Return Reason - Brief Definition
Return reasons, also known as return reason codes, are standardized entries used to record why customers return a purchased item. They allow returns to be systematically categorized and their underlying causes to be analyzed.
While the return rate shows how many items or orders are returned, return reason codes explain why they are sent back.
This metric and data foundation helps companies identify recurring issues with products, sizing, quality, or shipping processes and make targeted improvements.
In short: Return reasons reveal why products are returned and where there is potential for optimization.
Why are return reasons important?
Returns incur additional costs for transport, receiving, quality control, processing, and restocking. However, the sheer number of returns says little about what causes these costs and how they can be reduced.
Only through structured recording of return reasons can companies identify which problems occur most frequently.
This information is particularly important in fashion e-commerce. For example, if a specific garment is returned more often than average due to an improper fit, it may indicate issues with the size chart, the fit itself, or the product description.
If, on the other hand, incorrect items are delivered regularly, the cause may lie in order picking or item labeling in the warehouse.
Analyzing return reasons therefore supports not only return management, but also product development, purchasing, marketing, customer service, and fulfillment.

What are the reasons for returns?
Reasons for returns should be defined as clearly and consistently as possible. This allows returns to be compared across different products, time periods, and sales channels.
Typical return reason codes in e-commerce include:
- Size: Item is too big or too small.
- Fit: The product does not fit as expected.
- Color or material: The item does not match the representation in the online shop.
- Quality: Workmanship or material do not meet expectations.
- Damage: The product was delivered damaged.
- Wrong item: A different product or the wrong variant was delivered.
- Late delivery: The order was not delivered on time.
- Did not like: The item does not match personal taste.
- Selection order: Multiple sizes or variants were ordered and partially returned.
- Defective: The product has a technical or functional defect.
Depending on the product range, other categories may be useful. For fashion brands, for example, differentiated information on size, cut, and fit is particularly helpful.
It is important that the categories are easy to understand and have as little overlap as possible.
How are return reasons recorded and measured?
Return reason codes are typically captured during the registration or processing of a return. Customers select a reason for the return from a predefined list.
Alternatively, return reasons can be documented by customer service or during the return processing stage.
The following data is frequently used for analysis:
- Return registrations in the online shop or return portal
- Order and item data from the OMS
- Return receipts and quality inspections in the WMS
- Item numbers, sizes, and variants
- standardized return reason codes
- documented complaints
- data from customer service
The individual return reasons can then be analyzed as a percentage.
Share of a return reason = Returns with this return reason ÷ Returns with a recorded return reason × 100
Example: If 400 items out of 1,000 total returns are sent back due to an incorrect size, the share of this return reason is 40%.
Consistent recording is essential. If customers can choose different terms for the same issue, the results become less meaningful.
Furthermore, not only absolute return figures but also the sales figures for the respective products should be taken into account.
Typical mistakes when recording return reasons
Unstructured recording can lead to the loss of important information or result in incorrect conclusions.
Common mistakes include:
- too many confusing return categories
- unclear or overlapping labels
- frequent selection of "Other" without further details
- failure to record individual returns
- inconsistent categories across the shop, OMS, and WMS
- no distinction between product defects and fulfillment errors
- lack of mapping to item numbers and variants
- no regular data analysis
Another problem arises when only customer feedback is taken into account, even though the subsequent quality control check reveals a different situation.
For example, a return might be registered as "delivered damaged," while the actual cause can only be accurately classified during inspection at the warehouse.
Therefore, it can be useful to document the return reason provided by the customer and the result of the internal quality check separately.
How can return reasons be analyzed more effectively?
Systematic analysis should go beyond a simple overview of the most frequent return reasons.
Data becomes particularly insightful when combined with product information, order volume, and operational KPIs.
Key measures include:
- defining standardized return categories
- capturing return reasons directly in the returns portal
- automatically linking data with the OMS and WMS
- return reasons by SKU, evaluate size and variant
- Regularly check for anomalies in individual products
- Compare customer feedback with quality control results
- Distinguish between product-related returns and fulfillment errors
- Report recurring issues to purchasing and product development
- Document changes following optimization measures
The goal is not just to collect as much detailed data as possible. What matters is deriving concrete actions from the information gathered.
Return reasons in fulfillment
In fulfillment, return reason codes help process returns efficiently and identify operational sources of error.
If, for example, the return reason "wrong item delivered" is frequently recorded, an analysis of the picking process may be necessary. Possible causes include unclear warehouse layout, similar item numbers, or missing scanning processes.
For damaged products, however, you should check whether the packaging provides sufficient protection and at what point in the shipping process the damage occurs.
Return reasons are also relevant for the returns processing itself. They can provide clues as to which inspection and refurbishment steps are required for a returned product.
Especially in fashion, beauty and lifestyle , fast and careful processing is crucial so that sellable items can be restocked as quickly as possible. MOODJA specializes in this. Feel free to contact us for a no-obligation consultation.
