Backorder vs out of stock
| Backorder | Out of stock | |
|---|---|---|
| Can you buy it now? | Yes, the order is accepted and queued | Usually no, purchase is blocked |
| Will it ship? | Yes, when inventory arrives | Only if and when it is restocked and you reorder |
| Customer expectation | A delay with an estimated ship date | No commitment at all |
Why backorders happen
- Demand spikes: a promotion, press hit, or viral moment sells more than forecast.
- Supplier or production delays: raw materials or manufacturing run behind.
- Inaccurate inventory counts: the system says units exist that are not actually on the shelf.
- Long replenishment lead times: overseas manufacturing and freight leave a gap between stockout and restock.
- Safety stock set too low: no buffer to absorb normal variation in demand.
Are backorders good or bad?
Both, depending on how they are handled. A backorder captures revenue that a plain "out of stock" label would lose, and it signals demand. But long or poorly communicated backorders erode trust, increase support tickets, and push customers to competitors. The goal is to make them rare and, when they happen, to communicate clearly.
How to handle backorders well
- Show backorder status and an estimated ship date on the product page.
- Confirm the delay again in the order confirmation email.
- Update customers if the date moves, before they have to ask.
- Ship partial orders when it makes sense, so in-stock items are not held hostage.
- Offer an easy cancel or swap for customers who cannot wait.
How brands reduce backorders
Backorders are usually an inventory visibility problem before they are a supply problem. The playbook:
- Real-time inventory tracking across every sales channel, so counts are trustworthy.
- Reorder points with safety stock, so replenishment starts before the shelf is empty.
- Demand forecasting around seasonality, launches, and promotions.
- Supplier diversification, so one delayed PO does not stop sales.
This is a core reason brands outsource fulfillment: a 3PL like RitePrep keeps live inventory counts with low-stock alerts across DTC, Shopify, and Amazon from one pool, so replenishment is triggered by data instead of surprises. New to the model? Start with what is a 3PL.
