Short answer: travel portal development cost is driven by one big choice (white label versus custom build) and a handful of multipliers: how many product modules you need, how many supplier APIs must be connected and certified, how much of the design is bespoke, whether you need B2B agent features, which payment methods and currencies you accept, whether you want mobile apps, and what hosting, maintenance and support you expect after launch. Get those defined and quotes become comparable.
Why quotes vary so much
"Travel portal" is not one product. The phrase covers a subscription white label site with a logo swapped in, a B2C booking site with two supplier feeds, and a multi-supplier B2B platform with agent hierarchies, credit limits, markup rules and a back office. Vendors hear the phrase, assume a scope that matches what they usually sell, and price that. Unless you fix the scope yourself, you are comparing assumptions, not prices.
Three other things widen the spread. First, the business model of the vendor: a subscription product is priced to recover its cost over years, a custom build is priced on the hours it takes now. Second, what is included: some quotes bundle supplier integration, hosting and a year of support, others list them as extras. Third, where the work is done and by whom. None of these makes a quote wrong, but all of them make it incomparable until you know what it contains.
The cost drivers, and how to reduce each one
The table below lists the decisions that move the price most, why each one matters and the practical way to keep it under control. The white label versus custom comparison covers the first row in detail.
| Cost driver | Why it matters | How to reduce it |
|---|---|---|
| White label vs custom build | A white label portal spreads its development cost across many customers and is configured, not built. A custom portal is built for you and you pay for every screen and rule. | Start on a white label product unless you have a workflow or product that genuinely does not fit one. Move to custom when the limits cost you bookings. |
| Number of modules | Flights, hotels, buses, holidays, visas, transfers, insurance and activities each need search, booking, cancellation and back-office screens. | Launch with the one or two modules that earn revenue now. Add others when the first ones pay for them. |
| Supplier APIs and certification | Each supplier is its own integration, test cycle and go-live review. GDS certification in particular is slow and has commercial prerequisites. | Use one aggregator that covers your routes rather than three direct feeds. Choose suppliers you can actually get production access to before the build starts. |
| Design scope | A bespoke design means research, wireframes, visual design and front-end build for every screen and device size. A template is adapted, not drawn. | Customise the template for the pages travellers see most (home, results, checkout) and accept standard layouts for the rest. |
| B2B agent features | Agent registration, approval, credit and deposit wallets, markup and commission rules, multi-level hierarchies and statements are a second product on top of the B2C site. | If you need B2B, specify the agent hierarchy depth and the settlement rules up front; retrofitting them is the expensive path. See the B2B travel portal page for what is typically included. |
| Payments and currencies | Each gateway is an integration with its own refund and reconciliation flows. Multi-currency adds rate management and rounding rules through the whole booking path. | One gateway per market, one settlement currency to begin with. Add display currencies before you add settlement currencies. |
| Mobile apps | Native iOS and Android apps are separate codebases or a cross-platform build, plus store submissions and ongoing OS updates. | Launch with a responsive web portal. Add apps when repeat customers justify them; a white label app can reuse the portal's APIs. |
| Hosting and maintenance | Supplier APIs change, security patches arrive, PHP and framework versions age. Someone has to keep the site up and current. | Agree a maintenance plan with a defined scope at quote time rather than paying ad hoc. Managed hosting usually costs less than downtime. |
| Support plans | Response times, channels and hours determine how much vendor time is reserved for you. | Match the plan to your trading hours and to how quickly a supplier outage would hurt you, not to the most expensive tier offered. |
One-time versus recurring costs
Buyers tend to fixate on the build quote and forget that a portal is a running service. The diagram shows how the two categories behave over time. One-time costs cluster around launch; recurring costs are smaller but continue for as long as you trade, and tend to grow as you add suppliers and modules.
One-time costs usually include discovery and specification, design, development, supplier integration and certification, payment gateway integration, data setup (destinations, content, markup rules), testing, deployment and training. With a white label product most of these shrink to configuration and branding; with a custom build they are the bulk of the quote.
Recurring costs include hosting and infrastructure, any licence or subscription for the platform, supplier API and transaction fees, payment gateway fees, SSL and domain renewals, maintenance to keep up with supplier API changes and security updates, the support plan, and third-party services such as email delivery, SMS, WhatsApp messaging and analytics. Subscription white label products fold several of these into one monthly figure; custom builds leave you to assemble them.
Hidden costs people miss
- Supplier deposits and credit lines. Consolidators and many B2B suppliers require a deposit or prefunded wallet before they will issue tickets. This is working capital, not a development cost, but you cannot trade without it.
- GDS and supplier fees. GDS access can involve commercial minimums, per-segment charges and certification effort; aggregator APIs may charge per booking or above a search-to-book ratio. Ask each supplier for its full commercial terms, not just the API documentation. The flight booking API comparison explains the common pricing models.
- Payment gateway fees and reserves. Travel is a higher-risk category for card processors. Expect transaction fees, possible rolling reserves and extra documentation during underwriting.
- Content and photography. Destination descriptions, hotel content beyond what the supplier feeds provide, route pages and licensed images all take time or money.
- Legal pages and policies. Terms, privacy policy, refund and cancellation policy and an accurate independent-agency statement need to be written for your business, and reviewed by a professional if you sell abroad.
- Training and change. Staff need to learn the back office, and accounting and refund processes will need adjusting to match what the portal produces.
- Marketing before revenue. A portal without traffic earns nothing. Budget for the campaigns and content that bring the first bookings; the guide to starting an online travel agency covers the sequence.
How to get quotes you can compare
Send every vendor the same brief and ask for the same breakdown. This checklist is the brief.
- Business model: B2C, B2B, or both; which markets and currencies; whether you issue tickets yourself or through a consolidator
- Modules at launch and modules planned for later, listed separately
- Named suppliers for each module, with confirmation that you can get production access to each
- Design expectation: template with branding, template with custom key pages, or fully bespoke
- B2B requirements: agent hierarchy levels, wallet or credit model, markup and commission rules, statements
- Payment gateways per market and whether multi-currency display, settlement or both are needed
- Mobile: responsive web only, or iOS and Android apps, and when
- Hosting: vendor-managed or your own cloud account, and the expected uptime and backup arrangements
- Maintenance and support: what is included, hours, response times, and what counts as a billable change
- Ownership: who owns the code, the data and the domain, and what happens if you leave
- Breakdown requested: one-time items, recurring items and third-party pass-through costs on separate lines
When the quotes come back, line them up by these headings. A quote that is much lower than the others has usually left something out; a much higher one has usually assumed a bigger scope. Either way you now know what to ask.
How we quote
Globitude quotes fixed prices against a written scope, with one-time and recurring items on separate lines and supplier and gateway fees shown as pass-through costs rather than hidden in the build. For most first portals we recommend starting with a white label travel portal and moving to custom travel portal development only when the business has outgrown it. If you already have a brief, send it through the contact page and we will return a quote against the headings above.
