• Salesforce accounts, contacts, and ship-to addresses are mapped to Avalara customer records, with validation of postal codes, region codes, and address completeness.
• Product and line item tax codes (for example, Avalara tax codes) are mapped to Salesforce products or price book items to support consistent classification.
• Tax calculation calls are triggered from key quote and order events, sending document date, origin, destination, item detail, quantities, discounts, and shipping amounts to Avalara.
• Avalara returns calculated tax by jurisdiction, which is written back to Salesforce quote, order, or invoice totals, with line-level breakdowns stored when available.
• Exemption certificates and customer taxability status are referenced via customer identifiers; exemption flags are applied to documents based on mapped fields.
• Committed documents in Avalara are linked to Salesforce transaction IDs; updates and voids are handled as document adjustments to preserve an audit trail.
• Errors and timeouts are logged with request payload references and response codes, supporting reprocessing of failed tax transactions and reconciliation.

Why choose scandiweb to handle Salesforce integration for you?
How do you connect Salesforce to Avalara for real-time sales tax calculation on orders and invoices?
We map address, nexus, product tax codes, and customer taxability in Salesforce, then call Avalara during quoting, ordering, or invoicing. Tax is returned to Salesforce in real time and stored on the transaction record for auditability.
Does the Salesforce Avalara integration support exemption certificates and tax-exempt customers?
Yes – we sync exemption status and certificate references, and apply tax rules based on customer type and ship-to location. This reduces manual overrides when a buyer is exempt in one state but not another.
What Salesforce objects and data fields are required for an Avalara AvaTax integration?
Typically you need clean ship-from and ship-to addresses, line items with SKU or tax code, and a consistent document ID for each transaction. We also align currency, discounts, freight, and shipping methods so Avalara can calculate tax correctly.
Can Avalara handle multi-state and multi-entity tax rules when Salesforce runs multiple storefronts or business units?
Yes – Avalara supports nexus rules across states and can separate reporting by company code, entity, or channel. We implement routing logic in Salesforce so each transaction is sent with the right company context.
