Can I give other travel agents their own login to book through my white label travel portal?

Yes, in most cases you can give other travel agents their own login so they book through your portal instead of coming back to you by phone or email every time. This is usually called a sub agent or B2B setup, and it gives each agent a separate username, their own list of bookings and their own record of what they have sold. You stay the owner of the portal and of the supplier relationships, while they work inside the site you control.

What each sub agent can see and do is normally up to you. You can decide which products they are allowed to sell, such as flights only or flights and hotels together, and you can set the markup or commission that applies to their bookings so the price they see already includes your margin. You can also switch an agent off if they stop working with you, and their past bookings stay on your records.

How they pay you is the part worth checking early, because it varies. Some setups let a sub agent hold a credit balance with you that goes down as they book, while others ask them to pay for each booking as they make it. Which of these you can offer depends on the plan you are on and on what your payment provider and your suppliers allow, so it is better to confirm it than to assume it.

The sensible next step is to write down how you want your agents to pay you and what you want them to be able to sell, then ask whoever manages your portal to confirm that both can be set up the way you have described.
