How we deliver
Architects with twenty years behind them, and a delivery process instrumented by AI: scoping, code review, quality and security tooled at every phase. Each step produces concrete deliverables, and we stay through the run.
Payment & checkout audit
Analyze your current payment tunnel: acceptance rate, abandonment rate, fraud, processing costs. Identify friction points and optimization opportunities.
- Checkout funnel analysis (abandonment rate by step, device, country)
- Acceptance rate audit by issuer and card type
- Processing cost analysis (interchange, scheme fees, PSP fees)
- Fraud risk and current filtering rules assessment
- PCI DSS compliance audit (scope, SAQ, compensating controls)
- PSP benchmark (Adyen, Stripe, Checkout.com, Mollie)
- Recommendation report with quantified business case
Payment architecture & design
Design the target payment architecture: PSP integration, multi-currency management, payment method orchestration, anti-fraud strategy.
- Target payment architecture (authorization, capture, refund flows)
- Optimized checkout design (conversion-first, mobile-first)
- PSP integration specifications (API, webhooks, tokenization)
- Multi-currency and multi-payment method strategy
- Anti-fraud rules design (risk scoring, dynamic 3DS)
- PCI DSS compliance plan (scope reduction via tokenization)
- Reporting and reconciliation specifications
Integration & PCI DSS certification
Implement the PSP integration, develop the optimized checkout, configure anti-fraud rules, achieve PCI DSS compliance. Load testing and validation with acquirers.
