When doing e-commerce in Mexico, if a buyer files a complaint with a consumer protection agency, the cost of mishandling the situation goes far beyond a simple refund. This article begins by addressing the three most common lapses in sellers’ obligations—incomplete disclosure of information, failure to comply with the right of withdrawal, and delayed responses to after-sales issues—and provides actionable corrective measures for each. It also provides a checklist for handling complaints: how quickly you must respond, what supporting documentation to prepare, when to issue an immediate refund to cut losses, and how to reduce the complaint rate by optimizing product detail pages.

Many sellers setting prices on the Mexico marketplace only factor in the purchase price and initial shipping costs, only to discover after listing their products that they’re losing money with every sale.

This article works backward through the entire order process to lay bare the category-specific variations in customs duty rates, the conditions for VAT deductions, the significant differences in platform withholding rates depending on whether a tax ID is provided, and the structure of commissions and fulfillment fees. It provides a ready-to-use pricing formula and three self-assessment steps.
