How to Build a Winning Pitch Deck for Selling Your Established Business Software Company (with a free PowerPoint template to download)

Most advice on creating a pitch deck is aimed at start-ups, but what if you're selling a profitable business software company? Buyers of established software businesses aren’t looking for the next big thing—they want a stable, profitable, and well-run company with clear financials, strong customer retention, and predictable growth.

At Ishikawa Technologies, we specialise in acquiring and optimising mature software businesses. Based on our experience, many sellers oversimplify their product portfolio, fail to provide a detailed financial breakdown, or focus too much on future potential rather than present realities.

If you’re preparing a pitch deck for a business sale, here’s how to create a compelling, transparent, and detailed presentation that attracts serious buyers.

1. Executive Summary: Honesty Over Hype

Buyers don’t want exaggerated claims or vague future projections. They want clear financials, key performance indicators (KPIs), and an accurate picture of your customer base and product stability.

What to Include:

Key Financials (Last 5 Years, Broken Down by Product & Service):
- Recurring vs. non-recurring revenue
- Gross margin, net profit, capital costs, and amortisation
- Fully loaded customer acquisition cost (CAC), including brand-building attribution
- Customer lifetime value (CLTV)
- Gross and net churn
- New customer revenue vs. upsell/downgrade revenue
- Cost of goods sold (COGS), including customer support and hosting
- Monthly cash flow and balance sheet (where all revenue beyond year one is in long-term liabilities)
Ideal Customer Profile (ICP) for Each Product:
- Who your best-fit customers are
- The business problem each product solves
- How deeply embedded your software is in their operations
Pricing Strategy & History:
- Historical pricing, changes, and rationale
- Enterprise vs. small business pricing models
- Discounting trends

Buyers are looking for stability and predictability. If a product is declining in growth but still generating strong revenue, be upfront about it. Mismatched expectations lead to frustration and lost deals.

2. Comprehensive Product Breakdown: Don’t Oversimplify

Unlike start-ups, mature software companies typically have multiple products, some of which may be legacy offerings generating significant revenue.

Instead of only showcasing the most promising areas, give buyers a complete view of your portfolio.

For Each Product, Provide:

Revenue contribution & growth trends
Contract length & renewal patterns
Target industries & key customers
Pricing model & history
Customer adoption levels & feature usage
Comparison with competitors, focusing on technical advantage

Don't focus only on high-growth areas. If a legacy product makes up a large percentage of revenue, buyers need to understand its stability, maintenance costs, and migration challenges.

3. Operational Overview: The Real Backbone of Your Business

The success of a mature software company depends on operational efficiency, technical execution, and staffing stability. Buyers aren’t just evaluating products—they’re evaluating how well the business is run.

Key Operational Details to Include:

Staffing Trends & Organisation Structure
- Headcount changes over five years
- Breakdown by department (engineering, support, sales, etc.)
- Turnover rates and key personnel
Technical Debt & Product Roadmap
- Percentage of product reliant on legacy code
- Upgrade/migration strategy
- Product lifecycle management
Customer Support & Professional Services
- Support ticket volume, resolution times, and major challenges
- Professional services revenue and utilisation rates
- % of customers relying on managed services
Cloud Migration Strategy (if applicable)
- If transitioning from on-premise to cloud, what’s the migration plan?
- Risk of churn during transition and mitigation strategies

Buyers will uncover operational inefficiencies during due diligence, so being proactive in disclosing them builds trust and credibility.

4. Customer Stickiness & Retention: The Key to Business Value

For a buyer, customer stickiness is far more important than new sales growth. A business with high retention and strong upsell potential is far more valuable than one that relies on constant new customer acquisition.

Essential Metrics to Provide:

Net Revenue Retention (NRR) – How much existing customers expand spending
Churn Breakdown – Gross churn, net churn, voluntary vs. involuntary churn
Upsell & Cross-Sell Trends – How existing accounts grow over time
Customer Dependency ("Grandcustomer" Effect) – If your software is embedded in your customers’ customer workflows, switching costs increase significantly

If a large percentage of customers remain on older versions, outline a clear migration strategy to ensure ongoing revenue stability.

5. Full Financial Transparency: What Buyers Expect to See

Unlike start-ups, mature businesses must provide detailed financial breakdowns covering multiple years, broken down by product, service, and contract type.

Financial Documents to Include:

Income Statement (5 Years)
- Revenue (Recurring vs. Non-Recurring)
- Gross & Net Profit
- EBITDA
Balance Sheet (With Proper Revenue Recognition)
- All revenue beyond year one should be categorised as long-term liabilities
Monthly Cash Flow Statement
- Cash inflows, outflows, and working capital trends
Customer Acquisition Costs (Fully Loaded)
- Marketing, sales, and brand-building costs
- Breakdown by new customer revenue vs. upsell revenue
Product-Level Unit Economics
- Gross margin per product
- Hosting, support, and cost-to-serve

Valuation Expectations

1-3x Annual Recurring Revenue (ARR)
4-6x EBITDA, depending on growth and profitability

If a business has high margins and strong retention, it will command a higher multiple. However, if CAC is high or churn is creeping up, valuation will be impacted.

6. Future Growth: Grounded in Realism, Not Hype

Buyers are not looking for speculative market expansion—they want low-risk, achievable growth strategies.

Key Growth Opportunities to Highlight:

Pricing Optimisation – Are there untapped margin improvements?
Sales Expansion – Could a different sales motion increase revenue?
New Market Expansion – If moving into new industries or geographies, show existing traction, not just potential

Investors and buyers don’t want a "blue sky" vision. They want a business where growth is executable with minimal risk.

7. Technical Architecture & Integration: How Your Product Fits a Buyer’s Portfolio

For many buyers—especially strategic acquirers and private equity firms rolling up multiple software businesses—one of the most critical factors is how your product will integrate into their existing ecosystem.

If your software is highly interoperable, uses modern APIs, or has existing integrations with widely used platforms, this could be a major selling point. Conversely, if your product is built on outdated technology with limited integration capabilities, buyers need to know what challenges they may face.

What Buyers Want to Know:

Technical Architecture Overview:
- Is the product cloud-native, on-premise, or hybrid?
- What tech stack and frameworks are used? (E.g., AWS, Azure, .NET, Java, PHP, etc.)
- How is security and compliance managed?
Interoperability & Existing Integrations:
- What third-party applications does your product currently integrate with? (E.g., Salesforce, SAP, HubSpot, Microsoft 365)
- Is integration done via open APIs, webhooks, middleware, or proprietary connectors?
- How easy is it for a buyer to extend integrations to new platforms?
Data Integration & Migration Capabilities:
- Can the product easily ingest, export, or sync data with other systems?
- What database architecture does it use? (E.g., relational, NoSQL, in-memory)
- Are ETL (Extract, Transform, Load) processes in place for large-scale data migrations?
- How much effort is required to onboard customers from another system?

Why This Matters to Buyers

Strategic buyers often need to cross-sell or bundle your software with their existing products. If your software can seamlessly integrate into their ecosystem, it may increase the value of the deal.

For example:

A SaaS acquirer may prefer products with RESTful APIs for quick integrations.
A legacy software buyer may be willing to invest in product modernisation but will want clear documentation on technical debt.

How to Present This in Your Pitch Deck

Include a technical architecture diagram showing major system components.
List key integrations and how they benefit customers.
If applicable, explain how a cloud migration or API upgrade strategy is already in motion.
