Can I vibe code Invoice Ninja?
Open-source invoicing with quotes, payments, and a client portal.
An invoice is structured data rendered to a PDF with a payment link attached — squarely vibe-codeable. An agent will build clients, line items, tax math, sequential numbering, and Stripe payment links in a weekend, and the result matches how you actually bill instead of the other way around. Invoice Ninja is also open source, so self-hosting the full product is a legitimate shortcut if you want recurring billing and a client portal. The hosted fee mostly buys someone else keeping billing boring on invoice day.
Build a personal invoicing tool to replace hosted Invoice Ninja. Clients table plus invoices with line items, quantity, unit price, tax rate, and automatic sequential numbering like INV-2026-014. Render invoices as clean branded PDFs from an HTML template, email them via Resend with a Stripe Payment Link attached, and mark them paid automatically from the Stripe webhook. Dashboard shows outstanding, overdue, and paid totals by month, with CSV export for my accountant. Include a public /invoice/[id] page clients can view and pay from. Next.js App Router, Postgres with Prisma, Puppeteer for PDF rendering, deployed on Vercel.
An invoice generator with clients, line items, and tax that renders branded PDFs, emails them with a Stripe payment link, and tracks paid and overdue.
- Managed hosting with upgrades and backups handled for you on invoice day
- Recurring invoices, quotes, and auto-billing workflows out of the box
- The client portal where customers view their history and pay without emailing you
- Dozens of prebuilt payment-gateway integrations beyond your one Stripe link
Billing is the one system that must not break, so paying someone to host, upgrade, and back it up is cheap insurance.
A prompt is the first move, not the whole game. Course 01 teaches you to take a prompt like this one to a shipped, working app — reviewing, correcting, and steering the agent the whole way.
