Build a Subscription Billing Platform with AI - in Hours
ProjectCode generates a complete, production-ready Subscription Billing Platform from a single natural language prompt. In hours instead of months, you get a React frontend, NestJS REST API, PostgreSQL database, and authentication - fully integrated, live-previewed, and deployed to a URL you own.

The Challenge
Why building a Subscription Billing from scratch is hard
Building a Subscription Billing Platform from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing subscription billing-specific business logic, integrations, and role-based access rules.
What's Included
Everything your Subscription Billing needs
ProjectCode generates a production-ready Subscription Billing with all the modules your team needs from day one.
Architecture
How it's built
The generated Subscription Billing follows production-grade architecture patterns.
React 18 + TypeScript frontend with role-based dashboards tailored for subscription billing workflows
NestJS REST API with dedicated subscription billing modules, DTOs, validators, and service layer
PostgreSQL relational schema with normalized tables for all subscription billing entities
JWT + Google OAuth authentication with granular permission gates per role
Real-time Socket.IO events for live subscription billing status updates and notifications
Managed hosting with one-click deploy, custom domain, and auto-SSL
Database
PostgreSQL schema designed for Subscription Billing
ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.
- plans (id, name, interval, price, currency, features jsonb, trial_days, is_active, workspace_id)
- subscriptions (id, customer_id, plan_id, status, current_period_start, current_period_end, trial_end, cancel_at, canceled_at, payment_method_id)
- invoices (id, subscription_id, customer_id, status, period_start, period_end, subtotal, tax, total, paid_at, hosted_invoice_url)
- usage_records (id, subscription_id, metric, quantity, timestamp, idempotency_key)

FAQ
Common questions about building a Subscription Billing
Your product reports usage events to the billing platform API (e.g., 1,000 API calls on Jan 15). At the end of the billing period, usage is summed and compared against the plan's included usage. Overage units are billed at the metered rate on the next invoice.
