What is the Commercial Decision Layer?

The Commercial Decision Layer is the layer of human judgement that sits between an ecommerce ad platform and the company P&L. It translates Google Ads signals into commercial decisions by applying contribution margin, SKU role, cash position and growth mode - context the platform's bidding cannot see.

Why does the Commercial Decision Layer exist?

Google's automation optimises platform metrics (ROAS, conversion volume, conversion value). It cannot see margin variance across SKUs, returns rates by category, fulfilment cost, payment processing, promotional discount or the brand's cash position. Without a decision layer above the platform, automation reliably grows revenue while eroding profit.

Who created the Commercial Decision Layer framework?

The Commercial Decision Layer was developed by Chris Avery, Co-founder of JudeLuxe, the UK ecommerce Google Ads agency. It is the operating model JudeLuxe runs for every retained client.

How is the Commercial Decision Layer different from a regular agency service?

Most agency services are platform-management services: they implement Google's recommendations and report what the platform reports. The Commercial Decision Layer is platform-independent: it makes commercial decisions first, then translates them into platform actions. The agency role becomes accountability to the P&L, not to the dashboard.

What are the five components of the Commercial Decision Layer?

Margin truth (per-SKU contribution margin maintained monthly), SKU role classification (Scale, Profit, Protect, Recovery, Gateway), POAS bidding (profit values fed to Google), margin-aware budget pacing (daily decisions on POAS not ROAS), and CFO-aligned reporting (monthly P&L mapping).

Definition

The Commercial Decision Layer is the layer of human judgement that translates ad platform signals into commercial decisions, applying margin context, SKU role, cash position and growth mode that automated bidding cannot see.

Why it exists

Google's bidding stack is the most sophisticated value-chasing engine in commercial use. It optimises whatever value signal it is fed, ruthlessly, at scale. The problem is not the engine. The problem is the signal.

By default, Google is fed revenue. It cannot see contribution margin across a 50-percentage-point SKU spread. It cannot see returns rates that hollow out apparel campaigns. It cannot see fulfilment cost, payment processing, promotional discount, or the cash position of the business it serves. So it does what it was built to do: it grows the metric in front of it.

The Commercial Decision Layer is the corrective. It sits above the platform, applies commercial context, and translates that context into the signals the platform consumes. The result is automation pointed at profit, not revenue.

The five components

Margin truth

Per-SKU contribution margin (CM3) maintained monthly. The precondition for everything else. Without it, every downstream decision is guesswork.

SKU role classification

Every SKU classified into one of five jobs: Scale, Profit, Protect, Recovery, Gateway. The framework that turns an undifferentiated catalogue into a portfolio with intent.

POAS bidding

Profit values fed to Google's bidding stack. ROAS is replaced by POAS (Profit on Ad Spend). Targets calibrated to commercial mode, not industry average.

Margin-aware budget pacing

Daily and weekly budget decisions made on POAS performance, not platform ROAS. Spend follows contribution, not conversion.

CFO-aligned reporting

Monthly reporting that maps ad spend to P&L impact. The platform dashboard becomes a working artefact, not a deliverable. The public template is our CFO Board Pack.

Provenance

The Commercial Decision Layer was developed by Chris Avery, Co-founder of JudeLuxe, and operationalised by Gee Kullar, Co-founder, who owns the agency's delivery and reporting standards. The framework has been the operating model behind 75+ retained ecommerce accounts since 2021.
