On the sale date, the item appeared profitable. The buyer later returned it and a negative adjustment appeared in a different week. Looking only at either week can mislead you.
1. Match the return to its original order, SKU, seller account, marketplace and quantity
Track the item's condition separately from the cash entry.
2. Keep three dates distinct: sale, return initiation, and posting of refunds or deductions
A weekly operations report and a sale-cohort profitability view answer different questions.
3. Reconcile confirmed lines: reversed revenue, refunded commission, reverse logistics, storage, repeat delivery and compensation
An empty field is not evidence of zero cost.
4. Recalculate one SKU
Illustrative example: revenue of ₽1,500 less ₽1,100 in variable costs suggests an initial ₽400 contribution. If the sale is reversed and ₽250 of costs remain non-refundable, the transaction's contribution becomes minus ₽250. Inventory cost treatment depends on whether a resellable product returned to stock. This is not customer data or a universal marketplace formula.
5. Review returns across a comparable period
Look at return frequency and total contribution before changing price, content or assortment.
ProfitVena connects sales, returns, commission, logistics and configured cost to a SKU and period: ProfitVena. Results depend on connected data, freshness and the cost-attribution rule. Wildberries can be connected; verify API availability for other sources individually, or use supported Excel/CSV imports.
