Stock availability: making promises that the warehouse can fulfil

A salesperson sees 200 units in company stock and promises immediate delivery of 100. The required variant has only 40 units in the serving warehouse. The overall total was correct, but it did not answer the actual fulfilment question.

Availability concerns whether the right goods can satisfy a particular requirement at the relevant place and time. It needs more context than a single company-wide quantity.

The dimensions of the requirement

The item and variant identify the product. The unit defines the quantity. The warehouse and bin identify its recorded position. Timing determines whether the goods can reach the customer when promised. Any applicable operational restrictions also need to be understood.

DNA's sales, delivery, transfer, and other inventory-related processes use location and stock checks appropriate to the transaction. A warning or block at one source location should not be interpreted as proof that the company has no stock anywhere.

A practical example

A company has 60 units in Boston and 80 in another warehouse. A customer in Boston needs 100 tomorrow. The company-wide total is 140, but only 60 are currently in the serving warehouse.

The remaining 40 may be obtainable through a transfer if the timing and operational conditions allow it. That is a different promise from immediate local availability. The transfer needs to represent the actual movement rather than simply change the selected source without explanation.

Expected supply and existing stock

A purchase order or production plan represents expected future supply. It is not the same as goods already received and available. Supplier delay or production loss can change when that expectation becomes reality.

Similarly, a customer order represents demand. It should not be ignored when assessing future supply requirements simply because the goods have not yet been delivered. Planning needs to distinguish current physical positions from commitments and expectations.

DNA's shared stock check follows the item's Track Inventory setting when that setting is known. Item type alone is not the rule: a service marked for tracking is checked, while an item explicitly not tracked is excluded. When the flag is unavailable, the reviewed helper falls back to excluding services and checking other item types. Repeated lines drawing the same stock are considered together in base units: two lines requesting eight units each from a bin containing fifteen create a shortage of one. This entry check does not establish a reservation of stock for another future transaction.

Responding to a shortfall

A shortage can lead to partial delivery, transfer, purchasing, production, or a revised customer commitment. The appropriate choice depends on the requirement and the cost of the alternatives.

An unexplained adjustment is not a way to manufacture availability. The business needs evidence of the actual supply or movement. Reliable promises come from connecting the customer's need with the warehouse position and a credible plan for any remaining quantity.
