For property owners and managers, changing rates on Booking.com in 2026 is most efficiently done through the Extranet or the Pulse app. Once logged in, you navigate to the "Rates & Availability" tab (or "Calendar" in the app). From there, you can select a specific date or a range of dates and use the "Bulk Edit" tool to adjust your prices for different room types. You can set "Standard Rates," "Non-refundable Rates," or create "Promotions" (like Last-Minute or Early Bird deals) to react to market demand. If you use a Channel Manager (like Siteminder or Cloudbeds), you should always change your rates in that central software instead of Booking.com directly to prevent "overbooking" and ensure your pricing remains consistent across all platforms like Expedia or Airbnb. For travelers wanting to change the rate of an existing reservation, you must use the "Manage Booking" link in your confirmation email; however, this usually involves a "modification" which may subject you to the current market price rather than the original rate you booked.
