Marketplace Seller Suite — WB/Ozon prices, SEO, unit economics, supply

5 seller tools for Wildberries and Ozon in one kit: competitor price monitoring, an SEO description generator, full unit economics, review replies and supply tracking. Python 3.9+, no external dependencies — unzip and run.
One JSON catalog — and you have the numbers for your business: profit per unit and per month, the breakeven point, which supplier is falling behind, which products lose money, and what to answer on every review. Written on the Python standard library: no pip install and no cloud subscriptions.

5 MODULES (modules/ folder, run with python run.py )
• price_monitor — competitor prices: parsing WB and Ozon product cards, comparison with your prices by SKU, market statistics (min/max/median, average rating). The price is looked up where the ₽ sign stands — "Mug 350 ml 690 ₽" gives 690, not 350
• seo_descriptions — SEO descriptions: builds a description from the product´s characteristics block by block, scores it for WB and catches the stop words that make the marketplace cut the description ("hit", "sale", "promo code", "hurry up and buy")
• unit_economics — unit economics: commission, logistics, acceptance, storage, non-buyouts, ad spend (DRR), tax, packaging. Breakeven by price and by volume, ±15% scenarios
• review_replies — review replies: 5 review types, a polite answer built from the order data, checked against wording the marketplaces forbid (contacts off-platform, promo codes)
• supply_tracker — supply: how many days of stock is left, the reorder point accounting for lead time and safety stock, an order plan grouped by supplier
NUMBERS FROM THE DEMO (6 products included)
• Revenue 706,620 RUB/month, profit 159,511 RUB/month
• Average margin 22%, the first product´s breakeven is 808 RUB at a 410 RUB cost
• To order: 3 products, 340 units, split across 3 suppliers
VERIFICATION — 196 CHECKS
python selftest.py recalculates every formula independently of the modules, stress-tests the parser on edge cases, and checks the review replies against forbidden wording. The gallery screenshots are real module output on the demo data, not drawn mockups.
FOR WHOM
• A WB/Ozon seller — see what every product really earns and stop selling at a loss
• A beginner — understand the commission and every cost before entering the marketplace
• Anyone launching a new SKU — learn the minimum price at which you still break even
BEFORE REAL CALCULATIONS
The default tariffs (19% commission, 65 RUB logistics, 35 RUB acceptance, 12 RUB/month storage, 10% non-buyout, 7% ads, 6% tax) are at the top of unit_economics.py — compare them with your own tariff and change them in one line.
