What you'll get

Shopify's staff explain five inventory measures with worked examples: turnover, gross margin return on inventory, days of inventory on hand, holding cost and sell-through, which is units sold divided by units received. Shopify sells point-of-sale software that runs these numbers and the examples are retail stores, so if you sell through stores, read sell-through as how much of what you shipped them has sold.

Do this week

Work out sell-through for your last month and days of inventory on hand for your best seller using the page's formulas, and if you have no sales yet, run them on your forecast.
