Overview
Overview
In today’s fast-paced food and beverage industry, every second counts.The small disruption can lead to significant revenue loss and employee stress.
I led the mobile design for Toast POS, a solution built to streamline order management, reduce reliance on error-prone manual processes, and deliver instant, actionable analytics.
Through rigorous user research, iterative prototyping, and extensive stakeholder testing, our redesigned point-of-sale system minimizes manual work, streamlines order management, and delivers instant, actionable insights for scalability. Our solution empowers frontline staff and business owners to operate with confidence and efficiency.

The Challenge
The Challenge
Local food service businesses face chronic technology failures and inefficient manual workarounds. Stakeholders reveal that unreliable POS systems, whether it’s a Square device that crashes or a system with limited automation, force staff to adopt time-consuming, error-prone manual processes like spreadsheet tracking and ad hoc communication. These challenges lead to operational inefficiencies, disrupted workflows during peak hours, and mounting anxiety over potential revenue loss.
The core challenge was clear: design a flexible, reliable, and scalable POS system that not only remedies these issues but also adapts as businesses grow.

Our research combined direct stakeholder interviews and supplementary quantitative data to capture the full spectrum of challenges:
Unreliable system, unpredictable failures
Camellia Rd highlighted that “Square just stops working pretty often,” leading to prolonged downtime. Mix + Matcha echoed this frustration, noting that their iPad-based POS often crashes during peak hours so they have to rely on slower, phone-based transactions.
Dependence on manual processes
Both Camellia Rd and Gleem Energy reported that frequent system failures force them to rely on error-prone manual solutions. Camellia Rd uses Google Sheets for inventory tracking, while Gleem Energy relies on manual text messages to coordinate orders.
Need for integrated digital system
Friends of Friends explained that managing daily tasks with physical tools (e.g. whiteboards and paper task lists) is a hassle. Mix + Matcha suggested an intuitive ticketing system that could facilitate order transfers between devices.
Adapting as business grows
Gleem Energy emphasized the need for a system that scales with growing demands. Mix + Matcha reinforced this by calling for automated, integrated features.

Design Process & Iterations
Design Process & Iterations
Low-Fidelity Prototyping
Based on our research, we mapped out two primary user flows:
Customer Ordering Flow: A streamlined journey where users can effortlessly browse a menu, customize their orders via a pop-up interface, and review a dynamic order summary.
Business Management Flow: An interface aimed at employees for managing orders, which initially relied on a “Sort by” button and extensive scrolling.
Early low-fidelity prototypes and heuristic evaluations revealed significant pain points, such as scrolling fatigue and information overload, which led us to use a tab-based categorization system.

User Testing
User testing with stakeholders provided actionable feedback that we applied to iterations:
Enhanced Navigation
Replacing the generic “Sort by” button with distinct tabs (“All,” “Active,” and “Closed”) dramatically reduced scrolling and made order status immediately clearVisual and Functional Clarity
A prominent “New Order” button was added for quick manual entry
The initial receipt-like tab edges were scrapped in favor of a cleaner, mobile-friendly design that aligns with Toast’s branding
Timestamps and consistent color schemes improved clarity and reduced cognitive load

Handheld POS Prototype
I simulated a waiter's experience using a handheld Toast POS device:
Order Management
The interface displays recent orders in a vertical scroll. Tapping an order number reveals a detailed bill overview.Payment Flow
After reviewing the bill, employees can proceed to payment where customers can input a custom tip and select from multiple payment options (Apple Pay, Visa, Mastercard).User Benefit
This design enables faster order handling, reducing time pressure and cognitive load during busy service periods.
