Note that if invalid company code credentials are provided, taxes will still be applied to an exempt product in invoice. This is because we do not have control over the third-party company code validation and hence authentication will not fail at the integration page.

Configuring Tax Codes for your Plans and Addons 

Vertex uses a Product Code and Product Class to determine the tax rate for each product. Taxable, nontaxable, and partially taxable products are automatically differentiated using these product codes and classes.

After configuring Vertex for your Chargebee site, the Vertex Product Code and Product Class fields are displayed for Plans, Addons, and Charges Price Points. You can add the corresponding codes.

Configuring Customer Tax Exemptions 

If you'd like a particular customer to be exempted from tax, you can configure the exemption while creating the customer in Chargebee by:

  1. Enabling the option This customer is exempted from tax payment on the customer details page.
  2. Specify the Customer Code and Customer Class fields to map the exemption reasons.

Validating Addresses for Existing Customers 

The Chargebee-Vertex integration validates the taxable address for all new customers who subscribe with your service after enabling Vertex. For customers who have signed up before enabling Vertex, Chargebee will cancel their subscriptions during renewal if tax cannot be determined. Subscriptions on the verge of cancellation can be determined using the Validate Existing Addresses feature that allows you to view and fix invalid addresses.

Under Validate Existing Addresses, select your taxable region - United States from the drop-down, and click Run Check.

During the first check that is run after the integration is configured, all the existing subscriptions' taxable addresses gets validated. Subsequent address validations will check only the addresses that are added after prior validation and not all the addresses. You can look for any possible address errors and have them fixed.


Note that validating addresses is not a full address validation but a taxability check.

Enabling Vertex for Tax Calculation for Taxable Regions/United States 

This is a crucial step of this integration. Unless you execute this step, Vertex will not be used for automatic tax calculation in Chargebee. After connecting the Vertex account with your Chargebee site, click Go to Taxes on the Vertex app page.

Alternatively, you can click Settings > Configure Chargebee > Taxes.

Go to the taxable region - United States and select Vertex as your preferred mode of tax calculation.

To unlink the Vertex integration from your Chargebee site, follow these steps:

  1. Click Settings > Configure Chargebee > Taxes and switch from Vertex to your preferred mode of tax calculation for United States, by clicking Change.
  2. Navigate to Apps > Apps Connected > Vertex > Manage, and click Unlink integration.
