When connecting your Inventory Planner account to Amazon, you will need a separate connection per region. Then, each country in the region will have a warehouse for FBM, and separate warehouses for each FBA (Amazon) location.

For more information about linking Amazon to Inventory Planner, read our article about connecting your store.


When a listing becomes inactive, Amazon stops returning correct data, which means stock and other information might be out of date if you make changes in Seller Central.

Inactive listings are marked non-visible in Inventory Planner and do not appear in the Replenishment report by default.

Creating shipment plans

When saving a purchase order or warehouse transfer in Inventory Planner to an FBA warehouse, you will have the option to create a shipment plan in your Seller Central account. After saving your purchase order, you'll see the following option to push the purchase order or transfer to Amazon.

You can customize the following options:


Using Inventory Planner's label printing functionality, you can print product or case labels for products being shipped to an FBA warehouse.

If you are printing labels in Inventory Planner, select the Seller option.

  • Seller: The seller labels the items in the inbound shipment when labels are required.

  • Amazon only: Amazon attempts to label the items in the inbound shipment when labels are required. If Amazon determines that it does not have the information required to successfully label an item, that item is not included in the inbound shipment plan.

  • Amazon preferred: Amazon attempts to label the items in the inbound shipment when labels are required. If Amazon determines that it does not have the information required to successfully label an item, that item is included in the inbound shipment plan and the seller must produce a label.

Unless you are enrolled in the FBA Label Service, Seller is the only valid LabelPrepPreference value.

Metrics and other Amazon-only related features

There are a few metrics that can be added as columns when generating a report within Inventory Planner that are specific to Amazon.


All bundles associated with FBA are considered assemblies, since Amazon only carries finished goods/produced bundles.

Competitive Price

For Amazon sellers, the competitive price is pricing for active offer listings based on two pricing models:

  • New Buy Box Price

  • Used Buy Box Price

Order Limit

The order limit metric will reflect the "maximum shipment quantity" from Amazon's restock report in your Seller Central account.

The order limit will be reflected in the 'to order' amount, along with the minimum order quantity and units of measurement amounts.

Platform Variant Fee

The platform variant fee is the fee per unit charged by the connected platform (currently only supported for Amazon connections).

​Platform Fee

The 'platform fee' is the total fee charged by the connected platform for the date range of the report. Platform fees include referral fees, variable closing fees, per item fees, and FBA fees.


Profit/Unit is a forward-looking metric that shows the listed price and current product landed cost. For Amazon sellers, product profit is the competitive price minus the landed cost price minus the estimated platform fee.

If the landing cost is not set, Inventory Planner will use the cost price instead.

Other metrics that may be relevant:​

Profit = Revenue - COGS - Platform Fee

Margin = profit / revenue

Data and API details

FBA stock is updated when Amazon receives an inbound shipment. Inventory Planner uses the _GET_AFN_INVENTORY_DATA_BY_COUNTRY_ report.

The stock is calculated as the stock in Amazon plus stock reserved due to fulfillment center transfers (as they're available for sale). This stock does not include FC Processing stock and stock reserved for customer orders.

Inventory Planner ignores sales orders that have a fulfillment-channel of Amazon and sales-channel of Non-Amazon if the item-status is Unshipped. Such orders are usually removal orders and should not count for replenishment.

Replenishment for FBA can be performed in one of the following ways:

  • Purchase the stock from supplier and ship it directly to the Amazon warehouse. In Inventory Planner, this method is represented by the creation of a purchase order with FBA set as the destination. Such a purchase order can be also be saved as an Amazon inbound shipment.

  • Purchase stock from a supplier, delivered to your own warehouse to be considered as FBM stock. In Inventory Planner, this is a purchase order with the main warehouse set as the destination and does not correspond to anything in Amazon. Once you receive products at your warehouse, you then ship smaller quantities to Amazon. In this case, FBA listings should have shorter lead times and days of stock periods and the replenishment number will reflect how many products should be sent to Amazon. To proceed, create a transfer from FBM to FBA which can also be saved as an Amazon inbound shipment.

  • Purchase stock from your supplier and store in your own warehouse, which is then maintained in a different e-commerce system (for example, Shopify)

Note that Inventory Planner also pulls existing inbound shipments from Amazon and records them as transfers from FBM to FBA.

You can save Inventory Planner purchase orders or transfers as inbound shipments in Amazon. In the purchase order edit screen, choose 'Amazon warehouse' as the destination warehouse:

and make sure the Save in Amazon checkbox located near the Save button on the bottom is marked:

You can also set a shipment name by entering it in the PO# field (in advanced mode). If you leave the field blank, Inventory Planner will use an identifier generated by Amazon for the name.

If UOM (units of measurement) is set for a variant, it will be used as quantity the the case of inbound shipments.


My listings appear in the wrong language/currency

If your listings are shown in the wrong language or currency, go to Account > Settings > Connection settings and verify that the Marketplace ID is correct. It should correspond to your 'home' Amazon country. Country-specific Marketplace IDs can be found here.

If it's wrong, you can change it to the desired Marketplace ID, using the option seen in the example below:

I get an error when attempting to save a purchase order/transfer to Amazon

Error: "Failed to save purchase order: Amazon would split it into XXXX shipments. Please check that you have FBA Inventory Placement Service enabled."

This error is returned if you do not have the inventory placement fee enabled in Amazon, but when prompted to save to Amazon, you select “do not split shipments”.

The setting must be configured in Amazon in order to avoid splitting shipments, otherwise an error is returned.
