AI predicts customer volume to prepare ingredients

In the fiercely competitive F&B industry, accurately predicting the number of customers and food demand is the key to helping restaurants optimize operations.

Instead of relying on intuition or manual experience, AI (artificial intelligence) is becoming a breakthrough tool, helping chefs and managers accurately forecast the number of customers, prepare enough ingredients, reduce waste and save costs. This is not only a technology trend but also a sustainable solution for the future of the global culinary industry.

In this article, we will learn more about how AI predicts the number of customers to prepare the most optimal ingredients, during the operation of the kitchen and restaurant!

Why Forecasting Matters?

Restaurants often struggle with unpredictable demand and food waste. In fact, about one-third of food produced is never eaten, and U.S. restaurants alone waste an estimated $162 billion worth of food each year.

Overordering ties up capital in spoilage, while underordering leads to stockouts and missed sales. This makes accurate forecasting critical: by estimating customer volume and popular menu items, operators can adjust ingredient orders to match real needs and cut waste.

Rapid Growth of AI in Foodservice

The market for AI in food and beverage is booming. A 2025 industry report predicts the global AI market in food and beverages will grow by about $32.2 billion (2024–2029, 34.5% CAGR). AI-powered systems promise to “revolutionize restaurant management by enhancing efficiency, reducing costs, and improving customer satisfaction”.

Notably, data-driven AI forecasting can also support sustainability: a McKinsey analysis estimated that AI-driven matching of supply to demand could unlock up to $127 billion in annual value by cutting food waste. In other words, smart ordering directly saves money and resources.

AI Demand Forecasting in Restaurants

AI demand forecasting uses machine learning to predict future sales and customer counts by analyzing data. Instead of simple spreadsheets, these systems ingest point-of-sale (POS) records, sales history, and even sensor inputs (like reservation or foot-traffic data) to anticipate trends.

In practice, restaurants use AI models to forecast seasonal demand, flag peak time slots, and allocate staff and inventory accordingly. For example, IBM notes that chains rely on AI to “predict seasonal demand and avoid overstocking perishable items”. These forecasts can, for instance, ramp up prep for a holiday crowd and then scale back afterward, keeping inventory balanced.

Data and Technology for AI Forecasting

Advanced AI forecasting draws on a wide variety of data. It combines basic sales history with external drivers like weather, special events, and promotions. As IBM explains, AI models can use data from IoT (Internet of Things) devices, economic indicators, weather forecasts, and social media sentiment to reveal demand patterns.

For instance:

  • Historical sales: Year-over-year POS data by daypart, enabling baseline demand curves.

  • Calendar factors: Day of week, holidays, and local event schedules (concerts, sports games, festivals) that affect foot traffic.

  • Weather conditions: Temperature and precipitation forecasts (rainy Tuesday evenings might boost soup orders).

  • Promotions and trends: Special menu promos or viral food trends on social media.

Modern forecasting models include advanced machine learning techniques. Algorithms like neural networks, gradient-boosting trees, or time-series models capture complex, non-linear demand patterns.

For example, a 2025 study of a university cafeteria found that an XGBoost model (a type of ensemble algorithm) achieved very high accuracy in predicting daily customer counts by combining features such as prior-day traffic, holidays, and weather data. Over time, these models can adapt and improve continuously as more data becomes available.

AI in Kitchen Automation

Modern restaurants are also using AI-powered automation in the kitchen. Some chains deploy robots or smart appliances to prep food consistently while chefs focus on cooking. Meanwhile, machine-learning algorithms analyze demand data to guide these systems.

For example, an AI might learn that “rainy Tuesday evenings consistently drive higher soup sales”, so the kitchen thaws extra broth and chops more vegetables in advance. By merging robotic efficiency with data-driven insights, restaurants can ensure they have exactly the right ingredients ready when customers arrive.

Benefits of AI Forecasting

Using AI to predict customer volume offers multiple payoffs:

  • Reduced food waste: AI-driven ordering helps use up ingredients before they spoil. Studies show AI inventory systems can cut kitchen waste by about 20% or more. In practice, one chain using an AI/ML forecast saw inventory waste drop by 10%.
  • Lower costs: Better forecasts mean less overstocking. One case study reported a 20% reduction in labor costs (through optimized scheduling) along with significant food cost savings after switching to AI forecasts.
  • Improved freshness and availability: By ordering precisely what’s needed, restaurants keep ingredients at peak freshness and never run out of popular dishes.
  • Operational efficiency: Automated forecasts free staff from manual calculations. Systems can auto-generate orders or prep lists based on predicted ticket volume, speeding up procurement and reducing errors.

Real-World Examples

Many restaurants and tech firms are already leveraging AI forecasting:

  • Fast-casual chain: A major U.S. restaurant group replaced its legacy forecast tools with an AI/ML system and achieved 20% higher labor cost savings and 10% less inventory waste.
  • AI waste-tracking: Solutions like Winnow Vision use cameras and AI to identify food scraps. In trials, a kitchen using Winnow cut its food waste by about 30% within a few months. (Competitors Leanpath and Kitro use similar sensors to monitor waste and guide portioning.)
  • AI-driven menus: McDonald’s has rolled out AI-powered digital menu boards in 700 U.S. restaurants. These systems suggest items based on factors like weather and time of day, aligning menu offerings with predicted demand peaks.

Real World AI Applications in Restaurants

Implementing AI Forecasting

To get started, restaurants should follow a structured approach. For example, IBM recommends steps like:

  1. Assess objectives: Define what needs forecasting (e.g. overall covers, specific menu items, peak hours).
  2. Choose tools or partners: Select AI software or consultants that specialize in hospitality demand planning.
  3. Collect quality data: Ensure clean, accurate POS and inventory records. Integrate new feeds (weather APIs, local event calendars, etc.) as needed.
  4. Involve stakeholders: Train staff on how forecasts inform ordering, staffing, and prep decisions. Gain buy-in by showing AI’s value.
  5. Monitor and refine: Continuously evaluate forecast accuracy and update models over time as new data comes in.

Challenges and Future Outlook

Adopting AI forecasting also presents challenges. Smaller restaurants may lack the budget, data infrastructure, or technical expertise to deploy sophisticated tools immediately. Integrating disparate systems (POS, kitchen inventory, supplier catalogs) can be complex.

Data quality issues (incomplete sales records or changing menus) can hamper accuracy. However, as cloud-based AI platforms become more affordable and turnkey, even independent cafes can leverage these tools.

Looking ahead, AI-driven insights are likely to play an even bigger role as restaurants integrate IoT sensors and predictive analytics into all aspects of their operations.
