The software layer that turns
a terminal into an EPOS.
Flint sits between the payment terminal and the payment application — enabling Payment Service Providers to offer a differentiated, white-label merchant experience without building it themselves.
The opportunity
Payment terminals are commoditised. PSPs compete on price and lose merchants to platforms that offer more. Flint changes that — a software layer the PSP deploys to deliver a differentiated merchant experience on top of their existing terminal estate.
The intelligent layer
Flint is the software layer that enhances a standard payment app. PSPs deploy Flint on top of their terminal estate to deliver a full merchant management experience — without building or maintaining it.
Revenue uplift & retention
Differentiate beyond the terminal. Merchants stay for the tools — split bills, pay-by-link, vouchers, online orders, reporting — reducing churn and increasing lifetime value.
Deploy in days, not months
No development roadmap required. Flint runs on standard Android terminals and browsers. A PSP can go from signed agreement to live merchants on the same day.
Offline-first resilience
Flint keeps trading through connectivity outages. Sales, receipts, and kitchen routing all continue offline and sync on reconnect — a critical differentiator in hospitality.
The three tiers
Every tier can be white-labelled. Distributors sell the tier that fits the PSP's merchant base — and upsell as they grow.
Flint Lite
Payments-plus layer
Everything in Standard except product catalogue. For PSPs who want to enhance the terminal experience without a full POS.
Flint Standard
Connected merchant
Full product catalogue, online orders, and all the payment-enhancement tools. The complete entry-level merchant platform.
Flint Pro
Full EPOS
Tables, tabs, order routing, memberships, stock, and AI. The complete hospitality management suite.

White-label & support
All tiers are eligible for white-labelling. Distributors own the support relationship, keeping the PSP's overhead low while every merchant always has someone to call.
White-label pathways
Every tier — Lite, Standard, and Pro — can be white-labeled. Two routes to unlock:
Annual minimum software spend
Partners who commit to a defined annual software volume qualify for white-label deployment automatically — branding, custom domain, and a unified merchant experience.
Statement of Work
For bespoke deployments or custom integration requirements, a tailored SOW unlocks white-label with project-scoped deliverables and timelines.
The support model
The distributor is the support backbone — keeping the PSP's overhead low while merchants always have someone to call.
Core platform engineering, security patches, OTA updates, and escalations.
Merchant onboarding, configuration, day-to-day support, and relationship management.
Merchant relationship, terminal deployment, and first-line queries.
