Selling a bookkeeping business
Your firm sells on recurring monthly clients. Its inbox holds something else: years of small calls about how a charge should be coded, why an account would not reconcile and what the client said when asked. AI companies now pay to license a copy of records like these, and the buyers we work with name accounting outright; Mode takes accounting firms from 10 people.1,2,3
What they want
Your close checklist and the client back-and-forth
A bookkeeper's email and chat with clients is a long run of questions and answers: what was this charge, is this a loan or income, which class does this job belong to. The close checklist, your chart-of-accounts conventions and the notes left for next month are the firm's own procedures. micro1 says it wants well defined workflows that staff repeat, and month-end close is exactly that.4
The systems matter less than you might think. Buyers list QuickBooks and Xero next to email, Slack and Drive, and workpapers and SOPs are among the records they place.5,6,7
Who fits
Is my firm big enough?
The floors vary a lot by buyer. Mode takes accounting firms from 10 people, most other buyers want 20 to 30 or more, and a few state no minimum. If your bench is mostly 1099 bookkeepers, ask each buyer how it counts them, since several floors name full-time or W-2 staff. The quiz sorts this for you and introduces you to the buyers that take a firm your size.3,1,8,9,10

What stays out
Clients' books stay with the clients
A client's general ledger is the client's financial data, held on its behalf. Buyers say data held for clients and other third-party records can be left out, and you can exclude whole systems or folders. So a license is about how your firm works, not the numbers it has processed. Get each buyer's exclusions in writing before you send a sample.11,8,12
On money, Pewter says a 60-person accounting firm was paid $350,000 and lists an accounting group at $280K; it names no buyer, and no bookkeeping deal has been published. Most buyers charge sellers nothing, and offers usually come within a few days to two weeks of intake.13,14,15,16,17
To get ready, write down your month-end close steps as your team actually runs them, collect the chart-of-accounts conventions you reuse across clients, and pull a handful of coding questions with the client's name and figures removed. That short pack shows a buyer the firm's method without a single ledger leaving your hands.
