Project overview
The previous Iuvenis Lab website presented supplements but did not offer a complete purchase journey. The brand needed a store whose catalog, product descriptions and orders could be managed in house. We built a new Medusa and Next.js storefront with seven products in the catalog, a cart, checkout, Paynow integration, courier delivery and an InPost parcel locker option. The owner can edit product content in the admin panel.
The challenge
The store needed to combine the brand's knowledge led identity with a clear path to purchase, while preventing incomplete product information from reaching live sales. The owner also needed direct control over content.
From website to store
The previous site displayed the offer but lacked a full path from catalog and cart to order and payment.
Required product information
Supplement product pages needed clear space for ingredients, directions and required information before purchase.
Independent editing
The owner must be able to update product descriptions and information in the admin panel without a code deployment.
Checkout and delivery
The purchase journey had to connect online payment, delivery selection and order confirmation in one coherent experience.
Our solution
We built a new storefront and a back office for managing the offer. We connected the catalog, cart, payments and delivery in one purchase journey.
A new catalog and product pages
We designed the home page, collection and product pages around Iuvenis Lab's identity. The catalog contains seven supplements. Product pages have space for ingredients, directions and information required before purchase.
Cart and checkout
We prepared a journey from product selection through order details, delivery and payment confirmation. Customers see the order summary and choices they need to make before buying.
Payments and delivery
We prepared Paynow payment integration, including BLIK, and two delivery options: courier shipping and InPost parcel locker selection.
Content control for the owner
We moved product descriptions into the Medusa admin panel so the owner can update the offer without a code deployment. The store includes a safeguard against selling products with missing mandatory information.
Ready for handover
We added order confirmation emails, consent based analytics and error monitoring. We documented the steps for launch on the brand's infrastructure: payment and delivery accounts, domain and complete product details.
