eIDAS vs Traditional KYC: A Cost and Conversion Analysis

Corrected 20 October 2026: an earlier version of this post used outdated eIDAS Pro prices (€29 / €99 / €299 per month). The current plans are Starter at €79 (75 verifications included), Standard at €279 (350 included) and Scale at €679 (1,000 included), and every cost table has been recalculated; the year 2 and year 3 figures now keep the lost-revenue line on both sides. We also removed features eIDAS Pro does not offer (all 27 national eID schemes, 21+ and 25+ thresholds, residency, watchlist and address checks): the live route today is bank eID (iDIN) with a fixed 18+ check, and EUDI Wallet verification is not yet available in production. The conversion figures are illustrative assumptions, not measured eIDAS Pro customer data, and the ROI-by-business-size and sensitivity tables, which rested on unsourced estimates, were removed.

The True Cost of Traditional KYC

When evaluating identity verification solutions, most businesses focus on per-transaction pricing. This approach dramatically underestimates the true cost of traditional KYC (Know Your Customer) processes. A comprehensive analysis must account for setup costs, ongoing operations, conversion impact, and hidden expenses that only become apparent after implementation.

Setup and Integration Costs

Traditional KYC platforms require significant upfront investment:

Technical Integration

Operational Setup

Combined Setup Investment: €32,000-123,000

For many SMBs, this initial investment represents a significant barrier. The cost must be amortized over the expected verification volume—meaning low-volume merchants face disproportionately high per-verification setup costs.

Per-Verification Costs

Traditional KYC pricing typically follows a tiered model:

What's Not Included in Base Pricing

Most traditional KYC vendors charge extra for:

• Manual review escalation: €3-10 per review when automated checks fail
• Additional document types: €0.50-2.00 per additional document
• Database checks: €0.25-1.00 per sanctions/PEP/watchlist check
• Address verification: €0.50-2.00 per address check
• Ongoing monitoring: €0.10-0.50 per profile per month
• API overage fees: Often 150-200% of standard rate
• Support tiers: €500-5,000/month for priority support

Staffing and Manual Review Costs

Traditional KYC generates significant manual review workload:

Manual Review Requirements

Automated document verification typically achieves 70-85% straight-through processing (STP). The remaining 15-30% require human review:

Staffing Cost Calculation

For a merchant processing 10,000 verifications per month with 20% manual review:

Manual reviews required: 2,000/month
Average review time: 5 minutes
Total review hours: 167 hours/month
FTE required: ~1.0 (at 160 working hours)

Fully-loaded cost per FTE: €45,000-65,000/year
Monthly staffing cost: €3,750-5,400
Cost per manual review: €1.90-2.70

This staffing cost often exceeds the base verification fees.

Infrastructure and Compliance Costs

Document-based KYC creates ongoing infrastructure requirements:

Data Storage

Personal data (ID images, selfies, extracted PII) must be stored securely:

Compliance Overhead

Hidden Costs: Conversion Rate Impact

The most significant cost of traditional KYC isn't in the vendor invoices—it's in the customers who abandon your checkout flow.

Abandonment Statistics

Research across e-commerce platforms reveals consistent patterns:

Compounded Abandonment

For a multi-step verification process, abandonment compounds:

Starting customers: 1,000
After ID upload request: 800 (20% drop)
After document capture: 680 (15% drop)
After selfie check: 608 (10% drop)
After manual review wait: 456 (25% drop)

Net completion rate: 45.6%
Lost customers: 544 per 1,000 attempts

Cart Recovery Failures

Traditional KYC's timing creates additional friction:

Verification at Checkout

When verification happens at checkout, customers have already decided to purchase. Friction at this point has maximum impact:

Pre-Purchase Verification

Some platforms verify during account creation. This shifts abandonment earlier but creates other issues:

• Verification costs incurred for users who never purchase
• User data collected that may never be used
• Stale verifications may require re-verification at purchase

Mobile Conversion Challenges

Traditional document verification performs poorly on mobile devices:

With mobile commerce exceeding 60% of e-commerce transactions, these challenges represent a massive conversion tax.

eIDAS Cost Structure

eIDAS-based verification offers a fundamentally different cost model:

Transparent Per-Verification Pricing

eIDAS Pro pricing is straightforward:

What's Included

• Bank eID age verification (iDIN), live today; EUDI Wallet verification once WRPAC certificates can be obtained
• An 18+ check (the threshold is currently fixed at 18+ for every merchant)
• A yes/no result only: no date of birth and no ID scan reaches your systems
• Real-time SSE status updates
• Client dashboard with usage tracking
• Verification results reusable for 30, 90 or 365 days (Starter, Standard, Scale)
• Webhooks on the Scale plan
• No manual review fees (fully automated)
• No document images to store
• No additional document fees

Minimal Setup Costs

eIDAS integration is dramatically simpler:

Why So Much Simpler?

1. No document handling: No upload UI, image processing, or quality checks
2. No data storage: Boolean results don't require secure PII storage
3. 100% automation: No manual review workflows to build
4. Standard integration: Simple REST API with pre-built SDKs
5. Minimal compliance burden: No PII = minimal GDPR complexity

No Hidden Fees

eIDAS verification eliminates entire cost categories:

Side-by-Side Comparison

Let's compare total cost of ownership for a typical e-commerce business:

Scenario: Mid-Size Retailer

Business Profile:

• Annual revenue: €5 million
• Monthly transactions: 5,000
• Verification required: 20% of transactions (1,000/month)
• Mobile traffic: 60%
• Current conversion rate: 2.5%
• Average order value: €85

12-Month TCO Analysis

Traditional KYC (Document + Selfie)

eIDAS Pro (Scale Tier)

At 1,000 verifications a month, Scale (€679, 1,000 included) costs less than Standard (€279 + 650 × €0.65 = €701.50).

Savings: €252,102 (87%)

Year-Over-Year Comparison

Setup costs drop out after year 1 on both sides; the lost-revenue line stays on both sides every year (€21,250 a year for eIDAS Pro, €127,500 for traditional KYC).

Conversion Rate Improvements

eIDAS verification dramatically improves conversion rates:

Before/After Metrics

Illustrative assumptions for this model (not measured eIDAS Pro customer data; test them against your own funnel):

Why Such Better Conversion?

Familiar Experience: Users already have their national eID app installed and regularly use it for banking, government services, and other platforms. Verification feels routine, not invasive.

No Document Hunting: Users don't need to find their physical ID, position it correctly, deal with glare, or retake photos multiple times.

Mobile-Native: eID apps are designed for smartphones. A tap, biometric authentication, and done—regardless of lighting, camera quality, or screen size.

Trust Signal: Verification through government-issued credentials signals legitimacy to users. It's the same process they use for banking.

Instant Results: No waiting for manual review. The customer completes verification and immediately continues their purchase.

Conversion Impact Calculation

For our mid-size retailer scenario:

Traditional KYC:

Customers requiring verification: 1,000/month
Verification completion rate: 52.5%
Customers verified: 525
Post-verification purchase rate: 95%
Completed purchases: 499
Revenue from verified customers: €42,415/month

eIDAS Pro:

Customers requiring verification: 1,000/month
Verification completion rate: 93.1%
Customers verified: 931
Post-verification purchase rate: 97%
Completed purchases: 903
Revenue from verified customers: €76,755/month

Monthly Revenue Difference: €34,340 Annual Revenue Difference: €412,080

Break-Even Analysis

At what volume does eIDAS become more cost-effective than traditional KYC?

Volume-Based Break-Even

Comparing direct costs only (excluding conversion impact):

Answer: on these assumptions, eIDAS Pro's direct cost is lower at every volume in the table

Traditional KYC's overhead (manual review, infrastructure, compliance) widens the gap further. At very low volumes the Starter fee dominates, so run the numbers for your own volume.

Including Conversion Impact

When conversion losses are factored in, the gap widens dramatically:

interface CostComparison {
  traditionalKyc: {
    directCosts: number;
    conversionLoss: number;  // Often 3-5x direct costs
    total: number;
  };
  eidasPro: {
    directCosts: number;
    conversionLoss: number;  // Typically 10-20% of traditional
    total: number;
  };
}

function calculateBreakEven(
  monthlyVerifications: number,
  averageOrderValue: number
): CostComparison {
  const traditional = {
    directCosts: monthlyVerifications * 3.50,  // Average per-verification
    conversionLoss: monthlyVerifications * 0.40 * averageOrderValue,  // 40% abandonment
  };
  traditional.total = traditional.directCosts + traditional.conversionLoss;

  const eidas = {
    directCosts: monthlyVerifications * 0.68,  // ≈ €679 / 1,000 on Scale; varies by plan and volume
    conversionLoss: monthlyVerifications * 0.07 * averageOrderValue,  // 7% abandonment
  };
  eidas.total = eidas.directCosts + eidas.conversionLoss;

  return { traditionalKyc: traditional, eidasPro: eidas };
}

Implementation Cost Considerations

Switching from traditional KYC to eIDAS involves transition costs:

Migration Planning

Handling Non-EU Customers

For customers without EU eID wallets, hybrid approaches work well:

async function selectVerificationMethod(
  customer: Customer
): Promise<VerificationMethod> {
  // Check if customer likely has EU eID wallet
  const hasEuWallet = await checkEuWalletAvailability({
    country: customer.country,
    ipGeolocation: customer.ipLocation
  });

  if (hasEuWallet) {
    return {
      method: 'EIDAS',
      provider: 'eidas-pro',
      expectedConversion: 0.93,
      cost: 0.68
    };
  }

  // Fallback for non-EU customers
  return {
    method: 'DOCUMENT',
    provider: 'legacy-kyc-provider',
    expectedConversion: 0.55,
    cost: 3.50,
    recommendation: 'Consider limiting non-EU age-restricted sales'
  };
}

Sunk Cost Considerations

If you've already invested in traditional KYC, consider:

Write-Off vs. Ongoing Loss

Scenario: €50,000 invested in traditional KYC integration

Option A: Continue using traditional KYC
  Annual ongoing cost: €100,000
  5-year total: €500,000

Option B: Switch to eIDAS Pro
  Migration cost: €10,000
  Annual ongoing cost: €10,148 (€8,148 Scale subscription + €2,000 compliance)
  5-year total: €60,740

Net savings by switching: €439,260
Payback period: 1.3 months

The sunk cost of existing integration is irrelevant to the forward-looking decision. The mathematics favor switching regardless of prior investment.

Long-Term ROI Projections

3-Year Projection

For our mid-size retailer scenario:

Lost revenue from abandonment is already inside both cost lines, so the conversion upside calculated earlier is not added on top.

Testing the Assumptions

Most of the gap comes from the conversion assumptions (30% versus 5% abandonment), not from the subscription price. Replace them with your own funnel data before you rely on the result: the direct-cost advantage alone holds at every volume in the break-even table above, but the size of the total saving depends on how many customers your current flow actually loses.

Conclusion

The comparison between traditional KYC and eIDAS-based verification is stark:

Traditional KYC:

• High setup costs (€25,000-100,000)
• Complex ongoing operations
• Significant conversion losses (30-50% abandonment)
• Growing compliance burden
• Increasing fraud risk as deepfakes improve

eIDAS Pro:

• Minimal setup (€2,000-10,500)
• No manual review operations
• Higher expected completion (93% in this illustrative model)
• Simplified compliance (no PII)
• No document images to forge or deepfake: the result comes from an authenticated eID

The business case extends beyond cost savings. eIDAS verification positions your business for the future of European digital identity. As eIDAS 2.0 and the EU Digital Identity Wallet roll out across member states, early adopters will have established infrastructure and customer familiarity that provides lasting competitive advantage.

For any business operating in the EU market with age verification, KYC, or identity requirements, the question isn't whether to adopt eIDAS—it's how quickly you can migrate.
