Zimpler - Mobile Payments

Payment flows are unforgiving. Users needed to enter a phone number, verify identity, choose a method, confirm, and recover from edge cases without confusion or hesitation.

• Designed the checkout around a few clear steps: phone number, verification, payment method, confirmation.
• Handled states for invoice authentication, one-click payment, declined payment, budget limits, account history, and saved cards.
• Supported brand guidelines and marketing material as the company’s only designer.

The checkout launched as a lightweight payment option that reduced steps compared with traditional payment methods and gave merchants a simpler conversion path.
