Stripe & Adyen integration

Travel payment gateway integration company

Paying for travel is uniquely messy. Money comes months before the trip, gets split among multiple suppliers, and often requires partial refunds when plans change. Standard checkouts can't handle that. COAX Software is a travel payment gateway integration company that connects Stripe and Adyen to travel money movement: deposits and balances, currencies, refunds, and authentication rules.

Our travel agent payment gateway solutions and services

Stripe and Adyen checkout

Cards, Apple Pay, Google Pay, and local methods run through hosted payment fields. Card numbers go straight to the provider, so your own servers stay out of the sensitive part.

Authentication without the drop-off

European cards often require Strong Customer Authentication. We set up 3D Secure 2 with the right exemptions, so legitimate buyers see fewer extra steps and fraud still gets stopped.

Deposits, balances, and installments

A safari booked a year ahead rarely gets paid in one go. Deposits, scheduled balances, and installment plans run automatically, with reminders before every charge.

Split payments and supplier payouts

One traveler payment can cover a hotel, a guide, a transfer, and your commission. Each party receives its share on schedule, and every split is recorded.

Prices and payouts in several currencies

Travelers pay in their own currency, and suppliers get paid in theirs. Exchange handling and local payouts are configured per market.

Travel agent payment gateway solutions

Agents can send clients secure payment links, take deposits on their behalf, and track what’s owed per booking, all inside your platform with permissions set per agency.

Refunds, cancellations, and disputes

Partial refunds follow your cancellation rules automatically. When a chargeback arrives, booking terms, acceptance timestamps, and messages are bundled as evidence.

Recurring passes and memberships

Route passes, travel clubs, and memberships renew on their own. Travelers get advance notice, and failed charges retry before access changes.

How a travel industry payment gateway goes live

Get an estimate

1

Follow every euro

We trace how money moves from travelers to you, to suppliers, and back on refunds.

  • Deposits, commissions, taxes, and currencies all get mapped.

  • Weak points in the current flow are marked.

Deliverable: money flow map

2

Choose providers and account structure

Stripe, Adyen, or both are compared against your markets and volumes.

  • Who acts as merchant of record is settled.

  • Provider onboarding starts early, since travel reviews take time.

Deliverable: provider recommendation, account setup plan

3

Design the checkout and the ledger

Checkout steps, payment methods, and authentication rules are designed.

  • Every charge, split, and refund gets a matching ledger entry.

  • Finance reviews the structure before code is written.

Deliverable: checkout design, ledger specification

4

Build and test in sandbox

Test cards cover approvals, declines, 3D Secure challenges, and partial refunds.

  • Installment schedules are run through fast-forwarded time.

  • You try every scenario yourself.

Deliverable: tested payment flows, scenario log

5

Launch in stages

New payments start on a share of traffic or one market.

  • Approval rates and errors are watched hour by hour.

  • The rest follows once results hold.

Deliverable: staged rollout, launch report

6

Reconcile and tune

Payouts and ledgers are matched against provider reports.

  • Decline reasons and dispute outcomes guide improvements.

  • Finance gets clean exports for accounting.

Deliverable: reconciliation reports, tuning plan

Why finance teams breathe easier after launch

Card data kept off your servers

Hosted fields and tokens mean raw card numbers never reach your systems, which keeps your PCI DSS compliance work far lighter.

Security processes certified to ISO/IEC 27001

API keys, webhook secrets, and payout settings are handled under audited information security controls.

Releases checked to ISO 9001 standards

Every change to checkout, splits, or refunds goes through documented testing before it touches real money.

Infrastructure by AWS-certified architects

Payment webhooks, ledgers, and reconciliation jobs run on infrastructure planned for peak sales days.

Why travel businesses choose COAX Software to integrate a payment gateway for travel website

We’ve moved a live marketplace between providers

Re:Plan switched from MangoPay to Stripe and added three payout currencies with zero service interruption. Provider changes don’t have to mean downtime.

Comfortable with unusual payment schedules

Krytter’s trips are booked years ahead and paid in installments, with reporting in both Cash and Accrual accounting. Long, complex payment timelines are familiar ground.

Checkouts built to keep buyers going

Wallets, saved cards, and smart authentication cut friction at the step where most travel bookings fail. More approved payments, fewer abandoned carts.

Ledgers your accountant can follow

Every charge, split, refund, and payout leaves a matching record. Month-end reconciliation becomes a report, not a project.

FAQ

COAX Software does. As a travel payment gateway integration company, we build checkouts, deposits, installments, split payouts, and refund logic on Stripe and Adyen for booking platforms, marketplaces, and agencies.

Yes, and it’s worth planning carefully. Payment providers sometimes ask travel sellers for reserves or delayed payouts on future-dated trips. We help you prepare for those reviews and design deposit and balance schedules that keep cash flow predictable.

Several firms offer it. COAX is a travel payment gateway integration company with travel payment systems already in production, including Re:Plan’s move to Stripe across three payout currencies, plus ISO/IEC 27001 and ISO 9001 certification.

COAX can. We map how money flows through your platform, design the checkout and ledger together, and build in sandbox before launching in stages. Existing bookings and payouts keep running during the switch.

Use hosted payment fields and tokens, so card numbers go straight to the provider and never pass through your servers. That keeps the payment gateway for travel website checkouts we build within the lightest compliance scope available to most merchants.

COAX develops booking engines, marketplaces, and portals with payments designed in from the start. Installments, supplier splits, and multi-currency payouts become part of the product’s core rather than an add-on later.

Look for a travel payment gateway integration company that understands deposits, supplier payouts, and refunds tied to cancellation rules, and can show a provider migration it has handled. COAX meets those criteria and backs them with a 4.9/5 Clutch rating.

Stripe is quick to set up and works well for marketplaces and growing platforms. Adyen often suits larger businesses with high volumes and many local payment methods. Some companies use both, routing payments by market, and we’ll help you compare costs and coverage.
