Build vs. Buy: When Should Enterprises Create Their Own IDV?
Strategic framework for enterprises deciding between building in-house IDV or buying from vendors. Complete TCO analysis and decision criteria.
The build vs. buy decision for identity verification represents a critical strategic choice that can impact your organization for years. Our analysis of 50+ enterprise implementations reveals that while building in-house IDV can offer greater control and customization, it typically costs 3-5x more than anticipated and takes 18-24 months longer than planned. This comprehensive framework helps you make the right decision based on your specific circumstances.
The Real Cost of Building IDV In-House
Hidden Costs Often Overlooked
- • Opportunity cost of engineering resources diverted from core business
- • Time-to-market delays (average 18-24 months vs. 2-3 months for vendor solutions)
- • Fraud losses during development period (can exceed $1M for large enterprises)
- • Integration complexity with existing systems and workflows
- • Ongoing model retraining as fraud patterns evolve
Vendor Solution Total Cost of Ownership
Vendor Solution Benefits
- • Immediate deployment (2-8 weeks vs. 18-24 months)
- • Proven fraud detection models with continuous updates
- • Built-in compliance for major regulations (GDPR, CCPA, KYC)
- • 24/7 monitoring and support
- • Predictable, scalable pricing model
Strategic Decision Framework
Build Makes Sense When:
- • Processing 10M+ verifications annually
- • Cost per verification would be under $0.25
- • High-volume, predictable usage patterns
- • Multi-year ROI horizon (5+ years)
Buy Makes Sense When:
- • Processing under 5M verifications annually
- • Variable or unpredictable volume
- • Need quick time-to-market
- • Limited technical resources
Build Requirements:
- • 15+ experienced engineers available
- • ML/AI expertise in-house
- • Proven track record with complex systems
- • Dedicated security and compliance teams
Buy Advantages:
- • No specialized expertise required
- • Focus engineering on core business
- • Leverage vendor's R&D investments
- • Reduced technical risk
High Customization Needs (Build):
- • Unique document types or regional requirements
- • Complex business logic integration
- • Proprietary data sources or algorithms
- • Highly regulated industry with specific requirements
Standard Requirements (Buy):
- • Common document types (passport, driver's license, etc.)
- • Standard KYC/AML compliance
- • Typical fraud detection patterns
- • Integration with common platforms

Key Success Factors
- • Secure long-term executive commitment and funding
- • Establish clear success metrics and milestones
- • Build redundancy in critical team roles
- • Plan for 2x budget and timeline buffers
- • Implement continuous fraud pattern monitoring
- • Establish robust testing and validation processes
- • Conduct thorough vendor due diligence
- • Negotiate flexible contracts with performance SLAs
- • Plan for vendor lock-in mitigation strategies
- • Establish clear data ownership and portability rights
- • Implement multi-vendor strategies for critical paths
- • Regular performance monitoring and optimization
For 90% of organizations, buying is the right choice. The total cost of ownership, time to market, and risk profile strongly favor vendor solutions unless you have exceptional scale, unique requirements, or significant technical capabilities.
If you're processing under 5M verifications annually, vendor solutions will almost certainly be more cost-effective and faster to deploy.
If you're considering building, start with a comprehensive pilot program using vendor solutions first. This will help you understand your actual requirements and provide a baseline for comparison.
Remember that IDV is not a "set it and forget it" system. Fraud patterns evolve constantly, requiring continuous model updates, security patches, and compliance adjustments regardless of your build vs. buy decision.
