11:100 – Invoice Ninja : The Free Invoicing Powerhouse

Invoice Ninja – The game-changer, indeed.

Let’s be honest—few things drain a founder’s energy like managing invoices.

You want to focus on clients, growth, product, your next big idea… not chasing payments or fixing messy billing spreadsheets. And yet, invoicing is one thing you absolutely cannot afford to get wrong.

If you’ve ever thought:

• “I wish invoicing didn’t take up so much time.”
• “Why are premium invoicing tools so expensive?”
• “I need something simple, secure, and professional—without another subscription.”

Then Invoice Ninja is that breath of fresh air you’ve been waiting for.

It’s free.
It’s open source.
It’s powerful.
And it’s trusted by thousands of freelancers, small businesses, and scaling startups.

Let’s dive into what makes Invoice Ninja such a game-changer.

What Is Invoice Ninja?

Invoice Ninja is a free, open-source invoicing platform designed to help you create invoices, track payments, manage expenses, send quotes, and automate billing—all without subscription lock-ins.

You can use it in two ways:

• Hosted version (free + paid tiers)
• Self-hosted version (100% free and open source)

That means you get flexibility, control, and the freedom to scale without worrying about rising SaaS fees.
