Payments & Banking Infrastructure Advisory

Advisory on the infrastructure, counterparties and commercial terms that sit underneath a financial product.

The problem this work solves

Payment and banking infrastructure decisions are usually treated as technical. They are commercial. The choice of acquirer, payment service provider, banking partner or settlement model determines unit economics, cash flow, redundancy and how quickly a product can be launched in a new market.

Wernberg & Partners advises on those decisions with a view of both sides: what the infrastructure has to do, and what it costs commercially over time. That includes assessing partners, designing the stack, and running the negotiations that decide the terms.

Typical situations

When companies bring us in

  • A banking or acquiring relationship is being onboarded, renegotiated or at risk, and the business needs an assessment before committing.

  • Processing costs, settlement terms or reserve requirements are eroding margin and it is unclear which part of the stack is responsible.

  • A single acquirer or banking partner represents concentration risk and a second route is being considered.

  • A new market or product requires local payment methods, local settlement or a different banking structure.

  • A payments setup grew organically and now needs to be documented, rationalised and priced properly.

Scope

What we work on

Payment-stack design

How acquiring, gateways, orchestration, payment methods and payout rails fit together for the product, the geography and the risk profile.

Banking partners

Assessing banking partners and their appetite, structure, operational reality and commercial terms against what the business actually needs.

Acquiring and PSPs

Acquirer and payment service provider selection, multi-acquirer strategy, routing logic and the commercial and risk implications of each.

Settlement models

Settlement timing, currency handling, reserves, rolling holdbacks and the effect on working capital.

Treasury considerations

Flow of funds, account structure, liquidity and how funding and payout cycles interact with commercial commitments.

Partner assessment

Structured evaluation of counterparties across commercial terms, operational capability, risk posture and durability of the relationship.

Commercial negotiations

Preparing and running negotiations on pricing, terms, service levels and exit conditions, with the benchmarks that make the position credible.

Unit economics

Translating the stack into a per-transaction and per-customer economic picture that commercial and finance teams can plan against.

Engagement

How the engagement works

01

Current state

Mapping the existing stack, counterparties, terms and costs, including what is contractually committed.

02

Assessment

Where the setup is commercially weak, operationally fragile or over-concentrated, and what the alternatives realistically look like.

03

Execution

Partner sourcing, introductions where appropriate, negotiation support and structuring the transition.

04

Continued involvement

Support through onboarding and the first operating period, when most assumptions get tested.

Selected work

Engagements of this type

  • Structuring financial infrastructure

    Assessing banking, acquiring, payments and digital-asset counterparties to create a commercially stronger and more resilient setup.
