Banking
The transferral of money, loans and guaranties are essential to al types of buisness development, whether you talk micro economy or big buisness.
Thats why I think it is such a shame that it has turned out to be Western Union who are the fastest and most reliable company when it comes to transfering money, at least on a small scale, not that I am unhappy with their service at all, but I find that when a country has a fragile economy, every possible income counts. And I would prefer to pay the transaction fee to a locally based bank, not a multi national company. However, if you are looking for banks in Burundi, here are the information about a few of them.
