How to move business online?

Hello everybody! I see that here is the frequently asked question "How to transfer your business from offline to online?"
So, my story, maybe someone will be useful 
I started my home business about 2 years ago. My specialization is consulting. Just a couple of months ago, I found the perfect solution for running my business - ExpertBox software. https://expertbox.io/ The software was very helpful in organizing my work. Clients book a place in it for a consultation with me at the hours at which I indicated. There is also a video/audio solution and billing directly in it. This is very convenient for me!
