Treat "free" as a procurement claim to test, not a conclusion. GLPI and other open-source ITSM tools remove the licence line, which is real and sometimes decisive. But a CFO does not budget licences; a CFO budgets total cost, and total cost for open source moves from the software vendor to your own infrastructure and headcount. The right comparison is not free versus paid. It is your fully loaded cost to run GLPI versus a commercial platform's subscription, both over three years. The wider mid-market picture sits in the 2026 mid-market ITSM platform cost comparison.
Is GLPI really free?
The software is, the operation is not. GLPI is open source and downloadable at no charge, and for a small team running a modest service desk that can genuinely be the lowest-cost path. What the download does not include is the hosting it runs on, the administrator time to configure and maintain it, the security patching it needs, the integrations to your identity and asset systems, and the paid support or plugins many organisations end up buying. None of these are hidden in any sinister sense; they are simply on your side of the ledger rather than the vendor's, which is exactly why they get left off the comparison.
What is the real total cost of open-source ITSM?
It is mostly people and hosting. The table frames the cost categories that replace the licence fee. Figures vary widely by estate size, internal labour rates and feature needs, so the discipline is to populate each line with your own fully loaded numbers rather than accept a generic estimate.
| Cost category | What it covers | Why it is easy to miss |
|---|---|---|
| Hosting and infrastructure | Servers, database, backups, scaling | Treated as existing overhead rather than a platform cost |
| Administration and maintenance | Configuration, upgrades, day-to-day admin | Buried in an existing salary, so it never reaches the business case |
| Security and patching | Keeping the platform and its dependencies current | Invisible until an audit or an incident makes it visible |
| Integrations | SSO, directory, monitoring, asset feeds | Built once, maintained forever, rarely costed |
| Support and plugins | Paid support contract, premium plugins | Bought later, once the free path hits a limit |
When does open-source ITSM stop being cheaper?
At the point where the internal effort to run, secure and integrate it, plus any paid support, exceeds the subscription of a comparable commercial tool. For a small, stable estate with spare administrative capacity, GLPI can stay cheaper indefinitely. As the estate grows, as compliance requirements harden, and as the feature gap with commercial platforms widens, the staff cost climbs and the gap closes. The crossover is specific to your rates and your needs, which is why a generic "open source is cheaper" or "open source costs more in the end" both fail as procurement advice. The number decides, not the slogan.
There is also a leverage point worth naming. A credible, costed open-source option is a useful benchmark in any commercial negotiation, because it sets a floor the incumbent has to beat on value rather than assume. Used honestly, the GLPI TCO model is as much a negotiating instrument as it is a buying decision. A related free-tier trap, where the entry price is zero but the real cost lands elsewhere, is examined in where the hidden costs land with Spiceworks free ITSM.
We build the three-year, fully loaded comparison as part of a contract negotiation engagement, so the open-source option is judged on total cost, not headline price. Fixed fee or gainshare.
How should a CFO frame the decision?
As a total-cost comparison over a realistic horizon, with the same rigour on both sides. Put the commercial subscription next to the fully loaded open-source run cost, including the staff time you would otherwise deploy elsewhere, and include the risk cost of carrying support in-house. Across ITSM engagements the firm has negotiated more than $420M in contract value across 10 platforms and averages a 30% reduction, and a recurring lesson is that the cheapest sticker price is rarely the lowest total cost. Open source can win that comparison or lose it; the value is in running it properly.
What to do next
Build the three-year model with your own loaded rates, populate every line in the table above, and compare it honestly against the commercial alternative you would otherwise buy. Use the result both ways: to make the buying decision and to set a floor in any commercial negotiation. When you want the model built and the comparison stress-tested, the engagement runs through our contract negotiation service on fixed fee or gainshare, and the board-level framing is in our CIO and CFO guide to ITSM cost.
Frequently asked questions
- Is GLPI really free?
- The software is free to download, but running it is not. You pay for hosting, administration, patching, integrations and often support or plugins. The licence is free; the operation is a recurring cost that belongs on the TCO.
- What is the real total cost of open-source ITSM?
- Mostly people and hosting: infrastructure, internal admin and maintenance, security patching, integration upkeep, and any paid support. Populate each line with your own loaded rates; figures vary widely by estate.
- When does open-source ITSM stop being cheaper?
- When internal effort plus paid support exceeds a comparable commercial subscription. Model both over three years with fully loaded staff cost before deciding, and confirm figures against your own rates.
