Shift4 + Shuttle

Shift4 is a global payments and commerce technology company processing over $260 billion annually for more than 200,000 businesses across hospitality, retail, restaurants, stadiums, and ecommerce. Founded in 1999, Shift4 provides unified in-person, online, and mobile payment processing alongside the SkyTab POS system, which combines point-of-sale functionality with business intelligence, guest engagement, and loyalty tools. The platform supports over 100 payment methods and operates across 75+ countries with end-to-end encryption, tokenisation, and PCI DSS compliance.

Shuttle integrates with Shift4 to bring its processing capabilities into a multi-PSP orchestration layer. Through Voice Checkout, platforms can accept PCI-compliant phone payments that route to Shift4 for processing. Payment Links leverage Shift4’s hosted payment infrastructure, and embedded payment flows utilise Shift4’s tokenisation and broad payment method support. Shuttle passes transactions to Shift4’s API with full support for the payment methods and features available through their platform.

For platforms in hospitality, food service, entertainment, and retail verticals — where Shift4 has deep domain expertise and competitive processing rates — connecting through Shuttle provides access to Shift4’s specialised capabilities while maintaining processor independence. Platforms can route transactions to Shift4 for merchants in their core verticals while using other connected PSPs for different use cases or geographies, optimising cost and authorization rates across their entire merchant portfolio without building separate integrations.
