So I am starting a company with my stepdad and I am going to be incorporating technology into it. My grandfather didn't have technology and was telling me about how everything was handwritten and mailed out, and how he had a hard copy of everything. I plan to still have a hard copy of everything just in case something happens, but I really want to use different programs to keep track of everything, do invoicing, and even possibly advertise. My question is, how many of you use the internet to your advantage and how do you protect your business online? I assume it should be more than what I have on my personal computer (antivirus and firewall), but I don't know what else I would need. Thanks!
