For each order a user makes in the Yandex.Market interface, the store pays an agency fee (commission) equal to 1% of the total price for the items sold.
The agency fee is deducted from the store's account in two stages:
The amount of the agency fee is reserved on the store's account when the order gets the status of “being processed” (PROCESSING). The store is informed of this status in a notification request from Yandex.Market, and it means the store can start processing the order.
The funds are reserved in advance so that the store's balance does not become negative when this amount is deducted.
