By a traditional custom, the Nattukottai Chettis live largely by money-lending. They never serve under any one outside their own community. They either trade on their own account, or are employed as agents or assistants. The pay of an assistant is always calculated for a period of three years, and a portion thereof is paid in advance after a month's service. This the assistant invests to the best advantage. At the end of a year, a portion of the balance of the pay is handed over to him, leaving a small sum to be paid at the end of the contract period. His expenses for board and lodging are met by his employer, and he may receive a small share of the profits of the business. A man, on receiving an agency, starts on an auspicious day, and proceeds to a temple of Ganesa, and to a matam (religious institution) containing figures of Ganesa and Natesa. After prostrating himself before the gods, he proceeds on his way. If he encounters an object of evil omen, he will not continue, and, if he has to journey to a distant spot, he will throw up his appointment. The accounts of the Nattukottai Chettis are audited triennially, an annual audit being inconvenient, as their business is carried on at various remote spots. The foreign business is said [111] to "be transacted by agents belonging to the caste, who receive a salary proportioned to the distance of the place, and also, usually, a percentage on the profits. They generally serve for three years, and then return, and give an account of their stewardship." The commencement of a fresh period of three years is made on an auspicious day called puthukanakkunal (fresh account day), which is observed as a holiday. No business is transacted, and customers are invited, and receive presents of fruits, sweets, etc.
