OCA l10n-usa (Odoo)
Odoo US localisation with a hybrid sales tax engine (local rates first, API fallback), ACH and 1099 modules.
What it does
Odoo modules for US localisation: a sales tax engine that resolves the state, county, city and district rate for a ZIP code, ACH payment files, 1099 suppliers and a GAAP chart of accounts. They run inside Odoo; the engine reads a local rate database first, then external API providers via plug-ins. The engine's README calls it alpha, not for production, with no rate data shipped.
