Core capabilities built into ReorderGuard Studio
Most free spreadsheets only multiply average daily sales by average lead days—leaving you out of stock whenever a supplier ships 7 days late during a promo week. ReorderGuard calculates combined demand and lead-time standard deviation per SKU.
Compare the net margin lost during a 14-day stockout (plus Amazon/Meta algorithm rank recovery cost) against bridging 300 units via express air courier at $4.20/unit.
Assign 98% service levels to your top 20% profit-generating SKUs and 88% service levels to slow variants so your warehouse cash works where contribution margin is highest.
Drop your Shopify, Amazon Seller Central, or 3PL inventory CSV directly into your browser. Zero supplier unit costs or SKU velocity metrics ever leave your device.
Zero configuration, zero cloud server dependencies, instant execution.
Paste your 90-day SKU sales export or use our built-in DTC & FBA warehouse presets with landed unit COGS, retail price, and historical supplier transit days.
Slide target in-stock service levels from 85% to 99% and simulate port congestion or 3PL receiving backlogs to see exact safety stock and Reorder Point (ROP) thresholds.
Unlock the full SKU-by-SKU reorder calendar, emergency air-freight bridge calculator, and supplier PO generator for a one-time $19 buyout.

Everything you need to know about privacy, local memory execution, and buyouts.
Because averages ignore variance. If you sell 30 units/day and your factory takes 35 days, ordering at 1,050 units gives you only a 50% chance of staying in stock. Any week where sales jump to 38/day or customs holds your container for 6 extra days causes an immediate stockout. Our calculator factors both daily sales volatility and supplier delay variance.
We compare the monthly working capital and 3PL bin storage cost of your safety stock buffer against the lost contribution margin of a stockout—plus the ad spend required to regain organic search velocity and BSR rank once inventory arrives.
Yes. Carrying a 98% service level across all 200 SKUs wastes cash on slow colors and sizes. Our ABC matrix lets you lock a 98% buffer on your top 15% revenue SKUs while trimming slow-moving variants to 88%.
If your sea container is delayed by 12 days on a SKU earning $22 net contribution per unit at 30 units/day, a 12-day stockout costs $7,920 in lost profit. Air-shipping a 360-unit bridge batch at an extra $4.50/unit costs $1,620—saving $6,300 in net profit.
Never. All calculations run 100% inside your browser tab. You can adjust sliders interactively or load a local CSV export without exposing your supplier pricing or SKU velocity to external servers.
You get unlimited lifetime access to the multi-SKU safety stock & ROP table, ABC service-level optimizer, air-freight bridge vs. stockout loss auditor, and clean CSV/PO export—with zero monthly subscription fees and a 14-day instant refund guarantee.
