If I accidently put an expense as a sales receipt, how can I change it to an expense?

We can delete and recreate it into an expense, useratgcustom.

We're unable to change transaction types. We can take note of the details you entered in the sales receipt and then create an expense to record it. 

Here's how to enter an expense:

1. From the left menu, click the + New button.
2. Select Expense.
3. Enter the vendor information and other important details.
4. Click Save and close.

To delete the sales receipt, you can follow these steps:

1. Go to the Sales menu and select Customer.
2. Look for the customer you associated with the sales receipt. 
3. Go to Transactions List and open the sales receipt.
4. At the bottom, click More > Delete.
5. Select Yes to confirm if prompted.

All activities you've done in your account are tracked and can be seen in the Audit Log report. You can see who made changes to your books and what they did.

If you have other questions, feel free to post them here. Take care and have a good one!
