Avalara Avatax Connector for Ecommerce

This module connects the Avalara AvaTax tax engine to the Odoo eCommerce checkout. It has no menus or screens of its own; instead it changes what happens behind the scenes when a shopper clicks through to pay.

When a customer opens the payment step of the online shop, the module takes the current cart/order and asks AvaTax to compute the taxes again. Only after that recalculation is done does Odoo continue to the normal payment page. This helps make sure the tax shown and charged at checkout reflects the latest AvaTax result, for example after the delivery address or cart contents changed.

It relies on the existing Avalara AvaTax sales connector and the standard Website Sale app, and it installs automatically when both are present. It does not add any new models, fields, buttons, reports or scheduled jobs of its own. The only business behaviour it adds is the automatic tax recalculation on the shop payment step, using the order's _avatax_compute_tax method.
