How much does machine monitoring cost? A practical buyer’s guide

The short answer: price follows the equipment and reporting scope

There is no reliable single per-machine price for every monitoring project. Ten identical machines with a confirmed interface can require a different integration effort from ten machines using several controllers, external sensors and manual output records. The machine count is a starting point, not a complete quotation.

A useful quote states what information will be collected, how it will be acquired, which reports are included and how the installation will be accepted. This guide explains the cost structure rather than publishing an unverified WhereFy rate card. Request a site-specific quotation for actual pricing, applicable taxes and commercial terms.

Hardware: what needs to connect to each machine?

Review gateways, input modules, sensors, power supplies, enclosures, installation materials and network equipment where they are needed. An available controller interface may reduce additional instrumentation, but it still requires verification. An Ethernet socket alone does not establish that the required production tags are accessible.

Ask whether hardware is shared across a machine group or dedicated to each asset, and which assumptions determine that arrangement. Record ownership, replacement responsibilities and any spares included. Compare the same equipment boundary across quotes instead of assuming that every gateway has the same capacity or function.

Software: compare the licence boundary and included functions

Ask what the licence covers: connected assets, users, sites, modules, deployment environment or another agreed measure. Confirm whether the fee is recurring or perpetual, and distinguish access to software from the support and upgrades included with it. Do not infer a supplier’s licensing model from the appearance of the dashboard.

Machine-state timelines, downtime reasons, OEE calculations, scheduled reports and integration with another business system are different requirements. Name the functions you need and the data they depend on. If reject counts are unavailable, paying for an OEE screen does not create the missing quality input.

Integration and commissioning: the work behind a usable report

The project may need controller mapping, state definitions, counter validation, shift calendars, product cycle times, dashboard configuration and operator input. These tasks determine whether the result explains production accurately. A connection that reads values is only one part of an operational reporting system.

Clarify site survey, travel, installation windows, electrical work, network responsibilities and customer dependencies. Specify how many report revisions or training sessions are included. A quote that excludes commissioning can appear cheaper until the team adds the work needed to use it.

Calculate ownership cost over the same period

Choose a comparison horizon, such as three years, and use the same period for every supplier. A planning model is: one-time hardware and implementation + recurring software, hosting and support over the period + agreed maintenance or change allowances. Avoid counting the same hosted service twice if it is already included in a subscription.

Keep taxes, payment terms, future expansion and optional modules visible in the comparison. A fixed allowance for every machine may be misleading when controller types differ. Ask how costs change if the pilot expands, a machine moves, a report changes or a connection must be revalidated after a controller upgrade.

Use a pilot to resolve uncertainty, not to hide the full scope

Select equipment that represents the controller and operating differences in the proposed rollout. A convenient demonstration on the newest machine may not establish the effort required for an older production line. Agree which uncertainties the pilot must answer and what evidence will be handed over.

Pilot acceptance can include a supervised count reconciliation, verification of running and stopped events, shift-boundary checks and the agreed behaviour when communication is lost. Ask which pilot deliverables carry forward to the rollout and whether any pilot charges are credited; neither should be assumed.

Keep cost and potential value as separate calculations

A monitoring system may reveal avoidable losses, but recovered capacity has value only when the business can use it. Start with a defined baseline and an operational improvement action. Do not treat every recorded downtime minute as recoverable production or every recovered hour as additional saleable output.

Compare the cost proposal with a transparent improvement case. Document the contribution assumptions, product mix and downstream constraints used in that case. The related ROI guide explains this evaluation in more detail; a supplier should not need an unsupported payback promise to explain the project scope.

What to send WhereFy for a scoped quotation

Provide the approximate machine count, machine and controller models, existing connectivity, required states and counters, shift structure and reports. Include the site location, preferred deployment requirements and whether you need a pilot or a full rollout. Photos of equipment labels can help identify models; do not share passwords or network credentials in the initial enquiry.

WhereFy Smart Insight and PLC–IoT integration can be discussed around these inputs. Ask the team to separate hardware, software, engineering, commissioning and ongoing services in the quotation, and to list assumptions, exclusions and acceptance criteria. That creates a proposal you can compare and review with production, maintenance and procurement.
