How to Evaluate a Digital Business Before You Buy

Buying a digital business is one of the most asymmetric investments available today. Done right, you can acquire a revenue-generating asset for 2–4x annual profit and immediately start collecting returns. Done wrong, you can pay a premium for a business that collapses the moment you take over.

The difference between these outcomes almost always comes down to due diligence. This checklist covers every critical area you need to evaluate before writing a check.

1. Revenue: Is the Money Real and Recurring?

Revenue is the starting point for any valuation — but not all revenue is created equal. Before anything else, verify:

• Proof of payment: Request Stripe, PayPal, or bank statements for at least 12 months. Never rely on screenshots alone.
• Revenue breakdown: Separate one-time payments from recurring subscriptions. Recurring revenue (MRR/ARR) is far more valuable.
• Revenue concentration: Is 80% of revenue coming from one customer? That's a massive risk — if they leave, so does the business.
• Refund and chargeback rate: High refund rates signal product-market fit issues or misleading marketing.
• Seasonality: Does revenue spike in certain months? Understand the pattern before assuming averages reflect reality.

Ask for read-only access to the payment processor dashboard. Any seller unwilling to provide this is a red flag.

2. Traffic: Where Do the Customers Come From?

A business that depends entirely on one traffic source is fragile. If that source disappears — an algorithm change, a ban, a policy shift — the business can collapse overnight.

• Request Google Analytics access (read-only). Verify the traffic data matches the revenue claims.
• Analyze traffic sources: Organic SEO is the most durable. Paid ads can disappear if the budget stops. Social traffic is volatile.
• Check traffic trends: Is it growing, stable, or declining? A declining trend before the sale is a major warning sign.
• Evaluate SEO health: Use Ahrefs or SEMrush to check domain authority, backlink profile, and keyword rankings. Has the site been penalized?
• App Store metrics (for mobile apps): Check download trends, ratings, review sentiment, and whether the app ranks for its core keywords.

3. Churn: Are Customers Staying?

For subscription businesses, churn is the most important metric after revenue. A business with $10k MRR and 15% monthly churn is worth far less than one with $8k MRR and 2% churn.

• Monthly churn rate: What percentage of subscribers cancel each month? Under 3% is healthy; above 8% is a serious problem.
• Net Revenue Retention (NRR): Does expansion revenue from existing customers offset churn? NRR above 100% means the business grows even without new customers.
• Cohort analysis: How long do customers typically stay? Request cohort data from the seller if available.
• Cancellation reasons: If the business surveys cancellations, what are the most common reasons? This reveals product weaknesses you'll inherit.

4. Costs and Margins: What Do You Actually Keep?

Revenue is vanity, profit is reality. Make sure you understand the full cost structure:

• Hosting and infrastructure: AWS, GCP, or managed hosting costs. Will these scale with growth?
• Third-party tools and APIs: Stripe fees, Twilio, email services, data providers — these add up.
• Team and contractors: Is the seller personally running everything? If so, can you realistically do the same, or will you need to hire?
• Customer support volume: How many hours per week does support require? Is this outsourced or owner-operated?
• True owner earnings: Calculate Seller's Discretionary Earnings (SDE) — profit plus owner's salary/time — to get the real picture.

5. Transfer Risk: Will It Survive the Handover?

Many digital businesses are deeply tied to the founder — their relationships, knowledge, brand presence, and skills. When they leave, value can evaporate. Assess:

• Documentation: Is there an operations manual, SOPs, or at minimum a detailed handover guide? Undocumented processes are a liability.
• Technology ownership: Is all code owned by the business? Are there custom systems that only the seller understands?
• Supplier and partner relationships: Are contracts in the business name or the founder's personal name?
• Domain and brand assets: Verify ownership of domains, trademarks, social accounts, and app store listings — all transferable and clear of encumbrances.
• Seller transition support: Will the seller provide training? A 30–90 day support period is standard in good acquisitions.

6. Legal and Compliance: Are There Hidden Liabilities?

• Terms of Service and Privacy Policy: Are they current, compliant with GDPR/CCPA, and actually enforced?
• Intellectual property: Is all content, code, and design original or properly licensed?
• Outstanding disputes: Any pending lawsuits, chargebacks in dispute, or regulatory issues?
• App Store compliance: For mobile apps, any history of policy violations or removal threats?

The Due Diligence Scorecard

Before making an offer, score each category on a 1–5 scale:

• Revenue quality and verifiability
• Traffic diversity and stability
• Churn rate and retention health
• Profit margins and cost structure
• Transfer risk and documentation
• Legal and compliance cleanliness

A business scoring 4–5 across all categories commands a premium multiple. A business with several 2s and 3s should be priced accordingly — or passed on.

Final Thought: Trust, but Verify

Most sellers are honest. But the stakes are high enough that you should verify every claim independently. Good sellers expect thorough due diligence — it signals you're a serious buyer and protects both parties.

If a seller pushes back on reasonable verification requests, that's your answer.
