A fulfillment platform for marketplace sellers: 78,832 orders with no manual re-keying

A portal that connects Wildberries, Ozon, Yandex Market, MoySklad, T-Bank, CDEK and Russian Post. We have been building and supporting it since June 2025.

marketplace orders in 14 months: 78,832
turnover of those orders: ₽97.4M
orders in one day, record set on 19 January 2026: 1,456
from the start of development to the first real orders: 2 months

// Client

A fulfillment platform. Wildberries, Ozon and Yandex Market sellers take suppliers' goods from a shared catalog, and the platform's warehouse picks and ships their orders. The platform also gives sellers their own storefronts with delivery, dropshipping, product card generation, a pricing bot, accounting and marketing services.

The system now has 233 accounts: 172 sellers, 34 suppliers, 19 seller-suppliers and 8 administrators. 166 marketplace stores are connected. The catalog holds 7,886 products from 53 suppliers, with stock tracked across 31 warehouses.

// The task

The platform needed a system where an order from any of the three marketplaces reaches the warehouse on its own and the money is split between seller, supplier and platform automatically. Without it, every operation would have been done by hand in three marketplace accounts, in MoySklad and in the bank.

// What the system does on its own

Operation	How often
Pulls new orders from Wildberries, Ozon and Yandex Market	every morning at 05:30 Moscow time
Checks the seller's balance and charges the order cost	for every order
Builds the marketplace shipment, gets stickers and box QR codes	for every shipment
Creates the customer order and supplier orders in MoySklad	for every shipment
Updates stock on the marketplaces	every hour
Recalculates and uploads prices	every 15–20 minutes
Checks payments in the bank	every 5 minutes
Marks dispatch and closes the shipment	every hour from 16:00 to 04:00
Transfers money to suppliers, partners and the platform, processes refunds	every hour
Creates a CDEK or Russian Post parcel and tracks delivery	for every storefront order

What's still manual: picking and receiving at the warehouse, moderating new products and checking FBO requests.

// The hardest parts

Money between three parties

The seller's payment for a shipment is split between suppliers and the platform through T-Bank's safe deal. By default a deal allowed a single payout, so we moved to deals with multiple payouts: suppliers first, the platform last. A refund is issued only after the payment is verified in the bank, so money is never returned twice.

MoySklad as the source of truth

7.9K products and 339K stock rows across 31 warehouses are synced every day. If MoySklad returns incomplete data, the sync stops instead of wiping the catalog.

Three marketplaces, three rulebooks

Wildberries shipments with boxes, Ozon postings and labels, Yandex Market orders. Every morning orders are grouped into shipments by marketplace warehouse.

Updates with almost no downtime

The new version is built while the old one keeps running. Deployment downtime went from about 27 minutes to 40 seconds.
