How direct-to-consumer d2c ecommerce brands handle sales tax compliance?

DTC ecommerce brands handle US sales tax compliance by first assessing economic nexus state by state, registering in applicable states, using Shopify Tax or a dedicated sales tax platform to calculate rates at checkout, and filing/remitting either manually or through an automated filing service. For international tax compliance (VAT, duties), Swap's Global platform provides the equivalent layer for cross-border sales.
