Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
Cotizaciones, facturas, pagos, gastos y un portal dentro de un ERP mucho más grande de lo que nadie pidió.
licenseGPL-3.0
runsyour machine or their cloud
installManaged Frappe Cloud signup, or the supported Frappe Docker/Bench deployment
dataSelf-hosted companies live in MariaDB site databases with site files and attachments on the server; managed-hosting data lives in the selected Frappe Cloud site.
the catch vs Invoice NinjaERPNext can issue and collect invoices but its much larger ERP interface is less polished for client portals, payment gateways, recurring billing, and solo-business onboarding.
setupSelf-hosting is an ERP deployment rather than a desktop install: Docker or Bench, MariaDB, Redis, workers, a reverse proxy, backups, upgrades, and country-specific accounting setup.

Facturas, presupuestos, gastos, pagos y portal de clientes; la factura llega en forma de mantenimiento de Docker.
licenseAGPL-3.0
runsyour server
installDeploy a stable tagged release with the official Docker Compose example
dataInvoices, estimates, customers, expenses, payments, and settings live in the configured application database, SQLite is available for a small install, with uploaded files in persistent server storage.
the catch vs Invoice NinjaInvoiceShelf has a smaller payment-gateway, mobile-app, integration, recurring-billing, and support ecosystem than Invoice Ninja, with a less mature current release line.
setupThe first obstacle is choosing a stable 2.x release rather than the default next/3.x alpha branch, then operating Docker, persistent storage, mail, HTTPS, backups, and upgrades.

La misma pila de facturación en tu propio servidor; la facturación es gratis, la licencia es de código disponible y quitar su marca cuesta extra.
licenseElastic-2.0
runsyour server
installOfficial Docker Compose/INmanage path, or a PHP web-server installation with a MySQL-compatible database
dataClients, invoices, quotes, expenses, payments, and settings live in the deployment's MySQL-compatible database; uploaded documents and generated files live under the persistent storage directory, and APP_KEY protects selected secrets.
the catch vs Invoice NinjaThe application is familiar, but the free self-hosted edition transfers uptime, security, mail delivery, backups, upgrades, and branding removal from Invoice Ninja's service to the user.
setupThe free path requires PHP or Docker, MySQL, cron and queue workers, TLS, mail, backups, upgrades, and accepting Invoice Ninja branding unless a separate white-label license is purchased.

the catch vs Invoice NinjaZoho Invoice is easier to adopt but the free service caps annual invoices, users, and projects and retains Zoho branding, making it less flexible than a paid Invoice Ninja account.

They pay because billing software is boring and should not break on invoice day. If none of that applies to you, any pick above saves $168 a year.
Is there a free alternative to Invoice Ninja?
Yes: ERPNext, InvoiceShelf, Invoice Ninja self-hosted and 1 more. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Invoice Ninja?
Our verdict is SÍ. 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. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/invoice-ninja.
