Managing inventory is one of the most critical — and often most challenging — aspects of running a successful Amazon FBA business. While many sellers rely on basic methods to estimate their stock levels, these methods often fall short when dealing with seasonal trends, unpredictable sales velocity, and scaling product lines. That’s where Amazon FBA inventory forecasting becomes a game-changer.
In this blog, we’ll guide you step-by-step through creating an advanced FBA inventory forecast plan, using tools and strategies employed by top-performing sellers and expert Amazon marketplace management services like YourSeller. Whether you're just starting out or scaling up, mastering this process will help you avoid stockouts, reduce overstock, and optimize profitability.
Why You Need an Advanced Amazon FBA Inventory Plan
Before diving into the how-to, let’s understand the why.
Basic inventory planning may work in the short term, but as your sales grow or fluctuate seasonally, your forecasting must become more refined. Here's why an advanced FBA inventory plan is vital:
Improves Inventory Turnover: Avoid long-term storage fees by maintaining just enough inventory.
Prepares for Seasonal Surges: Leverage historical data to forecast future spikes in demand.
Optimizes Cash Flow: Free up capital by reducing unnecessary stock.
Boosts FBA Performance Metrics: Better IPI scores, reduced stranded inventory, and improved Buy Box performance.
Step-by-Step Guide: How to Create an Advanced Amazon FBA Inventory Forecast Plan
At YourSeller, we’ve created a powerful yet user-friendly Amazon inventory planning dashboard. It uses your actual Amazon data to generate an accurate sales and inventory forecast. Here’s how to build your advanced plan using this approach.
Step 1: Download Your Sales Data
1. Log in to your Amazon Seller Central account.
2. Navigate to: Business Reports > Detail Page Sales and Traffic.
3. Select these two periods:
The current period from this year (e.g., April 1 to May 31, 2024).
The same period from the previous year (e.g., April 1 to May 31, 2023).

Why This Matters: This allows you to account for seasonality and trends in your Amazon FBA sales forecast.
4. Download both reports and paste them into the “Units Ordered” sheet of our forecasting template:
The previous month’s data goes in the Previous Month column.
Last year’s upcoming date data goes in the Upcoming Month column.
Step 2: Download FBA Inventory Data
Go to Fulfillment > Manage FBA Inventory in Seller Central.
Click Request Download to get your current stock levels.
Paste this data into the Manage FBA Inventory sheet in the template.
Pro Tip: Do this regularly to maintain accurate inventory forecasting for Amazon sellers.
Step 3: Use the Amazon Inventory Planning Dashboard
Our dashboard brings it all together using automated formulas that process your sales and inventory data. Here’s what you’ll see in the FBA Inventory Plan Sheet:
SKU and Units Sold: Displays previous period sales data.
Average Units Sold Per Day: Calculated automatically.
Growth Percent: Enter your estimated growth rate (e.g., 15%).
Forecast Period (in Days): Choose how far ahead you want to plan.
Current Available Units: Pulled from your inventory report.
Current Days of Inventory: Shows how long your current stock will last.
Units Needed for Forecast: Calculates how many units you should send based on your sales velocity and forecast duration.
All of this is designed to streamline your Amazon inventory management process without requiring advanced Excel skills or expensive software.
Final Shipment Plan: Your Data-Driven Replenishment Strategy
Once you enter your sales and inventory data, the final column in the dashboard will reveal how many units you need to ship to Amazon FBA.
This number is not just a guess—it’s based on:
Your current inventory
Average daily sales
Projected growth
Forecast period
This data-driven approach helps you maintain healthy stock levels, meet customer demand, and stay competitive on Amazon.
