Hello%0D%0AI am using Acorn account and I am struggling to link it with my quickbooks account.

Hello Sparkle1, 

Welcome to the Community page, 

So if you have a look at this article it tells you all the bank accounts that are and are not available to connect to in quickbooks. If yours does not show it would be a case of csv the transactions into your account so they show up for you to do your books.
