CMMS: Custom vs Off-the-Shelf for a Food Plant in Montreal (2026)

The verdict in three sentences

A food plant with 250 machines suffering 8% unplanned downtime loses several weeks of production every year. An off-the-shelf CMMS is enough when processes are standard, but it handles poorly the HACCP traceability, post-intervention hygiene checks and automatic readings from PLCs. A custom CMMS, at 60,000 to 160,000 CAD as a 2026 market estimate, makes sense when the goal is to cut downtime by 30% and pass audits without re-keying.

The real cost of unplanned downtime

Before comparing software, put a number on the problem. On a packaging line, an hour of downtime costs lost output, idle labour, perishable product to discard and sometimes retailer penalties.

With 6,000 operating hours a year, 8% downtime equals 480 hours. Moving to 5.6% frees about 144 production hours per line.

Off-the-shelf or custom CMMS: the comparison

SaaS platforms are fast to deploy and cheap at first. Their limits show in food processing: hygiene forms after interventions, quality sign-off before restart, links to production lots and a bilingual French and English interface required for Quebec teams.

The balance often tips beyond 25 users and a 4 to 5 year horizon, or when the plant is preparing a demanding SQF or BRCGS certification.

Must-have features in food processing

A CMMS for this sector must manage the preventive maintenance plan per machine (run hours, cycles, calendar), work requests from a smartphone with photos, spare parts inventory with alert thresholds, and the return-to-service sign-off by quality. That last point is often forgotten: after work on a food contact line, the line must not restart without a logged sanitation check. A custom CMMS can also read PLC counters to trigger maintenance based on actual usage rather than the calendar.

On compliance, the Safe Food for Canadians Regulations (SFCR) require clear preventive control records, and Quebec Law 25 applies to personal data about technicians. Quebec's Charter of the French Language also makes a French interface a requirement for shop floor software.

Mini case study

Illustrative example: Marc, maintenance manager at a 250-machine dairy plant in Montreal, records 480 hours of unplanned downtime a year on his main line. An hour of downtime costs him 4,000 CAD. With a custom CMMS priced at 120,000 CAD in this scenario, he targets 30% less downtime, which means 144 hours recovered and 576,000 CAD of protected output a year. Even at half that target, the annual gain reaches 288,000 CAD, for software maintenance of 20,000 CAD a year. Payback comes in under 6 months.

FAQ

How long does a custom CMMS take to deploy?

Allow 4 to 7 months, including 4 to 6 weeks of asset inventory and preventive plan setup. A first version with work requests and preventive scheduling can run from month three.

Do technicians need smartphones?

An offline-capable mobile app is recommended, on devices costing 300 to 600 CAD. Data syncs as soon as plant Wi-Fi is available.

Can we import our Excel history?

Yes, work order history and asset lists usually import in 1 to 2 weeks. Plan for cleanup, as existing files often contain 20 to 30% duplicates.

Does a CMMS help with SQF or BRCGS audits?

It provides the evidence auditors ask for: preventive plan followed, logged work orders, return to service approved by quality. Document preparation drops from several days to a few hours.

What annual budget after launch?

A market estimate of 15 to 20% of the build cost, so 18,000 to 24,000 CAD for a 120,000 CAD project, including hosting and minor improvements.
