Series A Preparation: The Founder's Technical Due Diligence Blind Spot

# Series A Preparation: The Founder's Technical Due Diligence Blind Spot

When we work with founders preparing for Series A fundraising, they typically arrive with two things: a polished pitch deck and a spreadsheet of metrics. What they often *don't* have is a clear picture of what investors are actually evaluating during due diligence.

Here's what we've learned: the conversation investors are having in the room differs significantly from the conversation they're having in the data room. The pitch focuses on vision, market opportunity, and traction. The due diligence focuses on whether your infrastructure—technical, financial, and operational—can actually support the growth story you're selling.

This gap costs founders time, credibility, and sometimes funding.

## The Technical Due Diligence Audit Investors Conduct (Before Making an Offer)

Most founders understand that Series A investors will review their financial statements. Fewer understand that they'll also conduct a detailed technical audit of your infrastructure, data governance, and operational systems.

In our work with Series A startups, we've seen founders blindsided by investor requests for:

- **Database architecture documentation** (how data flows, where it's stored, what's backed up)
- **Security and compliance certifications** (SOC 2, ISO 27001, GDPR compliance status)
- **Customer data handling procedures** (privacy policies, data retention, access controls)
- **System integration maps** (which tools talk to which, where manual processes exist, dependency risk)
- **Financial system documentation** (how revenue recognition works, audit trails, account reconciliation processes)
- **Key person dependencies** (which employees hold critical passwords, institutional knowledge, or single points of failure)

Investors don't ask for these because they're being difficult. They ask because they're assessing whether your company can handle rapid scaling without collapsing operationally. A beautiful product with weak infrastructure becomes a liability at $5M ARR.

### The Data Governance Red Flag

We worked with a B2B SaaS founder whose metrics were excellent—$2.2M ARR, 140% net revenue retention, strong product-market fit. During Series A due diligence, the investor's technical team asked for a data lineage document showing how customer usage metrics were calculated.

The founder discovered their analytics system pulled from three different databases, with two manual spreadsheet reconciliations in between. Revenue recognition happened in the accounting software but customer health metrics came from a different system entirely. The founder couldn't actually prove which numbers were source-of-truth.

This wasn't a deal-killer, but it cost two weeks of diligence process and required the founder to commit to a post-close systems remediation. The investor ultimately funded, but with tighter financial controls requirements built into the term sheet.

**Lesson:** Series A preparation means documenting how your critical business metrics actually flow through your systems, and being able to explain why.

## The Financial Infrastructure Verification Process

Investors approach financial due diligence systematically. They're not looking for accounting mistakes (though they'll catch those). They're looking for whether your financial infrastructure can survive being 10x bigger while still providing accurate reporting.

### What Gets Audited

**Revenue Recognition Process**
Investors request documentation of your revenue recognition policy, then they trace it. They'll pick 10-20 customer contracts and verify that revenue was recognized according to policy. They'll check for side letters, verbal agreements, or unusual contract terms that might affect when revenue actually hits. They want to understand:

- Do you have documented revenue recognition policies aligned with ASC 606?
- Are there exceptions or manual adjustments to standard policy?
- Can you trace a contract from signature through revenue recognition in your financial statements?

**Expense Recording and Accruals**
Investors will sample your expense transactions—checking that the dollar amount, vendor, and accounting classification are accurate. More importantly, they'll review your month-end accrual process. Are you consistently accruing expenses? Are there large month-to-month variations that suggest inconsistent accrual practices?

We've had clients where the finance team manually remembered to accrue some expenses but not others, creating artificial month-to-month volatility. Investors notice this and flag it as financial reporting risk.

**Cash Flow Forecasting Accuracy**
Investors will compare your historical cash flow forecasts (from 12 months ago) against actual results. If your forecasts were consistently off by 20%+ in the same direction, they'll question your financial planning assumptions. This affects how much runway they believe you actually have.

We recommend starting this comparison immediately. [The Cash Flow Visibility Gap: Why Founders Manage By Surprise](/blog/the-cash-flow-visibility-gap-why-founders-manage-by-surprise/) Pull your cash flow forecast from 12 months ago and compare it to what actually happened. If the variance is significant, document why. This gives you narrative control during diligence rather than defensive reactivity.

**Balance Sheet Integrity**
Investors will verify major balance sheet items:
- Are capitalized software development costs actually capitalized and properly amortized?
- What's sitting in accounts receivable that's over 90 days old?
- Are there intercompany transactions that need elimination?
- Are prepaid expenses and deferred revenue properly categorized?

Investors specifically look for "accounting surprises"—items that were recorded wrong and need restatement. Finding these before investors do is critical.

## The Operational Systems Stress Test

Beyond financial systems, investors assess whether your operational infrastructure can scale. Here's what they're investigating:

### People and Process Documentation

Investors want to understand your processes independent of the people executing them. Red flags include:

- **No documented processes.** If the CFO leaving means nobody else can close the books, that's a major problem.
- **Spreadsheet-dependent workflows.** If your billing system depends on a weekly Excel reconciliation, you have scaling risk.
- **Missing access controls.** Who can approve expenses? Who can modify customer contracts? Who has database access? If answers are vague, investors worry about fraud risk and compliance issues.

When preparing for Series A, document your critical processes and ensure at least two people understand each one. This isn't bureaucracy—it's proof that your company can run without any single person being irreplaceable.

### Technology Debt Assessment

Investors don't conduct code reviews (that's for technical founders in special situations), but they do ask about technology debt. They want to know:

- What legacy systems are slowing down product development?
- Are you maintaining multiple product versions?
- How much engineering capacity goes to technical debt vs. feature development?
- What happens if a core vendor (like your payment processor or cloud provider) changes their terms?

Be honest about this. Investors understand that every growing company has technical debt. They're assessing whether you've *acknowledged* it and have a plan to address it, not whether it exists.

## The Metrics Verification Deep Dive

We've covered [SaaS unit economics metrics](/blog/saas-unit-economics-the-benchmarking-trap-that-breaks-growth/) in detail elsewhere, but during Series A due diligence, investors verify these metrics differently than you might calculate them.

### The Calculation Audit

Investors will ask for your customer cohort analysis—showing how customers acquired in different months perform. They'll verify your churn calculation (which should exclude churned customers already counted in previous periods). They'll trace expansion revenue to actual customer contracts.

Here's where founders get caught: your internal metrics dashboard might calculate MRR one way, your sales team might use different numbers, and your financial statements might show revenue recognized slightly differently. Investors will spot these gaps.

Prepare by reconciling your metrics to your general ledger. If revenue in your metrics dashboard doesn't match revenue in your financial statements, you need to explain why and fix it.

### Growth Rate Verification

Investors want to verify growth rates by looking at historical financial statements or bank deposits, not just dashboards. They're checking:

- Does your reported growth match what's in your audited financial statements?
- Are there one-time items that inflated growth (like a large customer acquired in unusual circumstances)?
- How much of growth is organic vs. expansion vs. acquisition?

If you're claiming 120% YoY growth, investors will trace that through your bank deposits and customer contracts. Inconsistencies here are credibility-killers.

## Preparing Your Technical and Operational Due Diligence Package

Here's what we recommend preparing before you begin Series A fundraising:

### Documentation Checklist

- **Financial policies document** (revenue recognition, expense capitalization, reserve policies)
- **System architecture diagram** (what tools you use, how they integrate, where manual processes exist)
- **Security and compliance status** (what certifications you have, what you're working toward, timeline)
- **Key person dependency list** (critical roles and if there's backup coverage)
- **Process documentation** for: month-end close, customer onboarding, contract approvals, expense approvals
- **Historical financial statements** (last 24 months of clean P&Ls, ideally audited or reviewed)
- **Metrics reconciliation schedule** (showing how dashboard metrics tie to financial statements)
- **Customer contract terms summary** (payment terms, contract length, any unusual terms)

### The 90-Day Preparation Window

Ideally, you start preparing for Series A technical due diligence 90 days before you begin actively fundraising. This gives you time to:

**Month 1: Audit and Document**
- Identify gaps in process documentation
- Verify financial metrics tie to general ledger
- Assess security/compliance certifications
- Document system architecture

**Month 2: Remediate**
- Create missing process documentation
- Fix financial metric calculation discrepancies
- Begin security certification process if needed
- Reduce people-dependent critical processes

**Month 3: Prepare Investor Package**
- Organize all documentation
- Create summary narratives explaining any gaps
- Prepare data room
- Brief your team on what to expect

## Common Mistakes We See Founders Make

### Mistake 1: Over-Preparing on Pitch Metrics, Under-Preparing on Verification

Founders spend weeks perfecting their growth charts but haven't verified that the numbers in those charts actually match their financial statements. Investors notice this immediately.

### Mistake 2: Not Understanding Your Own Revenue Recognition

You'd be surprised how many founders can't explain exactly when revenue gets recognized in their accounting system. If the investor's accountant asks this question and you don't have a clear answer, they flag it as risk.

### Mistake 3: Hidden Technical Debt

Don't minimize or hide your technology challenges. Investors assume every growing company has technical debt. What they're assessing is whether you acknowledge it and have a plan. Discovered hidden debt during due diligence damages credibility.

### Mistake 4: Inconsistent Metrics Across Sources

Your board deck shows one number, your dashboard shows another, and your financial statements show a third. Investors will notice. Pick one source of truth for each metric and ensure everything ties to it.

### Mistake 5: Critical Process Gaps

If your CFO is the only person who understands your month-end close process, that's a risk factor. Investors want to see that your company has documented processes independent of any single person.

## The Post-Offer Due Diligence Reality

Here's something founders need to understand: getting a verbal offer isn't the finish line for due diligence preparation. Once you have a term sheet, investors typically spend 4-8 weeks in detailed due diligence before closing.

This is where technical and operational issues surface. We've seen investments delayed because investors discovered during final due diligence that:

- Revenue wasn't being recognized according to the stated policy
- Key customer contracts had unusual terms that created contingent liability
- The billing system couldn't support the company's claimed feature set
- There were significant undocumented process gaps

None of these were deal-killers, but they delayed closing and required negotiations around financial controls, indemnification, and representations.

You avoid this by being thorough with Series A preparation. An investor would rather discover (and understand) your challenges during initial diligence than be surprised during final verification.

## Your Series A Preparation Action Plan

If you're planning Series A fundraising in the next 6-12 months:

1. **This week:** Reconcile your growth metrics to your financial statements. If they don't match, figure out why.

2. **This month:** Document your month-end close process, your revenue recognition policy, and your critical operational processes.

3. **Next month:** Verify that your security/compliance status is clear. If you need SOC 2 or other certifications, start the process now—these take 2-3 months.

4. **Ongoing:** Identify and reduce single-point-of-failure dependencies in critical processes.

The founders who raise Series A most efficiently aren't the ones with perfect metrics—they're the ones with clean infrastructure, verified numbers, and documented processes.

## Next Steps

Series A preparation is comprehensive, and we've found that the most successful founders get expert perspective on their financial infrastructure and operational readiness before they start fundraising.
