For sellers
USN tax from Wildberries reports
The extension reads weekly detailed report files from the open Wildberries seller reports page and calculates totals by sale date, including boundary weeks split across quarters.
Income minus expenses
Reads supported Wildberries fees and service costs from report rows, then combines them with manually entered non-WB expenses by quarter.
Quarter breakdown
Shows income, expenses, base and tax for each quarter, while hiding empty quarters at the edges of the found period.
Workflow
Designed for Wildberries reports
Open the Wildberries reports page
The extension detects the open Wildberries financial reports tab and uses the current seller account as the cache boundary.
Download only what is missing
Verified report files remain in the local cache. The next calculation downloads missing reports and reuses existing files where possible.
Export a diagnostic log
If the Wildberries report structure changes, the extension shows a friendly warning and lets the user export a log for review.
Local-first data
Report files, parsed rows, cache and calculation results are processed locally in Chrome by default.
Accounting caution
The tool is a calculation aid. Final tax payments should be checked against KUDiR, source documents and current tax rules.
