I don't have serious hard numbers before that, as the CRM saw its first commit around sale #6.
My wife has a small business similar to yours, and I ended up building a micro CRM for her, complete with scraping (some of our vendors don't offer an Api), reports, invoicing etc.
Absolutely agree with this, I've come to realize I was addicted to the feed. It took, and still does, a significant effort to control the effect (mostly by regulating access on a scheduled basis).
