The Difference Between an LOI and an Offer to Purchase

Why the distinction matters
Although both documents outline terms, they serve different purposes and carry different levels of commitment. Understanding the difference helps you avoid confusion, manage expectations, and move through the transaction with clarity.
What a Letter of Intent (LOI) is
An LOI is typically the first formal step in the buying process. It outlines the major terms of the deal but is usually non‑binding. Its purpose is to create alignment before due diligence.
- Summarizes price, structure, and key terms.
- Non‑binding except for confidentiality and exclusivity clauses.
- Used to secure access to detailed financial and operational information.
- Sets expectations for due diligence and timelines.
- Allows both sides to confirm interest before drafting legal contracts.
What an Offer to Purchase is
An Offer to Purchase is more formal and often more detailed. Depending on the state and transaction type, it may be binding or partially binding. It is typically used when the buyer has enough information to commit to specific terms.
- More detailed than an LOI, often including specific conditions.
- May be binding depending on jurisdiction and wording.
- Used when the buyer is ready to formalize terms before drafting the final agreement.
- Can serve as a bridge between the LOI and the purchase agreement.
- Often includes contingencies, timelines, and obligations.
Key differences between an LOI and an Offer to Purchase
While both documents outline deal terms, they differ in purpose, timing, and level of commitment.
- LOI is typically non‑binding; an Offer to Purchase may be binding.
- LOI is used early; an Offer to Purchase is used after more information is known.
- LOI outlines high‑level terms; an Offer includes more detail and conditions.
- LOI grants access to due diligence; an Offer often follows initial diligence.
- LOI sets the stage; an Offer moves the deal closer to contract drafting.
When buyers typically use each document
Most small business transactions follow a predictable sequence. Understanding where each document fits helps you stay organized and avoid unnecessary legal work early on.
- Use an LOI when you want to express serious interest and begin due diligence.
- Use an Offer to Purchase when you’re ready to formalize terms after deeper review.
- Move to a Purchase Agreement after due diligence is complete.
- Involve an attorney more heavily once binding agreements are drafted.
- Use each document to build clarity, not pressure.
