Why does profit differ on the Dashboard and in Product Economics?

A common question arises: why do the expense and profit figures in summary reports (Financial Reports, Dashboard) differ from those in product-specific reports (ABC Analysis, Product Economics)?

What is the reason?

The issue is that marketplaces do not provide a breakdown of many expenses by item. For example, paid subscriptions (JAM, Premium), often paid acceptance at Wildberries, and part of Ozon's logistics fees (cross-docking) are given without a breakdown by item.

We do not automatically allocate such expenses. The dashboard accounts for everything. Product Economics may not include some write-offs. We currently do not display them specifically, but you can check the marketplace's own report. For Wildberries, check the weekly report details; for Ozon, check the accrual report — shipment export (not by product!); for Yandex Market, check the service cost report — and find transactions where no item number is specified.

Product Economics is not a breakdown of the dashboard. You should not calculate the total sum from it. This section is intended for comparing a product with itself or with other products.

Where is the most accurate data?

The Dashboard and the Financial Reports section (as well as the P&L) account for everything. They contain the most accurate profit data.

How then to calculate the total profit for a group of products, accounting for everything?

Take the ratio of gross revenue or gross profit for these products (say, it turns out to be 2:1) and apply it to the total net profit (1/3 and 2/3 of the total revenue or profit, respectively).
