Scandinavian simplicity in online payments

project info

LOCATION: Denmark
INDUSTRY: Fintech / Ecommerce
DOMAIN: Payment Gateway Integrations

Quickpay is one of Denmark’s most trusted payment service providers, known for its robust API, fast onboarding, and wide support for European and global payment methods.
To support more merchants and storefronts across diverse platforms, Quickpay required high-quality, compatible, and secure plugins for multiple e-commerce systems.
Genuineq contributed to the Quickpay ecosystem by developing and improving payment plugins across major e-commerce platforms, helping merchants across Europe process secure, reliable online transactions.

the challenge

Quickpay’s strength lies in its API and platform flexibility – but to reach merchants at scale, payment providers must offer ready-to-use, reliable plugins across the e-commerce ecosystem.
Ensuring a consistent payment experience required extensive testing, platform-specific optimization and understanding of payment flows and merchant environments.

the solution

Genuineq implemented and extended payment modules for several e-commerce environments: WHMCS, osCommerce, PrestaShop, Ecwid, OpenCart.

Genuineq contributed by adding and improving merchant configuration interfaces (API keys, live/test modes, authorization options) and support for refunds and recurring payments.

testimonial

What made Quickpay stand out as a technical project was the scale of its plugin ecosystem. Each platform has its own rules, constraints, and expectations, and our job was to make the payment experience feel identical everywhere. We focused on writing integrations that were clean, maintainable, and predictable - the kind developers and merchants can trust long-term.
