Top 10 Best Assortment Planning Software of 2026

o9 Solutions supports assortment planning with a graph-based data model that connects hierarchies, attributes, forecasts, inventory, financial targets, and supplier inputs. That structure helps merchants evaluate range decisions against demand, margin, space, and service tradeoffs in the same environment. Integration depth is a major strength because assortment choices can be aligned with demand planning, supply planning, and S&OP processes instead of managed in isolated workbooks.

o9 Solutions also offers automation and extensibility through APIs, workflow configuration, and data pipeline support, which matters for enterprises with complex system landscapes. Admin teams get governance controls such as RBAC, approval flows, and auditability across planning changes. The tradeoff is implementation complexity, since the broad schema and cross-functional configuration need disciplined data stewardship. o9 Solutions fits retailers and consumer brands that want assortment planning tied directly to enterprise planning operations.

Retail groups with complex category structures and shared data across planning, merchandising, and replenishment are the clearest fit. Blue Yonder Category Management combines category review, assortment decisions, and performance analysis with enterprise data integration and configurable workflows. The data model supports hierarchies, clusters, store attributes, and product relationships that matter for localized assortments. Governance is stronger than many midmarket tools because access can be segmented by role and planning process.

Blue Yonder Category Management works best when assortment planning must feed other retail systems rather than remain in a standalone planning workspace. API and integration depth support broader automation, but setup usually requires more data stewardship and implementation effort than lighter planning products. That tradeoff makes sense for retailers standardizing processes across banners or regions. It is less attractive for small teams that need fast deployment with minimal administration.

Its differentiator is the connection between planning logic and the broader Board enterprise planning stack, with APIs, automation hooks, and integration options that support upstream data ingestion and downstream reporting.
