Why Rechvix exists

Most "billing software" projects either stay a prototype — float-based money, editable stock counts, no real double-entry — or copy an existing commercial product's design wholesale. Rechvix starts from a from-scratch engineering brief that treats the accounting and tax logic as the hard, non-negotiable part, and the UI as something that has to be fast for a billing-counter operator, not just pretty.

It's built by NODEDR INFOTECH PRIVATE LIMITED and Raktim Ranjit, the team behind nodedr-pos — same philosophy, applied to the fuller back office a growing business eventually needs: self-hosted by default, no external connection required to run your business. Core billing, inventory, and accounting work entirely on your own machine — your own PostgreSQL, no mandatory cloud dependency, no phone-home telemetry. The only things that ever reach the internet are integrations you explicitly turn on and that inherently require it — GST e-Invoice/e-Way Bill submission (a government API, required by Indian law for those documents), WhatsApp/email sharing, and optional cloud object storage.

Where it stands today

Rechvix is built in explicit, gated stages — research, architecture, foundation, catalogue/contacts/pricing, inventory, sales/GST, accounting, reporting, government integrations, other integrations, packaging, and the web app. A stage isn't marked done until it has real passing unit and integration tests. All of those are complete and independently verified today — only hardening (security review, load testing, accessibility audit) remains, and it's already underway. See docs/TODO.md on GitHub for exactly what's done versus in progress, updated as it changes.
