Invoice Ninja review

Invoice Ninja combines invoicing, online payments, recurring billing, expense tracking, billable time and project tools for freelancers and small businesses. You can create invoices with one of 11 templates, add your logo and brand colors, and let clients pay through supported gateways including Stripe, PayPal, Square and GoCardless. The product also offers a client portal for invoices and documents, plus project features such as task tracking and Kanban boards.

There is a free plan, but it is limited to five clients. It includes unlimited invoicing, online payments and recurring invoices. Ninja Pro removes the client cap and costs $14 per month, or $140 upfront for a year ($11.67 per month equivalent), according to the pricing details checked November 6, 2026. Invoice Ninja is best understood as billing software with adjacent project tools, not a full accounting or operations suite.

Invoice Ninja’s clearest value is getting invoices out and payments in without paying for a large business suite. The free plan includes unlimited invoices, 11 templates, online payments and recurring invoices, but caps you at five clients. For more clients, Ninja Pro costs $14 month to month or $140 per year, paid upfront. The pricing page lists unlimited clients and invoices, REST API access and priority direct support on Pro.

• Recurring invoices and automated billing cycles suit businesses that bill clients on a schedule. One agency owner on Reddit says auto-billing reduced its accounts receivable.
• Supported payment gateways include Stripe, PayPal, Square and GoCardless, so clients can pay online rather than sending payment separately.
• The API gives businesses a route to connect Invoice Ninja with other software; a Reddit commenter also praised it, though that is user feedback, not a guarantee about a specific integration.
• The product adds expenses, billable-time tracking and projects without charging for those features as a separate product, according to the published feature list.

That is a useful mix for a small service business whose main job is creating estimates or invoices and collecting payment.

The project and time tools are less convincing than the billing. Invoice Ninja lists project tracking, tasks, Kanban boards and billable time, but a small-business Reddit thread describes friction around project numbers, task categories and reporting. Other commenters say the product is strongest when you already know what you sold and need to invoice it; one says it is not an inventory system. Treat those as user experiences, but they point to a real buying question: do you need billing support, or a system to run jobs and track work in detail?

The free plan’s five-client cap is a hard limit for a growing client list. Ninja Pro is $14 monthly or $140 annually; Enterprise starts at $18 per month for one or two users, is tiered up to $300 per month for 51–100 users, and supports up to 100 account users. It includes 250 PEPPOL credits. Premium Business starts at $280 per year and adds developer concierge, priority support and migration assistance. Those higher tiers make less sense if you only need basic invoice PDFs and payment tracking.

Invoice Ninja has a free plan for up to 5 clients, with unlimited invoicing, 11 templates, online payments and recurring invoices. Ninja Pro costs $14 per month, or $140 per year paid upfront ($11.67 per month). That is the first big jump: the main additions are unlimited clients, REST API access and priority direct support.

Enterprise starts at $18 per month for 1–2 users and scales by user count, up to $300 per month for 51–100 users. It includes up to 100 account users and 250 PEPPOL credits. Premium Business is listed from $280 per year ($23.33 per month equivalent), with developer concierge, priority support and data migration assistance; a monthly price is not published.

The pricing page lists no add-ons. Annual billing is paid upfront and includes two months free; Pro’s $11.67 figure is an equivalent monthly rate, not a monthly payment. Check the Enterprise user tier and Premium’s annual-only price against your team’s needs before switching.

The published product and pricing information does not specify migration tools, supported import formats, export options or how long a move takes. Treat those as unanswered questions, not assumed features: confirm you can move clients, invoices, payment records, expenses and time entries in a usable format before relying on Invoice Ninja as your system of record.

Premium Business includes data migration assistance from $280 per year, but the scope of that help is not published. The sources also do not document cancellation, data retention or account lock-in terms. We were not given Reddit posts or comments for this review, so we can’t responsibly say what users report as reasons for leaving. Before committing, ask support for an export sample and migration scope, and check that your payment gateways and recurring billing setup can be carried over. The free plan’s five-client cap is another likely trigger to compare plans if your client list grows.
