One of our first businesses was a sari sari store. We rented a space in town for 1,500 pesos a month. Instead of a window we spent 15,000 php and added a door so people could walk in. The total floor area was 20sqm which is not a large area. Everyone told us it would fail as other people had tried before. When we sold it after 6 years it was making a profit of around 25 to 30k a month. Hard work at the time but it paved the way for better things.
