Can my travel agency software add my own markup to supplier prices automatically?

Yes, most travel agency software lets you set your own markup so that the price your customer sees already includes what you earn, without anyone having to add it by hand on every quote.

The usual way this works is through rules you set once and then leave alone. You can normally say that hotels carry one markup and flights carry another, and you can often go finer than that, with separate rules for a particular supplier, a particular country or route, or a particular type of customer such as your sub agents or your corporate accounts. The software applies whichever rule matches at the moment the price is displayed, so the supplier cost stays behind the scenes for your own records and the customer only ever sees your selling price.

There are limits that are worth knowing before you rely on it. Some suppliers already build commission into the fare they send you, so adding a markup on top can quietly double up on what you are earning. Airline fares in particular come with rules about how they may be displayed, and on some fare types there is very little room to move. Whether you can set a flat amount, a percentage, or both together usually depends on your plan and on how each supplier returns its pricing.

Before you go live, run a few test searches with your rules switched on and compare what the customer sees against what the supplier actually quoted, and check that your invoices and reports still show the supplier cost and your own earnings as separate figures.
