Restock Inventory

The Restock Inventory tool provides recommendations on products to restock, suggested replenishment quantities, and ship-by dates. You can customize your restock recommendations by configuring your inputs, such as lead time and case pack quantities. The restock tool helps you keep track of your inventory levels so you can maximize sales by meeting product demand while avoiding overstocking.

Frequently asked questions

How does Amazon generate restock recommendations?

One of the keys to good inventory management is keeping the right amount of inventory in stock. This can be challenging, because the “right amount” varies based on future demand and the cost of carrying too much or too little inventory.

To help you overcome these challenges, Amazon has developed a sophisticated optimization model that calculates a suggested replenishment quantity and ship date for your products. The quantity and date recommendations take into account your variable costs, expected revenue, and estimated future demand. The recommendations are intended to provide you with information you can use to balance the cost of running out of stock (lost sales) vs. the cost of carrying too much inventory (capital costs and storage fees) to help you get the highest return on your inventory investment.

The model relies on your inputs and uses an estimate of future demand to generate a restock recommendation.

What are restock limits? (Updated September 3)

In July, we announced ASIN-level quantity limits for products stored in our fulfilment network. We made this change to ensure we had space for all sellers using Fulfilment by Amazon (FBA) and to meet increased demand going into the holiday season. Today, we are moving from ASIN-level quantity limits to storage-type restock limits so you have more flexibility in how you use the limits allocated to you across your products.

Do I need to follow Amazon’s restock recommendations? (Updated September 3)

The restock recommendations are our best estimate of the quantities to replenish to help you avoid running low on products or going out of stock. However, it is always your decision whether or not to follow our replenishment recommendations. At this time, our recommendations don't take the restock limits into account, so note the Maximum shipment quantity before you create a shipment.

Do I need to send my shipments by the recommended ship date?

These dates are our best estimate of when to send in a shipment to help you avoid running low on products or going out of stock. However, it is always your decision whether or not to follow our recommended ship date.

What is a storage type, and how do I identify the storage types for my products? (Updated September 3)

Storage types in Amazon fulfilment centres are:

  • Standard-size
  • Oversize
  • Hazardous materials

Amazon determines the storage type of your inventory based on the characteristics of the product. You can see the storage type of your products in the Inventory Age report.

Note: Sellers cannot change a product's storage type. Products are not classified by more than one storage type.

Do all products fulfilled by FBA have restock limits? (Updated September 3)

Yes. All products that sellers can send to our fulfilment centres are subject to restock limits under the applicable storage type.

How does Amazon calculate the quantity I can send? (Updated September 3)

We calculate the quantity you can send based on past sales, current inventory levels, and fulfilment centre capacity.

How can I determine how much inventory I can send? (Updated September 3)

You can see your restock limits and maximum shipment quantity in the shipment creation workflow above the storage volume monitor. Please wait until the monitor updates before creating your next shipments, to make sure you don't exceed the limits.

Important: Sending inventory in excess of the maximum shipment quantity is a policy violation and may result in cancellation of non-compliant shipments. The excess inventory in shipments is measured against all outstanding shipping orders, including those pending orders that do not yet appear in the monitor.

How does Amazon calculate the maximum shipment quantity allowed? (Updated September 3)

Your Maximum shipment quantity equals Maximum inventory level allowed minus Utilization quantity.

You can see your restock limits, utilization quantity, and maximum shipment quantity in the shipment creation workflow above the storage volume monitor. Utilization quantity represents your current inventory at Amazon, which counts against your maximum inventory level and helps determine your maximum shipment quantity. It comprises your incoming shipments, inventory pending removals, and reserved inventory. This may or may not match the Inventory supply at Amazon number.

Can I appeal for an increase in my product's restock limit? (Updated September 3)

No, we are not accepting requests to modify restock limits.

How do I create a shipment from the Restock Inventory page?

You can create a shipment by selecting the SKU and clicking the Create shipping plan button. To create a shipping plan for multiple SKUs, check the box to the left of each SKU and then click Create shipping plan.

Make sure you have the right user permissions to create a shipment. You can check and update your user permissions in Seller Central under Settings. Select User Permissions from the drop-down menu, then ensure Inventory Planning has the “view and edit” permission enabled.

How do I adjust my restock settings?

You can fine-tune your restock recommendations by adjusting product-level inputs such as supplier lead time and replenishment frequency. To update these settings for a particular product, click on the drop-down menu in the Action column and select Customize SKU settings to be taken to the SKU Details page. You can also configure your settings in bulk by clicking Product settings at the top right of the Restock Inventory page.

Why do I see an alert displayed at the bottom of the Configure SKU settings page?

Alerts let you know about certain conditions that may affect the relevance of your recommendations. For example: “You do not have the lowest-price offer” displays when there are multiple sellers with offers on a given product and you do not have the current lowest offer price.

How can I provide feedback about the recommendations or the Restock Inventory feature?

We welcome your feedback to help us improve our inventory management tools. Send any feedback by using the Feedback button on the bottom of the Restock Inventory page.

I'd prefer to keep my supplier’s name private. Do I have to enter the supplier’s name?

No. You can enter a nickname or code to represent your suppliers. Doing this will not change the quality of your restock recommendations.

How do I flag ASINs as not replenishable?

You can indicate that a SKU is not replenishable on the Restock Inventory page by clicking View details in the Action column and selecting Hide recommendation. Hiding all SKUs associated with an ASIN will exclude the ASIN from your FBA in-stock rate and estimated FBA lost sales.
