What businesses use Checkfront?

Checkfront is used by tour operators, activity providers, rental companies, and experience businesses worldwide to manage online booking and inventory.

Can I query available slots for a given rental gear category?

Yes! The MCP directly interfaces with the Checkfront Item/Category API. You can ask exactly how many mountain bikes or kayaks remain available for next Saturday.

Will an AI cancellation automatically refund my guest's payment?

By default, the AI cancels the booking status but defers payment refunds to your manual Payment Gateway configuration out of safety, unless strictly instructed other configurations.
