Every business owner who has been through a sale, capital raise, or even a serious lending application knows the same thing: the financial due diligence process exposed problems they did not know they had. Deals slow down, valuations drop, and sometimes transactions collapse entirely because the books tell a different story than the one the owner believed.
This is not an article about how to raise capital or sell your business. It is about what your books look like from the other side of the table, so you can fix the problems now rather than discovering them when someone is writing a cheque.
Investors and buyers care less about your total revenue number than they do about the quality of that revenue. Quality means predictability, diversification, and sustainability.
Recurring vs one-off revenue. A business doing $3 million in annual recurring contracts is valued very differently to a business doing $3 million in project-based work. Recurring revenue is worth 2 to 4 times more in a valuation because it is predictable. If your accounting does not clearly separate recurring revenue from one-off revenue, you are making it harder for a buyer to see your value.
Customer concentration. If one customer represents more than 20 per cent of your revenue, it will be flagged. If one customer represents more than 40 per cent, it will reduce your valuation or kill the deal. Buyers see customer concentration as risk: if that customer leaves, a disproportionate share of revenue disappears. Use our client concentration risk calculator to check where you stand.
Revenue recognition accuracy. This is where many SMEs trip up. If you are recognising revenue when you invoice rather than when you deliver, your P&L overstates revenue in some months and understates it in others. Buyers will restate your revenue on an accrual basis during due diligence, and the restated number is often 5 to 15 per cent different from what you have been reporting.
Channel and geography mix. Where does your revenue come from? If 80 per cent comes from one channel (say, one referral partner), that is a dependency. Buyers want to see multiple acquisition channels generating revenue independently.
After revenue quality, buyers go straight to margins. They are looking for the true cost of delivering your product or service.
Gross margin consistency. A business with 55 per cent gross margin every month is far more attractive than one that swings between 40 per cent and 65 per cent. Volatility in gross margin signals pricing problems, scope creep, or inconsistent cost management. If your gross margins are volatile, examine whether you are consistently coding direct costs to cost of goods sold versus operating expenses.
Owner adjustments. Almost every SME has expenses running through the business that benefit the owner personally. A car, a phone, travel that is partially personal, a family member on the payroll who does minimal work. Buyers will identify all of these and make "normalisation adjustments" to your EBITDA. The more adjustments they have to make, the less confidence they have in your numbers.
Subcontractor vs employee classification. If you are using subcontractors to deliver core services, a buyer will question whether those contractors should be classified as employees. If the ATO agrees with the buyer (which they often do), the business suddenly has an underpaid superannuation liability, potential payroll tax exposure, and Fair Work compliance risk. This is one of the most common deal killers for Australian SMEs. See our contractor vs employee classification checklist.
Below-market owner salary. Many SME owners pay themselves below market rate to make profits look higher. Buyers see through this immediately and will add a "market rate salary" adjustment to your expenses during normalisation. If you are paying yourself $80,000 but a replacement CEO would cost $180,000, your true EBITDA is $100,000 lower than your P&L shows. Curious what other owners pay themselves? See our analysis of what Australian business owners pay themselves.
Many SME owners focus exclusively on their P&L and barely glance at the balance sheet. Buyers do the opposite. The balance sheet tells them what the business actually owns and owes.
Working capital position. Buyers calculate net working capital (current assets minus current liabilities) and compare it to industry benchmarks. If your business needs $200,000 in working capital to operate and your balance sheet shows $80,000, the buyer knows they need to inject $120,000 on day one. That comes straight off the purchase price.
Aged receivables. Outstanding invoices over 90 days are treated as bad debt risk by buyers. If you have $150,000 in receivables and $30,000 of that is over 90 days, the buyer may discount the value of those receivables by 50 to 100 per cent. Strong credit control practices directly protect your valuation.
Leave liabilities. Accrued annual leave and long service leave are real liabilities that transfer to the buyer. If your team of 20 has accumulated $180,000 in leave liabilities because you have not been enforcing leave policies, that is $180,000 the buyer has to cover. Read our analysis of annual leave liability as a financial risk.
Unreconciled accounts. Nothing destroys buyer confidence faster than unreconciled bank accounts, suspense accounts with unexplained balances, or intercompany loans that do not balance. These signal a lack of financial control and create doubt about every other number in the accounts.
Tax liabilities. Outstanding BAS, PAYG, or superannuation obligations are identified immediately. If you owe the ATO $80,000 in unpaid super from the last two quarters, that liability transfers and the buyer adjusts their offer accordingly. Worse, it signals compliance risk and potential director penalty exposure.
Having worked with businesses preparing for due diligence, these are the issues that come up in the majority of cases.
Messy chart of accounts. Revenue lines that mix product and service income. Cost of goods sold that includes operating expenses. "Miscellaneous" or "other" expense accounts with five-figure balances. A poorly structured chart of accounts forces the buyer to restate your financials from scratch, adding weeks to the process and reducing confidence.
Inconsistent accounting policies. Switching between cash and accrual basis mid-year. Changing depreciation methods. Capitalising expenses in some periods and expensing them in others. Inconsistency makes it impossible to compare periods, which is the primary thing a buyer is trying to do.
Related party transactions without documentation. Loans to or from directors, rent paid to a related entity, management fees to a family trust. All of these are legitimate if documented and at arm's length. Without documentation, they become red flags that suggest the business is being used as a personal piggy bank.
No management accounts. Many Australian SMEs produce financial statements once a year for their tax agent. They have no monthly P&L, no cash flow reporting, and no budget to compare against. For a buyer, the absence of management accounts signals that the owner is not managing the business by the numbers, which raises questions about what else they are not monitoring.
Payroll compliance gaps. Underpayment of award rates, incorrect super calculations, or STP reporting errors. These create contingent liabilities that the buyer inherits. With the Fair Work Ombudsman increasing enforcement activity and the introduction of wage theft as a criminal offence, payroll compliance gaps are receiving more scrutiny than ever.
If you are considering selling, raising capital, or bringing in a partner within the next one to two years, here is what to prioritise.
Months 1 to 3: fix the foundation. Clean up your chart of accounts. Reconcile every bank account and clear any suspense account balances. Ensure BAS and super are current. Get your payroll audit-ready.
Months 4 to 6: build the reporting. Implement monthly management accounts including P&L, balance sheet, and cash flow. Start tracking key metrics: gross margin by service line, customer concentration, revenue by type, and working capital. Begin producing variance analysis against budget.
Months 7 to 9: normalise and document. Document all related party transactions with written agreements. Adjust owner salary to market rate (or at least document the gap). Separate personal expenses from business expenses. Prepare a normalised EBITDA schedule with clear add-backs.
Months 10 to 12: stress test. Review your financials as if you were the buyer. Look for inconsistencies between periods. Check your revenue recognition. Test your debtor collection cycle. Ensure leave liabilities are accurately accrued. Run through the common issues listed above and address anything outstanding.

The difference in valuation between a business with clean, well-documented financials and one with messy books is not marginal. It is substantial.
A business with consistent margins, clean reporting, and no surprises might achieve a 4 to 6 times EBITDA multiple. The same business with unreconciled accounts, undocumented related party transactions, and inconsistent revenue recognition might achieve 2 to 3 times, if the deal proceeds at all. On a $500,000 EBITDA, that is the difference between a $2 million and a $3 million outcome versus a $1 million to $1.5 million outcome.
The investment in getting your books right, whether that is engaging a proper finance team, cleaning up your chart of accounts, or implementing monthly reporting, typically costs $30,000 to $72,000 per year. The return in avoided valuation discount is often 10 to 50 times that amount.
How far back do buyers look at financial records?
Typically three years of financial statements and tax returns. Some buyers request up to five years for established businesses. Monthly management accounts for the trailing 12 to 24 months are increasingly expected.
Do I need audited financials to sell my business?
Not necessarily. Most SME transactions under $10 million use reviewed or compiled financial statements rather than full audits. However, buyers will conduct their own due diligence regardless.
What is normalised EBITDA?
Normalised EBITDA is your earnings before interest, tax, depreciation, and amortisation, adjusted for one-off items and owner-related expenses that would not recur under new ownership. This is the number most valuations are based on.
How long does financial due diligence take?
For a well-prepared SME, four to eight weeks. For a business with messy books, it can stretch to three to six months and sometimes kills the deal entirely.
Should I engage a CFO before selling?
If you are 12 or more months from a transaction, engaging a fractional CFO or embedded finance team to prepare your books is one of the highest-ROI investments you can make. If you are less than six months out, it may be too late to make meaningful improvements.
What happens if due diligence reveals problems?
The buyer typically adjusts the purchase price downward, adds warranty protections to the sale agreement, or walks away. In some cases, issues discovered during due diligence (particularly tax or payroll compliance gaps) can trigger ATO reporting obligations.
Can I sell my business without clean books?
You can, but you will accept a significantly lower price and the pool of potential buyers shrinks dramatically. Sophisticated buyers avoid businesses with unreliable financials because the risk is unquantifiable.
What is the most common reason deals fall through?
Financial surprises. Liabilities the seller did not disclose, revenue that looks different once restated, or compliance gaps that create contingent exposure. The cure is transparency and preparation.
Pull up your Xero file right now and check three things: do you have any unreconciled bank transactions older than 30 days, is your aged receivables report showing any balances over 90 days, and do you have a suspense account or clearing account with a balance? If any of these are true, you have work to do, whether or not a sale is on the horizon. Clean books serve you every day, not just on exit day.
