Are there any pricing and markup engine tools that handle GDS connectivity and secure payments?

Yes—there are tools in the airline/travel pricing and markup space that can handle GDS connectivity and also support secure payments, though the exact combination depends on whether you mean:

1. A pricing/markup engine for OTA or travel agency use, or
2. An airline retail/pricing engine with distribution and payments capabilities.

Common categories of solutions

1) Travel pricing / markup engines with GDS integration

These typically connect to systems like Amadeus, Sabre, and Travelport and let you:

• apply markups, commissions, fees, or dynamic pricing rules
• manage channels, markets, customer segments, or supplier-specific pricing
• sometimes bundle ancillaries or package pricing

Examples in the broader market include:

• AirGateway
• Travelfusion
• TBO / API aggregators
• Duffel (more offer/order focused than classic markup engine)
• Amadeus, Sabre, Travelport partner ecosystems

2) Secure payment platforms used alongside pricing engines

Secure payments are often handled by a separate module or integrated payment layer. Common capabilities include:

• PCI DSS compliance
• tokenization
• 3DS / SCA support
• virtual cards / card vaults
• fraud screening
• support for split payments, refunds, and reconciliation

Common providers used in travel include:

• Adyen
• Worldpay
• Checkout.com
• Stripe
• Nuvei
• CellPoint Digital
• Fly Now Pay Later / BNPL options depending on use case

Platforms that combine both more directly

Some travel commerce platforms combine:

• inventory access / booking APIs,
• pricing/markup rules,
• checkout and payment orchestration.

These are often positioned as:

• travel retailing platforms
• booking engines
• offer and order management platforms
• payment orchestration platforms for travel

What to look for in a vendor

If you want both GDS and secure payments, ask for:

• direct GDS certification or certification via aggregator
• dynamic pricing/markup rules
• PCI DSS Level 1 compliance
• tokenized card storage
• 3DS2 / SCA support
• chargeback/fraud tools
• support for multi-currency and settlement

If you want, I can give you:

• a shortlist of vendors by category,
• a comparison table,
• or recommendations based on your model: OTA, corporate travel, airline, or travel agency.
