Invoice Management

Organizations need modern, secure invoice management solutions that work globally with high reliability. Traditional invoice systems often lack multi-tenant isolation, professional PDF capabilities, role-based access control, and global edge deployment. Companies require platforms that scale automatically, maintain data privacy, provide professional client-facing documents, and deliver real-time analytics — all while being accessible from anywhere with optimal performance.

Key technical challenges included implementing React Server Components for optimal loading, multi-tenant data isolation at the database level, professional PDF generation at scale, and defense-in-depth security across edge, application, and database layers.

Built a modern serverless SaaS platform using Next.js 15 App Router with React 19 Server Components, deployed to Cloudflare Pages/Workers for global edge distribution. Supabase PostgreSQL with Row-Level Security provides database-level multi-tenant isolation. Professional PDF pipeline combines Puppeteer for server-side generation with Syncfusion for in-browser viewing.

The platform features four-role RBAC (Owner, Admin, Member, Viewer), full invoice CRUD with automated VAT calculations, six analytical report pages with 8 Recharts visualizations, multi-level caching (CDN, Upstash Redis, database), Google OAuth authentication, and defense-in-depth security across edge, application, and database layers.

The platform achieves global deployment across 275+ Cloudflare data centers with serverless auto-scaling. Complete multi-tenant data isolation via PostgreSQL RLS ensures security. Six report pages with 8 chart visualizations cover revenue, VAT, outstanding invoices, and client performance. The Apple-inspired design system uses an 8-point grid with shadcn/ui components. Built with Next.js 15, React 19, and Cloudflare edge.
