Know the break-even line before the first test
Ask Claude to model the economics of one SKU across selling prices, conversion assumptions, order volumes, and ad costs, with every input visible and editable.
Prepare
Bring the evidence and boundaries
Claude is most useful here when the source material and the stopping rule are explicit.
- Product cost, shipping charge, packaging or handling cost, and any per-order supplier fees
- Payment-processing assumptions, expected refund or reship allowance, taxes or duties you have independently confirmed
- Candidate selling prices, target ad-spend range, target ROAS, and test volumes
Run
Start with a prompt built for this test
Replace the placeholders with your product, store, supplier, creative, or metric context.
Build a margin table for this test SKU using the costs and fee assumptions I provide. Show contribution before ads, break-even CPA, break-even ROAS, and outcomes at three selling prices and three order volumes. Label every assumption.
Review
Check the reasoning before the action
Keep facts, assumptions, production choices, and consequential decisions easy to inspect.
- Builds a landed-cost stack without hiding fees inside a single unexplained number
- Calculates contribution before ads, break-even acquisition cost, break-even ROAS, and price floors
- Shows how the outcome changes across price, ad cost, refund allowance, and volume scenarios
- Marks unverified assumptions and keeps legal, tax, and customs questions outside the calculation
What you get
A useful output, with the limits still visible
A reviewable margin table with the break-even price, acquisition-cost ceiling, target-ROAS scenarios, and fragile assumptions clearly marked.
Ready to run it
Take the next decision out of the guesswork.
Open the prompt in Claude, review the assumptions, and keep store changes or spend behind your approval.
Direct answers
What to know before you run this workflow
What do I need to start know the break-even line before the first test?
Start with product cost, shipping charge, packaging or handling cost, and any per-order supplier fees. Add the remaining context listed in the steps so Claude can distinguish confirmed facts from assumptions.
What should I verify before using this pricing workflow?
Verify the source material, cost or policy assumptions, and any missing fact Claude marks. Treat the output as a structured operating draft. Keep store changes, spend, supplier decisions, and legal or platform-policy judgments behind your own review.
Does Claude make the final decision for me?
No. A reviewable margin table with the break-even price, acquisition-cost ceiling, target-ROAS scenarios, and fragile assumptions clearly marked. You remain responsible for checking the evidence, approving consequential actions, and deciding whether the result fits the store, customer promise, economics, and current platform requirements.
