Let's say you've got a revenue account in QuickBooks Online for all of you services (even revenue from services outside of Goodshuffle Pro).
As you may know, when you integrate with QuickBooks Online a few accounts are created in your account (Product Rentals, Product Purchases, Services, etc).
You probably want your Goodshuffle Pro Service income to feed into your main Services account.
To set this up, head to your Chart of Accounts in QuickBooks Online.
Next, select the Account that was created from Goodshuffle Pro and click 'Edit'
Then, mark this account as a Sub-Account and specify where it should feed into.
Finally, click Save and Close.
Now your Services from Goodshuffle Pro will populate your 'parent' Services Account in QuickBooks Online.
