What is due diligence when buying a business?

Due diligence is the process of thoroughly investigating a business before you commit to buying it. It involves reviewing financial records, legal obligations, operational systems, and market position to confirm that what the seller claims about the business is accurate and complete.

Think of it as your opportunity to look under the bonnet before signing on the dotted line. You're checking for hidden debts, unresolved legal disputes, declining revenue, employee issues, and any other risks that could affect the value or viability of the business.

In South Africa, due diligence also includes verifying compliance with local regulations such as the Companies Act, Broad-Based Black Economic Empowerment (B-BBEE) requirements, and tax obligations with the South African Revenue Service (SARS). Skipping this step can leave you exposed to liabilities you didn't know existed.

Steps to buying a business in South Africa

Buying a business is a significant financial decision, and following a structured process helps you avoid costly mistakes. Here are the 6 key steps to guide you from initial search through to closing the deal.

1. Find the right business

Start by identifying the type of business that matches your skills, experience, and financial capacity. Browse online marketplaces like BizBuySell South Africa, Gumtree Business, or industry-specific listings. You can also work with a business broker who specialises in matching buyers with suitable opportunities.

Consider the industry, location, size, and growth potential of each option. It's worth creating a shortlist of criteria before you start searching so you can evaluate opportunities objectively rather than emotionally.

2. Understand why it's for sale

The reason a business is on the market tells you a lot about what you're getting into. Common reasons include retirement, relocation, partnership disputes, or a desire to pursue other ventures. These are generally low-risk scenarios.

However, if the business is for sale because of declining revenue, increased competition, or operational difficulties, you'll need to dig deeper. Ask the seller directly and verify their answers during due diligence. A seller who's reluctant to explain their reasons is a red flag worth noting.

3. Value the business

Before entering negotiations, you need an accurate picture of what the business is actually worth. This goes beyond just looking at revenue; you'll need to consider assets, liabilities, cash flow, market conditions, and growth potential.

It's advisable to engage a professional business valuator or your accountant to conduct a formal valuation. They'll use established methods to arrive at a fair price range, giving you a solid foundation for negotiations. You can read more about valuation methods in the section below.

4. Conduct due diligence

This is where you verify every claim the seller has made about the business. Request access to financial statements, tax returns, contracts, employee records, and operational documents. Review them carefully, ideally with the help of an accountant and a lawyer.

Due diligence typically takes 30 to 90 days, depending on the complexity of the business. Don't rush this step. Uncovering a problem now is far less expensive than dealing with it after the sale is finalised.

5. Arrange financing

Once you're satisfied with your due diligence findings, it's time to secure the funds. Options include commercial bank loans, development finance from institutions like the Industrial Development Corporation (IDC) or Small Enterprise Finance Agency (SEFA), seller financing, partnerships, or a combination of personal savings and external funding.

Your lender will likely require a business plan, financial projections, and the due diligence report. Having these ready speeds up the approval process and demonstrates that you've done your homework.

6. Negotiate and close the deal

With financing in place, you can negotiate the final purchase price and terms. Use your due diligence findings to justify any adjustments to the asking price. Common negotiation points include the purchase price, payment structure, transition period, and any seller warranties or indemnities.

A sale of business agreement should be drafted by a lawyer and reviewed by both parties. In South Africa, you'll also need to comply with section 34 of the Insolvency Act, which protects creditors during a business transfer. Once both parties sign, you're officially the new owner.

Why is due diligence important?

Due diligence protects you from buying a business with hidden problems that could drain your finances or expose you to legal liability. Without it, you're essentially taking the seller's word for everything, and that's a risky position when significant money is on the line.

Here are some real risks that due diligence helps you uncover:

• Undisclosed debts or liabilities that transfer to you as the new owner.
• Inflated revenue figures or manipulated financial statements.
• Pending or potential legal disputes with customers, suppliers, or employees.
• Non-compliance with B-BBEE requirements, SARS obligations, or industry-specific regulations.
• Key customer or supplier contracts that expire soon or contain unfavourable terms.
• Employee disputes, pending labour cases at the Commission for Conciliation, Mediation and Arbitration (CCMA), or unfunded leave balances.

Thorough due diligence also gives you leverage in negotiations. If you identify issues, you can negotiate a lower price, request that the seller resolves problems before the sale, or include protective clauses in the agreement.

Essential due diligence checklist

A structured checklist ensures you don't overlook critical areas during your investigation. Here are the 5 key categories to cover when assessing a business for purchase in South Africa.

Financial due diligence

Financial due diligence confirms that the business's financial health matches what the seller has represented. Focus on these areas:

• Audited financial statements and management accounts for the past 3 to 5 years, including profit and loss statements, balance sheets, and cash flow reports.
• Tax returns and SARS compliance certificates to confirm there are no outstanding tax liabilities or disputes.
• Accounts receivable and accounts payable ageing reports to assess how quickly the business collects payments and settles debts.
• Revenue trends and profit margins over time, checking for seasonal patterns or declining performance.
• Outstanding loans, credit facilities, and any personal guarantees the seller has provided that may need to transfer.

Legal due diligence

Legal due diligence identifies any legal risks or obligations that could affect the business after the sale. Pay close attention to:

• Business registration documents, including the company's Memorandum of Incorporation (MOI) and Companies and Intellectual Property Commission (CIPC) filings.
• All existing contracts with customers, suppliers, landlords, and service providers, noting any change-of-ownership clauses.
• Intellectual property ownership, including trademarks, patents, and domain registrations.
• Any pending or threatened litigation, arbitration, or CCMA proceedings.
• Compliance with the Consumer Protection Act, Protection of Personal Information Act (POPIA), and any sector-specific legislation.

Operational due diligence

Operational due diligence gives you a clear picture of how the business runs day to day and whether it can function without the current owner. Review:

• Employee contracts, organisational structure, and key person dependencies to understand who keeps the business running.
• Supplier agreements and supply chain reliability, including lead times and alternative sourcing options.
• Technology systems, software licences, and IT infrastructure, including any systems that are outdated or due for replacement.
• Standard operating procedures, quality control processes, and customer service workflows.
• Physical assets such as equipment, vehicles, and property, including their condition and maintenance history.

Market position and competitive analysis

Understanding the business's position in its market helps you assess whether it has a sustainable competitive advantage. Examine:

• Market share and customer base, including customer concentration risk (whether a few clients account for most revenue).
• Competitor landscape and how the business differentiates itself in the local and national market.
• Industry trends and growth projections for the sector in South Africa.
• Customer reviews, reputation, and brand recognition in the target market.

Regulatory and compliance

South Africa has specific regulatory requirements that vary by industry. Confirming compliance before purchase protects you from inherited penalties. Check:

• B-BBEE compliance certificates and scorecards, which can affect eligibility for government contracts and tenders.
• Industry-specific licences and permits, such as liquor licences, health certificates, or financial services authorisations.
• Environmental compliance, including waste management permits and environmental impact assessments where applicable.
• Occupational Health and Safety Act compliance, particularly for businesses with physical premises or manufacturing operations.
• Municipal approvals, zoning certificates, and any outstanding rates or utility accounts.

How to value a business before buying

Knowing the fair market value of a business prevents you from overpaying and gives you a strong position in negotiations. There are 3 widely used valuation methods, and the right approach depends on the type of business you're buying.

The asset-based method calculates the value of the business based on its total assets minus total liabilities. This approach works well for businesses with significant physical assets, such as manufacturing or property-based businesses. It's straightforward but doesn't account for future earning potential or goodwill.

The market-based method compares the business to similar businesses that have recently sold in the same industry or region. This gives you a benchmark, though it can be difficult to find truly comparable sales data in South Africa's smaller markets. Business brokers and industry associations can sometimes provide useful comparison data.

The income-based method values the business based on its expected future earnings, typically using a discounted cash flow (DCF) analysis or a capitalisation of earnings approach. This method is often considered the most accurate for profitable, established businesses because it reflects what the business can actually generate going forward.

For the most reliable result, consider engaging a professional valuator who can apply multiple methods and provide an independent opinion. Your accountant can also help you interpret the numbers and identify areas where the seller's valuation may be optimistic.

How to finance buying a business

Securing the right financing is one of the most important steps in buying a business. The structure of your funding affects your cash flow, risk exposure, and ability to invest in growth after the purchase.

Commercial bank loans are the most common financing option in South Africa. Banks such as Standard Bank, FNB, Nedbank, and Absa offer business acquisition loans, though they typically require a deposit of 10% to 30%, a solid business plan, and evidence of the business's financial performance.

Development finance institutions offer another route, particularly for first-time business owners or historically disadvantaged individuals. The IDC and SEFA provide funding for business acquisitions with more flexible terms than commercial banks, though the application process can take longer.

Seller financing is an arrangement where the seller agrees to receive part of the purchase price over time. This can be attractive because it aligns the seller's interests with your success post-sale. It also signals confidence in the business's future performance.

Other options include bringing in a partner to share the financial burden, using personal savings, or combining multiple funding sources. For a detailed look at all available options, see the guide to financing your business. Whichever route you choose, ensure you've factored in working capital needs for at least the first 6 months of ownership, not just the purchase price itself.

Pros and cons of buying a business

Buying an existing business comes with clear advantages, but it's not without its challenges. Weighing both sides helps you make an informed decision.

Here are the main advantages of buying a business:

• You acquire an established brand, customer base, and revenue stream from day 1.
• Existing systems, processes, and supplier relationships reduce the time needed to become operational.
• Financial history makes it easier to secure financing compared to a startup with no track record.
• Trained employees are already in place, reducing recruitment and onboarding costs.
• You can build on existing momentum rather than starting from scratch.
• It's often easier to forecast cash flow and profitability based on historical data.

However, there are also potential drawbacks to consider:

• The upfront cost is typically higher than starting a business from scratch.
• You may inherit hidden liabilities, debts, or legal issues that weren't fully disclosed.
• The business may have a damaged reputation or outdated systems that require significant investment to fix.
• Key employees or customers may leave during the ownership transition.
• You're locked into existing contracts, leases, and commitments that may not align with your vision.

Tips for successful due diligence

Getting due diligence right can mean the difference between a sound investment and a costly mistake. These practical tips help you stay thorough and focused throughout the process.

• Start with a clear checklist and timeline. Define what you need to review, who's responsible for each area, and your target completion date.
• Hire professionals early. An accountant, lawyer, and business valuator each bring expertise you're unlikely to have on your own. Their fees are a small price compared to the cost of missing a critical issue.
• Verify everything independently. Don't rely solely on documents the seller provides. Cross-check financial figures with bank statements, confirm tax compliance directly with SARS, and speak to key customers and suppliers.
• Visit the business in person, ideally more than once and at different times. Observe operations, talk to employees (with the seller's permission), and assess the condition of physical assets.
• Pay attention to what's missing. Gaps in documentation, reluctance to share information, or inconsistencies between what the seller says and what the records show are all warning signs.
• Don't rush. Pressure to close quickly almost always benefits the seller. Take the time you need to be confident in your decision.

FAQs on buying a business

Here are some frequently asked questions about buying a business.

What happens if due diligence reveals problems with the business?

If you uncover issues during due diligence, you have several options. You can renegotiate the purchase price to reflect the risk, request that the seller resolves the problem before completing the sale, or include indemnity clauses in the agreement that protect you if the issue surfaces later. In serious cases, walking away may be the best decision.

Can I renegotiate the price after making an initial offer?

Yes. Your initial offer is typically made before full due diligence. If the investigation reveals risks or liabilities that weren't apparent, you're within your rights to adjust your offer. Use specific findings to support your revised price, and be prepared for the seller to counter or decline.

What can delay or extend the due diligence process?

Common delays include incomplete financial records from the seller, disputes over asset valuations, and slow responses from third parties such as landlords or regulatory bodies. Complex ownership structures, multiple business locations, or cross-border operations can also push the timeline well beyond the typical 30 to 90 days.

Do I need a lawyer when buying a business in South Africa?

Yes, a lawyer is strongly recommended. South African business transfers involve specific legal requirements, including compliance with section 34 of the Insolvency Act, transfer of contracts, and regulatory filings. A lawyer ensures the sale agreement protects your interests and that all legal obligations are met.

Should I buy a business as an asset sale or a share sale?

In an asset sale, you purchase specific assets (equipment, stock, customer lists) without taking on the company's existing liabilities. In a share sale, you acquire the entire company, including all its assets and liabilities. Asset sales are generally lower risk for buyers, while share sales may offer tax advantages depending on the structure. Your lawyer and accountant can advise on which approach suits your situation.
