Why these guides exist
Most inventory management content is written by agencies or SaaS marketers who have never actually run a product business. The advice is generic, the examples are hypothetical, and the formulas are copy-pasted from Wikipedia.
These guides are different. They were written by Andrew Simpson — who built an £80M ecommerce business, spent £200,000 on enterprise inventory software he could never get his team to use, and then built Canopy because none of the existing tools solved the actual problems Shopify brands face day-to-day.
The weeks cover guide includes the exact formula we used to identify £23,400 in dead stock at Bailey & Coco. The China importing guide covers the exact lead time management approach that stopped the brand from running out of its best-selling collar sizes during peak season. These are real operational playbooks, not SEO articles.
Canopy automates everything these guides teach you to do manually. But whether you use Canopy or not, this content will make your inventory operations tighter.
