The registration of business you mentioned here sounds easy, but not when it has to do with food business. Going through CAC and NAFDAC isn't an easy thing but if you have an insider it is very easy to get it all done.

It is true that large scale businesses are levied more taxes than small scale businesses but sometimes the small businesses pay more than expected through the illegal tax collectors. I've had experiences and so in Nigeria, it is just best to run small businesses online to avoid all the stress.

Choosing a professional when tax related problems arise is the best option. All the best my friend!
