For a company built around coffee, keeping milk, breakfast sandwiches and cup lids available in thousands of stores ought to be a routine operational task. At Starbucks, however, those everyday products have become a recurring test of a much larger supply chain. In January 2026, a Reuters investigation described difficulties with supplier coordination, store replenishment and inventory systems at the chain’s U.S. operations, even as its management was working to improve product availability.
The company reported on October 29 that it ended fiscal 2026 with 41,607 company-operated and licensed coffeehouses worldwide. Supplying that network involves several kinds of logistics operating on very different schedules, from the long journey of green coffee beans to the frequent movement of perishable food into individual stores. Those flows explain why a store may have plenty of coffee yet lack another item on its menu.
How Starbucks’ Supply Chain Works
Starbucks purchases green coffee from producing regions around the world and generally maintains control over the purchasing, roasting, packaging and distribution of coffee used in its operations. Its 2025 annual filing describes a network of mostly company-owned roasting facilities, along with leased warehousing and distribution locations and inventory held by third-party warehouse operators. After roasting and packaging, coffee moves through distribution arrangements that supply company-operated and licensed coffeehouses.
The familiar Starbucks name also appears on coffee sold through supermarkets and other retail outlets, but that is a separate channel. Under the Global Coffee Alliance, Nestlé handles distribution of Starbucks packaged coffee products outside the chain’s stores and, in some cases, their roasting and packaging. Packaged coffee on a supermarket shelf may therefore follow a different route from beans used in coffeehouses.
Food, dairy, syrups, cups and lids must be sourced alongside coffee, often under different commercial arrangements and operating constraints. These flows converge at the coffeehouse, where the customer notices when one fails.
Coffee, Fresh Food and Packaging Run on Different Clocks
Green coffee moves across international markets and through roasting and quality-control processes that operate over relatively long planning horizons. Dairy and many ready-to-eat foods face tighter freshness and shelf-life limits, while stores have limited room for extra stock.
Packaging has another set of constraints. A missing lid may stop the sale of an otherwise available beverage, while changes in packaging specifications can complicate supplier coordination and stockholding. Reuters reported that Starbucks executives had discussed around 1,500 cup-and-lid combinations from different vendors in 2023, a useful illustration of the variety involved rather than a verified current SKU count.
These differences matter because an inventory policy that works well for one product may be wasteful or inadequate for another. Delivering extra coffee beans provides a buffer only for coffee demand; it does nothing for an unexpected shortage of fresh milk. Conversely, sending additional sandwiches to a store with insufficient refrigerated storage risks replacing a shortage with unsold food. An effective system must recognize that the cost of holding inventory, the cost of running out and the time available to recover are different across product categories.
What Went Wrong With Store Replenishment
Reuters interviewed current and former employees about Starbucks’ U.S. supply network. They described fragmented supplier relationships, coordination failures at distribution centers, inaccurate store-demand forecasts and outdated ordering systems. Starbucks told Reuters that it was modernizing technology, improving forecasting and making distribution more responsive; the investigation also found disagreement over how quickly those changes were delivering results.
Some of the problems described were historical rather than measures of current network performance. Two former employees told Reuters that in early 2024 fewer than one in three inbound deliveries to Starbucks distribution centers had been unloaded on time and in full. That historical, source-reported figure is no measure of the chain’s current global performance, but illustrates how uncertainty can enter the system before goods reach stores.
Store ordering adds a second layer of uncertainty. When automated recommendations underestimate demand, a store may be unable to satisfy customers even though inventory exists elsewhere in the network. Such errors also highlight the importance of understanding uncertainty in demand forecasts, particularly when demand patterns change faster than ordering systems can respond. When managers respond by ordering more than their limited storage can accommodate, products can accumulate in the wrong place. Reuters reported examples of both shortages and excessive shipments, including perishable food that was eventually donated or discarded. These accounts show how operational failures can move between suppliers, distribution centers and stores rather than staying confined to one location.
What an Abandoned AI Inventory Tool Reveals
Starbucks sought to improve visibility inside stores by introducing an AI-assisted counting tool that used cameras and spatial information to recognize products. More timely stock records could have helped replenishment planners while reducing manual counting. In May 2026, however, Starbucks discontinued the North American program, according to Reuters, after employees had reported misidentified or missing items during counts.
The decision exposed a distinction between counting stock and managing its availability. Even when a system accurately records the number of milk cartons or syrups in a store, replenishment still depends on forecasts, order quantities, supplier capacity, transport schedules and the reliability of deliveries. More accurate information makes those decisions easier to evaluate, but cannot by itself correct a late shipment or a supply plan that consistently underestimates demand.
Ending this application did not mean Starbucks had abandoned AI elsewhere. Starbucks emphasized a consistent counting process; future improvements will also depend on the physical distribution network.
Faster Deliveries Could Change the Trade-Off
Starbucks’ next approach puts greater emphasis on speed. During its July 2026 earnings discussions, management outlined tests of a 24-hour operating model and an expansion of daily deliveries. As Supply Chain Dive reported in August, the ambition is to replenish inventory within 24 hours and place products where they are needed without requiring stores to maintain large backroom stocks.
By the company’s October 29 earnings call, that effort had made substantial progress. CEO Brian Niccol said daily deliveries were reaching close to 90% of Starbucks’ company-operated coffeehouses in North America and described inventory availability as being at an all-time high. The company did not disclose a comparable item-level availability rate or a historical series against which to measure that claim. Its assessment nevertheless suggests that the replenishment problems described earlier in the year were becoming less severe, although it does not establish that individual products are consistently available across the network.
The improvement comes alongside stronger business performance. Starbucks reported a 7.7% increase in U.S. comparable coffeehouse sales in its fiscal fourth quarter, reflecting growth in both transactions and average spending. That result is consistent with a broader operational recovery, although sales growth alone cannot establish how much improved product availability contributed.
The more ambitious replenishment model is still being developed. Niccol said the ability to respond to a replenishment signal within 24 hours was expected to advance over the next six to twelve months. Starbucks was also testing improvements in demand forecasting, ordering accuracy and replenishment cycles, with further technology modernization planned for fiscal 2027. The distinction matters: daily deliveries to a store do not automatically mean that every product can be replenished within a day of demand being identified.
Faster replenishment could reduce the need to hold large buffers in cramped stores and the dependence on longer-range forecasts for fresh products. Yet more frequent replenishment transfers part of the burden upstream: distribution centers may have to process smaller orders more often, suppliers may face shorter response windows, and transport operations may become more demanding.
The expansion of daily delivery is therefore an operational advance, while the full 24-hour replenishment capability remains a work in progress. The company will still need reliable supplier performance, enough inventory at the appropriate distribution points and ordering systems that can respond when actual demand differs from expectations. Fast delivery is an advantage only when the rest of the network can support it consistently.
What Starbucks’ Experience Says About Supply Chain Management
The Starbucks case offers an unusually accessible view of a familiar supply chain problem. Inventory availability is experienced locally, but the decisions that determine it are dispersed across procurement, production, distribution, forecasting and individual stores. A shortfall in one process can undermine the whole service experience.
The company’s coffee purchasing and roasting operations demonstrate how much coordination already exists behind a globally recognizable product. The difficulties reported in its U.S. food, dairy and packaging supply arrangements show why scaling that expertise across an expanding menu is not straightforward. Products with different demand patterns and storage requirements need replenishment policies that reflect those differences rather than a single formula applied to everything.
Other retail and food-service operators face the same trade-off: inventory must be available when customers want it, without creating excessive waste or cost elsewhere. Starbucks’ progress in expanding daily delivery suggests that improvements in the physical distribution network can help address persistent availability problems. Its next challenge is to establish whether faster, more responsive replenishment can sustain those improvements without placing excessive demands on suppliers, distribution centers and transport operations.
