Any input on this question appreciated:

I have a company paying an invoice from a supplier on behalf of a third party company and wish to recover the invoice total only from the third party. All three companies are vat registered and vat is charged on the supplier invoice. Do I claim the input vat on payment of the invoice and must I charge vat when I re-invoice the third party? The third party company is cash strapped, hence the transaction.

Edit: the invoice is vat compliant for invoices > R5000 and is made out to the paying company not the third party company.
