Your repeat order for display stands is already in production when your retail team requests a wider base. The China supplier quotes a change fee plus the full price of new bases. Its message says that material has been bought, but does not say whether the uncut sheets can still serve the wider design. Before approving the extra payment, ask for a priced explanation of the change and the material left behind.
The stands and quotation are fictional illustrations, not customer transactions or standard supplier terms. This article offers general information, not engineering, legal, accounting, tax or investment advice. Qualified advisers must review the actual contract, material suitability and commercial documents. A requested design change does not itself authorise a production stop or establish a right to recover costs.
Establish what was authorised before the request
Retrieve the accepted order, drawing revision, price and production approval. Record when the buyer requested the change and what the seller confirms had happened by then. Distinguish material ordered, material delivered, parts cut and assemblies completed. A statement that production started does not identify the cost of each affected operation.
Use the drawing-revision guide to fix the old and proposed specifications. Have the responsible technical reviewer identify precisely which parts change. Do not ask the factory to replace unaffected components merely because the drawing receives a new revision number.
Ask the seller what work it proposes to pause, continue or segregate while the change is considered, and obtain the required agreement. Your team's internal approval hold does not amend a contract or suspend an existing payment obligation.
Ask for a delta quote with supporting quantities
Request a breakdown tied to the affected order: earlier purchases, completed work, cancellation charges, proposed rework, new material and extra operations. Ask which amounts are already included in the original goods price and which are additional. Supporting records can be redacted for unrelated commercial information, but should still identify the relevant material, quantity and commitment.
For the stands, ask whether the uncut sheets meet the wider-base requirement. Have a competent reviewer assess suitability rather than infer it from a photograph or the supplier's assurance. Separate a reusable sheet from a cut base that cannot be reworked safely.
An editorial comparison might look like this:
| Quote item | Question to resolve |
|---|---|
| Purchased material | What quantity belongs to this order and was already funded? |
| Work in progress | Which operations were completed against the approved revision? |
| Reusable portion | Where can it be used, with whose technical approval? |
| Cancellation charge | What commitment and supporting charge does it cover? |
| Scrap or disposal | Which goods, proposed handling and authority are involved? |
| Replacement material | What genuinely new quantity and cost are required? |
| Revised payable | How do original charges, credits and extra charges reconcile? |
These are negotiation fields, not a cost standard or proof that a charge is legally due. Your buyer needs enough detail to compare accepting the change with continuing the approved design. The cheapest apparent option may still require a technical review.
Decide what happens to material you pay for
Agree custody, identification, permitted use and access for old material that remains usable. A fee labelled “material loss” is hard to explain if the same stock then enters your next order at full material price. Ask the seller how reusable value affects the quote and future charges; do not invent a unilateral deduction.
The unused-packaging guide addresses a related stock-custody problem. Here the record concerns material affected by a post-start change. Identify whether it remains with the supplier, is reworked, returned or disposed of, and who bears storage or handling costs under the agreement.
Do not assume paying a surcharge transfers ownership of every offcut or cancelled purchase. Have counsel review the proposed rights, especially where material serves several buyers. Obtain authorised disposal and appropriate safety review where required; do not direct unapproved reuse of an unsuitable part.
Accept the change before funding the extra work
Article 29 of the CISG text addresses agreed contract modification and written-modification provisions. Counsel must assess applicability, declarations and the form required by your actual agreement. It does not validate a supplier's surcharge or make the buyer's requested change binding by itself.
Have authorised representatives confirm the new revision, affected quantity, agreed cost adjustment, remaining old stock, payment milestones and revised delivery arrangements. Record which obligations remain unchanged. If the parties cannot agree, obtain advice on the existing order rather than treat the proposed quote as an accepted replacement.
Keep the original invoice and any supplementary or corrected document with their history. The ITA document guide distinguishes commercial invoice and packing-list purposes; it is US exporter guidance, not a universal document checklist. Ask the accountant and broker which records fit the actual goods and charge.
Give finance an additional amount, not a duplicate order
Compare the agreed adjustment with payments already credited to the original order. The second-invoice guide helps establish whether a document replaces an earlier request or asks for genuinely additional money. Mark superseded instructions without erasing them.
If a payment provider is involved, submit the approved documents and resulting payable amount for review. Ask about the proposed payment before funding. A payment receipt cannot establish whether uncut stock was reusable or whether the surcharge was reasonable.
Use pay an invoice to enquire with A2vanta about the agreed supplier payment. Your buyer, technical reviewer and seller resolve the change price and material custody; A2vanta does not approve drawings, audit factory costs or settle the dispute.
