Until now, changes in working conditions on marketplaces could come without warning — the site changed tariffs, and the seller found out about it after the next billing period. The new norm sets up the reverse order: first the notification, then the change.
The 45—day period was not chosen arbitrarily - this is enough time for the seller to recalculate the unit economy, adjust prices on the site or, in a critical case, curtail sales using an unfavorable model before the new conditions take effect.
The rule applies to a wide range of changes: tariffs, logistics, fines, and compensation. A shorter period for notification of discounts at the expense of the platform is fixed separately — at least five business days, and the seller has the right to refuse to participate in such an action without consequences and sanctions from the marketplace.
The standard is fixed not in the unilateral disposal of the site, but in an additional agreement to the Memorandum of Good Practices, a document signed by all major market players. This makes the rule part of the general preparation for the law on the platform economy, which comes into force on October 1, 2026, and not a temporary assignment of a specific site.
The practical value of the norm for the seller is not in the fact of notification itself, but in how this notification is used. Receiving a letter of commission increase 45 days in advance and not responding before the changes take effect is the same as not receiving it at all. Sellers should set up regular checks of their personal account and mail for notifications of changes in conditions, and use the received 45 days for real recalculation of the model, rather than postponing a decision for later.
