Separate required quantity from the supplier's purchase rule
Start with supported demand, usable stock and existing inbound commitments. Then identify the supplier's minimum order and required pack multiple. The difference is the stock purchased because of the commercial constraint. Show that excess explicitly so a lower quoted unit price does not conceal a much larger cash commitment.
Microsoft's default-order settings distinguish minimum, maximum, multiple and standard quantities. These are separate controls in purchasing and planning. Verify which one drives the proposed order and whether it reflects the current supplier agreement. An outdated default can create unnecessary inventory without anyone making a new buying decision.

Compare complete purchase alternatives
Request viable alternatives such as a smaller lot at a higher price, staged releases, mixed-product minimums or a different supplier. Include freight, setup charges and timing where they change the comparison. Use the actual payment schedule to assess cash, since a supplier may require a deposit well before the goods are available for sale.
In a hypothetical decision, expected demand is 600 units. Buying 600 at $8 costs $4,800; buying a minimum of 1,000 at $7 costs $7,000. The larger order saves $600 on the first 600 units but commits another $2,800 to 400 excess units. Whether that is attractive depends on how and when the remaining units can be sold or otherwise recovered.
Avoid calling the $1 reduction a guaranteed saving across the full purchase if some units may never sell. Keep the forecast quantity and the expected recovery value of surplus stock visible as assumptions.
Test the slow-demand and product-change cases
Model a slower sales path, a price reduction and a product change that makes old stock less attractive. Include storage, handling and any time-sensitive product restrictions. Show the date at which the larger purchase is expected to turn back into cash. An attractive product margin can coexist with a long period during which the business cannot use the money elsewhere.
Assess uncertainty by variant. A total minimum may be manageable while a minimum per size or color creates difficult leftovers. Use the forecast mix and current stock by variant rather than applying one average demand rate. Retain the evidence behind the purchasing team's confidence, including confirmed customer commitments where available.
Approve the quantity with a follow-up trigger
Document the chosen option, expected sell-through, cash dates and reasons management accepts the surplus risk. Ask the accountant to assess inventory carrying values under the applicable policy as evidence changes. The purchase decision's optimistic forecast should not automatically become the valuation assumption at each later close.
Set a review point tied to actual sales or stock age. If demand falls behind the approved case, decide whether to change replenishment, pricing or permitted disposition before another minimum order compounds the excess. Update the purchasing defaults when supplier terms change, and preserve the old decision so the eventual stock outcome can improve the next negotiation.
