To ensure PriceLabs can successfully sync prices to your listing, Smoobu must display at least one year of future pricing and availability. If you receive an error from PriceLabs indicating missing pricing or availability, please:
Check your Smoobu calendar to make sure the Standard Price row (not just the portal-adjusted rows) has rates entered.
Ensure both the pricing and stay requirements are filled in for each date.

Once everything is set, return to PriceLabs and click “Save & Refresh” on your Pricing Calendar. If your listing already includes this information and the error persists, please submit a support ticket so we can assist you further.
Booking.com Monthly View When Connected Through Smoobu
When a Booking.com listing is connected to any API partner—including RMS or PMS platforms—the
monthly calendar view in Booking.com becomes unavailable. Users will only be able to access the
list view and
yearly view of the calendar. This is
expected behavior on Booking.com’s side and applies universally to listings integrated via API.
