Catering reviews

As if VAT isn’t complicated enough already for public sector organisations, there may also be a mixture of VAT liabilities being supplied in one of your catering outlets or coffee shops.  How do you manage VAT liability in this area?  Have you introduced electronic tills or are you relying on old percentages to calculate the proportion of zero-rated supplies?  Could there be an opportunity for the organisation to reclaim some additional VAT?  Worth a chat at least, with someone who can help.
