Where do I begin?

1. Create a FREE Invoice Ninja account
2. Upload your logo & choose an invoice design
3. Integrate your payment gateway
4. Create clients, invoices, get paid!

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.  

You will need to integrate a payment platform with your Invoice Ninja account. There are several free platforms available that you can easily integrate so you can start sending invoices and collecting payments.

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.
