How can I ensure that the correct prices have synced to a channel before activating a new rate plan or connection on Booking.com?

Before creating and mapping a new rate plan, check the Rates and Availability calendar in Zeevou to ensure the output matches your expectations. Make sure any Rate Rules you need are applied. You can also place a temporary Stop Sell on the new rate plan until the connection is live and the rates display correctly on Booking.com. Once everything looks fine, remove the Stop Sell.
