Inventory planning that keeps up when your Shopify brand scales
The Sunday-night spreadsheet guess that got you to seven figures quietly stops working. We keep your reorder points and safety stock current across Shopify and Amazon so you stop losing your best SKUs during your biggest months.
Connect Shopify or Amazon. Start with a product you know: review its stock, sales and suggested reorder quantity before deciding what to buy. You approve the action.
No credit card required. First forecast in hours, not minutes. A few hundred SKUs usually takes a few hours. A few thousand, or both channels, can take a day or more.
Built for Shopify and Amazon sellers. Support answers within 24 hours on work days.
Real-time sync, built-in forecasting, and a 30-day money-back guarantee. Terms: 30-day money-back · 90-day payback guarantee
Why eyeballing it stops working at scale
Three things change at once as you grow, and the cost of a bad guess compounds instead of adding up.
Velocity climbs
A SKU that sold 40 a month now sells 400. The same 25% forecast miss is 100 units short, not 10.
Lead times stretch
Bigger orders mean longer production runs, ocean freight, and supplier queues. A 21-day lead time becomes 45.
SKU count explodes
Variants, colors, and bundles push you from 30 products in your head to 300 you cannot possibly track by feel.
Two numbers every scaling brand needs
You do not need a forecasting PhD. You need a defensible reorder point and safety stock for every SKU that matters. ReplenishRadar keeps both current for you.
Reorder point
The level that triggers a new order. Stock arrives right as you hit zero, in theory.
Reorder Point = (Average Daily Sales x Lead Time) + Safety Stock
Safety stock
The buffer that absorbs the days your forecast is wrong or your supplier ships late.
Safety Stock = Z x sigma x sqrt(Lead Time)
Everything you need to order to a number
Live reorder points
We redo your order points and your buffer as your sales pace and lead times shift. The number never goes stale between orders.
Real lead time tracking
We read your actual purchase order history and use the real spread of arrival dates, not a number you guessed a year ago, in your safety stock.
Days of cover triage
Sort every SKU by days of cover to see what is on fire now and what is overstocked. Reorder the heroes, discount the dead weight.
Shopify and Amazon in one view
