A stockout happens when an item has no available inventory to meet demand. For a distributor, it means a customer has ordered something the warehouse cannot ship.
A stockout is an inventory event. It describes the position of your stock, not what you then do about the customer’s order. What happens next, whether the line is substituted, held as a backorder or cancelled, is a separate decision.
What causes stockouts
Demand spikes. Weather, local events or a competitor’s closure can lift orders beyond forecast.
Supplier delays. Late inbound deliveries leave gaps that ripple into customer orders.
Forecasting gaps. Seasonal or promotional demand that was underestimated.
Inventory inaccuracy. The system shows stock that is not physically there, so the stockout is discovered during picking rather than ordering.
Slow replenishment. Reorder points set too low for current lead times.
Allocation problems. Stock committed to one large order leaves nothing for smaller accounts.
Types of stockout
| Type | What it looks like |
|---|---|
| Full stockout | No units available at all |
| Partial stockout | Some units available, less than ordered |
| Phantom stockout | System shows stock, shelf is empty |
| Location stockout | Stock exists, but at the wrong depot |
| Temporary stockout | Replenishment already inbound |
Phantom stockouts are the most disruptive because they are found late, often after the order has been confirmed to the customer.
What stockouts cost
For the distributor, the obvious cost is the lost line. The less obvious costs are larger:
- The rest of the order. A buyer who cannot get one item may move the whole order elsewhere.
- Order desk time. Each stockout turns a clean order into an exception that needs a conversation.
- Delivery disruption. Short shipments and redeliveries carry their own cost.
- Account risk. Repeated stockouts give a competitor an opening with that customer.
For the retailer, a stockout is empty shelf space and a shopper who buys the product somewhere else.
Reducing the impact of stockouts
Some stockouts are unavoidable. The difference between distributors is how quickly they are detected and how well they are handled.
Check availability at order capture. Catching a stockout while the buyer is still ordering preserves every option. Checking it at picking removes most of them. This guide to automated order validation in wholesale covers how availability checks fit alongside pricing and catalog checks.
Keep inventory data accurate. Cycle counting and real-time stock updates reduce phantom stockouts.
Prepare substitutes in advance. Agreeing acceptable alternatives with regular accounts turns a decision into a rule.
Tell the customer early. A buyer told at order time can adjust. A buyer told at delivery cannot.
Track stockout patterns. Recurring stockouts on the same SKUs usually point at reorder points rather than bad luck.
Stockout metrics
- Stockout rate: share of order lines with no stock available
- Fill rate: share of demand met from available stock
- Lost line value: revenue on lines that could not be supplied
- Substitution acceptance rate: how often an offered alternative is taken
- Phantom stockout rate: stockouts found at picking rather than ordering
How Ordana helps
Ordana catches stockouts at the earliest possible point, when the order is first read. The Ordana Desk Agent validates every line against live inventory rather than a cached stock figure, so an unavailable item is identified before the order is confirmed.
It then protects the sale rather than just reporting the problem. The agent selects a comparable alternative from your catalog, taking pack size and pricing into account, contacts the retailer with the suggestion and closes the order once they approve. Ordana’s own example shows this loop, from detecting an out-of-stock olive oil to a confirmed substitute order, taking nine minutes with no rep involved.

Frequently asked questions
What is the difference between a stockout and a backorder?
A stockout is the inventory position. A backorder is one way of handling the customer order it affects.
What is an acceptable stockout rate?
It varies by category and supply chain, but the measure that matters commercially is how many affected lines you save through substitution.
How do you prevent phantom stockouts?
Through accurate inventory records, regular cycle counts and validating orders against live stock data.
Does a stockout always lose the sale?
No. A quick, well-chosen substitute often keeps the line and the customer.
