BoP marketing has often been a challenge, especially when it comes to making the business profitable. Moreover, clean cookstove marketing has been even worse, because customers are not sold on the product until they use it, which cannot happen on the day of purchase. Toyola stoves have overcome this barrier by their innovative “Toyola Money Box”, which is nothing more than a condensed milk tin with a hole on top and a label that reads “Toyola Money Box”. Customers who do not purchase the Toyola stoves on a ten per cent discount right out take on the stoves to use for a month, on the condition that they pay 10 per cent extra. 90 per cent opt for this. They deposit their daily savings on fuel – charcoal, in this box, and at the end of the month, see the benefits of the stove and also have enough to buy the stove. According to Suraj Wahab, founder of Toyola, he has had only one stove returned after a month, of the 100,000 stoves a year manufactured by them. According to him, the company cannot keep up with the demand. Read more here and here.
