If you have companies under multiple Intuit IDs, you may want to add them under the same ChronoBooks user to copy between them or to keep a single subscription.
Start by logging in with the Intuit ID that you have previously used for ChronoBooks.
Next, visit the Companies page and click the green "Add a Company"/"Connect to QuickBooks" button.
On the window that pops up, click the "Not you?" link in the upper-right. This allows you to change Intuit IDs without logging out of ChronoBooks.
Now log in with the Intuit ID associated with the company you'd like to add. Select the company or firm you'd like to add.
