Omni-Payment for Checkout Flex: you have a flexible choice of payment methods

  • Ideal for medium and larger businesses with an annual volume from approximately CHF 200,000

  • Choice of accepted payment methods with individual prices from the acceptance partner

  • Online onboarding and contract applications to acceptance partners directly from the back office tool

  • Single back office tool for managing all online and in-store sales

You must enter a PostFinance business account or a credit card for billing of the one-time set-up fee and other monthly charges for the two modules. Payment and billing are in Swiss francs.

If you are already using one of the Checkout modules, then you meet all the basic preconditions. Whichever module you want to add to your payment solution, you must take account of the following:

  • At least one of our PAX pay terminals is also required for sales in a physical store
  • You have to link your online shop software with our back office for sales in your online store

Further channel-specific requirements and additional links can be found under “Shop system and pay terminals”.

With the Checkout Flex E-Payment and POS payment modules, you decide which acceptance partners you want to work with. You can initiate contracts with the partners you require online directly from our back office tool, allowing you to benefit from attractive conditions. If you’re already a Checkout Flex customer, all you have to do is request a contract update in the back office. Then it’s simply a matter of connecting the pay terminal or online shop software to get started right away.  

You can find detailed information on the individual Checkout Flex modules at the links below.

Shop systems

Our Checkout Flex E-Payment Module supports the most commonly used shop systems in Switzerland. If you want to make sure that your shop system is compatible, you will find an up-to-date list of supported shop systems under “Shop systems” for our E-Payment Module for Checkout Flex. 

Pay terminals

Enable your customers to make cashless payments in your store by signing up for our POS Payment Module for Checkout Flex. You’ll find the right pay terminals for you in our online shop. You need at least one of these state-of-the-art PAX card terminals to enable you to connect it to your POS system and our software.

The hallmark of the Checkout Flex modules is that you conclude individual and flexible contracts with your acceptance partners for the payment methods you want to accept. Prices may therefore differ from the prices shown in the table below.

If you opt for Checkout Flex’s omnichannel solution, the prices of the two modules are added. There are no additional fees for the payment solution.

All prices indicated in the following tables exclude VAT.

One-off fees

The one-time costs may vary depending on whether you’ve already activated a module. You will find a list of possible fees in the table below. Setup of the terminal is free of charge. Hipping costs of CHF 10 per consignment are added.
