How to compare industrial equipment quotations

A quotation is a description of a project as the supplier understood it. Two suppliers reading the same enquiry can produce documents that differ by 40% in price and still both be honest, because one included installation, commissioning, spares and a delivered Incoterm and the other did not.

Comparison therefore has two phases. Phase one is normalisation: making the documents describe the same project. Phase two is evaluation: judging engineering fit, risk and total cost. Buyers who skip phase one are not comparing suppliers — they are comparing scopes.

• Nominal capacity versus guaranteed capacity — only the guaranteed figure has contractual value.
• The product basis the capacity is guaranteed on, including input material quality.
• Operating hours assumed per day and per year.
• Efficiency, uptime and yield assumptions behind the throughput figure.
• Whether a performance test with remedies is offered, and on what criteria.

• Major machinery, and its make and origin.
• Auxiliary machinery: dosing, buffering, cleaning, waste handling.
• Conveying and transfer between stages — a classic gap between two suppliers' boundaries.
• Storage, silos, tanks and buffers.
• Controls, integration, SCADA and who owns the software licences.
• Safety systems, guarding and compliance marking.

Utility figures are the difference between a capital comparison and an economic one. Over ten years, energy alone often exceeds the purchase price of the line. A quotation with no consumption data cannot enter a total-cost comparison at all.

• Installed power and realistic average consumption per unit of output.
• Water consumption and effluent produced.
• Steam, gas and compressed air demand.
• Cooling or refrigeration duty and the ambient design condition assumed.

• Engineering: layout, P&ID, electrical design, and how many revisions are included.
• Installation: supervision days versus full installation with labour and tooling.
• Civil works and foundations, and who provides the loading data.
• Electrical works from the panel to the machine.
• Commissioning duration and who supplies raw material for it.
• Performance tests, acceptance criteria and remedies for shortfall.
• Training: hours, participants, language and location.

Convert every offer to a single Incoterm before comparing anything.

• Warranty duration, and whether it covers parts only, or parts, labour and travel.
• Spare parts: commissioning spares, recommended two-year spares, prices and lead times.
• Service: response time, regional presence, remote diagnostics, cost per intervention.
• Lead time, and whether it starts at order or at approved drawings.
• Payment milestones — a 40% advance at a lower price can cost more than a 10% advance at a higher one.
• Written exclusions list. A quotation without one is incomplete.

• Annual energy cost at your tariff and your operating hours.
• Planned maintenance cost and required interventions per year.
• Labour requirement at the quoted automation level.
• Consumables: filters, belts, blades, lubricants, packaging materials.
• Spare-parts cost over five years and single-source part risk.
• Expected equipment life and residual assumptions.

1. Equalise the scope. Add every excluded item back into each offer at a realistic cost so all offers describe one project.
2. Equalise the basis. Convert to one Incoterm, one currency and one guaranteed capacity basis.
3. Mark the unknowns. Anything not stated in writing becomes a clarification question, never an assumption.
4. Run one clarification round. Send all suppliers the same questions with the same deadline. Response quality is itself decision data.
5. Build the total-cost view. Add five-year and ten-year running cost to the equalised installed cost.
6. Score non-price factors separately. Engineering fit, references, service coverage and acceptance regime, kept apart from price so neither hides the other.

• Structured RFQ builder — turns product, capacity and country into a supplier-ready request.
• RFQ readiness score — shows which scope information is still missing before you send anything.
• Supplier proposal comparison tool — normalises up to three offers across fifteen criteria and flags silent exclusions.
• Should-cost calculator — an independent CAPEX benchmark before offers arrive.
• Financing pathway screening — indicative only; approval always sits with the independent financing institution.

• Before you request quotes — what to define so quotations arrive comparable.
• Hidden costs in industrial machinery quotations — the fifteen line items that appear after award.
• What turnkey actually means — why two 'turnkey' offers can differ by millions.
• Supplier proposal comparison tool — run the comparison interactively.
