If you have an early settlement discount applied to the payment terms on your account please ensure the test invoice is including the early settlement discount wording.
Under HMRC guidance, you must show both the Net and VAT values undiscounted on your invoice. When we pay your invoice, we will discount the Net and the VAT accordingly.
Your invoice must also carry the wording:
'A discount of X% of the full price applies if payment is made within Y days of the invoice received date. No credit note will be issued.’
Following payment you must ensure you have only recovered the VAT paid.
Suppliers using the EANCOM EDI format might find it useful to put this wording in the FTX segment in the Header section data element 4440.
Example
FTX+PUR+++(EarlySettlementDiscountWording)' - This FTX segment must go before the RFF segment.
There is a provision in the amended HMRC legislation for suppliers to issue credit notes for every use of early settlement discount. To ensure efficient processing of your invoices, the John Lewis Partnership has chosen only to support the method which does not involve issuing a credit note.
