An expression of interest is a non-binding written statement that you want to be considered for a transaction, contract, visa program, or acquisition, submitted before anyone drafts formal offers or commits resources. It lets the receiving party screen candidates early, and it lets you test the waters without locking yourself into terms. The specifics shift depending on whether you’re bidding for a government contract, eyeing a property, applying for skilled migration, or circling a company you’d like to buy, but the core function is the same across all of them.
Where You’ll Encounter One
EOIs appear whenever a process attracts more interested parties than the receiving organization can evaluate through full applications. The document acts as a filter.
Government Procurement
Agencies issue a request for expressions of interest to identify qualified vendors before launching a formal solicitation. Respondents who pass the initial screen then receive a Request for Proposal. The United Nations Procurement Division spells this out directly in its EOI notices, stating that the request “is not a Request for Proposal” and that detailed specifications will follow in the RFP itself.1United Nations Procurement Division.

Real Estate
A prospective buyer submits an EOI to signal intent to purchase at a particular price before anyone drafts a formal purchase agreement. Under basic contract principles, this kind of preliminary communication is not a binding offer. It sits closer to what contract law calls a preliminary negotiation: a signal of willingness to deal that the other party can accept, reject, or counter without legal commitment on either side.
Commercial EOIs typically carry more detail than residential ones. Buyers often flag early contingencies around financing, inspections, zoning verification, and title review. Getting these details right at the EOI stage matters because serious inconsistency between your preliminary numbers and your later formal offer can undermine your credibility with the seller.
Immigration Selection Systems
Several countries run merit-based immigration through EOI systems. Australia’s SkillSelect requires applicants for certain skilled visas, including the Skilled Independent (subclass 189), Skilled Nominated (subclass 190), and Skilled Work Regional (subclass 491), to submit an EOI before they can be invited to apply. These are points-based visas, and you need to meet or exceed a threshold of 65 points to be considered for an invitation.2Department of Home Affairs. Expression of Interest
Canada’s Express Entry works similarly. Candidates enter a pool, get ranked, and the highest scorers receive an Invitation to Apply for permanent residence. That invitation is valid for 60 days.3Government of Canada.

Mergers and Acquisitions
In M&A, an EOI (sometimes called an indication of interest) is how a potential buyer tells a target company or its advisors that it wants to explore an acquisition. It usually outlines broad terms such as a valuation range, likely deal structure, and the buyer’s rationale, without binding either party. If the target likes what it sees, it invites the buyer into deeper due diligence, management meetings, and eventually a formal Letter of Intent. The due diligence phase alone often runs 90 days or longer.
How an EOI Differs From a Letter of Intent
People frequently confuse these two documents, and the distinction matters.
An EOI conveys general interest. It says “we’d like to be considered” without proposing specific terms or restricting either party’s freedom. You can submit EOIs to multiple parties at once and walk away from any of them without consequence.
A Letter of Intent goes further. It outlines proposed deal terms such as price, timeline, and conditions, and signals a more concrete commitment to proceed under those terms if negotiations go well. While an LOI is not typically a fully binding contract, it often contains individually binding provisions covering confidentiality, exclusivity, or allocation of costs during due diligence. An EOI almost never includes binding clauses of any kind. The EOI raises your hand; the LOI shakes hands on the outline of a deal.
What Goes Into an EOI
The exact requirements depend on who’s asking, but most EOIs require you to establish three things: who you are, whether you can afford what you’re pursuing, and whether you have the qualifications to follow through.
Identity
Every EOI starts with verifying your legal identity. Individuals submit government-issued identification. Businesses provide corporate registration details and tax identification numbers. Make sure all names and dates match your official records exactly, because discrepancies between the EOI and your later formal documents create administrative delays and can get you disqualified.
Financial Capacity
Recipients want evidence you can actually complete the transaction. Depending on the scope, this might mean bank statements, audited financial reports, or a letter of credit from a financial institution. The required proof scales with the opportunity. A small services contract might call for documentation of modest working capital; a large infrastructure bid could require evidence of credit lines in the millions. Providing this early reduces the risk of a deal collapsing from a liquidity shortfall later.
Qualifications
For procurement EOIs, you typically need to demonstrate a track record through past performance records, references from completed contracts, and industry certifications. Having relevant insurance already in place matters here too, because scrambling to arrange coverage under deadline pressure once you reach the formal bid stage rarely goes well.
Real Estate Specifics
Real estate EOIs typically use proprietary forms from the listing agency. You fill in your proposed purchase price, preferred closing timeline, and any contingencies you want to flag early. In commercial transactions, you may also need to describe your intended use for the property, since zoning restrictions could make the deal impossible.
What Non-Binding Doesn’t Cover
Under the Restatement (Second) of Contracts, a communication does not qualify as an offer if the recipient knows or should know that the sender doesn’t intend to finalize a deal without further agreement. An EOI fits squarely within that definition of a preliminary negotiation. It expresses willingness to explore, not willingness to be bound. But “non-binding” has limits that catch people off guard.
Promissory Estoppel
If your EOI makes a specific promise that causes the other party to take costly action in reliance on it, you can face liability under promissory estoppel even without a signed contract. The Restatement (Second) of Contracts §90 provides that a promise the promisor should reasonably expect to trigger reliance, and that does trigger reliance, becomes enforceable “if injustice can be avoided only by enforcement of the promise.”5Cornell Law School. Promissory Estoppel An EOI that goes beyond expressing general interest, with specific commitments about price, timeline, or exclusivity, can create enforceable obligations if the other side reasonably relies on them and suffers a loss. Keep EOI language general enough that it doesn’t read like a promise.
False Statements
An EOI doesn’t bind you to complete a transaction, but it absolutely binds you to tell the truth. In federal procurement, the Federal Acquisition Regulation warns that bidders must provide “full, accurate, and complete information” and that the penalty for false statements is prescribed under federal criminal law.6Acquisition.GOV. 52.214-4 False Statements in Bids Under 18 U.S.C. § 1001, knowingly making a false or fraudulent statement to a federal agency is punishable by up to five years in prison and fines.7Office of the Law Revision Counsel. 18 USC 1001 – Statements or Entries Generally That applies to any material misrepresentation: inflated revenue figures, fabricated past performance, false certifications. The preliminary nature of the EOI provides no shield.
Outside federal procurement, submitting fraudulent information in an EOI can result in disqualification, blacklisting from future opportunities, and civil liability. In immigration systems, false information can trigger visa refusal and bars on future applications.
Protecting Information You Share
An EOI often requires you to share sensitive business information with a party you haven’t yet entered a formal relationship with. How that information is protected depends on the context.
In M&A, a confidentiality agreement (often called a non-disclosure agreement) is typically the first document signed. For private companies, the NDA usually comes before the target shares any meaningful information with a potential buyer. For public companies, the seller may want to see a credible indication of interest first. These agreements restrict disclosure that negotiations are even happening, limit who inside the buyer can access the data, and require destruction or return of confidential materials if the deal falls through. Breach remedies usually include the right to seek injunctive relief, meaning a court order to stop disclosure rather than just damages after the fact.
Federal procurement provides its own protections. Contractor bid and proposal information cannot be disclosed to anyone not specifically authorized by the agency head or contracting officer. If you’re submitting proprietary data, mark each page containing sensitive information with the legend “Source Selection Information—See FAR 2.101 and 3.104.” Some categories of information receive protection regardless of marking, but making reasonable efforts to label your materials strengthens your position if a dispute arises. If a contracting officer believes your proprietary markings are unjustified, they must notify you in writing and give you a chance to explain before removing the markings or releasing the information.8Acquisition.GOV. FAR 3.104-4 – Disclosure, Protection, and Marking of Contractor Bid or Proposal Information and Source Selection Information
After You Submit
Review timelines vary. A straightforward commercial EOI might be evaluated in a few weeks. Government procurement reviews, where evaluators score submissions against weighted technical criteria, can run several months. Immigration EOIs sit in a ranked pool indefinitely until the applicant either receives an invitation or lets the EOI expire.
A successful EOI leads to a more rigorous stage. In procurement, you receive a formal Request for Proposal where detailed specifications, pricing, and contract terms get negotiated. In immigration, you receive an Invitation to Apply. In M&A, the target company grants access to deeper financial and operational data for formal due diligence. Response deadlines for these invitations are strict. Both SkillSelect and Express Entry give 60 days to complete the full application after an invitation issues, and missing the window typically means your EOI expires and you lose your place.4Department of Home Affairs.

You can withdraw an EOI or a later proposal before an award is made. In federal procurement, proposals may be withdrawn by written notice at any time before award, and oral proposals may be withdrawn orally.9Acquisition.GOV. FAR 15.208 – Submission, Modification, Revision, and Withdrawal of Proposals Federal acquisition rules do not impose any penalty on your future bidding eligibility for withdrawing. The contracting officer retains one copy of the withdrawn submission in the contract file, and electronically transmitted materials are purged from agency systems where practicable. In non-government contexts, withdrawal is even simpler. Since the EOI is non-binding, you can notify the recipient and walk away.
