Focus on doing what you love.

Our services are designed specifically for small- to medium-sized companies and freelancers because we know how difficult it can be to juggle hefty software costs and financial admin while you’re trying to focus on the rest of your business!

Invoice Ninja software suites are fast, free, and straightforward without any specialist accountancy knowledge needed to get stuck in. Choose from multiple currencies and languages for overseas customers, set up automatic reminders for late payers, and transform quotes into invoices at the touch of a button.

We provide everything you need to get going, including invoice templates, a personalized dashboard, and recurring invoice settings, so you can sit back with the assurance that repeat invoices will be created, logged, and sent to your client effortlessly.

Free invoicing software is an easier, faster, and smarter way to get paid, issuing professional, customized, and official invoice documentation to your clients in seconds–leaving you free to concentrate on everything else.

Admin is never the most exciting aspect of running a business, but it’s beyond necessary! Using innovative, speedy invoicing software has countless benefits, whether you’re a freelancer, a one-person band, or just getting a start-up off the ground.

Invoice Ninja takes the time out of invoicing, helping you avoid payment delays or spending hours typing out invoices one at a time, eliminating the immediate knock-on impact on your cash flow and business bank balance. Our invoices are created digitally, so you can log into your account and shoot an invoice to your client from any device, uploading your logo and payment information to facilitate remittances directly from your client.

Best of all, our invoicing software is totally free for up to twenty clients, without any hidden catches, surprise credit card charges, or limitations on the number of invoices you can send. We even throw in four templates, custom branding, and online payments without charging a cent.

You are never forced to upgrade! However if you choose to upgrade you gain access to unlimited clients + awesome features!

Where do I begin?

2. Upload your logo & choose an invoice design
3. Integrate your payment gateway

A merchant processor is also called a ‘payment gateway‘. After integrating a payment gateway with your Invoice Ninja account, your clients will see a “Pay Now” button on their invoices.

What is a Merchant Processor/ “Payment Gateway”

The ‘payment gateway’ processes your clients payment and your clients never leave their Invoice Ninja client-portal.

The payment gateway then deposits the money into your bank.  

Invoice Ninja supports dozens of payment gateways, click here for the full list.

We take security seriously and provide invoicing software with the latest data protection and cybersecurity safeguards to protect your information, billing details, and client contact information. Issuing invoices through our secure portal is massively safer than attaching invoice files to emails, which are vulnerable to hacking and data breaches as they travel from one server to the next.

Invoice Ninja is compatible with all the major payment gateways, including Stripe, PayPal, and WePay, ensuring you get paid quickly without any of the risks of sharing confidential financial details over a message, phone call, or email.

There are multiple functions to encrypt and secure your data and invoices, with multi-factor authentication, automation to cut down on errors, secure logins linked to your approved devices or users, and cloud-based data storage to dodge any issues with lost hard drives or crashed computer systems.

Cybersecurity is active 24/7, whether you’re busy catching up on late-night admin or logged off for the evening, with security tools at the level you’d expect from any banking provider or credit firm.
