A practical workflow
Follow the guide step by step
- 01
Confirm the inputs first
Check marketplace, category, listing price, product weight or size, fulfillment method, supplier pack, and the costs you entered. Correct weak or missing inputs before relying on the results.
- 02
Read profit, margin, and ROI as different measures
Estimated profit is the amount left per unit under the model. Margin compares that result with selling revenue; ROI compares it with the invested cost basis.
- 03
Use break-even and maximum buy price for different decisions
Break-even estimates a selling-price threshold. Maximum buy price works backward from the target return you choose to estimate a supplier-cost ceiling.
- 04
Check confidence, status, and diagnostic reasons
The fee estimate confidence indicator reflects the quality of available fee inputs, not certainty about demand or future profit. PASS, WARNING, or REJECT and the Buy, Review, or Avoid recommendation follow your configured thresholds and product checks.
- 05
Verify non-math buying gates
Confirm the exact variation and pack, marketplace eligibility, hazmat status, and IP or authenticity concerns. A seller-entered risk check is not marketplace approval or legal advice.
The calculation is only as complete as its assumptions
The audit can include supplier cost, shipping, fulfillment, category referral assumptions, storage over an expected hold period, inbound or placement costs, return processing, returns allowance, discount, and advertising. Add the relevant costs and use current marketplace references to verify fee assumptions.
A saved fee schedule can help reuse your own named assumptions. It is a planning profile, not an official fee schedule or a live quote from Amazon or Walmart.
Treat a verdict as a screening signal
Decision thresholds such as minimum profit, minimum ROI, and a thin-margin warning can be adjusted for your buying rules. Separate product math from demand, competition, listing eligibility, supplier quality, and cash availability.
If the result is near a threshold, test a lower price or another supplier cost, inspect the reason list, and verify the information that would change your decision.
Read results in order
Start with any data warnings, then read profit and ROI, then the downside scenarios. A good profit with an open data warning is still a Review.
Finish with the maximum buy price, which tells you the most you can pay and still meet your threshold.
Three results that call for different next steps
Positive estimated profit with low fee confidence is a measurement problem: verify category, dimensions, weight, and fulfillment classification before relying on the number. A Buy signal with MOQ cash above your budget is a capital constraint: reduce the order only if the supplier terms allow it, or pass on the opportunity.
A result that changes from Buy to Review after a small price reduction has little modeled cushion. Recheck the assumed selling price and supplier quote, then compare the lower-price case with your own minimum return threshold.
- Resolve low-confidence inputs before judging the profit result.
- Review order cash and pack mapping even when the per-unit result is positive.
- Use diagnostic reasons to decide what to verify first; thresholds do not predict demand.
Common questions
Frequently asked questions
Does high fee confidence mean the product is safe to buy?
No. It describes confidence in fee inputs, not demand, eligibility, supplier quality, listing stability, or realized profit.
What makes an audit show Review or Avoid?
The outcome follows the current assumptions, configured thresholds, and checks such as pack matching and seller-confirmed restrictions. Read the diagnostic reasons and verify the underlying details.
Is maximum buy price the amount I should offer?
It is an estimated supplier-price ceiling under the inputs and target ROI you selected, not a purchase instruction. Confirm the pack, MOQ, demand, and risks before placing an order.
What does Review mean in the audit?
It means an input needs checking before the result is reliable, such as a missing weight or an unverified pack match.
