POS Cart Attributes

POS Cart Attributes — Shopify Point of Sale cart & line-item attributes

Capture custom cart-level and line-item attributes at the Point of Sale — no backend required.

Install on Shopify App Store

$4/month · 7-day free trial. Opens the listing so you can install on your store.

What it does

Section titled “What it does”
  • Cart attributes — add order-level key/value pairs from a smart-grid tile (e.g. order reference, customer type).
  • Line-item attributes — add per-product key/value pairs from the cart line-item menu (e.g. warranty ID, custom notes).

Both flows use admin-managed key lists (Shop metafields) so every register shows the same options. Staff pick a key, enter a value, and save.

Pricing

Section titled “Pricing”

POS Cart Attributes is $4/month, with a 7-day free trial. One plan covers cart-level and line-item attributes on every register — no extra backend to maintain.
