Financial Red Flags Checklist: What to Look for When Buying a Business in Australia
A financial red flags checklist for buying a business in Australia is a structured list of warning signs that indicate a business's reported financials may not tell the complete story. Most sellers present numbers that look reasonable in isolation — and most buyers don't have the training to know what to check against what. This checklist gives you 47 specific things to verify across revenue, costs, tax, cash flow, and the balance sheet before you put a dollar on the table.
Most of the deals that go bad don't go bad because the buyer missed something obvious. They go bad because the buyer checked the P&L, saw a reasonable profit number, and didn't ask the next question. This checklist is the next question — repeated 47 times.
Why financials get dressed up before a sale
Sellers preparing a business for sale have a strong incentive to make the numbers look as good as possible. That's not always dishonest — sometimes it's just presentation choices, like expensing the owner's personal car through the business (which is fine as long as it's disclosed), or timing a large maintenance expense to land outside the review period. But sometimes it's more deliberate.
I reviewed a landscaping business in Queensland where the P&L showed $180,000 in profit over the prior year. When I got into the bank statements (which the broker initially resisted providing), the actual cash that had flowed through the account was $130,000. The difference was a handful of invoices that had been raised, included in revenue, but never collected. The business had booked $50,000 in income it had never received. The seller called it "timing" (which is one way to describe it, I suppose).
Understanding the gap between accounting profit and actual cash is the single most important thing you can learn before doing due diligence on a small business. It's also the first section of this checklist.
What this checklist covers
The full checklist is organised into six phases:
Phase 1 — Cash vs Profit reconciliation. The most dangerous gap in any set of small business accounts. You're checking whether the business actually collects the cash it books as revenue.
Phase 2 — Revenue quality and sustainability. Not all revenue is equal. One-off jobs, related-party revenue, and contracts about to expire are worth far less than the same dollar figure from recurring, arms-length customers.
Phase 3 — Cost and expense manipulation. The most common form of financial dressing. Personal expenses through the business, deferred maintenance, and suspiciously flat cost lines all appear here.
Phase 4 — Tax and BAS compliance. Unpaid ATO obligations follow the business, not the seller — in a share sale especially, you can inherit years of GST shortfalls or PAYG non-compliance. This phase covers what to verify with the ATO directly.
Phase 5 — Balance sheet traps. Accounts receivable that will never be collected, stock that's been sitting for three years, director loans that complicate a clean exit. The balance sheet tells a different story from the P&L — you need both.
Phase 6 — Owner-related adjustments. The seller's salary, perks, and personal expenses running through the business. Every buyer adjusts for these; the question is whether the seller is being honest about what they are.
