The challenge: Hidden checkout friction that engineering couldn't reproduce

Jennifer Rodriguez has been with Guess for over eight years. She started in customer service, where she heard directly from shoppers struggling to complete purchases. She knew there were problems — she just couldn't prove them to engineering.

"I knew that there was a lot of room for improvement, just because I knew on the frontend what the customers were dealing with, but I also knew that for the backend engineers, a lot of the issues were nearly impossible to recreate to try and figure out the root cause."— Jennifer Rodriguez, Ecommerce Operations Analyst, Guess

This is a common challenge in enterprise ecommerce: customer-facing teams see the symptoms (abandoned carts, support tickets, complaints), but engineering teams can't replicate the bugs in a test environment. Without session-level evidence and revenue attribution, issues either go unresolved or get deprioritized behind feature work.

Guess needed a way to:

• Surface errors proactively — not wait for customer complaints to flag them
• Quantify the revenue impact of each issue so engineering could prioritize effectively
• Give engineers reproducible evidence — full session data, stack traces, and environment details — so they could fix issues fast

The solution: Full visibility into what was actually happening at checkout

When Rodriguez transitioned into her ecommerce operations role, she made it her mission to improve the digital shopping experience. But she needed more than traditional QA or analytics — she needed a platform that could show her what was actually happening across every session, surface the issues she couldn't see in dashboards, and tie each one to real revenue at risk.

That's what led her to Noibu.

Noibu gave Rodriguez and the Guess engineering team:

• Automated error detection across the full shopping journey — from product pages through checkout and payment
• Revenue-impact scoring for every issue, so the team could focus on fixes that would move conversion and protect revenue
• Session-level evidence — including full reproduction steps, technical stack traces, and user environment details — that eliminated the back-and-forth between ecommerce and engineering
• Proactive alerts on new and recurring issues, so problems could be caught before they scaled

Instead of relying on customer complaints or periodic QA sweeps, Guess now had a continuous, always-on view of checkout health — with every issue connected to the revenue it was putting at risk.

The results: 82% → 88% checkout conversion and a 9.31x ROI

The impact was measurable and fast.

Checkout conversion rate: +6 percentage points

Before Noibu, Guess's checkout conversion rate sat at 82%. After identifying and resolving the hidden errors and friction points that were silently blocking purchases, that number climbed to 88% — a 6-percentage-point improvement that translates directly to recovered revenue.

ROI: 9.31x

Rodriguez quantified the return clearly:

"Noibu has worked with me and our engineers to really smooth out the process, and to date, our ROI has been 9.31x."— Jennifer Rodriguez, Ecommerce Operations Analyst, Guess

Prioritization based on revenue impact

Beyond the headline metrics, the shift in how Guess prioritizes fixes has been transformational. Every issue in Noibu is scored by its estimated impact on revenue — which means Rodriguez can walk into a sprint planning meeting with data, not anecdotes. Engineering fixes the issues that matter most to the bottom line first.

Faster resolution, less back-and-forth

Because Noibu captures full session reproductions with technical detail, engineers no longer spend cycles trying to replicate bugs that only appear in specific browsers, devices, or user flows. Issues move from detection to resolution faster — freeing up engineering time for innovation rather than firefighting.

Why it matters: What other ecommerce teams can learn from Guess

The Guess story illustrates a pattern Noibu sees across hundreds of ecommerce brands:

1. Checkout friction is often invisible. The issues that cost the most revenue aren't the ones customers call about — they're the ones where shoppers silently abandon.
2. Customer service teams see it first. The people closest to the customer often know something is wrong long before the data shows up in analytics dashboards.
3. Revenue attribution changes prioritization. When every bug has a dollar sign attached, the conversation between ecommerce and engineering shifts from opinion-based to evidence-based.
4. Small conversion gains at checkout are worth a lot. A 6-percentage-point lift at the checkout stage — where traffic is already highly qualified — has an outsized impact on total revenue.
