RestockRadar: plan Shopify reorders

See which products need attention before you place your next supplier order. RestockRadar groups low-stock items, suggests reorder quantities from recent sales and lead time, and lets you review the inputs. Paid plans add email and Slack alerts; Pro adds supplier purchase-order drafts.

// features

>Sales velocity forecasting

Review average daily sales over 7- and 30-day windows. Reorder calculations use the 30-day average; recent orders and changing demand still need your judgment.

>Smart reorder points

Uses lead time, safety buffer, and order cover to suggest when and how much to order.

>Days of stock left

Estimate stock cover from tracked on-hand units, incoming quantities reported by Shopify, and average daily sales. An estimate is a planning signal, not a guaranteed stockout date.

>Email & Slack alerts

On paid plans, get notified when a product hits its reorder point or stocks out — no dashboard-checking required.

>Manual minimums for new products

Set a minimum for a launch or an item with limited recent sales. Check eligibility and inventory tracking; missing data does not become a confident forecast.

>Supplier PO drafts on Pro

Group items by supplier, review quantities and costs, and export a purchase-order draft to CSV. Creating a draft does not send an order to a supplier.

Example screens with demonstration data. Select a screenshot to enlarge it.

Inspect why an item needs attention. This fictional example includes 10 on hand and 4 incoming units.
Use a manual reorder minimum when recent sales are limited. A shelf cap is a separate limit on suggested quantities.
On Pro, review supplier assignments, on-hand inventory, incoming units and suggested quantities before preparing a draft.
Review quantities and export the draft on Pro. Exporting or marking it sent does not email an order to your supplier.

From a low-stock flag to a supplier draft

Review the reason for a flag, check the proposed quantity, and prepare a draft you can inspect before purchasing.

  1. step_01

    Review stock and demand

    Start with the reorder dashboard. Check sales history, on-hand and incoming stock, and whether the product is eligible for restocking.

  2. step_02

    Check the quantity

    Review lead time, safety days and order cover. Supplier overrides, manual thresholds and shelf caps can change the decision.

  3. step_03

    Prepare the supplier draft

    On Pro, group items by supplier, review the draft and export it. You remain responsible for communicating and placing the order.

// faq

?How is a suggested reorder quantity calculated?
The 30-day average daily sales is multiplied by lead time plus order cover plus safety days. On-hand and incoming units are subtracted, the result rounds up to whole units, and negative results become zero. Supplier settings and shelf caps can affect the result. The worked guide shows an example.
?What if a product is new or has few sales?
Use a manual reorder minimum for a launch or an item with limited sales. A manual minimum sets the reorder trigger; it does not invent demand or guarantee the suggested purchase quantity. Review the no-sales-data bucket and enter a quantity manually when needed.
?How often does inventory refresh?
Free includes daily sync; Starter and Pro include hourly sync. Shopify webhook updates can arrive between scheduled syncs. Check the last sync and the underlying quantities before making a purchase decision.
?How are locations and incoming stock handled?
The app uses Shopify inventory data and incoming quantities where provided. Location-specific stocking policies can cap the suggested quantity for the primary location. It is not a substitute for checking delivery dates, transfers, or supplier commitments.
?Can it send purchase orders to my supplier?
Pro creates supplier-grouped purchase-order drafts and CSV exports. Drafting or exporting does not submit an order to the supplier. Review and send the purchase order through your normal purchasing process.
?Are alerts available on the free plan?
Free includes the dashboard and manual reorder minimums. Email and Slack low-stock alerts are on Starter and Pro. Supplier management, PO drafts, exports and velocity-spike detection are on Pro.
?What should I do about seasonal products?
A recent-sales average cannot predict a seasonal jump by itself. Review your expected demand, manual minimums, lead times and order cover before placing a seasonal order. Exclude products that should not be reordered.
