I'm using the app to send invoices from shopify to factuursturen and it works flawless. No remarks and responses from support are very quick.

The application looks like it is made before the 2000's and it behaves like it is this old. I was trying to get it intergrated with "Rompslomp" and after invalid licence keys lots of emails with their support it was supposed to work. So i go and check why the orders are not processed in rompslomp and this application shows "Invalid authentication". You are better off spending your time to manually put the orders in your accounting software then using this application. Update: Na hulp van Joost werkt de koppeling nu goed. Het is wat lastig instellen vooral als het met licentiesleutels misgaat. Maar als het eenmaal werkt dan is het wel erg makkelijk
