Merchant Systems
Acquiring, gateway, vault, and the modern merchant stack.
Overview
The merchant payment stack spans acquiring, gateway, vault, fraud, dispute, and reconciliation. The strategic question for any merchant above a certain GMV is no longer 'which processor' but 'how do I orchestrate across multiple processors' - to optimize approval rates, manage cost, and reduce concentration risk.
Payment orchestration platforms have emerged as a category dedicated to that orchestration, sitting between the merchant and a portfolio of underlying providers.
Key concepts
Acquiring
The merchant's bank relationship that allows it to accept card payments.
Gateway and vault

Payment orchestration
A platform layer that routes transactions across multiple PSPs to optimize approval, cost, and resilience.
Reconciliation
Matching transaction events to settlements to bank-account credits - a non-trivial accounting problem at scale.
