Most product teams know something is wrong before they know what it is. Conversion stalls, support tickets pile up around the same screens, or a redesign ships and the numbers barely move. UX audit services exist for that moment: an outside team evaluates the product against usability principles, real behavior data and, increasingly, accessibility standards, then hands back a ranked list of what to fix first.
The firms below were chosen because each one sells the audit itself as a defined service, with a stated scope, method and deliverable, rather than burying it inside a broader design retainer. Some run ecommerce UX audits built on years of checkout research, some package a heuristic evaluation into a fixed fee, and some pair the review with conversion testing so the findings turn straight into experiments. If you need open-ended discovery work instead, our guide to UX research and usability testing agencies covers that side of the market.
Use the table for a quick shortlist, then read the profiles to see which method fits your product and budget.

1. Baymard Institute — Ecommerce UX Audits Scored Against 700+ Research-Based Guidelines
Baymard Institute is the reference point for ecommerce UX audits. Founded by Christian Holst and Jamie Holst and based in Farum, Denmark, the company has built its reputation on large-scale usability research: its site cites more than 200,000 hours of testing across 35+ ecommerce industries, and that research library is what its auditors score your store against.
The full-site audit covers roughly 500 UX parameters across desktop and mobile, spanning homepage navigation, on-site search, product lists, product pages, cart and checkout, and account flows. The deliverable is concrete: a report with 40 research-backed recommendations ranked by conversion impact, implementation examples from other retailers, a UX performance scorecard, and a competitive comparison against stores you select. Baymard then walks your stakeholders through the findings in a roughly two-hour presentation and supports implementation with up to four advisory calls. A full-site audit typically takes 15 to 25 business days.
Baymard also sells focused audits for single areas such as ecommerce search, product lists, homepage and category navigation, and mobile commerce, which suits teams that already know where the problem sits. Testimonials on its site come from teams at brands including Sony PlayStation, Harley-Davidson, Staples and CVS Health.
Best for: Mid-market and enterprise retailers that want an ecommerce UX audit grounded in published research and benchmarked against competitors.
2. Box UK — Fixed-Fee £5,000 UX And Conversion Audit With Annotated Issue Log
Box UK is a London digital consultancy founded in 1998 that has packaged its audit work into a clearly priced product. Its UX and Conversion Audit is sold at a fixed fee of £5,000 and is designed to return results in days rather than weeks, which makes it one of the easiest UX audit services in the UK to budget for.
The fixed-fee audit has four defined deliverables. A heuristic UX review evaluates the interface against established usability principles. An annotated issue log documents every problem with screenshots and severity ratings. An analytics review and conversion funnel analysis shows where users drop off. Finally, a priority action plan ranks improvements by impact and implementation effort, so developers know what to pick up first.
For larger products, Box UK runs a broader UX audit that adds stakeholder workshops, user journey analysis, WCAG accessibility and performance reviews, and competitor benchmarking. The company holds ISO 27001 and ISO 9001 certification and is a Crown Commercial Service supplier, which matters for public sector and regulated buyers. Case studies on its audit pages include Rentalcars.com, the Royal Photographic Society and the Royal Yachting Association.
Best for: UK organizations that want a website UX audit with a fixed price, a defined scope and an issue log developers can work from directly.
3. Speero — Three-Week Heuristic Review Built On A 60-Guideline Persuasion Framework
Speero started in 2011 as the agency arm of CXL, co-founded by Peep Laja, and rebranded to Speero in 2020. It now operates from Austin, London and Tallinn, and its audit work is built for teams that plan to experiment on what the audit finds rather than simply redesign.
Its Quick UX Audit, also called a UX Heuristic Review, runs about three weeks. Speero evaluates the main user journeys against its own framework of 60 guidelines grouped into five themes: value, relevance, clarity, friction and motivation. That framing means the review looks for persuasion gaps as well as usability errors.
The process includes an intake survey and analytics review, a collaborative heuristic workshop that can include up to 30 people from the client side, a deeper analysis by Speero strategists and a findings presentation. Recommendations land in an Airtable database sorted into “just do it” fixes, A/B test ideas and items that need further investigation. Clients named in Speero’s case studies include MongoDB, Codecademy, Miro, ClickUp and Dr. Squatch.
Best for: SaaS and DTC growth teams that want a UX review whose output feeds straight into an experimentation backlog.
4. The Good — Productized Ecommerce Critiques From $199 With Video Reviews And Mockups
The Good is a Portland, Oregon optimization firm founded by Jon MacDonald in 2009. Its main offer is the Digital Experience Optimization Program for ecommerce and SaaS brands, but it also runs Commerce Critiques, a productized audit line that brings expert UX and conversion review within reach of smaller stores.
Commerce Critiques is sold in three fixed packages: a one-page video review, a three-page video review, and a three-page review with a written report that adds competitor analysis and multi-device testing. Published prices start at $199 for a single page and run to $2,499 for the comprehensive package. Every package includes eye-tracking heatmaps, a recorded expert review from a CRO strategist, design mockups of the suggested changes and a prioritized action plan. Turnaround ranges from two to three business days for a single page to seven to ten days for the full report.
Brands that outgrow the critique format can move into The Good’s full program, which adds research, analytics, testing and design. The firm is a certified B Corporation, and clients shown on its site include Adobe, Nike, Xerox, The Economist and Autodesk.
Best for: Online stores that want a fast, affordable ecommerce UX audit of their highest-traffic pages before committing to a larger program.
5. Make it Clear — Published £6,000 To £12,000 UX Audits With Proto-Personas And Maturity Scoring
Make it Clear is a UX and product design agency based in Twickenham, London, with a Manchester presence and more than two decades of experience. Its UX audit page is unusually transparent: it publishes a price range of £6,000 to £12,000 depending on scope, and lists exactly what the engagement contains.
The audit has six components. An analytics review finds high drop-off pages, rage clicks and funnel leakage. A heuristic evaluation scores the product against usability principles including Nielsen’s ten heuristics. A UX review walks through the product page by page or flow by flow. A competitor review benchmarks against direct rivals. Proto-personas, assumption-based user profiles, give the findings a user lens without the cost of full research. The final report pairs recommendations with an indication of the organization’s UX maturity.
The maturity element sets Make it Clear apart for organizations that suspect the problem is partly process, not just interface. Engagements range from several weeks to several months. The agency’s portfolio includes work for Spamhaus, Cambridge University Press & Assessment, Imperial College London and The Design Museum.
Best for: B2B, SaaS and education products that want a scoped UX audit agency with published pricing and a view on team maturity.
6. Cyber-Duck — Accessibility-Led UX Audits Backed By Its Own Heurix Evaluation Tool
Cyber-Duck has been a user-centred design and technology agency since 2005 and now operates as part of CACI Digital Experience from London. Its UX audit is positioned as a fast, cost-effective way to find quick fixes and judge the general UX of a site, and it can be run at any stage of the product lifecycle.
The core method is heuristic evaluation, extended in broader “UX MOT” engagements with qualitative and quantitative research and usability testing. Accessibility is built in rather than bolted on: the audit explicitly assesses the accessibility of the site, and the team holds IAAP membership. The deliverable is a plain-English report with practical recommendations, split between immediate fixes and longer-term UX strategy.
In 2021 Cyber-Duck acquired Heurix, a web application that automates UX evaluations by rating navigation, content, forms, search and other interface elements, which helps the team produce consistent evaluation reports quickly. Clients referenced on its audit page include the College of Policing, the Cabinet Office and Health Education England, and the wider site lists the Bank of England, Sport England and the Financial Ombudsman Service.
Best for: Public sector bodies, regulators and membership organizations that need an accessibility-plus-UX audit from a supplier used to government procurement.
7. DOOR3 — Heuristic UX Audits For Enterprise Workflows With Effort And Impact Roadmaps
DOOR3 is a New York design and development firm founded in 2002 that runs UX audits as a dedicated service line from its UX design practice. The audit is aimed at products where usability problems live inside complex workflows: internal platforms, B2B portals and data-heavy applications.
The engagement follows five steps: preparation and planning, research and data collection, evaluation and analysis, deliverables and recommendations, and a strategic roadmap presentation. Methods include heuristic evaluation, user research such as surveys and usability studies, competitive analysis, user flow mapping, information architecture review, content and visual design assessment, and a technical review of functional elements and performance.
Deliverables include heuristic findings, a competitive analysis report, personas and user flow diagrams, site maps, and a prioritization matrix that ranks recommendations by effort and impact. Clients named on its site include AIG, PepsiCo, Johnson & Johnson, Elsevier and Munich RE.
Best for: Enterprise teams in New York and beyond that want a UX audit company able to move from findings into design and build.
8. Neontri — Five-Week UX Audits For Banking Apps With Developer-Ready Handoff
Neontri is a Warsaw software company founded in 2013, with an additional office in Amsterdam, that works mainly with banks, fintech, insurance and retail. Its UX audit is a structured five-week engagement designed to end in work developers can start on, not just a slide deck.
Week one covers kickoff and stakeholder interviews. Weeks two and three are a deep-dive analysis combining heuristic evaluation, competitor analysis, user behavior data and visual design review. Week four validates findings through usability testing with real users, and week five is final delivery and presentation. The output has five parts: an executive summary for decision-makers, customer journey maps and performance scorecards, testing documentation, a prioritization matrix with an updated product backlog, and a developer handoff listing specific design and development tasks.
The audit page cites work with Polish banks PKO and Pekao, including a retail banking app whose store rating rose from 3.9 to 4.5, and with WP’s email platform. Other clients shown include Visa, Allegro, mBank and Decathlon.
Best for: Banks, fintechs and large retail apps in Europe that want a UX audit with built-in user validation and a backlog-ready handoff.
9. SiteTuners — Live 90-Minute CRO Expert Review With A Recorded Walkthrough
SiteTuners is a conversion rate optimization firm in Tampa, Florida that has been working on landing pages and website usability since 2002. Among its audit options, the CRO Expert Review is one of the most clearly productized UX review services on the market.
The review is a live, 90-minute video session with one of SiteTuners’ Directors of Optimization. Before the call, the client answers discovery questions about the business, site and goals. During the session, the director works through visual design and first impressions, headlines and copy, calls to action, trust elements, navigation logic, ease of use and the flow across key pages, while the client team asks questions in real time. The recording is delivered afterward so the whole team can replay it and plan fixes.
The published price is $1,097 with a seven-day satisfaction guarantee, and SiteTuners also offers fuller CRO audits and ongoing conversion programs for clients who want more depth. Clients named on its site include Google, Kodak, Nestlé, Canon and Expedia.
Best for: Small marketing teams and founders who want an interactive website UX audit from a senior conversion specialist without a multi-week engagement.
Invesp is a Chicago conversion optimization company that has been operating since 2006. Its Conversion Rate Audit is a fixed six-week program built for businesses that want expert diagnostics without signing up for a long retainer.
Weeks one and two cover discovery: a marketing review, a site walkthrough, analysis of analytics, heatmaps and session recordings, and an expert evaluation of the conversion funnel. Weeks three and four move into research and testing, with competitive benchmarking, on-site polling surveys, usability testing and performance analysis. Weeks five and six turn the findings into prioritized hypotheses and a final presentation with an actionable roadmap.
The audit assesses site design, navigation and analytics configuration, evaluates the value proposition and messaging, and identifies conversion bottlenecks and friction. It also delivers tailored A/B testing ideas, and Invesp offers post-audit guidance on quick wins, analytics fixes and test deployment. Clients shown on its site include eBay, Target, Saatva and BarkBox.
Best for: Ecommerce and lead generation businesses that want a UX audit with user research baked in and a testing roadmap at the end.
How To Choose A UX Audit Company
What Should UX Audit Services Deliver?
A useful audit deliverable has five parts. First, a clear statement of scope: which pages, flows and devices were reviewed, and against what standard (named heuristics, a research-based guideline set or WCAG). Second, an issue log in which every finding has a screenshot, a location and a severity rating. Third, evidence behind each finding, whether that is analytics data, session recordings, test sessions or a cited guideline. Fourth, a prioritized roadmap that ranks fixes by impact and effort, so your team knows what to ship first. Fifth, a walkthrough with your stakeholders. If a UX audit company cannot show you a sample report with these elements, expect a slide deck of opinions rather than a work plan.
Do You Need A Heuristic Evaluation Or An Audit With User Testing?
Heuristic evaluation services are fast and affordable because experts review the product without recruiting participants. They work well for finding obvious friction, inconsistent patterns and accessibility gaps. If the stakes are higher, or your users are specialists whose behavior is hard to predict, choose an audit that adds usability testing to validate the findings, as Neontri and Invesp build into their programs. For deeper discovery work, a dedicated usability testing agency may be the better fit.
Does The Firm Know Your Kind Of Product?
An ecommerce UX audit needs auditors who understand product listing pages, filters, checkout fields and payment trust. A SaaS onboarding audit needs people who understand activation metrics and in-app guidance. A healthcare or banking product brings compliance constraints. Ask for audit examples from your sector, and ask which benchmarks the team uses. Retail-specific research libraries and fintech case studies are strong signals that the reviewers will not waste time learning your domain.
Is The Audit Tied To Conversion Or Accessibility Goals?
Be clear about why you are commissioning the review. If revenue is the goal, look for a UX audit agency that pairs usability findings with funnel analysis and turns recommendations into A/B test ideas. If legal exposure or public sector rules are the driver, choose a firm that includes WCAG checks in the audit and can document them.
How Will The Findings Get Implemented?
An audit only pays off once fixes ship. Ask whether the firm offers follow-up calls, design mockups or a developer handoff, and whether it can carry the work into a redesign. Teams planning a rebuild may also want to compare product design agencies or, for marketing sites, SaaS website design agencies that can act on a website UX audit directly.
What Should You Expect To Pay?
Pricing for UX review services ranges widely. Productized critiques of one to three pages cost a few hundred to a few thousand dollars. Fixed-fee audits of a full site or app typically sit in the mid four figures, and multi-week audits with user testing, benchmarking and stakeholder workshops cost more. Compare on scope and deliverables rather than headline price: a cheap audit that covers only the homepage will not explain why checkout is leaking revenue.
Conclusion
The best UX audit services share a few traits: a stated method, a defined scope, findings backed by evidence and a roadmap your team can act on the following sprint. Within that, the firms here differ in what they are built for, from research-scored ecommerce UX audits and fixed-fee website reviews to accessibility-led public sector audits and heuristic evaluations of legacy enterprise software.
Start by deciding what the audit must answer, whether that is lost revenue, onboarding drop-off or accessibility risk. Then ask two or three firms for a sample report and a scoped quote. The one whose sample you could hand straight to your developers is usually the right UX audit company to hire.
