Overview
The Outdated Rewards System And Lack Of Promotional Tools Were Limiting Business Growth And Customer Engagement.
Nombolo's rewards system was a core feature for driving customer loyalty, but it created friction for both businesses and customers. Businesses found the reward setup confusing and inconsistent, coupons, a highly requested promotional tool didn't exist, and customers struggled to discover and redeem available rewards. This directly impacted business retention and platform engagement.
Problem
The Rewards System Was Built For One Business Model, Not For Platform Growth Across Different Business Types.
Confusing Setup
Missing Features
Limited to Stamp Cards
Businesses found rewards setup confusing and unclear. Copy was confusing, guidance was minimal.
Coupons are a critical promotional tool requested by many businesses. This limited marketing capabilities and campaign flexibility.
Stamp cards were only needed by repeat purchase businesses like cafe's . But other businesses like retail, clients wanted a coupon based system.


OUTCOME
flexible promotions for different business models
Businesses were positive about the flexibility of promotions.
Similar patters in the setup process of stamp cards and coupons reduced cognitive load and reduced setup time.
Dashboard integration improved day-to-day management for businesses.
Established a foundation for scalable promotional tools.
Research
Understanding Business Needs Without Historical Data
With no analytics on stamp card usage and coupon, I analyzed competitive reward platforms like stamped.me, Magic stamp, Stamped.IO for stampcard. gathered business feedback to inform the redesign strategy.
Platforms analyzed for coupons
Shopify - E-commerce discount structures
Toast - Restaurant promotional tools
Square - Small business POS coupons
Wix - Online store discount patterns

SHARED DESIGN PATTERNS
Architectural Decision For Automatic Conversion
Architectural Decision For Automatic Conversion
While stamp cards and coupons serve different purposes (Rewards vs. Coupons), I intentionally designed their core reward structure identically to enable seamless automatic conversion.

Shared Configuration for stampcards and coupons

Why This Matters
This shared architecture enables automatic conversion. When customers complete a stamp card, the final reward seamlessly becomes a redeemable coupon in their wallet, no manual steps, no friction, no drop-off. The engagement loop continues unbroken.

Separate Flows With Cohesive Design Patterns
Separate Flows With Cohesive Design Patterns
I designed distinct creation flows for stamp cards and coupons to accommodate their different mechanics while maintaining visual and interaction consistency across both.

Stampcards/ Rewards
Stampcards/ Rewards
Since Stamp cards are loyalty programs, businesses set how much customers need to spend per stamp, and customers collect stamps over time to earn a final reward. The expiry is measured in months because it's a long-term program.

Coupons
Coupons
I designed the coupon system to feel intuitive for business owners while supporting diverse promotional strategies. The flow uses familiar patterns, visual previews, and optional fields to balance flexibility with simplicity. Businesses set a discount that applies right away, and they usually run for specific date ranges like 'this weekend only' or 'holiday sale.'

Contextual guidance with tool tips
I incorporated strategically placed tooltips and helper text that appear at the moment of need, keeping users focused without disrupting their flow.

Centralized Management For Rewards And Coupons
Centralized Management For Rewards And Coupons
I created a unified dashboard providing quick access to rewards, coupons, posts, and customer engagement tools, reducing context switching and enabling faster action. Introduced action-focused language for busy business owners. Streamlined confirmation steps to reduce errors

Balancing Complexity & Usability
Balancing Complexity & Usability
In a fast-paced startup, I learned that speed doesn’t have to mean sloppy design. A key challenge was keeping rewards and coupon flows consistent while meeting complex business and technical needs.
The rewards setup flow balances this well, it mirrors how businesses think about loyalty programs while staying simple and scalable. Close collaboration with engineers and defining assumptions early helped us move fast without compromising quality.
I tackled this by:
Creating reusable components for consistency
Working closely with engineering to balance feasibility and UX
Maintaining familiar patterns while adding new functionality
