Make every supplier price the same scope.
An elevator cab material RFQ gets comparable quotes when every supplier prices the same released scope: the governing drawing revision, exact quantity and unit, material and finish, required fabrication, packaging, delivery point, need date, and requested validity period. State tolerances, edge conditions, and grain direction wherever they affect yield or workmanship.
Published
A useful RFQ is a controlled package, not a request to “price the stainless.” It lets a supplier trace each amount to a technical basis and lets the buyer prove what was included later. The RFQ line identity should also match the estimating takeoff or elevator cab bill of materials line that will ultimately consume it.
Log questions and assumptions in writing. Issue scope-changing clarifications to every bidder against an identified RFQ revision. Require one compliant base, separate alternates, identified exceptions, and a validity date. A blank should mean “not answered,” never zero cost or included.
Name the job, RFQ line, governing drawing number, revision, and issue date. Attach every referenced specification. Label a pre-release request budgetary and identify unresolved inputs.
State usable quantity and the quote unit: each, sheet, length, area, set, or lot. Identify spares or waste and ask for the actual buy quantity after minimum constraints.
Give material, governing size, finish, approved sample or source, and relevant grain direction. State tolerances, edge conditions, protection, cutouts, forming, welding, polishing, and other required processing.
Define protective packaging, job marking, delivery point, known access constraints, and the required arrival date. Separate shipment from arrival and state whether freight is included, added, collect, or excluded.
Request unit and extended price, setup, minimum order, applicable taxes, payment terms, validity, fulfillment timing, and exclusions. Keep alternatives separate from the compliant base quote.
Suppliers optimize around different stock formats, equipment, freight arrangements, and commercial policies. Their totals can differ even when the usable result is equivalent. Conversely, similar totals can hide different finishes, yield, processing, packaging, or delivery scope. Normalize the quote to the quantity and condition the shop actually needs, while preserving the original offer unchanged.
| Line element | Why displayed prices differ | How to normalize it | Evidence to retain |
|---|---|---|---|
| Unit and quantity | One offer is per sheet or length; another is per finished piece, area, set, or lot. | Convert to the released consumption unit and compare the extended buy quantity. | Original unit, conversion basis, dimensions, quantity, and rounding rule. |
| Minimum order | The unit rate looks low, but the required purchase exceeds the job quantity. | Compare the actual extended commitment and identify usable excess separately. | Minimum quantity, pack or mill condition, and treatment of surplus. |
| Sheet or mill yield | Suppliers nest parts differently or assume different stock availability and grain orientation. | Validate yield against part sizes, required grain, defects, trim, and supplied stock format. | Yield calculation, nesting basis, stock size, grain direction, and waste ownership. |
| Cutting and fabrication | One line includes cut-to-size parts, finished edges or forming; another supplies raw material. | Separate raw material from each required process and compare the same delivered condition. | Process list, tolerances, edge condition, drawings, and vendor exceptions. |
| Freight and packaging | Freight may be included, added later, collect, or based on a different destination or service. | Compare landed cost at the stated delivery point with equivalent protective packaging. | Freight terms, destination, service, packaging method, and quoted allowance. |
| Tooling and setup | Setup may be embedded in unit price, shown once, amortized, or omitted pending review. | Separate one-time and recurring charges and identify ownership and reuse conditions. | Setup description, tooling ownership, storage, maintenance, and repeat-order treatment. |
Keep the supplier's dated quote, attachments, terms, revisions, and correspondence unchanged. In a separate analysis, map offers to the same RFQ lines and document adjustments for unit conversion, buy quantity, freight, processing, tooling, and scope.
Show the original rate and every calculation to the evaluated amount. Have the responsible technical person validate yield. Label unknown freight unresolved rather than inserting an unsupported allowance.
Then run a compliance review before selecting on evaluated cost. Confirm material, finish, source restrictions, grain, dimensions, tolerances, fabrication, protection, required date, and all exceptions. Ask the supplier to correct ambiguity in writing. The buyer's interpretation is not a vendor commitment.
There is no universal validity period. Request a date covering the expected approval and purchasing decision, based on your shop's history. If the supplier cannot hold material, finish, freight, or processing inputs that long, record the shorter period as commercial exposure.
Quote validity and fulfillment timing are different. A price can remain valid while stock availability changes, and an available item can be repriced after expiration. Put both into cab lead-time tracking: the deadline to commit at the quoted basis and the acknowledged timing after an authorized order.
Treat the quote as historical evidence, not current authority to buy. Send the supplier the latest governing revision, quantity, destination, required date, and previous quote reference. Request written confirmation or replacement of price, validity, availability, fulfillment timing, freight, payment terms, exceptions, and any material allocation assumptions.
Do not ask only whether “the price is still good.” Compare the revalidated offer with the customer estimate basis. Identify who can accept changed exposure and whether the customer proposal needs an updated qualification.
Build It Track It supports estimates with a rate library, vendors and person-entered BOM lines today, along with job files, contacts, timelines, drawing revisions, change orders and the Final for Record lock. Purchasing and purchase orders, inventory, capacity, scheduling and delivery dates, production scheduling, installation, inspection and final payment, invoicing and accounting are planned for the Q3 2026 launch. An elevator manufacturing ERP system may hold later transactions, but the sourcing team still must define and validate the RFQ basis.
Single-source buying is appropriate when the approved finish or sample, proprietary process, matched lot, existing tooling, qualification history, or continuity requirement makes substitution impractical. Document that reason. Also identify the supplier dependency, revalidation trigger, and response if the source cannot meet the requirement.
Multi-source when the specification is transferable and equivalent output can be verified. Qualify alternates before a disruption and compare total usable scope. Splitting an order can introduce lot variation, duplicate setup, mismatched protection, or divided accountability.
Retain the issued RFQ package and revision, bidder list, every quote and revision, clarification log, technical compliance review, normalization worksheet, freight and yield basis, exceptions, validity date, selection decision, and approvals required by company policy. Link the selected quote lines to the estimate lines they support.
Preserve rejected alternatives when they explain the final basis. Label expired or budgetary quotes, unconfirmed freight, and expected yield as assumptions with owners. Another reviewer should be able to reconstruct the pricing basis without relying on memory.
A quote is the supplier's offer to provide defined goods or services under stated prices, dates, terms, qualifications, and validity. Receiving it does not authorize work. Using it in an estimate does not reserve material unless the supplier explicitly says so.
A purchase commitment is the point at which an authorized action creates an obligation under the applicable terms. That could occur through acceptance, a deposit, a letter of intent, or another approved method, depending on company policy and the agreement. Buyers must know their authority limits and avoid informal instructions that suppliers can reasonably treat as authorization.
A released purchase order is the controlled purchasing document stating supplier, lines, revision, quantity, price, delivery, destination, terms, and authorization. It should resolve quote exceptions and reference the accepted offer. “PO pending” is neither a release nor permission to proceed. If early work is required, issue an authorized instrument that defines exactly what is committed and what remains excluded.
Include the line identity, governing drawing revision, quantity and unit, material and finish, relevant grain direction, tolerances, edge conditions, fabrication, packaging, delivery point, required date, and requested validity. Attach every referenced drawing and specification.
Convert each quote to the released BOM or takeoff unit while retaining the supplier's original unit. Account for minimum orders, yield, scrap ownership, processing, freight, and setup. Compare extended landed cost for the same usable scope.
One supplier may include cutting, finished edges, protection and freight while another prices raw sheets at pickup. Minimums, yield, tooling, packaging, exclusions, finish sources, and delivery can also differ. Resolve every qualification before comparing totals.
Request validity through the expected purchasing decision, but let the supplier state what it can support. Use your shop's approval and release history to set the request. Track validity separately from lead time; price validity does not guarantee availability.
Send the current revision, quantity, delivery requirement and prior quote reference, then request written revalidation of price, availability, freight, terms and validity. Record customer-price exposure and identify who must approve any commercial change.
Single-source when an approved finish, proprietary process, matched lot, tooling or continuity need makes substitution impractical. Multi-source when the specification is transferable and supply resilience matters. Qualify alternates before an urgent need.
No. A quote is an offer under stated scope, terms and validity. A commitment occurs through authorized acceptance under applicable terms. A released purchase order communicates the authorized scope, quantity, price, delivery and terms.
