Planning the first version of your OTA: what to build first

The first version of an online travel agency should be small on purpose: one product, one supplier, one market and one customer group, built properly, with some rare processes handled by hand at first. This kind of OTA MVP, or minimum viable product, lets you launch sooner, spend less before you have real customers, and learn what to build next from actual bookings rather than guesses. What it must never cut is accuracy, payment safety and the tools your team needs to fix problems.

An OTA sells travel, such as flights, hotels or tours, through its own website. A minimum viable product is the smallest version that real customers can use and pay for. This guide explains how to decide what goes into the first version and what waits. If you are planning a travel platform, our OTA platform service page explains how we build them.

Why a smaller first version is safer

Travel platforms are complex. Each product, supplier and market adds integration work, testing, certification and support. Trying to launch everything at once multiplies the risk.

• Faster to market. A focused scope can launch far sooner, so you start learning from real customers earlier.
• Lower initial spend. You spend less before proving that customers want what you offer.
• Better quality. A small platform can be tested thoroughly, including failures such as sold-out fares and timeouts.
• Easier supplier certification. Passing one supplier's review is simpler than coordinating several at once.
• Clearer lessons. With fewer moving parts, it is easier to see what works and what does not.
• Room to change direction. If customers behave differently from your expectations, a smaller platform is easier to adjust.

A smaller first version is not a lower-quality version. It is a narrower one.

A worked example

Compare two possible first versions for the same agency:

The focused version still needs payments, confirmations, an admin panel and logging, but everything else is a fraction of the work. Once it is live and taking bookings, adding a second supplier or product builds on foundations that are already proven.

Choosing one product and one supplier for your OTA MVP

The most important scoping decision is what you sell first and where it comes from.

Choose one product

Pick the product that best matches your strengths and your customers:

1. Flights suit agencies with strong route knowledge or a loyal customer base that books air travel.
2. Hotels suit agencies focused on a region or on leisure travellers who book stays.
3. Tours or packages suit operators who create their own products and control availability.

Each product has its own booking flow, supplier logic and documents. Adding a second product later is easier once the platform's foundations are proven.

Choose one supplier

Choose a supplier that:

• Covers your chosen markets and routes or destinations well.
• Offers reliable test access and clear documentation.
• Has commercial terms that suit your expected volume.
• Provides support you can reach when bookings go wrong.

Design the platform so a second supplier can be added later without rewriting the site. Converting each supplier's data into your own format from the start makes that possible.

Choose one market and customer group

Serving one country, one language and one currency first keeps design, content, payments and legal work manageable. Decide whether your first customers are travellers or travel agents, because the features they need differ.

Manual processes you can keep at the start

Not every task needs full automation on day one. Handling rare or complex cases by hand can save a lot of development time early on.

1. Unusual cancellations and changes. Your team can process these through the admin panel and the supplier directly, while standard cancellations are automated later.
2. Complex refunds. Partial refunds with special conditions can be calculated by your team at first.
3. Group bookings and special requests. These can go through an enquiry form rather than the booking engine.
4. Some reports. Exports to a spreadsheet can cover reporting needs until you know which reports matter.
5. Supplier reconciliation. Matching supplier invoices with bookings can start as a regular manual check.
6. Marketing features. Loyalty schemes, referral codes and personalisation can wait.

Keep a list of every manual process and how often it happens. When a task becomes frequent, it is a good candidate for automation in the next phase.

What must be right from day one

Some parts of the platform cannot be simplified without putting customers, money or your reputation at risk.

1. Accurate prices. Check fares or rates with the supplier before booking and show any change honestly.
2. Safe payments. Use a reputable payment gateway, keep card details off your systems and, where possible, collect payment only once the booking is confirmed.
3. Reliable booking handling. Never retry bookings blindly after a timeout; check status with the supplier and flag unclear cases.
4. Clear confirmations. Customers must receive accurate confirmations, e-tickets or vouchers.
5. Logging. Record every supplier request and response, linked to the booking, with sensitive data masked.
6. An admin panel with an operations queue. Your team must be able to see every booking, spot problems and act on them.
7. Security basics. Updated software, protected admin accounts, HTTPS and backups.
8. Legal and licensing requirements for selling travel in your market.

These are the foundations everything else will be built on. Cutting them to save time usually costs more later.

Planning phase two

Plan the second phase before the first one launches, but decide its details after launch, based on evidence.

1. Track the right measures. Searches, bookings, drop-off points in the booking flow, failed bookings, support requests and margin per booking.
2. Review your manual processes. Automate the ones that take the most time or cause the most errors.
3. Listen to customers and staff. Support requests and team feedback point to the features that matter.
4. Decide on the next expansion. A second supplier for better coverage, a second product, agent accounts or a new market.
5. Budget realistically. Each addition brings integration, testing and maintenance work.

Summary

• A focused first version launches sooner, costs less and teaches you more.
• Start with one product, one supplier, one market and one customer group, designed so more can be added later.
• Handle rare cancellations, complex refunds and some reports by hand at first.
• Never simplify prices, payments, booking handling, confirmations, logging, admin tools or security.
• Plan phase two using real measures, manual workload and customer feedback.
