Most small businesses do not have a tool shortage. They have eleven subscriptions, four of them forgotten, two of them doing the same job, and no clear answer to what would break if any of them were cancelled tomorrow. The problem is rarely finding a tool. It is deciding between them and then living with the decision.

This category covers tool selection, stack design, and the decisions that surround them. The articles here treat buying software as an operational choice rather than a shopping exercise, which means they spend more time on evaluation criteria, switching costs, and what happens in month six than on feature comparisons that go stale in a quarter.

Topics include how to evaluate an AI tool before committing, free versus paid tiers and where the line actually sits, off-the-shelf products versus custom builds, auditing a stack you inherited, switching tools without losing the work already built on the old one, and the difference between an AI agent, an automation, and a chatbot when a vendor calls all three the same thing.

The aim is a small stack you understand completely, rather than a large one you are quietly afraid to change.
