I have a client who runs 2 separate companies, one is VAT registered and the other isn't. He receives a couple of supplier invoices that relate to both companies, i.e. the premises rent invoice needs to be split between the 2 companies, his phone invoice, insurance etc. what is the correct way to deal with this?
I have got myself in a muddle with this and my brain will not see a clear way to sort the issue, so that the correct amount shows in each company.
