TL;DR: The Quick Summary
- Valuation is the foundation: Don't guess; use a defensible multiplier of your EBITDA to find a fair price.
- Cash Flow is King: Structure your debt repayments so they don't exceed what the business actually earns.
- Mix your funding: Combine bank loans, vendor finance (from the partner), and potentially property equity to keep interest rates low.
- Baseline’s 7-Day Edge: Our Strategic Funding Plan maps out your entire buyout journey in a week, ensuring no surprises.
Breaking up is hard to do. It’s even harder when there are GST registrations, payroll cycles, and a shared lease on an industrial unit in Osborne Park involved.
Whether your partner is retiring, moving on to a new venture, or you’ve simply reached a fork in the road, buying out a business partner is one of the most significant moves you’ll ever make. It’s a moment of huge opportunity, but if you get the financing wrong, you’re not just buying a stake, you’re buying a massive, cash-sucking headache.
As a specialist mortgage broker for businesses, we see people try to "wing it" all the time. They agree on a price over a coffee, walk into a Big Four bank, and get hit with a "computer says no" because they didn't have a plan.
Let's change that. Here is your blueprint for a clean exit that keeps your business healthy and your stress levels low.
Section 1: The Valuation Game (Stop Guessing)
Before you talk to a lender about business acquisition loans in Australia, you need to know what you’re actually buying. A business valuation isn't just about what's in the bank account today; it's about the future.
Most small-to-medium enterprises (SMEs) in WA are valued on a "multiple" of their earnings (EBITDA). If your business makes $500,000 a year in profit and the industry standard multiple is 3x, the business is worth roughly $1.5 million. If your partner owns 50%, you need $750,000.
But wait, don't forget to "normalise" those earnings. If your partner has been taking a massive salary or the business paid for their personal Range Rover, those costs need to be added back to the profit to show the true value.
"A fair valuation is the only way to ensure the departing partner feels respected while the remaining partner doesn't start their solo journey underwater."
Section 2: Cash Flow is the Real Boss

Here’s where most people trip up: they focus on the price instead of the repayments. You might be able to get a $1 million loan, but can the business actually pay it back without cutting staff or stopping marketing?
Lenders use something called a Debt Service Coverage Ratio (DSCR). In plain English: they want to see that for every $1 you owe them in interest and principal, the business earns at least $1.25 to $1.50 in free cash.
If your repayments are too high, your business becomes "fragile." One bad month or one late-paying client, and you’re in trouble. This is why we often suggest a mix of working capital solutions to sit alongside your main acquisition loan, ensuring you have a buffer for the day-to-day.
Section 3: The Funding Menu (How to Pay for It)
You don't have to get all the cash from one place. In fact, the smartest buyouts use a "layer cake" approach to funding.
1. Traditional Bank Loans
Standard term loans are great because they have lower interest rates, but banks are famously picky. They will want to see three years of solid tax returns and will likely ask for security.
2. Vendor Finance (The Secret Weapon)
This is where the exiting partner acts as the bank. You pay them, say, 70% upfront and the remaining 30% over three years with interest. It shows the bank that the old partner is confident in the business’s future, which actually makes the bank more likely to lend you the rest.
3. The Shadow Collateral Play
If your business doesn't have huge physical assets (like a fleet of trucks), the bank might ask for a "lack of deposit" solution. We often suggest using the equity in your home or an investment property as security. By securing the business loan against property, you can often unlock much lower interest rates and longer repayment terms. Check out our home loan guidance to see how your personal assets can fuel your professional growth.
4. Asset Finance
If your business owns machinery, vehicles, or heavy equipment, you can "refinance" these assets to pull cash out of the business. It’s a clever way to fund a buyout without taking on a traditional "business loan." Learn more about asset finance here.
Section 4: The 7-Day Strategic Funding Plan

At Baseline Finance, we don't believe in "waiting and seeing." When you're in the middle of a partner buyout, the tension is high. You need answers fast.
That’s why we developed our Strategic Funding Plan. Within 7 days, we provide:
- A borrowing power assessment: Exactly how much the banks will give you.
- A structure recommendation: Should you use vendor finance? Should you top up your mortgage?
- A cash flow stress test: What happens to your solo income after the debt is paid?
- A roadmap to settlement: Every step from today until the day the shares transfer.
It’s about moving from "I hope this works" to "I know this works."
Section 5: Your Buy-Out Runway (Step-by-Step)
- The "Kitchen Table" Chat: Agree on the intent to buy/sell with your partner.
- The Valuation: Get a professional or an accountant to run the numbers.
- The Baseline Strategy: Call us. We’ll build your Strategic Funding Plan and show you the best acquisition finance options.
- The Loan Approval: We handle the bank negotiations and paperwork. You keep running the business.
- Legal Documentation: Your lawyer draws up the Share Sale Agreement (SSA).
- Settlement: The funds move, the shares transfer, and you’re officially the captain of the ship.
Glossary: Terms to Know
- EBITDA: Earnings Before Interest, Taxes, Depreciation, and Amortisation. Basically, your "real" profit before the accountants get fancy.
- Vendor Finance: A loan provided by the seller to the buyer.
- Security/Collateral: An asset (like a house or a warehouse) that the bank can claim if you stop paying the loan.
- Covenant: A rule the bank sets (e.g., "You must keep $50k in the bank at all times").
- DSCR: Debt Service Coverage Ratio: your ability to pay the loan back.

The Bottom Line
A partner buyout shouldn't be a battle; it should be a transition. By structuring your finance correctly, you can ensure the person leaving is happy, and the person staying (that's you) has a business that is actually capable of growing.
