Account-to-Account Payment
An account-to-account payment moves money directly from the payer's bank account to the payee's, without a card network in between — a transfer initiated by the payer, a direct-debit mandate, or, under open banking, a licensed third party at the checkout. It settles over domestic rails, instant where they exist, costs cents rather than a percentage, and is the alternative to cards the industry has built since PSD2.
- Also known as
- A2A payment, Pay by bank, Bank transfer payment
- Used at
- bill payment, peer-to-peer transfers, e-commerce checkout in markets with instant rails (the Netherlands' iDEAL, Poland's BLIK, India's UPI, Brazil's Pix, the UK's open-banking payments), B2B settlement, account funding at fintechs
- Binding
- the payment-system rules (SEPA, Faster Payments, UPI's NPCI rules), open-banking regulation (PSD2 payment initiation, the UK's standards), and consumer-protection rules that differ from cards' — no chargeback right on most transfers
- Typical cost
- a few cents per payment to the merchant; no interchange; the open-banking initiator's fee is 0.1–0.5% or a flat amount, against 1–3% for cards
- Typical adoption
- dominant in markets with instant rails and a national scheme (Pix at over 40% of Brazilian transactions by 2024; UPI at over 15 billion transactions a month in India); growing but small in card-dominant markets, where the consumer's protection and habit favour cards
- Parties
- the payer and their bank, the payee and theirs, the payment-initiation provider if any, the scheme operator, and the regulators of each
How an account-to-account payment works in practice
At a checkout the customer chooses "pay by bank". A licensed payment-initiation provider, through the customer's bank's open-banking API, presents the payment — amount, payee, reference — and the customer approves it in her banking app with a fingerprint. The bank sends an instant transfer over the domestic scheme; the merchant's account is credited in seconds; the provider confirms to the checkout. No card number was entered, no interchange was paid, and the payment is irrevocable — the merchant has its money and the customer has no chargeback to raise if the goods do not arrive, which is the model's strength and its weakness in one.
Where it wins, it wins on cost and on instant settlement: merchants with thin margins and high tickets, bill payers, marketplaces paying out, fintechs funding accounts. Where it lags, it lags on habit and protection: a card is one tap and carries a dispute right; a bank transfer is an app switch and carries none, which regulators in some markets are moving to change. The national schemes that made A2A dominant — Pix, UPI, iDEAL, BLIK — were built with a brand, a QR standard and near-universal bank participation, which open banking in Europe and the US has not yet assembled.
For payments M&A the A2A providers — initiation platforms, pay-by-bank checkout companies, the fintechs behind national schemes — are the acquisition targets of card companies hedging their own model: Visa–Tink, Mastercard–Finicity and Aiia.
Example
A UK furniture retailer with a €600 average ticket pays 1.3% on cards — €7.80 per sale. It adds pay-by-bank through an open-banking provider at €0.25 per payment. In a year 18% of customers choose it, drawn by a €10 discount the retailer funds from the saving: 9,000 payments, €67,000 of card fees avoided, €2,250 paid to the provider, €90,000 of discounts. Net: a small loss on the incentive, offset by instant settlement that took three days of receivables off the balance sheet — and a decline rate on those payments of 2% against 9% on cards. The retailer's finance director keeps the discount at €5 in year two and the share holds at 15%.
Common mistakes
- Offering pay-by-bank with no incentive in a card-habituated market and expecting adoption. - Forgetting the consumer's loss of the chargeback right, and the trust it costs on high-ticket goods. - Building on open-banking APIs with bank-by-bank reliability and no fallback to cards. - Treating an irrevocable transfer as final when the sending bank can still recall a mistaken one under scheme rules. - Comparing A2A's cost per payment with cards' and ignoring the conversion difference.
