01 / The Challenge

More choices shouldn't mean more friction.

NORTHLINE sells hydration systems with choices of size, color, lid and optional filtration before cart and checkout. The commerce experience must make product choices, accessories, delivery and payment decisions feel straightforward without overwhelming the customer.

05 / Returning Customers

Recognize the customer. Reduce the work.

Saved payment and address information are designed to reduce repetitive input without creating a different checkout architecture. Returning customers use the same familiar flow, with less information to enter.

  • Saved payment
  • Saved billing address
  • Same checkout architecture

06 / Post-purchase

Conversion first. Account creation second.

Account creation is intentionally offered after conversion rather than being required before purchase. This keeps the checkout path lightweight while still giving customers a clear path to save details for future orders.

  • Conversion-first approach
  • Optional account creation
  • Lightweight checkout path

07 / Mobile

A recomposed mobile experience.

The mobile experience is intentionally recomposed rather than simply scaling down desktop layouts. The concept pairs touch-friendly controls with a collapsible summary on Payment and an expanded final summary on Review, plus wallet checkout from Cart.

  • Touch-friendly controls
  • Collapsible order summary
  • Mobile wallet checkout
  • Full-width primary actions
  • Final order summary expanded before purchase
