Posting purchases in a company on Flat rate VAT cash based accounting

Hi,

Wondering if anyone can confirm how to post purchases in a company on Flat Rate VAT cash based accounting.

The company I am working for has purchase invoices for Cash & Carry etc as they are an events company, so some items have 20% VAT and others are zero rated.

They also have Fuel and vehicle repairs invoices.

I'm not sure if i should be posting them with VAT.

There are no books that I have seen that tell you how to deal with companies on a Flat rate VAT cash based accounting.

After June the company will be going onto Standard VAT accounts, but it is March through to May that I need to deal with first.

Any help or advice would be much appreciated.

Kind regards

Tracy
