Live on the Shopify App Store · Free for up to 50 products.
Shopify is retiring Stocky: it left the App Store in February 2026 and stops working on 31 August 2026 — and its min/max forecasting was already removed back in July 2025. If you've been without reliable restock forecasting since then, Brimstock is an easy move. It reads the same sales history you already have and gives you per-product advice from day one.
What it does
Brimstock doesn't use one formula for everything. It learns each product's demand pattern and picks the method that fits.
Several forecasting methods are tested against your own sales history and one is selected per SKU — so slow movers and bestsellers are both handled well.
Tells you when to reorder and how much, sized from real forecast error and your supplier lead time — not guesswork.
Raises reorder points ahead of Black Friday, December and January so you stay stocked in your busiest weeks.
A clear dashboard flags what to reorder now vs. soon, with a one-click filter, CSV export and a draft purchase order.

Why merchants switch
Most Shopify inventory apps focus on syncing stock across sales channels or printing barcodes — forecasting is an afterthought. Brimstock is the opposite: the forecast is the product. It reads your order history, classifies each product's demand pattern — steady, seasonal, intermittent or lumpy — and backtests several forecasting methods to pick the one that predicts your sales best. The result is a reorder point and suggested order quantity you can actually trust, per SKU.
Even the newer, lighter reorder apps mostly just average your last 30 or 60 days of sales. That's fine for a steady bestseller, but it quietly over-orders slow movers and misses seasonal and lumpy demand — exactly the products where getting the quantity wrong costs the most. Brimstock treats an intermittent item differently from a steady one because it measures the difference first, rather than applying one moving average to your whole catalogue.
If you're looking for a Stocky alternative specifically for demand forecasting and reordering, that gap opened in July 2025, when Stocky's min/max forecasting was removed, and it widens on 31 August 2026, when the app is retired for good. Brimstock is built to fill exactly that gap: install it and it works from the sales history already in your store — no Shopify POS Pro subscription, no manual data entry, and no spreadsheets to maintain.

FAQ
Yes — it covers the forecasting and reordering side that Stocky users rely on. Because Stocky's forecasting was removed in July 2025 and the app itself stops working on 31 August 2026, Brimstock is designed to be an easy move: it reads the same sales history you already have in Shopify.
No. Stocky was bundled with Shopify POS Pro; Brimstock works on any Shopify plan and doesn't require POS.
Brimstock reads your order history read-only, and stores no customer personal data. It uses aggregate sales quantities per product to build the forecast.
For each product it classifies the demand pattern, backtests several forecasting methods against your own history, and selects the one that performs best — then calculates a reorder point and suggested order quantity from your lead time, target service level and demand variability.
Most lightweight reorder apps average your last 30 or 60 days of sales and apply that to everything. That works for steady sellers but over-orders slow movers and misses seasonal or lumpy demand. Brimstock measures each product's pattern first and picks a forecasting method to match, so intermittent and seasonal items aren't treated like steady ones. It's deliberately focused on forecasting and reordering — it doesn't do purchase-order receiving, barcode label printing or multi-location transfers, so if you need those a heavier inventory suite is the better fit.
