While you are doing ten orders a day, the marketplace seller account and a spreadsheet cover everything. Trouble starts with the second warehouse, the second marketplace and the first hundred SKUs: stock levels drift apart, prices live a life of their own, and FBS orders get picked late. The fix is integration with an accounting system — 1C, MoySklad or another one.
What integration gives you
Integration is an automatic data exchange between your accounting system and your marketplace seller accounts. Four flows get synchronized:
- Stock levels. The accounting system pushes current availability to the marketplaces: sell a unit from the warehouse or on another platform, and the stock figure updates on every storefront.
- Prices. You change a price in one place and it spreads across the marketplaces — no manual edits in each seller account.
- Orders. FBS orders land in the accounting system: picking, labels and statuses are all handled from a single window.
- SKU catalog and documents. Cards, article numbers and barcodes are matched between the system and the marketplaces; marketplace reports are reconciled against your books.
Ways to integrate
Built-in modules. 1C and MoySklad ship with integrations for Wildberries, Ozon and Yandex Market: they install out of the box and cover the basic scenarios — stock levels, prices, orders.
Connectors and middleware services. A separate class of services that link an accounting system to several marketplaces and add logic on top: price rounding rules, reserves, stock allocation across warehouses.
Your own integration via API. Every marketplace has a seller API. Custom code makes sense when the logic is non-standard — for example, when stock is split between FBS warehouses by your own rules. This is the most flexible path and the most expensive one to maintain.
When integration is a must, and when it is too early
Signs that it is time: you work on FBS and have canceled an order at least once because “it sold but there was no stock”; you trade on two or more marketplaces; your assortment has passed several dozen SKUs; prices change more often than once a week. Cancellations caused by stale stock levels hit more than your money — they hit your seller rating too; more on that in the guide on how to work with FBS.
Too early — when you have one marketplace, one FBO scheme and a stable, short assortment: there an honest spreadsheet and manual inventory accounting still cope.
Typical rollout mistakes
- Stock levels update with a long delay. The exchange interval is set to once a day — and in that window the item gets bought on two marketplaces at once. The exchange frequency has to match your sales velocity.
- Duplicated SKU records. The same product is registered under different article numbers in the system and on the marketplaces — the matching breaks and stock figures go astray. Before integrating, bring the SKU catalog into a single reference list.
- Prices overwrite promo prices. The integration pushes the base price over the promotional one and the item drops out of the promo. Price exchange rules must account for marketplace promos, and if you use automatic repricing, cross-check it against the integration so that two robots do not argue with each other (see the guide on repricers).
- Nobody reconciles the reports. Integration is no reason to forget about reconciliation: marketplace reports still have to be matched against your books, as described in the guide on reconciliation with the marketplace.
Rollout checklist
- Bring the SKU catalog into a single reference list: article numbers, barcodes, sizes.
- Choose the method: built-in module → connector → your own API solution, as the tasks get more complex.
- Set the stock exchange frequency to match your sales velocity.
- Test the exchange on a pilot group of SKUs before switching it on for the whole catalog.
- For the first week, check stock levels and prices manually — catch discrepancies while they are still cheap.
Integration is not about a fashionable stack; it is about keeping stock levels, prices and orders in one place so they no longer need manual routine. The sooner the SKU catalog is in order, the cheaper it is to connect any marketplace.
