Finance & Accounting
Core Principle
Cash is oxygen. You don't need perfect books — you need to know exactly when the money runs out and what levers you can pull.
Burn Rate Analysis
Gross vs. Net Burn
GROSS BURN = Total monthly expenses (all cash out the door)
NET BURN = Total expenses - Total revenue (actual cash drain)
Example:
Monthly expenses: $80K
Monthly revenue: $30K
Gross burn: $80K
Net burn: $50K
Track both. Gross burn shows cost structure. Net burn shows survival math.
Burn Rate Breakdown Template
| Category | Monthly $ | % of Burn | Notes |
|---|
| Salaries & benefits | | | Largest line — typically 60-75% |
| Infrastructure (AWS, tools) | | | Should scale with revenue |
| Office / remote stipends | | | Fixed cost |
| Marketing & sales | | | Variable — should generate ROI |
| Legal & accounting | | | Often underestimated |
| Misc / buffer | | | 5-10% of total |
| Total Gross Burn | | 100% | |
Runway Calculations
Basic Runway
Runway (months) = Cash in bank / Net monthly burn
Example:
Cash: $500K
Net burn: $50K/mo
Runway: 10 months
Adjusted Runway (with growth)
If revenue is growing, runway is longer than simple division suggests.
Month 1: $500K - ($80K - $30K) = $450K
Month 2: $450K - ($80K - $33K) = $403K (10% MoM revenue growth)
Month 3: $403K - ($80K - $36K) = $359K
...
Model month-by-month. The spreadsheet matters more than the formula.
Runway Decision Triggers
12+ months: Comfortable. Focus on growth.
9 months: Start fundraising prep. Update deck and data room.
6 months: ACTIVELY fundraising or cutting costs. No other priority.
3 months: Emergency mode. Cut to essentials. Bridge or pivot.
Cash Flow Forecasting
13-Week Cash Flow Template
Week | Starting Cash | Cash In | Cash Out | Ending Cash | Notes
-----|---------------|---------|----------|-------------|------
W1 | $500K | $12K | $18K | $494K |
W2 | $494K | $8K | $20K | $482K | Payroll
W3 | $482K | $15K | $12K | $485K |
W4 | $485K | $10K | $35K | $460K | Annual tool renewal
...
Cash Flow Forecasting Rules
1. Revenue: Use conservative estimates (80% of expected)
2. Expenses: Use aggressive estimates (110% of expected)
3. Timing: Model when cash ACTUALLY moves, not when it's invoiced
4. Seasonality: Note months with unusual patterns (annual contracts, tax)
5. Update weekly: Forecasts are only useful if they're current
Monthly Close Template
Close Checklist (Target: Complete by 10th of following month)
WEEK 1 (Days 1-5):
- [ ] Reconcile all bank accounts
- [ ] Reconcile credit card statements
- [ ] Categorize all transactions
- [ ] Record revenue (recognized, not just invoiced)
- [ ] Record payroll and benefits
WEEK 2 (Days 5-10):
- [ ] Review accounts receivable aging
- [ ] Reconcile accounts payable
- [ ] Review prepaid expenses and amortization
- [ ] Generate P&L, Balance Sheet, Cash Flow Statement
- [ ] Compare actuals to budget — note variances > 10%
- [ ] Update runway forecast
Three Financial Statements to Know
P&L (Profit & Loss / Income Statement)
→ Are we making or losing money? How much?
→ Revenue - COGS = Gross Profit - OpEx = Net Income
Balance Sheet
→ What do we own (assets) vs. owe (liabilities)?
→ Assets = Liabilities + Equity
Cash Flow Statement
→ Where did cash actually go?
→ Operating + Investing + Financing = Net Cash Change
When to Hire Finance Help
Decision Matrix
| Stage | Action | When |
|---|
| Pre-seed / bootstrapping | Founder does books + QuickBooks | $0-$25K MRR |
| Seed | Bookkeeper (part-time or outsourced) | $25K-$100K MRR |
| Series A | Controller or outsourced CFO | $100K-$500K MRR |
| Series B+ | Full-time CFO | $500K+ MRR or complex financials |
Signs You Need Help Now
- You're more than 2 months behind on reconciliation
- You can't answer "what's our burn rate?" in under 60 seconds
- You're preparing for fundraising and need clean financials
- You have more than 50 customers and complex invoicing
- Tax filing gives you anxiety because the books aren't ready
Anti-Patterns
| Finance Theater | Real Finance |
|---|
| "We'll figure out the books later" | Monthly close from month 1 |
| Checking bank balance = financial management | P&L + runway forecast updated monthly |
| Mixing personal and business accounts | Separate accounts from day 1 |
| Revenue = cash received | Revenue = value delivered (accrual accounting) |
| Ignoring burn until fundraising | Weekly burn awareness, monthly reporting |
