CMMS vs MES: what a small manufacturer actually needs.
A CMMS keeps your equipment running. An MES runs your production. Most shops are told to pick one, then either go without production visibility or buy a system they cannot afford to run. Here is how the two compare, and where vMaint fits between them.
| Traditional CMMS | vMaint | Full MES | |
|---|---|---|---|
| What it manages | Maintenance: work orders, preventive maintenance, parts, asset history | Maintenance, production, and floor coordination, in one app | Production: orders, scheduling, quality, traceability |
| Pricing | Per user, about $20 to $75 a user per month | Flat per site, whole team included. $200 to $600 a site per month | Per machine or per site, often $900 a month and up, plus hardware |
| Setup and hardware | 1 to 4 weeks, no shop-floor hardware | Same day. No hardware for the core; gateways only if you add machine data | 6 to 18 months, plus gateways and edge hardware per machine |
| Who is included | Paid named seats; requesters often free | Your whole team: operators, leads, technicians, managers | Usually site-licensed, varies by vendor |
| Production, OEE, downtime | No | Live OEE, downtime with reasons, output vs target | Yes, this is its core |
| Machine data (SCADA / IoT) | Rarely native | Optional, set up and quoted per shop | Yes, deep but heavy to deploy |
| AI | Limited, varies by vendor | Reads manuals and fault history, opens work orders, shows downtime cost | Varies by vendor |
| Data location | Mostly cloud only | Cloud, or on-prem and edge so machine data stays on site | Cloud or on-prem |
| Best for | Maintenance-only teams | Small and mid-sized shops that need maintenance and production visibility | Large plants with the budget and IT to run full production control |

What a CMMS does, and its blind spot
A CMMS keeps equipment running. It digitizes work orders, schedules preventive maintenance, tracks spare parts, and stores asset history. Tools like MaintainX, UpKeep, and Fiix do this well and are easy for technicians to use on a phone. What they do not do is watch production. They do not measure OEE or split losses into availability, performance, and quality, and most have no native link to a PLC, so a machine stopping does not inform a work order. For a maintenance-only team that is fine. For a shop that also wants to know why the line is slow, it is a blind spot.
What an MES does, and why it is heavy for a small shop
An MES runs the production process: it routes orders, schedules the floor, enforces quality checks, captures real-time machine data, and tracks material genealogy for traceability. That power comes at enterprise scale. Full suites commonly run into the high six or seven figures, and even mid-tier systems take a year or more to deploy before OEE improves, with per-machine gateway hardware on top. It is the right tool for a large, regulated, or high-mix plant with IT staff to run it, and overkill for most small shops.
Where vMaint fits
vMaint is one app that does the maintenance job and the production job. You get work orders, PM, and parts like a CMMS, plus live OEE, downtime with reasons, and output vs target like the production layer of an MES, plus coordination tools for operators, leads, technicians, and managers. Machine integration is optional and quoted per shop, so you can start with no hardware and add SCADA or IoT later. Pricing is the honest difference: a CMMS charges per user, an MES charges per machine plus a long rollout, and vMaint is flat per site with the whole team included. It is early-stage, built by a founder who has worked as a machine operator, maintenance technician, and automation engineer, so it is leaner than a fifteen-year-old MES suite. The trade is straightforward: production visibility a CMMS lacks, at a fraction of MES cost and complexity.
Which do I actually need?
If your problem is “machines break and maintenance is chaos,” you need CMMS capability. If your problem is “I cannot see what the line is actually producing,” you need production visibility. Many shops need both, which is the gap vMaint fills.
Common questions
What is the difference between a CMMS and an MES?
A CMMS manages maintenance: work orders, preventive maintenance, assets, and spare parts. An MES manages production: machine output, downtime, and OEE. They answer different questions, so most manufacturers buy both. vMaint does both jobs in one app.
Do I need a CMMS or an MES?
If your problem is that machines break and maintenance is chaos, you need CMMS capability. If you cannot see what the line is actually producing, you need production visibility. Many small shops need both, which is the gap vMaint fills.
Can one app replace a CMMS and an MES?
Yes. vMaint runs maintenance and production from the same system, priced flat per site, so a small plant gets both without buying and integrating two separate tools.
