Question

I've 4 entities on Quickbooks and I used them all at the same time for company operations and transactions, and it's not possible to open different entities in tabs.

Original commenter did not share additional details

You need to utilize the private/incognito browser to do so.

QBO account 1 = Chrome - primary

QBO account 2 = Chrome - incognito

QBO account 3 = Edge - primary

QBO account 4 = Edge - private

You can use other browsers if required.
