General principles for goods :

The general principles followed internationally for determining the time of supply of goods are Removal of Goods;

(a) if the goods are to be removed, the time of removal; (b) if the goods are not to be removed, the time when they are made available to the person to whom the goods are supplied. Removal is said to occur when the goods are sent for delivery by the supplier or somebody acting on behalf of the supplier, to a recipient of the supply. (Basic tax point)

Issue of invoice;

Goods are either accompanied by the invoice or the invoice may be sent before or after delivery of the goods. The GST law may provide for time limit within which an invoice has to be issued from the date of supply.

Receipt of payment;

A payment for supply is made either before or after delivery or before or after issue of the invoice.

Normally, the date of removal and the date of invoice could be the same. However, there can be situations where the invoice is issued or payment is received before the basic tax point occurs. Internationally, the time of supply is normally reckoned with the basic tax point or the actual tax point whichever is earlier. Following this principle, the Model GST Law provides to determine the time of supply of goods as the earliest of the events listed above.
