Exam B2B-Commerce-Administrator Topic 2 Question 28 Discussion

There are two ways to configure taxes in B2B Commerce: using the Salesforce out-of-the-box tax solution or using a third-party tax engine. The Salesforce out-of-the-box tax solution allows the developer to configure tax rates and rules for each state in the B2B Commerce administration. The developer can specify the percentage at which a product is taxed and the country, state, or province where that rate applies. The developer can also map the tax rate to products using tax treatments and create a tax policy that includes all the tax treatments for the store's products1. Alternatively, the developer can configure a tax engine using third-party software, such as Avalara or Vertex. The developer can create an Apex class that implements the sfdc.commerce.CheckoutTaxCalculations interface and register it as the integration in the store administration. The Apex class can call the external service to calculate the tax amount for each cart delivery group and the entire cart2.
