What we verified

Invoice Ninja currently publishes a free plan for up to five clients with unlimited invoicing, and Ninja Pro at $14 per month. The vendor documents recurring invoices, auto-billing, deposits, partial payments, quotes and proposals, a client portal, expense tracking, projects, time tracking, product and inventory management, and multiple payment gateways.

Where Invoice Ninja stands out

• Free starting point: the free plan includes recurring invoicing, payment gateways, projects, billable time tracking, expenses, and a client portal.
• Project-to-invoice flow: time and project tasks can be converted into invoice line items.
• Client portal: clients can view invoices, quotes, payment history, documents, and payment methods.
• Quotes and proposals: client approvals can convert into invoices.

Important limitations

The free plan is capped at five clients, and users who want a stripped-down billing-only experience may find the broader feature set more than they need. The product is feature-rich, so onboarding and configuration deserve a real trial with your own workflow.
