## The business

A fashion retailer ran a healthy multichannel business, judging its online and store channels on their reported margins. Online carried the high return rates typical of apparel, but the cost of processing those returns, logistics, inspection, refurbishment and write offs, sat in a central operations line rather than being attributed back to the channel that generated it.

## What triggered the audit

Online looked comparably profitable to stores on the reported channel margins, which felt wrong given its return rate. The audit rebuilt channel economics with full returns processing cost attributed to the channel that generated each return, testing whether online’s reported margin survived once its own returns were charged to it.

## What the audit found

Online’s reported margin was flattering because it wasn’t carrying its own returns cost. Apparel returns are expensive, reverse logistics, inspection, repackaging, markdowns on returned stock and outright write offs, and online generated the overwhelming majority of them, yet all of that cost was pooled centrally and never attributed back to the online channel. So decisions about where to invest and how to price were being made on a channel margin that simply omitted one of online’s largest real costs. Because the returns cost was centralised and invisible at channel level, online looked healthier than it was and continued to attract investment on false economics. Properly attributed, unallocated returns cost was distorting the picture by roughly $69k a year.

◉
How we produced this finding

To surface the returns economics finding, MarginFix reconstructed the true cost of each unit and order, loading in every fee, return and hidden charge the retail headline numbers ignored. The resulting contribution margin read was checked against the client’s own cost data and approved by a named senior auditor.

Data sources: Cost of goods, returns economics inputs, fulfillment, fees, returns and discounts, reconciled per unit and per order, so the true contribution margin behind every single sale is visible rather than assumed.

Key frameworks: A full contribution margin and cost to serve rebuild, full cost ROAS and margin based ROI analysis, framed by the Enterprise Marketing ROI Framework that treats spend as a capital allocation decision.

Human validation gate: Every number is rebuilt on your own cost data and signed off by a named senior auditor before it ships. No figure leaves the building without a human standing behind it.

Working paper: online margin once its returns are charged in traced line by line and reconciled to invoiced margin in the P&L over a matched period. Line items representative and redacted; the recovered figure is the reconciled audit finding.

## What we changed

✓

Attributed the full returns processing cost, reverse logistics, inspection, refurbishment and write offs, back to the channel that generated each return.

✓

Rebuilt each channel’s P&L on true, returns loaded margin, so investment and pricing decisions finally rest on real economics rather than a flattering figure.

✓

Targeted the highest return categories and SKUs with sizing, fit and description fixes to reduce the returns driving the cost at its source.

✓

Made returns cost a monitored channel level metric, so it can no longer hide inside a central operations line and distort the picture.

## The result

The published chart shows online channel margin at 2% after returns processing costs were allocated to the channel. The annual figure is a cost reallocation that corrects channel economics, not a claim that the same amount was removed from cash spending. $69k a year of distortion corrected by charging returns cost to the channel that creates it, an annual figure equal to 12× the $5,950 Audit + Sprint fee. For any multichannel retailer, the pooling is the trap: centralised returns cost makes online look more profitable than it is, steering investment on false margins. If your channel P&Ls don’t carry their own returns cost, you may be scaling the wrong channel. It takes attributing returns to source to see it. A fixed fee audit does that in days, before more budget follows the flattering number.

From kickoff to signed off findings: 7 days.
