The two-part setup

Once PopUp is installed, it’s time to build your catalog. There are two parts that work together: PopUp Admin (your phone browser or computer) — where you manage your product catalog: add products, set prices, assign categories, and customize your product tiles. Do these updates before market day. Shopify POS (your phone, in the POS app) — where you sell. You open the PopUp tile, find a product, enter the weight or quantity, and add it to the cart. The sale goes through Shopify as a custom sale.

On market day

Here’s what a typical sale looks like:
  1. Open the Shopify POS app on your phone
  2. Tap the PopUp tile on the POS home screen
  3. Find your product — browse by category or search by name
  4. For weight-based items: Enter the weight on the keypad
  5. Tap Add to Cart — PopUp calculates the price automatically
  6. Continue adding items, then check out through Shopify POS as normal
The whole process takes a few seconds per item once you’re set up.

Weight vs. fixed-price products

Weight products — you enter the weight at the time of sale. PopUp multiplies weight × price to get the line item total. Supports lbs, oz, kg, and g. Fixed-price (item) products — tap to add to the cart at the set price. Good for pre-packaged goods or add-ons with a set price. You can mix both types in the same transaction.

Sync

Whenever you save a product or category in the Shopify Admin, PopUp syncs your catalog automatically. You can also trigger a manual sync from a desktop via Settings → Sync Now before heading to market.
