If you have an invoice item you don’t want to keep in your ‘Products and services’ list, you can add it as a one-off in the Mettle app.
Go to the ‘Invoices’ tab and select ‘Create invoice’.
Select ‘Add item’ and fill in the details.
Untick the ‘Save item’ box.
Fill in the rest of your invoice and send it to your customer.
Note: Unticking this box stops the item from being saved to your permanent ‘Products and services’ list.
