Supermú is a neighbourhood supermarket chain in Medellín's Área Metropolitana selling online with flat COP 8,000 delivery. We rebranded and migrated the Shopify store, then built the integration layer between the store and the SIESA ERP.

The challenge

Online grocery is one of the hardest e-commerce categories to run. The SKU count runs to thousands, the stock is perishable, delivery has windows, and shoppers expect to pay what they pay in the aisle. Many items sell as packs and as units, some are priced by weight, and stock is held per store.

The program started with a rebrand. The home brand moved from La Vaquita to Supermú, which meant a new store design and a domain migration to supermu.com without losing search rankings or breaking links. Then came the harder question: how to keep thousands of prices, discounts and stock levels in the store in step with the ERP that runs the supermarkets, without staff retyping any of it.

What we built

We redesigned the Shopify store for the Supermú brand, migrated it to supermu.com with redirects in place and search preserved, and ran the SEO work around the migration. The flat COP 8,000 delivery fee for the Área Metropolitana remains the main purchase incentive and the buyer sees it early.

The integration layer came next. MarketIQ Light, our middleware, syncs inventory, prices and discounts between the SIESA ERP and Shopify over a secure WireGuard link into the client's network, with a scheduler, an API and an operations UI so the team can see what synced and what did not. Picker, a React PWA used by store staff, takes online orders through picking and packing on the shop floor. A customer-matching service reconciles Shopify customers with ERP records, and a Salesforce integration carries the customer lifecycle.

Packs versus units, weight-based items and per-store stock are handled in the middleware rather than in the theme, so the storefront stays a plain Shopify store.

The operator note

Grocery runs on a different trust than retail. The buyer wants to know the order will arrive, the produce will be fresh and the price matches the shelf. Those signals have to sit in the UX without over-designing a category that should feel ordinary and familiar. You only know where to draw that line if you have shopped for groceries in Colombia, and we have.

The lesson from the integration work is that the ERP is the source of truth and the store is a view of it. A price or a stock level corrected by hand in Shopify is overwritten on the next sync, so the business rules live in the middleware and nowhere else. A flat fee means a small order costs as much to deliver as a big one. Supermú took that on to keep the offer simple.
