GMDH Streamline

Overview

GMDH Streamline is a desktop application for businesses that need to turn sales and inventory data into demand forecasts and replenishment plans. It suits inventory teams that want forecasting connected to reorder decisions; the free edition is a useful starting point, but its revenue, item and sales-quantity caps may rule it out for larger operations.

Streamline can produce statistical forecasts, replenishment orders, and demand and revenue plans from imported data. Its combination of planning capabilities and several deployment options is a strength, provided its supported connections and Windows-based server requirements fit the business.

Key features

Forecasts tied to inventory decisions

Streamline imports sales and inventory information to generate statistical forecasts, then supports decisions through replenishment orders and demand and revenue plans. Reorder point automation, safety stock planning, multi-location planning and transfer recommendations make it relevant to teams managing stock across locations, rather than businesses looking only for a standalone forecast.

Connections and replenishment exports

Data can be imported from spreadsheets, ODBC-connected databases, and supported accounting or inventory systems. Listed integrations include SAP, Oracle NetSuite, Microsoft Dynamics, QuickBooks, Odoo, Shopify and Cin7. Where an integration is bidirectional, recommended replenishment orders can be exported back to the connected system. That can connect planning with execution, though the fit depends on whether Streamline supports the systems a business uses.

Shared project work

Streamline Server is a Windows service that lets multiple users work simultaneously on the same project file. The maker says hosted solutions use TLS to protect client-server data transfers, and passwords are hashed on the server and encrypted over the network. For projects above 100,000 SKUs, the recommended server setup includes Windows, a virtual machine with a minimum two-core 3+ GHz processor, and 16 GB of RAM; that is a meaningful infrastructure requirement for larger deployments.

Pricing

Streamline uses a freemium model. The Free Edition costs free and covers up to US$ 1M in Annual Revenue, up to 1000 Planning Items (SKUs × Locations), and up to 10,000 Annual Sales Quantity. Those caps make it a practical entry point for smaller operations that fall within all three limits, but not a free tier to assume will scale with a growing business.

The Customized pricing plan has custom pricing based on customer needs. It is the option for organizations whose requirements exceed the Free Edition limits or need a tailored solution. The company invites customers to describe their needs so a Streamline expert can help choose a solution.

Platforms

Streamline supports macOS, Windows, web and self-hosted deployment. macOS support starts with version 10.14, but the Mac package is not signed with an Apple-issued certificate, a caveat for users who require signed software packages. Streamline Server runs as a Windows service, so teams considering shared project work should account for that platform requirement.

Who it's for

Streamline is aimed at businesses planning demand and inventory replenishment, especially those that need statistical forecasts alongside reorder points, safety stock, multi-location planning or transfer recommendations. It is a stronger fit when the business can use its data connections and wants recommendations linked to replenishment orders. It is less suitable for teams whose systems are unsupported, whose project environment cannot accommodate Windows Server, or whose revenue, planning-item count or annual sales quantity exceeds the free caps and does not justify customized pricing.

Pros and cons

• Pros: Forecasting connects to replenishment orders and demand and revenue plans, so planning can support operational decisions rather than stop at projections.
• Pros: Spreadsheet, ODBC and named business-system connections give teams several ways to bring data in; bidirectional integrations can return recommended orders to connected systems.
• Pros: Multi-user work on one project file and hosted transfer protections support shared planning workflows.
• Cons: The Free Edition is bounded by three separate thresholds—annual revenue, planning items and annual sales quantity—so a business must fit all of them.
• Cons: Streamline Server is Windows-based, and the recommended setup for projects above 100,000 SKUs calls for substantial memory and processor capacity.
• Cons: The Mac package lacks an Apple-issued signing certificate, which may complicate adoption for users who require signed packages.

Alternatives

Replenishment Software is the broader category to explore when comparing options. Consider Retalon Price Management and Optimization if you want a paid, web-based alternative with pricing available by demo request. Blue Ridge Replenishment Optimization is another paid web option, with a demo available by contacting Blue Ridge. buffers.ai is a paid web-based alternative.

eTurns TrackStock is worth considering for mobile access on Android or iOS as well as web: its Replenish — stockroom plan costs $40 a month, billed billed semi-annually, and includes unlimited users, items and suppliers. It has a free trial but no free plan. LEAFIO AI Replenishment Software, pacemaker.ai Replenishment Decision Intelligence, Slimstock Slim4 and Demandsoft Replenishment Solutions (PRIME One) are paid web-based alternatives.

Verdict

Choose GMDH Streamline if your business needs demand forecasts connected to replenishment planning, can work with its supported data connections, and can meet its deployment requirements. Its key advantage is the link between forecasts and inventory actions; look elsewhere if the Free Edition caps are too restrictive, you need a signed Mac package, or a Windows server does not suit your environment.
