There are two types of knowledge in Mexican retail: what you can learn in a course, and what you only learn by having been at the negotiation table, on the sales floor, and in category reviews for years.
This article is about the second type. The unwritten rules that determine whether a brand manages to enter, grow, and stay in Mexico's most important retail chains.
Rule 1: The buyer doesn't buy products — they buy categories
The first mistake sellers and companies make when trying to enter retail is presenting their product as if it were the protagonist of the conversation. For a chain buyer, the category is the protagonist.
The beverage buyer at Soriana isn't thinking about whether your flavored water is good. They are thinking about how to optimize their beverage category space to maximize sales per linear meter. Your job, if you want to get in, is to show them how your product improves the performance of their category — not just why your product is better.
This means that before entering any meeting with a retail buyer, you need to know: which brands are currently in the category, what space is available, which brands have the best turnover, and how your product complements or improves that mix — whether by price, consumer segment, package size, or innovation.
The unwritten rule: speak the language of the category, not the language of your product.
Rule 2: Initial conditions are more important than price
One of the most critical negotiations in retail — and the one with the most long-term impact — is not the selling price. It's the initial entry conditions: margin, payment terms, support, penalties, and exclusivity.
The conditions you sign when entering a chain are very difficult to renegotiate later. Once the buyer knows you accepted X%, they will never want to lower that percentage. Once you've signed for 90 days, asking for 60 will be a battle. That's why initial conditions must be negotiated very carefully — and with someone who knows exactly what ranges are acceptable for your category and your expected sales level.
The unwritten rule: what you sign when you enter is what you will live with for years. Negotiate each initial condition as if it were permanent — because it probably is.
Rule 3: The relationship with the buyer is as important as the product
Mexican retail runs on relationships. Chain buyers have dozens of suppliers and receive dozens of entry requests every month. The difference between who gets in and who doesn't is often not in the product — it's in the relationship.
Building a trusting relationship with the buyer takes time. It requires constant presence, fulfillment of commitments, useful market information, and a partner, not just a supplier, attitude. Buyers work with brands that make them look good — brands that turn over, don't cause stockouts, bring innovation, and communicate problems before they become crises.
The unwritten rule: treat the buyer as your most important customer — because they are.
Rule 4: In-store execution is worth more than any agreement on paper
You can have the best commercial agreement in the world with a chain and still not sell. Because in retail, what determines the final sale is not the agreement with the buyer — it's what happens on the sales floor.
Product availability, correct display, updated pricing, current POP material, product in good condition. Every visit to the sales floor is an opportunity to win or lose a consumer. Brands that consistently grow in retail are those with systematic execution processes — not those that trust the chain to solve everything.
The unwritten rule: the agreement with the buyer opens the door. In-store execution determines if you stay.
Rule 5: Data is your best negotiation tool
Retail buyers live with data. Weekly sell-out, SKU turnover, market share by region, category trends. Suppliers who come to their meetings with data — about their product's performance, the category, the consumer — have a huge advantage over those who only bring brand presentations.
Learning to read, interpret, and use your product's sales data in retail — and your category in general — is one of the most valuable skills any professional or company looking to grow in retail can develop.
The unwritten rule: he who has the data has the power in negotiation. Learn to use it.
Knowledge that makes a difference
These rules are not learned in a two-day course. They are learned through years of practice, costly mistakes, and much market observation. But they can be transmitted — through specialized retail training, mentorships with experts who have lived the process from the inside, and accompaniment during critical negotiation and execution moments.
At Alkimia Comercial, we have been accumulating this knowledge for over 25 years. And part of our mission is to transfer it to companies and professionals who want to sell better in Mexican retail.
