Cargoson LoadingCalendar vs SlotMaster

Cargoson LoadingCalendar is dock scheduling software for warehouses, with a self-service portal where carriers can book or cancel loading appointments. Carriers do not need accounts; they verify by email. Warehouse teams can set loading durations, operating hours, dock-specific rules, and reserved time for breaks or maintenance. A live appointment calendar, email notifications, dock utilization statistics, and an audit trail of who changed what and when provide ways to follow activity. The built-in Cargoson TMS integration synchronizes shipment and loading information and supports printing labels, CMRs, and waybills. Paid plans include a REST API for connecting schedules with WMS, TMS, ERP, or gate systems; the maker says this integration is designed for a developer or IT team. Premium costs $99 a month and includes unlimited warehouses, docks, users, carriers, and appointments. There is no free plan, but a 14-day trial includes full feature access and requires no credit card. The product is available on web and API, and is presented for manufacturing, logistics and 3PL, food and beverage, and wholesale and distribution operations.

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.
