Hello there, @BeerOutside.
I can share some information about merging accounts in QuickBooks Online (QBO).
QuickBooks allows you to merge two accounts. However, there are some accounts that can't be merged, like bank accounts connected to online banking. Thus, it's the possible reason why you're getting the error.
You can disconnect the other account from online banking to merge the accounts. Here's how:
- Click Banking from the left menu.
- Choose the bank account you want to disconnect.
- Select the pencil icon and click Edit account info.
- Click the Disconnect this account on save field.
- Select Save and Close.
