I need the full Laravel Billing package wired into my existing SaaS application. The project already has a solid authentication layer, so you can focus strictly on the payment flow. I’m running the current Laravel version and want to keep everything as clean and native as possible, following the docs at https://laravel.com/docs/13.x/billing. Your job is to pull the package in, configure the providers (Stripe is the default but keep the code abstract so I can swap gateways later), set up the database tables and webhooks, and surface a simple, reusable UI stub I can drop into my blade files. Whether you prefer Cashier’s built-in components or an API-only approach is up to you as long as customers can complete one-off charges and move seamlessly into recurring plans with optional coupon support when I decide to switch those on. Acceptance will be straightforward: • migrations run without errors, • test transactions succeed in Stripe’s sandbox, • subscription status, invoices, refunds, and webhook events are recorded in my dashboards, • and all code is clearly commented so I can extend it later. If something in the flow is unclear, flag it early—I’d rather refine the spec than refactor twice.
