Walmart Seller app: Designing a 0 to 1 mobile experience

I'm currently working on the Walmart Seller app, a new mobile experience for third-party sellers. I helped shape the information architecture, define and ship core features, lead the migration to new design tokens, and build a mobile pattern library. In close partnership with product, engineering, accessibility, and content, we're crafting a scalable, intuitive experience.

Goal

Empower Walmart sellers to manage their business anytime, anywhere with a fast, flexible mobile experience for handling orders, messages, and listings. The result: less friction, more time saved.

Surfacing the right problems

We began by identifying the highest-impact seller tasks through stakeholder interviews, support tickets, and usage data from Seller Center, the existing desktop platform. We also leveraged insights from Pendo and Doorbell.io to surface pain points and opportunities. From there, we mapped key workflows and designed a mobile-first IA focused on speed and clarity.

Seller Summit

In August 2024, we announced the Walmart Seller app at the Let’s Grow! 2024 Seller Summit in San Francisco, introducing the experience to thousands of sellers. The reveal marked a major milestone and generated early excitement, setting the stage for deeper engagement and ongoing iteration.

Testing, feedback, and iteration

Following the announcement, we worked closely with our UX research team to run usability tests, user interviews, and gather insights from a beta testing group of over 1,500 sellers. Their feedback helped us validate assumptions, refine features, and make informed design decisions. We also A/B tested key interactions to optimize the experience.

Scaling through systems

As we progressed through development, Walmart’s recent rebrand enabled us to adopt new design tokens and establish a mobile pattern library that can be reused across teams.

Impact

Simplified navigation · 40% faster task completion

A redesigned information architecture made it faster and easier for sellers to find what they need, reducing cognitive load and improving task flow. Usability testing showed a 40% improvement in task completion speed over the previous desktop experience.

Faster listing flow · 17% drop in abandonment

The new “Scan to Add” feature eliminated manual barcode entry, streamlining how sellers search and list products. A/B testing showed a 17% drop in flow abandonment compared to the legacy input method.

Mobile-first foundation · 92% felt more in control

Designed a mobile experience tailored for sellers on the go, solving a key limitation of the desktop-only Seller Center. Early survey data showed that 92% of beta testers felt more in control of their business using the mobile app.

Reusable and inclusive system · 25% reduction in design VQA time

Built a mobile component library aligned with Living Design 3.5, implementing updated design tokens and accessibility specs. This reduced design VQA time by about 25 percent and laid the foundation for broader team adoption.

Validated with real users · 88% weekly active · 61% daily active

Feedback from more than 1,500 beta testers guided iteration. Eighty-eight percent returned weekly, and 61 percent engaged daily, fueling data-backed refinements across key flows.
