Harry Lewis

Founder of Saasybill. Billing for Xero.

About

I'm Harry, an 18 year old solo founder from Australia. I started building Saasybill at 15 because my dad came to me with a billing problem: his SaaS billing had outgrown Xero, but every billing platform they looked at would take over their invoicing, charge a cut of their revenue, and leave their accounting in two places at once. So I built something that sits alongside Xero instead of replacing it. It's now live.

Saasybill - Subscription billing automation built for Xero

Most billing tools want to own your invoicing. Saasybill doesn't. Every invoice is created directly inside Xero, so your accounting stays intact, your accountant doesn't need to change anything, and you're not paying a percentage of your revenue to process bank transfers. Set up your plans, attach subscriptions to customers, and billing runs automatically at renewal. Flat subscription pricing, no transaction fees.
