No referral code or link is currently available for Invoice Ninja.
Quick Summary
Invoice Ninja is invoicing and basic billing software available both as a hosted SaaS product and as a self-hosted open-source application, which makes it a particularly common choice for freelancers, developers, and small agencies who want to avoid recurring per-invoice or per-client SaaS fees entirely by running it on their own server. Its open-source codebase also means no vendor lock-in — the software keeps working even if the company behind it changed direction or shut down, a real consideration for invoicing tools handling ongoing client billing relationships.

Pros
- Free if self-hosted, with no client or invoice limits, since there's no per-usage SaaS pricing model at all in that configuration
- Open-source codebase means no vendor lock-in — the software keeps functioning even if the company changes direction or the hosted service is discontinued
- Recurring invoices and basic billing automation are included even at the lower-priced hosted tier
- Full source code transparency appeals to developers and technically-minded freelancers who want to understand or customize exactly how their billing software works
- Mobile apps cover core invoicing tasks for freelancers who need to send or check invoices away from a computer
Cons
- Self-hosting requires real technical setup (server provisioning, maintenance, updates) that most non-developers won't want to take on themselves
- Hosted version's interface is less polished and modern than dedicated SaaS competitors like FreshBooks or Wave
- Self-hosted users are responsible for their own backups, security patching, and uptime, unlike a managed SaaS product
- Smaller, less mainstream user base than FreshBooks means fewer third-party tutorials and community troubleshooting resources
Invoice Ninja Pricing Plans

Invoice Ninja’s core appeal rests on a choice most invoicing tools don’t offer: the option to self-host the entire application for free, with no per-invoice or per-client limits, rather than being locked into an ongoing SaaS subscription regardless of how light your actual billing volume is.
Free, Unlimited Self-Hosting
For freelancers, developers, and small agencies comfortable with basic server management, self-hosting Invoice Ninja eliminates recurring software costs entirely — there’s no per-invoice fee, no client cap, and no monthly subscription, since you’re running the open-source application on infrastructure you control. For technically capable users with modest budgets, this can mean genuinely free invoicing indefinitely, a meaningfully different value proposition than even generous free tiers on SaaS competitors.
No Vendor Lock-In
Because Invoice Ninja is open-source, self-hosted users aren’t dependent on the company’s continued existence or business decisions to keep using the software — the code remains usable (and even modifiable) regardless of what happens to the company behind it. For a tool handling ongoing client billing relationships and financial records, this independence from a single vendor’s fate is a real, if often underappreciated, form of risk reduction.
The Hosted Alternative
For users who want Invoice Ninja’s functionality without taking on server management themselves, the hosted Pro and Enterprise tiers work like a standard SaaS product — Invoice Ninja manages the infrastructure, and users pay a straightforward monthly fee. This removes the self-hosting technical burden while still benefiting from the underlying open-source software’s transparency.
The Technical Setup Tradeoff
The free self-hosting option’s main practical limitation is exactly what makes it valuable: it requires real technical comfort with server provisioning, security configuration, ongoing maintenance, and backups. For non-technical freelancers, this isn’t a realistic path, and the choice effectively becomes either developing that technical comfort or simply paying for the hosted tier (at which point the cost-comparison advantage over competitors like FreshBooks narrows considerably).
Pricing
| Plan | Price | What’s included |
|---|---|---|
| Free (self-hosted) | $0 | Unlimited invoices, your own server |
| Pro | $10/month | Hosted version, recurring invoices |
| Enterprise | $14/month | Multiple users, more storage |
Who Should Use Invoice Ninja
Technically comfortable freelancers and developers wanting to eliminate recurring SaaS costs get genuine value from free self-hosting. Users who specifically value open-source software and avoiding vendor lock-in for financial tools find real appeal in its transparency and independence. Non-technical freelancers wanting a polished, fully managed experience without any server management are likely better served by FreshBooks or Wave.
Verdict
Invoice Ninja’s self-hosted free tier is a genuinely distinctive option in the invoicing software category, offering real cost and independence advantages for technically capable users willing to manage their own infrastructure. For users without that technical comfort, the hosted version remains a reasonable but less differentiated choice against more polished dedicated SaaS competitors.

Frequently Asked Questions
Common questions about Invoice Ninja, answered by our editorial team.
- Is Invoice Ninja free?
- Yes, genuinely free with unlimited invoices and clients if self-hosted on your own server. The hosted (managed) version starts at $10/month for Pro, scaling to $14/month for Enterprise with multiple users.
- Do I need technical skills to use Invoice Ninja?
- Only if self-hosting — running your own instance requires setting up a server, which takes real technical comfort. The hosted Pro/Enterprise plans work like any standard SaaS product, requiring no technical setup beyond signing up.
- Is Invoice Ninja good for freelancers?
- Yes, particularly freelancers and developers comfortable with self-hosting who want to avoid recurring SaaS fees entirely, or those who specifically value open-source software and avoiding vendor lock-in for their billing tool.
- What does open-source mean for Invoice Ninja users?
- It means the full source code is publicly available, so the software isn't dependent on one company's continued existence to keep functioning — even if the company behind Invoice Ninja shut down, self-hosted users could continue running and even modifying their existing installation.
- Is the hosted version of Invoice Ninja as polished as FreshBooks?
- Generally not — the hosted version's interface is functional but less refined and modern than dedicated SaaS competitors like FreshBooks or Wave, which have invested more heavily in UX design specifically.
- What's the difference between self-hosted and hosted Invoice Ninja?
- Self-hosted means running the software on your own server, free with no usage limits but requiring you to handle setup, security, and maintenance yourself. Hosted means Invoice Ninja runs and maintains the infrastructure for you on a paid subscription, similar to any standard SaaS billing tool.
- Does Invoice Ninja support recurring invoices?
- Yes, recurring invoice automation is included even on the lower-priced Pro hosted tier, letting freelancers and small businesses automate regular billing for ongoing client relationships without manually creating each invoice.
- What is a referral bonus on Kreemhunt?
- A referral bonus is an incentive — like bonus credit, a discount, or extra features — that a software vendor offers when someone signs up through a referral link or code instead of going to the product directly. Kreemhunt tracks which of the tools we cover currently have an active referral arrangement, like Invoice Ninja, so you don't have to hunt for one yourself.
- Does Invoice Ninja currently have a referral code or link?
- Not at the moment. Kreemhunt doesn't have a tracked referral code or link for Invoice Ninja right now — this page will update automatically if one becomes available, so it's worth checking back before you sign up.
- Does using a referral link cost me anything extra?
- No. Using a referral link or code to sign up for Invoice Ninja costs the same as signing up directly — in most cases referral programs are designed so the new user gets a bonus and the referrer gets a reward, with no markup passed on to you.
- How do I claim Invoice Ninja's referral bonus?
- There's no active referral bonus for Invoice Ninja tracked on Kreemhunt right now. Once one becomes available, it'll appear in the referral box on this page along with instructions for claiming it.
