Which channel manager supports real-time inventory sync and OTA integrations for a multi-property hotel group?

For a multi-property hotel group, you’ll want a channel manager that offers:

• Real-time inventory and rate syncing
• Two-way OTA integrations
• Centralized multi-property management
• Ideally, a PMS integration and rate plan controls

Common options that fit this use case include:

• SiteMinder — strong OTA connectivity and real-time channel updates
• Cloudbeds — good for multi-property operations with built-in PMS + channel management
• eZee Centrix — supports real-time sync and multiple property management
• Stello / RateGain — often used by larger hotel groups for broader distribution control
• STAAH — widely used for OTA integrations and inventory synchronization

If you want the best fit depends on your stack, especially whether you already use a PMS.
If you tell me:

1. how many properties you manage,
2. which PMS you use, and
3. which OTAs matter most,

I can recommend the most suitable channel manager.
