What is a CIM and do I need one to sell my business?
The CIM (also called an offering memorandum, or 'the book') is the primary marketing and information document in a business sale, and it sits in a fixed sequence. A one-to-two-page anonymous teaser goes out first; interested buyers sign an NDA; the CIM follows; buyers respond with indications of interest (IOIs); the seller negotiates a letter of intent (LOI) with the chosen buyer; then due diligence verifies everything the CIM claimed before closing. Its job is to give a serious buyer enough to make a credible offer without handing sensitive details to tire-kickers or competitors.
A good CIM usually covers: an executive summary; company history and ownership; products or services; customers and contracts (often anonymized, with concentration shown in bands rather than names); the management team and staffing; 2-3 years of financials with normalized SDE or EBITDA and defensible, documented add-backs; growth opportunities a buyer could actually execute; and a clear, honest reason for selling.
Accuracy is the whole game. Every claim in the CIM gets tested in due diligence — buyers re-derive the EBITDA bridge, verify add-backs against payroll and bank records, and check customer concentration against invoices. Anything overstated does not just get caught; it gets repriced, usually late in the process when the seller has the least leverage. A conservative, verifiable CIM tends to produce fewer retrades than an aggressive one.
Whether a formal CIM is needed depends on the buyer and the deal size. For a very small, simple sale to an individual buyer, a tight financial summary may be enough. But in any process involving private-equity firms, search funds, or strategics — where pricing is on EBITDA and diligence is rigorous — a professional CIM is effectively expected and materially helps the outcome.
The CIM is typically prepared by the seller with an advisor, broker, or M&A partner, working from the company's real financials. DealSeam is a deal origination company, not a traditional business broker; it helps owners package the business and introduces them to qualified buyers where there's a fit, with the buyer paying the success fee.
Related questions
What's the difference between a teaser and a CIM?
A teaser is a one-to-two-page anonymous summary used to gauge buyer interest before any NDA. The CIM is the full, named document with financials and operating detail, shared only after a buyer signs an NDA.
When is a CIM shared in the sale process?
After a buyer expresses interest and signs an NDA, and before they submit a letter of intent. It gives qualified buyers what they need to make a credible offer while keeping sensitive details confidential.
What goes in a CIM?
An executive summary, company background, products or services, a customer and contract overview, management and staff, 2-3 years of financials with normalized SDE or EBITDA, growth opportunities, and the reason for selling.
Do I need a CIM to sell a small business?
Not always. A very small sale to an individual buyer may only need a clean financial summary. But once private-equity or strategic buyers and EBITDA-based pricing are involved, a clear CIM is effectively expected and improves your result.
Who writes the CIM?
It's typically prepared by the seller with help from an advisor, broker, or M&A partner. The key is accuracy - every claim should survive due diligence, because buyers verify it before closing.
Is a CIM legally binding?
No. The CIM is an informational and marketing document, normally covered by the NDA rather than creating obligations itself. The binding commitments come later - in parts of the letter of intent and, above all, the purchase agreement, whose representations and warranties are what a seller formally stands behind.
