Many brands that have been selling products for decades, generating hundreds of millions in annual revenue, and having their products placed in department stores and convenience stores nationwide, still face a surprising issue. When asking their marketing department, “Who is actually buying our products?” the answer is often silence—or a broad answer based on guesswork and external research rather than real data from actual buyers.
This isn’t unusual; it is an unseen problem facing many large brands in Thailand, creating a gap that makes marketing increasingly difficult today.
Why Big Brands Don’t Really Know Their Customers
1. Selling Through Middlemen (Distributors/Retailers) Cuts Off Direct Connection
Most brands sell through department stores, convenience stores, or distributors. Transactions happen directly between retailer and customer, leaving brand owners with zero data on who bought the item. All they receive is the total sales figures reported back by distributors.
2. Over-Reliance on Third-Party Data
Many brands rely heavily on purchasing target demographic data from ad agencies or using Facebook/Google Ads insights. These sources only offer a “broad picture” of audiences likely to be interested—not direct data on actual buyers. As platform privacy policies tighten, this data becomes less accurate and more costly.
3. Lack of Touchpoints Encouraging Customer Feedback/Data
Most products are designed purely to “sell,” with no feature on the packaging or in the purchase process that invites customers to register or provide information. Even paper warranty cards or reward redemption forms from the past are usually discarded due to complicated steps, causing brands to miss out on collecting real customer data.
4. Existing CRM Systems Collect Purchase History, Not Customer Identities
While some brands have CRM or membership systems, the data collected is often limited to transaction history through retail outlets rather than personal details—such as names, phone numbers, addresses, gender, birthdays, or product satisfaction/behavior—which are the insights needed to drive effective marketing campaigns.
The Consequences of Not Knowing Your Customers
- Rising Marketing Costs: Brands rely repeatedly on broad-targeting ads instead of communicating directly with existing customers who are already inclined to repurchase.
- Missed Opportunities for Loyalty: Brands cannot run personalized campaigns or offer special perks to regular customers because they don’t know who those loyal buyers actually are.
- Slow Response Times: In the event of product quality issues or counterfeiting, brands cannot directly notify affected customers because they lack saved contact channels.
- Decision-Making Based on Guesswork: Marketing campaigns are guided by assumptions rather than real data, leading to efforts that miss what customers actually want.

First-Party Data: The Solution Brands Must Start Building Today
First-Party Data is customer information collected directly by the brand without relying on intermediaries or ad platforms. It is the most accurate data and serves as a long-term business asset. As third-party cookies phase out and personal data privacy laws become stricter, the value of First-Party Data will only continue to rise.
One of the simplest and most effective ways to collect First-Party Data is using QR Codes on products as a touchpoint for voluntary registration, backed by proper incentives:
- Lucky Draws or Points Collection: Motivates customers to scan and submit their details without cutting out product proofs or carrying physical loyalty cards.
- Authenticity Verification: A natural entry point for data collection, as customers already want peace of mind knowing their product is genuine.
- Short Post-Purchase Surveys: Helps brands understand purchase reasons and real customer satisfaction levels.

With complete customer data—including names, phone numbers, emails, addresses, gender, birthdays, and behaviors—brands can run dashboard analytics for precise marketing planning. This includes segment-specific campaigns, automated birthday messages, or analyzing high-density customer areas to plan market expansions.
Conclusion
Selling products for years does not mean a brand automatically knows its customers. Without a system designed to capture real customer data directly, brands will continue relying on guesswork and external data for marketing decisions.
Starting First-Party Data collection through existing touchpoints—like QR codes on packaging—doesn’t just help brands get to know their real buyers; it is a long-term investment that makes marketing more precise and cost-effective over time.
