The problem
A reorder spreadsheet is right until the week it isn't.
Sales velocity shifts, suppliers slip, a best seller quietly sells out while cash sits in slow movers. By the time a gap shows up in the spreadsheet, the lead time has already run out.
- 01
Best sellers stock out
Demand picks up, the reorder happens on the usual schedule, and the item is gone for the length of a lead time.
- 02
Cash sits on shelves
Slow movers get reordered out of habit. Money that should fund winners is tied up in months of stock.
- 03
Late suppliers go unnoticed
A supplier that used to take 30 days now takes 40. Nothing updates your math, so every order is late.
How it works
Three steps from store data to a purchase order.
- 1
Connect
Install from Shopify. Reorder Radar reads products, stock levels by location, incoming units, unit costs and the last 60 days of orders. Read-only.
- 2
Calculate
Each night, every SKU gets a demand rate (ignoring stockout days), a reorder point from its supplier lead time and safety stock, and a stockout probability.
- 3
Decide
You get a ranked list: what to order today, how many units, by when, and why. Approve a draft PO per supplier and send it.
A decision, not a graph
Every recommendation shows its work.
This is the Product X example from above, explained the way the app explains it:
- 1Selling 10.5 units/day (steady over 90 days); 2 out-of-stock days excluded.
- 211-day lead time → about 116 units will sell before a new order arrives.
- 384 on hand + 20 incoming = 104, which is 12 short of lead-time demand.
- 4Safety stock of 32 units keeps a 95% service level given daily swings of ±4.7 units.
- 5Stock runs out in about 8 days, before an order placed today can arrive. Order 75 units today and ask the supplier about faster shipping.
- 6The quantity brings stock to about 179 units: 14 days of demand (lead time + 3-day order cycle) plus safety stock.
The math, in one screen

What you get
Built around the decisions you actually make.
Order-by dates, not just reorder points
Each SKU shows the day its stock position hits the reorder point, so you can batch orders per supplier instead of reacting to alerts.
Stockout probability
A plain percentage: the chance of running out before an order placed today arrives, from your own demand variability and lead times.
Purchase-order drafts
Grouped by supplier, editable, with MOQ and case-pack rounding, CSV export and a supplier email.
Supplier reliability
Receipt dates on your POs measure on-time rate and real lead times. Late suppliers automatically get longer lead times.
Excess stock and capital
See which SKUs hold more than your overstock threshold and how much cash is tied up at unit cost.
Daily digest email
Only when something needs ordering. Weekly or off if you prefer. Links straight to the draft POs.
Accuracy you can audit
Forecasts are compared with what actually sold, so you can see how right the numbers have been.
Built for
- Shopify stores selling physical products you buy from suppliers
- Roughly 50 to 5,000 active SKUs
- Supplier lead times of a week or more, including imported goods
- Teams that plan reorders in spreadsheets today, or recently lost Stocky
Not a fit (yet)
- Dropshipping, print-on-demand or made-to-order products
- Stores that need bundle or kit component forecasting
- Multi-channel inventory outside Shopify (Amazon, wholesale portals)
- Warehouse management, barcode receiving or POS
Moving off Stocky?
Shopify retired Stocky on August 31, 2026. Reorder Radar covers the planning side: demand forecasting, reorder suggestions, supplier lead times and purchase-order drafts. It doesn't do POS, stocktakes or barcode receiving.

How does Reorder Radar decide when to reorder?
It estimates each SKU's daily demand from your Shopify orders (ignoring days the item was out of stock and netting refunds), multiplies by the supplier lead time, and adds safety stock sized to the service level you choose. When stock plus incoming units fall to that reorder point, it tells you to order, and how many units cover the lead time plus your order cycle.
Is this AI forecasting?
No. It's a statistical method you can check by hand: averages, variability, lead times, and a normal-distribution risk estimate. Every recommendation lists the numbers and the reasons behind it. We think that's more useful than a black box.
What data does the app access?
Read-only access to products, inventory levels, locations and orders. Shopify treats order access as protected data because orders contain customer details, but Reorder Radar only uses order line items: variant, quantity, dates, refunds and cancellations. Its data queries never ask for customer names, emails, phone numbers or addresses, and none are stored (Shopify's order webhooks include them; the app ignores those fields). It can't change anything in your store.
How long until I see recommendations?
The first sync starts as soon as you approve access. Products and stock usually import in minutes; the last 60 days of orders follow. The app shows progress and fills the list in as data arrives. Very large catalogs can take longer.
Do I have to set anything up?
No setup is required to see your first list: stock, sales, incoming units and suppliers (from each product's vendor) come from Shopify. Setting real supplier lead times sharpens the order dates, and the app tells you which suppliers still use the default.
How much order history do I need?
Recommendations appear as soon as sales data syncs. Products with less than about two weeks of in-stock sales are labeled "Not enough sales history" so you know to treat those numbers as estimates. Shopify gives apps the last 60 days of orders by default; seasonality adjustments need 12 months and extended order access.
Does it handle multiple locations, bundles and variants?
Stock is summed across locations and every variant is tracked separately. Bundles are not broken down into components yet, so bundle SKUs are forecast as their own items.
Can it create purchase orders?
It drafts purchase orders grouped by supplier with editable quantities, a CSV export and an email draft you send from your own inbox. You mark each order sent and received. Units on sent POs count as incoming, and receipt dates measure supplier reliability.
How is billing handled?
Through Shopify. Every plan starts with a 14-day free trial. Charges appear on your Shopify invoice, and you can change or cancel your plan from inside the app without contacting anyone.
What happens if I uninstall?
Syncing stops and credentials are deleted immediately. Shopify then sends a data-deletion request for your store, and we delete everything stored for it automatically.
Know what to reorder before you run out.
Install from Shopify, and the first ranked list of products needing attention appears once your store data syncs. No spreadsheets, no setup calls.
