The Broker's Guide to Buying A Book Of Business Insurance Agency

Buying a book of business from an insurance agency is not like buying a building or a piece of equipment. What you are purchasing is the agency's right to service existing clients - not the clients themselves. Clients can leave the day after closing. That single fact changes everything about how to structure, price, and close the deal.

This guide covers what you actually acquire, how deals are structured, what valuation looks like, the full due diligence checklist, financing options, and what happens to carrier appointments after you close.

Key Takeaways

• P&C books of business sell for 1.5x to 2.5x trailing twelve-month revenue. Life and health books trade at different multiples.
• You are buying the right to service the clients - not a contractual relationship. Client retention post-close depends on how well you execute the transition.
• SBA 7(a) loans are the most common financing vehicle for book-of-business acquisitions up to $5 million.
• Most standard market carriers require notification of an ownership change and many require prior approval before the transaction closes.
• The single most important due diligence item is the prior three years of client retention data. A book with 75% retention is worth less than half of a book with 92% retention at the same revenue multiple.
• Earn-out provisions protect the buyer if retention drops post-close. Negotiate them into every deal.

What You Are Actually Buying

When you buy a book of business, you acquire three things: the agency's client files and contact information, the agency's carrier appointments, and the agency's staff relationships. None of these is legally binding on the clients.

An insurance client is not obligated to stay with a new owner. They will stay if the service continues, the relationship transfers well, and no one disrupts their coverage. They will leave if the new owner fumbles the first renewal, if the seller bad-mouths the transition, or if a competitor reaches them with a better offer during the ownership change.

This is why retention data matters more than revenue. A book generating $600,000 in revenue with 80% annual retention will lose $120,000 in business in year one. A book generating $500,000 with 94% retention will lose $30,000. The second book is worth more in practice even if the revenue multiple looks lower on paper.

You are also buying carrier relationships. If the seller has Travelers, Chubb, or Hartford appointments, those appointments transfer or terminate based on each carrier's contract and state-specific rules. Get copies of every carrier appointment letter before signing a letter of intent.

How Book-of-Business Deals Are Structured

Asset Purchase vs. Stock Purchase

Most book-of-business transactions are structured as asset purchases. The buyer acquires specific assets - the client list, files, goodwill, phone numbers, and trade name - rather than acquiring the legal entity. Asset purchases are cleaner for the buyer because they do not inherit undisclosed liabilities from the selling entity.

Stock purchases acquire the selling corporation or LLC itself. They are more common when the seller needs specific tax treatment, when carrier appointments cannot transfer easily, or when the selling entity has contracts that do not survive an asset sale. Stock purchases require deeper entity-level due diligence including tax filings, litigation history, and shareholder agreements.

Earn-Out Provisions

An earn-out ties a portion of the purchase price to client retention over 12 to 24 months post-close. A typical structure: 70% of the purchase price at closing, 30% payable 12 months later based on actual retention against a benchmark.

Example: The seller's book generates $400,000 in revenue. The agreed multiple is 2.0x, so the total price is $800,000. The closing payment is $560,000 (70%). The earn-out of $240,000 pays in full if retention is 90% or above at month 12. It scales down proportionally if retention falls below 90%.

Earn-outs protect the buyer if the seller exaggerates retention or if the book deteriorates faster than expected after the announcement. Sellers dislike earn-outs, but a seller confident in their retention data should accept them.

Valuation: What the Market Pays

P&C books of business trade at 1.5x to 2.5x trailing twelve-month revenue in most markets. Several factors push a book toward the top or bottom of that range.

Life insurance books use a different multiple framework based on recurring premium and policy type. Benefits books (group health, dental, voluntary) trade on a separate multiple based on member count and employer size. This guide focuses on P&C.

The Due Diligence Checklist

Work through this checklist before signing a purchase agreement. Do not skip items because the seller seems trustworthy.

Carrier and Appointments

• Copy of every carrier appointment letter currently active
• Written confirmation from each carrier about their ownership-change policy
• List of carriers where binding authority exists and the specific limits
• Any carrier warning letters or probationary notices in the past 3 years
• Markets that require reappointment vs. markets that allow assignment of the appointment

Client and Revenue

• Expiring policy schedule (every active policy with premium, carrier, expiration date)
• Client concentration analysis - what percentage of revenue comes from the top 10 accounts
• Retention rate for each of the past 3 policy years, by line of business
• Lost account log for the past 3 years with reason codes
• Renewal schedule for the next 12 months - identify accounts expiring in the first 90 days post-close

E&O and Claims

• E&O (errors and omissions) loss runs for the past 5 years
• Current E&O carrier and premium
• Any pending E&O claims or open coverage disputes
• Any state insurance department complaints filed against the agency in the past 5 years
• Prior acts coverage confirmation - who covers E&O for work done before the sale

Operations and Staff

• Complete staff list with tenure, role, compensation, and intent to stay post-close
• Agency management system (AMS) and software licenses - what transfers, what must be re-licensed
• Lease agreements for office space and equipment
• Any non-solicitation or non-compete agreements binding current staff

Legal and Financial

• Three years of agency financial statements (P&L and balance sheet)
• Tax returns for the past 3 years
• Corporate entity documents (articles of incorporation, operating agreement)
• Outstanding loans, lines of credit, or encumbrances on agency assets
• Any litigation, pending or settled, in the past 5 years

Seller Obligations

• Non-compete agreement (minimum 3-year term covering the agency's market area)
• Non-solicitation agreement covering staff and clients
• Transition assistance commitment - minimum 90 days of seller involvement post-close
• Written client introduction letter cosigned by seller

Financing Options

SBA 7(a) Loans

SBA 7(a) loans are the most common financing vehicle for insurance agency acquisitions up to $5 million. The SBA does not lend directly - it guarantees loans made by approved lenders such as Live Oak Bank, which specializes in professional services acquisitions including insurance agencies. Key terms: loan amounts up to $5 million, repayment terms up to 10 years for goodwill, interest rates at prime + 2.75% or lower, 10% to 20% buyer equity injection required. SBA-approved lenders who understand insurance agency valuations are critical. A general business bank will not understand why a book of business is worth 2x revenue.

Seller Financing

Sellers who cannot find a full cash buyer often carry 20% to 40% of the purchase price as a seller note. The note is subordinate to SBA financing, typically at 4% to 6% interest, with a 3 to 7 year term. Seller financing aligns incentives - the seller wants retention to stay high so the buyer can service the debt.

Agency Aggregators and Roll-Ups

Some buyers are backed by private equity-affiliated aggregators (Patriot Growth Insurance Services, Acrisure, or similar platforms). These buyers typically pay at the higher end of multiples (2.0x to 3.0x) because they are acquiring scale. If you are selling to an aggregator, understand that the cultural integration will be different from a seller-to-independent-owner transaction.

Carrier Consent: What Happens to Appointments After Acquisition

Most standard market carriers - including Travelers, Hartford, and Nationwide - require written notification of an ownership change before it occurs. Many also require prior written approval. Review every carrier appointment contract for the ownership-change clause before signing a purchase agreement.

Outcomes vary by carrier:

• Automatic assignment: The appointment transfers automatically upon notification. Common with smaller regional carriers.
• Prior approval required: The carrier reviews the new owner's qualifications before consenting. If the new owner does not meet the carrier's criteria, the appointment terminates. This is the most common outcome with standard market carriers.
• Reappointment required: The carrier terminates the existing appointment and requires the new owner to apply for a new appointment under their own entity. There may be a gap in binding authority during the reappointment process.

Do not close a book-of-business acquisition without written carrier consent or confirmation of the consent process. Losing a major carrier appointment post-close can eliminate 20% to 40% of the book's value within 90 days.

Integration Plan: The 90 Days That Determine Retention

The transition period is where acquisitions succeed or fail. A client who has not heard from the new owner 60 days after closing is looking for other options.

Week 1 post-close: Send cosigned introduction letter from both seller and buyer to every client. The letter should be personal, reference the history of the relationship, and give the client a direct phone number and email for their new contact.

Week 2-4: Call every top 20 account individually. The seller should introduce the buyer on a three-way call wherever possible. These accounts represent the bulk of the book's revenue - do not rely on mail to retain them.

Month 1-3: Migrate every client file into your AMS. Audit every expiring policy in the next 90 days. Contact clients 60 days before expiration to confirm coverage needs and relationship status.

Month 3-6: Complete a full staff transition review. Identify producers or CSRs who are ambivalent about staying and address compensation and role questions directly. Talent loss at the agency level drives client attrition.

Frequently Asked Questions

What is a fair price for buying a book of business from an insurance agency?

P&C books of business trade at 1.5x to 2.5x trailing twelve-month revenue in most US markets. The multiple reflects retention history, client concentration, line of business mix, and whether carrier appointments transfer cleanly. A book with three consecutive years of 90%+ retention and no concentrated accounts justifies 2.0x to 2.5x. A book with declining retention or concentrated commercial accounts trades closer to 1.5x.

What is the difference between buying a book of business and buying an insurance agency?

Buying a book of business typically means an asset purchase - you acquire the client list, carrier relationships, and agency goodwill. Buying an insurance agency as an entity (stock purchase) means you acquire the legal entity including all its liabilities. Most buyers prefer asset purchases because they do not inherit unknown liabilities from the selling entity.

Do carrier appointments transfer when you buy a book of business?

Not automatically. Most standard market carriers require prior notification and written approval of ownership changes. Some carriers require full reappointment under the new owner's entity. Review every carrier appointment contract before closing. Losing a key market appointment post-close is one of the most common reasons acquisitions underperform their projected returns.

Can you use an SBA loan to buy an insurance agency book of business?

Yes. SBA 7(a) loans are widely used for insurance agency acquisitions up to $5 million. Live Oak Bank is the largest SBA lender for professional services acquisitions and understands insurance agency valuations. SBA loans require 10% to 20% equity injection from the buyer and have repayment terms of up to 10 years for goodwill-based acquisitions.

What should be in the due diligence checklist for a book-of-business acquisition?

The five critical items: (1) three years of E&O loss runs, (2) three years of client retention data by line of business, (3) expiring policy schedule for the next 12 months, (4) all carrier appointment letters with ownership-change provisions, and (5) client concentration analysis showing what percentage of revenue comes from the top 10 accounts. These five items tell you whether the book is worth the asking multiple before you spend money on legal and accounting due diligence.

What is an earn-out provision in a book-of-business sale?

An earn-out ties a portion of the purchase price to actual client retention after closing. A typical structure pays 70% of the price at closing and holds 30% for 12 months, releasing that amount based on the percentage of revenue retained. If the agreed benchmark is 90% retention and actual retention is 85%, the earn-out payment reduces proportionally. Earn-outs protect buyers from overpaying for a book that deteriorates faster than the seller's historical data suggested.
