Door B · Businesses
Senior payments expertise, engaged directly.
For businesses that need a specific problem handled by a team with direct industry experience. We provide senior, accountable support from the first call through to delivery.
01
Payments infrastructure
Provider architecture, orchestration, tokenisation, redundancy. Build-vs-buy decisions grounded in actual industry economics.
02
International expansion
Local acquiring strategy for new markets, cross-border settlement, FX and the operational plumbing that decides whether you can bill on day one.
03
Acquirer strategy
Panel design, RFP structuring and contract benchmarking. We know what acquirers will and won't move on — and where the leverage sits.
04
Operational review
Reconciliation, chargebacks, MID structure, scheme fees, reporting. A short, direct read of where the payments function is leaking cost or risk.
How we engage
Discovery
A short paid diagnostic — usually one to two weeks — to define the actual question before committing to a scope.
Project
Fixed-scope engagement with clear deliverables and a defined end. Priced on a fixed fee.
Ongoing senior advisory
Ongoing senior advisory: monthly day allocation, board-adjacent, on call for the decisions that need it.
