Case study
Fashion apparel and accessories brand
Sales up 249% and net profit up 205% year over year, with spend scaled 4x.
A fashion apparel and accessories brand grew sales 249% and net profit 205% year over year while media investment scaled 4x. It finished the period at a 41% net margin with MER at 29%, meaning paid media absorbed 29 cents of every revenue dollar. Rising acquisition cost was tracked and managed as a known trade rather than discovered as a surprise.

The setup
A fashion apparel and accessories brand in aggressive growth mode: media investment scaling 4x, and with it the classic risk that top-line growth quietly outruns profitability.
The risk in a scale-up of that size is specific. Acquisition cost rises as spend climbs, and the revenue chart keeps looking good long after margin has started to slip. Ownership wanted the growth, and wanted to see profitability in real time while it happened.
What we ran
The growth push, instrumented properly. New customer CPA and new customer ROAS were tracked as spend scaled, so rising CAC was a known, managed tradeoff rather than a surprise. Blended sales and margin reporting gave ownership continuous visibility into true profitability, not just the revenue chart.
Three measurement choices carried the scale-up.
- New customers separated from returning customers. Acquisition was judged on what a first-time buyer actually cost, not on revenue from customers the brand already had.
- MER as the top-line check. It covers every channel at once and cannot be gamed by an attribution window.
- Margin reported next to revenue. The decision to keep scaling was made against profit, not against the size of the sales chart.
The result
Total sales up 249% and net profit up 205% year over year. Growth that showed up on the bottom line, not just the dashboard.
Net profit grew almost as fast as sales through a 4x increase in media investment, and the business finished the period at a 41% net margin with paid media at 29% of revenue.
How the numbers were measured
MER is expressed here as paid media spend as a share of revenue, so 29% means 29 cents of every revenue dollar went to media. New customer CPA is acquisition spend divided by first-time buyers, and new customer ROAS is first-time buyer revenue divided by acquisition spend. Both are what separate genuine acquisition performance from repeat purchase revenue.

Why it matters
A 4x spend scale-up usually ends one of two ways: with a bigger business, or with a bigger burn rate. The difference is whether anyone is watching new customer economics while it happens.
Most brands find out which one they got a quarter later. Tracking new customer economics as spend climbs means finding out while there is still time to adjust the pace.
