From August 2018 Swish is available as an internal payment option (alternative to PayPal) in Zynatic. We should set it up so that we an use it as it is more common than PayPal in Sweden.
Setting it up requires following the instructions at Konfig → Swish integration (more detailed instructions) and getting the required Swish certificates.
We might have to update our Swish number in Zynatic since its currently entered with spaces to be easily readable on e.g. invoices. If so we might follow up with a request to Zynatic that the numbers be displayed with spaces (as per how Swish does it).
Ones this is up and running we need to revise our Invoice message to mention that Swish and PayPal are both available if you log in.
