Issuing a ticket is simple. Keeping the operation under control as the company grows isn’t.
When evaluating corporate travel management platforms, most companies focus on price and visible features. Few stop to examine a factor that has a direct impact on real operating cost over the medium term: the architecture behind the platform.
That’s where an open model sets itself apart. It isn’t an isolated technical feature. It’s a structural decision that shapes how a company buys tickets, chooses suppliers, and sees its own data.
Complexity grows along with the operation
When a company is small, booking a trip tends to be trivial. The real challenge shows up later: department-specific internal policies, multi-level approval workflows, operations across different countries, partner agencies, cost centers, compliance, and auditing all enter the flow at once.
The pain point stops being just about booking. It becomes about approving, controlling, auditing, and keeping everything running at scale, without the system turning into a bottleneck. That’s exactly where platform architecture, open or closed, makes a practical difference.
What an open model means in practice
An OBT with open architecture connects, via API, to multiple travel content suppliers and to different corporate travel agencies chosen by the client. A closed model, by contrast, limits those connections to a pre-defined set, usually controlled by the technology vendor itself.
No exclusive vendor
On closed platforms, the company is limited to the content and negotiated rates built into the software itself. That reduces the ability to compare options and, in many cases, rules out keeping an already established, preferred TMC as a partner.
With an open model, integration happens with whichever supplier ecosystem makes sense for the operation, without depending on a single mandatory intermediary.
No markup baked into fares
Another relevant technical point is how fares reach the end user. In closed architectures, it’s common for the technology’s margin to be baked into the price of the ticket or the room rate itself, with no transparency on how much of that value corresponds to the supplier’s actual fare.
With a fee structure kept separate from the fare, the company pays for the technology explicitly, and the trip’s price reflects exactly what was negotiated with the supplier. That separation makes auditing, cost comparison, and future negotiation much easier.
Why a closed model limits the operation
When all the booking technology belongs to a single vendor, the company loses leverage on two fronts: with the platform itself, since switching systems means rebuilding every integration, and with travel suppliers, since the catalog of options is defined by a third party.
That kind of dependency tends to compound as the operation grows. Corporate travel software has become nearly essential in the TMC market, and choosing a closed architecture at this stage can limit how much an agency or corporation can scale later on.
Transparent data as a competitive advantage
Beyond the commercial angle, there’s an equally important technical argument: the quality and traceability of the data the operation generates.
Full cost visibility
In an open model, every booking carries clear information on fare, service fee, and originating supplier. That enables detailed audits, spend-pattern identification by cost center, and historical price comparison by route or supplier.
Companies that track quality indicators in corporate travel to monitor performance depend directly on that transparency. Without it, most of the analysis turns into estimation, not real data.
The impact on choosing a TMC and suppliers
For a TMC, running on an open-architecture OBT means being able to serve multiple clients without getting locked into a single set of suppliers.
For the corporation, it means keeping the freedom to negotiate directly with specific airlines, hotel chains, or car rental companies, instead of letting the technology become a forced intermediary in that relationship.
It’s worth reviewing what to consider before hiring OBT software, specifically checking whether the architecture allows that flexibility or creates dependence on a single vendor.
Argo Travel: the numbers behind the open model
Argo has run on open architecture since its inception, connecting to more than 35 content providers across air, lodging, car rental, ground transportation, and payments, plus more than 200 partner corporate travel agencies across Latin America.
According to reporting from Brazilian outlet Baguete, Argo Solutions processed over R$6 billion (roughly $1.1 billion USD) in air tickets in 2024 alone, operates in 16 countries, and was chosen by three of the four largest global consulting firms (the Big Four) to manage their travel and expenses in Brazil.
That kind of validation typically follows platforms where governance, compliance, and data transparency have already been tested at scale.
This model also moves the operation closer to the concept of Travel as a Service, where bookings, financial data, and suppliers flow in a connected way, instead of being locked inside a closed, proprietary architecture.
Before choosing between platforms, it’s worth running a technology checklist for travel management that specifically evaluates this openness criterion, not just surface-level price or features.
A model that adapts to your company’s policies tends to support growth. A model that looks simple at first but restricts suppliers and hides markup tends to become a limitation sooner than expected.
