Why McDonald’s Invested in Custom Software to Reimagine the Drive-Thru Experience

Nearly 70% of McDonald’s U.S. sales come from the drive-thru, which shows how important it is to the business. To speed up service and boost sales, McDonald’s has aggressively modernized its drive-thrus with custom software and digital tools. Starting in 2019 with its $300 million acquisition of Dynamic Yield, McDonald’s began deploying AI-driven digital menu boards that offer personalized recommendations to customers. These menus change dynamically – suggesting items based on the time of day, weather, restaurant traffic, or trending orders. In practice, this means a rainy afternoon might prompt a “$1.49 apple pie” offer, or a busy lunch period might highlight combo deals to move traffic through faster. By writing its own software (and partnering with specialists), McDonald’s turned static menus into interactive selling platforms tailored in real time to each car’s context.

Digital Menu Boards and AI Personalization

McDonald’s shift to digital signage has been dramatic. By 2020 the company had installed AI-powered menu boards across most U.S. drive-thrus, replacing paper menus entirely. Behind the scenes, McDonald’s custom software pulls data – like current weather or inventory levels – into decision models. If a location is running out of burgers, the system might downplay hamburger upsells and instead promote salads or chicken wraps. Loyalty data (from 150 million MyMcDonald’s Rewards users) is even integrated, so repeat customers might see offers matched to their past orders. The acquisition of Dynamic Yield was key: it provided the recommendation engine that “automates upselling” at the point of sale. In effect, McDonald’s injected the sophistication of an online retailer’s recommendation system directly into its drive-thru.

The technology requires robust development work. McDonald’s teams (with new software) built interfaces to ingest sensor and transaction data, trained machine-learning models on millions of past orders, and created content management systems for regional marketers to adjust promotions on the fly. These custom solutions run in the cloud with edge caching – so menus update quickly even if connectivity blips. The effort paid off: pilots showed up to a 6% increase in average check size thanks to smarter add-ons. In one study of 400 stores, AI-driven boards cut drive-thru times by about 27 seconds on average while lifting throughput 10% and adding roughly $65,000 in annual revenue per store. By automating and personalizing suggestions (like prompted upsells) without slowing orders, McDonald’s software helped orders go through faster and more profitably.

AI, Voice Ordering, and Cloud Integration

Digital boards were just the start. McDonald’s also experimented with voice AI and cloud services to further modernize drive-thrus. A high-profile partnership with IBM (Speedee Labs) tested conversational drive-thru agents that could take orders and confirm combos in natural language. Though that 2021 test had challenges, the strategy underscores McDonald’s approach: custom software at the drive-thru window. More recently, McDonald’s has focused on computer vision to verify orders and ensure accuracy before cars drive off. Cameras scan the pickup area to check, for example, whether a large fry or soda is actually in the bag when handed to the customer – alerting the crew if something is missing.

Underpinning these innovations is cloud and edge computing. McDonald’s teamed with Google Cloud to run AI workloads both in the cloud and on local “edge” servers in each restaurant. For instance, weather data and inventory analytics run in Google’s cloud, feeding recommendations to menu screens in real time. Critical ordering functions (like verifying a transaction) happen locally to avoid delays. Custom software for mobile ordering and payment has also been rolled into the drive-thru workflow. Customers can order via the McDonald’s app and choose drive-thru pickup, further decongesting lines.

Data-Driven Insights

One of the major advantages of investing in custom software is the ability to collect, analyze, and act on data in real-time. McDonald’s leveraged this capability to make smarter operational decisions and improve both efficiency and customer satisfaction:

• Customer Behavior Tracking: Data from mobile apps, self-order kiosks, and drive-thrus reveal peak hours, popular menu items, and repeat customer habits. By analyzing these patterns, McDonald’s can anticipate demand surges and prepare accordingly.

• Menu Optimization: AI and analytics help determine which menu items sell best at specific times of the day, in particular locations, or for different customer segments. This enables McDonald’s to tailor promotions and improve profitability.

• Predictive Inventory Management: By forecasting demand, software reduces food waste and prevents shortages. Real-time alerts let staff adjust preparation to match order volume, ensuring both freshness and availability.

• Marketing Insights: Data-driven insights allow McDonald’s to create targeted promotions based on customer behavior, location, and purchase history. Personalized offers increase customer engagement and boost sales.

• Operational Benchmarking: Location-specific metrics help compare performance across stores, enabling managers to identify best practices and areas for improvement.

By harnessing data, McDonald’s can continuously refine its drive-thru strategy, improving speed, accuracy, and customer satisfaction while making informed decisions at all levels of operations.

Outcomes: Efficiency, Accuracy, and Satisfaction

The results of these tech investments have been tangible. Even before the pandemic, McDonald’s was using “mobile order & pay” in thousands of U.S. locations, shifting about 20% of drive-thru orders to pre-orders. This dramatically shortened lines and reduced errors on large orders. With AI recommendations live, many restaurants reported higher average checks and faster service times. In tests, smart menus and voice AI pushed order accuracy up to 93% (a double-digit improvement) and raised customer satisfaction scores by 12 points. Less-wait times and fewer mistakes mean happier guests and more repeat visits, especially during peak hours when drive-thrus handle the bulk of business.

Moreover, McDonald’s real-time data allows continuous improvement. The company A/B tests different prompts and layouts, measuring impact on sales. Custom analytics dashboards track every drive-thru transaction second-by-second. This data-driven approach – a direct outcome of their software strategy – identifies bottlenecks (like frequent late-night menu changes) and guides future feature updates. Ultimately, McDonald’s has turned the once-manual, analog drive-thru model into a smart digital ecosystem.

Empowering Staff and Operations

Custom software also supports McDonald’s internal teams, ensuring smoother operations and higher efficiency. By integrating technology with employee workflows, McDonald’s empowered staff to perform at their best:

• Employee Scheduling Optimization: AI predicts staffing needs based on historical order data and traffic patterns, ensuring the right number of employees are scheduled during peak hours.

• Task Management Tools: Staff receives real-time instructions for order preparation and kitchen workflow, reducing confusion and errors.

• Training Modules: Integrated tutorials and e-learning platforms allow employees to quickly learn new procedures, technologies, and safety protocols.

• Performance Analytics: Managers can monitor metrics like order speed, accuracy, and customer satisfaction to identify areas for improvement.

• Remote Monitoring and Support: Headquarters can oversee multiple locations, provide instant support, and maintain consistency in service quality across regions.

• Enhanced Communication: Messaging tools and digital dashboards ensure that all staff members stay aligned on priorities and updates, even in high-pressure environments.

By empowering employees with technology, McDonald’s ensured that the operational side of the drive-thru kept pace with customer-facing improvements, resulting in faster, more accurate, and more consistent service.
