--- title: "Sunday: B2B App Process and UX Case Study | Murarum" description: "How we mapped the flows and processes behind Sunday's B2B merchandise application, then designed its UX and UI for desktop, tablet and mobile." url: https://murarum.ro/en/work/sunday-merch-platform language: en alternate_ro: https://murarum.ro/proiecte/platforma-merch-sunday --- Sunday · Branded merchandise platform · 2026 # Sunday's B2B app, designed around how the work flows. For Sunday, a platform where companies design, produce, store and ship branded merchandise to 200+ countries, we analyzed the flows and processes behind its B2B application and designed the UX and UI on top of them. The application is where business customers run their merchandise programs. Our scope was analysis and design, not implementation.

Sunday's business customers do more than place orders. They keep merchandise in stock, send it to people, run gifting and recognition programs and follow what happens after delivery. The B2B application is where that work comes together. Several groups of people use it: the teams that run merchandise inside a company, the people who receive it, partners who manage it for several companies, and the Sunday team that supports every account. Challenge ## Many paths, one coherent product. When an application has to carry this many tasks, the risk is a screen for every request and no clear path between them. Each flow has to make sense on its own and still feel like part of the same product. It also has to work for people who use it every day and for people who see it once, on desktop, tablet and phone. What we did ## Process first. Then UX. Then UI. We started with the flows and processes: who does what, in which order, and where a task passes from one person to another. Mapping them before drawing screens meant every screen had a reason to exist. From there we designed the user experience, the structure and navigation of the application, and then the interface: a calm, consistent visual language, a shared set of components and layouts for desktop, tablet and mobile. The work lives in Figma, organized by product area, with prototypes of the key flows. Outcome ## A complete design, grounded in process. Sunday received the process analysis and a complete UX and UI design for the application, covering every product area from sign-up to reporting. Implementation was not part of our scope, and usage figures are Sunday's to share. We describe the work at a high level on purpose: the details of how Sunday operates belong to Sunday. The design ## The design, up close. Selected frames from the Figma design, with sample data: the dashboard, one flow seen from a distance, and the same dashboard on tablet and phone. ## Questions about this project ### Where did our part start, and where did it stop? We analyzed the flows and processes the application has to support, then designed its user experience and user interface for desktop, tablet and mobile. Implementation was not part of our scope. ### Why start with processes instead of screens? Because screens follow work. When the flows are clear first, each screen has one job and the path between screens follows the way people actually work. Designing screens first tends to reproduce whatever confusion already exists. ### Why does this case study stay at a high level? The application is a working tool for Sunday and its customers, and the details of their processes belong to Sunday. We describe the approach and the kind of result, not the inner workings. Usage and results are Sunday's to publish. [Still have questions?
