What an OEE system really costs: the 3-year calculator
A price per machine is one line of the bill. Devices, sensors, operator screens, installation, integration, training and your own team’s hours decide what you actually pay. Put two offers on the same basis and see the difference before you sign.
Compare two offers
The example values are illustrative, not any vendor’s price. Replace them with the figures from your quotes and enter every amount in the same currency.
Your plant
Offer A
Example: subscription per machine, devices rented, self-installed.
Offer B
Example: lower subscription, devices bought, installation and training included.
·
Total = one-off costs + term × 12 × (subscription × billed units + device rental × devices) + term × other fees + internal hours × hourly cost. Devices = machines ÷ machines per device, rounded up. Year-one cash out leaves out internal time.
The cost lines a price list leaves out
A published OEE price often covers the software licence only. Ask every vendor to price the same scope line by line, and check who carries each of these costs.
| Cost line | Why it matters | Ask every vendor |
|---|---|---|
| Signal pickup and sensors | A machine without a usable signal needs a sensor, cabling or a PLC connection before it can report. | Which of our machines need new sensors or wiring, and who installs them? |
| Data devices or gateways | Devices can be rented, bought or included. How many you need depends on how many machines one device connects. | How many devices for our machines, bought or rented, and what happens to them if we stop? |
| Operator screens | Stop reasons are entered on a screen at or near the line, and many offers exclude the screens. | Are screens, tablets and mounts included, and which models are supported? |
| Network | Devices need Wi-Fi, Ethernet or mobile data on the shop floor. | What network do the devices need, and is a SIM or router included? |
| Installation | Self-installation saves money but costs internal hours. On-site work is often quoted separately. | Is installation remote, on-site or done by us, and what does an on-site day cost? |
| Integration | Connecting to ERP, MES or BI tools is usually a separate project. | Which integrations are standard, which are quoted, and at what rate? |
| Training and language | Operators adopt what they understand in their own language. | In which languages are the software, the training and the support? |
| Support | Hours, time zone and channel decide how fast a stopped line gets help. | What are your support hours in our time zone, and in which language? |
| Tiers and minimums | Some offers require every licence on the same tier or reserve multi-site features for the top tier. | Can we mix tiers, and which tier do we need for several plants? |
| Term and price protection | Multi-year terms lower the monthly price but lock the budget. | What is the price for 1 and 3 years, and how are renewals indexed? |
| Exit | Data and hardware must come back cleanly if you change supplier. | Can we export all raw data, and what happens to the devices at the end? |
Four price structures you will meet
Easy to compare, but the total grows with every machine, and devices or sensors are often billed on top.
Flat fees reward monitoring many machines at once. Check what counts as a line and what happens when you add one.
More cash in year one, less every month after. Check the device warranty and who replaces a failed unit.
Licence, integration and services priced together, with a wider scope and a longer lead time than a first monitoring step.
Free trial or paid pilot: what each really costs
A free trial is free on the invoice, not in hours: someone still installs, configures, trains operators and reads the data. A paid, supervised pilot on one line costs money but should come with a baseline, agreed success criteria and a decision date. Whichever you choose, write down before you start the result that would make you buy and the result that would make you stop.

Questions
- How much does OEE software cost?
- OEE systems are priced per machine, per line, per plant or per project, so a single monthly figure is not comparable across offers. Ask each vendor for the total cost of the same scope over the same term, with every line item listed, then compare the totals and the cost per machine per month.
- What is usually not included in an OEE software price?
- Often left out: sensors and cabling, data devices or gateways, operator screens, network equipment, installation, integration with ERP, MES or BI, training, higher support tiers and the time your own team spends.
- Is a free trial cheaper than a paid pilot?
- Not always. A free trial still uses your team’s hours for installation, configuration and follow-up. A paid, supervised pilot should include a baseline, success criteria and a decision date. Compare both on the hours they need and the decision they let you make.
- Should I compare an OEE system with an MES?
- Compare them on the scope you need in the next 12 months. An MES covers orders, materials, quality and traceability and is usually priced as a project. An OEE monitoring system covers machine states, stops, speed and counts and is usually the lighter first step.
- Which currency should I use in the calculator?
- Any, as long as every amount is in the same currency. The calculator does not convert currencies.
