Payments · Vertical software

One payments platform for UK specialist software.

VerticalStack is building one payments platform for software businesses that serve a single trade. They license it, their customers’ card payments run through it, and the payments that already flow through their software become a source of revenue for the software business, not only for the processor.

The platform

Payments built for the software that runs a trade.

Specialist software sits at the centre of how thousands of small businesses run, yet the card payments flowing through it usually earn their money for a processor. VerticalStack is building one payments platform, with FCA authorisation in progress, so that revenue can stay with the software.

Build

Onboarding, KYC and KYB, underwriting, settlement and reconciliation are built once and run for every software partner on the platform.

License

Software businesses license the platform. Their customers’ card payments run through it from day one, on established partner infrastructure while our own regulated core is built.

Grow

Where it suits the founder, we also buy software businesses, or back them to keep building. The product, the brand and the team carry on.

Where to start

Two ways in.

Choose the path that fits you. Both lead to a direct conversation with the founders.
