📖 In This Post: Posting on Facebook is not a marketing strategy. It's a single channel. A true Marketing Information System (MkIS) tells you which products customers actually want, how price changes affect demand, and where to focus your limited resources. This post transforms guesswork into data-driven audience understanding.
1. Introduction: From Guessing to Knowing
"Post more on Facebook." It's the most common advice small business owners hear. But after weeks of posting, you're still not sure what works. Which products do people actually want? Would raising prices hurt sales, or increase profit? Should you stock more of item A or item B?
These are marketing decisions. And like all good decisions, they should be based on data, not intuition. A Marketing Information System (MkIS) collects, analyzes, and distributes the information you need to understand your customers, track product performance, and set prices that maximize both sales and profit.
🎯 The Core Question an MkIS Answers:
"What do my customers truly value, and how do I reach them profitably?"
2. What Is a Marketing Information System?
A Marketing Information System (MkIS) is a structured system for gathering, analyzing, storing, and distributing marketing-related data to support decision-making. In plain language: it's how you turn customer behavior and market trends into actionable marketing intelligence.
🔑 Core Components of an MkIS:
- Internal Records: Sales data, customer purchase history, inventory levels
- Marketing Intelligence: Competitor pricing, market trends, customer feedback
- Marketing Research: Surveys, focus groups, product testing
- Analytical Tools: Spreadsheets, dashboards, basic statistics
For a small business, an MkIS might be as simple as a spreadsheet tracking weekly sales by product, a notebook recording customer comments, and a monthly review of competitor prices. The key is systematic collection, not random observation.
3. Beyond Posting on Facebook: What Real Marketing Data Looks Like
Social media metrics (likes, shares, comments) are vanity metrics. They feel good but rarely translate directly into sales. A true MkIS focuses on actionable metrics that directly affect your bottom line.
Product Sales Rank
Which products sell fastest? Which sit on shelves? Track units sold per product weekly.
Price Elasticity
When you change a price, do sales drop? Increase? Stay same? Track before/after.
Peak Buying Times
What days and hours do customers buy most? Schedule posts and staff accordingly.
Customer Source
How did each customer find you? (Friend, Facebook, market stall, Google) Track sources.
💡 Example: A craft seller noticed her Facebook posts got many "likes" but few sales. Her MkIS revealed that most actual sales came from WhatsApp messages to repeat customers. She shifted focus to building a WhatsApp broadcast list, and sales doubled.
4. Tracking Which Products People Love Most
You don't need expensive software to know your best-sellers. A simple product ranking system can transform your inventory decisions.
📊 Simple Product Tracking Template
📌 Insight: The scarf sells most units, but the bag has highest profit margin. Which deserves more shelf space? Your MkIS helps you decide.
Advanced tip: Add a column for "Customer repeat rate." If one product has high repeat purchases, it may deserve promotion even if unit sales are lower.
5. Using Data to Set the Right Prices
Pricing is one of the most misunderstood aspects of small business. Many owners either price too low (leaving money on the table) or too high (losing customers). Data removes the guesswork.
📈 The Price Experiment Method
Choose one product. For two weeks, keep price the same, track sales. For next two weeks, raise price by 10%. Track sales again. Compare:
- If sales drop less than 10%, you increase total revenue (keep higher price)
- If sales drop more than 10%, you lose revenue (return to original price)
- If sales stay same, you were underpricing (keep higher price)
Add fixed markup to cost. Simple but ignores customer demand.
Match or slightly beat market price. Requires regular competitor tracking.
Price based on customer perception. Best for unique products.
🔍 Case Example: A honey producer raised prices from 150 to 180 birr per jar. Sales dropped 8%, but revenue increased 10% (92 jars × 180 vs 100 × 150). Profit rose. Data justified the increase.
6. Simple Tools to Build Your MkIS Today
Google Sheets
Free templates for sales tracking, product ranking, and price experiments. Shareable with team.
Facebook/Instagram Insights
Basic demographic data and post performance. Use to understand who your followers are.
Simple Customer Feedback Form
Paper or Google Form asking: "How did you hear about us? What would you like to see more of?"
📝 Your First 3 Steps with MkIS:
- Create a product sales ranking sheet: List all products, track units sold weekly for 4 weeks
- Add a "customer source" question: Ask every buyer "How did you find us?" Record answers
- Run one price experiment: Choose one product, test a 10% price change, compare results
7. Academic Foundation: The MkIS Model
According to Kotler & Keller (2016), a Marketing Information System consists of three subsystems:
- Internal Records System: Sales, costs, inventory, customer data
- Marketing Intelligence System: External data on competitors and market conditions
- Marketing Research System: Custom studies for specific decisions
For small enterprises, the internal records system is the most immediately valuable. Start there. As you grow, add intelligence (monitoring competitors) and then research (customer surveys).

9. Conclusion: Know Your Customer, Grow Your Business
A Marketing Information System transforms marketing from guesswork into a science. It tells you which products deserve more investment, which prices maximize profit, and which channels actually bring customers. You don't need a degree in data science, just a commitment to track, test, and learn.
🚀 Your First Step Today
Open a spreadsheet. List your top 5 products. For each, write down: units sold last week, profit margin, and customer feedback. That's the beginning of your MkIS.
One spreadsheet. Smarter marketing.
Key Takeaways
- MkIS turns customer behavior into actionable marketing intelligence
- Track product sales rank, profit per item, and customer source weekly
- Test price changes with small experiments before committing
- Vanity metrics (likes) ≠ actionable metrics (sales)
- Free tools (spreadsheets, Facebook Insights) are enough to start
- Record every customer comment—it's free market research
