// Ecommerce · the ROAS engine

We scale ecommerce on profit, not vanity ROAS.

Profitable, repeatable revenue, built on contribution margin and blended ROAS, with the creative velocity and clean tracking that modern ecommerce demands.

// The problem

Platform ROAS flatters. Profit tells the truth.

Meta and Google each report the conversions they can claim, so they double count each other and over credit themselves. Scaling on that number quietly burns margin. We manage to the numbers your accountant recognises.

// The system

The DUMASS ecommerce engine

Account structure

Advantage Plus and Performance Max for scale, with manual campaigns where control and margin matter. The right mix for your catalogue and stage.

Creative velocity

A testing engine, not one off ads. A steady flow of angles, hooks and formats so the algorithm always has fresh winners to scale.

Full funnel coverage

Prospecting to bring new buyers in, retargeting to convert intent, and retention to grow repeat revenue and lifetime value.

Feed and catalogue

Clean titles, attributes and imagery so Shopping and Advantage Plus catalogue ads work hard for every product.

Server side tracking

Conversions API and server side events to recover the signal lost to iOS and cookie limits, so optimisation stays accurate.

Profit reporting

One dashboard that ties spend to blended ROAS, MER and contribution margin, in language you can act on.
