An invoice can be reversed or deleted to undo everything created when the invoice was saved. This returns products to inventory, restores the account balance to its previous amount, and removes the invoice entry from the Sales Summary by Date report.
Note: Inventory totals will not be adjusted if the original invoice was entered as a historical invoice.
Locations:
Contact Profile
From the Contacts list, search for and open the contact profile where the invoice was originally created (if the contact profile has been permanently deleted from Boulevard's Recycle Bin, follow the steps under Option 2). In the contact profile's
Account & Invoices tab, check the box next to the invoice you want to delete. Then, select the delete button
on the Invoices section header and select Yes to confirm the deletion.
Invoice Log
From the sidebar navigation, click 
Business Tools, then Invoice Log.
If necessary, use the Advanced Search or filter button 
to locate the invoice to be deleted. Select the checkbox next to the applicable invoice. Select the delete button then choose Yes to confirm the deletion.
