qBilling — Multi-Tenant SaaS CRM, Billing & Enterprise Working System
qBilling has grown far past an invoicing script. It’s now a full CRM-centered enterprise working system: Lead → Contact/Firm → Deal → Challenge → Timesheet → Bill → Cost → Renewal, in a single related app. It ships in two industrial modes from the identical codebase, with no code fork required:
- Mode A — Self-Hosted Core (CodeCanyon): one lively enterprise, put in by yourself server by way of a guided net installer.
- Mode B — SaaS Platform: limitless tenants on one set up, with a devoted Platform Admin console for packages, billing, and tenant lifecycle — launch your personal “qBilling-as-a-Service” enterprise.
Constructed on Laravel 13 + PHP 8.4, with your complete UI rebuilt on Inertia.js v3 + React 19 and the Tabler design system.
