Out of stock complaints in retail reviews

Why they matter

Out of stock complaints are lost sales written down. A customer who came for a size, did not find it and wrote a review is telling you exactly what demand you missed, and where.

What to tag

• Product or range mentioned.
• Size or variant.
• Whether they saw it online first.
• Whether staff offered alternatives or ordering.
• Store and date.

Patterns to look for

• Specific sizes missing across many stores: size curves.
• Specific stores missing many items: replenishment or space.
• Items seen online but not in store: availability information.
• Complaints after promotions: demand forecasting.

Routing

• Size curves and allocation: merchandising.
• Replenishment frequency: supply chain.
• Online availability accuracy: e-commerce.
• Offering alternatives and ordering: store training.

An example

A footwear chain finds out-of-stock complaints concentrated on two sizes in one popular range, across most stores, after a reallocation. Merchandising adjusts the size curve; complaints for that range fall within a season.

What store teams can do

Offer an alternative, check another store, or order for delivery. Reviews often say whether staff did; that is a training signal in itself.

Common mistakes

• Treating stock complaints as store failures.
• Not tagging size and product.
• Ignoring online-to-store gaps.
• No link to replenishment data.

Common questions

Checklist

• Product, size and store tagged.
• Patterns checked across stores.
• Routed to the right owner.
• Linked to replenishment data.

In short

Tag what was missing and where, look for size, store and online-to-store patterns, and route them to merchandising and supply chain as well as store teams.

Measuring and reporting

Report out-of-stock complaints as a share of reviews per store and month, and separately by product range and size where customers mention them. Put the count beside every number. Compare with in-stock data for the same stores and weeks. When both agree, the cause is usually allocation or replenishment; when only reviews show a problem, check shelf availability and online stock accuracy.

Online-to-store gaps

Many complaints start online: "the website said it was in stock". These point to how store availability is shown online. Count them separately; they are often cheaper to fix than the stock itself, by improving the accuracy or freshness of availability information.

Seasonal and launch peaks

Stock complaints often spike after promotions, at festive peaks and after popular launches. Compare those periods with the same period last year and feed the findings into the next season's allocation plans.

Replying to stock complaints

Thank the customer, say what you can do, such as ordering the size or checking another store, and give a contact. Replies that offer a practical route often turn a lost sale into a later one.

Doing this with Falcon

Falcon shows negative share by topic, location and month on one heatmap, flags locations with too few reviews to compare, and lets you compare any period with the one before or the same weeks last year, so a location's problem can be told apart from a network-wide one. Every number opens the reviews behind it, in customers' own words, so a comparison can always be checked.
