Leveringsvensters

Leveringsvensters are predefined time intervals during which a supplier, carrier, or logistics provider commits to delivering goods to a customer or recipient. The concept is used in both business-to-business and business-to-consumer contexts to align expectations, plan resources, and reduce the need for multiple delivery attempts.

Windows can vary in width: fixed slots (for example 08:00–12:00), multi-hour windows (e.g., 09:00–18:00), or customer-chosen slots. Some systems offer next-day or same-day windows, while others provide recurring daily or weekly slots. The choice of window width depends on factors such as density of deliveries, vehicle capacity, and urban access restrictions.

Implementation typically relies on order management and routing software, contract terms with carriers, and customer interfaces for selecting windows. Wider windows can lower delivery risk and reduce cost, but provide less predictability for recipients; narrower windows improve service levels but may increase operational complexity and cost. In both B2B and B2C settings, offering delivery windows can reduce failed deliveries, improve planning, and enhance customer satisfaction, while requiring accurate address data, inventory visibility, and reliable real-time tracking.

Common metrics include on-time delivery within the agreed window, window accuracy (delivered within the promised slot), and delivery-promise adherence. Challenges include traffic volatility, weather, access restrictions, and last-mile constraints. Regulatory or contractual terms may specify service levels, penalties for missed windows, and allowances for rescheduling or re-delivery.
