/ Project Overview

Democratizing Financial Services for Small Businesses

The 24/7 Billing platform was engineered to democratize financial services for small businesses and sole traders. Axiom developed a full-cycle ecosystem—including web and mobile applications—that transforms any smartphone into a secure, portable Point-of-Sale (POS) terminal.

Our focus was on creating a transparent, friction-less payment flow that bypasses the rigid barriers of traditional banking.

Compliance & Complex Orchestration

The primary engineering challenge was building a system that complies with stringent financial regulations of various jurisdictions while maintaining a simple user experience.

Stripe Orchestration

Complex webhooks and controller layers for automated payouts, refunds, and real-time data sync

KYC & Verification

Rigorous Know Your Customer process required by Stripe and financial regulators

Global Compliance

Meeting legal requirements across jurisdictions without limiting speed-of-payment

Stripe Webhook Orchestration

Advanced Server-Side Logic

Not just a "payment button" — deep server-side orchestration for enterprise-grade reliability.

How We Built It

Advanced Stripe Gateway Integration

We engineered a custom "Shell" architecture around the Stripe API. Our backend team developed a sophisticated controller layer to handle asynchronous events (webhooks) such as payment updates, automated payout generation, and complex payback logic.

Hybrid Mobile Performance (React Native)

To ensure speed-to-market without sacrificing quality, we utilized React Native. We integrated native modules for Touch ID / Face ID and CameraX to allow users to scan physical cards, instantly populating payment data with high accuracy.

Robust Backend Architecture (Laravel & Docker)

Using an MVC structure, we built a scalable backend designed for future functional expansion. The entire environment was containerized using Docker, ensuring consistency across development, staging, and production.

Multi-Factor Security (2FA)

To protect every transaction, we implemented a custom Two-Factor Authentication system using SMS and QR-code verification, providing an extra layer of defense against unauthorized access.
