Online store requirements

To activate our payment system for your online store, the following requirements must be met:

• You must have a PostFinance business account or a credit card for billing of fees 
• The online payments can also be used for sales and outpayments in foreign currencies, depending on the acceptance partner

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

The “Payment Service Providing” contract for Checkout Flex can be concluded online in just a few minutes. After our check, Checkout Flex will be activated within five working days.

You can decide for yourself which payment methods you would like to offer. You will need to conclude a separate contract with each of the providers (acceptance partners). PostFinance takes care of sending the contract request for you directly from the back office tool in the Checkout Flex setup process.

Please note: It may currently take several weeks to conclude contracts with Worldline and Concardis. PostFinance has no influence over this period.

Personalizing e-mails and documents

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

Simple accounting

The sales reports (reconciliations) from the various acceptance partners are consolidated and clearly displayed in the Checkout back office tool. The sales receipts are automatically archived online. You can export them via CSV and import them into your accounting software.

Fraud management

We support you in protecting yourself against fraudulent activities online. We offer the following measures to help you exclude and reject invalid payment methods before a transaction can be made.

• You can use various filter options (card category, card type, etc.) to exclude certain payment methods
• You can set up fraud screening for the card issuer, the BIN, the country, the address and the IP address
• You can block cards and payments from certain countries

Connected services − connecting Checkout to SaaS shop systems

If you use a shop system as an SaaS (software as a service) solution, you can connect our payment system directly using the integrated connected services. Contact your SaaS provider directly about connection to the shop system.

All fees indicated in the following tables exclude VAT.

These fees are charged directly by the acceptance partner for the relevant payment method. Please check the relevant acceptance contract to find out more about the conditions.
