Jungle Scout Inventory Manager Tutorial for Amazon FBA
In this guide
The quick answer
How do you use Jungle Scout Inventory Manager?
Jungle Scout Inventory Manager helps Amazon FBA sellers estimate when to reorder stock, how many units to buy, what that reorder may cost, and the potential profit connected with it. For useful forecasts, first connect Seller Central and maintain your product costs, lead time, reorder days of supply, and a sales-history window that reflects normal demand.
Inventory planning gets expensive when the inputs are vague. A reorder can tie up thousands of dollars, but waiting too long can leave a good listing out of stock. The value of Jungle Scout's inventory workflow is that it turns your own cost and sales information into a repeatable decision process instead of asking you to reorder by instinct.
The video below is my walkthrough with Ed from Jungle Scout. The core process still holds up: set the product information first, then read the forecast. I have updated the written guide where Jungle Scout's current documentation is more specific than the older recording, especially around sales-history windows and the multi-location feature discussed as a future update in the video.

Start with Product Costs & Settings
Inventory Manager depends on information stored in Product Costs & Settings. After you connect a compatible Amazon Seller Central account, your active products can appear in Jungle Scout. From there you can search by ASIN, SKU, or title, keep products visible or hidden in Jungle Scout, and maintain the cost and logistics inputs used by inventory and profitability calculations.
The official Product Costs & Settings guide keeps the same basic cost structure shown in the video. The important difference is that you should treat every field as an input to a later calculation, not as a box to fill once and forget.
| Input | What it means | Why it matters |
|---|---|---|
| Effective date | The sales period that should use a particular set of costs. | A supplier price change should not rewrite the economics of older sales. |
| COGS per unit | Your labor and material cost to produce one unit. | It feeds the total cost per unit and profit calculations. |
| Shipping cost per unit | The cost of moving the product from production toward Amazon. | Keeping it separate makes freight inflation easier to notice. |
| Miscellaneous cost | Optional per-unit prep, tax, royalty, or other expenses you want included. | Missing recurring costs can make projected profit look stronger than reality. |
| Lead time | Days from placing the supplier order until stock is received and available at Amazon. | It influences the latest date you can reorder before a likely stockout. |
| Reorder days of supply | How many additional days of selling you want the next order to cover. | It helps determine the recommended reorder quantity. |
The video also shows product-level settings for visibility and review requests. That remains relevant: current Jungle Scout documentation lets eligible users skip review requests for selected products, while the exact Review Automation controls depend on the subscription. Keep that setting separate from inventory planning; turning review requests on or off does not change your stock forecast.
Set lead time conservatively, then keep it current
Lead time is more than factory production. Jungle Scout defines it as the days from placing the supplier order until the goods are received and available for sale at Amazon. Include manufacturing, freight, domestic delivery, and realistic Amazon receiving time.
Use a realistic number with room for normal delays, then update it when the process changes. A new factory, slower shipping lane, or peak-season congestion can make last quarter's lead time a poor assumption.
Production
Count the time from purchase order to finished goods, including any packaging or inspection delay you regularly experience.
Transit
Include international and domestic movement, customs, handoffs, and realistic variability rather than only the carrier's best-case estimate.
Amazon receiving
The clock does not stop when the truck arrives. Your lead time should reach the point where the inventory is actually available for sale.
Reorder days of supply answers a different question: once the new order arrives, how many days do you want it to cover? Jungle Scout uses this input with average daily sales to calculate a reorder quantity. A 90-day setting does not mean you must always buy exactly three months of stock; it tells the model the coverage target you want it to use.

Once the inputs are in place, Inventory Manager combines your FBA inventory, inbound inventory, average daily sales, lead time, reorder days of supply, and product costs. The current dashboard can show an inventory status together with the date to reorder, reorder quantity, reorder cost, reorder profit, days remaining, and other inventory-level metrics.
The statuses are designed as a fast signal. Order Now means the forecast expects your lead time to exceed the days of inventory remaining. Reorder Soon puts you close to that point. In Stock indicates more breathing room, while Overstock indicates inventory well above the selected reorder coverage.
| Metric | What it tells you | Useful check |
|---|---|---|
| Date to reorder | The latest suggested order date based on days remaining and lead time. | Has lead time changed since you entered it? |
| Reorder quantity | Average daily sales multiplied by your reorder days of supply. | Does the sales-history window represent likely future demand? |
| Reorder cost | Recommended reorder quantity multiplied by total cost per unit. | Are COGS, shipping, and recurring miscellaneous costs current? |
| Reorder profit | Average profit per unit multiplied by the recommended reorder quantity. | Treat it as an estimate, not money already earned. |
| Days remaining | Inventory plus inbound inventory divided by average daily sales. | Was the product recently out of stock or unusually promoted? |
This is why I would not judge the tool by one attractive profit number. The forecast is a chain. If average daily sales are distorted, the suggested quantity changes. If total cost per unit is incomplete, the reorder cost and profit estimates change. If lead time is too optimistic, the reorder date can become less useful.
Choose the sales-history window that matches the product
The video demonstrates how changing the time frame changes the forecast. Jungle Scout's current documentation is more specific: Inventory Manager lets you choose 15, 30, 60, 90, or 120 days of past sales for the calculation. The selected period is averaged to produce Average Daily Sales, which then affects how quickly the model expects stock to run out and how much it recommends ordering.
A shorter window reacts faster to recent demand but can overreact to a promotion or holiday spike. A longer window smooths movement but can understate current demand after sustained growth.
One correction to the older explanation: a longer time frame is not automatically more accurate. Jungle Scout recommends choosing the period that best represents the sales rate you expect during the period you are ordering for. A recent holiday spike, a long stockout, or a major change in advertising can make either a short or long window misleading.
For example, a 15-day average can stay inflated after a one-week promotion, while a 120-day average can lag after sustained growth. Choose the window that gives the forecast the most representative demand signal.
Check these five things before placing the supplier order
Inventory Manager can structure a large purchase, but review the assumptions before sending money. The dashboard cannot know about every supplier delay, competitor stockout, or upcoming demand event.
- Confirm the current unit economics. Check supplier price, shipping, prep, and recurring per-unit costs against the latest purchase order.
- Review stockouts and promotions. Either can distort Average Daily Sales in opposite directions.
- Update lead time. Ask the supplier what is realistic for this order, not what happened six months ago.
- Check inbound inventory. Avoid ordering as though goods already on the way do not exist.
- Compare the recommendation with cash flow. A forecasted profitable reorder can still be too large for the money your business needs elsewhere.
Reorder Profit is a planning estimate, not guaranteed earnings. Price, fees, advertising, returns, and demand can change, so pair the forecast with your own cash plan and risk tolerance.
What happened to the planned multi-location inventory update?
Near the end of the video, Ed explains that Jungle Scout was working on a way to track inventory beyond Amazon warehouses. That was a future-looking statement in the recording, not a feature promise for every current account.
Current documentation still describes the forecast around Amazon FBA and inbound inventory. It does not confirm general tracking for a garage, 3PL, or every external location. If multi-location inventory is essential, verify it directly before buying a plan for that purpose.
Keep separate records for units held away from Amazon, transfers, purchase orders, and cash committed to stock. Use Inventory Manager where its FBA data is strongest rather than forcing one dashboard to become your entire inventory system.

Jungle Scout Inventory Manager: frequently asked questions
Does Jungle Scout automatically know my product cost?
No. You need to enter and maintain the relevant product costs. Jungle Scout can combine those inputs with Amazon-related expenses it records, but missing or outdated COGS, shipping, or miscellaneous costs can distort the result.
Which sales-history period should I use?
Choose from 15, 30, 60, 90, or 120 days and use the period that best represents the demand you expect during the next ordering cycle. Avoid blindly using the longest period. Promotions, seasonality, stockouts, and recent growth can make different windows more or less representative.
Is Reorder Profit guaranteed profit?
No. It is an estimate based on average profit per unit and the recommended reorder quantity. Your eventual result can change with selling price, fees, advertising, returns, demand, and costs.
Can Jungle Scout track inventory in my garage or 3PL?
The video discussed multi-location inventory as an upcoming idea. The current Inventory Manager documentation reviewed for this guide centers on FBA and inbound inventory, so verify any external-location workflow directly with Jungle Scout before relying on it.
Do I need to connect Amazon Seller Central?
Yes, Inventory Manager relies on connected seller data. Jungle Scout's current setup guidance says to connect Seller Central first, then make sure the relevant ASINs are visible in Product Costs & Settings.
Use Inventory Manager as a decision aid, not autopilot
The best part of Inventory Manager is not the colored status label. It is the discipline of connecting demand, lead time, stock, product cost, and cash before you reorder. When those inputs are maintained, the suggested date, quantity, cost, and profit give you a practical starting point for the supplier conversation.
Before every large order, check the inputs one more time and ask whether the selected sales history represents the next selling period. If the answer is yes, the forecast can help you plan with much more context. If the business has just changed, update the assumptions first. Good inventory planning is less about predicting the future perfectly and more about making the next decision with better information.
