Yes, if the invoice has information confirming that the parties agreed to the delivery of a specified type and amount of goods of a certain value for a lawful consideration,
Section 10 of the Contract Act, 1872 (“Contract Act”) provides as follows:
“All agreements are contracts if they are made by the free consent of parties competent to contract, for a lawful consideration and with a lawful object, and are not hereby expressly declared to be void.”
It is also pertinent to refer to the applicable provision under the Sale of Goods Act, 1930. Section 5(2) of this law provides in relevant part as follows:
“A contract of sale may be made in writing or by word of mouth, or partly in writing and party by word of mouth or may be implied from the conduct of the parties.”
In view of the above provision, there is no mandatory legal requirement of a formal written contract for the sale of goods and even an oral agreement that meets all the legal requirements of a contract can be considered a valid contract.
