SP-API 与税务发票SP-API & Tax Invoicing
为什么需要 Tax Invoicing 角色Why We Need the Tax Invoicing Role
Amazon Selling Partner API（SP-API）的 Tax Invoicing（税务发票） 是受限角色，用于与税务发票相关的合规操作。致远开票通仅将该角色用于授权卖家的税票归档、导出与财务交接；不用于广告、库存优化、跨卖家分析或数据转售。 The Tax Invoicing role in Amazon's Selling Partner API (SP-API) is a restricted role for tax-invoice-related compliance operations. YSZY Tax Invoice Hub uses it only for the authorizing seller's invoice archiving, export and financial handoff — never for advertising, inventory optimization, cross-seller analysis or data resale.
