The other half of Kerbcut · build · run · improve
Kerbcut analyses your website and tells you what to fix. Kerbstack is the team that does the fixing: in your theme and templates, with your approval, then keeps the site updated, monitored and improving every month. Kerbcut re-checks every fix, so you see proof instead of promises.
For online stores and B2B companies without a developer in-house. We work in English, Portuguese and Spanish.Why Kerbstack exists
accessibility rule types on the Kerbcut example store were cleared by Kerbcut's automatic fix-pack. The other 4 needed changes to the theme, colours and layout: work for a person.
Measured with axe-core 4.10.2 in Chromium, WCAG 2.x A/AA and best-practice rules, 20 Oct 2026
of B2B buyers prefer to buy without talking to a sales rep. Your website does the selling, so broken forms and slow pages cost deals you never hear about.
Gartner, survey of 646 B2B buyers, Aug–Sep 2025, published Mar 2026
of B2B buyers used AI tools in a recent purchase. Assistants can only cite what your pages say clearly and what their crawlers can read.
Same Gartner survey
The report lands in an inbox. The agency that built the site quotes from scratch, or is gone. Some fixes ship, nobody checks them, and a theme update quietly brings the problems back.
We turn each finding into a costed task, fix it in your real templates on a staging copy, ship it after your approval and ask Kerbcut to re-check the page. Then we stay: updates, monitoring, changes you ask for, and a monthly report with the evidence.
Kerbcut + Kerbstack
Each product works on its own. Together they close the loop: nothing is marked done until the same engine that found the problem stops finding it.
| Who does what | Kerbcut alone | Kerbstack alone | Kerbcut + Kerbstack |
|---|---|---|---|
| Find problems | Accessibility, page by page, with code changes | Technical, speed, SEO, AI search, conversion and accessibility audit | Both, merged into one task list |
| Fix them | Automatic fix-pack for simple cases; your developer does the rest | We do it, in your theme and templates | Fix-pack first, Kerbstack finishes what needs a person |
| Prove the fix | Re-check the pages you fixed | Our own audit before and after | Kerbcut re-checks every Kerbstack fix |
| Keep it working | Scheduled analyses and alerts | Updates, backups, uptime and form monitoring, changes on request | Regressions found by Kerbcut become Kerbstack tasks |
| Best for | Stores with a developer | Companies that need a team for the whole site | Companies with no developer that must show progress |
How it works
We audit the whole site: every page type, not just the home page. If you use Kerbcut, we start from your latest analysis.
Each finding becomes a task with an estimate, the evidence and the metric to watch. You choose what we do and when.
We fix on a staging copy and send you a link. Nothing goes live without your approval in the client portal.
Updates, backups, monitoring, your change requests, a new audit and one report that shows what changed and what it cost.

The same example store as the Kerbcut demo, in three states. Pick a stage to see the page and what the engine found on it. The numbers come from real runs of the Kerbcut engine in a browser; the pages below are the actual HTML that was tested.

What changed
axe-core 4.10.2 in Chromium, rule sets WCAG 2.0/2.1/2.2 A and AA plus best practice, run on 20 Oct 2026. Automated tests cover only part of WCAG; keyboard and screen-reader checks need a person.
What you get
Theme, layout, colours, forms, content. The work an automatic tool cannot do safely, done by a person and tested on staging.
Monthly accessibility analysis of your site with Kerbcut's engine on the Business and Growth plans, and a re-check after every fix.
Ask for changes, approve work, see incidents, reports, audits and invoices. Hours left this month are always visible.
Uptime, certificate and contact-form checks. Two failed checks in a row open an incident; you hear from us, not from a customer.
Core, theme and plugin updates with a visual check after each one, daily backups and a restore test every quarter.
Availability, incidents, work done, hours used, and what the latest audit says compared with the one before.
Pricing · EUR, excluding VAT
Every plan states its hours, its response times and what is not included. Work beyond the included hours costs €85 per hour and starts only after you approve the estimate.

Questions
No. Kerbstack runs its own audit, which includes accessibility through the Kerbcut engine. A Kerbcut subscription is useful if you want to follow accessibility yourself between our reports.
Send us your latest Kerbcut analysis. We quote a fix sprint for the findings the fix-pack could not solve, and Kerbcut re-checks each page once our fix is live.
No. Automated tests cover only part of WCAG. A clean result means the automatic checks pass; keyboard, screen reader and content checks still need a person, and legal compliance is a question for your lawyer.
You do. Domain, hosting, analytics and content stay in your name. If you leave, we hand over every access and a final backup.
We estimate first. Extra hours cost €85 each and start only after you approve them, or we schedule the work into next month.
Our software drafts first versions of reports and proposals and runs routine checks. A person reviews everything before you see it, and AI never publishes changes to your site.
Shopify, WooCommerce, WordPress, Webflow and static sites built on our components. For other platforms we start with the audit and tell you what we can maintain.
Next step
Tell us your website and what you need. You get the audit within one week, with a walkthrough call. The €490 counts toward a build or plan if you continue within 60 days. Kerbcut customers can send their latest analysis instead.
Next you create your account (one minute). Your request goes straight to our team and you follow it in your client portal. Nothing is charged until you accept a written proposal.
