The M&A Advisor & Business Broker Toolkit: Complete Checklists, Templates, and Deal Workflow (2026)
Every business sale runs through the same seven stages — from the engagement letter that establishes the advisory relationship to the closing funds flow that wires the proceeds. What separates experienced advisors from new practitioners is not intelligence or personality. It is knowing exactly which document is required at which stage, why each clause exists, and what breaks when one element is missing or poorly structured.
This guide covers the complete toolkit across all seven stages of a business sale — every document, checklist, and template a business broker or M&A advisor needs to operate professionally. Both main street brokerage workflows (owner-operated businesses under $5M) and lower-middle-market advisory processes ($5M–$50M institutional-quality engagements) are covered, with clear callouts where they differ.
How to use this guide: Read sequentially for a full deal workflow education, or jump directly to the stage you need using the navigation panel. The due diligence checklist in Stage 6 and the VDR folder tree are the most referenced standalone resources — bookmark the page for repeated use.

01 Stage 1Client Retention & Fee Security
Stage 1Client Retention & Fee Security
The engagement documents signed at Stage 1 establish everything that follows: the scope of the advisory relationship, the advisor's compensation, the seller's obligations, and the legal protection that ensures the advisor is paid if a deal closes. A weak engagement document is the most common reason competent advisors close deals and receive nothing. Get this stage right before anything else.
M&A Engagement Letters vs Main-Street Business Brokerage Listing Agreements
M&A Engagement Letter (LMM · $5M+)
PurposeEstablishes advisory relationship for sell-side M&A process. Multi-page document with detailed scope of services, process description, and comprehensive fee protections.
Fee structureMonthly retainer ($10K–$30K) credited against success fee at close. Success fee via Modified Lehman or negotiated structure. Sometimes includes minimum fee floor.
ExclusivityAlways exclusive — seller may not engage other advisors or transact independently during the term.
TermTypically 12–18 months. Auto-renews or expires; termination provisions with notice period (30–90 days).
ScopeDetailed services listed: preparation of CIM, buyer outreach, management presentations, due diligence management, negotiation support.
Tail periodTypically 18–24 months for buyers introduced during engagement. Carve-out list negotiated upfront.
State licenceMay require investment banking registration or state securities licence in some jurisdictions for deals above certain thresholds.
Business Brokerage Listing Agreement (Main Street · <$5M)
PurposeEstablishes brokerage relationship for sale of a business. Simpler document — typically 2–5 pages. Covers pricing, commission, and basic terms.
Fee structureSuccess fee only in most cases (no retainer). Flat percentage (8–12%) or minimum fee ($15K–$25K) whichever is greater.
ExclusivityExclusive right to sell (most common) vs exclusive agency (seller can sell independently without paying commission). Negotiate explicitly.
TermTypically 6–12 months. Renewal by mutual agreement or auto-expiry.
ScopeLess detailed — typically states "broker will use reasonable efforts to market the business." Some list specific marketing activities.
Tail periodTypically 12–18 months. Carve-out list important but often not included — negotiate proactively.
State licenceSome states require real estate licence for business sales (CA, FL, TX, AZ, CO). See licensing guide →
Success Fee Schedules: Lehman vs Fixed Percentage
The fee schedule is the single most negotiated element of any engagement document. Both parties need to understand precisely how the success fee is calculated before signing — disputes about fee calculation are among the most common post-close professional disputes in brokerage. For full fee structure detail and interactive calculations, see the fee calculator →.
Fee schedule language — key structural elements to include
CALCULATION BASIS: Success Fee shall be calculated on the "Aggregate Transaction Value" (ATV), defined as the total consideration paid or payable for the Business, including: (i) cash paid at Closing; (ii) the face value of any Seller Notes; (iii) the maximum potential payout under any Earnout provisions; (iv) the fair market value of any non-cash consideration; (v) assumed indebtedness; and (vi) any post-closing adjustments paid to Seller.
Note: "Gross proceeds" vs "net proceeds" definition determines whether the fee includes assumed debt. Negotiate to include only amounts actually received by seller if possible.
EARNOUT FEE TIMING: The Success Fee attributable to any Earnout portion of the Aggregate Transaction Value shall be paid to Advisor within 10 business days of the date on which Seller receives the applicable Earnout payment.
Without this clause, advisors often receive the full fee at closing calculated on maximum earnout — but if the earnout is not achieved, there is no mechanism for the seller to recover the excess fee paid.
MINIMUM FEE: Notwithstanding the above calculation, the Success Fee shall not be less than $[AMOUNT] regardless of the Aggregate Transaction Value.
For main street brokers: $15K–$25K minimum. For LMM advisors: $100K–$250K minimum. Protects advisor economics on smaller-than-expected deals.
Tail Period Clauses and Carve-Out List Templates
The tail period is the advisor's protection against being fired after doing all the work — ensuring the success fee is paid if the seller completes a transaction with any buyer the advisor introduced, even after the engagement terminates. It is the most contested clause in brokerage agreements and the one most likely to produce post-close disputes.
Tail period clause — model language
TAIL PERIOD: In the event this Agreement is terminated for any reason, Advisor shall be entitled to a Success Fee if, within [24] months following the date of termination (the "Tail Period"), Seller completes a Transaction with any Buyer or Buyer group: (i) to whom Advisor introduced Seller during the Term of this Agreement; (ii) who received any marketing materials from Advisor during the Term; or (iii) with whom Advisor conducted any discussions regarding the Business during the Term.
Key drafting point: "introduced" should be defined. Did attending a luncheon where the buyer was present constitute an "introduction"? Define with specificity to avoid disputes.
CARVE-OUT LIST: Notwithstanding the foregoing, the following Buyers, identified by Seller prior to execution of this Agreement, are excluded from the Tail Period provision (the "Carve-Out List"): [SCHEDULE A — LIST OF NAMED BUYERS]. The Carve-Out List may not be amended after execution without written consent of Advisor.
The carve-out list must be agreed and attached BEFORE signing. Sellers who want to add names after signing are trying to exclude buyers the advisor has already worked to identify — do not accept post-execution additions.
Practical carve-out list guidance: sellers should identify 3–10 named potential buyers (competitors, strategic partners, known interested parties) they have already had conversations with before engaging an advisor. These are the sellers' own relationships — the advisor did not originate them. The carve-out list protects the seller from paying a commission on a deal they would have closed independently. Everything not on the carve-out list is the advisor's protected territory for the tail period.
02 Stage 2Confidential Marketing
Stage 2Confidential Marketing
The marketing stage produces the documents that buyers see — and the process controls that ensure they see them only under the right conditions. Every document in this stage is either designed to protect the seller's confidentiality (the anonymous teaser, the NDA) or to present the business compellingly to qualified buyers (the CIM or broker profile). The sequence matters: teaser → NDA → CIM, never in a different order.
The One-Page Anonymous Investment Teaser
The anonymous teaser is the first document sent to prospective buyers. It contains enough information to determine whether the opportunity matches the buyer's criteria, but not enough to identify the specific business. Its sole purpose is to generate interest and a request for the NDA and full marketing document.
Include in the teaser
Revenue and earnings rangeApproximate figures in a range — "Revenue $1.8M–$2.2M · SDE $380K–$420K" — confirming deal size without revealing specific figures
Business type descriptionGeneral sector and service description: "Residential HVAC service and installation company" — enough to confirm relevance, not enough to identify
Geographic regionState or region, not city. "Southeast United States" not "Nashville, Tennessee"
Key investment highlights3–5 anonymous bullet points: "65% recurring maintenance contract revenue," "4 licensed technicians, team remaining post-close," "20-year customer relationships"
Asking price rangeOptional — include if it filters unqualified buyers. "Listed at $1.6M" prevents time wasted on buyers who cannot fund the deal.
CTA and NDA instruction"For a confidential information memorandum, execute and return the attached NDA to [contact]."
Never include in the teaser
Business name or DBAEven "Bob's HVAC" in a small market is identifying. Use a code name or omit entirely until NDA is signed.
Specific locationCity, address, or any geographic identifier specific enough to identify a business in a regional search
Key customer namesEven describing a major customer as "a Fortune 500 manufacturing company" can be identifying in a niche sector
Exact financial figuresSpecific revenue or earnings numbers allow sophisticated buyers to triangulate the business identity from public records or competitor knowledge
Owner informationNo names, LinkedIn profiles, or background details that identify the seller
Photos or brandingBuilding photos, uniforms, vehicles, or any branded imagery that makes identification possible
Business Broker Profiles vs Institutional CIMs
Both documents serve the same purpose — presenting the business to qualified, NDA-signed buyers in a way that supports a decision to submit an offer. The difference is depth, audience, and production quality, which reflect the different buyer pools at different deal sizes.

Standard Business Sale Non-Disclosure Agreements
The NDA is signed before any identifying information about the business is disclosed. It is a binding legal agreement obligating the buyer not to disclose the information received, not to use it for any purpose other than evaluating the acquisition, and not to contact employees, customers, or suppliers directly without the seller's consent.
Critical NDA clauses for business sales
NON-SOLICITATION OF EMPLOYEES: For a period of [24] months from the date of this Agreement, Recipient shall not, directly or indirectly, solicit, recruit, or hire any employee of the Company, whether or not such employee was identified through Confidential Information.
This clause survives deal failure. A buyer who enters your business's data room, identifies your best employees, and hires them away after declining to buy is a real and documented risk in competitive sectors.
STANDSTILL PROVISION: Recipient shall not, for a period of [12] months from the date hereof, directly or indirectly, approach any customer, supplier, or counterparty of the Company without the prior written consent of the Company.
Particularly important for businesses where the buyer is a competitor. Without this clause, competitors can use the due diligence process as competitive intelligence gathering.
RETURN OF INFORMATION: Upon request, Recipient shall promptly return or destroy all Confidential Information and certify in writing that all copies have been returned or destroyed.
Define "Confidential Information" broadly — including notes, analyses, and derivative works created from the disclosed information, not just the original documents.
03 Stage 3Valuation, Normalisation & SDE Modelling
Stage 3Valuation, Normalisation & SDE Modelling
The financial package produced at Stage 3 is what buyers and their advisors use to determine whether to make an offer and at what price. The quality of the normalisation work — how completely and defensibly the financial statements have been restated to show true earnings — directly determines the valuation range the business commands in the market. For full valuation methodology detail, see the business valuation methods guide →.
SDE Add-Back Spreadsheet: Structure and Key Line Items
The SDE add-back workbook is the foundational financial document for any main street business sale. It takes the reported net profit and rebuilds it to show the true cash benefit to a single owner-operator. Every line item must be documentable — tied to a specific tax return line, bank statement entry, or payroll record. Undocumented add-backs will be challenged and removed during buyer due diligence.

EBITDA Normalisation and NWC Peg for LMM Deals
For LMM deals ($5M+ enterprise value), the primary earnings metric is normalised EBITDA — EBITDA adjusted to show recurring, maintainable earnings of a manager-run business. The NWC (Net Working Capital) peg is the agreed target level of working capital to be delivered at closing, preventing price chips and post-close disputes about whether the business was delivered with sufficient operational liquidity.
- EBITDA normalisation adjustments (parallel to SDE add-backs but for manager-run businesses): above-market executive compensation, one-time legal or restructuring costs, non-cash charges (stock-based compensation, earnout revaluations), COVID-era stimulus received (normalised out), sponsor management fees (for PE-owned businesses), and transaction costs expensed ahead of the sale.
- NWC peg methodology: Calculate average normalised NWC over the trailing 12 months on a monthly basis. The peg is the average — typically confirmed via a closing NWC statement. If delivered NWC at closing exceeds the peg, the buyer pays the difference; if it falls short, the purchase price is reduced dollar-for-dollar. The NWC peg negotiation is one of the most contested elements in LMM deal closing and must be agreed in the LOI, not negotiated during due diligence.
- EBITDA bridge: A formal reconciliation from reported EBITDA to normalised EBITDA, showing each adjustment line by line with documentation. Buyers will prepare their own EBITDA bridge during due diligence — the seller's bridge establishes the starting position for those conversations.
Broker Opinion of Value Framework
A BOV (Broker Opinion of Value) is an informal valuation prepared by the advisor for the seller client — distinct from a formal appraisal (which follows USPAP standards and can be used in legal, tax, or regulatory contexts). The BOV's purpose is to help the seller set a defensible asking price and understand how buyers will evaluate the business financially.
A professional BOV contains: (1) normalised financial summary (3 years + TTM); (2) primary valuation method applied with multiple justification tied to comparable transactions; (3) secondary method cross-check; (4) adjusted NAV floor value; (5) risk factor analysis with multiple compression rationale; (6) concluded value range with asking price recommendation; (7) key assumptions and their basis; and (8) the IBBA-standard disclaimer that the BOV is not a certified appraisal and is subject to revision upon further due diligence. The disclaimer is not boilerplate — it protects the advisor from liability if the ultimate sale price differs from the BOV range.
04 Stage 4Main Street Brokerage vs LMM M&A Execution
Stage 4Main Street Brokerage vs LMM M&A Execution
The execution workflow for a $500K main street business sale and a $15M lower-middle-market advisory mandate look fundamentally different — in timeline, buyer pool management, deal tracking, and the formality of every interaction. Understanding both workflows allows an advisor to apply the right process to each engagement rather than using an institutional process for a simple transaction or a casual process for a complex one.
Main-Street Business Broker Toolbox
- Buyer qualification form. A one-to-two-page questionnaire completed by every interested buyer before receiving detailed financial information. Includes: estimated acquisition budget, current occupation, relevant experience, general financing approach, and reason for interest. Filters serious buyers from casual inquirers before the advisor invests time in a full presentation.
- Co-brokerage agreement. When another broker introduces a qualified buyer, a co-brokerage agreement establishes how the commission is split. Typical splits: 50/50 or 60/40 in favour of the listing broker. The agreement must be signed before the buyer is introduced to the seller and must specify: fee split formula, which broker's NDA governs, and who manages due diligence and closing. For IBBA co-brokerage standards, see the IBBA ethics guidelines.
- Buyer-broker registration form. Confirms that a specific buyer was registered by a specific broker on a specific date, establishing priority in cases where multiple brokers attempt to claim credit for introducing the same buyer.
- Escrow instruction letter. Sent to the escrow/title company at the opening of escrow, specifying: the parties to the transaction, the purchase price, earnest money deposit amount, required documents for closing, and the fee disbursement instructions (broker commission from seller proceeds). Without clear escrow instructions, the closing can be delayed waiting for the escrow officer to confirm fee payment mechanics.
LMM M&A Deal Architecture: Auction Logs and Buyer Tracking
- Buyer universe map. A structured spreadsheet of all potential acquirers categorised by type (strategic, financial sponsor, family office, independent sponsor, management team), relationship strength, likely interest level, and known deal criteria. Built before the marketing launch and managed throughout the process.
- Buyer outreach log. Records every buyer contact: date, method, response, NDA status, CIM received date, and follow-up schedule. In a controlled auction with 40–100 buyer contacts, systematic tracking prevents buyers falling through and ensures every qualified party receives equal process treatment.
- IOI / LOI tracking grid. Maintains all indications and letters of interest received, sortable by bid price, structure (cash vs earnout), due diligence requirements, and buyer credibility. Used to manage the bid selection process and communicate status to the seller.
- Process letter. Sent to all CIM recipients establishing the process timeline: IOI submission deadline, LOI deadline, management presentation schedule, exclusivity period, and closing target. Sets expectations and creates competitive dynamics that prevent buyers from stalling.

Small Business Offer to Purchase vs Enterprise LOI
For main street business sales, many transactions use a simplified "Offer to Purchase" or "Purchase Agreement in Principle" rather than a formal Letter of Intent. The main street Offer to Purchase typically covers: purchase price, asset vs stock structure, financing contingency (SBA approval), due diligence period and conditions, earnest money deposit, and closing timeline. Unlike a formal LOI, it may include a financing contingency that allows the buyer to exit if SBA financing is not obtained within a specified period — a provision that is rare in LMM LOIs where institutional buyers are typically not SBA-dependent.
Standalone Exclusivity and No-Shop Agreements
The exclusivity provision (also called a no-shop or standstill) grants a single buyer the right to complete due diligence without competition from other buyers for a specified period. It is the most valuable thing a seller can give a buyer short of signing the definitive agreement — and it should only be given to a buyer who is serious, credentialed, and has submitted a price and structure that meet the seller's minimum requirements.
Exclusivity provision — key drafting elements
EXCLUSIVITY PERIOD: For a period of [60] days from the date of this Letter of Intent (the "Exclusivity Period"), which may be extended by mutual written agreement, Seller shall not, directly or indirectly: (i) solicit, initiate, or encourage any offer or inquiry from any third party with respect to a Transaction; (ii) provide any information to any third party in connection with a potential Transaction; or (iii) enter into any agreement with any third party with respect to a Transaction.
60 days is standard for LMM. 30 days for simpler main street deals. Shorter exclusivity periods create urgency; longer periods give buyers insurance for complex due diligence. Never grant unlimited exclusivity.
TERMINATION OF EXCLUSIVITY: Exclusivity shall terminate immediately if: (i) Buyer fails to provide evidence of financing capability within [15] business days of the date hereof; (ii) Buyer materially reduces the purchase price or changes the transaction structure without the written consent of Seller; or (iii) Buyer fails to conduct due diligence in good faith and with reasonable diligence during the Exclusivity Period.
The "good faith" termination trigger protects sellers from buyers who use exclusivity as a parking mechanism with no genuine intent to close. Include specific milestones — management meeting, VDR review completion, financing commitment letter — within the exclusivity period.

VDR access should be staged — buyers see financial summaries and marketing materials first, then full financial detail after LOI, then employee and customer name-level data only under confirmed exclusivity. Never give full VDR access at the CIM stage.
07 Stage 7Definitive Closing Documentation & Title Transfer
Stage 7Definitive Closing Documentation & Title Transfer
Asset Purchase Agreements vs Stock Purchase Agreements
Asset Purchase Agreement (APA)
What transfersSpecific listed assets: equipment, inventory, customer contracts, trade names, IP, goodwill. Buyer selects which assets to include and which liabilities to assume.
LiabilitiesBuyer assumes only specifically listed liabilities. Unknown or undisclosed liabilities generally remain with the seller entity.
Tax implications for buyerStep-up in asset basis to purchase price — allows buyer to depreciate assets from current value. Generally more favourable for buyers.
Tax implications for sellerGains taxed at asset level — mix of ordinary income (inventory, receivables, equipment recapture) and capital gains (goodwill, certain IP). Often less favourable for sellers.
Contract transferabilityCustomer and supplier contracts must be assigned — some require third-party consent. More complex for businesses with many contracts.
Most common useSmall businesses under $5M, asset-heavy businesses, LLCs and sole proprietorships, any situation with potential unknown liabilities.
Stock (or Membership Interest) Purchase Agreement (SPA)
What transfersOwnership of the entire legal entity — all assets AND all liabilities, disclosed and undisclosed, transfer to the buyer with the entity.
LiabilitiesBuyer assumes ALL liabilities — including unknown, contingent, or undisclosed. Reps and warranties in the SPA (and W&I insurance) provide protection.
Tax implications for buyerNo step-up in asset basis. Buyer inherits the seller's historical tax basis. Generally less favourable for buyers; sometimes mitigated by IRC 338(h)(10) election.
Tax implications for sellerGains taxed as capital gains on sale of stock — single layer of taxation (vs double-tax risk in C-corp asset sales). Generally more favourable for sellers.
Contract transferabilityContracts remain with the entity — no assignment required. Simpler for businesses with many existing contracts. Government contracts may have change-of-control provisions.
Most common useC-corporations, businesses with significant government or enterprise contracts that are non-assignable, larger LMM transactions where liability profile has been confirmed in due diligence.
Disclosure Schedules, Seller Notes, Escrow and Closing Documents
The APA or SPA is accompanied by a suite of ancillary documents that together constitute the complete closing package. Each serves a specific function and must be correctly executed for the transaction to be legally complete.
- Disclosure schedules. Attached to the purchase agreement, the disclosure schedules contain the seller's specific disclosures qualifying the representations and warranties — the list of known exceptions to the seller's statements about the business. Key schedules: pending litigation, material contracts, intellectual property owned, employee agreements, real estate leases, material customers, and any known undisclosed liabilities. The quality of the disclosure schedules determines the seller's post-close liability exposure — inadequate schedules leave the seller exposed to indemnification claims.
- Seller promissory note. Documents the seller financing component of the deal — principal amount, interest rate, payment schedule, security interest (typically a UCC lien on business assets), default events, and acceleration provisions. The note is executed simultaneously with the APA/SPA at closing. For the SBA 80/10/10 structure, the note must meet SBA standby requirements — no payments for the standby period, subordinated to the SBA lender's senior position. See the seller financing guide →
- Transition Services Agreement (TSA). When the seller is staying on to support the transition (most retiring owner acquisitions), the TSA governs the post-close period: the seller's role and responsibilities, compensation during transition, the timeline and conditions for full handover, what happens if the seller leaves early, and the seller's non-compete obligations. The TSA should be negotiated and attached to the purchase agreement at closing — post-close TSA disputes are significantly less likely when the terms are agreed before the deal closes.
- Closing funds flow memorandum. Prepared by the closing attorney or escrow officer, the funds flow memo shows exactly where every dollar goes at the closing table: buyer wire to escrow → disbursement to seller (net of liens and fees) → disbursement to SBA lender (if applicable) → disbursement to broker (success fee) → disbursement to transaction attorneys (fees) → return of buyer's earnest money deposit into closing consideration. Both parties should review and approve the funds flow memo the day before closing to prevent delays at the table.
- Bill of sale. For asset purchase transactions, the bill of sale formally transfers title to each specific asset included in the transaction. The bill of sale should list every asset separately — not "all assets used in the business" but specifically enumerated items cross-referenced to the asset schedule in the APA.
- Assignment and assumption agreement. Transfers the seller's rights and obligations under customer and supplier contracts to the buyer. For each contract that requires third-party consent to assign, a separate consent document from the counterparty is required at or before closing.
Closing day logistics matter. Failed closings due to wire transfer issues, missing documents, or last-minute disputes are more common than they should be. Have every document reviewed and signed by counsel before closing day. Fund escrow 24 hours early. Confirm the funds flow memo with all parties the day before. The closing table should be confirmation of decisions already made — not the place to resolve outstanding issues.
The Toolkit Is the Training
Every document in this guide is something a practising business broker or M&A advisor works with on live transactions. The Career Strategy Session maps your background to the specific deal types where you already have the sector knowledge to use these tools competently from day one — and identifies exactly which skills and credentials need to be built before your first client engagement.

At minimum: signed listing agreement or engagement letter (including fee structure, tail period, and carve-out list); signed NDAs from every qualified buyer before receiving marketing materials; a Confidential Information Memorandum or broker profile presenting the business; an offer-to-purchase or LOI template; a due diligence checklist; and a secure document repository for due diligence. For LMM advisory engagements: additional documents include an anonymous teaser, IOI forms, process letters, buyer tracking log, management presentation, and controlled auction procedures.
A tail period is the time after an engagement expires or terminates during which the broker is still entitled to a success fee if the seller transacts with a buyer the broker introduced. Typical tail periods: 12–18 months for main street brokerage, 18–24 months for LMM advisory. The tail clause must be paired with a carve-out list — a schedule of named buyers the seller identified independently before the engagement began, who are excluded from the tail. The carve-out list must be agreed and attached before signing — post-execution additions should not be accepted by the advisor.
An APA (Asset Purchase Agreement) transfers specific business assets — equipment, inventory, contracts, IP, goodwill — while the buyer chooses which liabilities to assume. Unknown liabilities remain with the selling entity. An SPA (Stock or Membership Interest Purchase Agreement) transfers the entire legal entity — all assets AND all liabilities, including unknown ones. APAs are more common for small businesses because they protect buyers from undisclosed liabilities. SPAs are more common for larger businesses, C-corporations, and deals where contracts are non-assignable. Tax treatment differs: APAs give buyers a step-up in asset basis; SPAs generally produce better tax outcomes for sellers through capital gains treatment.
A comprehensive checklist covers seven categories: Financial records (3 years tax returns, monthly P&Ls, bank statements, AR/AP aging, debt schedule); Legal and corporate (licences, litigation history, UCC searches, insurance); Real estate (lease agreements, landlord estoppel, property condition); Employees and HR (roster with compensation, employment agreements, benefits, workers' comp history); Customers and contracts (top customer list, contract assignability, retention data); Operations and equipment (asset register, vehicle titles, technology systems, SOPs); and Intellectual property (trademark registrations, domain ownership, software IP). The above Stage 6 checklist covers all categories in expandable detail.
A CIM (Confidential Information Memorandum) is the primary marketing document for a business sale, provided only to NDA-signed prospective buyers. It contains: executive summary, company overview, financial statements (normalised with EBITDA bridge), management team profiles, market and competitive analysis, investment highlights, transaction overview, and process letter. LMM CIMs run 30–80 pages. Main street broker profiles are the simpler equivalent — 5–15 pages with similar content at lower institutional depth. The quality and defensibility of the CIM's financial presentation directly affects the valuation offers received — see the CIM writing guide →
