Mexican online shops prepare for AI that shops on your behalf

Mexican online shops are being urged to get ready for AI helpers that shop for people. The warning comes from Marcos Pueyrredon, president of the eCommerce Institute and co-founder of VTEX, in a column for Mexico Business News published on November 9, 2026.

What is changing

The column calls it "agentic commerce." An AI agent is a program that acts for you. Here, it finds products, compares options, completes purchases and handles after-sale services without the shopper stepping in at each stage. The Mexican Association of Online Sales (AMVO) sees this as the next big shift. Its line: being visible to AI will become as important as being relevant to a human consumer.

Why Mexico is a test case

Mexican retail reached MX$941 billion (US$51 billion) in 2025, up 19.2%. The column says that is 25 times faster than the economy as a whole. The country had 77.2 million active digital shoppers and ranked eighth worldwide in digital penetration, ahead of the United States, according to AMVO.

Shoppers also look open to the idea. Figures from McCann México cited in the column say 70% of Mexicans trust brands that use AI, and 75% believe technology will make their lives easier.

What shops need to get right

An agent can only work with what it can read. Prices, stock and delivery times must match across a shop's systems. If an agent recommends an out-of-stock item or promises an impossible delivery date, a sale turns into a complaint.

Trust is the other condition. McCann México found that 53% of Mexicans say full openness about how AI is used is the best way to build credibility. The author proposes written rules for what an agent may decide for a brand or a buyer. That includes price, which stock to show, when to cancel, what needs a human's approval and who is accountable for mistakes.

What to do

• Check how the catalog looks to an AI agent: is it clear, structured and verifiable?
• Write down the transparency rules that apply when an agent buys or recommends for the shop.
• Test one product category and compare margin per order, errors and repeat purchases against a similar operation without AI agents.
• Count the full cost in that test, including technology, supervision and corrections.

What is not known yet

This is an opinion column, not a new rule or a market report. It does not say how many Mexican shops already use AI agents or give a date for when the shift will peak. The advice is a recommendation, and results will vary by shop.
