model, clearly defined growth metrics, a clean cap table, current tax filings and 409A valuations, an organized data room and a use-of-funds plan tied to specific milestones. Completing these steps before the first investor meeting shortens due diligence and strengthens the founder's negotiating position.
Seed-stage companies can often get by with simple bookkeeping and a pitch deck built on momentum. Series A is different. Institutional investors are writing larger checks, and their diligence teams will examine the financials line by line. They want to know that revenue is recognized properly, that growth metrics hold up under scrutiny, and that the company knows exactly how it will use the new capital. startup financial planning consulting
Founders who wait until a term sheet is on the table to clean up their finances often pay for it in delays, renegotiated terms or deals that stall altogether. That's why many companies begin working with startup financial planning consulting partners six to twelve months before they plan to raise. The goal is to make the diligence process confirm the story the founder is already telling.
This checklist walks through what to prepare, why it matters and how to get it done.
Why Series A Diligence Feels So Different
Definition: Financial due diligence is the process investors use to verify a company's financial records, metrics, obligations and projections before committing capital. It typically covers accounting quality, revenue, expenses, cash, taxes, equity and legal agreements.
At the seed stage, investors often bet heavily on the team and the idea. By Series A, they are underwriting a business. They expect evidence of repeatable growth, efficient use of capital and financial controls strong enough to support a much larger company.
Diligence also tends to move quickly once it starts. Requests arrive in batches, and every day spent searching for a missing contract or reconciling a revenue figure is a day the deal is not closing. Preparation turns a stressful scramble into a straightforward review.
Step 1: Move to Accrual-Based, Investor-Grade Books
Many early startups use cash-basis accounting, recording revenue when payment arrives and expenses when bills are paid. Institutional investors generally expect accrual-based statements that follow generally accepted accounting principles (GAAP).
Key actions:
● Convert to accrual accounting so revenue and expenses land in the period they were earned or incurred
● Recognize revenue correctly, especially for annual prepaid contracts, which should be recognized over the service period
● Record deferred revenue as a liability on the balance sheet
● Book accrued expenses for services received but not yet invoiced
● Capitalize and depreciate qualifying equipment rather than expensing it all at once
● Separate personal and business expenses completely
It also helps to restate at least the prior 12 to 24 months on an accrual basis, so investors can review a consistent history rather than a mix of methods.
Step 2: Build a Reliable Monthly Close
A monthly close is the routine of reconciling accounts, reviewing transactions and finalizing financial statements for the month. Investors see a consistent close as a signal that leadership is working from current, trustworthy numbers.
A strong close process includes:
- Bank and credit card reconciliations completed every month
- Review of accounts receivable and payable for accuracy and aging
- Payroll and benefits entries matched to provider reports
- Revenue reconciliation between billing systems and the general ledger
- Budget-to-actual comparison with explanations for major variances
- Final statements delivered within a set number of days after month-end
If financial statements currently take six weeks to finalize, shortening that timeline is one of the most valuable improvements a founder can make before raising.
Step 3: Create a Financial Model Investors Can Stress-Test
Series A investors will want a three-statement model covering the income statement, balance sheet and cash flow statement, usually projected monthly for 24 to 36 months.
What separates a credible model from a hopeful one:
● Driver-based assumptions, such as sales hires, conversion rates, pricing and churn, rather than a simple growth percentage
● Historical actuals connected to projections, so investors can see how the forecast builds from real results
● Headcount planning by role and start date, since people are usually the largest expense
● Multiple scenarios, including base, upside and conservative cases
● A clear link between capital raised and milestones reached
Investors will change assumptions to see what happens. A model that breaks or produces unrealistic results when adjusted undermines confidence quickly.
Step 4: Define and Document Your Core Metrics
Metrics are central to Series A conversations, and definitions matter as much as the numbers themselves.
For software businesses, investors typically focus on annual recurring revenue, net and gross revenue retention, gross margin, customer acquisition cost, payback period and burn multiple. Founders who work with CFO services for SaaS startups often build a metrics package that ties every figure back to the financial statements, which prevents discrepancies from surfacing during diligence.
Companies in other sectors will emphasize different measures, such as contribution margin and repeat purchase rate for consumer brands, or gross margin and sales velocity for hardware companies. Whatever the model, founders should:
● Write down the definition of every metric in a one-page glossary
● Keep the calculation consistent across the deck, model and data room
● Show at least 12 to 24 months of monthly history
● Break results out by cohort, segment or channel where it adds insight
● Disclose unusual events, such as a large customer loss or one-time spike, before investors find them
Step 5: Clean Up the Cap Table and Equity Records
Cap table problems are among the most common causes of Series A delays. Investors need to know exactly who owns what, and how the round will change it.
Review the following carefully:
● All issued shares match board approvals and stock certificates or ledger entries
● Convertible instruments, such as SAFEs and convertible notes, are documented with their caps, discounts and conversion terms
● Option pool size and grants are recorded accurately, with vesting schedules up to date
● 409A valuations are current, since option grants should generally be priced at or above fair market value
● Founder vesting and any 83(b) elections are documented
● A pro forma cap table models how the new round and any pool expansion will affect ownership
Using cap table management software rather than a spreadsheet can reduce errors and make investor review much easier.
Step 6: Confirm Tax Compliance and Capture Available Credits
Tax issues can create unexpected liabilities that investors will want resolved before closing. Common items to review include:
● Federal and state income tax returns filed for every required year
● State franchise taxes and annual reports, including those in the state of incorporation
● Payroll tax filings for employees in every state where the company has staff
● Sales tax obligations, particularly for companies selling across state lines
● Contractor classification, to avoid misclassification risk
● Required information returns, such as 1099 filings
This is also the right time to review eligibility for the federal R&D tax credit. Many startups building software, products or new processes qualify, and qualified small businesses that are not yet profitable may be able to apply the credit against payroll taxes. That can extend runway and reduce how much capital the company needs to raise.
Step 7: Organize the Data Room Before Anyone Asks
A well-organized data room shows investors that the company runs with discipline.
Folder Typical Contents
Corporate Certificate of incorporation, bylaws, board minutes and consents
Financial Monthly and annual financial statements, financial model, budget
Metrics KPI dashboard, metric definitions, cohort analysis
Equity Cap table, pro forma cap table, SAFEs and notes, option plan, 409A reports
Customers and revenue Top customer contracts, pricing, revenue by customer
Team Org chart, employment agreements, contractor agreements, IP assignments
Tax Federal and state returns, payroll and sales tax filings
Legal and IP Material contracts, patents, trademarks, any litigation
Keeping the data room current, updating financials and metrics monthly, also shows investors that the business is moving forward during the process.
Step 8: Prepare a Use-of-Funds and Runway Plan
Investors want to understand exactly what their capital will accomplish. A clear use-of-funds plan should connect the raise to hiring, product development, marketing, operations and a cash reserve, and show which milestones the company expects to reach before its next round.
Tie the plan to runway. If the raise is expected to last a certain number of months, show how burn will change as new hires join and revenue grows. Investors are more comfortable when founders have planned for delays and know which levers they can pull if growth arrives more slowly than expected.
Step 9: Put Board-Level Reporting in Place
After Series A, most companies add investor representation to the board. Starting a board-style reporting rhythm before the raise makes that transition easier.
A strong monthly or quarterly update typically includes financial statements, budget-to-actual results, key metrics, cash position and runway, major wins and risks, and upcoming decisions. Founders who already report this way demonstrate that they are ready to manage a larger company and a more formal governance structure.
Many early-stage leaders find this level of financial management difficult to build alone. Advisory firms that focus on financial strategy for small businesses and venture-backed startups can help set up reporting, strengthen controls and prepare leadership for the scrutiny that comes with institutional capital.

Founder FAQ: Getting Finance-Ready for Series A
How early should founders start preparing for Series A diligence?
Ideally six to twelve months before the raise. Converting to accrual accounting, restating history and cleaning up equity records all take time.
Do investors require audited financial statements for a Series A?
Not always. Many Series A investors accept well-prepared, reviewed or internally prepared accrual statements, though some may require audits, and audits often become necessary in later rounds.
What is the most common financial issue that delays a round?
Cap table errors and inconsistent metrics are frequent culprits, along with revenue recognition problems in companies that sell annual contracts.
Should a startup hire a full-time CFO before Series A?
Many companies don't need one yet. Fractional or outsourced CFO support can provide investor-grade reporting and fundraising help at a lower cost, with a full-time hire often coming later.
Walking Into the Raise Prepared
A Series A is a turning point, and the founders who navigate it best are the ones who treat financial readiness as part of the fundraising strategy rather than an afterthought. Clean books, a credible model, well-defined metrics, an accurate cap table, current tax filings and an organized data room let investors spend their time evaluating the opportunity instead of questioning the numbers. With an experienced partner like K-38 Consulting helping prepare the foundation, founders can enter diligence with confidence and close their round on stronger terms.
