Your new booking engine combines a number of advantages:
It's real-time:
Every new Offer, Price, Promotion or Option that you create or modify appears immediately on your booking engine (unless you have set later publication dates),
Every time you make a reservation on your site or on one of the channels with which you are associated (Booking, Airbnb, Expedia, TripAdvisor, etc.), your availabilities are updated automatically
It is responsive, which means that it adapts to all reading formats:
Desktop (large computer screens)
Tablet
Mobile phone
It is in postpaid mode, which means that, like the vast majority of booking portals, the customer does not pay at the time of booking:
Customers do not pay at the time of booking, which gives them greater security
But they do give their bank details as a guarantee... which makes you more secure
