The problem

Buying Decisions Without Data Are the Most Expensive Mistakes in E-Commerce

Most Amazon sellers are making reorder decisions based on gut feel, last month’s numbers, or a spreadsheet that’s already out of date. The cost of getting it wrong compounds fast.

Stockouts Kill Ranking

Running out of stock doesn’t just cost you today’s sales. Amazon demotes out-of-stock listings in search results and it can take weeks to recover your ranking after you replenish — compounding the original loss.

Overordering Locks Up Capital

Buying too much ties up working capital in slow-moving inventory, accumulates FBA storage fees, and risks aged inventory surcharges. Cash that’s sitting on a warehouse shelf can’t grow your business.

Lead Times Are a Moving Target

Supplier lead times change constantly. A reorder that would have arrived in 14 days last quarter might take 28 days today. Without a system that accounts for this dynamically, you’re always flying blind.

Manual PO Building Wastes Hours

Pulling data from Amazon, cross-referencing spreadsheets, calculating reorder quantities per supplier, and building purchase orders manually is a full-time job — and it still produces errors that cost money.

How it works

Forecast-Driven. Supplier-Aware. Always Actionable.

From the moment your data syncs, Inventory Optimizer is calculating what needs to be ordered — and by when — across your entire catalog.

Step 1 — Sync

Sync live data from Amazon

Your Amazon inventory levels, FBA quantities, FBM stock, inbound shipments, and sales history sync automatically from Seller Central — always current, always accurate.

Inbound shipments
Sales history

Step 2 — Forecast

Forecast demand across your catalog

The system runs a demand forecast across all SKUs using 7, 30, 90, 180, and 365-day sales data, daily sales rate, and seasonality signals to build the most accurate picture of future demand.

Step 3 — Generate

Generate supplier-organized PO suggestions

Suggested POs are automatically created per supplier — with recommended quantities, recommended order dates, and expected receive dates calculated for you. No manual work required.

The inventory timeline

Inventory Optimizer Knows Where Every SKU Is in Its Lifecycle

Every product has a predictable lifecycle from restock to stockout. The system calculates exactly where your SKUs are — and flags the ones that need action now.

Restocked

FBA inventory arrives. Projected days in stock is calculated from daily sales rate — your coverage window starts now.

Well Stocked

Recommended Order Date

System calculates when you should place your next PO, factoring in supplier lead time so stock arrives before you run out.

Action Required

Low Stock Alert

Amazon flags low_stock. Inventory Optimizer surfaces the SKU in the PO builder immediately — no manual monitoring needed.

Restock Now

Projected OOS Date

The system predicts exactly when stock will hit zero based on current sales velocity — so you can act before it happens.

Critical

PO Placed in Time

With Inventory Optimizer, you place the order before it's critical — every time. Stock arrives, the cycle resets, and you never miss a sale.

Order Quantities Calculated From Your Actual Sales Patterns

The system doesn’t use industry averages or generic benchmarks. Every quantity recommendation comes from your own sales history, run through a demand forecast that accounts for velocity trends and seasonality.

Multi-Period Velocity Analysis — Sales data across 7, 30, 90, 180, and 365-day windows prevents over-reliance on any single period’s anomalies.
Daily Sales Rate Precision — Days-of-supply calculations use your actual daily sales rate — so a SKU selling 10 units/day is treated very differently from one selling 1/day.
Safety Stock Recommendations — The system recommends a safety stock buffer per SKU so you always have a cushion against demand spikes or supplier delays.
Projected OOS Date — For every SKU, you can see the exact date the system predicts stock will reach zero if no order is placed — so you always know the urgency of each reorder.
Forecast vs. Purchase Qty — The grid shows both the Forecast Recommended Qty and the Purchase Qty you’ve set, so you can see at a glance how your order compares to what’s needed.

Amazon's Own Inventory Signals, Built Right Into Your PO Workflow

Inventory Optimizer doesn’t just use your internal stock data — it surfaces Amazon’s native inventory alerts alongside every SKU, so you’re always working with the complete picture.

Low Stock Alerts — When Amazon flags a SKU as low_stock, it’s immediately highlighted in the Custom PO builder so you know exactly which products need attention right now.
Out of Stock Flags — SKUs flagged out_of_stock by Amazon are surfaced at the top of your recommended reorder queue — the most urgent items are always visible first.
Inbound Pipeline Visibility — See Inbound Working, FC Processing, and FC Customer Order quantities for every SKU so you never double-order for stock that’s already on its way.
Unfulfillable Stock — Unfulfillable FBA inventory is tracked separately so it doesn’t inflate your available stock count and cause under-ordering.
Days Left to Order — A calculated countdown per SKU showing how many days remain before you must place a PO to avoid stockout — your action deadline, made visible.

For amazon agencies

Make Stockout Prevention a Service You Deliver

Managing replenishment for a single brand is powerful. Managing it for a portfolio of clients — with complete data visibility and automated PO suggestions per account — is how agencies scale without adding headcount.

Customizable Day Thresholds — Set your own Minimum and Maximum Days Until Stockout. Start with recommended defaults (7 & 30 days) or dial in values that match your supply chain reality.
Automatic Pause Rules — Choose to pause ads when SKUs hit High Risk only, or be more conservative and pause at Moderate Risk too.
Automatic Enable Rules — Decide whether to re-enable ads the moment products are Well Stocked, or hold off until Moderate Risk has cleared too.
Global or Per-SKU Overrides — Apply automation globally across your catalog, then fine-tune exceptions for seasonal items, hero products, or slow movers.
Always Adjustable — Your business changes. Your ad rules can too. Tweak thresholds anytime without disrupting running campaigns.
