I’m trying to integrate two separate square accounts but cannot figure out how to add more than one. Does anyone know how to do that? Thanks in advance.

You can use a 3rd party connector to reconcile multi Square accounts into QBO.

Hi dmitro-jdosteopa,

Currently, Square can only sync with one QuickBooks Online account.  For more details on how to sync Square accounts, you can check this article: Sync Square with QuickBooks Online. 

Feel free to place a comment if you have other questions.  We would be glad to help!
