A trade that waits for the season
Implements and gud both sell to a calendar. A dealer asks for a rim and dhura rate weeks before he needs stock, and then says nothing until the season turns. The temptation for a Baraut unit is to fill that silence with reminders. On WhatsApp, a reminder to a dealer who has not ordered is a marketing message, and it needs his agreement first.
The better habit is to ask at the right moment. When the dealer orders, or when he pays, he is already in the thread. That is the time to ask whether he would like next season's price list, and to keep his yes on record. After that, the list can go as a marketing template; until then, the unit replies when he writes.
