ReorderIQ turns messy spreadsheet math into a clear answer: how much to order, and when.
Enter a few numbers for each product — annual demand, order cost, holding cost, and lead time — and ReorderIQ instantly calculates:
• Economic Order Quantity (EOQ): the order size that minimizes your total cost
• Reorder Point: the stock level that tells you it's time to order
• Safety Stock: your buffer against demand swings and shipping delays — calculated simply, or statistically with a target service level
• Estimated stockout and reorder dates, plus a reminder before you run out
Built for Amazon, Etsy, and Shopify sellers, and any small business juggling multiple SKUs. No inventory syncing, no barcode scanning — just the math, done right.
Why ReorderIQ:
- Free to try for 14 days, then a single one-time purchase unlocks everything. No subscription, no ads, no account required.
- Works completely offline. Your numbers never leave your device.
- Unlimited SKUs, no artificial limits.
- Transparent formulas — see exactly how each number was calculated.
Stop guessing when to reorder. Start ordering with the numbers behind you.
