Hello Breanice starting a Mpesa business is a great idea If you had shared your location we could have estimated the rent . But let's estimate rent at 1500 . Before you start an mpesa have an ID for registration of your mpesa agent line. Secondly you need certificate of good conduct so you need a KRA pin for the same. To open a Mpesa business you need a minimum of 20,000/= It will be breaked down as follows. 5000/= to buy an mpesa line . 15,000/= as the starting float this is the amount for withdrawals.

For a mpesa business to run well it needs to be at a busy place such as a business centre.
You can locate your mpesa near a shop or a wholesale . You can as well talk to a shop owner or a hardware owner locate your shop next to it , this is because many people like transacting before buying at shops or other business places .

You can as well add selling of safaricom lines which go at 50 at retail and sell them at 100. As well register as a bingwa sokoni agent and be getting the commission for the same . You can add selling of of phone covers and screen protectors to make use of the space. Sell also snacks At last be your own security.
Never show your details to anyone else. Below are samples of mpesa shops you can have one depending where you will locate it.. Hope you have a successful business.
