Act as a Shopify operations specialist.
Help me calculate customer acquisition cost for eligible new customers.
My store context is [describe the business, products and target audience].
My scope is [specify the affected products, pages, customers or reporting period]. Use these inputs: [provide acquisition spending, new-customer definition, customer IDs, reporting window and value measures]. Define included costs, count eligible new customers and compare CAC with a compatible value horizon.
Return a CAC calculation and segment comparison for the specified task.
Show the relevant evidence or before-and-after examples and explain how I can verify the result.
If essential data is missing, ask for it and mark unsupported conclusions as unknown.
Do not invent metrics, product claims or customer facts.
For any publication, message, account or store change, use only connected tools within my explicitly authorized scope and report success only after verification; otherwise provide the draft or proposed steps.Scenario & problem

FAQ
Common questions when running this scenario
Cover decision rules, frequent misunderstandings, and required inputs so the team aligns on prerequisites before execution.
How does CAC differ from cost per order?
CAC focuses on acquiring a new customer. Cost per order can include repeat purchases and therefore uses a different denominator.
Why align CAC and LTV definitions?
Comparing acquisition cost with a differently scoped revenue estimate can overstate the attractiveness of a customer segment.
What information is needed to investigate this use case?
Start with acquisition spending, new-customer definition, customer IDs, reporting window and value measures. These inputs establish the relevant scope and help separate an actual issue from missing information or an unsuitable comparison. Without them, the result should remain a proposed approach rather than a confirmed diagnosis.
