Can I set a different markup for hotels in different countries instead of one markup for everything?

Yes, in most setups you can run several markup rules side by side rather than one blanket figure across your whole hotel inventory. This is a normal requirement, because the margin that works in a long haul leisure destination is rarely the right one for a city hotel you sell to corporate clients, and a single rule usually leaves you either too expensive or too thin.

The way it generally works is that you set a default markup that catches everything, then add narrower rules on top of it for the cases you care about. Those rules are commonly built around the destination country or city, the supplier the rate came from, the hotel category, or the travel dates, and each one can be a percentage or a flat amount per booking or per night. Where two rules could apply, the more specific one normally takes priority, so a country rule gives way to a city rule.

Be aware that what you can do depends on your plan and on the terms attached to each hotel source, so it is worth confirming before you build a complicated structure. Some suppliers place conditions on how their rates may be displayed or marked up, and rates where the guest settles directly at the hotel cannot carry your margin inside the room price, so those are usually handled as a separate service fee instead.

The practical next step is to write down the destinations and client types where your current margin feels wrong, decide on a sensible default, then ask us to confirm which rules your connected hotel sources permit and run a few test searches to check the selling prices come out as you expect.
