How to choose a UX design agency: six things to check before you sign

Choosing a UX design agency is more than picking a portfolio with good-looking screens. The right agency finds where your product loses users, designs the fix and hands it over in a way your team can build. Before you sign, we suggest checking these six things.

1. Does the portfolio show process, or only screens?

Final screens look good at every agency. The difference is how they framed the problem and what their decisions were based on. In case studies, look for the starting problem, the research, the alternatives tried and the result.

2. Have they designed your kind of product?

An enterprise dashboard, a mobile app, an e-commerce store and a marketing site need different expertise. If your product has complex workflows, look for a team that has designed screens of similar density.

3. How do they research and test?

"We're user-centred" is easy to say. Ask when and how they talk to users, how they read your existing data and how they test designs before launch. What they suggest when the budget is tight is a good sign too.

4. Can developers build what they hand over?

If the design files don't work for your development team, the product won't ship the way it was designed. Ask about a component library, states (empty, error, loading), accessibility notes and the developer handover. A team that can build a design system also keeps the product consistent as it grows.

5. Who will you actually work with?

Will the senior people who pitch also work on the project? What is the weekly rhythm, how is feedback collected and where are decisions recorded? A small senior team often moves faster than a large, scattered one.

6. How are scope, timeline and budget set?

A good agency tries to clarify your goals and scope in the first meeting rather than quoting a ready price. If they suggest working in stages (for example a UX audit first, then a redesign), they are also lowering your risk.

A short checklist

• Case studies explain the problem, the process and the result.
• They have experience with your kind of product.
• They can describe their research and testing methods concretely.
• Their handover works for your developers.
• You know who will work on the project.
• They suggest agreeing scope together, in stages.
