Scaling a B2B FinTech Platform to Process £12M Monthly

We modernised a legacy PHP monolith into a scalable Laravel SaaS with Stripe billing, multi-tenant workspaces, and automated KYC flows.

The challenge

Founders ran on a legacy PHP codebase with no API layer, manual billing reconciliation, and security gaps blocking enterprise sales. They needed a production SaaS in under two months without hiring an in-house team.

Our solution

CSNexa delivered a greenfield Laravel + Vue.js platform with Stripe subscriptions, role-based teams, audit logging, and a documented REST API. We ran two-week sprints with weekly demos and migrated historical customer data with validation scripts.
