I noticed that some of my paid invoices at the beginning of the year used services that were coded as "Sales" instead of "Professional Services". Can I correct that?

I got you on this, td16.

Yes, we can easily correct your previous transactions in QuickBooks Online. We have an option where you can update the old transactions when changing the item's Income account. Here's how to do it:

1. Click Sales on the left menu and go to the Products and Services tab.
2. Look for the service item you want to update and click Edit.
3. If you already set the correct Income account, toggle it to a different account.
   Then, select again the correct income account.
4. Mark the Also update this account in historical transactions box.
   This option will appear after toggling the affected income account.
5. Click Save and close.

These steps will work for Service and Non-inventory types.

If you updated the income account of an inventory item and wanted to affect your historical transactions, you'll have to toggle the items on the transactions itself.

We'll be right here if you need further assistance in managing your sales items. Have a great day!
