How Navigator iConnect Sales Tax Automation connects to SAP Business One
Navigator iConnect integration tool
iConnect is Navigator's integration product. It sits between the ERP and Avalara, passes transaction data for calculation, and supports return filing automation as described on the vendor page. Business One users commonly run on-prem or hosted, so confirm the deployment and network path to Avalara with Navigator.
