We built PBX.IM's cloud phone system from scratch - a full SaaS platform using Laravel and React. The result: 750 clients in under a year, organic-first growth with zero paid acquisition, and a product that handles VoIP, billing, and Teams integration at scale.
750+
Clients onboarded in 11 months with zero paid acquisition
PBX.IM came to us with a clear ambition: make advanced VoIP tools accessible, scalable, and genuinely useful for small and mid-sized businesses. The cloud phone market was crowded with legacy systems that were either dated, painfully complex, or priced for enterprise — leaving SMBs stuck between bad options.
The product had to feel effortless for non-technical operators while still supporting auto attendants, call queues, real-time monitoring, role-based access, and HD-quality calling at scale. On top of that, the business needed billing, third-party integrations (Stripe, Twilio, SendGrid, Microsoft Teams), encrypted communication, and a CI/CD pipeline that could ship without breaking trust.
BinarCode owned the full build end-to-end: product design, frontend and backend engineering, integrations, deployment infrastructure, and the brand positioning and marketing site that turned PBX.IM's story into demand.
Over roughly a year of constant iteration and shared ownership, we worked through four overlapping phases — turning a product brief into a live SaaS that handles VoIP, billing, and integrations for hundreds of paying customers.
Phase 2
The frontend was built with React and Next.js for speed, SEO, and snappy app-shell transitions. The backend ran on Laravel and PHP for secure, well-structured business logic — handling user management, number provisioning, billing, and the call routing layer. MySQL powered persistent data and Redis kept hot paths fast.

Phase 4
Frontend deployed through Vercel, backend through Laravel Forge, with an automated CI/CD pipeline that gated every release behind tests and review. We layered in encrypted communication, role-based access controls, and 99.99% uptime targets so the platform stayed trustworthy as customer volume grew.
Infrastructure · DevOps
Phase 1
We started by mapping every flow a non-technical operator would touch — provisioning numbers, configuring call queues, managing users, reading call analytics. From there we built a clean, modern design system with custom UI components that minimized friction at every step. The goal was a product an SMB owner could set up themselves in an afternoon.

Phase 3
We wired in the services that turned the platform into a real business: Stripe for subscriptions and metered billing, Twilio for SMS, SendGrid for transactional email, and a native Microsoft Teams integration so existing Teams users could route calls through PBX.IM without changing tools. Every integration was wrapped with retry rules, error handling, and audit logging.
Payments & Comms · Integration Layer
We took PBX.IM from a product brief to a live SaaS without a single in-house engineer on their side. Design, frontend, backend, integrations, deployment, brand and marketing site — all of it sat with our team. They focused on customers and sales while we shipped the product.
Eleven months after launch the platform had crossed 750 paying clients on entirely organic growth — no paid acquisition. The product, the positioning, and the marketing site did the lifting together, which is exactly the partnership shape we set out to build.
We paired React/Next.js on the frontend with Laravel on the backend so the app could ship fast without compromising on security, billing accuracy, or call-routing reliability.

Stripe-powered subscription management with metered usage, invoicing, and self-serve plan changes for every customer.
Positioning, landing page copy, and benefit-driven content that drove 750+ clients in 11 months without paid ads.
In its first 11 months PBX.IM grew from zero to 750+ paying clients without spending a dollar on paid acquisition — the product, brand and marketing site compounded together. The platform held a 99.99% uptime target with encrypted communication and role-based access throughout, and the native Microsoft Teams integration unlocked customers who would never have switched tools otherwise. Today the partnership continues: we keep shipping, integrating, and scaling the platform alongside the PBX.IM team.
