title: Knowing if your ecommerce brand is winning — CTC's three pillars (source of truth, shared target, execution)
slug: ecommerce-growth-three-pillars
summary: Luke Austin's operating framework for ecommerce growth — one trusted source of truth joining financial, marketing, order and calendar data; one shared definition of success (contribution margin at the top, daily targets laddering down to every channel); and relentless execution through calendar, ad, email and creative workflows plus MMM/geo-holdout testing — built in that order.

# Knowing if your ecommerce brand is winning: three pillars

## TL;DR
- **"How's the business going?"** has no answer unless three things are in place, in this order:
  1. **One reliable source of truth.** Financial, marketing, order-level and qualitative (marketing calendar) data in one system, plus an agreed methodology for how you run each channel.
  2. **One shared definition of success.** **Contribution margin** at the top, with daily targets for every metric that ladders down to it (revenue, returning-customer cohorts, each channel). Finance, marketing and the CEO all look at the same dashboard.
  3. **Relentless execution.** Defined workflows for the marketing calendar, ad plan, email plan and creative "ad log", plus MMM and geo-holdout incrementality tests. Adjust within 1–2 days when something under-delivers.
- Brands usually skip straight to step 3. Without 1 and 2 you can't tell good outcomes from bad.
- **Forecasts are always wrong.** The job is to notice the gap early and add new actions to close it.

## Details
Luke Austin (CTC) built this from a fishing trip. A well-equipped boat, agreement on which fish to target, and tight technique all had to be true for a good day. On the day with a worse boat they caught the least.[^1][^2]

**Pillar 1: source of truth and methodology.** All four data types have to live together. With only one to three of them, good decisions are "near impossible", like having sonar but no GPS.[^3][^4] It's hard: a well-known brand Luke spoke to had spent heavily on a tool to unify its data and failed.[^4] CTC's answer is its Statlas tool plus a written methodology (the "CTC Canon") for Meta, Google, creative strategy, forecasting and measurement.[^4][^5]

**Pillar 2: shared definition of success.** Everyone agrees on the data and looks in one place. Otherwise, at month's end, marketing says "we did great" based on platform reports while finance's daily P&L says otherwise.[^5][^6] CTC's home dashboard puts contribution margin at the top, with daily targets for each metric that ladder down. It ties part of CTC's fee to hitting the CM target.[^6] Trade-offs, such as a bit more revenue for a bit less CM, are agreed explicitly.[^6]

**Pillar 3: relentless execution.** Run clearly defined workflows for:[^6][^7]
- the marketing calendar
- the ad plan
- the email plan
- an ad log for publishing high creative volume to Meta
- MMM and geo-holdout incrementality tests

If an email or campaign misses its expected revenue, slot new pieces into the plan within one or two days.[^7] Host Richard Gaffin notes each pillar depends on the one before.[^8] The commitment CTC asks of clients: get the data accurate, lock a target each month, quarter and year, then all work to make the forecast real. Being off plan is expected, and the response is new actions.[^9][^10]

## Disagreements / caveats
- This is a framework talk and pitch, with no outcome data. Statlas and the Canon are CTC products. The principle (one CM-based target and daily pacing) is tool-agnostic.
- Contribution margin needs agreed cost allocations (COGS, shipping, discounts, returns). Agree those definitions in pillar 2 or the dashboard will be disputed.
