Rates and availability are automatically sent from Sirvoy to the booking channels, whenever a change occurs in Sirvoy.
All seasonal rates or alternative price lists registered in Sirvoy will be considered when rates are sent to the booking channels. However, discounts for longer stays will not be accounted for since that type of pricing is not supported by most channels. On top of that you can add a certain percentage to the price that is sent to some channels under “Adjust prices in update” in Settings -> Channels -> (Selected Channel) -> Connect.
