| Product and application fit | Equipment type, intended operation, operating environment, and configuration offered. | Confirm that each quotation covers the same application, operating conditions, and scope of supply before comparing price or lead time. | Technical proposal, equipment list, configuration drawings, and a written statement of design assumptions. |
| Rated capacity and operating limits | Applicable ratings and limits for the quoted configuration, such as load, pressure, torque, speed, or flow, where relevant. | Compare like-for-like ratings and check that the stated values apply to the complete offered configuration, not only an individual component. | Datasheets, rating plates or sample layouts, calculations where applicable, and test records tied to the model or serial number. |
| Applicable standards | Standards and editions specified for the equipment and its intended use. | Check the exact standard, edition, product scope, and certification status. A general quality-system certificate does not by itself certify every product. | Current certificates and scope statements; verify certification details with the issuing organization or its official directory where available. |
| Quality management | Documented controls for design, purchasing, production, inspection, nonconformities, and corrective actions. | Compare the processes and their applicability to the quoted product. ISO 9001 is a quality management system standard, not a product performance rating. | Certificate with scope and validity details, inspection and test plans, sample inspection records, and documented corrective-action procedures. |
| Materials and traceability | Material specifications, component identification, and traceability arrangements for safety-critical parts. | Check whether records can link supplied materials and components to the finished equipment and its serial or batch identification. | Material certificates where specified, heat or batch records, component lists, and traceability samples. |
| Testing and inspection | Factory acceptance testing, functional checks, dimensional inspection, and other tests required by the purchase specification. | Agree on test methods, acceptance criteria, responsible parties, and witness or hold points before production is complete. | Approved inspection and test plan, calibrated-instrument records where applicable, signed test reports, and punch-list closeout. |
| Manufacturing capacity | Production facilities, relevant equipment, available production slots, and planned delivery schedule. | Assess capacity against the requested quantity and delivery date. Distinguish demonstrated production capability from an unverified maximum claim. | Production schedule, facility or process overview, milestone plan, and references for comparable equipment supplied, subject to customer permission. |
| Delivery and export readiness | Quoted lead time, packing method, shipping dimensions and weights, export documentation, and delivery terms. | Compare the same delivery basis and include inspection, approvals, packing, and shipping preparation in the schedule. | Written delivery schedule, packing specification, shipping data, and a clear list of included and excluded costs. |
| Warranty and spare parts | Warranty duration and coverage, exclusions, recommended spares, and parts availability arrangements. | Compare coverage in writing and check whether replacement parts and technical support are available for the expected service period. | Warranty terms, recommended-spares list, parts catalogue, and stated process for warranty claims. |
| Technical and after-sales service | Support channels, service languages, working hours, response commitments, and availability of field service. | Compare documented commitments rather than general assurances; clarify travel, labor, and remote-support costs. | Service-level terms, escalation contacts, service capability overview, and written response-time commitments. |
| Commercial comparison | Price, payment milestones, exclusions, commissioning, training, and optional items. | Normalize quotations to the same technical scope, inspection requirements, delivery basis, and service coverage before ranking total cost. | Itemized quotation, assumptions and exclusions, payment schedule, and a scope-compliance checklist. |
| Reference and risk checks | Relevant project history, customer references, product changes, and identified supply-chain dependencies. | Validate references independently where possible and assess whether experience is relevant to the specific equipment and operating conditions. | Permission-based customer references, project summaries, risk register, and documented change-control process. |
