Rebuilding the tariff tiles

Consumer self-care portal for a national telco. We rebuilt the plan/tariff tiles used for upgrades and plan changes—replacing repetitive cards with a clear, comparable grid.

Old tiles were repetitive and hard to compare (price/benefits formatted differently across cards).

  • No clear current vs. candidate distinction; users feared hidden changes (data cap, throttling, roaming).

  • Inconsistent components (design-system drift); poor mobile scan; accessibility gaps.

  • High “Which plan should I pick?” contact volume; plan-change completion lagged.

10-Day Clarity Review: identified confusion drivers; set KPIs (plan-change completion, support contact rate, ARPU on change).

  • Comparison-first tile model: standardized rows (flats, speed/throttle, roaming/EU)

  • Decision helpers: easy comparable groups, no mental overload, structured and clean design

  • System-aligned components: tokens, states, focus styles; WCAG 2.1 AA color/contrast; responsive grid for mobile scanning

  • Validation & instrumentation: hi-fi prototype, 8 user tests, event tracking


Easier Comparison, More Trust


With their new tariff site, the telco company achieved a much better user experience.

Project images are handled through multi-reference.

This flexible image system allows you to showcase your work in its best light on project pages. Multi-reference lets you upload images to your CMS and select the ideal ratio for each specific context, add custom descriptions, and create side-by-side image comparisons - all while maintaining visual consistency throughout your portfolio.

Which allows your project pages to be highly adaptable.

Unlike traditional templates with rigid image slots, this system gives you complete freedom to present unlimited project images without modifying the template structure. Your portfolio adapts to your content rather than forcing your work to fit predetermined formats, ensuring your projects look professional across all devices.

Add optional descriptions to explain your work.

Enhance your project showcases with tailored descriptions that provide context and highlight key aspects of your process. These optional text blocks let you emphasize specific features, explain challenges you overcame, or detail the results achieved for the client.

You can select ratios for your images.

Choose from various aspect ratios to present your work in the most flattering format. This flexible system allows you to optimize each image display based on content type - whether you need widescreen presentations for landscapes or square formats for logos.

For example this image is using a 16:9 ratio.

Widescreen formats are perfect for showcasing device mockups, web designs, and panoramic visuals. The 16:9 ratio provides a cinematic feel that works exceptionally well for digital interfaces and presentation-style content.

And this one is using a 4:3 ratio.

The classic 4:3 ratio offers a balanced frame for product photography, print work, and traditional layouts. This proportion provides more vertical space, making it ideal for packaging designs, book covers, and print materials.

You can even add a second image.

Create powerful visual comparisons by placing images side by side. This feature is perfect for before/after demonstrations, showing variations of a design, or presenting multiple views of physical products. Paired images tell a more complete story of your creative process.
