The supplier raises the price after you accepted the materials order

The new price arrives after the order was placed

A hypothetical contractor accepts a materials quotation and later receives a supplier message announcing a higher price before delivery. The contractor has already quoted the customer using the earlier figure. Compare the order history and terms before accepting or rejecting the increase. A general price-rise announcement does not by itself explain what applies to this particular commitment.

Reconstruct the agreement sequence

Collect the quotation, validity wording, purchase order, acceptance and any acknowledgement or linked terms. Record dates and versions without assuming that the contractor's order and the supplier's acknowledgement necessarily say the same thing. Ask the adviser to identify any conflict or missing document. Do not rely solely on the latest invoice to explain the agreed price.

Check the change provisions

Business.gov.au recommends clear payment terms and written agreement to contract variations. Have the relevant pricing and change provisions reviewed against the actual correspondence. This article does not decide whether the supplier can increase the amount or whether an enforceable fixed-price contract was formed. Those questions depend on the documents and circumstances.

Ask what the supplier relies on

In the hypothetical example, request the basis, calculation and intended application of the increase. Clarify whether it concerns the ordered quantity, a changed specification, delivery timing or only future purchases. Keep the supplier's explanation with the original records. Avoid describing every difference as a price rise if part of it relates to additional goods the business requested.

Assess the delivery consequence with advice

Identify when the materials are needed and any practical alternatives, using supported quotes and availability information. Do not cancel the existing order or withhold payment on an assumed right without advice. Keep the customer contract separate: a supplier's higher demand does not establish that the contractor may pass the same amount on to the customer.

Record the resolved commercial position

If a change is agreed, retain the advised documentation and update purchasing, accounts and the project estimate consistently. If it remains disputed, confirm the next response with the adviser rather than letting staff follow conflicting prices. CRP can help organise the cost impact. The useful decision begins with what was actually ordered and accepted, before the business commits to the supplier's new figure.
