Most billing software sells you the kitchen sink — inventory you don't stock, a chart of accounts you'll never touch, and three extra clicks on every invoice. Simple Billing started as a reaction to that.

The only question we optimise for: how fast can you go from “I need to bill this client” to a PDF in their inbox? Everything in the product — customers, catalog items, GST-ready tax presets, payments, and reports — is built around that one outcome.

Whether you're a consultant in Bangalore, an exporter in Chennai, or an agency billing clients across currencies, the workflow is the same: create the invoice, send the PDF, record what comes in, follow up on what doesn't. No accounting degree required.
