Step 1: Create the Component
Add a new Planned Assortment Change
Select:
Type → Listing Change
Enter:
Name (clear and recognizable, typically combining brand/product and listing reference)
Short description (concise but specific detail on the listing, including timing, product scope, and intent)
Save the component
Step 2: Launch the Calculator
Open the calculator for the Listing Change component
Step 3: Define Timing
Set when the product will launch:
Select the start week (the first week the product is available in-store)
Step 4: Select SKUs
Choose the SKU(s) being listed:
Select the existing SKU, which should already exist in the system
If the SKU is not visible:
Contact Growzz support to have the SKU set up and made available before proceeding
Step 5: Complete the Listing Change Calculator Inputs
Coverage
Enter volume-weighted distribution (%) (the % of your total sales base where the product will be listed)
Volume Build
Define how the product scales over time using three linked inputs:
Start week – when the product begins selling
Target weekly run rate – expected weekly sales once fully established
Weeks to maturity – how long it takes to reach that run rate
Growzz will automatically model a ramp from launch to steady-state volume based on these inputs.
Retail Price (RSP)
Uses the price already set for the SKU (price paid by the shopper)
No change typically required
Cost to Retailer (COGS)
Uses the existing cost set for the SKU (price the retailer pays the supplier)
Optional: Link a Replaced SKU (D-List)
If the Listing Change displaces an existing product:
Select the SKU being de-listed
This allows you to:
Reflect the shift within your range
Understand the net impact more clearly
If no SKU is being replaced:
Leave this blank
Optional: Model Cannibalization Within Your Range (Best Practice)
If the Listing Change is expected to reduce sales of other SKUs in your range:
Add an additional calculator
Select the impacted SKU(s)
Enter a negative volume uplift (reduction vs unpromoted base)
In practice:
Often one additional calculator is sufficient
Only model this where it materially impacts your plan
Important:
This is optional
Focus on your own brand and product range only
This helps ensure you are assessing the true net value of the listing.
Step 6: Add Commentary
Use comments to explain:
Strategic intent (e.g. filling a range gap, strengthening assortment)
Expected performance and ramp-up assumptions
Whether the SKU is incremental or replacing existing products
Any supporting evidence (e.g. performance in other retailers)
Risks or dependencies
Step 7: Review Impact
Performance View
Analyze impact by:
SKU
Brand / subcategory / department
Key metrics:
Volume
Sales
Margin
NSV (Net Sales Value – revenue to the supplier from the retailer)
Investment View
Review:
Any associated costs (if applicable)
Total impact
Step 8: Finalize
Close the calculator to:
Save the evaluated Listing Change
Add it to your plan
Include it in reporting
Key Principle
A Listing Change in Growzz should deliver incremental value to both the supplier and the retailer, with a clear understanding of the net impact across your product range, not just the volume of the new listing.
