Online contract conclusion and communication of the request to the acceptance partners

The Payment Service Providing contract for Checkout Flex can be completed online in a few minutes. After our check, PostFinance Checkout Flex will be activated within 10 working days.

To activate the payment methods, you need a separate contract with the respective acceptance partner for each payment method. PostFinance automatically arranges the contract request for you in Checkout Flex Onboarding. The amount of time it takes to activate the payment method depends on the respective acceptance partner and cannot be influenced by PostFinance.
NB: Currently, the conclusion of contracts with SIX and Concardis may take up to several more weeks.

Paying with stored cards

With this feature, as a retailer you have the option of debiting recurring amounts (such as for subscriptions) to the cards previously stored by the shopper.

Payment link and charge flow

• You can use the payment link to process transactions easily by sending the shopper a payment link via e-mail. The shopper clicks the link and settles the outstanding amount with one of the payment methods connected to the shop.
• You can use the charge flow feature to automate processes for debits via e-mail.

Personalization

In the Checkout back office tool, you can personalize e-mails to the shopper (such as payment statuses) or documents (such as payment confirmations or credits).

Accounting

The revenue reports (reconciliations) of the various acceptance partners are displayed in consolidated form in the Checkout back office tool, can be exported via CSV and imported into your accounting software.

Fraud management

• Fraud checking for the card issuer BIN (Bank Identification Number), country, address and IP address
• Blocking cards in selected countries
• Filtering card categories. The filter is applied to the first 6 digits of the card that identify the issuer (based on the BIN range) and the card category
• Filtering by card type controls whether filtering of the card type derived from the BIN range is active

Keep an overview

All transactions can be managed directly in the shop system. The back office tool also gives you access to details of the payment transactions, and you can manage your users and settings at all times. You also have the option of authorizing a partner (an agency, for example) to implement technical configurations.

Advanced users can also customize the automatically preconfigured services and, if required, set up another shop (space) without additional costs.
