Overview
GMDH Streamline is a supply chain planning platform that layers demand forecasting, inventory and supply planning, material requirements planning, and sales & operations planning (S&OP) on top of an existing ERP or inventory system. Rather than replacing the system of record, it pulls historical sales, on-hand stock, open orders, lead times, and bills of materials from the connected ERP, generates statistical and AI-based forecasts, and writes back replenishment suggestions, purchase plans, and transfer recommendations. The product is positioned for distributors, manufacturers, and retailers that have outgrown spreadsheet-based planning but find the native forecasting in their ERP too limited.
The forecasting engine automatically analyzes each item for level, trend, seasonality, and intermittency, selecting a model per SKU and validating it against held-out future periods to limit overfitting. Planners can link new products to the history of comparable items, apply seasonal coefficients, layer in promotions and price effects, and override the statistical baseline manually where business knowledge differs from the model. A forecast-approval workflow lets teams mark SKUs as Approved, Unapproved, or Needs Attention and lock approved values, supporting a consensus process across sales, operations, and finance.
On the supply side, Streamline calculates safety stock, reorder points, and min/max levels, and produces optimized order proposals that account for supplier lead times, minimum order quantities, and group economic order quantity (EOQ) across SKUs sharing a supplier or container. It supports multi-echelon distribution networks with inter-site transfers and in-transit tracking, and uses discrete-event simulation at daily resolution to project inventory positions and purchasing signals across the planning horizon. The platform is available as a cloud service and integrates bidirectionally with a published set of ERP, accounting, inventory, and e-commerce systems, plus generic ODBC database and custom API connections.

Common use cases
- Replacing spreadsheet-based demand planning for distributors and wholesalers
- Generating purchase and replenishment plans on top of an existing ERP
- Forecasting seasonal and intermittent demand across large SKU catalogs
- Running a consensus S&OP process across sales, operations, and finance
- Planning inter-site transfers and multi-warehouse distribution networks
- Driving material requirements planning from demand forecasts and BOMs
- Reducing stockouts and excess inventory while freeing working capital
Strengths & considerations
Strengths
- Forecasting validated against held-out future periods rather than fit to current data, reducing overfitting
- Discrete-event simulation at daily resolution for projecting inventory and purchasing signals
- Group EOQ and per-supplier purchasing signals that coordinate orders across SKUs the ERP would handle item-by-item
- Published bidirectional connectors to a broad set of ERP, accounting, inventory, and e-commerce systems plus generic ODBC/API
- Sits on top of the ERP as a planning layer rather than requiring replacement of the system of record
Considerations
- Planning layer only — it forecasts and recommends but relies on the connected ERP as the system of record for transactions
- Reviewers note dashboard customization is limited compared to dedicated BI tools
- Some reviewers report the desktop client license being tied to a physical machine, limiting remote/roaming use
- Deep value depends on quality of historical data and connector setup, which requires implementation effort
- No publicly verifiable security certifications (e.g., SOC 2, ISO 27001) listed on the vendor site at time of research

How is Streamline priced?
Pricing is subscription-based and quoted on request, with tiers scaling by number of users, features, and deployment. The vendor does not publish list prices. A free get-started option is available.
What kinds of forecasting does it handle?
It automatically selects a model per SKU based on level, trend, seasonality, and intermittency, supports new-product and promotional forecasting, and validates models against held-out future periods to limit overfitting. Planners can override the statistical baseline and run a forecast-approval workflow.
Who is Streamline aimed at?
Distributors, manufacturers, and retailers across SMB to enterprise that need demand forecasting, inventory/supply planning, MRP, and S&OP beyond what native ERP planning provides.
