What are the best platforms for integrating demand planning with ERP systems?

Hey G2 community. What are the best platforms for integrating demand planning with ERP systems? If you’ve used SAP IBP, Oracle Fusion Cloud Demand Management, IBM Planning Analytics, Netstock, or Slim4, I’d love to hear which integrations worked best, what was hardest, and what you’d choose again.

1. SAP Integrated Business Planning: SAP IBP is a cloud-native demand planning suite designed for global operations. It integrates tightly with SAP ERP/S4HANA and supports collaborative forecasting, inventory, and S&OP so multinational teams can plan on a single data model with shared master data and governance.
2. Oracle Fusion Cloud Demand Management: Oracle’s cloud demand management connects natively with Oracle Fusion Cloud ERP. It streamlines forecasting and collaboration with embedded best-practice processes and mobile access, helping organizations sense, predict, and shape demand while keeping plans synchronized with upstream ERP modules.
3. IBM Planning Analytics: IBM Planning Analytics offers configurable demand and supply planning models with scenario/what-if analysis and collaboration. It integrates with ERP data to align forecasts and plans across levels (from product families down to SKU when needed), supporting governed, enterprise rollouts.
4. Netstock: Netstock is a cloud demand and inventory planning platform widely paired with many ERPs. Reviewers highlight faster rollouts and time savings for distributed teams, with integrations that help improve fill rates and reduce excess inventory across regions.
5. Slim4: Slim4 is a cloud demand management solution focused on forecasting, sensing, and multi-channel planning. It integrates with ERP systems to provide end-to-end visibility and exception-based workflows—useful for global teams standardizing processes across countries.
