The 90-day product profitability audit
One week can be noisy. One year can hide recent deterioration. A rolling 90-day window is often long enough to expose patterns while remaining recent enough to support decisions.
Audit the product, not just the store
Store-level revenue can hide weak products. A bestseller can consume more capital, support and advertising than it returns, while a lower-volume product can create stronger contribution profit.
The audit should therefore begin at product level and only then roll up to portfolio and store-level conclusions.
Review five evidence groups
- Economics: sale price, discounts, product cost, fees, shipping, returns and contribution profit.
- Demand: units sold, sales consistency, channel mix and meaningful changes over the period.
- Acquisition: ad cost per sale, break-even ROAS and whether paid traffic improves or weakens unit economics.
- Offer quality: listing completeness, benefit clarity, trust signals, objections, shipping and returns information.
- Operational risk: stock pressure, fulfillment issues, refunds, support burden and cash tied up in inventory.
Compare periods, not isolated numbers
A margin of 18% means something different if it was 30% ninety days ago. Trend direction matters because deterioration can appear before the product becomes visibly loss-making.
Use consistent definitions between periods. Changing how shipping, returns or ad cost are allocated can create a false trend.
End with a decision category
- Scale: economics and demand are both strong enough to justify controlled expansion.
- Protect: the product is healthy but vulnerable to discounting, ads or cost increases.
- Fix: a specific pricing, cost, listing or acquisition issue has a credible remedy.
- Test: evidence is incomplete and a bounded experiment is cheaper than a premature decision.
- Exit: persistent weak economics do not justify further capital or attention.
Decision takeaway
A useful audit does not end with a score. It ends with a documented decision, the evidence behind it and the condition that would change it.
Educational guidance only. Use your own verified costs, fees, taxes, channel rules and operating data before making material business decisions.
