# Series A Preparation: The Financial Operations Audit Founders Skip
When we work with founders preparing for Series A, they typically come to us with three concerns: the pitch, the metrics, and the story. What they rarely mention is this: **investors spend more time auditing your operational infrastructure than evaluating your business model.**
We've watched founders nail their pitch, demonstrate impressive growth metrics, and still struggle through diligence because their financial operations fell apart under scrutiny. A $2M ARR company with scattered accounting records, undocumented vendor agreements, and no financial controls doesn't look like a growth story to investors—it looks like operational risk.
This is the side of series a preparation that nobody talks about, but diligence professionals ask about in every single deal.
## The Hidden Audit: What Diligence Teams Actually Investigate
Here's what happens in Series A diligence that founders don't see coming: after 3-4 weeks of your pitch, investors bring in their finance team. While you're focused on demonstrating product-market fit, they're investigating whether your company can actually *execute* on its growth plan from an operational standpoint.
They're not just looking at your revenue. They're asking:
- **Can you close your books in 10 days?** (Most early-stage companies can't)
- **Do you have segregation of duties?** (Can your finance person override a payment without approval?)
- **Are your vendor contracts documented?** (What happens if a critical vendor is acquired?)
- **Is your revenue recognition policy consistent with your accounting platform?** (Are you recognizing revenue correctly?)
- **Do you have month-over-month variance explanations?** (Or just raw numbers?)
- **Who owns your accounting passwords and systems?** (What if someone leaves?)
These aren't gotcha questions. They're signs that your company can scale without burning up in chaos during aggressive growth.
In our work with Series A startups, we've seen otherwise-promising companies stumble because their operations couldn't support the claims in their model. One SaaS founder had 45% YoY growth but couldn't explain why their cash flow didn't match their revenue because revenue was being recognized across three different systems. Another had a key vendor agreement that was never formally documented—just a handshake and emails—which created massive risk.
These aren't fatal flaws, but they eat diligence time, create friction with investors, and signal immaturity.
## The Financial Operations Audit: Your Series A Preparation Checklist
### 1. **Accounting Infrastructure: Can You Close Your Books Reliably?**
The first question: how long does it take you to close each month? If the answer is "3-4 weeks" or "we're not really sure," you have an infrastructure problem.
Series A investors expect companies to close by day 10 of the following month. This isn't arbitrary. It signals that:
- You have documented processes
- Someone owns each step
- Variance is investigated (not ignored)
- Your financial statements actually mean something
What diligence typically audits:
- **Chart of accounts structure**: Is it organized by business function or just random? Does it match your financial model?
- **Reconciliation process**: Are your bank accounts, credit cards, and accounting platform all reconciled monthly? Are reconciliations documented?
- **Revenue recognition**: Is your policy formally documented and aligned with how you're actually recognizing revenue in your platform?
- **Journal entry documentation**: Do you require supporting documentation for manual entries? Who approves them?
- **Accruals and reserves**: Are you properly accruing expenses? Are bad debts or refunds reserved for?
We often find that the fastest way to improve closure speed is to audit your *existing* process, not rebuild it. Usually, the delays aren't in the accounting—they're in waiting for information from operations or sales.
### 2. **Vendor Contracts and Commitments: The Unquantified Liability**
Here's something that catches founders off guard: investors want documentation for *all* material contracts, including vendor agreements.
Why? Because a casual software license deal or a vendor agreement with price escalation clauses represents real liability that affects your unit economics.
For each vendor representing >2% of your monthly burn, you should have:
- **Signed contract** (or email chain with clear terms if a formal contract doesn't exist)
- **Payment terms and duration** (annual commitment? Month-to-month?)
- **Price escalation clauses** (does the cost go up?)
- **Termination provisions** (can you leave?)
- **Data rights and security** (who owns the data?)
One founder we worked with discovered during Series A prep that a "$15k/month" vendor agreement actually had a 3-year commitment with a 10% annual price increase built in. Over the 3-year life of the contract, that was $600k in committed spend—but it was never modeled into their financial projections.
Vendors to audit:
- Cloud infrastructure (AWS, GCP, Azure)
- Payment processors (Stripe, etc.)
- Third-party APIs and integrations
- Insurance and SaaS tools
- Hosting and CDN
- Any custom development or outsourced services
Create a **vendor commitment schedule** that lists each major contract, annual commitment, and renewal date. This becomes part of your data room and answers the "what are we locked into?" question before diligence asks it.
### 3. **Financial Controls: Can Your Finance Person Actually Control Anything?**
This is the uncomfortable one, but it matters: do you have financial controls, or do you have chaos with good intentions?
In early stage, founders often control most financial decisions personally. But as you grow, you need documented controls that don't depend on the founder catching every mistake.
Investors want to see evidence of:
- **Approval workflows**: Are expenses above certain thresholds approved by someone other than the requester?
- **Credit card reconciliation**: Does someone review every charge monthly?
- **Payroll review**: Who verifies that payroll is correct before it processes?
- **Expense policy**: Does your team know what they can and can't spend on?
- **Payment authorization**: Who can approve payments and above what amounts?
You don't need enterprise-grade controls, but you need *documented* controls. We've seen investors pause diligence because a founder couldn't explain how they prevent fraud—not because fraud has occurred, but because the lack of a process itself is a red flag.
Simple controls that matter:
- Monthly reconciliation of balance sheet accounts
- Credit card statement review (with sign-off)
- Bank account reconciliation
- Expense policy in writing (even if it's basic)
- Approval thresholds (e.g., "expenses over $5k require founder approval")
### 4. **Month-over-Month Variance Explanation: Can You Tell a Story About Your Numbers?**
This is where operational maturity and financial sophistication intersect.
Most founders track YoY growth and call it a day. Investors dig deeper: they want to understand *why* your CAC went up 20% last month, or why your payroll had a $40k variance.
Creating a simple **monthly variance summary** (1 page) that explains:
- Revenue variances (upside or downside)
- Expense changes >10% vs. prior month
- One-time items or adjustments
This serves two purposes: first, it forces *you* to understand your business operationally. Second, it demonstrates to investors that you're actively managing the business, not just watching metrics on a dashboard.
One founder we worked with discovered through variance analysis that his customer success team was spending 40% more time on onboarding than planned—which wasn't captured in any metric until they looked at labor costs. That insight led to a product improvement that became a key competitive differentiator.
### 5. **Data Integrity: Where Does Revenue Actually Live?**
Here's the awkward question that always comes up in diligence: **if your accounting system crashed tomorrow, could you recreate your revenue from source data?**
For most startups, the honest answer is no. Revenue exists in your billing system, but the accounting records are in a different system, and reconciliation happens manually each month.
Investors want to see:
- **Revenue source documentation**: Where does revenue originate? (Stripe, PayPal, custom billing system?)
- **Reconciliation of revenue sources to accounting**: Does your accounting system tie out to billing on a monthly basis? Are variances explained?
- **Audit trail**: Can you trace an invoice back to a contract? Back to a signature?
- **Refund and cancellation policy**: How are these handled? Is it consistent?
You don't need to rebuild your systems, but you need to **document the data flow**. Create a simple one-page diagram showing: contracts → billing system → revenue recognition → financial statements. Show how each step ties out.
### 6. **Cap Table Hygiene: Is Your Cap Table Actually Accurate?**
This should be obvious, but it's not. We've seen Series A diligence stall because the cap table had a mistake that created ambiguity about who owns what.
Your cap table should have:
- **All equity grants documented** (option grants, restricted stock awards, founder shares)
- **Vesting schedules clearly defined**
- **Strike prices and exercise prices documented**
- **All historical raises and convertible notes tracked**
- **Updated on every change** (not updated once a year)
One common mistake: founders issue equity informally ("you get 0.5% if you join") without actually documenting it until Series A prep. Then it becomes a scramble to reconstruct what was agreed verbally.
Use a tool like [CAC Benchmarking: Why Your Industry Comparison Is Misleading](/blog/cac-benchmarking-why-your-industry-comparison-is-misleading/) or even a simple spreadsheet, but keep it updated and have your investors and employees sign off on it before diligence begins.
## The Data Room: Operational Documentation That Matters
When you organize your data room (the repository of documents investors review during diligence), include an **Operations and Controls** section that contains:
- Accounting process documentation (how you close, how long it takes)
- Reconciliation templates and recent examples
- Revenue recognition policy (in writing)
- Major vendor contracts
- Expense approval policy
- Cap table with supporting documentation
- Monthly financial statements for the past 24 months
- Cash flow variance analysis (last 12 months)
This section signals sophistication and saves diligence time. Instead of asking "do you have controls?", they see the evidence directly.
## Timeline: When to Start This Audit
If you're targeting Series A in 6-12 months, you should start this operational audit **now**—not 3 months before fundraising.
- **Month 1-2**: Audit your current accounting process. Where are the delays? Where's the friction?
- **Month 2-3**: Get your vendor contracts organized and documented
- **Month 3-4**: Document your financial controls (even if they're simple)
- **Month 4-5**: Implement reconciliation and variance analysis processes
- **Month 5-6**: Prepare data room materials
This 6-month timeline gives you runway to actually improve operations instead of just documenting chaos.
## The Mistake Most Founders Make
Here's the pattern we see repeatedly: founders wait until month 3 before Series A to think about operations. Then they spend frantic weeks trying to recreate lost vendor agreements, clean up reconciliations, and document processes.
The irony? These operational improvements usually improve unit economics and cash flow management in ways that actually make your business *stronger* for investors. You're not just preparing for diligence—you're building a better-run company.
We worked with a marketplace founder who delayed implementing proper reconciliation until Series A prep. When she finally did, she discovered a $60k annual leak in refund handling that no one knew about. Fixing it improved unit economics by 8%. That improvement wasn't apparent until someone actually looked operationally.
## Preparing Your Series A Presentation: Connecting Operations to Growth
Here's something most pitch decks miss: your Series A presentation should briefly acknowledge operational excellence, not just growth metrics.
One slide that resonates: "Financial Operations Maturity" that shows:
- Book closure speed (month-end close by day X)
- Reconciliation coverage (what % of balance sheet is reconciled monthly)
- Control environment (specific controls you've implemented)
- Data integrity (how revenue ties to billing to accounting)
This slide isn't flashy, but it signals competence. Investors know that execution on growth depends on operational foundation.
