Avalara - AvaTax

The Avalara AvaTax Integration module connects your PrestaShop store to the Avalara AvaTax cloud-based tax calculation service. It replaces PrestaShop's native tax engine with Avalara's system, enabling automated, address-based tax calculation powered by Avalara's extensive tax code database. Valid Avalara credentials are required to use this module.

• Automatic tax calculation powered by Avalara AvaTax, replacing the native PrestaShop tax system
• Address validation when customers add or modify addresses, with optional uppercase normalisation
• Per-product tax code assignment, with fallback to UPC codes and a configurable default tax code
• Option to restrict or enable tax calculation outside your registered state nexus

This module is designed for PrestaShop merchants — particularly those selling in the United States — who need accurate, jurisdiction-level tax calculation managed through the Avalara platform. Store owners must disable PrestaShop's native tax settings after installation to avoid conflicts. Please note that this module has been marked as abandoned and may not receive further updates or support.
