Ask HN: B2B or B2C - Which way to go?

I am experienced in developing and implementing enterprise packages (like ERP, CRM). I want to start a start-up in this domain, selling to small companies. I want to experiment something part time first before I quit my job and do start on my own.

I can take a) the B2B route - Do I need to pick up sales skills in my current job and develop contacts in my local market before I jump full time. I plan to enter an existing market/product. The challenge will be my lack of sales experience?

b) the B2C route - I might not have to do any institutional selling and concentrate on my product better. Here, the product/market fit is untested. Not sure which path to take. Experiences/ advice needed.
