iyzico Business Card - Corporate Card Management Experience

In the iyzico Business Card project, I managed the card application and management process end-to-end (brainstorming → flow design → UI → post-launch improvements) for corporate customers' employees.

The goal was to transform a manual, operations-dependent, and non-scalable process into a completely self-service experience while increasing control and confidence for legal representatives.

Problem Definition

The card allocation process for employees at our corporate customers: - Progressed manually - Depended on the operations team - Was slow with high error risk - Wasn't transparent for legal representatives

Through their own panel, legal representatives couldn't: - Add employees - Define roles - Directly initiate card applications

This situation both weakened user experience and increased operational costs.

Goals

- Automate the card application process end-to-end - Provide legal representatives with a self-service management area - Reduce the operations team's manual workload - Make multi-user & card structure simple and understandable - Create a scalable card management experience for corporate customers

Process & Approach (End-to-End)

1. Brainstorming & Problem Framework

In the project's initial phase, together with the product manager, I involved: - Operations - Backend & Frontend - QA

teams in the process and mapped out the current manual flow on a whiteboard.

At this stage, we produced clear answers to: - Where is the user getting stuck? - At which steps does operations intervene? - What are the risky areas for automation?

This work ensured the entire team viewed the same problem from the same framework.

2. Flow Design & Structural Decisions

After clarifying the current situation, I: - Created target user flows - Evaluated alternative scenarios - Modeled the role, user, and card relationship

At this stage, the most critical issue was transforming complex corporate structure into a simple mental model.

3. Design Process (Wireframe → UI)

I managed the entire design process: - Structure was clarified with low-fi wireframes - Technical constraints were addressed early with teams - UIs were designed in accordance with iyzico's design system

Main Design Challenge: Enabling legal representatives to simultaneously understand and manage: - Users - Their roles - Cards

Especially when there are many sub-users and cards, keeping the system controllable was a critical requirement.

Solution Approach

Dashboard & Navigation

- Legal representative can switch between cards via dropdown on the main screen - Search activates when card count increases - Card → user → role relationship remains always visible

Card Application Flow

- Application starts with a list-format popup - User can search existing users within the popup - Can directly create a card for existing user

If user doesn't exist: - Drawer opens - New user creation → role assignment

If role doesn't exist: - Role creation - Assignment to user

While this nested structure is technically complex, it offers a natural step-by-step flow for the user.

Results & Impact

- ✓ Manual operation need in card applications significantly reduced - ✓ Corporate card usage rates reached target levels - ✓ Product became a strong gross profit item for iyzico - ✓ Legal representatives gained full control over the process

Post-Launch Problem & Improvement

After going live, an important user perception problem was identified:

Cards automatically sent to new users were being perceived as credit cards by some users and therefore weren't being activated.

Solution: - Physical card holder design was updated - In-panel explanations were simplified - Card's usage purpose was clearly explained

After these improvements, a significant increase in card activation rates was achieved.

Learnings & Personal Contribution

- I managed this project end-to-end from ideation to post-launch improvements - Throughout the process, I took an active bridge role between design, product, and technical teams - Proper problem definition and technical alignment at an early stage directly affected the project's speed and success

My biggest learning: In automated systems, success is possible not only through technical accuracy, but by properly managing user perception.

Impact Summary

✓ Self-service card management system launched ✓ Manual operational burden reduced ✓ Card activation rates significantly increased ✓ Strong revenue stream created for the company
