Small Shopify apps for order limits, barcode labels and the EU guarantee notice

Each app does one job inside Shopify's own checkout, admin or theme editor, and each one has a free plan. Questions go to [email protected]. We reply within one business day.

See the three apps
Shopify checkout with the message: Wholesale orders need at least 5 items from this collection. The cart has 3 items, total $1,829.95
Order Limits at a real Shopify checkout: the rule needs 5 items from one collection, so checkout stops the order.
