Commercial due diligence is the disciplined process of testing whether a target business can really perform as the seller claims, and it is central to any Australian acquisition where valuation depends on future earnings, customer retention, market position, and competitive resilience. For a valuer, commercial due diligence is not a legal formality or a transaction box to tick. It is an evidence-based input into a valuation engagement that can materially change maintainable earnings, growth forecasts, discount rates, and ultimately the value concluded for a privately held business.<\/p>\n
In an acquisition setting, commercial due diligence examines the market the business operates in, the quality and durability of its customer base, and the strength of its competition. From a business valuation perspective, these are not abstract questions. They go directly to forecast reliability, risk, and the sustainability of cash flows.<\/p>\n
A valuation engagement under APES 225 requires the valuer to apply appropriate judgement, consider the purpose of the valuation, and use evidence that is relevant and supportable. Commercial due diligence provides much of that evidence. It helps determine whether a target\u2019s historical earnings are repeatable, whether growth is achievable, and whether the business has defensive characteristics that support a higher multiple or a lower discount rate.<\/p>\n
For Australian buyers, especially in private markets where information asymmetry is common, a robust commercial review can prevent overpayment. For sellers, it can identify the strengths that justify value and the weaknesses that should be addressed before a sale process begins.<\/p>\n
Many privately held businesses are marketed on the basis of headline revenue, EBITDA, or profit growth. Those figures can be misleading unless they are tested for sustainability. Commercial due diligence asks the questions that matter to valuation: Is revenue concentrated in a few customers? Are contracts recurring or one-off? Is growth being driven by price increases, volume, or a temporary market spike? How much of the earnings base depends on the owner personally?<\/p>\n
These questions affect maintainable earnings, which is the foundation of most private business valuation methodologies. If customer churn is rising, the earnings stream may be less durable than the financial statements suggest. If a business has strong net revenue retention (NRR) above 110 per cent in a subscription environment, it may justify a stronger revenue multiple than a business with flat or declining renewals. If growth is reliant on one sector or one major client, concentration risk may require a discount or a more conservative forecast.<\/p>\n
In practical terms, commercial diligence helps the valuer assess whether to rely more heavily on a capitalised earnings method, a DCF analysis, or a market multiple approach. It also informs whether a control premium, minority discount, or discount for lack of marketability should be considered in the valuation engagement.<\/p>\n
The first layer of commercial diligence is the market itself. A business may have sound historical earnings, but if its addressable market is shrinking or heavily fragmented, the valuation outcome should reflect that reality. Conversely, a business in a structurally growing sector with barriers to entry may attract a higher valuation multiple, particularly where the growth is supported by credible market data rather than management aspiration.<\/p>\n
For Australian businesses, market analysis should consider the relevant industry benchmark, the broader economic backdrop, and the competitive intensity in the sector. In professional services and recurring revenue models, buyers will often examine the relationship between growth and retention. In manufacturing or distribution, margins and working capital intensity are often more important. In software and SaaS businesses, NRR, churn, gross margin, and customer acquisition efficiency are critical valuation drivers.<\/p>\n
Typical private market valuation markers vary by sector. Stable, mature services businesses may trade on EBIT or EBITDA multiples in the mid single digits, while higher quality recurring revenue businesses can attract materially higher revenue or EBITDA multiples where retention is strong and growth is predictable. In practice, the range depends on earnings quality, customer concentration, scale, and the level of dependence on key people. Commercial diligence gives the valuer evidence to position the business within that range.<\/p>\n
A business is only as valuable as the cash flows it can sustain. Customer diligence helps test whether those cash flows are dependable. This includes examining customer concentration, churn, contract length, renewal history, switching costs, and the proportion of revenue derived from new versus repeat business.<\/p>\n
Where a target has a small number of key customers, the valuation impact can be significant. A loss of one account may reduce maintainable earnings, extend the payback period, and increase downside risk. If customer relationships are personal to the founder rather than institutional, the underlying goodwill may be less transferable. That can reduce the value supported under an EBITDA multiple, particularly where a buyer is considering a limited scope valuation engagement and wants a narrower evidentiary basis.<\/p>\n
Working capital also matters. A business with strong headline earnings but long receivable cycles, high inventory requirements, or deferred revenue obligations may generate less free cash flow than expected. A commercial due diligence review should therefore be read alongside normalisation adjustments, working capital analysis, and any earn-out structure proposed in the transaction.<\/p>\n
For subscription, maintenance, or service contract businesses, investors pay close attention to retention and cohort behaviour. An NRR below 100 per cent signals contraction in the installed base, which usually weakens valuation support. Strong retention, low churn, and a demonstrable cross-sell history can justify a premium, especially where forecast uplift is backed by actual customer behaviour rather than optimistic budgets.<\/p>\n
In these businesses, a valuer will often test whether revenue multiples are supported by margins, growth durability, and scaling economics. A high-growth but low-retention business may not deserve the same multiple as a slower-growing, stickier competitor with superior lifetime value metrics.<\/p>\n
Competition is another core valuation input. A business operating in a crowded market with limited differentiation may be forced to compete on price, compressing margins and weakening long-term earnings power. By contrast, a business with proprietary capability, regulatory approvals, strong brand equity, or high switching costs may be able to defend margins and sustain value.<\/p>\n
Commercial due diligence should assess competitor behaviour, substitute products, cost structures, and any structural advantages the target enjoys. The question is not simply who the competitors are, but whether they can erode the target\u2019s share, margins, or customer loyalty. This is especially relevant in Australia where many private businesses serve concentrated niches and can be vulnerable to a larger entrant or a new digital competitor.<\/p>\n
For a valuation engagement, competitive position informs the forecast period, terminal value assumptions, and the risk premium embedded in the discount rate or WACC. A business with little pricing power or fragile differentiation usually warrants a more conservative cap rate or lower terminal growth assumption in a DCF model.<\/p>\n
The commercial review is only useful if it is translated into valuation logic. That means adjusting for earnings normalisation, customer concentration, expected churn, and realistic growth. It may also lead to the use of multiple methods, not just one. For example, a DCF can test whether management\u2019s forecast is internally consistent, while an EBITDA multiple derived from industry comparables can anchor the result to market evidence. In some cases, precedent transactions are more relevant than quoted market data, particularly for small and mid-market Australian businesses where public comparables are imperfect.<\/p>\n
A valuer may also apply discounts for lack of marketability where the shares or interests cannot be readily sold, and a discount for lack of control where the interest being valued does not confer control over distributions, strategy, or sale decisions. For private businesses, these adjustments are often material and should be justified by quality due diligence, not treated as formulaic add-ons.<\/p>\n
Where the target operates under a balance of recurring and project income, the valuer may separate the streams. Stable recurring income may attract a higher multiple than non-recurring project work. In a mixed business, commercial diligence helps determine how much of the earnings base is truly maintainable.<\/p>\n
Commercial due diligence does not occur in a vacuum. In Australia, the transaction structure and tax settings can affect what a buyer is willing to pay and how a valuer frames value. CGT implications, the small business CGT concessions, and the 15-year exemption can all influence seller expectations and buyer negotiations. Where the sale includes goodwill, active asset status is often central to the seller\u2019s after-tax outcome.<\/p>\n
GST treatment also matters, especially where the sale is intended to be a going concern. Division 7A concerns can arise where a private company has loans or unpaid present entitlements that need to be addressed before completion. These matters may not change enterprise value directly, but they can affect equity value, completion adjustments, and the effective price agreed between the parties.<\/p>\n
Australian market value guidance from the ATO is also relevant. Valuers are expected to support conclusions with evidence and reasonable assumptions. That is especially important where a business is being transferred between related parties, used in a family succession plan, or held in a structure that has tax significance.<\/p>\n
Division 296, which commenced on 1 July 2026, is another example of where valuation matters directly. It is a personal tax assessed to the individual, not the fund, and applies to realised earnings only. The final law uses indexed thresholds of $3 million and $10 million, with additional tax rates of 15 per cent on earnings attributable to a member\u2019s Total Superannuation Balance between those thresholds and 25 per cent above $10 million. For SMSFs holding business assets, business real property, or shares in a privately held company, current market valuations may be required for Division 296 purposes, including any optional cost base reset to market value at 30 June 2026. That creates a direct and practical reason for business owners to obtain a professional valuation.<\/p>\n
One of the most common mistakes is relying too heavily on seller-provided forecasts without stress testing the assumptions. Another is treating revenue growth as a proxy for quality, when in fact the growth may be low margin, heavily discounted, or operationally fragile. A third mistake is ignoring customer concentration until late in the process, when it becomes clear that a single client drives a disproportionate share of value.<\/p>\n
Buyers also often underestimate the value impact of owner dependency. If the business relies on the founder for sales, supervision, or technical delivery, commercial due diligence may reveal that the enterprise is less transferable than the financial statements suggest. In those cases, a valuer may need to apply a lower maintainable earnings base or a higher risk discount.<\/p>\n
Finally, some parties confuse transaction price with value. They are not always the same. A strategic buyer may pay more because of synergies, while a financial buyer may be more conservative. A valuation engagement should distinguish between the standalone market value of the business and any buyer-specific premium.<\/p>\n
Commercial due diligence is most valuable when it is treated as a valuation tool, not just a transaction checklist. By testing the market, customers, and competition, it gives the valuer the evidence needed to assess maintainable earnings, risk, and sustainable growth. For Australian business owners, that evidence can make the difference between an inflated headline price and a defensible business valuation grounded in reality.<\/p>\n
