To set up and manage the Avalara ELR integration, navigate to: Integration > E-Invoicing Provider > Avalara ELR

The page is organized in three sections: the account, the configuration, and the company and mandate mapping.

Avalara ELR Account

Enter the credentials of your Avalara ELR account:

• Client ID — the client ID from your Avalara ELR contract.
• Environment — the Avalara environment the integration connects to, for example SANDBOX for testing.

Avalara ELR Configuration

• Avalara ELR — enables or disables the integration.
• Client Side Logging — enables logging of the communication with Avalara, which helps when analyzing submission issues.
• Submission scheduling — determines when documents are submitted to Avalara, for example On invoice creation.

Avalara ELR Company and Mandate Mapping

A mandate mapping tells instellix under which country mandate the e-invoices of a company are submitted. The overview table shows each mapping with its Ident, Company ident, Company, Invoice address country, Mandate ident (for example NL-B2B-PEPPOL or IT-B2B-EINVOICE), and Validation document ident.

When you create or edit a mapping, you define:

• Ident — the identifier of the mapping.
• Company — the company whose documents the mapping applies to.
• Invoice address country — the invoice address country for which the mapping applies.
• Mandate ident — the Avalara mandate under which matching documents are submitted, for example NL-B2B-PEPPOL or IT-B2B-EINVOICE.

The dialog also provides a JSONata mapping editor with supporting panels (Avalara documentation, JSONata utilities, and a validation document): adjust how the document data is mapped for the mandate, then click Validate to see the JSONata result and the resulting XML for the validation document.
