Best Demand Planning Software

o9 Solutions builds the o9 Digital Brain, an AI-powered enterprise planning and execution platform covering demand planning, integrated business planning, supply chain planning and analytics, revenue growth management, supplier relationship management, merchandise planning and sustainability reporting across more than 30 industries.

Extending planning into revenue growth management and merchandising is the scope decision that distinguishes o9, and it follows a real logic. The commercial team's promotion calendar and the supply team's production plan are the same problem viewed from two ends, and when they live in separate systems a promotion gets approved that the factory cannot supply. Holding both in one model makes that contradiction visible before it is agreed rather than after.

The value claims are stated in an unusually commercial form, with multiple annual value cases above 100 million dollars and an increasing number of transformations above a billion. Those are customer outcome figures rather than prices, and they signal the size of organisation o9 sells to more clearly than a feature list does.

Post-Game Analysis is a newer capability and a sensible one: reviewing what a plan predicted against what actually happened is how forecasting improves, and it is almost always the step a busy planning team drops. Multi-echelon inventory optimisation, machine learning forecasting, a control tower, supplier collaboration and assortment planning complete the o9 Solutions platform, with virtual guided tours published in place of screenshots.

SAP Integrated Business Planning is a cloud supply chain planning solution powered by SAP HANA, combining sales and operations planning, forecasting and demand, response and supply, demand-driven replenishment and inventory planning with analytics, what-if simulation and alerting.

Native integration with the SAP Supply Chain Control Tower is the practical argument, and for an SAP shop it is often decisive. Planning depends entirely on the accuracy of master data, open orders and inventory positions, all of which live in the enterprise resource planning system. Every third-party planning tool has to build and maintain that integration, and the reconciliation problems it creates are a permanent tax. A planning solution from the same vendor removes that particular argument, whatever else it costs.

Being built on SAP HANA has a specific consequence beyond branding. In-memory processing is what allows SAP Integrated Business Planning to run what-if simulation interactively rather than as a batch request, and a planner who can test a scenario in the meeting where the question is asked uses simulation far more often than one who has to schedule a run.

Demand-driven replenishment is worth calling out as a distinct methodology rather than a feature. It positions buffers at decoupling points and replenishes against actual consumption instead of forecast, which is a genuinely different operating model for supply chains where forecast accuracy is poor and volatility is high. Machine learning algorithms support the forecasting side, and the solution is positioned around building a risk-resilient supply chain. Rates are not published.

ToolsGroup's Decion is the always-on decision intelligence platform for supply chain planning, continuously sensing demand and supply signals, weighing risk with probabilistic AI, and steering inventory, pricing and replenishment through agentic execution toward service, margin and growth targets. Customers set the guardrails; the supply chain steers itself.

Decion connects forecasting, inventory, pricing and execution in a single AI-powered environment across six areas: Demand Planning (AI-driven probabilistic forecasting capturing seasonality, promotions and market shifts), Supply Planning (multi-echelon optimization balancing service levels against holding costs), PPMO pricing intelligence (modeling demand elasticity and competitive positioning), Strategic Planning (S&OP, IBP and network design scenario modeling), Supply Chain Visibility (a unified real-time digital twin), and Retail Planning (assortment, allocation, forecasting and replenishment).

Decy, the friendly AI assistant inside ToolsGroup's Decion platform, turns complex supply chain intelligence into simple, guided workflows, surfacing risks, explaining recommendations, supporting scenario analysis, and orchestrating actions across planning and execution. Customer results include an iconic British auto marque raising first-time parts availability across every car category without adding inventory (18% less safety stock), an industrial manufacturer taming 1.4 million SKU-market combinations across 42 locations and 17 ERP systems with a team of just two, and a McDonald's distributor in Central America cutting inventory 7% while shifting from push to pull planning.
