Project Context

iyzico's İşim İçin mobile app serves SME and micro business users to manage their payment and business operations on the go.

Over time, increasing product breadth without clear UX strategy led the app to mirror the web panel rather than deliver a mobile-first, task-oriented tool — which was no longer meeting merchant expectations for speed, clarity, or control.

Problem

The original İşim İçin experience had:

A cluttered home screen with competing information

Critical actions buried deep in navigation

Inconsistent information architecture across features

A perception of "mobile = smaller panel" rather than a complementary tool for daily tasks

This complexity caused:

Higher cognitive load for merchants

Confusion around where and how to perform frequent tasks

Lower engagement on mobile compared to expectations

Goals

The redesign aimed to:

Simplify the mobile experience according to daily merchant workflows

Surface mission-critical actions at the right moment

Improve clarity, control, and trust on mobile

Establish a scalable UX infrastructure that supports future feature growth

Research & Insights

Methods:

User interviews with diverse merchant segments

Analysis of mobile vs panel usage habits

Comparative review of common merchant tasks

Key insights:

Merchants prioritize quick access to main actions rather than deep analytics on mobile

Users want instant context: what's happening now, not everything that might matter

The existing app felt like a replicated panel rather than a mobile experience

Based on these insights, the redesign focused on what matters most in context-aware mobile usage patterns.

Design Approach

Redesign principles guided the solution:

Task prioritization: Show the most frequent actions first

Information clarity: Reduce noise and highlight relevant data

Predictable navigation: Consistent structure tailored for mobile habits

Scalable infrastructure: Prepare the app for future expansions without overwhelming users

This aligns with industry expectations for usable, trust-centric fintech design, where clarity and simplicity outweigh sheer feature density.

Key Design Decisions

1. Merchant-Focused Home Screen

The home screen was rebuilt to show:

Critical status summaries (e.g., payouts, pending actions)

One-touch entry points for payment link creation and transaction tracking

Why? Merchants need fast insight and action routes within seconds — crucial on mobile.

2. Clear Action Hierarchy

Frequently used actions were elevated visually and structurally, while secondary items were de-emphasized or reorganized.

Why? Mobile context calls for minimal cognitive load and immediate task execution.

3. Consistent Navigation Patterns

Tabs and categories were restructured so merchants don't feel "lost" — every function now logically relates to a business goal.

Why? Consistency in navigation reduces friction and improves user confidence.

Flow & Experience

The redesigned flow prioritizes:

First-look critical insights

Quick access to main actions

Logical grouping of related features

Predictable system behavior that reduces hesitation

(UI screens are intentionally omitted due to B2B confidentiality.)

Validation & Outcomes

Since the redesign:

Users complete main actions faster

Home screen comprehension improved significantly

Perception shifted from "panel mimic" to mobile-centric tool

The app's UX structure became flexible for scaling

Early qualitative feedback reflected that users now feel oriented and in control, a key metric in fintech usability.

Learnings & Next Steps

Learnings

Mobile success in B2B fintech comes from doing less but doing it better

Merchant expectations on mobile differ from panel use; answering "what's next?" matters more than showing all data

Prioritization shapes user perception of value

Next Iterations

Personalizing home sections based on merchant segment behavior

Testing contextual smart suggestions (e.g., next recommended action)

My Role & Collaboration

I led the project end-to-end, including:

User research and problem framing

Information architecture and interaction design

UX prioritization with PM and developers

Alignment with business, data, and operations teams

This case reflects my approach to product design: designing with user behavior at the core and measurable product outcomes in focus.

Impact

  • Access time to main actions reduced
  • User comprehension of home screen improved
  • Mobile app perception as "auxiliary tool" strengthened
  • Flexible UX infrastructure created for new features
