woocommerce some questions

Hi

I just made a woocomemrce setup to see what it looks like and compare to opencast for a website that also would like to sell 10 product, not a real ecommerce only

playing around i found that woo commerce doesn’t has:
– shipping cost by weight ( but i found a free plugin, not sure if it works fine )
– geo graphic group, like Europe (Italy, France, Span, etc) found only a pretty expensive plugin
– could not find if it handle invoice

i’m little concern with the fact that it doesn’t handle basic option like shipping by weight
opencart has an commerce look and we need to realize a website that olso can sell 5/10 products

i’m just worried that i could get stuck with tax, invoice, shipping and other options since it is going to sell worldwide
