01 — Overview
Commercial quality of growth
This brand operates separate Australian and US Shopify stores, requiring market-specific trading, acquisition and retention decisions. September 2026 was the first September with ecommerce operations and paid media managed under consolidated leadership.
The objective was not simply to increase traffic or platform-reported revenue. It was to improve the commercial quality of growth: stronger sales, more orders, better returning-customer performance and more disciplined use of paid-media investment.

02 — The challenge
Two markets, one commercial standard
- Two Shopify markets with different levels of maturity and performance.
- Paid-media efficiency needed to improve.
- Ecommerce, acquisition and retention performance needed to be evaluated together.
- Reporting had to distinguish Shopify sales from ad-platform attribution.
- The US market required recovery after a weak September 2025.
- Growth needed to be commercially disciplined rather than driven by higher spend alone.
03 — Scope of ownership
What consolidated leadership covered
- Ecommerce trading and commercial planning
- Shopify AU and US oversight
- Google and Meta performance direction
- Paid-media budget allocation
- Campaign and promotional planning
- Klaviyo lifecycle and campaign marketing
- Conversion and customer-behaviour analysis
- Cross-market performance reporting
- Agency and platform coordination
- Revenue, ROAS, spend and retention analysis
04 — Commercial approach
Four operating pillars
01
One commercial view
Connected Shopify sales, customer, traffic, paid-media and lifecycle performance instead of assessing each channel in isolation.
02
Spend discipline
Evaluated budget against revenue and attributed return, then shifted focus toward the more productive channel and market opportunities.
03
Market-specific decisions
Managed AU and US as separate commercial markets rather than combining AUD and USD or applying one strategy to both.
04
Customer quality
Tracked returning-customer revenue and returning-customer share alongside acquisition results.

10 — Interpretation
What the results show—and what remained to improve
The Australian market recorded the clearest commercial improvement: higher revenue, more orders and stronger returning-customer performance with materially less paid spend.
The US market showed a strong recovery from September 2025, supported by higher AOV and returning-customer revenue. However, it had not yet surpassed September 2024 revenue, and conversion remained below its earlier benchmark. This distinction informed the next phase of conversion and Meta optimisation.
Results compare the same completed September trading days in each market: 1–21 September for Australia and 1–20 September for the United States. Shopify sales, orders, native AOV and sessions were sourced from Shopify reporting. Paid-media spend and attributed return were sourced from Meta, Google and consolidated reporting. September 2026 results are month-to-date and do not represent a completed calendar month. AUD and USD results are reported separately.
