Can I add my own markup to the prices my supplier sends, and change it for different customers?

Yes, you set your own markup and you can charge different customers differently. The markup sits between the price your supplier returns and the price your customer sees, so what appears on your website is already your selling price. You normally choose whether it is a percentage of the fare or a flat amount per passenger or per booking, and you can usually keep separate rules for flights and for hotels, because the two behave differently.

Most systems let you go further than one blanket rule. Depending on your setup you can vary the markup by airline, by supplier, by route or country, by cabin or room type, or by who is logged in, so a customer on your public website and a sub agent using your B2B panel do not see the same price. Many agencies keep a lower rule for corporate accounts that have agreed a fixed service fee with them.

It is worth knowing the limits. A markup only applies to the part of the price your supplier allows you to change, so taxes and certain airline fees usually pass straight through, and some negotiated fares carry rules about what you may add on top. Whether you can stack several rules, or add a separate service fee alongside the markup, depends on your plan and on the suppliers connected to your portal.

Before you go live, set one simple rule, run a few real searches and compare what your customer sees with what your supplier returned, and put a cancellation through as well so you know how your markup is treated when money goes back to the customer.
