TLDR
Most WCAG compliance tools assume a single organization managing its own sites. Multi-client management — separate reporting per client, a portfolio-wide health view, and pricing that doesn't compound per site — is rare in the category. These are the tools worth evaluating if you manage accessibility across more than one client.

| Deque WorldSpace | Yes (enterprise) | No | Custom enterprise | Source scanner |
| Pope Tech | Yes | No | Custom (education) | Source scanner |
| Siteimprove | Workaround | No | Custom enterprise | Digital quality platform |
| accessiBe Partner | Widget management only | No | Per-site partner rate | Overlay widget |

accessiBe Partner Program
accessiBe's reseller program allows agencies to install accessiBe overlays on client sites at partner pricing. Not a scanner — a per-site overlay subscription.
Pros
- ✓ Centralized partner dashboard for managing client installations
- ✓ Volume discounts available through partner program
- ✓ Fast deployment across client sites
Cons
- × Overlay model — no source-level WCAG remediation or documentation
- × Per-site billing still compounds at portfolio scale

Pricing: Partner discount off $49-$199/site/mo
Verdict: Not a WCAG compliance tool — an overlay widget reseller arrangement.

See plans & pricingThe multi-client accessibility management market is thin. Most tools assume you own the sites you’re scanning. The product design, reporting, billing, and account structure all reflect that assumption.
Agencies need the opposite: a tool where each client is a distinct entity, reports are client-branded and client-deliverable, and pricing doesn’t require multiplying by your client count.
This comparison covers tools where multi-site or multi-client management is at least theoretically possible. It includes honest assessments of which tools require workarounds vs. which support agency workflows natively.
The entry on accessiBe’s partner program is included specifically to draw a distinction: a widget reseller dashboard is not a WCAG compliance tool. Agencies that evaluate accessiBe’s partner program as a multi-client accessibility solution should understand what the product does and does not provide before recommending it to clients under an accessibility compliance framing.
Q&A
What is the best WCAG compliance tool for multi-client management?
A11yProof is the only tool in this comparison purpose-built for agency multi-client management: native per-client account structure, portfolio health dashboard, white-label reporting, and flat portfolio pricing at $29/month. Enterprise alternatives like Deque WorldSpace Attest offer multi-site management but require custom contracts.
Q&A
How do agencies currently manage WCAG compliance across multiple clients?
Most agencies use a combination of axe browser extension for spot-checking, manual Lighthouse audits, and ad-hoc tools. The common pattern is no systematic approach — audits happen at launch, ongoing monitoring doesn't, and clients don't receive regular compliance reports. This is the gap A11yProof is designed to fill.
