An aluminum window RFQ should give every supplier the same opening schedule and identify the information needed to compare offers. Include dimensions, operation, glass, finish, performance requirements and delivery scope. Ask bidders to state exceptions clearly rather than hiding them behind a general claim of compliance.
Send each bidder the same opening schedule, drawings, performance requirements, glass and finish information. Require exclusions and substitutions to be stated. Lump-sum comparisons are weak when quantities and interface work differ.
Approve capability evidence, finish and hardware samples, then coordinated shop drawings. For larger orders, define production inspections and document checks before shipping. Keep approvals tied to revision numbers.

Include packaging, freight, duties, unloading, storage, access equipment, installation, testing and damage response. Lowest ex-works price is not necessarily lowest installed cost.
A trading company, fabricator, system house and installer may control different parts of the order. Confirm the legal entity, factory role and responsibility for design, glass, hardware and installation information.
Ask for relevant test or certification documents, material and finish data, sample units and project-specific shop-drawing capability. Verify that evidence applies to the proposed product and size.
Use a sample request and drawing review to evaluate response quality, revision control and technical clarity. Confirm capacity, lead-time basis, packaging, claims and spare-part support.
Assign an ID to each opening and keep that ID on drawings, quotations and packing lists. If one bidder changes an operator type or glass package, place the change beside that opening instead of accepting a footnote covering the whole order. For a bulk or export order, also agree sample approval, labeling, packaging, replacement parts and the process for reporting shortages.

They should describe the same openings, configurations and service scope. Resolve substitutions, missing performance evidence and delivery exclusions before comparing totals. Keep a written record of the supplier's final response.
Use the checks above to mark the unresolved items on your drawing or quotation. Send that marked-up version with the selected product reference so the next discussion can focus on the actual configuration.
