• Shopify checkout and order events are routed to SpeedTax to request jurisdiction-based tax quotes using ship-to address, nexus context, and line-level details.
• Order data mappings pass SKU, quantity, unit price, discounts, shipping charges, and taxability codes (when available) so tax is calculated per line and summarized on the order.
• SpeedTax tax response values are written back to Shopify as order tax lines, with rounding handled at the platform’s supported precision.
• Delta updates trigger recalculation when relevant fields change, including address edits, line changes, cancellations, and refund or return activity.
• Refunds and partial refunds sync as adjustment transactions so SpeedTax records match Shopify’s financial status and captured amounts.
• Sync jobs log request IDs, timestamps, and error payloads for traceability during tax reconciliation and audit support.
