Can I vibecode Invoice Ninja?
// one session, and a personal version you can actually use
Invoice Ninja is open source, so the hosted subscription can be replaced by self-hosting if you can handle ops, updates, payment config, and backups.
confidence: high
what it is: Invoicing, quotes, payments, expenses, and client portal software

Gioco editoriale: il verdetto dice se un agente può, l’indice se conviene.

The prompt
One session with a coding agent and your version runs.
Build me a small invoicing app to replace hosted Invoice Ninja. Requirements:
- Note in the README that Invoice Ninja itself is open source and self-hostable;
this build is the lighter option for someone who needs invoices, not a platform.
- Node + Express + better-sqlite3, admin UI on localhost:4840, server-rendered pages.
- Clients (name, email, address, currency, default rate) and invoices with line items
(description, qty, unit price, tax %), auto-numbered INV-2026-001 style.
- Generate a clean PDF per invoice with puppeteer from an HTML template: my logo,
payment terms, and bank details read from a config file.
- Email the PDF to the client via SMTP (creds in .env); track draft/sent/paid status
and show a dashboard of unpaid invoices with days outstanding.
- Optional Stripe payment link per invoice (key in .env), included in the PDF and
the email. I mark invoices paid by hand when money lands.
- Nightly backup: copy the SQLite file to backups/YYYY-MM-DD.db, keep 30.
- Binds to localhost, no client portal, no accounts, no telemetry.
- Out of scope: quotes, expenses, multi-user, and automatic payment reconciliation.
- README: .env keys, how to edit the invoice template, and the numbering rule.Prompt generated from the data on this page, not reviewed by hand yet. In English on purpose — it is the language coding agents work best in.
What you lose
- managed hosting
- upgrades
- backups
- support
- payment setup convenience
- reduced ops risk
Why people still pay
They pay because billing software is boring and should not break on invoice day.

Free alternatives
Not in the mood to build it? These already exist, they are free or open source, and we checked them one by one.
Rejected (3) — and why
- Crater (si apre in una nuova scheda) — Still widely recommended; last push August 2024 and the last release is four years old.
- InvoicePlane (si apre in una nuova scheda) — Quotes, invoices and payments are solid; expenses and a real client portal never show up.
- SolidInvoice (si apre in una nuova scheda) — Quotes, recurring invoices and payments are here; expense tracking and a client portal are not.
Who has already built it
Starting from here is still vibecoding: the prompt is for when you want it exactly your way.
- Invoice Ninja (opens in a new tab) — The product's own open-source invoicing platform. (alive)
