Account-to-account (A2A) payments

How A2A payments work

A2A payments move money using established domestic or international clearing systems. Instead of routing through card schemes, a payment instruction is sent to a bank, which then executes the transfer via a specific payment rail based on geography and urgency. Common examples of these rails include:

‍

• Europe: SEPA Credit Transfers and SEPA Instant.‍
• United Kingdom: Faster Payments and BACS.‍
• United States: ACH and Fedwire.‍
• Global: SWIFT-based wires for cross-border transfers.

Because these transactions move directly between accounts, they provide a well-defined settlement lifecycle that is essential for accurate reconciliation and cash positioning.

A2A vs. card-based payments

Unlike card payments, A2A transfers do not involve interchange fees or card issuers, making them significantly more cost-efficient—especially for high-value or recurring corporate flows. Additionally, A2A payments settle directly into the bank account, reducing the administrative complexity of chargebacks and settlement delays typical of card schemes.

Treasury use cases and liquidity management

A2A payments are the foundational building block of corporate finance, used for:

‍

• Operations: Supplier payouts, payroll, and tax payments.‍
• Liquidity: Moving funds between group entities or centralizing cash.‍
• Scalability: Managing high-volume disbursements across multiple regions.

For treasury teams, these payments are central to liquidity planning. Since each rail has its own cut-off times and settlement windows, clear visibility into A2A flows is necessary to maintain accurate cash forecasts and make informed funding decisions.

Managing A2A complexity

Modern finance environments often require orchestrating multiple A2A rails across different banks and currencies. This complexity demands a centralized approach to approvals, data standardization, and bank connectivity. Rather than managing each bank portal individually, finance teams increasingly use orchestration layers to ensure each transaction uses the most efficient rail while maintaining group-wide control.
