Updating an existing Accessibility Conformance Report is typically less expensive than starting a new one, provided the prior audit data remains valid and the product has not changed substantially. When updates are minor and the underlying evaluation is recent, costs can drop to the lower end of the 300 dollar to 1,000 dollar ACR issuance range. When the product has shifted significantly or the prior audit is outdated, starting fresh often costs the same or less than reconciling stale data.
| Factor | What It Means for Cost |
|---|---|
| ACR issuance range | 300 dollars to 1,000 dollars, separate from any audit work required to support it. |
| Audit baseline | Most accessibility audits start at 1,000 dollars and range to 3,000 dollars when a new evaluation is needed. |
| Update is cheaper when | Prior audit is recent, product scope is stable, and only minor remediation has occurred. |
| New is cheaper when | Product has changed significantly, prior data is stale, or no audit report exists. |
What an ACR Update Actually Involves
An ACR update revises an existing Accessibility Conformance Report to reflect the current state of the product. The conformance claims, remarks, and explanations are revised based on what has changed since the prior issuance.
If remediation has occurred, the update reflects fewer issues and stronger conformance language. If new features were added, those areas need to be evaluated before the ACR can accurately describe them. The cost depends on how much new evaluation work the update requires.
When Updating Costs Less
An update is the less expensive path when the prior audit is recent, the product scope has not materially changed, and the changes can be confirmed without re-evaluating the full product. In these cases, the work centers on revising the document itself, which falls within the 300 dollar to 1,000 dollar issuance range.
Updates also cost less when remediation has been tracked against the original audit findings. When the issues list, remediation status, and validation are documented, the writer revising the ACR has what they need to update conformance claims accurately.
When Starting New Costs Less or the Same
Starting new often makes more sense when the prior audit is more than twelve to eighteen months old, the product has been redesigned, or significant features have been added. In these scenarios, an update would require so much new evaluation work that it approaches the cost of a fresh audit and ACR.
Starting new is also the practical option when the original ACR was issued by a different provider and the underlying audit data is unavailable or incomplete. Without access to the prior issues list and methodology, an updater is conducting a new evaluation while paying for document reconciliation on top of it.
Cost Drivers That Apply Either Way
Whether updating or starting new, several factors influence the total cost:
- Scope: number of pages or screens evaluated, and whether mobile, desktop, or both environments are included.
- VPAT edition: WCAG edition is the default for most products. Section 508, EN 301 549, and INT editions cost more because they cover additional standards.
- Audit currency: how recent the supporting evaluation is, and whether it covers the current WCAG version referenced in procurement requirements.
- Remediation status: whether issues have been fixed and validated, which determines how much of the conformance language needs to change.
How to Decide
The decision comes down to three questions. Is the prior audit recent enough to support current conformance claims? Has the product changed enough that prior evaluation data no longer reflects reality? Is the original audit data accessible and well-documented?
If the answers favor reusing prior work, updating is almost always less expensive. If the answers favor a fresh evaluation, starting new produces a more accurate ACR for roughly the same total cost as a heavily revised update.
Procurement teams reviewing an ACR care about accuracy and currency. A cheap update built on stale data can fail review, which costs more in the end than starting fresh would have.
