Hi @publishingsoft,

I'm here to share some insights and clear things up regarding parent and sub-accounts for credit cards.

QuickBooks Online (QBO) acts a bit different compared to QuickBooks Desktop. You can either connect the parent credit card, which will pull up all transactions including its sub-accounts. Your other option is to add all sub accounts to your QBO company, leaving out the parent account. To connect both the parent and its sub-account(s) will result in an error message that was mentioned above.

With that said, this isn't a bug in the system. I understand where you're coming from and I can see the feature you mentioned to be very helpful for all users with connected online credit card accounts.  I appreciate that you have pointed this out, and we have taken note of it.

Further details on how you can set up credit card sub-accounts in QBO are in this article: About bank or credit card sub account setup. This will guide you om how best to proceed with connecting your online credit card accounts, with respect to how you're individual bank sends the downloaded transactions.

If you have other questions, leave them below and I'll get back to you as soon as I can.
