The overview
Sofort, currently integrated into the Klarna ecosystem, operates as a real-time bank transfer overlay service primarily serving the DACH region. Unlike traditional credit card processing, Sofort facilitates a direct communication channel between a merchant and a customer's online banking portal.
The system uses the customer's existing banking credentials to initiate a push payment, which eliminates the need for manual data entry of card details or account numbers.
By acting as a third-party initiator, the service provides the merchant with a real-time confirmation of the transaction, though the actual settlement of funds often occurs via the SEPA Credit Transfer framework over subsequent business days.
This method sits within the Alternative Payment Method (APM) layer of the stack, offering a secure alternative to cards by utilising the bank's own multi-factor authentication protocols. It is a critical component for businesses targeting European markets where bank-based payments are preferred over revolving credit.
How it works
Payment Method Selection
The customer selects Sofort at the checkout stage. The payment gateway redirects the user to the secure Sofort interface, where they choose their resident country and the specific financial institution holding their account.
This step ensures the transaction is routed through the correct national banking infrastructure for processing.
Bank Account Authorisation
The customer enters their online banking credentials within the secure Sofort overlay. This environment is separate from the merchant's site, ensuring that sensitive login information is never shared with the seller.
Sofort establishes a temporary, encrypted connection to the bank to verify account access and available balance.
Transaction Confirmation via TAN
To authorise the transfer, the customer provides a Transaction Authentication Number (TAN), which is typically delivered via SMS or a dedicated banking app. This process satisfies Strong Customer Authentication (SCA) requirements under PSD2, providing a high level of security against unauthorised access and fraudulent transfers.
Real Time Status Feedback
Once the bank authorises the transfer, Sofort returns a real-time notification to the merchant.
This confirmation allows the merchant to update the order status and proceed with fulfilment immediately, even though the physical settlement of funds to the acquirer may take one to three business days.
Why it matters
Market Penetration in DACH
In territories such as Germany and Austria, bank transfers remain a dominant preference for digital commerce. Relying exclusively on card schemes like Visa or Mastercard can lead to significant cart abandonment.
Integrating a bank-direct method ensures that merchants can capture a wider demographic of consumers who do not possess a credit card or who prioritise the perceived security of their own banking environment.
Reduced Cost and Risk
Sofort transactions generally carry lower processing fees compared to standard interchange-plus card models. Because the customer initiates the payment through their bank, the mechanism for traditional chargebacks does not exist in the same way it does for card payments.
This reduces the merchant's exposure to friendly fraud and the administrative overhead associated with managing disputes and retrievals.
Use cases
DACH Region E-commerce
Online retailers targeting German-speaking markets use Sofort to provide a localised checkout experience, catering to the high percentage of consumers preferring bank transfers over credit cards.
High Value Transactions
Travel agencies or electronics vendors facilitate larger payments where credit card limits might be restrictive, utilising the customer's liquid bank balance for immediate authorisation.
Subscription Initialisation
Service providers use Sofort for the initial payment in a sequence, verifying the customer's bank account before transitioning to other recurring payment instruments for subsequent billing cycles.
Cross Border Trade
Merchants based outside of Central Europe utilise Sofort through a PSP to accept payments from international customers without needing to establish local entity bank accounts in each country.
By the numbers
This represents a typical range for bank-transfer preference in German-speaking markets, where Sofort is a primary method alongside GIROPAY and SEPA.
Industry data suggests bank transfers have significantly lower dispute rates compared to cards, as the push-payment nature limits typical chargeback rights.
Merchants often observe this range of improvement in conversion when adding native banking options for users who lack saved card details on mobile devices.

Questions about Sofort payments
How does Sofort handle chargebacks and disputes compared to credit cards?
Sofort operates as a bank transfer, which is a push payment. Unlike credit cards, there is no built-in chargeback mechanism that allows a customer to reverse a transaction through their bank once it has been authorised.
While a customer might attempt a retrieval through their bank, the merchant is not subject to the same automated dispute process found in card scheme rules. Any refunds must typically be initiated by the merchant as a separate credit transfer back to the customer's account.
What is the typical settlement timeframe for Sofort transactions?
While the merchant receives an instant confirmation that the payment has been initiated and authorised, the funds are not immediately available. The money moves via the SEPA network, which generally takes between one and three business days to arrive in the merchant's account.
The exact timing depends on the banking cycles of both the sending and receiving institutions, as well as the processing times of the involved payment service provider.
Is Sofort compliant with Strong Customer Authentication (SCA) under PSD2?
Yes, Sofort is inherently compliant with SCA. Because the payment process requires the customer to log into their bank's own environment and provide a second factor of authentication, such as a TAN or biometric approval via a mobile app, it meets the multi-factor requirements.
The merchant does not need to implement additional 3DS layers for Sofort transactions, as the banking portal handles the authentication natively during the transfer initiation.
Which countries are currently supported by the Sofort payment network?
Sofort is most prominent in Germany and Austria, where it has the highest market share. However, the network also supports transactions in Switzerland, Belgium, the Netherlands, Italy, Spain, and Poland.
The availability of the service depends on the merchant's acquirer and the specific banking integrations maintained by Klarna in each respective territory. Merchants should verify regional support based on their specific MID and target customer base.
Does the customer need to create a Sofort or Klarna account to pay?
No, one of the primary advantages of Sofort is that it does not require a separate wallet or account registration. The customer uses their existing online banking credentials (PIN and TAN) provided by their financial institution.
This lack of registration reduces friction at checkout, as the user only needs to have an active online banking account with a participating bank to complete the purchase.
What are the common decline reasons for a Sofort payment?
The most frequent reason for a Sofort decline is insufficient funds in the customer's bank account at the moment of the transfer.
Other reasons include incorrect entry of banking credentials or TANs, the bank's internal fraud prevention filters blocking the transfer, or technical timeouts between the Sofort interface and the bank's API.
Unlike hard declines on credit cards, these are often temporary issues that the customer can rectify by trying again or using a different account.
How does Sofort integration impact the merchant's PCI-DSS scope?
Since Sofort is a bank transfer method and does not involve the handling of primary account numbers (PANs) or other sensitive cardholder data, it typically sits outside the strictest sections of PCI-DSS compliance. The merchant never sees or stores the customer's banking credentials.
However, the merchant must still maintain general security standards for their checkout environment and handle transaction data according to local data protection laws such as GDPR.
