Shift4 + Shuttle

Shift4 is a global payments and commerce technology company serving 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, with end-to-end encryption, tokenisation, and PCI DSS compliance.

Shuttle integrates with Shift4 to bring its processing capabilities into a multi-PSP payment layer. Through Voice Checkout, platforms can accept PCI-compliant phone payments that route to Shift4 for processing. Payment links can be processed through Shift4, and embedded payment flows use Shift4’s tokenisation.

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 put merchants in their core verticals on Shift4 while using other connected PSPs for different use cases or markets, without building separate integrations.
