Guide: E-Invoicing and Live Reporting

For both outbound (sale) and inbound (purchase) e-invoicing flows, Avalara determines which Avalara company record the document belongs to. All API responses related to the document include the companyId field.

Your integration must map the Avalara companyId to your application’s internal reference for the corresponding legal entity or company. This mapping ensures that your system can process the document correctly.
