How we work
We're on your side of the table.
Rather than representing a single processor, we operate as an advisory layer between your business and a fragmented payments ecosystem.

Where the rules are set
The methodology
Assess → Architect → Place → Optimize.
01Assess
Understand the merchant's current payment infrastructure, economics, risk profile, constraints and objectives.
02Architect
Design an acquiring and payments strategy around resilience, performance, scalability and redundancy.
03Place
Identify and evaluate appropriate acquiring, processing, banking, gateway and risk partners.
04Optimize
Continuously evaluate approval rates, costs, reserves, chargebacks, routing and overall payment performance.
Engagement models
Three ways merchants engage us.
Advisory
Independent analysis of acquiring strategy, payments architecture, economics, risk and performance.
Placement
Structured evaluation and introduction to appropriate acquiring, processing, banking, gateway and risk partners.
Ongoing Advisory
Continued oversight of payment performance, provider relationships, redundancy and infrastructure as the business scales.
Why independence matters
Independent advice. Built around the merchant.
Independence
Recommendations based on the merchant's requirements rather than a single processor or acquiring platform.
Specialization
Focused on businesses where payments are complex, regulated, high-risk, high-growth or operationally critical.
Continuity
Infrastructure designed to reduce dependency on any single acquiring or processing relationship.
Greyhaven may maintain commercial relationships with certain payment providers. Where applicable, these relationships and potential compensation are disclosed to clients.
Merchant-aligned by design.
Because we work across multiple acquiring and banking relationships, the recommendation can follow your requirements rather than a single provider's underwriting box.
