GMDH Streamline

GMDH Streamline is a desktop application for business demand forecasting and inventory replenishment planning. It imports sales and inventory information, generates statistical forecasts, and can create replenishment orders along with demand and revenue plans. Data can come from spreadsheets, ODBC-connected databases, or supported accounting and inventory systems. Listed integrations include SAP, Oracle NetSuite, Microsoft Dynamics, QuickBooks, Odoo, Shopify and Cin7. Bidirectional integrations can send recommended replenishment orders back to a connected system. Streamline Server runs as a Windows service and lets multiple users work simultaneously on one project file. For hosted solutions, the maker says client-server transfers use TLS encryption; passwords are hashed on the server and encrypted over the network. The free edition is limited to annual revenue up to US$ 1M, 1,000 planning items and 10,000 annual sales quantity. Other pricing is customized to customer needs. Mac support starts at macOS 10.14, and the maker notes that its Mac package lacks an Apple-issued certificate. The company is headquartered in New York, New York.

Streamline links forecasting and replenishment planning with a range of data sources and integrations. The free edition has explicit volume limits, and pricing beyond it is customized.

Streamline may suit businesses that need to forecast demand and plan replenishment across inventory items or locations. Its data connections and server option may be useful to teams working with existing systems or shared projects.

GMDH Streamline is demand-forecasting and inventory-replenishment software for businesses coordinating stock across products and locations. It suits teams that can consolidate sales and inventory data and need forecasts connected to ordering decisions. The free edition is a useful entry point for smaller operations, while larger deployments will need a customized arrangement.

Overview

Streamline brings sales and inventory information into a planning workflow, produces statistical forecasts, and turns those forecasts into replenishment orders, demand plans, and revenue plans. That combination is more operational than a forecasting-only application: the intended outcome is deciding what to buy, where to place it, and when to replenish.

The product can work with spreadsheets, databases accessed through ODBC drivers, and supported accounting or inventory-management systems. Integrations listed by the maker include SAP, Oracle NetSuite, Microsoft Dynamics, QuickBooks, Odoo, Shopify, and Cin7. Where a bidirectional connection is supported, recommended replenishment orders can be exported back to the connected system, reducing the gap between a planning recommendation and execution.

Key features

Forecasting tied to stock decisions

Statistical forecasts form the base of the workflow, but Streamline also includes reorder point automation, safety stock planning, multi-location planning, and transfer recommendations. These tools make it a better fit for inventory teams balancing service levels and stock placement than for users who only need a demand chart. Demand and revenue plans add a planning perspective beyond individual purchase recommendations.

Data connections and replenishment exports

Importing from spreadsheets and ODBC-enabled databases gives businesses a route in even when their systems are varied. The named integrations cover major enterprise, accounting, commerce, and inventory platforms. Exporting recommended orders through bidirectional integrations is particularly valuable when planners want the system of record to receive approved actions, although the usefulness of that workflow depends on whether the required connector is supported.

Deployment and security

The product is offered for macOS, Windows, web use, and self-hosted deployment. Streamline Server runs as a Windows service and lets multiple users work simultaneously on the same project file, making it more suitable for shared planning than a single-user desktop setup. For hosted solutions, the maker says data transfers use TLS encryption, while passwords are hashed on the server and encrypted over the network.

There are practical deployment caveats. macOS support starts at version 10.14, and the Mac package is not signed with an Apple-issued certificate, which may require extra attention during installation. For projects above 100,000 SKUs, the recommended server setup is Windows or a virtual machine with a minimum two-core processor running at 3 GHz or faster and 16 GB of RAM.

Pricing

Free Edition

The Free Edition costs nothing. It covers businesses with up to US$ 1M in annual revenue, up to 1,000 planning items (SKUs multiplied by locations), and up to 10,000 annual sales quantity. Those caps make it appropriate for a small operation evaluating forecasting and replenishment planning or running a relatively compact assortment. They are also hard boundaries: a growing catalog, multiple locations, or higher sales volume can push a business beyond the edition even if the workflow itself remains suitable.

Customized pricing

Beyond the free limits, pricing is customized to the customer’s needs. The pricing page invites prospective customers to describe their requirements so a Streamline expert can help choose a solution. This can accommodate larger or more complex deployments, but it prevents a straightforward budget comparison before contacting the company.

Platforms

Streamline supports macOS, Windows, web access, and self-hosted deployment. The Windows-based Streamline Server option is the clearest fit for concurrent work on a shared project file. macOS users should account for the minimum 10.14 requirement and the unsigned package when planning installation.

Who it's for

Streamline is aimed at businesses that need forecasting and replenishment in one process, particularly those managing several locations, safety stock, reorder points, or inter-location transfers. It is also a reasonable starting point for smaller businesses that fit the Free Edition caps and want to connect existing spreadsheets or business systems.

It is less compelling for a company whose needs exceed the free quotas but requires transparent, self-serve pricing, or for a team whose accounting, inventory, or commerce platform is not among the supported integration paths. Very large projects should budget for the stated server resources and a Windows-based service deployment.

Pros and cons

• Pro: Forecasts, replenishment orders, demand plans, and revenue plans share one workflow, so planning can lead directly to inventory action.
• Pro: Reorder point automation, safety stock, multi-location planning, and transfer recommendations address common operational inventory decisions.
• Pro: Spreadsheet, ODBC, and named enterprise and commerce integrations provide several ways to bring data into the system.
• Pro: The free edition gives smaller businesses access without an upfront charge.
• Con: The free edition is limited to US$ 1M in annual revenue, 1,000 planning items, and 10,000 annual sales quantity, so growth can force a plan change.
• Con: Larger deployments require a sales conversation because pricing is customized rather than published.
• Con: The unsigned macOS package can make installation less seamless for Mac users.

Verdict
