If you need to make adjustments to an existing sales invoice, you will need to issue a Credit Note. This can be done directly on your Outmin dashboard.
How it works
To issue a Credit Note, you'll need the same information required to issue an invoice: a customer, the currency you wish to issue the credit note in, and which of your products the credit note relates to. The Credit Note will follow the numbering convention of your invoicing.
Once you're logged in your Outmin dashboard, go to the "Sales Invoicing" tab and click on "Invoices"
Click on Create Credit Note
Input the same details as the invoice you're looking to amend
Select the customer and currency in the drop-down menus
Select the Product/Service from the dropdown, click on the + Add button to add multiple products/services if needed
