What multi-platform selling costs
A seller on several marketplaces manages the same catalogue in several places, each with its own format, its own rules and its own dashboard. Stock drifts between them, oversells produce penalties, prices get updated in one place and forgotten in another, and orders arrive in three separate queues that someone consolidates by hand each morning. Meanwhile every customer belongs to the platform, so growth means paying commission on the same buyers repeatedly.
What we build for a marketplace seller
First, stock and price synchronisation across platforms from one source, which eliminates oversells and the penalties that follow. Second, one consolidated order queue feeding fulfilment and your accounting system. Third, analytics across platforms: true margin per SKU after commission, logistics and returns — a number most sellers never actually see. Fourth, a direct channel of your own, so the customers you already paid to acquire can buy again without the commission.
