In-House IT vs. Managed IT for Law Firms: The Real Cost Comparison

You need reliable IT. That much is obvious. The question is whether you hire someone to sit in your office or pay an outside firm to handle it. Both options work — but the economics, coverage, and risk profiles are fundamentally different.

This is the comparison I wish someone had handed me before I started advising law firms on this decision. No vendor pitch. Just the numbers and the trade-offs.

The Side-by-Side Comparison

Before diving into the math, here’s how the two models stack up across the dimensions that actually matter to a managing partner:

Factor	In-House IT Hire	Managed IT Services
Monthly Cost (25-person firm)	$9,200–$13,300/mo	$3,750–$6,250/mo
Coverage Hours	8–5, Monday–Friday	24/7/365
Expertise Depth	One generalist (maybe two)	Team of specialists across security, networking, cloud, compliance
Scalability	Hire another person ($$$)	Adjust user count on the contract
Compliance Knowledge	Depends on the individual	Built into the service model (HIPAA, SOC 2, state bar requirements)
Vacation/Sick Coverage	Zero coverage or expensive backup	No gaps — team-based model
Response Time	Fast when they’re at their desk	SLA-backed, typically 15–30 min for critical issues
Institutional Knowledge	High (one person knows everything — which is also a risk)	Documented, shared across the team

The Real Cost of an In-House IT Person

Let’s break this down honestly. Firms that tell me “we pay our IT guy $85K” are only counting the salary line. Here’s what it actually costs to have a competent IT person on staff:

Compensation:

Salary: $85,000–$120,000 (for someone competent enough to handle a law firm’s compliance and security needs — not a junior help desk tech)
Benefits (health, dental, 401k match, PTO): add 25–35% = $21,000–$42,000

Tools and Licenses:

Security stack (endpoint protection, email filtering, SIEM): $8,000–$12,000/yr
RMM and monitoring tools: $3,000–$5,000/yr
Backup and disaster recovery platform: $4,000–$8,000/yr

Professional Development:

Training and certifications (CompTIA, Microsoft, security certs): $3,000–$5,000/yr
Conference attendance: $2,000–$4,000/yr
Time spent on training (unbillable but real): $5,000–$6,000/yr in opportunity cost

Total Annual Cost: $131,000–$202,000

And that assumes nothing goes sideways. A ransomware incident, a compliance audit finding, or a major migration project will blow past those numbers in a week.

The hidden cost nobody talks about: when your one IT person quits, you’re starting from zero. The recruitment cycle alone costs $15,000–$30,000 (recruiter fees, lost productivity, onboarding), and you’re exposed for 60–90 days while you find a replacement.

The Real Cost of Managed IT Services

IT consulting for law firms typically runs on a per-user, per-month model. Here’s what that looks like for a 25-person firm:

Fully Managed IT (the most common model):

Per-user cost: $150–$250/month
25 users: $3,750–$6,250/month
Annual cost: $45,000–$75,000

That typically includes:

24/7 help desk and support
Proactive monitoring and maintenance
Patch management and updates
Basic cybersecurity (endpoint protection, email filtering, MFA enforcement)
Backup management
Vendor coordination (your copier company, your phone system, your ISP)
Quarterly business reviews

What’s usually extra:

Major projects (office moves, full infrastructure overhauls): billed separately
Advanced cybersecurity (SOC monitoring, penetration testing): $1,000–$3,000/mo add-on
Compliance-specific work (HIPAA assessments, written security policies): project-based

Even with add-ons, most firms land at $60,000–$90,000/year for comprehensive IT support for law firms — still 40–55% less than the in-house option.

When In-House Makes Sense

In-house IT isn’t wrong. It’s wrong for most small and mid-sized law firms. Here’s when it actually makes sense:

You have 100+ employees. At that scale, the per-user economics of managed services start to flatten, and the complexity justifies dedicated staff. You’ll likely want an IT director plus an MSP for overflow — but the in-house leadership role pays for itself.

You have custom application development needs. If your firm has built proprietary case management tools, client portals, or integrations that need ongoing development, that’s a full-time engineering role — not an MSP engagement.

You have a dedicated IT budget with executive buy-in. If the firm treats IT as a strategic function (not just “keep the internet working”), an in-house team with real budget authority can drive transformation. This is rare in firms under 75 attorneys.

You’re in a niche with extreme regulatory requirements. Some government contract work or national security-adjacent practices require cleared personnel with direct control over infrastructure. Managed services can’t always meet these requirements.

When Managed IT Makes Sense

For most law firms between 10 and 100 employees, managed IT services for law firms are the better fit — and we reviewed the best managed IT providers serving law firms if you want to see how they compare. Here’s why:

You need 24/7 coverage but can’t justify three shifts. A single IT hire gives you 40 hours of coverage per week. That’s 23.8% of the hours in a week. Attorneys work nights and weekends. Opposing counsel sends discovery at 11 PM. Deadlines don’t respect business hours.

You need compliance expertise without hiring a compliance officer. State bar associations, cyber insurance carriers, and clients (especially corporate clients) are increasingly demanding proof of security controls. A good MSP bakes this into their service — it’s not an afterthought.

You have multiple offices or remote workers. Managing distributed infrastructure with a single IT person is a recipe for inconsistency and gaps. MSPs are built for this.

You want predictable costs. A flat monthly fee means you can budget IT like rent — no surprise invoices when the server crashes or a laptop gets stolen.

You’d rather your IT dollars buy proactive work, not just firefighting. In-house IT people spend 60–70% of their time on reactive support. MSPs automate the routine work and focus human effort on improvements and prevention.

The Hybrid Model: Best of Both Worlds

The firms I see getting the best results often use a hybrid approach:

One in-house IT coordinator (not a full sysadmin — more of a tech-savvy operations person) who handles day-to-day requests, manages vendor relationships, and serves as the internal point of contact. Salary: $55,000–$75,000.
An MSP for the heavy lifting — security, compliance, monitoring, after-hours support, project work, and strategic planning.

This gives you the institutional knowledge and immediate responsiveness of an internal person, with the depth, coverage, and scalability of a managed services team. Total cost typically runs $100,000–$140,000/year, which is competitive with a solo in-house hire but delivers dramatically more capability.

How to Evaluate: Total Cost of Ownership

When you’re comparing options, don’t just look at the monthly invoice or the salary number. Calculate the total cost of ownership:

For in-house, include:

Fully loaded compensation (salary + benefits + payroll taxes)
All tools, licenses, and subscriptions they’ll need
Training and professional development
Recruitment costs amortized over average tenure (3–4 years for IT staff)
Coverage gaps (vacation, sick days, turnover)
Opportunity cost of a single point of failure

For managed services, include:

Monthly per-user fee times 12
Average annual project spend (ask the MSP for examples from similar clients)
Any add-on services you’ll actually need (security, compliance, etc.)
Cost of the transition and onboarding period

For hybrid, include:

Internal hire (reduced role/salary) + MSP fees + coordination overhead

Then ask yourself: what’s the cost of getting it wrong? For a law firm, a data breach doesn’t just mean downtime. It means bar complaints, malpractice exposure, client attrition, and reputational damage that takes years to rebuild. The cheapest option is rarely the least expensive in the long run.

The Bottom Line

For a 25-person law firm, managed IT services typically cost 40–55% less than a full-time hire while delivering broader coverage, deeper expertise, and better compliance posture. The math gets even more favorable when you factor in risk — an MSP’s entire business model depends on keeping you secure and operational, while a solo IT hire is one bad day away from leaving you exposed.

The right answer depends on your firm’s size, complexity, and growth trajectory. But if you’re a managing partner at a 10–75 person firm still debating this, the numbers almost always favor managed services — either standalone or in a hybrid model.

The best next step is straightforward: get a real proposal from a qualified MSP, lay it next to your current IT spend (all of it, not just the obvious line items), and compare.
