The service provides both integrated and standalone features to support e-commerce, marketplace, and online platforms. These features help businesses model transactions, automate tax calculation, support compliance requirements, and manage complex indirect tax scenarios across jurisdictions.

Support direct and marketplace transactions

Most e-commerce transactions involve two parties: a buyer and a seller. These transactions are referred to as direct-to-consumer or two-party transactions. In some scenarios, a third party—a marketplace—facilitates the transaction between a buyer and a seller. These transactions are referred to as marketplace or three-party transactions.

Each business model requires a distinct approach to tax calculation, liability determination, validation, and invoicing. The service supports both transaction models, enabling businesses and marketplaces to manage tax requirements consistently across jurisdictions.

Support global indirect tax calculation

The service supports a range of global e-commerce taxes, including:

• Sales and Use Tax (SUT)
• Goods and Services Tax (GST)
• Harmonized Sales Tax (HST)
• Provincial Sales Tax (PST)
• Quebec Sales Tax (QST)
• Value Added Tax (VAT)

• Tax-exclusive pricing (common in the United States)
• Tax-inclusive pricing (common in regions like the European Union)

Currency conversions

The service converts currencies for transactions, reporting, and invoicing.

Process refunds and discounts

The service processes refunds for existing transactions and supports both tax-exclusive and tax-inclusive amounts. It automatically adjusts tax amounts according to the configuration.

Model transactions

API integrations create, store, confirm, and manage transactions across e-commerce, marketplace, and online platforms.

Model marketplaces and sellers

Configure e-commerce, marketplace, and online platforms to control tax outcomes and compliance.

Classify products

Taxability drivers represent the core aspects of your business that drive taxability. Among these, product classes represent the general categories of goods and services businesses sell and purchase, rather than specific products.

The service identifies products as:

• Physical—The tangible goods shipped to a location. Liability is often determined by this location.
• Shipping—The shipping model for physical goods.

Return comprehensive tax information

The service returns comprehensive tax information for both integrated and standalone reporting and auditing.
