HI I have a client who has applied for VAT registration from the 1st of October, it is under review at HMRC but we need to start invoicing on Sage with VAT (CIS and reverse charge scheme) is this possible without a VAT number and can my client start putting in the purchase invoices with the VAT split as well, without the VAT registration part filled in on Sage (online sage) and if this is possible how is it done?
