Content about selling on Amazon through Fulfillment by Amazon, including FBA-specific inventory, logistics, and operational strategies.
TL;DR You cannot reduce lead time until you measure it honestly: every day from sending the PO to units going live at FBA. Map all six stages, time each one from your last few orders, then attack the slowest stage first. In my experience, most sellers find two to three weeks of recoverable time hiding […]
TL;DR Your Inventory Performance Index is Amazon’s 0 to 1,000 score for how efficiently you run FBA inventory. It blends excess inventory, sell-through rate, stranded inventory, and in-stock rate. Stay above 400 and you keep unrestricted storage. Drop below and Amazon caps your capacity, usually right before peak season. You find out your storage got […]
TL;DR For Amazon sellers, cycle counting for ecommerce is not walking the aisles with a scanner. Amazon holds most of your stock, so your version is reconciling Amazon’s inventory reports on a schedule, catching lost or damaged units early, and physically counting only the stock you hold yourself. Do both, and your records stay accurate […]
TL;DR Amazon’s aged inventory surcharge, formerly called the long-term storage fee or LTSF, now starts at day 181 and escalates through eight age tiers. The January 2026 update raised the per-unit minimum on inventory older than 365 days from $0.15 up to $0.30 or $0.35 depending on age. If you are searching for “Amazon LTSF” […]
TL;DR ABC analysis for FBA ranks your Amazon SKUs by contribution to the business and groups them into three classes so each one gets a different inventory policy. A items get protection: high service levels, tighter buffers, weekly review, and bulk inventory staged in AWD or a 3PL when needed. B items get balance: standard […]
TL;DR Amazon FBA excess inventory is stock that stopped earning its keep. In most cases, that happens once a SKU passes 180 days without meaningful sales. You have four exit paths for Amazon FBA overstock: discount, liquidate, remove, or dispose. Prevention beats all four. Every Amazon FBA seller eventually finds some FBA excess inventory sitting […]
TL;DR Amazon FBA inventory turnover measures how often you sell through your stock in a given period. Most FBA sellers should target 6 to 12 turns per year, depending on product category. Faster turnover means lower storage costs, better cash flow, and a stronger Inventory Performance Index score. If you’ve ever looked at your FBA […]
TL;DR Economic order quantity (EOQ) is the order size that minimizes the total cost of ordering and holding inventory. For Amazon FBA sellers, a standard EOQ calculation needs adjustment for FBA storage fees, aged inventory surcharges, and inbound placement costs. Getting this right means fewer wasted dollars sitting on warehouse shelves and fewer emergency reorders […]
TL;DR The reorder point formula tells you exactly when to place your next purchase order so inventory arrives before you stock out. The formula: (Average Daily Sales × Lead Time in Days) + Safety Stock. For most Amazon FBA sellers, the tricky part is getting accurate inputs, especially lead time, which needs to include FBA […]
You’ve done everything right. Your supplier shipped on time, your freight forwarder hit the delivery window, and Amazon checked in your inventory without delays. Then out of nowhere, demand on your best-selling ASIN doubles for two weeks. Maybe a competitor went out of stock. Maybe an influencer mentioned your product. Doesn’t matter. You’re out of […]
