The diligence questions a buyer will ask, scored honestly, and what each unresolved item costs you at the table.

Sale readiness is whether your business can survive a buyer's diligence without the price moving. Most deals that fall apart do not fail on valuation; they fail because something surfaced in diligence that the seller had not addressed, and the discovery costs more credibility than the issue itself was worth. Readiness is therefore about eliminating surprises, not about maximising a headline number.
Financial records come first, because everything else is checked against them. Then customer quality, owner dependence, staff and contracts, legal and compliance, and finally the operational documentation that tells a buyer whether the business can run without its current owner. A weakness in any one of them reduces either the price or the certainty of completion.
Score yourself before a buyer does. Anything you cannot evidence today is something you will be arguing about under time pressure later.
| Area | What a buyer tests | Cost of a gap |
|---|---|---|
| Financial records | Accounts reconcile to filed returns | Add-backs rejected, multiple cut |
| Customer base | Concentration, contracts, churn history | Discount or an earn-out you must earn |
| Owner dependence | Whether the business runs without you | Largest single reduction in multiple |
| Staff and contracts | Key people under contract, no gaps | Retention payments taken from your proceeds |
| Legal and compliance | Licences, leases, disputes, IP ownership | Escrow held back, or the deal stalls |
| Documentation | Processes recorded, not in heads | Longer transition, lower certainty |
A buyer's adviser reconciles your normalised earnings to your filed returns line by line. Any add-back you cannot document from the accounts is removed, and each removal comes off the earnings that the multiple applies to. On a 3.5x multiple, a $40,000 add-back you cannot evidence costs $140,000 of price.
The IRS requires businesses to keep records supporting the income and deductions reported on their returns, so the standard is one you should already meet. In practice the gap is usually not missing records but unreconciled ones, where management figures and filed figures drifted apart over several years.
What three unresolved items cost at the table (2026)
Asking price basis
Normalised earnings claimed $348,000
Multiple sought 3.5x
Asking price $1,218,000
Diligence findings
Add-backs without documentation -$40,000
Revised earnings $308,000
Largest customer at 38% of revenue
-> multiple reduced to 3.1x
Owner holds all key relationships
-> 20% of price moved to earn-out
Revised structure
308,000 x 3.1 $954,800
Paid at completion (80%) $763,840
Contingent on earn-out $190,960
Gap to asking price at completion -$454,160
None of the three findings were new information.Every one of those items was knowable a year earlier and fixable in that time. The cost of discovering them during diligence rather than before it was roughly 37% of the price at completion.
Go through the six areas and mark each one ready, fixable within a year, or structural. Structural items, such as revenue that genuinely cannot be made recurring, are things you price in rather than fix. Fixable items are the argument for waiting, and the arithmetic above shows what waiting is worth.
One more consideration: sale readiness overlaps almost entirely with well-run. Businesses that are documented, diversified and independent of their owner are easier to operate and more resilient whether or not you ever sell, which makes this work worth doing even if the exit is years away or never happens.
