What it is

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.

GMDH Streamline in depth

Read the full write-up

Overview

GMDH Streamline is demand-forecasting and inventory-replenishment software for businesses that need to connect forecasts with stock decisions. It suits teams planning across products or locations and willing to work with a desktop application or server deployment. Its strongest case is the joined-up planning workflow; the free edition’s caps and the Mac package’s unsigned status deserve attention before adoption.

Streamline turns sales and inventory data into statistical forecasts, replenishment orders, and demand and revenue plans. That makes it more operationally focused than a forecasting tool alone, while its usefulness depends on whether its supported connections and deployment fit the business.

For a broader category comparison, see Replenishment Software.

Key features

Forecasts tied to stock decisions

Streamline imports sales and inventory information and generates statistical forecasts. It can also create replenishment orders, demand plans, and revenue plans. Reorder point automation and safety stock planning support routine stock decisions; multi-location planning and transfer recommendations make it relevant to businesses coordinating inventory between sites. This breadth is useful when forecasting needs to lead directly to replenishment, but businesses seeking forecasting without inventory planning may not need the wider workflow.

Data connections and replenishment exports

Inputs can come from spreadsheets, databases accessed through ODBC drivers, and supported accounting or inventory systems. Integrations include SAP, Oracle NetSuite, Microsoft Dynamics, QuickBooks, Odoo, Shopify, and Cin7. Bidirectional integrations can export recommended replenishment orders back to the connected system, which can reduce the gap between a plan and its execution. The practical fit depends on whether a business’s particular system is supported.

Shared projects and hosted security

Streamline Server runs as a Windows service and lets multiple users work simultaneously on the same project file. For hosted solutions, the maker says data transfers between client and server use TLS encryption, while passwords are hashed on the server and encrypted over the network. The recommended server setup is Windows on a virtual machine with a minimum 3+ GHz two-core processor; 16 GB RAM is recommended for projects above 100,000 SKUs. That guidance matters to larger deployments planning infrastructure, rather than to teams using the desktop application alone.

Pricing

Free Edition

The Free Edition costs free. It allows up to US$ 1M in Annual Revenue, up to 1000 Planning Items (SKUs × Locations), and up to 10,000 Annual Sales Quantity. Those thresholds give smaller businesses room to try the planning workflow without a subscription price, but all three caps can constrain use; a business exceeding any of them should consider the customized option instead.

Customized pricing

Customized pricing is based on the customer’s needs, with no fixed price. It is the route for businesses whose scale or requirements exceed the free edition, but the cost must be established with the company. The pricing page invites customers to describe their needs so a Streamline expert can help choose a solution.

Platforms

Streamline is available for macOS, Windows, web, and self-hosted deployment. macOS support starts at version 10.14, but the maker’s guide says the Mac package is not signed with an Apple-issued certificate. That signing note may be a deciding factor for organizations with strict software-installation policies. Windows is also the basis of Streamline Server, the option for simultaneous work on one project file.

Who it's for

Streamline is aimed at businesses that need demand forecasts alongside inventory replenishment planning. It is a particularly plausible fit for teams managing multiple locations, balancing safety stock, or turning recommendations into orders through connected systems. Smaller businesses can start within the free edition’s revenue, item, and sales-quantity ceilings. Businesses that need more capacity should weigh customized pricing against their requirements, while Mac users should account for the unsigned package.

Pros and cons

Pros: Statistical forecasts feed into replenishment orders and demand and revenue plans, connecting analysis to inventory actions.

Pros: Reorder-point automation, safety-stock planning, multi-location planning, and transfer recommendations cover several practical inventory decisions.

Pros: Spreadsheet, ODBC, and named business-system connections provide multiple ways to bring data in; bidirectional integrations can return replenishment recommendations.

Cons: The free edition has three separate scale limits, so growing businesses may need to move to customized pricing.

Cons: The Mac package is not signed with an Apple-issued certificate, which may complicate adoption in managed environments.

Cons: Shared simultaneous work requires Streamline Server, a Windows service, and larger projects have substantial recommended server memory.

Alternatives

Consider eTurns TrackStock if you want a paid stockroom plan with unlimited users, items, and suppliers: Replenish — stockroom costs $40 a month, billed semi-annually, and the product has a free trial. Choose Streamline instead if its forecasting and planning workflow, or its free edition, is the better fit.

Flowlity is worth considering when a paid web or API option with a defined monthly entry plan suits you: Flowlity Lite costs €249 a month, has no long-term commitment, supports up to 5,000 SKUs, and uses CSV upload without ERP integration. It also offers a free trial.

Optiply may suit buyers looking for a paid option with a free trial and published entry plans, including Optiply Lite at €79 a month for up to 1,000 sales orders per month and up to 1,000 SKUs.

Oracle Yard Management is another paid option, with Android, iOS, and web platforms.

Prediko offers a $49 a month Starter plan for stores up to $100K in revenue and has a free trial; consider it when that stated store-revenue tier matches your needs.

Stockagile Replenishment has a paid Starter plan at €49 a month for one store, one user, one register, and up to €10,000/month in sales. Its Android, API, iOS, and web platform coverage may suit a buyer seeking those channels.

ReOrder is a web option for a single Shopify store, priced at $49 a month per store after a 14-day guided trial. Consider it if that Shopify-specific scope fits better than Streamline’s broader planning workflow.

LEAFIO AI Replenishment Software is another alternative, with custom pricing and a demo-and-quote approach.

Verdict

Choose GMDH Streamline if your business needs statistical forecasting connected to replenishment planning, particularly across locations, and its integrations and deployment options fit your operation. The free edition is a useful entry point within its three caps; beyond them, customized pricing is the main trade-off. Look elsewhere if you need a signed Mac package or a fixed price before engaging with the vendor.

Verdict

Streamline combines forecasting with replenishment planning and connections to several business systems. Check the free-edition limits and Mac signing note against your requirements before choosing it.
