Can I send my customer a few flight or hotel options to choose from and let them pay for the one they like?

Yes, in most travel portals you can put a few options into one quote and send it to your customer as a link, so they can look at them side by side and pay for the one they prefer. You search as normal, save the options you want to suggest, add a short note about each one, and the portal builds a page in your own branding that you can email or send on WhatsApp.

What your customer sees when they open that link is the important part. A good quote checks the price again at the moment it is opened, because airline and hotel prices move on their own. That means the option may still be there at the same price, it may have gone up, or it may have sold out by then. It is far better for your customer to see that honestly on the page than to pay and have the booking fail afterwards.

Whether the customer can pay straight from the quote depends on your plan and on your payment setup. If you have a payment gateway connected, the quote can carry a pay button and the booking is made for you once the money clears. If you do not, the quote still works as a tidy way to present the choices, and you collect the payment the way you do today.

Ask your provider whether quotes are included in the plan you are on, how long a quote link stays open before it expires, and whether the price on it is refreshed live or simply frozen at the moment you sent it.
