How Carrefour reduced revenue loss and streamlined error resolution with Noibu
About Carrefour Belgium and the road to error-free ecommerce
Carrefour is one of the world's largest retail and grocery brands, with a global present and a strong emphasis on digital transformation across its local markets. Carrefour Belgium operates a robust ecommerce arm powered by Salesforce Commerce Cloud (SFCC)—serving a growing base of online shoppers who expect speed, reliability, and seamless experiences at every step.
To ensure its digital storefront keeps up with modern ecommerce standards and customer expectations, Carrefour Belgium partnered with Noibu in 2021 to proactively detect and resolve revenue-impacting errors on its website.
Over a year into the partnership to date, we sat down with Jean Philippe Blerot (Head of Digital & Ecommerce Projects), Olivier de Koster (Ecommerce Product Owner), and Jessica Varisano (Digital Product Owner) to learn how Noibu has become a mission-critical part of their ecommerce operations—and how the tool continues to support their long-term success.
The challenge: Growing technical debt, hidden errors, and limited visibility
Carrefour's ecommerce team faced three core challenges:
- Identifying hidden or emerging errors
- Prioritizing issues based on business impact
- Tracing bugs to their root cause for faster fixes
While the team could often see symptoms of a problem, they lacked the technical visibility to go deeper.
“We were aware of issues before Noibu, we could see them, but there wasn’t enough information to relate back to the issue at a code line level."
— Olivier De Koster, Ecommerce Product Owner
“The biggest pain point was that we couldn’t find exactly where on the code the issue was, and it was very difficult to dive into the code in order to see what provoked the issue.”
— Jessica Varisano, Digital Product Owner
Event when a bug could be replicated, fixing it remained a time-consuming process:
"We could replicate [an error], but in order to do that, many of our developers needed to try and replicate the error to confirm its validity. And even if we found and validated a bug, we didn't actually know what needed to be done in order to solve it."
— Jean Philippe Blerot, Head of Digital & Ecommerce
With no ability to link issues to lost revenue, the team was left guessing which problems to tackle first.
Why Carrefour turned to Noibu
Carrefour needed a scalable, data-driven solution that could give them full visibility into website errors—across browsers, devices, operating systems, and third-party plugins—and help them focus development time where it mattered most.
With Noibu, they gained the ability to:
- Automatically detect all customer-impacting errors
- Quantify the revenue impact of every issue
- Surface root causes and error details for faster resolution
- Create an efficient, proactive workflow for site reliability
"If [our team] did not have a tool like Noibu, I presume it would take a minimum of one week to understand a bug, and two weeks to try and solve it."
— Jean Philippe Blerot, Head of Digital & Ecommerce
Short-term wins: Clearing the backlog and prioritizing what matters
When Noibu was first deployed, the team focused on triaging and eliminating a large technical backlog. Noibu surfaced previously undetected bugs—many tied to revenue-impacting parts of the site like product pages and checkout.
Armed with clear business context, the Carrefour team could now:
- Focus on the errors causing the most revenue loss
- Resolve long-standing bugs that had gone unsolved
- Speed up developer workflows using Noibu's developer tba
Thanks to these fixes, Noibu helped Carrefour recover over $383k in potential annualized revenue, and achieve a 49.5x annualized ROI within the first year.
Long-term value: Scalable ecommerce error and performance monitoring
Noibu is now embedded into Carrefour Belgium's long-term ecommerce operations. It's not just a one-off cleanup tool—it's a foundational part of their website health strategy.
Key advantages include:
- Ongoing visiblity into all site errors
- Accurate revenue attribution to guide prioritization
- Faster root cause identification to reduce dev time
- Continuous monitoring across third-party scripts, device types, browsers, and extensions
As new bugs are introduced over time—through updates, integrations, or user behavior—Noibu ensures nothing goes undetected.
Today, just 10-20% of spring time is dedicated to error resolution, a major reduction from the past.
"It's all about [maintaining] the quality of the code and to help the development team work quickly. Time is money so it's important for us to help the team work as efficiently as possible."
— Jean Philippe Blerot, Head of Digital & Ecommerce
What makes Noibu different
Many ecommerce monitoring tools offer alerts or session replays—but Noibu goes deeper by combining technical diagnostics with business impact visibility. This has helped Carrefour transform how they approach website maintenance:
- No more guessing what to fix first
- No more reactive, ticket-based triage
- No more time-consuming reproduction attempts
"The biggest win with having Noibu onboard long term is the ongoing prioritization and the help for our development team to find their way in our [error tickets]."
— Jean Philippe Blerot, Head of Digital & Ecommerce
With Noibu, the team can focus less on firefighting and more mon delivering high-quality digital experiences—and launching new initiatives with confidence.
