Startup Bookkeeping Best Practices: From Seed to Series A

We've seen it dozens of times: a startup is ready to raise their Series A, but their books are a mess. Due diligence stalls, investors get nervous, and the round takes months longer than necessary.

The Foundation: Chart of Accounts

Your chart of accounts (COA) should be structured for growth:

Revenue Accounts

• SaaS Revenue (MRR)
• Professional Services Revenue
• Other Revenue

Cost of Goods Sold

• Hosting & Infrastructure (AWS, GCP, Azure)
• Third-party Software in COGS
• Customer Support Costs

Operating Expenses

• Payroll & Benefits (by department)
• Rent & Facilities
• Software & Tools
• Marketing & Advertising
• Travel & Entertainment
• Legal & Professional Fees
• Insurance

Monthly Close Process

Every startup should aim for a monthly close within 15 business days of month-end:

1. Bank reconciliation: Match every transaction to a bank record
2. Credit card reconciliation: Ensure all card transactions are categorized
3. Revenue recognition: Apply ASC 606 principles (yes, even at seed stage)
4. Accruals: Record expenses incurred but not yet paid
5. Prepaid amortization: Amortize annual subscriptions monthly
6. Payroll reconciliation: Verify payroll entries match payroll reports
7. Intercompany reconciliation: For companies with Israeli subsidiaries
8. Financial review: Review P&L, balance sheet, and cash flow statement

Key Metrics to Track

Beyond basic financial statements, track:

• Burn rate: Monthly cash burn (gross and net)
• Runway: Months of cash remaining at current burn
• MRR/ARR: Monthly/annual recurring revenue
• Gross margin: Revenue minus COGS
• CAC: Customer acquisition cost
• LTV: Customer lifetime value

Common Mistakes

1. Mixing personal and business expenses: Use separate accounts from day one
2. Ignoring accrual accounting: Cash basis is fine for taxes but not for investors
3. Not tracking equity properly: Cap table management is critical
4. Forgetting sales tax: SaaS companies often have nexus in multiple states
5. Deferring cleanup: Technical debt in your books is as dangerous as in your code
