The verdict in three sentences
A food testing laboratory tracking 12,000 samples a year in spreadsheets is exposed to findings at its INAB assessment: incomplete traceability, uncontrolled method versions, reports retyped by hand. A custom LIMS aligned with ISO/IEC 17025 costs in the range of 60,000 to 120,000 EUR in Dublin in 2026, against an off-the-shelf LIMS at 30,000 EUR of licence plus 20% annual maintenance, almost always followed by heavy configuration. Custom makes sense when your methods, clients and instruments fall outside standard cases, and when you want to cut turnaround by one day.
What ISO 17025 and INAB expect from the system
ISO 17025 does not require a LIMS, but it demands data control that spreadsheets handle poorly. INAB assessors focus first on sample traceability, result integrity and calculation validation, and food labs serving FSAI official controls face extra scrutiny.
| ISO 17025 requirement | What the LIMS must do | Risk with spreadsheets |
|---|---|---|
| Sample traceability (7.4) | Barcode from receipt to disposal, cold chain | Handwritten labels, unlinked temperatures |
| Data control (7.11) | Role-based access, audit trail, versioning | Cells edited without a trace |
| Calculation validation | Locked formulas validated once | Copied and broken formulas |
| Equipment and calibration (6.4) | Blocks out-of-calibration instruments | Results produced on an expired instrument |
| Test reports (7.8) | Automatic generation, sign-off, accreditation statement | Retyped in Word, transcription errors |
| Complaints and nonconformities | Records linked to samples and actions | Tracked by email |
Off-the-shelf or custom LIMS: the five-year view
| Five-year cost line | Off-the-shelf LIMS | Custom LIMS |
|---|---|---|
| Initial licence | 30,000 EUR | 0 EUR |
| Vendor maintenance (20% a year) | 30,000 EUR | 0 EUR |
| Configuration, methods, report templates | 25,000 to 50,000 EUR | Included in development |
| Development | 0 EUR | 60,000 to 120,000 EUR |
| Instrument and client portal integration | 15,000 to 30,000 EUR | Included |
| Maintenance and hosting | Partly included | 30,000 to 45,000 EUR |
| Five-year total | 100,000 to 140,000 EUR | 90,000 to 165,000 EUR |
The totals are close. The difference is fit: an off-the-shelf LIMS imposes its data model, while custom software mirrors your sampling plans, your food industry clients and their product specifications. Kolonell builds applications of this level from Dakar for European labs; the exact scope and price are set in a quote.
Modules to prioritize
The first release should cover barcode sample receipt, result entry with specification limits, equipment management and report generation. The client portal (request submission, result access, out-of-spec alerts) comes second. Instrument integration (chromatographs, spectrometers, microbiology analyzers) runs through file exports or direct interfaces depending on the model.
Also plan computerized system validation: a test file proving the LIMS calculates and records correctly. INAB will ask for it at the first assessment after go-live.
Questions to settle before kickoff
Three decisions shape the budget more than anything else. The first is how many instruments need a direct interface rather than a file import: each one adds cost and validation work. The second is whether clients get a portal at launch or in a second release; producers value it, but it can wait three months. The third is who owns validation: the lab writes the user requirements and approves test results, the developer supplies scripts and evidence. Settling these in the first two weeks of discovery prevents the scope creep that pushes many LIMS projects past their assessment date. Ask also for a clear exit clause with a full export of samples, results and audit trails in an open format.
Mini case study
Aoife, quality manager of a food testing lab in Dublin (22 analysts), processes 12,000 samples a year for meat, dairy and ready-meal producers. Average turnaround is 4 days, with 1 day lost to retyping, checking and formatting reports.

- Report drafting and checking: 15 minutes today, 3 minutes with automatic generation
- Gain: 12 × 12,000 = 144,000 minutes, or 2,400 hours a year
- Loaded analyst cost: 38 EUR per hour
- Annual saving: 2,400 × 38 = 91,200 EUR
On a 100,000 EUR project, payback comes in about 13 months. Turnaround drops from 4 to 3 days, a decisive argument for producers who release batches based on lab results.
FAQ
Will INAB accept a custom LIMS?
Yes, INAB does not mandate any vendor. It checks data control and system validation, which a documented test file of 80 to 150 scenarios demonstrates.
How long does the project take?
Plan 6 to 9 months, including 6 weeks of method scoping. Go live at least 4 months before your assessment.
Can we import our historical spreadsheets?
Yes, the last 3 to 5 years of results can be imported to keep trends per client and product, after about 3 weeks of cleanup.
Can every instrument be connected?
Most export usable CSV or XML files. Each direct interface costs roughly 2,000 to 6,000 EUR depending on the protocol.
Where is the data hosted?
In the EU, with a certified host, daily backups and result retention for at least the period your clients require, often 5 years, in line with GDPR.
