Everything for Amazon Sellers—in One Base.

If you are researching how to change SKU in an Amazon listing, the key limitation is that Amazon does not let you rename an existing seller SKU. Create a replacement offer with the desired seller SKU against the same ASIN, then retire the old offer only after its inventory and connected systems are accounted for. For FBA, creating that replacement is not evidence that Amazon has moved the old units to it. ...

An FBA Amazon partnered carrier shipment fee pays for inbound transportation booked through Amazon’s carrier program—not the fulfillment service that picks, packs, and ships customer orders, and not inbound placement. Amazon’s Partner Carrier program guide says transportation is billed directly to the seller account in Seller Central (data checked November 15, 2026). Before disputing a charge, match it to the shipment, distinguish the estimate from the posted transaction, and identify exactly what changed. ...

An Amazon FBA packing slip is not the same as box-content information or an FBA box ID label. A supplier’s paper list can help you check a delivery, but enclosing it does not complete Amazon’s box-content submission or identify each carton with its required box label. A commercial invoice serves a separate trade-document purpose. Does that mean you can always omit a packing slip? Not necessarily. The official sources below establish the separate jobs of box contents, labels, and trade documents; they do not establish a blanket exemption from every packing-list request. Check any instructions attached to your shipment, supplier, or freight arrangement rather than treating “no packing slip” as a universal rule. ...

Closing an Amazon FBA listing does not remove the physical inventory from Amazon’s fulfillment centers. It closes your offer while retaining the listing record for reactivation; deleting changes the seller-account record instead. Neither action is a substitute for arranging the return, disposal, or liquidation of stock you want out of FBA. The useful decision is therefore two decisions: what should happen to the offer, and what should happen to the units? This guide keeps them separate, including the checks to make before deleting a SKU that could receive customer returns or recovered inventory. ...

Amazon FBA bubble wrap prep should protect the complete fragile unit while leaving its product identification scannable on the outside. Amazon’s public prep guide says fragile items, ceramics, and glass should be fully bubble wrapped, with labels outside the wrapping (source checked November 15, 2026). Before dispatch, approve the finished package, not simply the supplier’s promise to use bubble wrap. This guide provides a supplier acceptance workflow for ordinary, dry fragile products. It does not prescribe liquid seals, bag dimensions, or sharp-item protection. The checklist is a reusable inspection tool, not a report of physical drop testing or a guarantee of Amazon acceptance. ...

Amazon FBA sold-as-set labels identify several items that must stay together as one sellable unit, not an entire shipping carton of separate inventory. Amazon’s public prep guide says that items assembled for sale as one unit should be packaged together and clearly marked outside with wording such as “Sold as set” or “This is a set—do not separate” (source checked November 12, 2026). The handling label does not replace the product barcode or physically secure the contents. ...

The Amazon FBA sell through rate compares units shipped over the past 90 days with average inventory held in Amazon fulfillment centers during that period. Sales can rise while the ratio falls if average inventory rises faster. This guide isolates that numerator-and-denominator problem; for the broader inventory score, see the Amazon IPI guide. Amazon’s US Inventory performance help page, checked November 12, 2026, supplies the formula used below. The examples are hypothetical calculations, not results from a real seller account. ...

Amazon FBA does not have a general minimum shipment quantity that forces you to start with hundreds of units, according to Amazon staff explanations checked on November 12, 2026. In an Amazon Seller Forums reply, Dominic_Amazon explains that you could theoretically send one item, while noting that it may not be cost-effective. That answers whether a very small shipment is possible—not whether it is the right test for your product. Supplier minimum order quantities, carton configurations, account capacity, and the cost of getting inventory ready can all affect your decision. ...

Amazon FBA liquid packaging requirements depend on dangerous-goods status, volume, container, and closure—not a blanket rule that every bottle needs the same bag. Amazon’s US liquid-products guidance requires bagging for dangerous-goods liquids regardless of their seal, while non-hazmat liquids follow packaging-specific rules (data checked November 12, 2026). Start with the product’s classification, then choose leak containment and breakage protection separately. This guide focuses on the individual sellable unit. The FBA prep requirements overview covers other product types; the shipping-to-FBA guide covers the shipment around those units. A transport carton is not automatically a substitute for the bottle’s own protective packaging. ...

The Amazon FBA case packed vs individual units decision starts with the actual carton: use a case-pack template when it accurately describes a repeatable single-SKU box. Use the individual-units packing path for mixed-SKU boxes or single-SKU boxes whose packing configuration changes. Choose from the cartons you actually have—not from how the supplier describes the order. Amazon’s Send to Amazon guide, checked on November 12, 2026, defines single-SKU boxes, or case packs, as containing one or more units of the same SKU. It also explains that the individual-units step can apply to mixed-SKU boxes and changing single-SKU boxes. ...

Sponsored Brands image specifications depend on the asset and ad format: Amazon’s current Collections documentation specifies a logo of at least 400 × 400 pixels, no larger than 1MB, in PNG or JPG. The older Product Collection format documents custom images of at least 1200 × 628 pixels, no larger than 5MB, in PNG or JPG—but the newer Collections format does not support custom or lifestyle images. Product images belong to the advertised ASINs and follow listing-image requirements rather than either upload specification. ...

To reconcile Amazon FBA inventory, fix one reporting period and inventory scope, then bridge the Inventory Ledger’s starting warehouse balance to its ending warehouse balance using the movements within that scope. Use the detailed view to explain the remaining difference by event, location, and disposition—not to turn every negative adjustment into a missing-unit claim. This is a period-end quantity workflow, not an inbound shipment investigation or an inventory-report download tutorial. Amazon’s US Inventory Ledger report documentation, data checked 2026-11-10, supplies the field definitions and reporting cadence below. The workflow is based on that public documentation, not operation of a seller account. ...
