Consequential damage exposure
A website goes down due to a bug in code you wrote. The client claims $300K in lost e-commerce revenue. Your project fee was $15K. Without a consequential damages exclusion, that $300K claim is legally viable.
Unlimited direct damages
Even without consequential damages, "direct damages" can include the cost to hire someone else to redo the work at current market rates — which may significantly exceed the original contract price.
Legal costs alone are devastating
Even winning a lawsuit you could have prevented with a liability cap costs $50,000–200,000 in legal fees. The cap isn't just about the judgment — it's about making the economics of litigation unattractive to the client.
Insurance doesn't cover everything
Professional liability insurance has exclusions, deductibles, and policy limits. A limitation of liability clause is the first line of defense — insurance is the second.
