I built a free inventory + purchase order app for Shopify — barcode scanning from your phone

I'm a solo dev and I just shipped EZStock, an inventory management app for Shopify stores.

What it does:

Scan barcodes to count stock — with a handheld scanner or your phone camera (no extra hardware)

Create PDF purchase orders and email them to suppliers in one click

Set reorder points + see how many days of stock you have left before you sell out

Mark a PO received and your Shopify inventory updates automatically

Every new install gets full access to all features free for 14 days, no credit card. After that, there's a genuinely useful free plan (5 POs/month, unlimited products and suppliers), so you're never forced onto a paid tier. Built it because Shopify's built-in inventory tooling is thin and most alternatives are enterprise-priced.

Would love feedback from anyone running a store: https://apps.shopify.com/ezstock
