Adding credit notes to invoices (upload as a negative invoice)

Credit notes on Dwellant must be processed as a separate invoice to the original. Additional documents would be for evidencing additional charges incurred beyond an agreed-upon fee for example.
 
In order to upload a credit note, you need to follow the exact same process as you have for the invoice, but when inputting the values and figures, you need to make them negative, so a credit note for £100 must be uploaded to Dwellant as an invoice for -£100.
 
Once this is sent off to the customer, they will need to associate it to the correct works and process it separately.
