A broad invoicing platform with a useful free tier and flexible deployment options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Invoice Ninja is invoicing and payment software for freelancers, contractors, tradespeople, agencies, and small-to-medium businesses. It creates and sends invoices and quotes, supports online payments through connected gateways, and provides recurring billing, direct payment links, client portals, billable time tracking, project management, expense management, and reporting. The hosted product is available on web, Windows, macOS, Linux, iOS, and Android, with synchronized data across mobile and desktop apps. A self-hosted edition is also offered as source-available software under the Elastic License v2.
The Free plan is a practical starting point for smaller operations, with 5 clients, unlimited invoicing, online payments, recurring invoices, and a client portal. Ninja Pro expands the service with unlimited clients and invoices, 11 invoice templates, API integration, automatic late-payment reminders, and reports. Enterprise plans are organized by user capacity, from 2 users through 30 users, and add additional account users, user permissions, a branded portal, bank account sync, e-Invoicing, and PEPPOL. The published plans show a clear progression from core billing to automation, reporting, and multi-user administration.
Platform coverage and workflow connectivity are central strengths. Invoice Ninja supports REST API access and integrations with Zapier, Make, n8n, Pabbly, and Integrately, while connected payment gateways support online collection. Its combination of quotes, payment requests, recurring invoices, time tracking, projects, expenses, and portals suits teams that want more than basic invoice creation. Smaller contractors should consider the Free plan if 5 clients is sufficient; growing teams are better matched to Ninja Pro, while organizations needing permissions, branded portals, bank synchronization, or PEPPOL should look to Enterprise.
