Zaisub – Laravel Subscriptions, Recurring Billing, Proration, Coupons, Taxes/VAT, Invoices & Dunning (GPL)

🚀 Overview

Zaisub is a production-focused subscription & billing management script for Laravel apps. Define products and plans, manage trials, handle upgrades/downgrades with proration, collect payments through multiple gateways, and automate taxes, invoices, and dunning workflows. With a clean admin panel and developer-friendly webhooks, Zaisub fits SaaS, membership sites, APIs, digital goods, and course platforms.

Experience (real-world relevance): Modeled on patterns used by modern SaaS products—seat-based pricing, usage add-ons, failed-payment recovery, tax compliance prompts, and self-serve portals that reduce support load.
