US LLC Services Platform

Project Summary

A comprehensive, full-stack web application designed to streamline the US LLC formation process for non-resident entrepreneurs, particularly from the German-speaking (DACH) region. The platform serves as a one-stop-shop, guiding users from initial inquiry and cost calculation through the entire legal formation process, payment, and post-formation management via a secure user dashboard.

The Challenge

Forming a US-based company as a non-resident is often a complex, opaque, and expensive process. Entrepreneurs face challenges with legal requirements, document handling, payment processing, and obtaining essential services like a US business address, tax ID (EIN), and phone number. This project aimed to solve that by creating a user-friendly, automated, and transparent digital platform.

The Solution

I developed a robust, multi-faceted application that handles the entire customer lifecycle. The platform is divided into a public-facing marketing and information site, a user-centric onboarding wizard, and a powerful dual-purpose dashboard for both customers and administrators.

Key Features Implemented

• Intuitive Onboarding Wizard: A multi-step form (built with React Hook Form, Zod, and Zustand) that intelligently collects all necessary data for the LLC formation, including founder details, company structure, and service add-ons.
• Dynamic Price Calculation: A real-time price summary component that updates as the user selects services and add-ons during onboarding.
• Secure Payment Integration: Seamless and secure checkout process powered by Stripe, handling one-time payments for formations and recurring subscriptions for services like US phone numbers.
• Authenticated User Dashboard: A secure portal where customers can track status, download documents, purchase additional services, manage their US phone number and domains, and participate in an affiliate program.
• Comprehensive Admin Dashboard: A separate, role-protected interface for administrators to manage orders, add internal notes, generate data for IRS forms, manage the affiliate program, and send newsletters.
• Serverless Backend & API Integrations: Powered by Supabase Edge Functions (Deno/TypeScript) handling all backend logic and third-party integrations with Stripe, Twilio, Resend, and Porkbun.
