When generating a Quote for a customer, you can send them a link in the Quotation email that allows them to confirm and pay for the Booking online.
Create a new Enquiry as per guide here.
Fill in all the relevant details and Search.
Add a property.
Select the Bookable Online check box.
This will bring up the Expires At field. This defaults to 24h, but you can change it as you see fit.
Note that this is how long the link is valid for. It does not have anything to do with how long a property is held for. In order to hold the property, you will also need to use the Hold for functionality.
The Quote email will have a link in it for the customer to use. It will also state that the quote expires at the time set for the Bookable Online. Send the email.
When the user clicks on the link, they will be able to confirm the quote selection, enter their card details and pay directly for the Room Stay. This will update the Room Stay in Rerum to confirmed status.
Note that if the link has expired, they will instead be redirected to a page encouraging the user to contact your business to secure a different quotation.
