Why it matters

Small leaks. Big losses.

Most stores don’t fail all at once. They leak: a confusing menu here, a surprise shipping fee there. Each one costs you sales you never see in your analytics.

70.22%

of online shopping carts are abandoned before the order is placed.

Not another automated report

Tools tell you what’s broken. We tell you why it matters.

A typical automated audit

  • A long list of scores, with no sense of what to fix first
  • Checks what it can measure, misses what customers feel
  • Knows nothing about your customers or your goals
  • Jargon your developer has to translate

A Flume review

  • A senior designer walks your store the way your customers do
  • Every finding judged against a published standard, with screenshots
  • Prioritised by impact and effort, so quick wins come first
  • Opportunities and growth ideas, not just problems
  • A video walkthrough of the biggest wins, in plain English

Yes, we use AI. It handles the grunt work: crawling pages, speed tests, accessibility scans, broken links. That frees our designers to spend their time on the things tools can’t judge.

How it works

From brief to better, in four steps.

Step 01

Order & brief

Tell us about your store, your customers and what’s keeping you up at night. It takes about ten minutes.

Step 02

Designer review

A senior designer works through your key journeys against hundreds of standards, with screenshots and notes for every finding.

Step 03

Your report

An interactive report with your Flume score, quick wins first, and a walkthrough video of the biggest opportunities.

Step 04

Fix & re-check

Flip the report into a to-do list, export it to your developer’s tools, then book a re-check to verify the fixes.

The report

One report. Two ways to use it.

A clear summary for you, and a working to-do list for whoever’s doing the fixing. Try switching views.

Questions

Good questions, straight answers.

Is this just an AI audit?

No. Every review is done by a senior designer. We use automated tools for the measurable things, like speed, accessibility scans and broken links, so our designers can focus on what tools can’t judge: clarity, trust and whether your site makes people want to buy.

What kinds of websites do you review?

Online stores are our speciality. We also review business and marketing websites, and publications like blogs and news sites. Not sure where yours fits? Ask us.

What do you need from me?

A short brief: your site, your sitemap, your customers, your goals and anything that’s bugging you. If parts of your site sit behind a login, we’ll ask for a test account.

Who fixes the issues?

You or your developer. Every finding comes with clear recommendations, and the report switches into a to-do list your developer can work through or export to their own tools.

How long does a review take?

[X] business days from your brief, depending on the size of your site.

Limited spots
