InventoryOwl

Nightly sync turns your sales history into reorder alerts and dead-stock discount suggestions. One slow mover can quietly tie up thousands in cash while your bestsellers run out. InventoryOwl syncs your orders and inventory nightly, then answers two questions: what needs reordering now, and what to discount. Reorder points and order quantities come from your actual sales velocity, lead times, and safety stock. Slow movers and dead stock are flagged with the cash tied up in each and a suggested markdown. Set lead times and case packs once per vendor. Built for small stores.

This app's listing is still live, but it recently dropped out of Shopify's App Store search index.
