The Vertex integration calculates sales tax as part of the pricing operation. When the shopping cart is priced with a request to include tax pricing, Commerce Cloud sends the information to Vertex, which calculates the total tax amount and sends it in a response. The response breaks down the tax into individual components, for example, the total tax amount might include sales tax assessed by both the state and county.
Commerce Cloud makes two calls to Vertex:
When the shopper begins the checkout process, Vertex responds with the calculated tax amount.
When the order is submitted, Vertex responds with the calculated tax amount.
As part of the settlement process, Vertex updates the tax record with the date of shipment. Commerce Cloud is not involved in the settlement process.
Important: As a merchant, it is your responsibility to add the appropriate tax jurisdictions to your Vertex O Series taxpayer profile. (You set up your taxpayer profile in the My Enterprise section of Vertex Central.) Jurisdictions you add to your taxpayer profile tell Vertex O Series where and when to calculate and report tax. All sales that occur in jurisdictions you have not configured in Vertex O Series result in a tax calculation that returns a value of zero tax. Oracle Commerce Cloud Service is not responsible for configuring or validating jurisdictions. You can find information about nexus and tax jurisdictions in the Vertex documentation, which is available when you log into Vertex Central.
