Custom machinery quotations: how to compare them
Custom machines are never quoted like-for-like. Normalise scope first, then compare risk, acceptance terms and total cost.
Short answer
Why can't custom quotations be compared directly?
Each builder interprets the requirement through its own design, so quotations differ in what is included. One may include tooling, guarding and installation; another may list them as options.
- Machine and auxiliary equipment actually included
- Controls, software licences and HMI language
- Change parts and tooling for every format
- Installation, commissioning and training days
- Documentation, CE/UL marking and spare parts
What acceptance terms should you compare?
The quotation should state measurable FAT and SAT criteria: output, uptime over a test run, reject rate and format changeover time. Vague terms such as "to buyer satisfaction" leave you without leverage.
How should payment milestones be structured?
Tie payments to verifiable events — design approval, passed FAT, delivery, passed SAT — rather than calendar dates. A large advance with little retention shifts risk to the buyer.
What belongs in total project CAPEX?
Add freight, duties, installation, utilities connections, foundations, integration with upstream and downstream equipment, and your own engineering time. Compare builders on this total, not the machine price alone.
Quick questions
Should I pick the cheapest custom machinery quote?+
Only after its scope matches the others. Missing items usually return later as change orders.
How many builders should quote?+
Three to five qualified builders is usually enough to compare designs without overloading your team.
Can one builder's design be shared with others?+
Not without permission. Share your requirement, not a competitor's proprietary design.
Summary
- Normalise scope before comparing prices
- Compare measurable FAT/SAT criteria and payment milestones
- Decide on total project CAPEX, not machine price
