What do you mean by “supply made in the course or furtherance of business”?

“Business” is defined under Section 2(17) include any trade, commerce, manufacture, profession, vocation etc. whether or not undertaken for a pecuniary benefit. Business also includes any activity or transaction which is incidental or ancillary to the aforementioned listed activities. In addition, any activity undertaken by the Central Govt. or a State Govt. or any local authority in which they are engaged as public authority shall also be construed as business. From the above, it may be noted that any activity undertaken included in the definition for furtherance or promoting of a business could constitute a supply under GST law.
