SlotMaster
SlotMaster is dock scheduling software for booking inbound and outbound appointments. Warehouse, distribution, manufacturing, and third-party logistics teams can view appointments by timeline, calendar, or list across docks. Carriers reserve available slots through a public link without creating an account. Each dock can have separate operating hours, slot durations, buffer times, and daily booking limits. Booking statuses run from booked and confirmed through arrival recorded, in progress, completed, cancelled, and no-show. The interface and carrier portal support 14 languages. Higher plans exchange booking data with WMS, TMS, or ERP systems through REST API and webhooks. Data is encrypted in transit and at rest, with row-level organization policies and server-side checks for anonymous bookings. SlotMaster offers assisted pilots with configuration, carrier onboarding templates, training, and a review call. Essentials costs €99 a month; Professional costs €199 a month; Business costs €449 a month. A 10-day trial is available, with no free plan.
