Wrong Income/Expense Account Assignment

The option to reclassify the income or expense account for an item is to manually change it one at a time, charley-b.

You'll want to make sure past transactions are also updated. To do so, please follow these steps:

1. Go to Settings ⚙ and select Products and Services.
2. Under the Action column of the appropriate item, select Edit.
3. From the Income account ▼ drop-down, choose a different account.
4. Select Save and close.
5. Under the Action column of the same item, select Edit.
6. From the Income Account ▼ drop-down, choose the correct account.
7. Select the Also update this account in historical transactions checkbox.
8. Click Save and close.
   
   

If the account won't show up from the list, you can check if the detail type is correct. Here's how:

1. Go to Settings ⚙ and select Chart of Accounts.
2. From the Action drop-down of the account, select Edit.
3. Change the detail type to Sales of Product Income if necessary.
4. Click Save and close.
