Due Diligence Before You Buy: What It Means for Your Finance Application

Acquisition Finance Guide
Updated September 2026 · Due Diligence · Business Acquisition Finance

Due diligence and business finance are not two separate stages of buying a business — they’re the same process viewed from two angles. What your accountant flags as a risk is often exactly what a lender uses to decide how much they’ll fund and on what terms. Buyers who bring their finance broker into due diligence early get a realistic funding picture before they negotiate; buyers who wait often discover the gap after they’ve already paid a deposit.

Most people buying a business in Australia treat due diligence and finance as sequential steps: first confirm the business is sound, then work out how to pay for it. That order feels logical. It’s also one of the more common reasons acquisitions stall in the weeks after a contract is signed — not because the business turned out to be a bad one, but because the buyer discovered late that a lender saw the deal differently to how they did.

This article looks at why that gap exists, what it typically involves for Australian business buyers, and how to close it before it costs you time, money or the deal itself.

In short

Nearly half of Australia’s Baby Boomer business owners plan to sell or exit within five years, but only a quarter have an actual succession plan. That gap means more businesses are coming to market without clean records, which makes due diligence — and the finance conversation attached to it — more important than ever for buyers.

The number of business acquisitions on the Australian market isn’t static, and the backdrop matters for anyone currently looking at a purchase.

Put together, this points to a large number of businesses changing hands over the next few years, a meaningful share of them without a tidy paper trail, a clear ownership transition plan, or records organised the way a buyer — or a lender — would want to see them.

That’s not a reason to be nervous about buying. It’s a reason to treat due diligence as more than a formality, and to understand early how what you find will shape what you can actually borrow.

What does due diligence have to do with getting finance to buy a business?

In short

Due diligence tells you whether a business is a good buy. It separately tells a lender whether the business is fundable. A business can pass every accounting and legal check and still come with a funding structure that looks nothing like what the buyer expected — because lenders and accountants are answering different questions from the same information.

Due diligence is usually run by an accountant and a lawyer, checking financial statements, contracts, leases, licences and compliance history. That process answers one question: is this a sound business to buy at this price?

A lender is looking at the same documents but asking a different question: if this deal goes ahead, will the cash flow support the debt, and what happens if something changes?

Those two questions don’t always land on the same answer. A business can be a genuinely good buy — strong reputation, loyal customers, solid trading history — and still come with a funding position that’s more conservative than the buyer expected, because of specific things due diligence turns up.

Illustrative example

Consider a buyer looking at an established suburban trades business — say, an electrical services company with 15 years of trading history and healthy reported profit. Due diligence uncovers that around 55% of revenue comes from two commercial clients, both on informal month-to-month arrangements rather than signed contracts. From an accounting perspective, the business is profitable and the figures check out. From a lender’s perspective, that concentration is a material risk: if either client doesn’t renew once the business changes hands, the cash flow supporting the loan could fall sharply. The business hasn’t become a worse business — but it has become a different lending proposition, and the buyer needs to know that before settling on a purchase price and a finance structure, not after.

This example is illustrative and not based on any specific client file. It’s included to show how a due diligence finding can be commercially sound and still change a lender’s view.

Why customer concentration, goodwill and owner dependence matter more than buyers expect

In short

Three due diligence findings consistently reshape lending outcomes in Australian business acquisitions: how concentrated revenue is among a small number of clients, how much of the business’s value sits in goodwill rather than hard assets, and how dependent day-to-day performance is on the outgoing owner. None of these are deal-breakers on their own — but each one changes how a lender prices and structures the deal.

Customer & revenue concentration

A large share of revenue with one or two clients isn’t automatically a reason to walk away — but it changes how a lender views the cash flow underneath the deal, because it changes what happens to that revenue once the current owner is no longer holding the relationship.

Goodwill & intangible value

Buyers often pay for reputation and repeat business built over years — real value, but genuinely difficult for a lender to recover if the deal doesn’t work out. Lenders typically weight goodwill differently to tangible assets like equipment or property.

Owner dependence

How much of the business’s performance is tied to the outgoing owner personally — their relationships, reputation, day-to-day involvement — versus systems, staff and processes that transfer with the sale. A business that runs on the owner’s personal network is a different funding proposition to one that runs on documented processes and a stable team, even if the historical financials look identical.

Illustrative example

Two businesses in the same industry, both turning over roughly the same revenue, can receive very different lending outcomes. One has documented processes, a management team that isn’t the owner, and diversified customers. The other is entirely dependent on the owner’s personal relationships and has no second-in-charge. On paper, the financials might look similar. In due diligence — and in a lender’s assessment — they are not the same deal at all.

Should I sort out finance before or during due diligence?

In short

Run due diligence and the finance conversation in parallel, not one after the other. The documents your accountant and lawyer are already reviewing are largely the same documents a lender will want to see — so pulling them together once, with a broker involved from the start, means you find out how a lender views the deal while there’s still room to negotiate, rather than after you’ve committed to settlement terms.

The most practical approach for Australian buyers is to treat due diligence and the finance conversation as one process, not two.

The financial statements, lease agreements, supplier and customer contracts, licences and staff arrangements your accountant and lawyer are reviewing are largely the same documents a lender will want to see. Pulling them together once — and having a broker look at them alongside your accountant — means you find out early how a lender is likely to view the deal, rather than discovering it after you’ve paid a deposit and started negotiating settlement terms.

Broker and business buyer reviewing documents together at a table

This is also where a broker’s perspective genuinely differs from an accountant’s. An accountant is typically assessing whether the business is a sound purchase. A broker who has previously worked on the lending side is looking at the same information and asking a slightly different question: how would a credit team read this file, and what needs to be addressed before they’ll support the number the buyer has in mind. Having both views early — rather than the finance view arriving late — is usually what determines whether settlement runs smoothly or gets renegotiated at the last minute.

What do lenders generally look for when assessing a business acquisition?

In short

While every lender and every deal is different, five factors consistently shape how an Australian lender views a business acquisition: cash flow and serviceability, customer and revenue concentration, owner dependence, the mix of tangible and intangible assets, and the stability of leases and key contracts.

Cash flow & serviceability

Whether demonstrated cash flow supports the level of borrowing proposed, not just the headline purchase price.

Customer & revenue concentration

How reliant the business is on a small number of clients or contracts, and what happens to that revenue once ownership changes.

Owner dependence

How much performance is tied to the outgoing owner personally, versus systems, staff and relationships that transfer with the sale.

Asset mix

The split between tangible assets (equipment, stock, property, vehicles) and intangible value like goodwill, treated quite differently when assessing security.

Lease & contract terms

Whether key leases, supplier agreements and customer contracts are transferable, current, and stable well beyond settlement.

None of this means a buyer needs to pre-empt every lender criterion themselves, or become an expert in credit assessment. It means the earlier these factors are identified and discussed with a broker, the more realistic the funding conversation is — and the fewer surprises there are close to settlement.

A practical way to bring finance into due diligence

In short

There’s no need to run two separate processes. Start due diligence as normal with your accountant and lawyer, flag anything that could shift a lender’s view as it comes up, get an early indicative read on your funding position, and use a structured checklist so nothing falls between what your accountant is checking and what a lender will want to see.

There’s no need to run two separate processes. A workable approach looks like this:

  1. Start due diligence as you normally would, with your accountant and lawyer leading the checks on financials, contracts, leases and compliance.
  2. Flag anything that could shift a lender’s view as findings come in — customer concentration, lease terms, goodwill weighting, staff dependency — and get an early read on how each one affects fundability, not just valuation.
  3. Get an indicative sense of your funding position early, rather than waiting until you’re ready to submit a formal application.
  4. Use a structured checklist so nothing falls through the gap between what your accountant is reviewing and what a lender will actually want to see.

Why finance-broker input matters alongside your accountant’s

In short

An accountant and lawyer answer whether a business is a sound purchase. A broker with lending-side experience answers a different question — how a credit team is likely to read the same file — and having that answer early, rather than after an offer is accepted, is often what determines whether settlement runs smoothly.

Most Australian buyers already know to bring in an accountant and a lawyer for due diligence. Fewer bring in a broker at the same stage — and that’s usually a timing gap rather than a deliberate choice, since finance is often thought of as the last step rather than a parallel one.

This is also where a broker’s perspective can differ meaningfully from an accountant’s. An accountant is typically assessing whether the business is a sound purchase, and a lawyer is assessing whether the contract and structure are sound. A broker who has previously worked on the lending side is looking at the same information and asking a slightly different, more specific question: how would a credit team read this file, and what would they want addressed before they’ll support the number the buyer has in mind.

That’s not a more important question than the accountant’s or lawyer’s — it’s a complementary one. Having all three views early, rather than the finance view arriving late, is usually what determines whether settlement runs smoothly or gets renegotiated in the final weeks before completion.

Where this matters most in practice is timing: a buyer who only approaches a lender after signing a contract has far less room to adjust price, structure or terms than a buyer who understood the likely funding position while due diligence was still underway.

Where to go from here

In short

If you’re partway through due diligence on a business, get a read on how a lender is likely to view the deal before you’re deep into settlement terms — not after. Use the due diligence checklist and acquisition finance calculator as starting points, and speak with a broker before you’re locked into a position you can’t renegotiate.

If you’re partway through due diligence on a business and want a clearer read on how a lender is likely to view the deal, that’s a conversation worth having before you’re deep into settlement terms — not after.

Frequently Asked Questions

Does due diligence affect how much I can borrow to buy a business?

Yes. Due diligence findings — including customer concentration, owner dependence, lease terms and the split between tangible assets and goodwill — directly influence how a lender assesses cash flow, risk and serviceability. Two businesses with similar revenue can receive different funding outcomes depending on what due diligence uncovers.

Should I involve a finance broker before or after due diligence?

It’s generally more useful to involve a broker during due diligence rather than after it’s complete. Many of the documents your accountant and lawyer review — financials, leases, contracts — are the same documents a lender wants to see, so reviewing them together early can surface a realistic funding picture while there’s still room to negotiate price or terms.

What do lenders look for when assessing a business acquisition?

Commonly considered factors include cash flow and serviceability, customer and revenue concentration, owner dependence, the mix of tangible versus intangible assets, and the stability of leases and key contracts. Every lender and deal differs, and this list is general and educational rather than a guarantee of how any specific lender will assess a particular business.

Is customer concentration always a problem for business acquisition finance?

Not automatically. A concentrated customer base doesn’t mean a business is a poor purchase, but it is a factor lenders consider carefully, because it affects how stable the cash flow is likely to be once ownership changes. Understanding this early allows a buyer and their broker to structure the deal or funding request accordingly.

What’s the difference between the due diligence checklist and this article?

Our Due Diligence Checklist is a practical, step-by-step reference for what to check when buying a business. This article focuses on a related but different question: how those due diligence findings feed into what a lender will actually fund, and when to bring finance into the conversation.

Can Probiz help if I’m already partway through due diligence?

Yes. If due diligence is already underway, a broker can review what’s been found so far and give an indicative view of how a lender is likely to assess the deal, which can still inform negotiation, structure and timing ahead of settlement.
