What kinds of roadblock give you guys a headache when making a saas (mvp types, pricing strategies,...)?

Greetings, Im Dee and im From South Africa. Anyone in this group from Africa? Thanks to Admin for accepting my invite. My interest in Saas Stems from taking everything I Didn't want regarding owning a business and it pointed in this direction. I am no coder, hardly tech savvy but that never stopped anyone. Please don't be irritated by any noob questions I might ask as Im still fairly new to this space and definitely not frighted by it especially with all the negative opinions about starting and growing a saas company. Thanks talk to you guys soon! ;)
