Anvil

Anvil helps growing merchants manage inventory and purchasing in one place. Create and send purchase orders to your suppliers, receive stock against them, and track quantities and costs across all your locations. Anvil watches your sales and tells you what is running low and what to reorder, with reorder points based on each product's sales history. Inventory counts and costs sync back to Shopify automatically. If you are moving off Stocky, Anvil replaces it.
