Once you have received an order, you print the picking list and pack it with the product if possible. No advertisement, no invoice or other similar document may be added to/on the shipment – only the picking list should be included.
The shipment must then be dispatched within 24 hours (working days) from when you received the order.
If you manage your orders via Merchant Center, you should then mark the order as processed once it has been handled and add the appropriate shipping tracking ID. This ensures a great customer experience and reduces inquiries concerning the order status.
