Can I stop my staff from seeing how much I actually paid the supplier for a booking?

Yes, in most setups you can keep your net cost hidden from your staff and let them see only the selling price your customer pays. This is usually handled by giving each person a role, so a counter agent or a junior booking staff member sees the search results, the customer price and the booking details, while the cost price, the markup settings and the profit figures stay with you and anyone else you choose to trust with them.

What you can hide and how finely you can control it does depend on your plan and on how your account is configured, so it is worth confirming the exact permissions available to you rather than assuming every screen can be locked down. In general the areas people most want to restrict are the markup rules, the profit and margin reports, and the accounting or supplier statement pages, and those are the ones that are most commonly separated out by role.

There is one honest limit to keep in mind. Anything that comes directly from a supplier, such as a confirmation email, a supplier voucher or a document a staff member downloads from an outside portal, is outside the control of your own system. If a staff member has direct access to a supplier login or receives supplier emails, they may well see net amounts there, so the practical answer is to control who holds those supplier logins as carefully as you control the roles in your software.

The next thing to do is list the staff you have and decide what each one genuinely needs to see, then ask us to set their roles to match and test it by logging in as one of them yourself.
