Connect Commercetools with Avalara to calculate and file sales tax with up-to-date rates, cleaner order data, and fewer checkout surprises across regions and channels.
• Tax calculation requests are sent from commercetools to Avalara based on cart or order events, typically including ship-from, ship-to, line items, discounts, shipping, and currency.
• SKU, product tax code, and item classification values are mapped from commercetools product data to Avalara’s taxability inputs, with fallbacks for missing codes handled per agreed rules.
• Avalara returns jurisdiction-level tax details that are written back into commercetools as tax amounts and rates on line items and shipping, preserving rounding logic per order context.
• Address validation and tax estimation can be routed through Avalara during checkout, with final tax recalculated on order placement to reduce mismatches after edits.
• Document and transaction references are correlated between systems using commercetools order IDs and Avalara document codes, supporting later reconciliation and audit trails.
• Error handling logs failed tax calls with request payload context, and retry logic can be applied for transient API failures without duplicating committed tax documents.
