Check 8 / 12 LOW impact In the full checklist
Dashboard: MER, CAC, new customer %, LTV
What this check is
Marketing efficiency needs three numbers together: total revenue against total spend, the cost of acquiring a customer, and what that customer is worth over time. One dashboard that shows them weekly keeps decisions honest.
How to implement it
Build a single view combining platform spend, store revenue, the share of orders from new customers and a repeat-purchase measure, refreshed on a schedule. Define each metric once and write the definition next to the number.
How to verify it
Reconcile one week of the dashboard against the platform invoices and the store’s order report: spend, revenue and new-customer share should match within a known tolerance.
