When Stone Requirements Change After Offers Arrive

Identify what has actually changed

Stone requirements can shift after suppliers start responding. An architect changes the finish, an installer requests a different thickness, or the delivery location becomes definite. Before comparing prices again, establish whether the offers still address your intended purchase. An offer prepared for yesterday’s specification cannot automatically be treated as a proposal for today’s requirement.

Write a short change note for your purchasing team. Describe the original requirement, the replacement requirement, and anything still awaiting a decision. Pay particular attention to stone type, dimensions, thickness, finish, quantity, and delivery conditions. The purpose is not to create a separate contract. It is to ensure everyone can explain the same purchase before asking suppliers to respond.

For example, asking a supplier to reconsider payment terms for the same stone and quantity may be an offer-level discussion. Replacing polished interior stone with a different finish for an exterior application changes the underlying requirement. That change may also affect production, packing, and shipment assumptions. Calling both situations a “price revision” hides an important distinction.

Separate an offer revision from a new requirement

Operated by Fusapp OÜ, MarbleMap is a commission-free, sealed-bid B2B request-to-offer marketplace for natural stone. Buyers see the offers submitted to their requests, while suppliers cannot see one another’s offers. Meaningful comparison therefore starts with a shared specification: each supplier should be responding to the same purchasing brief, even when their commercial terms differ.

If the requirement remains unchanged, you can use Request revision on the Offers tab to ask a supplier to revise its offer. You might ask for an existing delivery condition to be stated clearly or for payment terms to be reconsidered. Explain what should change and what must remain the same. This helps keep a commercial discussion from becoming an undocumented technical change.

If the stone, quantity, application requirement, or delivery scope changes, the issue extends beyond an individual offer. Negotiating a replacement specification with one supplier while keeping other offers on their original basis creates an uneven comparison. A lower total might reflect less material or a narrower delivery scope rather than a better commercial proposition.

A useful test is whether other suppliers would have proposed a different product, price, or delivery arrangement if they had known the new information. If so, prepare a new request. This gives the updated requirement a consistent starting point without treating price as evidence of material quality, delivery performance, or supplier reliability.

End the old sourcing round deliberately

On MarbleMap, a published request locks for editing when the first offer arrives. Edit demand disappears from the request page, and a lock notice explains that the request can no longer be edited. You cannot simply replace its specification and continue collecting offers against the revised text. Decide instead whether to close or cancel the old request.

Closing stops new offers while retaining the request and the offers already received for review. After an offer has arrived, use Close in the More actions menu beside the request in My Demands. The Close demand button on the request page is available only before the first offer. Closing is also appropriate when incomplete information needs replacing with a clean copy.

Cancelling serves a different purpose: you are abandoning that purchase and do not want an order to result from that request. Cancel demand appears on the request page once the first offer has arrived. Cancellation is irreversible, and a cancelled request cannot be reopened. Closing is also irreversible, and a closed request cannot be edited. Neither action is a temporary pause button.

If you only want to stop incoming offers, preserve the history, or prepare an updated copy, closing may be the better fit. If the old purchase has been abandoned entirely, consider cancellation. Read the confirmation before proceeding. When uncertain, distinguish stopping offer collection from ending the request completely rather than choosing whichever button is easiest to find.

Build a complete updated draft

To collect offers again after closing or cancelling, select Duplicate (new demand) from the request’s More actions menu in My Demands. The content is copied into a new draft that opens for editing. This does not reopen the old request. Suppliers can submit offers for the updated scope after you adjust and publish the new draft.

Review more than the sentence that triggered the change. Check the title, description, product lines, delivery information, pricing currency, and offer deadline together. If thickness changed in the description, make sure a product line does not retain the old dimension. If quantity changed, revisit the delivery plan. Consistency within the draft matters as much as the accuracy of each individual field.

Write the replacement request for a supplier who has never seen the previous discussions. “Same as before, different finish” is not a complete specification. State the current requirement in full and resolve outstanding decisions before publication where possible. Earlier offers may inform internal planning, but they are not prices or delivery commitments for the new scope.

Compare the new offers on a common basis

As responses arrive, check that each supplier has addressed the same stone, quantity, and shipment conditions. Separate included work from additional charges and clarify exceptions before deciding. A lower price alone does not establish quality or reliability. The buyer and supplier must confirm the specific stone, documents, quantity, shipment, and payment conditions. Payment does not pass through MarbleMap, and the platform does not provide escrow.

A new request also does not automatically amend an existing commercial agreement. If you have already moved into an order or made commitments with a supplier, distinguish the request’s platform status from those obligations. Treat the updated sourcing brief and any existing agreement as separate matters that need explicit attention.

Explore more buyer guides as you prepare your next purchase. When requirements change, define the difference, end the old sourcing round appropriately, and complete an updated draft. Publish once the scope is coherent, then compare offers that answer the same need rather than prices prepared for different specifications.
