Macal, a Chilean auction house founded in 1982, enhanced its online presence in 2021. However, the payment and pledge process has caused confusion and friction, leading users to contact support and abandon their participation.
Unlike e-commerce platforms, which generally charge fees for shipping and handling, an auction platform requires users to pay a fee to participate and purchase items.
My Role: Senior UX/Product Designer
I spearheaded the comprehensive redesign of Macal's payment and pledge-taking process, leading the research, problem identification, and definition of the user flow. I facilitated stakeholder alignment and guided the handoff of design to development, resulting in a simpler and more transparent process that enhances customer participation and bidding in the auction, improving the overall user experience.
The initial payment required to participate in an auction is referred to as a "pledge." If a customer successfully purchases a car or real estate, the pledge is deducted from the total payment.
Challenge
• Confusing terminology, especially around pledges and refunds, was not well-explained
• Mandatory pop-ups after login caused users to drop off
• Multi-step journaling was too complex and slowed down the process
• Unclear timelines for payments and refunds increased user frustration
Goal - Make the process more intuitive, transparent, and efficient, reducing support needs while increasing the number of completed pledges.
Research & Discovery
• Conducted interviews with the customer support team to identify user challenges in the purchasing process and understand operational constraints.
• Performed a heuristic evaluation to identify unnecessary steps and unclear copy.
• Analyze data on payment method preferences to uncover potential opportunities.
• Reviewed customer feedback on social media to assess the company's trustworthiness and identify any potential concerns.
Old vs. New Journey
Old: Intrusive login, redundant journaling, unclear success/failure feedback
New: Streamlined login, simplified pledge management, clear payment timelines, and separate success/failure pages with actionable next steps
The updated process offers a clear, narrative-driven path that guides users through each stage of the payment to participate in the auction.

Final Design
Handoff
I developed handoff documents for the developers that outlined each screen and provided crucial context for a smooth transition. These documents featured organized user flows and were tailored for mobile, 1366px, and 1920px screen sizes.
I worked closely with the development team, highlighting the significance of a clear design handover. To address the issue that animations are often overlooked, I demonstrated each screen individually to ensure that the intended interactions were effectively communicated.

Key Outcomes & Results
Reduced Customer Support Load
The enhancements significantly reduced the number of calls and support tickets received by the customer support team, resulting in fewer instances of confusion over pledges.

• Collaboration with product, developers, and support teams aligned business needs with user goals.
