GMDH Streamline vs ReOrder

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.

ReOrder is inventory forecasting and replenishment software for Shopify merchants, turning sales, stock, supplier rules, and cash limits into a ranked buying plan. It estimates demand using recent Shopify orders, refunds, and current inventory, and supports recorded stockout periods and assumptions for new items. Recommendations show their inputs and calculations, and merchants can accept, change, or defer them. An optional cash limit shows which proposed purchases fit the budget and which remain deferred. Approved items can be grouped into supplier purchase-order drafts and exported as CSV for an existing workflow. The current release connects to one Shopify store, supports up to 3,000 product variants, and reads up to 1,000 recent orders; incomplete imports are flagged. Its Shopify access is read-only, and it does not change Shopify records. It also cannot automatically send supplier orders or write inventory back to Shopify. The plan costs $49 per store per month after a guided 14-day trial through private beta. Requesting access does not install the app or start billing.
