Qwikr.store

A business problem
worth solving.

A business selling through a storefront, marketplaces and a physical till can end up with several systems holding different versions of its stock. Wholesale, subscriptions and fulfilment add more moving parts. Qwikr.store is built around a shared catalogue and stock model so these channels can participate in the same operation.

The connected solution.

A multi-tenant commerce platform spanning ecommerce, wholesale, subscriptions, point of sale and other commerce workflows. It includes product variants, bundles, configurators, orders, inventory, supplier processes, retention tools and integration surfaces. A storefront can be delivered separately from the application, with live stock fetched through the platform.

The decisions behind
the experience.

The platform separates tenant operations from the central control plane, with per-tenant databases. The catalogue and order model provide shared context across the ways a merchant sells. Vue interfaces and mobile applications sit over API-backed operations. Integration jobs and webhooks connect external providers without making the storefront depend on rendering the full application for every visit.

Design for the customer, the merchant and the operation.

The documented designer brief distinguishes customer storefronts, merchant tools, operational staff interfaces, platform administration and mobile experiences. A shopper completing a checkout, a member of staff handling a till and a merchant reviewing stock have different priorities. The specification describes those surfaces against one shared commerce platform rather than assuming one interface can do every job.

The model also accounts for merchants using different combinations of commerce capabilities. Catalogue, orders, customers and stock remain connected, while each interface exposes the relevant actions. That separation lets the product support different operating contexts without treating each one as an unrelated application.

Available stock is not simply the stock on a shelf.

The stock-reservation service calculates availability after accounting for active holds. It identifies the inventory target for a product or variant, removes expired reservations, counts competing holds and rejects a requested quantity when the remaining tracked stock is insufficient. Replacing one basket line must not incorrectly release the inventory consumed by another variant in the same basket.

Reservation writes run inside a tenant database transaction. The parent product is locked before a variant because variants can share physical inventory. A reservation has an expiry, and untracked inventory follows a separate path. These details are what turn a stock display into an operational rule that can survive concurrent customer activity.

One catalogue has to remain one catalogue under pressure.

The repository distinguishes feature coverage from launch certification and documents release checks for the commerce core. It includes tenant-isolation coverage and a separate database-engine check because an in-memory test database cannot reproduce every production constraint. Storefront and checkout journeys also need to be checked in the deployed storefront context, not just at the application origin.

The practical lesson is to test where each responsibility lives: tenant access in the application, stock rules in the shared service, external updates at the integration boundary, and customer journeys in the storefront. A good-looking checkout is only one part of that system.
