One bulk pool.
Every size in sync.

Stock by Measure is a Shopify app for stores that keep products in bulk and sell them by the ounce, pound, litre, yard, square foot or pack. Set your stock once; every size's count looks after itself.

One pool, every size

Stock a product once, in bulk, and sell it in any size. Every sale, return or recount updates every size at that location.

Any measure, metric or imperial

Count, weight, volume, length and area. Mix ounces with pounds, or grams with kilograms, in one product.

MAXIMUM or BALANCED

Show the most you could sell of every size, or share stock evenly so every size stays available.

Every location

Each location keeps its own stock, with lot numbers, expiry dates and a full history of changes.

Low-stock and back-in-stock emails

A daily low-stock email for you, and a Notify me form that tells shoppers when a sold-out size returns.

Stock on your product pages

An optional panel shows shoppers each location's stock and how many of each size are left.
