This is the first question that I grappled with when I started creating this. There are a number of features that I have that I don't believe are available in Companion. Let me first say that I am not very familiar with Companion, but early on I understood that the things I needed were not available in it. Things like inventory management, customer relationship management, and a more complete record of profits and costs, just to get started. I also like to have my own customer data managed by myself and not out in the cloud somewhere, but that's just me. Once I have my own data, I can mine it myself. Some of the many features I have built in have been in response to specific needs. Other features include customer lists, forms, delivery worksheets, revenue log and a business summary and others. I'm sure what I have is not for everyone, but I can share it.
