Confidential Information Memorandum (CIM): What's Inside, How to Read One, and Free Template

A CIM is the document where a deal first becomes legible to a buyer.

It's a sell-side document, prepared by the seller's broker or M&A advisor, structured to introduce qualified buyers to the business in enough depth that the buyer can decide whether to commit to diligence and an LOI. The numbers in it are the seller's numbers, normalized with the seller's add-backs. The framing is the broker's framing. None of that is unusual or suspect — every party in an M&A process is presenting their case from their seat. The buyer's job is to pair the document with a structured set of follow-up questions back to the broker.

This post walks through the eleven sections of a typical SMB acquisition CIM, how to read one in passes, what items typically warrant additional follow-up, and how to use the document to decide whether to write an LOI. There's a free CIM template at the bottom — the same structure used in most SMB CIMs. Sellers can use it to prepare for going to market; buyers can use it to know what to expect and what to ask for.

What a CIM is

A confidential information memorandum (CIM) is the document a business broker or M&A advisor sends to qualified buyers after they've signed a non-disclosure agreement.

It runs 30 to 80 pages depending on deal size and contains:

• The business's name and location
• A summary of operations, products, and customers
• Three to five years of financials with seller-prepared adjustments
• Employee structure and management
• Reasons for sale
• An asking price and proposed deal structure
• Growth opportunities the buyer should consider

The CIM is the primary document the buyer uses to decide whether to submit an LOI. It is not a due diligence document. It is not legally binding. It is the seller's prepared introduction — accurate within the data presented, with deeper detail surfaced through the buyer's follow-up questions and the formal diligence process that runs after the LOI is signed.

Teaser versus CIM — the order things happen

Before a buyer sees a CIM, they see a teaser:

• Teaser (1-2 pages, anonymous): industry, revenue range, EBITDA range, geography, asking price range. No business name. Sent to the broker's full buyer list with no NDA required.
• NDA: buyer signs to receive the CIM. Mutual or unilateral; some brokers also require a buyer to disclose net worth and proof of funds.
• CIM (30-80 pages, full disclosure): everything except the trade secrets and customer-by-customer data, which usually appear later under more restrictive access.

For brokers running competitive processes (multiple buyers in parallel), the teaser goes out first to maximize the buyer pool, then NDAs go out, then CIMs follow only to qualified buyers — typically those with verified funds and acquisition experience.

The 11 sections of an SMB acquisition CIM

The structure varies by broker, but a complete CIM covers these eleven sections.

1. Executive summary

One to two pages. The pitch.

What to look for: the broker's framing of the business. Is it described as a "platform acquisition opportunity" (priced as a strategic asset) or a "lifestyle business" (priced as cash flow)? Is the asking multiple at the high end or low end of the industry range? Does the description mention a specific buyer type (search funder, strategic, family office)?

2. Business overview

History, ownership, legal structure, locations, products and services. The narrative version of what the business does.

What to look for: gaps between what's described and what's actually being purchased. If the CIM describes "the business" as having three locations but the asset list later only includes assets at two locations, you're buying a different business than the one being described.

3. Financial summary

Three to five years of:

• Revenue
• Gross profit and margin
• Operating expenses
• EBITDA or seller's discretionary earnings (SDE)
• Capital expenditures

Most CIMs show two views: reported (per the tax return or financial statements) and adjusted (with seller add-backs applied). The asking price is almost always quoted as a multiple of adjusted SDE or EBITDA.

What to look for:

• Revenue trend: stable, growing, declining, or volatile? A 5% revenue decline in the most recent year, treated as a one-time issue, is the most common pattern in CIMs that don't survive diligence.
• Margin trend: are gross margins compressing? In labor-intensive SMBs, that's often the first sign of wage inflation outrunning price increases.
• Add-back ratio: how much do the adjustments add to reported earnings? Add-backs exceeding 25% of reported SDE warrant skeptical review.

4. Products and services

What the business sells, broken down by category. Pricing model. Average ticket size or contract value.

What to look for: revenue concentration by product line. If 70% of revenue is one service offering, the business is more exposed than the topline suggests.

5. Customer profile

The section that drives the most follow-up questions.

What's typically presented at the CIM stage: customer count, channel mix, headline statements like "diversified customer base" with a number such as "over 200 active customers."

What's typically requested in follow-up before LOI: top 10 customers by revenue (named or anonymized), customer concentration percentages, customer churn rate, average customer tenure, and the breakdown of recurring versus project revenue.

The math worth running before submitting an LOI:

• Top customer percentage: a single customer over 20% of revenue is a structural concentration risk that affects both deal price and lender appetite. Above 30%, SBA lenders typically apply a haircut to qualifying earnings or require a customer transition plan.
• Top three customer percentage: above 50% combined, the business is effectively a 3-customer business with a long tail. The buyer needs comfort that those three relationships transfer with the sale, which often means meeting all three before close.
• Top ten customer percentage: a healthy SMB usually sees the top 10 customers at 30-50% of revenue. Above 70% means the long tail is thinner than the count suggests.
• Recurring vs. project revenue: a $3M business with 80% recurring contracts (annual maintenance agreements, retainers, subscription) is materially different from one with 80% one-time projects. The recurring base survives the ownership transition; project pipeline does not transfer the same way and requires the buyer to maintain sales activity from day one.
• Customer churn: monthly customer churn under 1% is excellent for a contracted-revenue business; 2-3% is normal; 5%+ requires explanation. CIMs typically present annual revenue retention rather than churn rate; both numbers are worth requesting.
• Customer acquisition cost (CAC) and LTV: if marketing spend is in the financials, the CAC is computable from new customer counts. LTV/CAC under 3 typically indicates the business is buying growth at low margins.
• Geographic concentration: a $5M HVAC business with 80% of revenue inside a 15-mile radius is local-defensible but capped; the same revenue spread across a metro is more durable but harder to grow incrementally.

6. Marketing and sales

How the business acquires customers. Channel mix, sales cycle, conversion rates, marketing spend, sales team structure.

What's typically in the CIM: channel breakdown ("70% referrals, 20% Google Ads, 10% direct"), monthly marketing spend, lead-to-close conversion rates if tracked, sales rep count and compensation structure.

What to look for:

• Channel concentration: a business with 60% of revenue from Google Ads and no SEO presence is structurally different from one with referral-driven revenue. Paid-channel-dependent revenue is more transferable than relationship-driven revenue, but more vulnerable to ad-cost inflation. Referral-driven revenue is more durable but tied to the seller's reputation.
• Sales cycle length: a 90-day sales cycle for a $50K average ticket means the buyer has 90 days of pipeline visibility post-close and a built-in revenue lag if the seller's outreach stops.
• Customer acquisition channels and post-close ownership: if 40% of revenue comes from "the seller's personal network," that's not a transferable acquisition channel. If 40% comes from inbound SEO, the channel transfers with the website.
• Marketing spend trend: was marketing spend cut in the most recent year? Sometimes that's a one-time efficiency improvement, sometimes it's revenue purchased on the prior year's spend. The TTM revenue should be tested against the trailing-twelve-month marketing spend, not the current run-rate spend.
• Sales team transitions: are sales reps under non-competes? At-will? Paid market or below market? A $1M-quota rep paid below-market is a retention risk in any acquisition.
• CRM and pipeline visibility: businesses on a real CRM (HubSpot, Salesforce, even Pipedrive) hand over a usable pipeline at close. Businesses running on email and spreadsheets hand over the seller's mental Rolodex, which is harder to value and harder to transfer.

7. Operations

Production process, quality control, IT systems, real estate, equipment, inventory, supply chain.

What to look for:

• Equipment age: a CIM that boasts "modernized fleet" without specifying ages may be hiding capex requirements coming up
• IT systems: is it on QuickBooks Desktop and a paper Rolodex, or on a real ERP? The post-close systems migration cost is real
• Lease terms: when does the lease expire? Is there a renewal option? What's the rent escalator? An expiring lease two years post-close is a buyer's leverage in the negotiation
• Inventory: how much is in inventory at any given time? Is it on the balance sheet at cost or write-down? Slow-moving or obsolete inventory often gets adjusted out at close

8. Employees and management

Headcount by department. Key employee retention risk. Management depth. Owner's role.

What to look for:

• Owner's role: how many hours per week? What functions does the owner personally perform that don't transfer? An owner who's selling 60-hour-week customer relationships is selling a different business than one who has a GM running operations.
• Key employee dependency: are there 1-2 employees whose departure would materially harm the business? CIMs rarely volunteer this.
• Compensation structure: are key employees on at-will or under non-competes? Are they paid market or below-market?

9. Real estate, equipment, and assets

What's being conveyed in the sale. Real estate or lease terms. Equipment list with depreciation schedule. Inventory. Fixtures.

The asset side of an SMB acquisition often represents 30-60% of the purchase price allocation, so this section deserves real attention even when the numbers look clean.

Real estate or lease:

• If real estate is owned and included: confirm the seller's basis (often inside the same entity or a related-party LLC), get a current appraisal, and run the deal as a combined real estate + business acquisition. Real estate usually finances on different terms (longer amortization, often 25-year SBA 504) than business goodwill.
• If real estate is owned and excluded: the seller is keeping the building and leasing to the new owner. Confirm proposed lease terms (rate, escalator, length, renewal options, tenant improvement provisions). A seller-leased property at above-market rent reduces deal price; below-market rent boosts SDE in a way that doesn't survive lease renewal.
• If the property is leased from a third party: lease assignment is a closing condition. Confirm the landlord will consent (some require a personal guarantee from the new owner), the lease has at least 5-7 years of remaining term plus options, and rent escalators are documented. Expiring leases are buyer leverage during diligence.

Equipment:

• Get the depreciation schedule, not just the asset list. Equipment fully depreciated on the books is often still operational but may be near replacement age. The schedule shows original cost, useful life, accumulated depreciation, and expected replacement.
• Capex outlook: a fleet of trucks averaging 8 years old in a 10-year-life business signals $X of replacement capex in the first 24 months post-close. Build that into the deal model.
• Leased equipment: items on the asset list that aren't on the balance sheet are often operating leases. Lease assumption (often called "step-in rights") is a closing condition; some leases require lessor consent.
• Excluded equipment: confirm what the seller is taking with them. Personal vehicles, owner's office equipment, and anything explicitly listed as excluded should be cross-referenced against operations to make sure nothing critical leaves with the seller.

Inventory:

• Carrying value: confirm whether inventory is on the balance sheet at cost (first-in-first-out or weighted average) or at lower of cost or market. Slow-moving and obsolete inventory often gets adjusted out at close as part of working capital settlement.
• Inventory aging: request a stratification (under 90 days, 90-180, 180-365, over 365). Inventory over 365 days old in most SMBs is a writedown candidate.
• Inventory verification: a physical count at or near close is standard. The closing balance gets trued up against the working capital target.

10. Growth opportunities

What the seller and broker have identified as upside the buyer could pursue. Geographic expansion, adjacent product lines, pricing optimization, marketing investment.

This section is forward-looking by design — it's where the seller frames the value the buyer is acquiring beyond current performance. A useful read separates two questions:

1. How much of the asking multiple reflects current performance versus projected performance? If the asking price implies 5x SDE based on current TTM plus a "growth opportunity" of doubling revenue in three years, the buyer is paying for execution risk they have to absorb. Confirm the multiple is reasonable on current SDE alone.
2. Are the growth opportunities transferable? "Add a second location" is a transferable opportunity any new owner could pursue. "Use the seller's industry relationships to pursue a major-account program" is not transferable if the seller is leaving. Treat opportunities tied to the seller personally as projection, not value.

11. Reason for sale and asking price

The seller's stated reason for going to market. The asking price. Proposed deal structure (cash vs. seller note vs. earn-out).

The reason for sale carries more diligence weight than buyers typically apply. Common categories:

• Retirement — most common in Main Street acquisitions; lowest baseline concern. Confirm the seller's age and post-close plans (full retirement vs. moving to another business).
• Health — often genuine. Where appropriate, the buyer can request a medical timeline that doesn't compromise privacy but confirms operational ability through transition.
• Pursuing other business interests — confirm the other business isn't competitive, isn't drawing the seller's relationships, and isn't taking the seller's time before close in a way that affects current performance.
• Partnership dispute — request a copy of the operating agreement and any divorce or buyout filings if applicable; the dispute may affect the seller's authority to sign.
• Lifestyle / burnout — a legitimate reason at any age. The follow-up question is whether the burnout reflects a structural change in the business (rising labor costs, customer concentration) or a personal preference unrelated to operations.

What to verify: does the stated reason align with the seller's age, the business's trajectory, and the proposed deal structure? A 45-year-old retiring from a business with three years of revenue decline doesn't necessarily mean anything is wrong, but it's a normal area for additional questions during diligence.

How to read a CIM in 30 minutes — the four-pass method

After reviewing a few hundred CIMs, this is the order I read them in:

Pass 1: Financial summary, asking multiple, reason for sale, customer concentration. If those don't work, stop reading. Should take 5 minutes. About 60% of CIMs fail at this stage.

Pass 2: Add-back schedule, line by line. Compare against the tax returns the broker should have included or sent on request. Each add-back line should have an explanation; if it doesn't, ask. Should take 10 minutes. Common patterns:

• Owner compensation (always added back)
• Owner perks (vehicle, health insurance, family payroll) — sometimes legitimate, sometimes inflated
• "One-time" expenses that recur every year
• Personal expenses run through the business that wouldn't actually transfer

Pass 3: Customer list, employee structure, lease, material contracts, equipment age. Should take 10 minutes. Looking for concentration risks, key-person dependencies, expiring contracts, capex deferred.

Pass 4: Reasons for sale and the structured follow-up question list. Should take 5 minutes. What questions does the CIM not answer? What metrics would normally be in a business this size that this CIM doesn't include? Compile these into a single email to the broker.

If after four passes the deal is still in scope, that's when an LOI is appropriate.

Items that warrant a follow-up question list

Five categories of items typically benefit from additional detail beyond what's in the CIM. These aren't "red flags" — they're the standard set of follow-ups a serious buyer sends back to the broker before committing to an LOI. The broker has the data; this is the part of the process where it surfaces.

1. Customer concentration percentages. When the CIM describes the customer base in summary form ("over 200 active customers, diversified across industries"), the next step is the top 10 customers as a percentage of revenue. This is standard data the seller has and the broker can share — usually anonymized as Customer A, B, C if confidentiality requires.

2. Working capital trends. Required to model the closing working capital adjustment in the LOI. Request 36 months of monthly working capital balances (or, at minimum, 24 months) so seasonality and target are clear. The seller's accountant typically has this readily available.

3. Revenue trend explanation when the most recent year diverges from the prior trajectory. If 2025 revenue dipped while 2022-2024 grew, request a month-by-month breakdown plus the seller's narrative. Most divergences have legitimate explanations — a key customer paused for one quarter, a competitor shut down and the business absorbed pent-up demand the year before, weather, supply chain. The math determines whether the new trajectory should be projected forward or the trailing twelve months remain the right number.

4. Add-back schedule with supporting documentation. When add-backs exceed 25% of reported SDE, request the underlying support: receipts for personal expenses, board-approval minutes for one-time items, comparable-market data for owner compensation normalization. SBA lenders will require this in underwriting; the buyer is wise to pre-validate before LOI rather than finding out later.

5. Post-close transition and seller availability. The CIM typically mentions the seller's role; the follow-up establishes specifics. How many hours per week will the seller commit to transition? For how long? Will the seller introduce key customers in person? Is the seller open to a 24-month consulting agreement at a defined rate? These terms get codified in the APA, but the conversation starts before LOI.

The pattern across all five: a thorough buyer review produces a structured Q&A list — not because anything is wrong with the CIM, but because the CIM is the introduction, and the questions are how the buyer moves toward an LOI with the right information.

Free CIM template

Sellers preparing to go to market can use this template as a starting structure. It covers the 11 standard sections, with prompts for financials, customer data, and growth opportunities. For deals under $1M, a templated CIM with seller input is usually sufficient.

Download the CIM template →

For deals above $1M, working with a broker who prepares the CIM professionally typically produces a sale price 10-15% higher because of how presentation affects buyer pool size and competitive tension. The template is a teaching tool, not a substitute for a broker on a meaningful deal.

After the CIM: the follow-up loop before LOI

A buyer who finishes reading a CIM and decides to engage typically takes three steps, in order, over the following 7-14 days:

Step 1: Send a structured follow-up question list to the broker. This is a single email or document organized by CIM section. Specifics that are standard to request:

• Financials: monthly P&L for the past 36 months; balance sheets at month-end for the past 24 months; tax returns for the past 3 years; the add-back schedule with line-by-line documentation; bank statements for the past 12 months (often released only to qualified buyers under a tighter NDA).
• Customers: top 10 customers as a percentage of revenue, anonymized if needed; customer churn or revenue retention by year; recurring vs. project revenue mix; top 3 customer contract terms (length, auto-renewal, change-of-control clauses).
• Operations: equipment depreciation schedule; lease document for any leased premises; key vendor contracts; any unusual one-time events in the most recent two years and their financial impact.
• Employees: full headcount with roles, tenure, base, and variable comp; key employee retention agreements or non-competes if any; the owner's hours per week and specific functions performed.
• Seller transition: proposed transition period, hours of seller availability post-close, openness to a consulting agreement, customer introduction commitments.

Step 2: Schedule a call with the seller. Usually 60-90 minutes, sometimes mediated by the broker. The call is for the questions a document can't answer: how the seller talks about the business, what energizes them and what frustrates them, how they describe their team and customers, what they would do differently if they were starting over. The financial questions get answered in writing; the operational and cultural questions get answered live.

Step 3: Draft and submit the LOI. Based on what the CIM, the Q&A response, and the seller call revealed. The LOI prices the deal, structures it, and locks exclusivity for diligence.

For the LOI structure, see our letter of intent guide. For the financing math that turns the CIM's asking price into a financeable purchase price, see our forthcoming SBA loan calculator and DSCR walkthrough. For the SDE adjustments that drive both the price and the eventual indemnification, our SDE calculation guide walks through the line items lenders accept.

The CIM is not the document that determines whether you buy a business. It's the document that determines whether you write an LOI. The follow-up loop in between is what makes the LOI defensible.
