Case study: redesign raised the average check by 27%

Most companies intuitively feel that the old interface is eating away at sales. But when we relaunch the website design systematically, the metrics change in a measurable way. In our case study, after a deep UX/UI approach and an identity update, the average check increased by 27%. Below is how we achieved this, what stages worked, and what it means for your revenue.

🎯 What really affects the average check after a redesign

The effect begins not with a “more beautiful” main page, but with a clear user scenario. We work with motivations, barriers, and critical points along the way. The redesigned UX removes friction in the shopping cart, suggests relevant upsells, and builds trust. This is how the logic is formed, where the customer chooses more expensive configurations and is more willing to add related services.

Global analytics confirm the trend. According to McKinsey (2018), the literal formula is as follows:

“Companies that are design-driven achieve revenue growth of around 20-30% from improved user engagement.”

When convenience improves, conversions also improve. Research by Nielsen Norman Group (2022 ) emphasizes:

“Improvements to site usability have resulted in conversion rate increases of up to 83%. “

In our practice, this is reflected in a direct result: “After the implementation of our client’s new website design, the average check increased by 27%.” This is not about chance. This is about the controlled effect of the right interface architecture and a well-thought-out visual system.

🧭 Method: from audit to implementation without “cosmetics”

Audit and hypotheses

We start with an audit of the existing interface. We record gaps in navigation, information architecture, and micro-interactions. This is where we come up with hypotheses about how UX/UI design can affect the average check: simplified configurators, more visible upsells, transparent guarantees, and more noticeable advantages of more expensive packages.

Prototype and concept approval

Next, we create an interactive prototype. It allows you to go through user scenarios without being distracted by graphics. At this stage, customers often see for the first time how the funnel flows differently. Here we agree on the logic, content blocks, future cross- and upsell points for landing page design and multi-page solutions.

Visual identity and responsive design

At the same time, we create a unique visual system. We update typography, color accents, patterns, and illustrations. It is crucial that the development of the website design takes into account the mobile scenario, because it is there that the issue of trust and purchases for a larger amount is often decided.

🧩 What exactly did we change: application solutions

Transparent product selection logic

We have repackaged the page structure so that the options for packages and tariffs can be read without stress. We added clear comparisons, explained the difference “why is it more expensive” with simple arguments. As a result, users are less likely to “save money” where quality is important.

Micro-interactions leading to upsell

Contextual tips, microcopies, highlighted button states. Such little things control attention and help to form more expensive baskets unnoticed. Embedded blocks with relevant add-ons work better than intrusive popups.

Faster scripts, less friction

Reduced the number of steps in critical processes. We made the checkout process clearer, strengthened the trust and social proof blocks. When the UX and visual design of the website remove doubts, the average check grows organically. This is also in line with the practical conclusions about the role of usability in conversions reported by Nielsen Norman Group (2022).

🚀 How to scale the result for your business

Creating a roadmap

After the release, it’s important not to stop. We set measurable goals and prepare an iteration plan. For corporate web resources, we offer corporate website design with a focus on ROI, sales, and support for a complex content structure.

Integration with development

The team synchronizes design and front-end to prevent the interface from breaking in the code. The full cycle allows you to speed up the launch and avoid loss of quality. If you need end-to-end support, we take over the development of the website with technical support.

Comprehensive effect

Redesign lays the foundation for organic and paid growth. High-quality UX/UI design boosts SEO, improves the quality of PPC traffic, and reduces CPA. As part of a full-cycle approach, you can connect website design as a basic service and scale the result through related channels.

The conclusion is simple. When the interface works according to the rules of user psychology, the business gets a predictable increase. Our practical result – 27% increase in the average check – fits the logic of McKinsey and NNG’s global observations and confirms the power of a systematic approach rather than a “cosmetic” update.

What specific redesign steps led to a 27% increase in the average check?

We conducted an audit, created a prototype, agreed on the concept, updated the visual identity, and adaptive. We focused on transparent selection logic, micro-interactions for upselling, and simplified checkout.

Why do you focus on usability and not only on the visual part?

According to Nielsen Norman Group (2022), “Improvements to site usability have resulted in conversion rate increases of up to 83%.” Ease of use directly affects conversion and average check.

Is the impact of design on revenue confirmed by independent research?

Yes, it is. According to McKinsey (2018): “Companies that are design-driven achieve revenue growth of around 20-30% from improved user engagement.” This correlates with our result of 27%.

How do you ensure consistency between design and development at the implementation stage?

We work in a full cycle: design, frontend, and testing in one team. This minimizes quality losses and speeds up the release.
