Give out-of-stock visitors an honest choice
Separate waiting, substitution and discontinuation so customers know what happens next.

An unavailable item does not create permission to substitute a different one or promise a restock. A good stockout experience explains the current state and offers only next steps the business can support.
What you will leave with: Design distinct paths for temporary stockouts, unknown replenishment and discontinued products.
Use this when
- Campaign traffic reaches unavailable products.
- Customers join availability lists but receive confusing follow-ups.
This is not an inventory forecasting model or permission to convert a stock alert into ongoing promotional consent.
Name the actual inventory state
Start with operations, not the empty-state headline. Is the product temporarily unavailable with confirmed incoming stock, awaiting an uncertain supplier date, discontinued or purchasable on backorder? Each state carries a different customer commitment. Write the evidence behind the state and identify the person who can update it.
Do not let “coming soon” become a permanent substitute for uncertainty. State that timing is unknown when it is unknown. Keep purchase controls consistent with the actual ordering policy. Google’s availability guidance distinguishes in-stock, out-of-stock, preorder and backorder states; those labels are not interchangeable ways to keep an offer visible.
Offer alternatives by the job they can still perform
A substitute deserves a reason. Explain the feature it shares and the feature it changes: capacity, material, dimensions, price or compatibility. Do not use “similar” to conceal a decisive difference. For replacement parts, uncertain compatibility is a reason to ask a specialist rather than recommend a close-looking item.
Give waiting equal clarity when it is a real option. An availability alert should say what event triggers it and whether it reserves anything. A notification is generally not a reservation unless the business explicitly provides one. Ask only for contact details required for the alert and obtain any separate marketing permission through the appropriate process.
Control what happens when stock returns
Decide whether the alert is sent when goods are ordered, received, inspected or actually available for sale. “Back in stock” should correspond to a purchasable state, not a supplier’s optimistic promise. If available quantities are small, avoid sending an unrestricted invitation to a much larger list without explaining allocation.
Have a plan for people who open the message after stock sells out again. The link should lead to the current state and make rejoining or leaving the alert clear. Do not invent urgency with a countdown unrelated to inventory. Keep discontinued-item alerts from lingering indefinitely by closing them with an accurate explanation when necessary.
Coordinate discovery, messaging and operations
Check collection pages, search suggestions, product pages, ads and saved cart messages. Shopify documents options to display, hide or place unavailable search results last. The right choice depends on whether people need product information or only purchasable items. A discontinued support page may remain useful even when the item is not merchandised as available.
Review alert accuracy, time between stock change and notification, unsuitable substitutions and complaints about implied reservations. Do not label every purchase after an alert incremental revenue. Some buyers would have returned anyway. The immediate quality test is whether each customer received a true statement and an actionable path.
Make the reasoning concrete.
A fictional outdoor store has sold out of a compact camping chair. A shipment is confirmed but has not arrived. A heavier chair is available now, and a discontinued color will not return.
Wait for the compact model
Opening: Offer a one-time availability alert with no reservation promise.
Hypothesis: Customers with a weight constraint can wait for a suitable item.
Risk: The alert must not go out before saleable stock exists.
Choose an available alternative
Opening: Show the heavier chair with its additional weight clearly stated.
Hypothesis: Customers who value immediate availability can make an informed tradeoff.
Risk: A superficially similar product may fail the original use case.
Keep the discontinued color separate from temporary shortages. Trigger the compact-chair alert only after stock is ready to sell.

Use these prompts in your own notes. Nothing is submitted from this page.
State and evidence
What is unavailable, and what is actually known about its return?
Customer options
Can the person wait, choose a verified substitute or get an answer?
Alert promise
What triggers the message, and does it reserve stock?
Late arrival
What does someone see after the item sells out again?
Ownership
Who updates the page, feed and alert when the state changes?
Watch for the wrong conclusion.
- Calling an unconfirmed supplier date a customer promise.
- Treating stock alerts as permission for a general newsletter.
- Hiding important differences in recommended substitutes.
Your next action
Choose one unavailable product and map its customer experience for temporary, uncertain and discontinued states.
