I was walking down the road and the woman that fries Akara(bean cake) had company in person of the woman that sells bread. As i made my way back, i stopped by at her store to get some fries and i found the bread seller helping her out, for some reason, i changed my mind from fried yam to Akara and bread and bought from both of them.

My aunt owns a restaurant and recently a young man located his viewing center close to her store. She records more sales when there's a football match as some customers from the other end might like to eat and drink, so also the young guy, someone might want to relax after a heavy duty meal.

A few months back, i was scouting for a studio location with a friend and i adviced him to pay for the most expensive option simply because it was in between a make up studio and a salon. Most of his earlier customers were ladies who came for a face beat or hairdo just decided to have a clear picture of it.

I could go on with stories of how businesses succeed just by complementing each other

what does it mean to complement?

To complement simply means to complete or fill in totality.
The business of complements simply allows you to complete the service or product a particular company offers.

There's is more value and success when businesses come together in separate but related products or service to satisfy a customer.

If you are looking for a business to do, look around you, there's a business you can run complementary product and service with and you'll be successful

It doesn't necessarily have to be about competition. The business of complements can save the day
