Booking channel: native Airbnb tools may cover the core reservation workflow.

Do you need a PMS?
Not necessarily. A one-property host should buy a PMS because the workflow needs it, not because software is available. The trigger is usually multi-channel complexity, repeated manual work or plans to grow.
When to upgrade
If you are adding properties, coordinating multiple cleaners, operating across channels or losing time reconciling tools, start evaluating a PMS before the fragmented workflow becomes entrenched.
