Kalki Invoice is a cloud-based system to manage your invoices, payments, quotations, and customers with multiple billing companies, taxes, custom fields, user roles and permissions, recurring invoices, online payments, product modules, payment options, and advance reports.

The most interesting and unique feature of this system is the drag-and-drop invoice template builder, where you can create your own invoice template without any coding knowledge. This system comes with seven popular online payment gateways, such as PayPal, Stripe, Razorpay, PayStack, Flutterwave, InstaMojo, and Mollie. Payment gateways are mainly used for subscription payments as well as accepting invoice payments from customers.
