Current Checkout Flow Overview

Steps in SHEIN's Checkout:

  1. User browses and adds items to cart.
  2. Product reviews and user images help with decisions.
  3. Account creation is required at checkout.
  4. After purchase, confirmation is emailed.
  5. Delivery estimates are vague; tracking is limited.

Pain Points:

No Guest Checkout

First-time users must create an account.

Delivery Uncertainty

Vague shipping timelines and poor tracking.

Visual Overload

Distracting promotions, inconsistent fonts, and lack of design cohesion reduce user trust.

Identified UX Issues

1. No Guest Checkout Option

First-time buyers like Alina are forced to create an account, which adds friction and discourages trial purchases.

2. Vague Delivery Timelines

Unclear estimates (e.g., "Arrives between May 5 - May 13") leave users anxious, especially when timing is critical.

3. Inconsistent Design

Mismatched fonts and cluttered visuals (like aggressive promotions) create a lack of trust in the brand's reliability.

Proposed UX Improvements

1. Guest Checkout Option

Problem

Account creation is a barrier for new users.

Solution

Add a prominent "Checkout as Guest" button.

Benefit

Reduces drop-off by allowing users to test the platform without commitment.

Before Before: No guest checkout
After After: Guest checkout added

2. Improved Delivery Estimate Visibility

Problem

Unclear shipping info causes anxiety.

Solution

Add a "View Full Shipping Timeline" option.

Benefit

Builds trust and sets expectations, especially for time-sensitive orders.

Before Before: Vague shipping timeline
After After: Clear shipping timeline

3. Design Consistency and Simplified UI

Problem

Visual clutter reduces credibility.

Solution

Limit font usage and adjust promo placement.

Result
