Apparel inventory is uniquely painful: every style explodes into a size and color matrix, seasons force hard sell-through deadlines, and returns flow back into stock. These five inventory tools handle fashion's specific problems best for Shopify merchants.

The Top 5

Stocky (Shopify): free with Shopify POS; solid purchase orders and demand forecasting for single-location brands starting out.
Inventory Planner: the forecasting specialist. Buy recommendations by variant, sell-through and aging reports built for seasonal apparel.
Cin7 Core: full inventory plus light manufacturing for brands producing their own lines across channels.
Katana: clean manufacturing-focused option for made-to-order and small-batch fashion labels.
Sellbrite: multichannel sync for merchants listing the same apparel on Shopify, Amazon, and eBay without oversell.

The Fashion-Specific Criteria

Judge any tool on four axes: variant-level forecasting (style-level is useless when only size M sells out), returns-to-stock handling, seasonal reporting (sell-through by week, aging by collection), and PO workflows matched to your suppliers' lead times.

Inventory Meets Conversion

Inventory and conversion tools compound: try-on analytics show which products shoppers want (tried-on counts) before purchase data confirms it, giving your buyer an earlier demand signal. And fewer sizing returns means cleaner stock levels to plan against.
