1. Assess
Map the existing payment flow, system boundaries, data movement, third parties, dependencies, ownership and available evidence.
For CTOs, Heads of Engineering and Payment Leaders
Know What Could Delay, Weaken or Complicate Your Payment Architecture
Get independent challenge before an acquirer discussion, PCI DSS engagement, launch or major system change. Turn unclear boundaries, ownership questions, resilience concerns and missing evidence into a prioritised plan your engineering, security and compliance leaders can act on.

One defined payment flow · Two-week review · Five founding-client places
The review method
Understand the current state before deciding what to change.
The review follows a real payment flow from entry to outcome. Findings distinguish what is observed, what your team states, what remains uncertain and what requires confirmation from a qualified specialist.
2. Test
Challenge architecture assumptions, failure paths, recovery decisions, control ownership and evidence traceability through structured review.
3. Evidence
Record findings, decisions, evidence references, open questions, responsible owners and prioritised next actions.
What you receive
A review your teams can act on.
Outputs are prepared as working architecture and evidence-discovery records. They are designed to help engineering, security and compliance teams make decisions—not to imitate formal validation documents.
- Current-state payment-flow and boundary map
- Architecture findings register with clear classifications
- Dependency, ownership and open-question inventory
- Evidence-reference register for internal preparation
- Prioritised remediation and decision roadmap
- Executive readout and engineering handover
A good fit when
- You lead engineering, architecture or payments and need an independent view before committing to change
- A launch, migration or major payment-flow change needs independent challenge
- An acquirer conversation or PCI DSS engagement has exposed unanswered architecture questions
- Engineering, security and compliance teams disagree about boundaries or ownership
- Important architecture decisions are undocumented or difficult to evidence
Clear professional boundary: this is an architecture review and evidence-discovery engagement. It is not PCI DSS certification, a formal QSA assessment, penetration testing or legal advice. It does not promise that an assessor or acquiring institution will accept a particular artefact or conclusion.
Five founding-client places
Bring one payment flow that needs a clearer answer.
Tell me which existing payment flow needs review, what decision or external conversation creates urgency, and your target date. You will receive a clear fit decision before any engagement begins.
