The verdict in three sentences
A WCAG 2.1 AA-compliant citizen portal for a public administration costs USD 45,000 to 120,000 in 2026, e-services and bilingual support included. Accessibility and the security audit are not options: they carry 25-35 % of the budget and gate go-live. Expect a 14-to-20-week timeline, hardened CSP headers and an availability SLA for a public service.
How a public portal breaks down
A public-sector project lead must justify every line to oversight. Here is where the budget goes.
| Line item | 2026 range (USD) | Share |
|---|---|---|
| UX design + accessible design | 9,000 - 20,000 | 20 % |
| Build + governed CMS | 11,000 - 26,000 | 24 % |
| WCAG 2.1 AA accessibility + audit | 8,000 - 18,000 | 18 % |
| E-services (forms, tracking) | 9,000 - 24,000 | 22 % |
| Bilingual support (incl. RTL) | 4,500 - 11,000 | 10 % |
| Security audit + CSP headers | 3,500 - 9,000 | 6 % |
A mid-size administration lands near USD 78,000 for a full portal. E-services and accessibility are the two items that turn a brochure site into a genuine digital public service.
The real cost of accessibility and security
These two items are often underestimated. Here is what they concretely cover.
| Service | 2026 range (USD) | Deliverable |
|---|---|---|
| Initial accessibility audit | 2,800 - 6,500 | WCAG/508 report |
| Compliance remediation | 4,500 - 11,000 | Contrast, keyboard nav, ARIA |
| Accessibility statement | 900 - 2,200 | Mandatory document |
| Security audit (pentest) | 2,800 - 6,500 | Vulnerability report |
| CSP headers + hardening | 1,500 - 3,800 | Server configuration |
| Editor accessibility training | 1,500 - 3,300 | Session + guide |
Together, accessibility and security represent USD 21,000 to 43,000. It is the price of legal compliance and citizen trust: an inaccessible public portal exposes the administration to litigation and excludes part of its users.
Mini case study
Ms. Alaoui, digital project lead at a public administration, must deliver a citizen portal with three e-services (certificate request, appointment booking, complaint). Scope: WCAG 2.1 AA, bilingual, CSP headers, SLA. Accepted quote: USD 85,000 + USD 10,000/year maintenance. The three e-services absorb 40 % of front-desk requests, an estimated relief of 1,200 visits/month. At 15 minutes of processing per visit, the administration reclaims the equivalent of 300 agent-hours per month, redeployed to complex cases.

FAQ

How much do e-services cost?
Between USD 9,000 and 24,000 depending on the number and complexity of procedures (forms, attachments, case tracking). It is the item that creates the most citizen value and relieves the front desk.
Does bilingual support complicate the project?
Yes, if it includes an RTL language, the layout must be fully re-mirrored. Budget USD 4,500-11,000, to plan at design stage, not after.
What security level for a public portal?
Security audit (pentest), CSP headers, encryption, backups and an availability SLA. Together USD 8,000-19,000, non-negotiable once personal data flows.
What is the timeline for a citizen portal?
Between 14 and 20 weeks in 2026, accessibility and e-services being the longest phases to test. A shorter timeline signals reduced scope or rushed compliance.
