Hello, i was living in Ghana 5 years and had my business running. I was fixing computers, installing security systems, cameras, intercom and doing phone repairs. The business did not move at all. in the 5 years there has been no increase in contracts or sales so i decided to stop.
You have to be careful when investing in this country. You will be happy if you are not running loss.
People who make money here are usually criminals, scammers, thiefs and people who have connections to high ranking officials. The rest will be poor. The average small local shop has a turnover of 500 to 800 dollar a month which is absolutely nothing. The economy is very weak which result in people cannot pay for your services and you always need to reduce your prices so you can at least make some sales and cover your expenses.
I would love to live in Ghana but if you are not getting money from outside it will be hard to survive.
You also need to know, the money you invest in the beginning will determine your living standard. There is no starting small and growing big. Starting small means you always stay small. Starting big means you almost always remain big. Business does not really grow or expand here. Its fixed according to what money you bring from outside.
