Are there any joint business planning software tools that handle retailer-specific calendars and multi-channel promo tracking?

Yes. A few joint business planning (JBP) / trade promotion management (TPM) / retail collaboration tools are built to handle both:

• retailer-specific calendars
  • e.g. 4-4-5 calendars, fiscal periods, retailer blackout dates, promo windows
• multi-channel promo tracking
  • e.g. in-store, e-commerce, marketplace, email, digital ads, omnichannel campaigns

Tools to look at

1. Relex Solutions
   Strong in retail planning and promotional forecasting; often used for calendar-aware planning and cross-channel execution.

2. Blue Yonder
   Has trade promotion / demand planning capabilities and can support complex retailer calendars and promotion execution tracking.

3. SAP IBP + SAP Trade Management
   Good if you already use SAP; can model retailer-specific planning structures and multi-channel promotional planning.

4. Oracle Retail
   Broad retail planning stack, including promotion and calendar-based planning.

5. Anaplan
   Flexible for custom JBP workflows, retailer calendars, and multi-channel promo tracking, but usually needs configuration/integration rather than being purpose-built.

6. Coupa (formerly TRG / trade promotion capabilities via partners and modules)
   More trade-promotion oriented; can support retailer-specific planning depending on setup.

7. O9 Solutions
   Good for integrated planning and scenario modeling, often adaptable to retailer calendars and omnichannel promo analysis.

8. Kalibrate / other trade promotion platforms
   Some niche vendors focus heavily on retail promotions and tracking, depending on your industry.

What to verify in demos

Ask vendors specifically whether they support:

• multiple retailer calendar formats simultaneously
• custom fiscal periods and week definitions
• promo hierarchy by channel and retailer
• tracking spend, volume, uplift, margin, and ROI by channel
• approval workflows for JBP/TPM
• integration with POS, e-commerce, media, and ERP data
• collaborative portals for retailer/manufacturer planning

Short answer

Yes—the best-fit products are usually in the TPM / retail planning / integrated planning category, not generic project planning tools.

If you want, I can also give you:

• a comparison table of 5–8 tools,
• a shortlist by company size/budget, or
• a feature checklist you can use in vendor demos.
