GMDH Streamline vs Inventory Planner

GMDH Streamline is a desktop application for demand forecasting and inventory replenishment planning. It imports sales and inventory data from spreadsheets, ODBC-connected databases, and supported accounting or inventory systems, then generates statistical forecasts and can produce replenishment orders, demand plans, and revenue plans. Listed integrations include SAP, Oracle NetSuite, Microsoft Dynamics, QuickBooks, Odoo, Shopify, and Cin7; bidirectional connections can return recommended replenishment orders to connected systems. Planning tools include reorder point automation, safety stock planning, multi-location planning, and transfer recommendations. The free edition costs nothing and is limited to US$ 1M in annual revenue, 1,000 planning items, and 10,000 annual sales quantity. Customized pricing is also available, with no price listed. Streamline supports macOS from version 10.14, though its Mac package is not signed with an Apple-issued certificate. Streamline Server runs as a Windows service for multiple users sharing a project file. Hosted data transfers use TLS encryption, and passwords are hashed on the server and encrypted over the network.

Inventory Planner helps retailers, ecommerce brands, wholesalers, and discrete manufacturers forecast demand and decide what inventory to purchase. Its configurable models cover seasonal, non-seasonal, retail, and wholesale products, with automatic adjustments to sales patterns. For new products, forecasts can use sales data from similar items. Purchasing features include supplier management, minimum order quantities, and open-to-buy budgeting. The service recommends purchases and warehouse transfers across multiple locations, with a customizable forecast horizon and no stated SKU limit. Native integrations include Shopify, BigCommerce, Amazon, eBay, Brightpearl, Cin7, QuickBooks, and other sales, management, fulfillment, and accounting systems. Beta Stock Orders and Reports APIs provide real-time account data, but cannot accept product or variant data. It runs on the web and through an API. Pricing is on request; guided implementation and training are required.
