Hi I can't connect to zettle reader 2 please can you help me

Hello Przemekwegner-bt, 

Welcome to the Community page, 

With Quickbooks Self-Employed you can not connect to any third party apps that is why you cant connect to your zettle reader 2 account. You can only Connect bank accounts up in the Self-Employed version of Quickbooks. Only in our Quickbooks small business online accounts you are able to connect to 3rd party apps and bank accounts.
