You already have an ERP, and it offers a “maintenance” module. The question follows naturally: why pay for one more piece of software? The answer isn’t ideological, it’s practical. A CMMS and an ERP don’t serve the same job, and the right choice depends on who will actually use it day to day.
Two systems, two logics
An ERP manages the company as a whole: finance, purchasing, inventory, production, human resources. Its strength is accounting integration and the big picture. Its maintenance module is often an extension designed for management control, not for the technician.
A CMMS starts from the other end: the field. It’s built around the work order, the asset, the procedure, and mobility. Its strength is the daily execution of maintenance, not financial consolidation.
The deciding question: who will use it?
That’s the real test. An ERP module is made for trained office users at a desk. A maintenance technician is on the shop floor, sometimes with greasy hands, often without perfect network. If closing a job means navigating ten ERP screens, they won’t do it, and your data will be wrong.
A CMMS like Maint Vision puts maintenance in the phone: scan an asset’s QR code, run the procedure, take a photo, log the time. Field adoption is the precondition for reliable data, and that’s precisely where ERP modules fall short.
What a CMMS does better
- Structured preventive maintenance: calendar and meter-based plans, automatic work order triggers, reusable procedures.
- Mobility: an app built for the field, not a web portal reluctantly adapted.
- Maintenance requests: anyone can report a problem, even without an account, via a public QR code.
- Speed to launch: a dedicated CMMS deploys in weeks, whereas an ERP-module project often runs into months.
What an ERP keeps for itself
The ERP remains master of accounting, official purchasing, payroll, and the consolidated financial view. The goal isn’t to replace it, but to stop asking it to do a job it doesn’t do well.
The real point: integration
The right architecture isn’t “one versus the other” but “each in its role, connected”. The CMMS executes maintenance and produces field data; the ERP consolidates costs and purchasing. An open CMMS with an API exchanges with the ERP without forcing technicians to live inside software that was never built for them.
In short
If nobody actually uses your ERP’s maintenance module, it’s no accident: it wasn’t designed for the field. A dedicated CMMS doesn’t compete with your ERP, it fills exactly what it lacks.
