Know what to reorder before the shelf is empty.
Every product gets a plain answer — how many days of stock are left and how much to order. One list a week, grouped by vendor, and an alert only when a product crosses your line. Read-only: the app shows the numbers, you place the orders.
What it does
Six things, done properly.
A reorder list every week, grouped by vendor
What will run out, how many days of stock are left and how much to order — by e-mail, in Slack or in Discord, with a CSV for your supplier. Days and quantities are shown as ranges, because sales are a count and not a constant.
Two lines instead of a settings maze
Tell the app when to warn you and when it is critical, in plain days of stock. Know a supplier’s lead time? Give it, for the shop, a vendor or a single pinned product, and those products are judged against it.
Numbers that are not fooled
Days without stock do not make a product look slow. A one-off bulk order is capped. Promo days are recognised and not taken for a trend. A real rise in demand is picked up within days.
Alerts only when it matters
One message when a product crosses your critical line or suddenly sells several times faster — never a message for every change of stock. Plus a morning digest on the days something runs out within a week.
Best and worst of your catalogue
Six short lists from the same sales: what earns the most (margin and sales together), best sellers, highest margin — and overstock, lowest margin, most returned. Margins come from what a unit really sold for, after discounts.
“Why this number?” on every row
Open any product and see the sum: units sold, days on the shelf, the pace, the line it is judged against and how the quantity was worked out. Simple enough to redo by hand — no black box.
Tested on real sales, not on promises
A year of real sales, replayed day by day.
1,357 products of an online retailer, Christmas peak included. One virtual buyer ordered exactly what this app advised; another used the usual spreadsheet rule — average sales × delivery time.
Results on historical data; your store will differ, and the app shows its own accuracy for your store as weeks go by. Test data: Online Retail dataset, UCI Machine Learning Repository (D. Chen, CC BY 4.0).
How it works
The first list in a few minutes.
Install from the Shopify App Store
No account to create. The app reads your products, stock levels and the line items of recent orders — it cannot change anything in your store.
Answer one question
While your stock is being read: under how many days should we warn you, and when is it critical? Everything else has sensible defaults.
Get the first list
See what to reorder right away, pin the products you care about most, and add where the weekly list should go: an e-mail address, a Slack channel or a Discord channel.
Is it for you?
We would rather you know now than after a month.
Works best for
- Stores that hold their own stock and track it in Shopify, with products that sell regularly — from about one a week, best from one a day.
- Catalogues of a hundred to a few thousand products bought from several suppliers: cosmetics, electronics, home goods, food and drink, consumables, gifts.
- Stores with seasonal peaks and sales: the pace follows a real rise in demand within days.
Not a good fit
- One-of-a-kind and made-to-order products: there is nothing to forecast from.
- Dropshipping, print on demand, pre-orders: the stock in Shopify is not a shelf you refill.
- Fashion collections that live one season: last season says little about the next.
- Wholesale with single orders larger than your whole shelf.
- Stores that do not keep stock numbers up to date in Shopify — the advice is only as good as the numbers.
- Bundles and kits whose components Shopify does not decrement.
By design the app never orders or edits anything, does not promise exact forecasts, uses no weather, ad budgets or competitor data, and is not an inventory system or a reporting dashboard: a list is there only if it answers what to buy, what not to buy or what to clear.

Questions
How is the quantity worked out?
Pace = units sold ÷ days the product was actually on the shelf in the window (30 or 60 days), adjusted for a significant recent trend. Days left = stock ÷ pace. A product is on the list when stock plus incoming covers less than your reorder line; the quantity brings it up to your critical line plus the days you buy for. Every row shows this sum with its own numbers.
What did you test it on?
We replayed a full year of real sales of an online retailer day by day — 1,357 products, Christmas peak included. A virtual buyer ordered exactly what the app advised; another used the usual spreadsheet rule, average sales × delivery time. Best sellers were in stock on 95% of days against 85%; slower products had about half as many empty-shelf days. The price is more stock on the shelf: about ten days more at the default settings. Results on historical data — your store will differ. Test data: Online Retail dataset, UCI Machine Learning Repository (D. Chen, CC BY 4.0).
Does it order anything or change my stock?
No. The app has read-only access. It shows the numbers; you place the orders.
Is my customers’ data stored?
No. From orders we keep only which variant was sold, how many and for how much. Names, e-mails, phone numbers and addresses are dropped before an order is even queued.
I have several locations.
Stock is summed across the locations you include. When a product looks fine in total but is empty at one location, the row says so.
My store is new — what do I see on day one?
Stock by location, out-of-stock products and a list of what is at or below your units line (5 by default) — these need no sales history. Days left and order quantities appear product by product as sales come in: a forecast needs at least 3 sales of a product in the last 60 days. The best & worst lists fill up after about a month.
What about seasons and last year?
Shopify gives apps the last 60 days of orders. From the day you install, the app keeps weekly totals for good, so your own seasonality builds up over time. Until then a rise in demand is caught by the recent trend.
What does each plan include?
Free: forecast for your 50 best sellers and 5 pinned products, the weekly list, one e-mail recipient, the top 5 of each best & worst list. Starter $5: up to 500 products, the daily digest and instant alerts by e-mail, 3 e-mail recipients, a supplier lead time, 20 rows per list. Pro $9: every product, 10 recipients with Slack and Discord (lists and alerts in your team chat), lead times per vendor, a live Google Sheet, 50 rows per list. Both paid plans start with 14 free days, billed by Shopify.
How do I stop the e-mails?
Every message has a one-click unsubscribe, and recipients can be removed in the app. Uninstalling deletes everything we hold about your store within 48 hours.
