Almost every business now runs on software it does not own, delivered under contracts nobody reads. This article explains what those agreements actually say and why the boilerplate is where the money is. It walks through the difference between licensed software and subscribed service, the anatomy of a service level agreement and why uptime credits rarely compensate anyone, and the provisions that decide what happens when a vendor loses your data or raises its price by forty percent. It explains limitation of liability in plain terms, shows why the indemnity everyone negotiates is often the wrong one, and describes the data provisions that determine whether you can ever leave. Worked examples follow a small company through a renewal, an outage, and a breach. The article closes with what to negotiate when you have leverage and what to accept when you do not.
