The transition from PostFinance PSP to Checkout Flex
In the constantly changing digital world, companies' offerings also adapt to the latest technology trends. As part of these dynamic developments, PostFinance has decided to phase out the PSP products Basic, Startup, and Professional by the end of the year. However, this does not mark the end, but rather the beginning of a new era of payment processing: PostFinance Checkout Flex.
