IOI & LOI: Nuances of Staging Financial Due Diligence

IOI vs LOI and how the business acquisition process works

Today we’re going to be covering the IOI and the LOI

What they are and how it matters for your deal

If you think about the life cycle of a transaction

sim → IOI → LOI → exclusivity → closing

You want to know where you are in the process and where you need to be going

What is an IOI (indication of interest)

An IOI is an indication of interest

It is a starting bid to gauge interest and valuation range without going deep into due diligence

It is typically non-binding and high level

It sets:

• valuation range
• preliminary structure
• basic timeline

An indication of interest gets you to the table

What is an LOI (letter of intent)

A letter of intent is a formal offer and a roadmap for final negotiation

Once submitted and signed, you begin exclusivity and kick off the process

It sets key deal terms such as:

• purchase price
• structure
• terms of the engagement

A letter of intent commits you to a lane

How the business acquisition process works

The process starts with a sim or marketing materials from the seller

You review the materials and submit an IOI

The IOI is used to narrow the pool of buyers

From there:

• selected buyers move forward
• initial due diligence begins
• conversations with owners take place

Then you submit an LOI

If accepted, you move into exclusivity

This is when full due diligence is executed and the clock starts ticking toward closing

Key differences between IOI and LOI

At the IOI stage:

• you have limited information
• you do not have exclusivity
• you are stress testing the deal to price it

You are answering:

• does this deal check my buy box
• does it produce enough profit
• does it fit my strategy

At the LOI stage:

• you enter exclusivity
• the process becomes confirmatory
• you verify the assumptions behind your purchase price

Walking away at this stage will likely cost you time and money

The common due diligence dilemma

Before the LOI, you don’t want to over diligence

But you also don’t want to under diligence

If you ask too many questions early:

• you may erode seller trust
• you may kill momentum

If you do too little diligence:

• you may lock into terms you cannot finance
• you may be forced to renegotiate later

Submitting an overpriced LOI can:

• position you in a place of weakness
• force a price reduction later

Why what you learn before LOI matters

What you learn before the LOI shapes everything that follows

It sets the stage for a successful business purchase

A strong LOI includes:

• purchase price
• validated earnings
• working capital understanding
• deal structure

This may include:

• cash at closing
• seller note
• earnout structure

Managing seller expectations during exclusivity

Once your LOI is accepted, you enter exclusivity

You are working with your deal team and conducting due diligence

Slow movement equals cold feet

To manage expectations:

• set a kickoff call
• communicate your timeline
• keep requests focused
• explain why you are asking for information

Momentum is leverage

Confident buyers give sellers fewer reasons to re-engage others
