About the PopUp ‑ Sell by Weight
PopUp adds weight-based selling to Shopify POS for market vendors who need to sell products by weight. This app solves the problem of running two separate systems by letting you mix weight-based items and flat-price products in the same cart at your point of sale.
The catalog is stored directly on your device, so it opens instantly with no data delays and works offline. You don't need to maintain Shopify inventory for your market items – the simple catalog works alongside your existing store products. Price calculates automatically when you weigh items at checkout.
Perfect for seasonal vendors, you can pause the app between market seasons without losing any catalog data. When you return, everything is waiting exactly as you left it. No more manual reconciliation or managing multiple logins across different platforms.
