shopify-checkout-lab. Real merchant tickets solved with Shopify Functions. Each one ships with its input query, its merchant settings in a metafield and its tests, and is playable at nicolasmateos.com/#lab running the same source file that lives in the repo.
shopify-b2b-order-portal. A wholesale order form for Shopify B2B that does not need Plus. Access decided by one Liquid condition, catalog prices and volume breaks displayed rather than recalculated, the catalog's quantity rule driving the input, and the whole order sent in a single cart call. Built on Dawn.

Shopify B2B without Plus: what B2B really covers on Basic, Grow and Advanced, where the wall is (three active catalogs, assignment through markets), and what to do when you hit it. In Spanish: Shopify B2B sin Plus.
