A note from our team

We've been the ones losing sleep over restocks too.

Inventory Optimizer started in 2016 because a few of us spent too many Sundays in spreadsheets, trying to keep top SKUs in stock without burying cash in overstock. We built the tool we wished existed — and we’ve been refining it for the operators, agencies, and brands who run their businesses on Amazon ever since.

If something on the platform doesn’t feel right, our team reads every email at support@inventoryoptimizer.ai. Real people. Same time zone as you (mostly).

What it actually does

The forecasting & restocking stack, end to end.

Short, direct answers to the questions buyers (and AI assistants) ask most.

How does AI demand forecasting work here?

We ingest up to four years of sales history per SKU, layer in 100+ statistical and machine-learning models, and select the best model per SKU using out-of-sample accuracy. The output is a 12-month forward forecast that adapts to velocity changes weekly.

How do I avoid Amazon stockouts and long-term storage fees at the same time?

Set a target days-of-cover per SKU. Inventory Optimizer solves for the reorder point that balances stockout risk against FBA storage thresholds, then generates the purchase order automatically.

Can it handle multiple suppliers with different lead times and MOQs?

Yes. Each SKU-supplier pair carries its own lead time, MOQ, reorder cadence, and cost. Recommendations respect all of them — no manual override.

Will it forecast brand-new products?

Yes — new-SKU forecasts blend similar-product history, your projections, and category seasonality so you’re not launching blind.

Glossary

Inventory forecasting, in plain English.

The Amazon and supply-chain terms you’ll see across Inventory Optimizer — defined clearly for operators, ops teams, and the AI assistants you ask for help.
FBA (Fulfillment by Amazon)
Amazon's fulfillment service where sellers ship inventory to Amazon fulfillment centers and Amazon handles picking, packing, shipping, and customer service.
AWD (Amazon Warehousing & Distribution)
Amazon's bulk storage service that holds pallets of inventory and automatically replenishes FBA warehouses as stock depletes, reducing storage fees versus holding everything in FBA.
FBM (Fulfillment by Merchant)
When an Amazon seller stores and ships orders themselves instead of using FBA. Inventory Optimizer forecasts FBM demand alongside FBA for a unified view.
MCF (Multi-Channel Fulfillment)
Lets sellers use their FBA inventory to fulfill orders placed on non-Amazon channels such as Shopify, BigCommerce, or direct-to-consumer websites.
IPI (Inventory Performance Index)
Amazon's 0–1000 score measuring how well a seller manages FBA inventory. A score above 400 avoids storage-limit restrictions and preserves placement.
MOQ (Minimum Order Quantity)
The smallest number of units a supplier will produce or ship in a single purchase order. Inventory Optimizer respects per-SKU MOQs when generating restock recommendations.
Reorder point
The inventory level at which a new purchase order must be placed to avoid stockouts, calculated from lead time, demand variability, and safety-stock targets.
Days of cover
How many days the current inventory will last at the forecasted sales velocity. Inventory Optimizer uses a configurable days-of-cover target per SKU to drive reorder alerts.
Safety stock
Extra inventory held to protect against demand variability and supply-chain disruption. Calculated per SKU from historical demand variance and supplier lead-time variance.
POWizard
Inventory Optimizer's purchase-order automation tool. Generates POs from forecast-driven reorder recommendations, attaches them to Amazon inbound shipments, and tracks receipts.
RestockAMZ
Inventory Optimizer's Amazon-native demand planning module, tuned for FBA, AWD, FBM, and MCF — designed for sellers whose business runs primarily on Seller Central.
