Maintaining the right inventory levels is one of the most delicate balancing acts for retail suppliers. Too little inventory can lead to lost sales and reduced customer loyalty. Too much inventory can result in markdowns, increased carrying costs, and even loss of modular space due to weak sell-through.
For suppliers working with Walmart, the Ladder Plan is an important tool designed to help prevent both scenarios. In this article, we’ll look at how a Ladder Plan provides visibility into product flow, sales trends, and forecasting opportunities to help suppliers make smarter supply chain decisions.
What is a Ladder Plan?
A Ladder Plan is a retail planning and analysis tool that tracks how products move through the supply chain from arrival at a distribution center or store to final purchase by the customer.
It enables suppliers to monitor:
-
-
- Inventory levels
- Point-of-sale (POS) performance
- Pricing changes
- Forecast accuracy
- Upcoming events and demand shifts
-
Simply put, the Ladder Plan connects operational data with forward-looking planning.
Why the Ladder Plan Matters for Walmart Suppliers
Walmart holds suppliers to high standards for:
-
-
- In-stock performance
- Cost control
- Replenishment accuracy
- Supply chain efficiency
-
The Ladder Plan helps suppliers meet these expectations by replacing guesswork with data-driven decision-making. When executed properly, a Ladder Plan supports suppliers in:
✅ Forecasting for Future Events
Retail demand fluctuates around promotions, seasonal peaks, and store events. Ladder Plans help suppliers anticipate unit lifts and align production and shipping schedules accordingly.
✅ Internal Supplier Demand Forecasting
The Ladder Plan is used to review the Walmart demand forecast, ordering forecast, and current replenishment levels. This information is vital for the supplier to determine the appropriate manufacturing volumes for the upcoming weeks.
✅ Tracking POS Data
Many Ladder Plan tools integrate directly with POS data, enabling suppliers to respond quickly to real-time sales patterns and demand shifts.
✅ Monitoring Network Activity
Suppliers gain visibility into how quickly products move through Walmart’s network, highlighting slow-moving inventory or potential out-of-stock risks.
✅ Understanding Pricing Decisions
Price reductions and markdown strategies impact sell-through, margins, and replenishment needs. Ladder Plans provide context for these changes.
What Information Is Included in a Ladder Plan?
While formats vary, most Ladder Plans include:
-
-
- Available inventory
- Item numbers (including Walmart item IDs)
- Pricing
- Sales history
- Forecast projections
- Upcoming events
- Production schedules
- Supplier on-hand (OH) inventory
- Shipment and receipt data
-
For many suppliers, the Ladder Plan becomes the central hub for inventory planning.
Building a Walmart Ladder Plan
Each week, Walmart emails suppliers a ladder plan tool and their raw sales and inventory data. Suppliers are responsible for downloading both files and ensuring they work with the latest version of the tool, as templates and formulas may be updated.
Ladder Plans are commonly managed using Microsoft Excel, where embedded formulas assist with calculations and projections.
Step 1: Populate the Data Dump Tab

-
-
- Open the raw data file
- Copy all columns and rows
- Paste into the Data Dump tab
- Begin pasting at cell B2
- Note: Always copy the full dataset. Missing columns can break formulas.

Step 2: Complete the Supplier Flow Tab
Enter the following information:
-
-
-
-
-
- Item numbers
- Supplier on-hand quantities
- Weekly shipment quantities
-
-
-
-
This tab drives inventory movement projections.
Step 3: Fill Out the Event Forecast Tab
-
-
-
-
- Identify promotional or event weeks
- Enter anticipated unit lifts
- Adjust forecasts accordingly
- Accurate event planning reduces stockouts and overstocks.

Step 4: Update the Supplier Receipts Tab
Enter the following information:
-
-
-
-
-
- Units expected to arrive
- Timing by business week
-
-

This ensures inbound inventory aligns with outbound demand.
Step 5: Compile the Ladder Plan
Once you have populated all the tabs, open the Compile tab and click Build Sheet.
The tool consolidates data into a complete Ladder Plan ready for review.
