Most people think a travel agency simply buys low and sells high. That is one way it earns, but a B2B agency has several distinct revenue levers, with the ones you never see often where the real profit sits. This guide breaks down exactly how a B2B travel agency makes money.
A B2B travel agency makes money through five main levers. Markup is the amount it adds to a supplier rate before selling it on. Supplier commission is what the supplier pays the agency for the booking. Pass-on commission is splitting that commission with a sub-agent to keep them competitive while still earning. Volume overrides are bonuses a supplier pays once the agency sends enough business. And service or handling fees are direct charges for the agency’s service. Understanding all five, rather than just markup, is what separates a thin-margin reseller from a genuinely profitable agency.
Written for B2B travel agency owners and founders
Ask most people how a travel agency earns and they will say it marks up the price. That is true, but it is only the most visible part of the picture, often not the most profitable. A B2B travel agency, one that sells to other agents rather than direct to travellers, has a layered revenue model where several levers work together. The agencies that thrive are the ones that understand and pull all of them rather than relying on markup alone.
This guide is written for the owner who wants to understand every way their business makes money, so they can grow the levers that matter. It breaks down the five revenue levers of a B2B travel agency, explains where each one comes from and shows how the pricing tools inside B2B travel agency software let you control them. The pricing mechanics behind several of these are covered in our guide to markup and margin control.
The buy-low-sell-high view of a travel agency captures markup and nothing else, which is why so many agency owners feel their margins are permanently thin. If markup is your only lever, you are locked in a race to the bottom with every competitor buying the same inventory, because the only way to win a price-sensitive booking is to add less. That is a hard, low-margin way to run a business. It is the trap agencies fall into when they see themselves purely as resellers.
The agencies that escape that trap treat revenue as a portfolio. Markup is one contributor, but supplier commission, pass-on economics, volume overrides and service fees all add to the total, while several of them reward exactly the thing markup punishes, which is volume. Once you see the full set of levers, the goal stops being to squeeze more markup out of each booking and becomes to build the volume and relationships that unlock the other four. The rest of this guide takes them one at a time.
Markup is the most familiar lever, the amount an agency adds to a supplier rate before selling it on. Buy a room at a net rate, add your margin, sell it at the higher price and keep the difference. It is simple and it is real revenue, but its weakness is that it is the most visible and most competed part of your pricing. On any given booking, a competitor can undercut you simply by adding less, so markup on its own tends toward thin margins in a competitive market.
The skill with markup is not to apply one flat number but to vary it intelligently, setting different markups per supplier, per channel and per date so each booking carries the margin its context can bear. A deeply net rate can take a fuller markup than a retail-priced feed, a corporate channel can be priced differently from a public one, while a peak date can carry a surcharge a quiet date cannot. Used with that precision, markup becomes a sharper tool than a single blunt percentage, as we explain in our guide to markup and margin control.
Supplier commission is money the supplier pays the agency for making the booking, separate from any markup. Many suppliers offer commissionable rates, where a booking earns the agency a percentage back from the supplier, so the agency can earn even on a rate it sells at or close to face value. This is a fundamentally different lever from markup, because the earning comes from the supplier side rather than the customer side.
The important consequence is that a smaller booking on a high-commission supplier can be more profitable than a larger booking on a low-commission one, even though the larger booking looks better on a revenue report. This is why seeing commission alongside revenue matters so much, since an agency that optimises purely for gross booking value can be leaving real money on the table. Understanding your true commission by supplier, agent and destination is part of what our guide to B2B travel portal analytics covers.
Control markup, commission, pass-on and fees per channel from one platform.
See the B2B Travel Portal →Pass-on commission is the lever that makes distribution work. When an agency resells to sub-agents, it can take the supplier commission on a booking and split it, keeping part as its own margin and passing part on to the sub-agent to sharpen the rate they see. This keeps the sub-agent competitive against buying direct from an aggregator, which drives their volume, while the agency still earns on every booking they make.
The clever part is that pass-on turns a bigger network into more revenue rather than thinner margins. A more generous split makes a sub-agent more competitive, so they book more and the agency earns more in absolute terms even at a smaller cut per booking. Setting the split per agent lets you invest more in your best relationships and less in casual ones, which turns commission sharing into a deliberate growth engine. This is the core economics of the reselling model, covered further in our guide to per-channel pricing.
An agency splits supplier commission with its sub-agents, keeping half and passing half on. For its highest-volume agents it moves to a more generous split, keeping less per booking but making those agents sharper on price. Their volume rises enough that the agency earns more in total from them than it did on the tighter split, because a bigger share of a much larger number beats a bigger share of a small one.
A volume override is a bonus a supplier pays an agency for reaching an agreed level of business, on top of the standard commission. Overrides reward scale directly. Once you send a supplier enough volume, they pay you an extra percentage, sometimes retroactively across all the bookings in the period, which can turn a good supplier relationship into a very profitable one. This is a lever that markup can never provide, because it comes purely from concentration of volume.
The catch is that you only earn an override if you actually reach the threshold, which happens only if enough of your volume flows to that supplier. This is where result ordering and preferred-supplier promotion earn their keep, because steering volume toward an override supplier is what triggers the bonus. It is also why knowing your true volume per supplier matters, since you cannot manage toward a threshold you cannot see. An override is often the single most profitable lever an agency has, precisely because so few manage deliberately toward it.
The fifth lever is the most direct, a fee the agency charges for its service rather than building margin into the rate. This might be a booking fee, a handling fee on a particular channel or a charge for a value-added service. Fees are transparent by nature, which suits some audiences better than others. A corporate client often prefers a clear service fee to a hidden markup, because it can see and account for exactly what it is paying you for.
Because different audiences accept fees differently, the ability to apply them per channel matters. You might charge a handling fee on one channel and not another, then present a transparent fee to a corporate account while using markup on your public site. Matching the fee model to the audience is what makes this lever work without driving business away. It fits within the same per-channel pricing structure that carries your markup and commission settings.
The real skill is not any single lever but the mix. A profitable B2B agency uses markup where the audience will bear it, earns supplier commission wherever rates are commissionable, shares that commission through pass-on to grow its network, steers volume to unlock overrides and adds transparent fees where they fit. No one lever carries the business. The profit comes from combining all five, weighted to your audiences and your supplier relationships.
What makes this manageable is having all the levers in one platform, set per channel, with the reporting to see how each is performing. When markup, commission handling, pass-on splits and fees all live in the same system, with your analytics showing the true earning behind every booking, you can tune the mix deliberately rather than guessing. That is the difference between an agency that survives on thin markup and one that builds real, layered profit. To see how these revenue tools sit within the wider platform, start with the pillar guide to B2B travel agency software.

Through five main levers. Markup is the amount added to a supplier rate before selling it on. Supplier commission is what the supplier pays the agency for the booking, separate from markup. Pass-on commission is splitting that commission with a sub-agent to keep them competitive while still earning. Volume overrides are bonuses a supplier pays once the agency sends enough business. And service or handling fees are direct charges for the agency’s service. The profitable agencies use all five, weighted to their audiences and supplier relationships, rather than relying on markup alone.
Markup is money you add on the customer side, the amount you put on top of a supplier rate before selling it. Commission is money you earn on the supplier side, a percentage the supplier pays you for making the booking. They are different levers, so a booking can earn both. The practical consequence is that a smaller booking on a high-commission supplier can be more profitable than a larger booking on a low-commission one, even though the larger booking looks better on a revenue report, which is why it pays to see commission alongside revenue rather than optimising for gross value alone.
Pass-on commission is when an agency reselling to sub-agents takes the supplier commission on a booking and splits it, keeping part as its own margin and passing part on to the sub-agent to sharpen the rate they see. It keeps the sub-agent competitive against buying direct from an aggregator, which drives their volume, while the agency still earns on every booking. A more generous split makes an agent more competitive and grows their volume, so the agency can earn more in absolute terms even at a smaller cut per booking. Setting the split per agent turns commission sharing into a deliberate growth engine.
A volume override is a bonus a supplier pays an agency for reaching an agreed level of business, on top of the standard commission. Once you send a supplier enough volume, they pay you an extra percentage, sometimes retroactively across all the bookings in the period. It is a lever markup can never provide, because it comes purely from concentration of volume, which is why steering volume toward a preferred supplier and knowing your true volume per supplier matter so much. An override is often the single most profitable lever an agency has, precisely because few manage deliberately toward it.
It depends on the audience, which is why being able to do either per channel matters. A service or handling fee is transparent, so a corporate client often prefers it to a hidden markup because it can see and account for exactly what it is paying for. A public leisure customer may respond better to a competitive all-in price with the margin built in as markup. Matching the fee model to the audience, charging a fee on one channel and using markup on another, is what makes this lever work without driving business away.
