Techtalks: Traveltech

I read (hopefully correctly) that you need to go through a channel manager to connect to booking.com but when I looked at the hotel base of a popular channel managers (e.g. Siteminder 30,000 properties and who also connect to booking.com) I'm struggling to understand how the rest of Booking.com's hotels connect. Any help / advise would be very much appreciated. 30,000 is a small number compared with the number of hotels advertised on booking.com. Please excuse my naivety as I'm new to this.

I've been running a travel business for past 5 years. We are a DMC for a specific destination.

We use multiple software products to manage our inventory of vehicles and hotel rooms.

I am now planning to develop my own portal with self-contracting hotel rooms. The challenge we now face is few hotels are unable to provide us a dedicated slot of rooms and upon investigation they replied us that a lot of rooms are booked through OTA and hence providing dedicated rooms is not possible.

Hence we decided to build a channel manager by ourselves so that we can have live inventory.

Are we going in the right direction or completely lost in technology? Please advise.
