Traditional MSP, internal IT or a bank of hours: which Microsoft support model fits your organization?

Three models, three philosophies

When an organization of 30 to 500 employees looks for Microsoft support, it usually compares three options: the traditional MSP (monthly per-seat plan), hiring internally (one or two technicians of its own), or a bank of hours with access to a team of experts — the model behind our io4 360 offering.

Each has its zone of relevance. Here is the honest comparison, including the cases where io4 360 is NOT the right answer.

The traditional MSP: predictable, but generic

The classic MSP's per-seat plan offers real budget predictability and a responsive service desk for the day-to-day: workstations, printers, accounts, backups.

Its structural limit: deep expertise. A generalist MSP handles level 1-2 well, but specialized Microsoft work — Azure architecture, Purview governance, Copilot deployment, Defender incident response — often exceeds its bench. The other blind spot: the per-seat model incentivizes standardization, not optimization of your specific environment.

• Best for: organizations that want to delegate ALL of the day-to-day, with standard needs
• Blind spot: specialized projects (advanced security, AI, data governance)
• Question to ask: “how many expert-level Microsoft-certified people are on your team?”

Internal IT: the context, but a ceiling

An internal technician knows your company like no one else: real usage, history, internal politics. For organizations of 100+ employees, an internal core is often essential.

The limits are well known: one person cannot cover six domains of Microsoft expertise; vacations, departures and leaves create coverage gaps; and Québec's IT job market makes recruiting and retention costly and uncertain. The frequent outcome: an excellent internal generalist... spending their days on level-1 support instead of moving projects forward.

The io4 360 bank of hours: the expert team, without the hiring

The io4 360 model: an annual bank-of-hours contract giving access to the whole io4 team — Microsoft 365, Azure, security, Copilot and governance specialists — as needs arise. Weekly follow-up, quarterly governance, transparent consumption of hours.

Where the model shines: organizations that already have some internal autonomy (or an MSP for level 1) and need sharp expertise on demand, without hiring six specialists. Where it fits less: if you have no one internally and need someone to reset passwords every day — an MSP service desk does that better and cheaper.

• Best for: SMBs with an internal IT point person + varied project needs (security, migration, Copilot)
• Best for: public organizations — the multi-year bank of hours matches budget cycles and public tenders
• Less suited: high-volume level-1 daily support with no internal resource at all
• The models combine: several of our clients keep their MSP for the desk and use io4 360 for Microsoft expertise

The decision grid

• Under 30 seats, simple needs → traditional MSP alone
• 30-200 seats with an internal point person → io4 360 (+ level-1 MSP if volume warrants)
• 200+ seats → internal IT core + io4 360 for specialized expertise
• Public sector → multi-year bank of hours compatible with SEAO tenders
• In every case, demand transparency: detailed hour reports, regular governance, contract reversibility

Let's talk about your actual situation

The right model depends on your current team, your 18-month project roadmap and your risk tolerance. We will tell you frankly if io4 360 is not the right answer for you — it happens, and we'd rather say it over the first coffee than at the first renewal.
