14-800 Introduction to single (composite) and multiple supplies
VAT is a tax on transactions and is therefore relatively straightforward to apply when a single price is paid for a single and identifiable supply.
Many transactions involve a single price being paid for a package of items. This can involve goods, services, or even a mixture of both goods and services. There are various ways of deciding the treatment of such a transaction but, in the first instance, it is crucial to decide whether it is either a single or a multiple supply.
A ‘composite supply’ is a single supply with more than one component or element.
