Most labs run their LIMS for ten to fifteen years before they replace it. That makes the initial choice expensive in a way that is not visible on the first invoice. The wrong fit shows up year five, year eight, when the workflow has grown and the vendor has moved on. This article is about how to evaluate that ten-year view, not the demo.
The two paths
You are choosing between two procurement models.
Commercial LIMS is a license you pay for, usually per user per year, often with a five-figure implementation project on top. The vendor owns the code and decides what is in the roadmap. You get polish, sales support, and a clear point of accountability.
Open-source LIMS is software you can download. You pay for the people who set it up, customise it, train your team, and keep it running. You own the configuration and the data. The roadmap is public.
Neither is universally better. They optimise for different things.
Cost over ten years
The headline numbers tell you very little. The total cost lives in four places.
- License or subscription. Proprietary LIMS for a 25-user lab typically lands at EUR 2,500 to EUR 3,000 per month, so EUR 300k to EUR 360k across ten years. Open source is zero.
- Implementation. A proprietary implementation project runs EUR 24k to EUR 60k. Open source has setup costs too, but they tend to be a single workshop and the work that follows it.
- Customisation and integrations. Both stacks need this. The difference is who can do it. With open source, anyone can. With proprietary, only the vendor can, and they bill for it.
- Operations. Hosting, monitoring, backups, security updates. Either you do it, or you pay someone. SENAITE Care handles this end of the stack from EUR 300 per month.
A typical ten-year total: EUR 300k+ for commercial, EUR 90k to EUR 150k for SENAITE with our Professional Care + hosting tier. The savings compound when you have more users, more sites, or more years.
Customisation
The honest question is not “can it be customised” but “can it be customised by someone other than the vendor.”
With SENAITE, the answer is yes. Custom calculations, new analysis services, specific report layouts, edge-case workflows, instrument protocols nobody else has asked for. Anyone fluent in Python and Plone can do it. We do it as our day job. Your in-house developer can do it. A contractor you trust can do it.
With proprietary LIMS, the answer is “yes, by us.” Quoted, billed, delivered when the vendor schedules it. For mainstream features this is fine. For specialised industrial workflows it is the single largest pain point we hear from labs that switch to us.
Vendor lock-in
A LIMS holds operational data that is hard to reproduce. Switching costs come from three places:
- Schema. Can you read the database and understand the data? With SENAITE, the schema is in the code. With proprietary, the schema is whatever the vendor exports for you.
- Workflows. The configured states, transitions, and rules. These are real intellectual work and not easily portable.
- Integrations. Every instrument cable, every customer-facing export, every script that feeds another system.
Open source lowers all three. You can read the schema. The workflow lives in files you can copy. Integration code is yours.
Compliance and audit
Both can satisfy ISO 17025, FDA 21 CFR Part 11, GxP, IVDR. Compliance is a property of your operational procedures plus the system’s audit trail and access control, not of the license model.
SENAITE has a complete audit trail, role-based access, electronic signatures, and a validated deployment path. For validated environments (GxP, IVDR, clinical diagnostics), we provide IQ/OQ documentation, a signed SLA, frozen versions, and source-code escrow on request through the SENAITE Care Enterprise tier or a custom contract.
One advantage of open source for compliance: auditors can see exactly what runs. The code is part of the documentation.
When commercial is the right answer
It exists. A few situations where we tell labs to take the proprietary path instead:
- You need exactly the workflow the vendor sells, with no changes. Some vertical-specific products (e.g. clinical immunoassay analysers) ship with their LIMS already shaped to the analytical workflow. If that fits, fit is cheaper than flexibility.
- You have no in-house technical capability and do not want to buy any. Open source needs a partner. If you do not have one and do not want one, commercial is simpler.
- The vendor’s customer base includes labs structurally identical to yours. Reuse beats invention.
When SENAITE is the right answer
The cases where SENAITE wins are also clear:
- Your workflow is yours. Industrial QC, environmental monitoring, mining, multi-site water utilities. Domains where every lab is a little bit different.
- Cost per user is going to matter. Above ~10 users the per- user licensing curve gets ugly.
- You want to read the code. Regulated industries, security- conscious IT teams, organisations that have been burned by a vendor before.
- You want to keep your data. Government agencies, public utilities, anyone with a data-sovereignty requirement.
How to evaluate
We recommend the same path to every lab considering us:
- Take a 3-day workshop. Real lab data, your samples, your workflow. By Friday you have a configured system you can take home as a VM. Details here.
- Talk to references. We connect labs that ask. People who have run SENAITE for five years know things the demo does not show.
- Cost the ten-year view, not the first year. License is only one of four lines. The other three matter more.
