Cancelling a supplier order does not establish the saving

The order is removed from the site plan
Suppose cash is tight and you decide a planned purchase can be cancelled. The job schedule is updated, and the forecast removes the entire supplier payment. Nobody has checked whether the supplier has accepted the cancellation or incurred costs already.
Separate the operational decision from the financial result. Taking an item off your internal plan does not by itself establish what the supplier is still entitled to receive.
Locate the order and relevant terms
Find the accepted quotation, purchase order, deposit record and correspondence about the goods. Identify the cancellation provisions and any uncertainty about what was agreed.
business.gov.au's contract guidance encourages clear descriptions of the work, payment arrangements and relevant terms. Use the actual documents to frame the enquiry rather than assuming an unused item can always be cancelled without cost.
Ask about the supplier's current position
Request confirmation of production, procurement and dispatch status, together with the supplier's response to the proposed cancellation. Ask it to identify any amount claimed and its basis.
Do not present the supplier's first figure as automatically correct or automatically invalid. If the amount or contractual position is disputed, keep it visible and obtain appropriate advice before agreeing a settlement.
Distinguish deposit treatment from future payments
Record whether any deposit is refundable, applied to an agreed charge or still unresolved. Check when any confirmed refund is expected rather than treating a possible credit as cash already in the bank.
Reconcile the cancellation with the ledger so the deposit and unpaid balance are not both removed incorrectly. Have the accountant review entries where the treatment is unclear.
Update the forecast with supported figures
Replace the original payment assumption with the amounts and dates now supported by the information available. Label unresolved charges and potential refunds separately, and test their effect on the cash shortage.
Also consider replacement or delay costs if the job still needs an alternative. Cancelling one purchase may shift the cost to another date or supplier rather than remove it entirely.
Close the cancellation in writing
Retain the agreed cancellation outcome, remaining payment obligations and any refund confirmation. Assign someone to check that the expected credit or money is actually received.
Before using the apparent saving to promise another supplier payment, make sure the financial consequences are understood. A cancelled order becomes a reliable cash adjustment only when the remaining commitments and timing have been assessed.
