Buyers price a private company on accrual-basis earnings they can verify, and they discount whatever they cannot. Getting financials sale-ready means converting cash-basis books to accrual, closing the books on a monthly rhythm, and cleaning up revenue recognition, cutoffs, and inventory costing before a buyer's diligence team finds the problems for you. Owners who start this work twelve to twenty-four months ahead of a process defend their EBITDA number. Owners who start after the letter of intent usually negotiate from behind.
None of this requires a corporate accounting department. It requires a deliberate cleanup, normally done with your CPA, aimed at one outcome: statements a stranger can rely on without taking your word for anything.
Why the basis of your books matters to a buyer
Many private companies keep cash-basis books because they are simple and track the tax return. Under the cash method, as IRS Publication 538 describes it, you report income in the year you receive it and deduct expenses in the year you pay them. Accrual accounting reports income when it is earned and expenses when they are incurred, whether or not cash has moved yet.
Cash-basis statements answer one question: what hit the bank account this month? They do not answer the question a buyer is asking, which is what the business actually earned each period. A December that collects three large receivables looks like a banner month on a cash basis even if the work was done in September. Buyers, their lenders, and their accountants all think in accrual terms, and a quality of earnings (QoE) analysis will convert your numbers whether you have done the work or not. Controlling that conversion yourself is far better than watching someone else do it under deal pressure.
What a cash-to-accrual conversion involves
- Accounts receivable: revenue is recognized when earned, not when the check clears.
- Accounts payable and accrued expenses: vendor invoices, payroll earned but unpaid, and commissions land in the period they belong to.
- Deferred revenue: customer deposits and prepayments sit as a liability until the work is delivered. This one surprises owners, because cash books treat a prepayment as income the day it arrives.
- Prepaid expenses: insurance or software paid annually gets spread across the months it covers.
- Inventory: purchases become cost of goods sold when the product ships, not when the supplier gets paid.
A concrete example. A contractor collects a $300,000 customer deposit in December for work scheduled the following spring. On cash books, December profit jumps by $300,000. On accrual books it is a liability, and a buyer will treat it as one, often as a debt-like item that reduces the purchase price dollar for dollar at closing.
Your tax return can usually stay on the cash method
Converting your books to accrual does not by itself change your tax filing. Under the gross receipts test of section 448(c), for taxable years beginning in 2026 a corporation or partnership can generally still use the cash method for tax if its average annual gross receipts for the prior three years do not exceed $32,000,000 (per Rev. Proc. 2025-32; the figure adjusts for inflation each year). Many well-run companies keep accrual books for management and buyers while filing on the cash method. When a tax accounting method change is on the table, it generally requires filing Form 3115 with the IRS, which is a project for your CPA rather than a do-it-yourself exercise.
Monthly close discipline
A monthly close is a fixed routine, ideally finished within ten to fifteen business days of month-end: reconcile every bank and credit card account, book payroll and other accruals, recognize the revenue actually earned, review receivable and payable agings, record depreciation, then lock the period so prior months stop moving.
Buyers care because diligence runs on monthly data. A QoE team will request monthly income statements and balance sheets going back about three years and will test whether the trailing-twelve-month figures hold up. If the books are only trued up once a year at tax time, the monthly numbers are noise, seasonality is invisible, and every question takes a week to answer. BDO's guidance on preparing a business for sale puts the ability to provide timely monthly financial statements, along with current receivable and payable records, among the basics buyers expect to see. Locked periods matter just as much. When last year's numbers shift every time someone posts a stray entry, buyers stop trusting all of them.
Revenue recognition and cutoffs
Revenue recognition is where diligence teams find the expensive problems. US GAAP (ASC 606) recognizes revenue through a five-step model: identify the contract, identify the performance obligations in it, determine the transaction price, allocate that price to the obligations, and recognize revenue when or as each obligation is satisfied. You need a written revenue policy that is sensible for your industry and applied the same way every month.
Three situations deserve attention before a sale:
- Prepayments and subscriptions: annual contracts billed upfront must be spread over the service period rather than booked on the invoice date.
- Milestone and project work: contractors and project businesses need work-in-progress schedules that tie recognized revenue to actual progress.
- Cutoff: revenue belongs in the period it was earned. A shipment that leaves the dock on January 3 does not belong in December, whatever the year-end incentive plan says. Diligence teams routinely test the days on either side of period-end for exactly this.
Sloppy cutoffs are corrosive even when they wash out over a full year, because they distort the monthly trend a buyer uses to judge momentum. They also invite the suspicion that other numbers were managed too.
Inventory costing
For manufacturers, distributors, and e-commerce companies, inventory is where book profit hides. Sale-ready inventory accounting looks like this:
- Regular physical counts reconciled to the ledger, whether cycle counts or at minimum a hard year-end count.
- A consistent costing method (FIFO, weighted average, or standard costs with variances reviewed) so gross margin is comparable period to period.
- An obsolescence reserve that honestly writes down dead stock instead of carrying it at cost forever.
- Freight-in and, where appropriate, direct labor and overhead captured in inventory so cost of goods sold reflects the true cost.
For tax purposes, Publication 538 permits small business taxpayers meeting the same gross receipts test to simplify inventory accounting, for example by treating inventory as non-incidental materials and supplies or by following the treatment in their books and records. Keeping tax simple is fine. The books a buyer sees still need real costing, because gross margin by month and by product line is one of the first analyses a diligence team builds.
Chart-of-accounts cleanup
The chart of accounts is the skeleton of your reporting, and a messy one makes even accurate books hard to trust. A sale-ready chart separates revenue by line of business, keeps cost of goods sold distinct from operating expense so gross margin is real, and gives owner-related items (owner salary, vehicles, family members on payroll, related-party rent) their own clearly labeled accounts so future add-backs are traceable to the ledger instead of to memory. Shrink the miscellaneous and suspense accounts to near zero. A dollar in a clearly labeled account is a dollar nobody argues about; a dollar in miscellaneous is a dollar the buyer discounts.
When reviewed or audited statements are worth it
CPA firms offer three levels of service on financial statements, and the AICPA draws the lines clearly.
| Engagement | Assurance | What the CPA does | Typical role in a sale |
|---|---|---|---|
| Compilation | None | Assembles management's numbers into statement form; independence not required | Baseline formality at modest cost; adds little diligence weight |
| Review | Limited | Inquiry and analytical procedures by an independent CPA to identify material misstatement | Common credibility step for lower-middle-market sellers |
| Audit | High (not absolute) | Understands internal controls, tests and independently verifies balances, issues an opinion | Larger deals, institutional buyers, lender requirements |
The AICPA notes that audits are typically appropriate, and often required, for complex financing such as seeking outside investors, selling a business, or considering a merger. In practice the answer scales with deal size and buyer type. Smaller deals frequently close on well-kept internal statements plus a QoE report. As deal size grows and institutional buyers or their lenders enter, a review, and eventually an audit, starts paying for itself in credibility and speed. Two timing notes: a first-year audit takes meaningfully longer than a repeat one, so a planned audit should start a year or two before a process, and a QoE report serves a different purpose than an audit (normalized earnings versus assurance on the statements), so one does not replace the other.
How clean books change diligence and price
Every open question in diligence has an asymmetric cost, because buyers resolve uncertainty in their own favor. BDO's sale-preparation guidance is blunt on this point: perceived inadequacies in the financials result in discounts applied to projected cash flows, and a buyer may be skeptical when a large portion of EBITDA comes from adjustments. Clean accrual books attack both problems at once. They shrink the add-back schedule, because personal and one-time items are already isolated, and they let the buyer's accountants verify the earnings quickly instead of reconstructing them.
The practical effects show up in four places. Diligence gets shorter, because requests are answered from the ledger in days instead of weeks. Re-trades get rarer, because there is less undiscovered bad news for a buyer to price late in the process. The working capital peg negotiation goes better, because it is set from reliable monthly balance sheets rather than the buyer's conservative guess. And the earnings number itself holds, which matters more than anything else: on a business valued at a multiple of EBITDA, every dollar of earnings that survives diligence is worth several dollars of price. Sell-side platforms such as Bankerly.ai build the quality of earnings analysis directly from these records; whoever runs your process, clean monthly accrual books are the raw material it works from.
The work is unglamorous. It is also among the highest-return preparation an owner can do, and your CPA is the natural partner for it. Start early enough that the buyer's team finds order instead of questions.

Frequently asked questions
- Should my books be on a cash or accrual basis before selling my business?
- Buyers, lenders, and quality of earnings teams evaluate companies on accrual-basis numbers, because accrual matches revenue and expenses to the periods they were earned and incurred. If your books are cash basis, plan a conversion with your CPA well before going to market. Your tax return can often remain on the cash method, since converting the books does not by itself change your tax filing.
- What is the difference between reviewed and audited financial statements?
- A review provides limited assurance: an independent CPA performs inquiry and analytical procedures to identify material misstatement. An audit provides high (though not absolute) assurance: the CPA also evaluates internal controls, tests balances, and independently verifies items before issuing an opinion. Audits cost more and take longer. The right level depends on deal size, buyer expectations, and any lender requirements.
- Do I need audited financials to sell my business?
- Often no. Many lower-middle-market deals close on well-kept internal statements supported by a quality of earnings report. That said, the AICPA notes audits are often required for complex financing, outside investors, or a sale or merger, and institutional buyers and their lenders are the usual source of that requirement. Ask early what your likely buyer pool expects, and remember first-year audits take longer.
- How many years of financial statements do buyers want to see?
- Most diligence requests cover roughly the last three full fiscal years plus monthly statements and a trailing-twelve-month view through the most recent close. Buyers also expect supporting detail: revenue by customer, receivable and payable agings, payroll records, and tax returns that reconcile to the books. The further back your monthly records are reliable, the faster diligence moves.
- How do you convert cash basis books to accrual?
- The core steps: record accounts receivable so revenue lands when earned, record accounts payable and accrued expenses when incurred, move customer prepayments into deferred revenue, spread prepaid costs over the periods they cover, and run inventory through cost of goods sold when items sell. Most owners do this with their CPA and restate two to three prior years so trends stay comparable.
