AI Agents & Automation for Small Business

The Small Business Owner’s Real Guide to AI Agents

Depending on which survey you read, somewhere between half and three-quarters of small businesses are already using AI in some form. Most of the advice out there is either breathless hype or vague panic. This book is the middle ground — a practical, no-nonsense guide to what AI agents and automation can realistically do for a small business, and just as importantly, what they can’t.

A shift scheduler that stays out of your way.

Lay out the week, set the shifts, put names on them, and send the whole thing to your staff or print it for the wall. I wrote it in 2013 and took it down when my career took over. It is back, and it is free — no ads, no account, nothing to buy.

About

Darrell Nicholas has spent over a decade in network administration and hands-on field service — including years inside ATM and point-of-sale systems for national companies — before teaching himself iOS, Android, and web development.

Outside of writing, he builds free, ad-free software for the people around him, including a small library of games made for an elderly neighbor, safe from the predatory design most app-store versions run on.
