Fortis + Shuttle

Fortis is a US payment technology company designed specifically for independent software vendors (ISVs) and SaaS platforms that want to embed payments into their products. Unlike general-purpose processors, Fortis has built its platform around the needs of software companies, offering flexible merchant boarding, white-label payment components, portfolio management tools, and revenue-sharing models that turn payments into a profit center for the platform. Fortis supports card-present and card-not-present transactions, ACH and eCheck processing, and recurring billing, with an API-first architecture that makes integration straightforward for development teams.

Shuttle’s integration with Fortis creates a powerful combination for software platforms operating in the US market. Platforms that already use Fortis for merchant boarding and portfolio management can connect Fortis through Shuttle to gain multi-channel payment capabilities. Shuttle’s Voice Checkout product processes phone-based payments through Fortis’s tokenization and processing infrastructure, which is especially relevant for vertical SaaS platforms in industries like healthcare, home services, and professional services where phone-based payments remain a significant transaction channel. Payment Links powered by Fortis through Shuttle give platforms an instant way to collect payments via email or SMS without building custom checkout pages.

For ISVs and SaaS platforms that have chosen Fortis as their primary US processor, accessing it through Shuttle provides an upgrade path to multi-PSP operations without disrupting existing merchant relationships. Shuttle can continue routing US transactions to Fortis, preserving the platform’s revenue-share arrangement and merchant portfolio, while adding connections to international processors for cross-border payments or to alternative PSPs for redundancy. This approach lets platforms grow beyond a single-processor model at their own pace, expanding their payment capabilities without renegotiating contracts or migrating merchants away from Fortis.
