The verdict in three sentences
For a food plant with 180 assets and 3 shifts, a well-configured off-the-shelf CMMS is enough as long as your food safety requirements stay standard and you have no sensors to connect. Once you need to link maintenance to batch traceability, sanitation plans and machine data, a custom CMMS at $50,000 to $100,000 pays back within 18 to 30 months. The real lever is not the tool but a 20 to 35% cut in unplanned downtime, which outweighs any licence fee.
What 6% unplanned downtime really costs
On a food packaging line in the UK or North America, one hour of downtime costs, as a 2026 order of magnitude, between $1,600 and $4,400: lost output, catch-up overtime, perishable raw materials written off and service-level penalties from retailers. With 6% unplanned downtime over 5,800 operating hours a year, that is close to 350 lost hours.
| Item | 2026 assumption | Estimated annual cost |
|---|---|---|
| Unplanned downtime hours | 6% of 5,800 h, i.e. 348 h | calculation base |
| Lost output | $1,300 per hour | $452,400 |
| Downgraded materials (shelf life, cold chain) | 15% of stoppages, $2,700 per incident | $28,000 |
| Catch-up overtime | 3 technicians x 120 h x $50 | $18,000 |
| Retailer service-level penalties | 1 to 3% of affected customer revenue | $11,000 to $33,000 |
| Rush-ordered spare parts | 35% average premium | $13,000 |
| Total | about $520,000 to $545,000 |
A 25% downtime reduction is therefore worth about $130,000 a year. That figure, not the licence price, should frame your budget.
Off-the-shelf vs custom CMMS: the 2026 comparison
Vendors such as Fiix, UpKeep, Limble, MaintainX or Carl Source offer solid products. Custom development makes sense when your workflows go beyond what configuration allows.
| Criterion | Off-the-shelf CMMS | Custom CMMS |
|---|---|---|
| Licences | $55 to $130 per user per month | $0, code delivered to the plant |
| Configuration or development | $11,000 to $27,000 | $50,000 to $100,000 |
| Time to go live | 2 to 4 months | 4 to 7 months |
| Food safety traceability (batches, sanitation, foreign bodies) | partial, optional modules | native, linked to work orders |
| Sensors (vibration, temperature, meters) | standard connectors, often paid | custom MQTT or OPC UA integration |
| Offline mobile app on the shop floor | depends on vendor | designed for your dead zones |
| Annual maintenance | included in subscription | 12 to 18% of initial cost |
| Data portability | export often limited | complete |
For 25 users (technicians, shift leads, quality, engineering), a vendor subscription reaches $16,500 to $39,000 a year. Over five years, the gap with custom shrinks sharply.
| 5-year total cost (25 users) | Entry-level vendor | High-end vendor | Custom |
|---|---|---|---|
| Setup | $11,000 | $27,000 | $71,000 |
| Annual licences or maintenance | $16,500 | $39,000 | $11,000 |
| Food safety and sensor modules | $9,000 | $16,500 | included |
| Hosting | included | included | $2,600 per year |
| 5-year total | $102,500 | $238,500 | $139,000 |
The food safety requirements that tip the balance
IFS Food version 8, BRCGS and FSMA-aligned programmes all require documented maintenance control: preventive plan, intervention records, foreign-body checks after work, food-grade lubricants and validated release back to production. An off-the-shelf CMMS handles the preventive plan well. It handles less well the link between an intervention and the batches produced right after it, which is exactly what an auditor asks for after a non-conformity.
A custom CMMS can block a line restart until the "parts and tools counted" check is signed, attach the intervention automatically to ERP batch numbers and produce the audit file in one click. On the sensor side, connecting 30 measurement points (pump vibration, freezing tunnel temperatures) moves you from calendar-based to condition-based maintenance, the main source of the 20 to 35% gain.

James, maintenance manager at a ready-meals plant in the English Midlands (180 assets, 3 shifts, 22 users), runs at 6% unplanned downtime, about $520,000 of annual losses. He chooses a custom CMMS at $79,000, with 30 sensors at $275 each ($8,250) and $10,000 of annual maintenance.
After twelve months, unplanned downtime falls to 4.2%, a 30% drop worth about $156,000. First-year investment: 79,000 + 8,250 + 10,000 = $97,250. The project pays back in roughly 7.5 months of savings, and the next food safety audit passes with no finding on the maintenance chapter.
FAQ
Is an off-the-shelf CMMS enough for IFS or BRCGS?
Yes for the preventive plan and history, which cover about 70% of expectations. Automatic batch linking and post-intervention checks often require $9,000 to $16,500 of extra modules or development.
How long does a custom CMMS take to deploy?
Allow 4 to 7 months: 4 to 6 weeks of scoping with the teams, 3 to 4 months of development, then 4 weeks of data migration and training for the 3 shifts.
Can we start with a vendor and switch to custom later?
Yes, if the vendor allows a full export of the history. Check that clause before signing, because a poorly prepared migration costs $5,500 to $13,000 of manual rework.
What gain can sensors deliver?
On critical assets (pumps, compressors, cold tunnels), condition-based maintenance cuts breakdowns by 25 to 40%. Plants usually start with 20 to 40 measurement points, i.e. $5,500 to $13,000 of hardware.
Who owns the code of a custom CMMS?
With a well-drafted contract, the plant owns the source code and the data. Ongoing development is then negotiated at 12 to 18% of the initial cost per year.
