Project Overview
StoreOS was envisioned as a mobile-first, cloud-native Point-of-Sale solution that could empower store staff, streamline daily operations, and elevate the customer experience — all in one unified platform. Our goal was to design a flexible tool that could support businesses of every scale, from boutique fashion stores to large multi-brand retail chains.
This wasn’t just about digitizing checkouts. It was about reimagining the entire in-store experience: allowing staff to move freely across the floor, manage inventory in real-time, serve customers faster, and sync seamlessly with backend systems like CRM, inventory, and ecommerce platforms.
With StoreOS, we weren’t just building software but we were building a new standard for how physical stores operate in a digital-first world.
The Challenge
Traditional POS systems couldn’t keep up with modern omnichannel retail demands
Retailers wanted to offer seamless features like endless aisles, self-checkout, in-app promotions, and integrated order management. But traditional POS systems lacked real-time inventory sync, remote selling capabilities, and personalized staff support.
User Problem
Sales associates often found themselves stuck behind the counter, with limited access to product, customer, or inventory data. Managing returns, creating custom carts, or handling order pickups from online channels was a time-consuming process riddled with manual dependencies.
Business Goals
From a business perspective, the lack of real-time sync with ecommerce, warehouse, and CRM platforms made it difficult to get a unified view of performance or respond swiftly to store-level issues. There was a growing need for a POS system that could behave like a "store operating system" — something more dynamic, flexible, and intelligent.
Impact

These numbers underscore how Store OS didn’t just replace outdated POS terminals—it became a catalyst for growth and efficiency. By enabling in‑store mobility, real‑time insights, and unified operations, the platform has helped retailers both improve customer experiences and drive tangible business results.

The Research
We conducted informal interviews and observational studies across a handful of pilot locations to understand how store staff interact with traditional POS terminals — what slowed them down, where they needed flexibility, and which actions they repeated the most.
We also listened to pain points from sales managers who juggled between multiple tools for inventory, checkout, returns, and reporting. This input directly informed how we prioritized our product roadmap and validated the core features of the mobile-first POS experience.
Key Findings:
We mapped current flows used by store operators, floor sales staff, and sales managers, and identified several recurring pain points:
Our early research — built on informal interviews and real-time observation of store staff and managers — revealed how outdated POS systems created operational friction at every level. Instead of working seamlessly, tasks were split across disconnected devices, multiple software tools, and manual workarounds.
Sales staff had to move back and forth between customers and fixed counters for every transaction, breaking the flow of engagement and slowing down checkout.
Store operators struggled with inventory visibility. Updates were delayed, which led to miscommunications, overpromising to customers, or lost sales.
Sales managers juggled between multiple systems to access sales data, issue returns, and track team performance — all of which meant slower decision-making and poor customer experience.
The Process
Understanding Roles in the Retail Environment:
Before jumping into design, we needed to deeply understand how different people interacted with in-store systems on a day-to-day basis. We spent time observing store operators, sales associates, floor managers, and cashiers to capture their responsibilities, workflows, and pain points.
What we discovered was a layered environment where each role had unique tasks but shared overlapping needs — such as quick access to inventory, seamless transaction processing, and real-time visibility into store performance. Sales associates needed mobility and speed to assist customers on the floor. Managers sought tools to track team performance and sales metrics. Store operators prioritized inventory accuracy and operational control. Recognizing these differences allowed us to shape a flexible solution that could adapt to specific responsibilities without complicating the overall system.
Mapping User Flows and Edge Cases
With roles defined, we mapped their typical day-to-day interactions with the old POS systems — from checking inventory to completing a transaction, issuing returns, and managing staff shifts. These flows exposed inefficiencies that weren’t obvious on paper but were deeply felt in-store.
We documented not just the ideal workflows, but also edge cases — like what happens when an item isn’t in stock, or a customer wants to pay across multiple modes. These edge cases highlighted friction that disrupted the experience for both staff and customers. Some salespeople would leave the customer mid-journey to fetch information or access another system. Others manually coordinated with stock rooms due to outdated data.
The Solution
To bridge the gap between traditional in-store operations and modern retail expectations, we designed Fynd Store OS as a comprehensive point-of-sale ecosystem. Built from scratch, it introduces both mobile and terminal POS systems, enabling seamless, real-time retail management across roles and store formats.
Some of the most impactful solutions included:
Seamless Checkouts Across Devices
With both mobile and terminal POS systems, store associates can assist customers from anywhere, while self-checkout stations reduce wait times. This flexibility transforms the entire checkout journey into a faster, more convenient experience.
Unified Retail Operations
Fynd Store OS acts as a single source of truth for product catalogs, inventory updates, and order management. Automated store reassignments and seamless integrations make operations smoother across all retail functions.
Elevated In-Store Experiences
By equipping staff with digital catalogs, saved carts, and personalized recommendation tools, the system enhances every customer interaction—making shopping more personal, efficient, and enjoyable.
Smarter Store Management
From real-time analytics to staff performance tracking, in-app returns, and promotions—store operations are optimized for clarity, control, and accountability, all within one system.
Scalable for Growth
The platform enables cross-selling, upselling, and distance selling, all while providing quick support through the app—giving businesses the tools to grow revenue and retain customers at scale.
Final Design
Terminal POS Experience
The terminal POS system was crafted for speed, stability, and consistency at the checkout counter. Designed for high-traffic in-store environments, it supports quick transactions, barcode scanning, split payments, and centralized inventory visibility. Its layout prioritizes efficiency, making it easier for store staff to serve customers without friction.
Mobile Experience
The mobile POS is built for flexibility on the floor. Sales associates can access product catalogs, initiate transactions, manage customer carts, and even place orders from anywhere in the store. This helps personalize the experience and reduce long queues by turning every associate into a checkout point.
Key Learnings:
This project pushed me to think beyond screens and truly understand the ecosystems users operate within. Here’s what stood out:
Designing for edge cases is non-negotiable
Retail environments are unpredictable — handling offline sync, unstable networks, and shared devices was critical.
Hardware constraints shaped our UX
Touch-first interfaces, barcode scanners, and varying screen sizes pushed us to rethink interaction patterns.
Operational tools need intuitive defaults
Busy staff don’t have time to explore — smart defaults and quick actions improved usability dramatically.
Real-world testing revealed what mockups missed
On-site observations in stores helped us refine flows, validate assumptions, and remove unnecessary steps.
