A Demand Prediction and Group Purchasing System to Solve Inventory Shortages and Waste for Local Cafes

Small cafes often struggle with accurate demand forecasting, leading to stockouts or waste. This service analyzes individual cafe sales data to predict required ingredients and connects them with nearby cafes for group purchasing. This reduces inventory waste and lowers unit costs, improving profitability for small business owners.

Small cafes often struggle with accurate demand forecasting, leading to stockouts or waste. This service analyzes individual cafe sales data to predict required ingredients and connects them with nearby cafes for group purchasing. This reduces inventory waste and lowers unit costs, improving profitability for small business owners.

Why This Idea

Unlike franchises, independent cafe owners lack systematic demand forecasting and rely on intuition for ordering ingredients. This leads to issues where short-shelf-life items like milk, beans, and desserts are either wasted or run out, causing missed sales opportunities. With rising inflation increasing ingredient costs, small business owners have a peak need for cost reduction. Additionally, advancements in POS data integration and data analysis models have created an environment where even small shops can adopt sophisticated demand forecasting and automated ordering systems at a low cost. Service Planner/PM: Analyzes the ordering process and pain points of small cafe owners, defines MVP specs, and designs the group purchasing matching logic. Backend Engineer: Builds a secure pipeline to collect/process POS data from multiple stores, and develops a location-based group purchasing matching algorithm and automated ordering system.

Why This Problem Must Be Solved

Tens of thousands of independent cafes nationwide struggle with the daily headache of ordering ingredients. While large franchises maintain optimal inventory through systematic logistics and data analysis from headquarters, independent cafe owners write orders relying on intuition, calculating yesterday’s sales, tomorrow’s weather, and the day of the week. This rule-of-thumb ordering inevitably leads to inventory shortages or surpluses. Ingredients with short shelf lives, like milk or fresh fruit, must be discarded completely after just a few days, directly resulting in store losses. Conversely, if there’s a sudden influx of customers and ingredients run out, owners must urgently buy materials at expensive retail prices from nearby marts or lose sales opportunities entirely because they can’t sell the menu items. According to statistics from the Small Enterprise and Market Service, the average food waste rate in small food and beverage stores reaches 10-15%, which is a major cause of eating away at operating profit margins. Existing food distribution platforms simply supply goods at wholesale prices; they don’t tell owners ‘how much’ to buy. Cafe owners spend too much time and mental energy on ordering and inventory management rather than their main jobs of making drinks and serving customers, and there is an urgent need for a solution that fundamentally solves this problem.

Why Now Is the Right Time

There are three main reasons why now is the optimal time to solve this problem. First, global inflation and climate change have caused the prices of core cafe raw materials like beans, milk, and sugar to skyrocket. Because of this, managing the cost-of-goods-sold ratio has become the top priority for cafe survival, and the willingness to pay for cost-reduction solutions is higher than ever. Second, the spread of cloud POS and delivery apps has digitized individual store sales data, making it accessible in real-time. Sales ledgers that were manually written in the past can now be easily integrated via API, making it very easy to apply data-driven prediction models. Third, the digital transformation of the B2B food distribution market is accelerating. As the transition from traditional offline wholesalers to online platforms occurs, an infrastructure has been established where automated services based on order data can be integrated. While startups helping with restaurant inventory management overseas are growing rapidly by attracting tens of millions of dollars in investment, there is still no clear leader in a sophisticated prediction and group purchasing platform specialized for the domestic small cafe market, making it a blue ocean.

The Change This Creates

This service acts as a ‘digital franchise headquarters’ for independent cafe owners. Without the owner having to agonize every night over writing an order form, the system comprehensively analyzes POS sales data, weather, day of the week, and local event schedules to accurately notify them, ‘You need 15 packs of milk and 2kg of beans tomorrow.’ Furthermore, it doesn’t just stop at prediction; it automatically creates a local ‘group purchasing group’ by bundling the expected demand of other nearby cafes. For example, 5 cafes within a 2km radius can order 100 packs of milk at once from a wholesaler, drastically lowering the unit purchase price. Delivery is also consolidated to a local hub or the route is optimized, reducing logistics costs. The owner simply checks the recommended order quantity on the app and presses the ‘approve’ button to complete all orders. Through this, the inventory waste rate can be reduced to near zero, food purchase costs lowered by an average of 10-20%, and the time and stress spent on ordering drastically reduced. The ultimate vision is to build the stamina for small business owners to compete with large franchises through data-driven efficient operations.

Why This Approach Works

The biggest differentiator from existing B2B food markets or inventory management apps is the unique approach of ‘demand prediction-based local group purchasing.’ While simple lowest-price searches or inventory recording apps require the owner to put in the effort themselves, this solution ‘proposes’ and ‘automates’ optimal actions based on data. In particular, location-based group purchasing matching creates powerful network effects. As more cafes use our service in a specific area, the group purchasing volume increases, lowering the unit price and increasing delivery efficiency. This forms a local barrier to entry (lock-in) that latecomers cannot easily overcome. Also, as store sales data accumulates, the prediction algorithm becomes more sophisticated, creating a virtuous cycle that leads to accurate ordering and cost reduction. Initially, by focusing on general-purpose, high-turnover core items like milk and beans, we can maximize prediction accuracy and the utility of group purchasing, and quickly preempt the market through a strategy of gradually increasing the items handled.

How Far This Can Go

The number of coffee shops in Korea has exceeded 100,000, and the vast majority of them are independent cafes. Considering the food costs they spend every month, the initial target market (SOM) alone reaches hundreds of millions of dollars. The service’s growth will occur in three stages. Stage 1 verifies the local hub model and creates success stories centered on dense cafe areas in Seoul/the metropolitan area (e.g., Hongdae, Seongsu, Gangnam). Stage 2 expands to major commercial districts nationwide and broadens the target audience from cafes to small bakeries and dessert shops. Stage 3 diversifies the business model into a new product testbed or target marketing platform based on accumulated hyper-local consumption data. Furthermore, this model has very high scalability not only in Korea but also in Asian markets like Japan and Taiwan, where the proportion of independent cafes is high. Ultimately, it has the potential to establish itself as an ‘integrated supply chain management (SCM) operating system for small F&B stores,’ expecting mergers and acquisitions (M&A) by large food distribution companies or IT platforms, or an independent initial public offering (IPO).
