Accessibility Testing Tool for Agencies – What to Look for Before You Buy

There are plenty of accessibility testing tools out there, built for different use cases and aimed at different users, from solo developers to in-house teams to large enterprises.

But if you run an agency, choosing one is a different exercise altogether. You are not buying for a single website. You are buying for a whole roster of client sites that grow and change all year.

This guide covers what to look for in an accessibility testing tool for agencies before you buy: the features that matter most at agency scale, and the questions to ask each vendor before you commit.

Features to look for in an accessibility testing tool for agencies

Not every accessibility testing tool is built for the way an agency works. Most are designed for a single website, so the moment you run one across a roster of client sites, the gaps show. As an agency, your decision comes down to a few practical questions.

Before you commit, you want to know:

• Can I manage every client from one dashboard?
• Can I schedule scans the way each client wants, and still run them on demand?
• Can I send client reports under my own brand?
• Will the plan flex with my client count instead of locking me in?
• Can I add and remove client sites myself as my roster changes?

The five features below answer each of these in turn, and show what to check before you commit.

#1. One dashboard for all your client sites

The core requirement is simple: add every client website to a single account, then switch between them to see each site’s own dashboard.

This matters because an agency lives in this dashboard every day. Being able to check one client’s status, then flip to the next in a click, is the difference between a tool that saves you time and one that adds admin overhead.

When you compare tools, check two things:

• Do all client sites live under one login with a fast site switcher?
• And does each site still keep its own separate dashboard and report view, so one client’s data never gets mixed up with another’s?

WebYes Accessibility is built around exactly this. You manage each client as an organisation and add their websites under it, all from one login. Each organisation keeps its own websites, team members, and reports separate from the rest.

#2. Scheduled scanning, controlled per client site

When you manage a handful of client sites, you can get away with starting a scan manually whenever you remember. When you manage 20 or more, that approach falls apart. Someone eventually forgets, and a site goes months without a check.

Scheduled scanning fixes this. You set the frequency you want, monthly or quarterly, once, and the tool runs the scans automatically across every client site on your roster. Nothing depends on someone remembering to click “scan.”

But a standard schedule has its limits because no two clients have the same needs. Some sign up for periodic scanning, a monthly or quarterly check they expect as part of the retainer. Others only want a scan on demand when they ship a change or ask for a fresh report.

So two things to confirm with a vendor:

• Can you set the scan frequency independently for each site, so every client matches the cadence they agreed to?
• Can you still trigger a scan on demand at any time, on top of whatever schedule is set?

WebYes Accessibility lets you set a recurring schedule per site and run an on-demand scan whenever a client needs one.

#3. White-label reporting under your own brand

Client-facing agencies need reports that carry the agency’s own branding, not the vendor’s. A report headed with a stranger’s tool name and logo undermines the relationship you’ve built with your client, right when you’re trying to show them the value of your work.

Before you commit to a tool, check the following:

• Can you replace the logo and color scheme with your own?
• Can the vendor’s name be removed from the report, if present?
• Is white-labeling included in a plan that fits your needs, or does getting it mean paying for an add-on or jumping to a higher tier than you actually need?

WebYes Accessibility provides white-label reporting on every plan tier, so you are not pushed to a higher plan to get it. You can add your own logo and set the primary and secondary colors so client reports go out looking like your agency’s work.

#4. Flexible or custom plans that scale with your roster

Your client count is never static, so your plan should not be either. The pricing model to look for is one that lets you scale up when you win clients and scale back down when you lose them, without penalty and without a renegotiation each time.

That usually means one of two things:

• a flexible tiered plan you can move between month to month, or
• a custom agency plan sized to your roster with room to adjust.

What you want to avoid is a rigid annual commitment locked to a fixed number of sites, because it leaves you either paying for capacity you no longer use or scrambling for an upgrade the moment you onboard a new client.

Two questions tell you quickly whether a plan is flexible enough:

• Can you add sites mid-cycle without jumping to a far more expensive tier?
• Can you reduce your plan when a client leaves, or are you locked in until renewal?

It also helps to know what a plan actually limits, because most tools fall into one of two models.

Domain-limited plans cap the number of sites you can add: simple to reason about, but you hit a wall each time you take on more clients than the tier allows.

Unlimited-domain plans instead cap the pages you can scan per month, so you can add as many client sites as you want and budget by total pages rather than site count.

Which model suits you depends on the shape of your roster. A smaller number of large sites may never bump a domain limit, but could burn through a page cap. Many smaller client sites usually fit the unlimited-domain model better, since no single client eats much of your monthly allowance.

WebYes Accessibility uses that second model: unlimited domains with a cap on monthly scan credits, where one credit scans one page. You add every client you manage and budget by pages scanned, never by a domain count you keep bumping into.

#5. Self-serve add and remove of client sites

Client rosters churn constantly, so adding a new client site or removing one you no longer serve should be something you do yourself in a few clicks. It should never require a support ticket, a sales call, or a contract amendment.

A tool that makes you wait to add a site slows down onboarding, and one that makes it hard to drop a site means you keep paying for clients you no longer have.

Think of this as the operational side of a flexible plan. Pricing that scales up and down only helps if you can actually make the change yourself: add a site the day you win the client, remove it the day you part ways, and see your usage adjust to match, without emailing anyone to do it for you.

A few questions tell you whether a tool really gives you that control:

• Can you add and remove sites yourself from the dashboard, or does it go through the vendor?
• When you remove a site, does your usage or billing free up, or do you keep paying for it until renewal?

With WebYes Accessibility, you add and remove client organisations and websites yourself, with no ticket or sales call needed. And because plans are based on monthly scan credits, not website count, there is no site limit to hit and nothing extra to pay when your roster changes. Your usage tracks the pages you scan, not the number of sites in your account.

Accessibility testing tool evaluation checklist for agencies

Keep this next to you when you compare tools or talk to a vendor.

• One dashboard for all client sites: manage every client from one login, with each kept separate, instead of juggling 20 accounts.
• Per-site and on-demand scanning: set each client’s scan cadence and still scan on demand, so no site slips through unchecked.
• White-label reporting: client reports go out under your brand, not the vendor’s, protecting the relationship you own.
• Flexible plans, no contract lock-in: scale up and down with your roster, and know whether the plan limits domains or pages.
• Self-serve add and remove of sites: add or drop client sites yourself in a few clicks, with your usage and billing adjusting to match.
• Integrations matched to who remediates: a Jira or PM push if your team fixes issues, a clean export or handoff if the client’s team does.
• Role-based access and permissions: give team members, and sometimes clients, the right level of access as your team grows.
• Historical trend reporting: show clients progress over time and demonstrate the value of an ongoing retainer.
• Standards coverage: confirm it tests against the standard your client is held to, such as WCAG 2.2, Section 508, or EN 301 549.
• Responsive support: when a client is waiting on a report, and something breaks, you need fast help, not a slow ticket queue.

This checklist is not exhaustive, just the features that matter most for an agency. Depending on your clients and how your team works, some rows will weigh more heavily than others, so add what fits your situation and drop what does not.

Choosing with confidence

The right accessibility testing tool for your agency depends on various factors, including how many client sites you manage, how your team works, and the kind of clients you serve.

Run your shortlist through the checklist, ask each vendor the direct questions, and pay attention to the ones who answer plainly.

Above all, be aware of what these tools cannot do. Every automated tool, WebYes Accessibility included, catches only a portion of WCAG issues, and the rest needs a human.

Do not present an automated scan to a client as proof of full compliance, and keep a manual review in place for the sites where the legal or reputational risk is real.

A tool that helps you manage accessibility across your roster is worth a lot, as long as you are clear with clients about where its job ends and a manual audit begins.
