Paid out in pesos. Stores based in Mexico can run Shopify Payments, and payouts arrive in Mexican pesos. Through Shopify Payments, Shopify's docs list meses sin intereses: interest-free monthly instalments on credit cards, charged in MXN. Ask your expert how they'd present instalments on product pages and how they'll test them before launch.
Tax is manual. Shopify offers neither Shopify Tax nor its Basic Tax service for Mexico. Manual Tax is the only built-in route: you or your expert enter and maintain the rates, and third-party tax apps are allowed. Shopify's taxes index has no Mexico-specific guide, so get the rates from your accountant, in writing, before anyone types them in.
Retail hardware. For a shop counter in Mexico, Shopify's own hardware store is not an option. Instead, Shopify tells Mexican merchants to get supported POS devices through third-party retailers, so an expert planning the set-up should match each device to the kit Shopify supports before anything is bought.
Spanish end to end. Your team can work in a Spanish-language admin, and shoppers pay through a Spanish checkout. Product pages, policies and order emails still need Spanish written for Mexican shoppers, which is a writing job rather than a setting.
The red flag. An expert who assumes a US-style set-up carries over. Shopify automates nothing about tax here, and instalments only help if they're set up and tested.
