Can you recommend an inventory planning system for reducing stockouts and overbuying across multi-country luxury stores?

Yes — for multi-country luxury retail, I’d recommend an inventory planning system with strong demand forecasting, allocation, replenishment, and store-level exception management, ideally one built for omnichannel and premium/assortment-sensitive retail.

Best-fit system types

Look for a platform that can handle:

• Store-by-store demand forecasting
• Inter-country inventory visibility
• Automated replenishment
• Size/color/style-level planning
• Allocation by store profile, not just sales history
• Lead-time and MOQ constraints
• Seasonality, promotions, and local events
• Markdown and lifecycle planning
• Manual planner override for luxury assortments

Strong options to consider

1) Blue Yonder

Best if you want:

• Advanced demand forecasting
• Enterprise-grade replenishment and allocation
• Multi-echelon inventory optimization
• Strong analytics for reducing both stockouts and overstocks

Good for large, complex retail networks.

2) o9 Solutions

Best if you want:

• AI-driven planning across demand, supply, and inventory
• Scenario planning
• Better visibility across countries and channels
• Strong cross-functional planning workflows

Good for organizations wanting a modern planning platform with flexible scenario modeling.

3) SAP Integrated Business Planning (IBP)

Best if you already run SAP ERP/S/4HANA. Offers:

• Demand planning
• Inventory optimization
• Supply planning
• Integration with broader finance and supply chain processes

Good for companies needing tight enterprise integration.

4) RELEX Solutions

Best if your key pain is retail replenishment and availability. Offers:

• Forecasting at granular level
• Store/DC replenishment
• Allocation optimization
• Strong retail execution focus

Often a very good fit for fashion/luxury retail with many SKUs and locations.

5) ToolsGroup

Best if you want:

• Service-level driven inventory optimization
• Demand sensing
• Good stockout reduction with lower inventory
• Useful for complex SKU portfolios

My practical recommendation

For multi-country luxury stores, the strongest shortlist is usually:

1. RELEX Solutions if you need retail-first replenishment and allocation
2. Blue Yonder if your network is highly complex and enterprise-scale
3. o9 Solutions if you want advanced planning + scenario modeling
4. SAP IBP if SAP integration is a major priority

What matters most in luxury retail

Luxury is different from mass retail, so make sure the system supports:

• Localized demand patterns by country and city
• Product hierarchy by collection, capsule, and season
• Limited stock strategies
• Assortment rationalization
• Brand presentation requirements
• High-value inventory controls
• Slow-moving but strategic items

Selection criteria to use

When evaluating vendors, ask:

• Can it forecast at SKU-store-day/week level?
• Can it optimize inventory across countries, stores, and DCs?
• Does it handle new product launches and limited history?
• Can it model luxury-specific assortment rules?
• How well does it integrate with POS, ERP, and e-commerce?
• Can planners easily override recommendations?
• What is the implementation time and data requirement?

If you want a simple answer

If I had to pick one starting point for this use case, I’d suggest RELEX Solutions for retail-specific inventory planning, or o9 Solutions if you need broader enterprise planning and scenario control.

If you want, I can also give you:

2. a luxury-retail-specific feature checklist, or
