Selling & Business Models
What should an online store do when a product sells out?
The short answer
Keep the product page live when the item will return, say plainly that it is unavailable, offer a realistic restock notice, and guide the shopper to a genuine alternative. Remove or redirect the page only when the product is permanently discontinued and you have a close replacement.
First decide what “sold out” means
- Temporary stockout: more units are ordered or can be produced.
- Unknown return date: supply is uncertain.
- Seasonal pause: the item returns in a known period.
- Permanent discontinuation: the item will not return.
- Variant stockout: only certain sizes, colors, or locations are empty.
The message and page treatment should match the situation. Do not display “back soon” when no purchase order exists.
For a temporary stockout
Keep photos, specifications, reviews, and helpful content visible. Disable purchase unless you can honestly fulfill a backorder. State the expected window with appropriate uncertainty, and provide an email or text restock alert with clear marketing consent choices.
Show two or three alternatives only when they solve the same need. Explain the difference: “This version is slightly smaller and ships now” is more helpful than a generic product carousel.
For a variant stockout
Disable only the unavailable combinations. Check that the storefront does not let a buyer choose a sold-out size through a stale quick-add or marketplace feed. If another location can fulfill it, verify routing and delivery before keeping it available. Shopify's multi-location inventory guide explains that stock is tracked separately by location and fulfillment depends on routing configuration.
For a permanent discontinuation
Keep the page if it still serves existing customers with instructions, parts, or care information. Add a clear discontinued notice and link to the closest current option. If the old page has no continuing value, redirect it to a truly relevant replacement or category. Google's redirect guidance recommends permanent server-side redirects when a URL has permanently moved. Do not send every discontinued product to the home page.
Fix the operating cause
Record the stockout date, lost or waitlisted demand, supplier lead time, reorder date, forecast error, and margin impact. Ask whether the cause was stronger demand, delayed receiving, inaccurate stock, cash limits, or a deliberate low-risk test.
Calculate the reorder point:
Reorder point = expected demand during lead time + safety stock
If you sell 4 units per day, replenishment takes 15 days, and safety stock is 20 units, the illustrative reorder point is 80 units: 4 times 15, plus 20. Adjust for seasonality and supplier reliability.
Amazon's inventory-management guide notes that too little stock can disappoint customers while too much ties up cash and creates carrying costs. The goal is not “never sell out.” It is a deliberate balance with a kind customer experience.
