Short answer: स्टॅम्प केलेले भाग quote revisions should be controlled like engineering records. Each quote revision should state the drawing revision, changed assumptions, tooling scope, material and finish basis, inspection scope, annual volume, delivery terms, validity date, and buyer approval status. Without a quote history, teams may compare prices that were based on different parts or different risk assumptions.
A stamped part quote often changes several times before purchase order release. The drawing may change, volume may move, plating may be added, tooling ownership may be clarified, or inspection may become stricter. If the quote history is not controlled, the buyer can approve the wrong cost basis.

What each quote revision should record
| Revision field | Why it matters | Example control |
|---|---|---|
| Drawing basis | Price may be tied to a different geometry or tolerance set. | Quote Q3 based on drawing Rev B, not Rev A sample photo. |
| Tooling scope | Die type, sensors, spare inserts, and ownership change upfront cost. | प्रोग्रेसिव्ह डाय with two spare punches and buyer-owned tooling. |
| Commercial basis | Material, finish, currency, freight, and annual volume affect comparison. | 304 stainless, passivated, 50,000/year, EXW or delivered terms. |
| Open assumptions | Unresolved items become later change orders or delays. | Packaging trial and CMM report scope still pending buyer approval. |
Do not compare quotes without the basis
A lower price may simply exclude a finish, packaging method, dimensional report, spare tooling, or tighter feature. Quote revision control makes the comparison fair. It also protects the buyer when purchasing, quality, and engineering are reviewing different versions of the same project.
For tooling changes, record whether the revision changes inserts only, strip layout, stations, die size, press tonnage, or a full tool rebuild. Use the tooling tryout and sample approval guide when revised quotes affect the sample approval path.
Separate engineering changes from commercial updates
A quote can change because the part changed, or because the commercial basis changed. Material price, freight route, currency, MOQ, blanket order size, and inspection frequency can change price without changing geometry. Keep these differences visible so engineering does not approve a commercial update as if it were a part revision.
When a quote is revised after samples, include the sample result and disposition. A failed flatness result, burr complaint, or plating defect may drive extra process control. That cost should be tied to the evidence, not hidden as a generic price increase.
For पुरवठादार comparison, keep quote revisions linked to the quote तुलना मार्गदर्शक and landed cost guide. This helps the buyer separate a true cost reduction from a quote that moved freight, inspection, or tooling out of scope.
RFQ details to include
- Quote revision number, date, buyer contact, पुरवठादार contact, drawing revision, file list, sample reference, and change summary.
- Unit price basis: material, thickness, finish, tolerance scope, annual volume, MOQ, release size, currency, freight term, and quote validity.
- Tooling basis: die type, tool ownership, spare parts, sensors, tryout loops, sample quantity, maintenance responsibility, and change order rule.
- Quality basis: FAI, PPAP, dimensional report, material certificate, control plan, gauge need, CMM requirement, and inspection sample size.
- Packaging and logistics basis: carton, tray, label, barcode, export documents, delivery destination, लीड टाइम, and partial shipment rule.
- Open assumptions, pending buyer approvals, exclusions, and what triggers a new quote revision.
How to compare पुरवठादार answers
A strong पुरवठादार answer explains what changed from the last quote. A weak answer sends a new price without revision notes. Ask for a simple comparison table showing previous basis, new basis, cost impact, and items still open.
If multiple suppliers are bidding, normalize the quote basis before ranking. Tooling ownership, inspection documents, packaging, and freight can change the true landed cost more than a small unit-price difference.

FAQ
Why should stamped part quotes have revision numbers?
Revision numbers show which drawing, volume, finish, tooling scope, and inspection assumptions were used for each price.
What causes a stamping quote to change?
Common causes include drawing changes, material updates, finish changes, tighter tolerances, new inspection documents, packaging changes, freight, or volume changes.
How should buyers compare two quote revisions?
Compare the drawing revision, tooling scope, material and finish basis, quality documents, packaging, delivery terms, annual volume, and open assumptions.
What should be sent for a quote revision review?
Send the previous quote, new drawing revision, change summary, target volume, finish updates, inspection needs, packaging changes, and approval deadline.
