leaving 6,680 hours without dedicated coverage.
