Forthcast - 2026 Pricing, Features, Reviews & Alternatives

Forthcast is an inventory management and demand forecasting application for Shopify merchants. The platform merges artificial intelligence driven demand forecasts with automated purchase order creation, replenishment scheduling, and stockout prevention alerts to support optimal inventory levels across product catalogs. It serves growing brands that balance inventory availability with working capital constraints in both single location and multi location fulfillment environments. Forthcast offers unlimited stock keeping unit support at a flat monthly subscription fee regardless of catalog size or sales volume.

The platform employs machine learning models to analyze historical sales records, seasonal cycles, trend trajectories, and external demand signals in order to produce forecasts extending up to twelve months. Forecasts include confidence intervals that enable risk assessment when planning purchases. The replenishment table displays each stock keeping unit alongside current stock, forecasted demand, and recommended reorder quantities. Risk windows for stockouts are calculated by combining inventory positions with supplier lead times and forecasted demand patterns to issue early warnings before depletion. Draft purchase orders are generated automatically from forecast data and can be reviewed, adjusted, and transmitted directly to suppliers through the interface. Scheduled replenishment supports fixed cadence ordering at four-week, eight-week, and thirteen-week intervals, advancing next order dates and calculating quantities that account for minimum order requirements and container shipments. The optimal stock level calculator determines target inventory positions by factoring lead time variability, service level objectives, and carrying cost parameters. An overstock identification module highlights slow moving stock keeping units with excess inventory levels to facilitate promotional actions or order adjustments. Forecast accuracy tracking compares predicted demand against actual sales to provide visibility into model performance and reliability improvements over time.

Forthcast installs as a native application from the Shopify App Store and synchronizes sales history, inventory levels, and product catalog data automatically upon installation. Demand models begin processing immediately and initial forecasts become available within twenty-four hours of activation. Core functionality operates within the Shopify ecosystem through the native application programming interface, eliminating dependencies on external data sources or supplemental software for standard inventory management and forecasting operations. Integrated billing and compatibility with Shopify multi location inventory architecture ensure seamless deployment and operation within merchant workflows.
