Invoice Ninja

Invoice Ninja is a fully open-source invoicing and billing platform trusted by over 100,000 businesses globally. Designed for freelancers, consultants, and small businesses, it covers the complete billing workflow — from time tracking and quote creation through invoicing, payment collection, and expense reporting — in a single self-hosted application. Built on Laravel, Invoice Ninja delivers enterprise-grade invoicing features without recurring subscription fees or per-transaction costs.

Why deploy Invoice Ninja on Hostinger VPS

Hosting Invoice Ninja on your own VPS puts your financial data entirely under your control. Unlike SaaS invoicing tools that charge monthly fees or take a percentage of transactions, a self-hosted instance eliminates recurring software costs and third-party access to sensitive client and payment data. Hostinger VPS provides the dedicated resources Invoice Ninja needs for PDF generation (using the bundled Chromium renderer), background queue processing, and responsive client portal performance — all scalable as your client base and invoice volume grow.
