OpenSalesTax for QuickBooks Online
==================================

[](#opensalestax-for-quickbooks-online)

> **v0.1.0-alpha.1.** Installable via `composer create-project`; passes 38 unit tests; PHPStan max + PSR-12 + `composer audit` clean. Live Intuit-sandbox round-trip is a captain follow-up — see `specs/handoff.md`.

A free, self-hostable **webhook sidecar** that adds destination-based US sales tax to [QuickBooks Online](https://quickbooks.intuit.com/online/)invoices via the [OpenSalesTax engine](https://github.com/ejosterberg/opensalestax).

This is the OpenSalesTax replacement for Intuit's per-seat **Automated Sales Tax (AST)** — the same feature, run on the merchant's own infrastructure with the merchant's own data.
