Optimising account-to-account payments with Cardflo bypasses traditional card networks, directly reducing interchange fees for merchants. Our platform supports efficient boarding to acquirer partners, streamlining direct bank transfers and improving overall transaction efficiency.
Account-to-account payments overview
Account-to-account (A2A) payments represent a direct method of transferring funds from a consumer bank account to a merchant account without the intermediation of card schemes. By bypassing the traditional rails provided by Visa and Mastercard, these transactions avoid cumulative interchange and scheme fees, resulting in a lower cost of acceptance for high-volume or high-ticket enterprises.
The mechanism typically relies on open banking infrastructure, where the payer authorises the transaction through their own banking application. This process uses existing bank-grade security and Strong Customer Authentication (SCA) to verify identity, which inherently reduces the risk of unauthorised transactions.
From an operational standpoint, A2A payments occupy a critical position in the payments stack by offering real-time or near-real-time settlement cycles, particularly through systems like Faster Payments in the UK or SEPA Instant in Europe. This improves liquidity management and reduces the time funds remain in transit between the acquirer and the merchant bank account.
How account-to-account payments works
Initiation at Checkout
The customer selects the bank transfer option at the point of sale. The merchant gateway generates a secure request to an open banking provider, which then presents a list of supported financial institutions. The user selects their bank, triggering a redirection to their native mobile banking application or online portal.
Authentication and authorisation
The bank validates the user identity through biometrics or two-factor authentication, satisfying PSD2 requirements. The transaction details, including the exact amount and recipient merchant ID, are pre-populated to prevent manual entry errors. The user confirms the payment within their bank's secure enviornment to authorise the transfer.
Real-time fund transfer
Upon authorisation, the bank initiates a credit transfer through regional clearing systems. Unlike card payments that involve complex authorisation and capture phases, A2A transfers move liquidity directly. The bank issues a real-time notification to the payment service provider, confirming that the instruction has been successfully queued for settlement.
Status update and reconciliation
The gateway receives the payment confirmation and updates the transaction status in the merchant dashboard. Because the funds arrive via credit transfer, the reconciliation process is simplified. The merchant receives the full transaction value, minus the flat service fee, typically arriving in the bank account within seconds.
Why account-to-account payments matters
Reduction in Transaction Overheads
Traditional card processing carries a stack of costs, including interchange, scheme fees, and acquirer margins. Account-to-account payments operate on a flat-fee or lower percentage basis because they do not utilise the expensive infrastructure of credit card networks. For businesses managing thin margins or high transaction values, this structural change significantly reduces the overall cost of payment acceptance over time.
Elimination of Chargeback Risk
A2A payments are executed as push payments, meaning the customer initiates the transfer. Unlike card payments, where merchants face the risk of chargebacks and associated fees, A2A transfers are generally final once authorised by the bank. This provides merchants with greater certainty of settlement and eliminates the administrative burden and financial loss associated with representment and dispute management.
Account-to-account payments use cases
Inventory invoice settlement
Wholesale distributors settle high-value inventory invoices by direct bank transfer, but remittance references can be truncated or separated from purchase orders across clearing networks. Cardflo provides routing and reconciliation tooling that links transfer records to invoice numbers, supplier accounts and expected settlement dates for finance teams.
Intercompany cash concentration
Corporate treasury teams move balances from operating subsidiaries into concentration accounts, where differing clearing cut-offs and settlement statuses can obscure group liquidity. Cardflo supports routing across available bank rails and consolidates transfer reporting, helping controllers reconcile originating entities, value dates and destination accounts.
Mandated software licence collections
Enterprise software publishers collect annual licence charges through recurring direct debits, requiring valid mandates, advance notices and clear handling of returns or indemnity claims. Cardflo and its acquirer partners support mandate-linked collection workflows, transaction status reporting and reconciliation against customer contracts, renewal dates and billing records.
Commercial rent reconciliation
Property operators receive monthly rent, service charge and insurance payments from commercial tenants, often as separate transfers with inconsistent property or lease references. Cardflo provides account-to-account reconciliation tooling that matches incoming funds to tenant ledgers, premises, rent schedules and arrears, while flagging short, late or unmatched payments.
Account-to-account payments by the numbers
This represents the typical reduction in processing fees when comparing A2A to standard credit card merchant service charges.
Based on clearing through UK Faster Payments or SEPA Instant, though actual availability depends on the participating banks.
Industry data indicates a near-total elimination of traditional chargebacks, as push payments rarely allow for non-fraudulent reversals.

Questions about Account-to-account payments
How do account-to-account payments differ from traditional bank transfers?
Traditional bank transfers often require the customer to manually enter a sort code, account number, and reference, which is prone to human error and difficult for merchants to reconcile. Account-to-account payments, facilitated via open banking, automate this process.
The payment details are pre-filled by the merchant's payment service provider, and the customer only needs to authorise the transaction. This ensures that the exact amount is sent with the correct reference, allowing for automated reconciliation and immediate order fulfilment.
What are the primary cost advantages of A2A over card processing?
Card processing involves multiple intermediaries, each taking a fee: the issuer receives interchange, the schemes (Visa/Mastercard) take a fee, and the acquirer adds a margin. For high-risk or high-value merchants, these costs escalate quickly.
A2A payments operate on a flat fee or a significantly lower percentage because they utilise the bank's own clearing systems. By removing three or four layers of fees, merchants can often reduce their total cost of acceptance by 50% or more.
Can A2A payments be used for recurring billing or subscriptions?
Yes, A2A payments can support recurring transactions through mechanisms like Variable Recurring Payments (VRP) or scheduled credit transfers. Unlike card-on-file transactions, which often fail due to card expiry, loss, or theft, A2A links directly to the underlying bank account.
As long as the account remains open and funded, the payment can proceed. This reduces involuntary churn and the need for account updater services that are common in the card industry.
Is the refund process different for A2A transactions compared to cards?
Refunds for A2A payments are typically handled via a credit transfer back to the original bank account. While the initial payment is a 'push' from the customer, the merchant can initiate a reverse transfer through their payment provider's API.
Because the payment provider has the original account details from the inbound transaction, they can automate the return of funds, providing a similar experience to a card refund but without the scheme-specific reversal rules.
How does A2A affect payment abandonment rates at checkout?
Initially, abandonment may be slightly higher if customers are unfamiliar with the flow, but this is offset by the success rates of high-value transactions.
Since A2A uses the bank's own authentication, there is no risk of a 'soft decline' due to 3DS issues or card issuer fraud filters.
For high-ticket items that often trigger card blocks, A2A provides a more reliable path to completion, often resulting in higher overall conversion for specific merchant tiers.
What regulatory frameworks govern account-to-account payments in the UK and EU?
A2A payments are primarily governed by the Second Payment Services Directive (PSD2), which mandated that banks provide Secure Customer Authentication and open up their APIs to third-party providers. In the UK, this is further supported by the Open Banking Standard.
The upcoming PSD3 is expected to further refine these requirements, improving API uptime and standardising the user experience across different financial institutions to ensure more consistent transaction success rates.

A merchant acquirer is a licensed bank that holds your account, takes liability for transactions, and settles funds. The payment processor is the technology layer routing data between the checkout, card networks, and issuing banks. Every card payment requires both components to manage technical encryption and financial liability. They are often separate entities with distinct fee structures.
Read articleA merchant acquirer is a financial institution that processes card transactions and verifies funds. The payment gateway acts as the technological bridge, encrypting sensitive data between the website and the acquirer. Merchants need both components to ensure that electronic payments are accepted, authorised, and settled. Together, they create a seamless and secure payment experience for customers.
Read articleA merchant account is a specialised business account used to accept electronic payments like Apple Pay and Google Pay. It acts as a bridge between the business and the customer bank. Funds are held here for verification and compliance before being transferred to a main bank account. This process ensures that all transactions are secure and reduces the risk of fraud for the merchant and the customer.
