CIS INVOICING, How do i issue a partial refund?
I issued a client an invoice for £10k total. I deducted the 20% CIS so invoice is for 10k minus 2k CIS. The client paid 8k.
I now have to issue a partial refund. When i send funds back to them do i credit note the amount less CIS @ 20%? And then i transfer this amount (credit not less CIS)?
