It would be very helpful to be able to show the CIS to be deducted from the Labour element on a Sales Invoice we've issued as the Sub-Contractor giving the customer the actual amount to be paid after everything has been accounted for.

The invoice would need to make all the necessary T21 VAT calculations then show the CIS to be deducted from the labour value at either the standard or higher rate as applicable leaving a balance due to be paid to us the subbie and ideally what value the customer has to pay to HMRC.

We do have a subbie who has been invoicing us from their Xero software which seems to be able to accommodate this issue.
