late payment of vat

Hi

I have been working for a company who have refused to pay the vat element of our invoices until we received our vat number even though they were invoiced correctly for the total amount with the vat not shown separatly and the invoice clearly marked "VAT registration applied for" Two months after receiving and advising them of the VAT number they have still not paid the outstanding VAT. Can I charge interest? On individual invoices or just the total?

Can I charge interest? From the date of the invoice or from the date they were advised of the vat number?

Hmmm. That is quite a tricky one!

I'm not sure anyone could give you a definitive answer, however our thinking is that you would treat this like any other part paid invoice and calculate the costs and interest on that basis.
