Paidly — Invoice Generator

Paidly is a production-ready invoice generator and SaaS starter built on **Next.js 16 (App Router)**, **TypeScript**, **Prisma 7** and **Stripe** — a complete enterprise invoicing product out of the box. Manage clients, emit gap-free invoices with tax-inclusive/exclusive VAT & GST, chase overdue balances with automated dunning, automate recurring invoicing, collect via Stripe "pay now" links, let clients pay through a token-gated public portal, and integrate with anything through a signed REST API with HMAC webhooks. It also includes everything a real SaaS needs beyond the product surface: email/password **and** Google OAuth (Auth.js v5), multi-tenant **organizations** with role-based permissions, FREE/PRO/TEAM **plan entitlements** via Stripe, branded transactional email (Resend + react-email), an **admin support & moderation panel**, audit logging, a self-serve REST API panel, analytics dashboards, and CSV reports. Everything is scoped to a **workspace** (your personal account or an organization), and money is handled as **integer minor units with BigInt half-up rounding** end-to-end — no float drift.
