The verdict in three sentences
Web accessibility is no longer a nice-to-have: it is an obligation that gates access to public tenders and shields against penalty risk. In 2026, WCAG 2.1 AA compliance costs USD 4,000-12,000 depending on size, plus USD 2,000-5,000 for the audit. The economic lesson is clear: building accessibility in from design costs 3-5x less than fixing it afterward.
What accessibility compliance covers
WCAG 2.1 level AA sets the bar. Compliance touches code, content and process. Here are the main items and their 2026 cost.
| Item | What it involves | 2026 cost (order of magnitude) |
|---|---|---|
| Initial audit | Status vs WCAG 2.1 AA | USD 2,000-5,000 |
| Technical fixes | Contrast, keyboard nav, ARIA | USD 2,500-7,000 |
| Text alternatives | Images, media, PDF | USD 600-2,500 |
| Accessibility statement | Mandatory legal document | USD 400-1,000 |
| Contributor training | Sustainable accessible content | USD 1,000-2,500 |
Keyboard navigation, color contrast and text alternatives concentrate most non-conformities. The accessibility statement is a legal document to publish, not a mere formality.
The cost of anticipation versus catching up
When you address accessibility changes everything. Built in from design, it is nearly painless; added to an existing site, it forces reworking code and content. Here is the decisive comparison for a corporate secretary.
| Approach | When | Typical cost | Residual risk |
|---|---|---|---|
| Accessibility by design | From design | +5 to 10% of project | Low |
| Retrofit compliance | Existing site | USD 4,000-12,000 | Moderate |
| Non-compliance | No action | USD 0 immediate | High: penalty + tender exclusion |
An inaccessible site can be excluded from public tenders (where accessibility is often a disqualifying criterion) and expose the company to complaints. The opportunity cost of a lost tender far exceeds that of compliance.
Mini case study
Fabienne is corporate secretary of a 300-employee industrial mid-cap in Toronto. The company regularly bids on public tenders where site accessibility is a scored criterion. A WCAG audit (USD 4,500) reveals a 62% compliance rate — too low to be credible.
She commissions compliance: technical fixes (USD 5,500), text alternatives (USD 1,500), statement (USD 600) and contributor training (USD 2,000). Total: USD 14,100, audit included. Against a single USD 500,000 public contract for which non-compliance would be disqualifying, the investment is under 3% of the stake — and it secures every subsequent tender.

FAQ
Is my B2B site subject to accessibility obligations?
Large companies and those bidding on public tenders are directly concerned; the scope is widening. Even without a strict obligation, accessibility is an increasingly common selection criterion among buyers.
What does an accessibility audit cost in 2026?
Between USD 2,000 and 5,000 depending on site size and depth (automated audit plus manual checks). It is the mandatory starting point to prioritize fixes.
What total budget to become compliant?
Usually USD 4,000-12,000 for a mid-cap, audit included, depending on the number of templates and the starting state. A site designed accessible from the start sharply cuts this bill.
What does a non-compliant company risk?
Exclusion from public tenders where accessibility is disqualifying, complaints and reputational harm. The cost of a lost tender almost always exceeds that of compliance.
Why build accessibility in from design?
Because retrofitting forces reworking code and content, costing 3-5x more. Planned upstream, accessibility adds only 5-10% to the project budget.
