Your marketplace handles 50 properties fine.
Then you add 200 more, and the availability sync starts breaking.
Rooms are available on your platform, but are sold out at the property. Prices update on the supplier side but stay stale on yours for 6-12 hours. Double bookings start happening.
Most teams try faster polling. Doesn't work. Because the problem is treating inventory as a data feed instead of a live state.
Travel inventory changes constantly:
▪️Room sold on Booking.com ▶️ your platform should know in seconds, not hours
▪️Price drops for last-minute availability ▶️ needs to propagate immediately
▪️Cancellation opens inventory ▶️ every channel should see it simultaneously
We built a marketplace that handles 14,000+ vendors, and inventory conflicts dropped 87% after the rebuild. The fix wasn't faster polling. Event-driven sync architecture.
Your inventory system should react to changes, not search for them.
How often does your platform show availability that doesn't exist? 👇
