Buy-sell agreement valuation updates: what to refresh and which assets get missed

What a buy-sell valuation update does

A buy-sell agreement valuation update resets the price at which the remaining owners, or the company, would buy an owner's interest when a trigger event occurs: death, disability, retirement, termination, divorce or a voluntary exit. The agreement itself sets how the price is refreshed, and the most common failure is neglect: a stated value signed years ago that no longer reflects the business.

For a CPA firm, the update is a natural annual touchpoint. You already hold the financial statements and tax returns, you may have prepared the last valuation, and the owners expect you to raise anything that has changed. One item that rarely shows up in the number is the company's archive of operational records, which may be licensable to AI developers but has no income history to value.

How agreements set the price

Each pricing mechanism has its own update routine and its own blind spots.

How often to update the valuation

Update on the schedule the agreement sets, and again whenever something material changes. Where the agreement is silent, an annual review tied to year-end close and the tax return cycle is a practical habit.

Events that justify an out-of-cycle review:

• A new owner joins, an owner's percentage changes or an owner signals retirement.
• A large customer is won or lost, or a business line is added or sold.
• An acquisition, refinancing or recapitalization.
• A review of the life or disability insurance that funds the purchase obligation.
• A new asset or revenue source appears that the current method does not capture.

Timing matters more as owners age. McKinsey's February 2026 report on the great ownership transfer estimates that about six million US small and medium-size businesses will face ownership transitions by 2035 as baby boomers retire, and that more than half of US small-business owners are over 55. For many clients, the trigger events in the agreement are no longer hypothetical.

An update process for the engagement team

1. Pull the signed agreement, every amendment and the last certificate or appraisal, and note the valuation date and standard of value it uses.
2. Refresh the financial inputs: normalized earnings, owner compensation adjustments, working capital and debt.
3. Recalculate any formula and test it against a market-based cross-check so the owners see any gap.
4. Run an intangible asset review with the owners: customer relationships, contracts, trade names, software, the assembled workforce and operational records.
5. Record any asset the method does not capture in a memo to the owners, with a plain statement of why it is not in the number.
6. Have the owners sign the new certificate, or engage the appraiser, and align insurance funding with the new value.
7. Set the next review date and list the events that would bring it forward.

Why operational records are often an unvalued asset

Years of support tickets, deal histories with outcomes, project files, engineering records, SOPs and internal communications are a by-product of running the business. They do not sit on the balance sheet, and an income-based valuation built on historical earnings will not reflect them because they have never produced income. A cost approach misses them too, since nobody set out to create them.

The demand behind them is recent. AI developers training agents to carry out real work want permissioned records of multi-step workflows and their outcomes, and that material exists mostly inside companies. Not every archive qualifies: the company needs several years of history across many systems, the rights to license the material and an owner willing to consider an exclusive license for an agreed term.

The honest treatment in a buy-sell update is to describe the asset and leave it out of the number unless the owners have a market indication. A guessed figure invites a dispute at the moment the agreement exists to prevent one.

How to get a market read instead of guessing

With the owners' permission, an introduction to SourceX can show whether the records are licensable and what form a deal could take.

1. The owners agree to explore it; you pass on basic fit information only, never records.
2. SourceX screens size (50+ full-time employees at peak, contractors excluded), operating history, data breadth and rights with an authorized sponsor.
3. The company completes a data inventory of its systems and years of history.
4. SourceX and the company agree one all-in price and the terms before any buyer sees the opportunity; the company keeps ownership and licenses rather than sells.
5. The owners can stop at any point, because nothing binds the company until it signs.

Read the buy-sell agreement before a license is signed. Some shareholder or buy-sell agreements require every owner to approve material contracts, and an exclusive license for an agreed term should be visible to everyone bound by the price mechanism. The company fit checker offers a quick, non-binding first screen, and who qualifies sets out the baseline.

Independence and referral-fee rules for CPA firms

Keep the referral question separate from the valuation engagement. Under the AICPA's Commissions and Referral Fees Rule (ET 1.520.001), a member in public practice may not accept a commission for recommending a product or service to a client when the member or firm also performs an audit, a review, certain compilations or an examination of prospective financial information for that client, and permitted referral fees must be disclosed to the client (AICPA Code of Professional Conduct). State rules can be stricter than the AICPA Code; the New Jersey Society of CPAs' resource on commissions and contingent fees shows one state's differences. Confirm your state rule and your firm's policy before you register.

Partners earn 25% of the eligible platform fees SourceX actually collects from the referred company's licensing deals, capped at $100,000 per referred company, and rewards become payable only after the buyer pays and SourceX receives its fee. The reward is a share of SourceX's fee and is never deducted from what the company receives. The accountants partner page covers fit and conflicts for firms like yours.

This is general information, not legal, tax or financial advice. Confirm with your own counsel, tax adviser or professional body before acting.

Limits and open questions

• There is no settled method for valuing licensable records in a private company, and a market indication is not an appraisal.
• Demand depends on what AI labs and data buyers need at the time, and no deal or reward is guaranteed.
• Records that mainly belong to the company's clients, consumer personal data, health records without authorization or de-identification, deleted archives and data already licensed for AI training usually rule a company out.
• If a license closes, the one-time payment becomes part of the financial history the next valuation reviews.
• A planned system replacement can erase the asset; a records census, as described in the finance transformation roadmap guide, keeps it intact, and the risk register template gives archive loss a named owner.

Next step

At the next certificate signing, add one agenda line: which records the company holds and whether the owners want a market read. If they do, register as a partner and make the introduction, or let the owners apply directly at sourcex.si/apply.
