Is there a way to post deductions on livestock sales invoices so that the input vat on the deductions does not appear as negative output vat in box 1?

Hi there, danielle-campbel.

You can create an item under an expense account and add it as another line on an invoice. Also, make sure to enter the item as negative on the invoice to track it as a deduction. 
Though, it’d still be best to get in touch with HMRC for proper guidance on recording this transaction.
