Understanding Letters of Intent

At many points in your entrepreneurial journey (whether you’re forming partnerships, acquiring assets, or setting up collaborations) you may hear the term Letter of Intent.

A letter of intent in business is a document outlining the preliminary understanding between parties before finalizing a formal agreement. Companies often use LOIs to announce new transactions or relationships before executing definitive contracts, such as purchase agreements.
