How a request arrives from your widget, which emails are sent, and how to confirm, edit, cancel or filter it in Inquiries.
In Rentals the guest doesn't pay in the widget: they send a request with their dates, configuration and number of guests. You review it and confirm it.
From then on, those dates are taken on the widget calendar so no one else can request them.
In the Rentals module, click Inquiries. You'll see the reference, property and configuration, check-in, check-out, nights, guest, number of guests and total.

Use Check-in from, Check-in to, Property and Status and click Filter.
The button in the Status column shows whether the request is a Request (pending) or Confirmed. Click it to confirm; click again to set it back to pending.
When you confirm it, the guest receives a "Booking confirmed" email with their stay details. You agree on the payment directly with them.

Click the pencil button (Edit) to change the dates, configuration, number of guests, guest details, notes, total or status. The nights are calculated automatically.
Click Save changes.

The Effective column is an internal mark (✅ / ⬜) to keep track of the rentals that actually took place. Click to turn it on or off.
If a request doesn't go ahead and you don't want to keep it, delete it with the trash button. Its dates are freed in the widget.
If you use a CRM or your own system, you can receive each request by webhook. Set it up in My Business, under Webhooks.
