Billbooks

Billbooks is invoicing software for small businesses and contractors, founded in 2010 by Sagar Kogekar and run from St Leonards, New South Wales. It covers estimates, invoices, recurring billing, expenses and online payment through Stripe, PayPal, Square and Razorpay, in multiple currencies.
