One-sided agreements that heavily favor one party should include limitations of liability to protect against costly damages claims. Effective contracts require affirmative consent, such as with clickwrap that forces the user to click "I Accept" after viewing terms. Letters of intent can be legally binding, so they should be taken seriously and drafted by a lawyer to outline key deal points like payment amounts, intellectual property issues, and liability. Requests for proposals are used to solicit offers from vendors to provide a specified service within the client's budget. Standard agreement templates should be prepared ahead of time to efficiently finalize deals when opportunities arise. Limitations of liability are a standard part of most contracts.
