Domillio is an integrated software suite of specialized regulatory compliance applications for Shopify merchants. We provide sovereign, audit-ready solutions across wholesale sales tax exemptions, children's toy safety (CPC/CPSIA), European cross-border regulations (GPSR 2023/988), European packaging recycling (EPR/VerpackG), and California Proposition 65 clear warning defense.
When a merchant approves a buyer's resale permit or 501(c)(3) certificate, the app automatically executes a Shopify Admin GraphQL mutation updating the customer's account with taxExempt: true and adds a custom tag (e.g., 'tax-exempt'). Subsequent orders placed by that logged-in buyer automatically calculate zero sales tax at checkout without manual refund processing.
