How do you currently handle purchase orders for your Shopify store?

Curious what workflows merchants are using after Stocky's shutdown — spreadsheets, a separate tool, or just winging it?

EZStock was built specifically to fill that gap: create a PO, email it to your supplier as a PDF, then mark it received to auto-update Shopify inventory. No spreadsheets.

Would love to hear what's been painful about inventory management for product-based stores.
