Handcrafted in Spain

Wholesale portal for Émolo, a handmade jewelry brand from Murcia, built on top of its existing Prestige theme. Access is decided by a single Liquid predicate on customer.b2b? that every price, stock badge and buy button reads, so a guest or a customer without a company never receives a price in the HTML. Buyers can still hide their own prices on screen: the toggle lives in localStorage and is applied in the head, before first paint.

The ordering table is rendered in Liquid and driven by a custom element, one row per variant with live stock. Its steppers are seeded once from /cart.js and kept in step through the theme's cart:change event, so a variant shows the same quantity on the product page, in every collection card and in search results. Submitting sends a single /cart/update.js call with absolute quantities: a first order, a top-up and a reduction are the same request, and a rejected line leaves the cart untouched. Around it: per-variant galleries from a metafield, a grid and list view switch, SKU search that marks the matching row, stock status on each cart line, and a pageshow handler that re-reads the cart when the browser restores the page from bfcache.

Timeless jewelry, Menorca 1998

Wholesale store for Vidal & Vidal, a Menorcan jewelry house, on Shopify Plus. The B2B theme started as a straight export of the consumer Sleek theme with no B2B logic in it, so the first job was clearing 29 orphaned templates inherited from the export. Seven of them referenced videos that only exist on the consumer store and broke shopify theme dev; removing them cut the templates folder by 75%.

The ordering table is a port of the Émolo one to a different theme: same logic, with an adapter layer that swaps Prestige's cart events for Sleek's pub/sub and section bundling, and the same network contract as Sleek's native quick order list, so the cart drawer and header update with no extra code. Each row shows stock, the wholesale price next to the retail price from a variant-level money metafield, and a colour swatch resolved from a metaobject. Only the rows that changed are sent to /cart/update.js, as absolute quantities, flagged as XHR so Shopify validates inventory. The running total is formatted from a Liquid money sample, so it matches the session currency in every market. Purchase is closed to anyone who is not a wholesale customer.

Wellness backed by science

B2B ordering portal for IVB Wellness Lab, a Spanish supplements lab stocked in more than 3,000 pharmacies, built on the Enterprise theme from the brand's Figma designs. Pharmacies buy on volume tiers, so tier logic runs through header, product page and cart: the buyer's current tier sits in the nav, and the next tier is worked out in Liquid from a store-level metafield config, so the client changes thresholds without a theme release.

The product page carries a multi-variant order table whose rows can also be sibling products linked through a metafield, with per-variant galleries and a totals footer, and it keeps the dependent sections in sync when a row changes variant. Product badges and colour schemes are metaobjects that the theme turns into markup and CSS classes, so merchandising stays in the admin. Purchase is locked to company accounts, collections open in a list view built for reordering, discount badges round down the same way everywhere, retail price comes from a metafield, and the cart offers promotional material through a pop-up when the buyer goes to pay.
