Month-End Financial Checklist for Founders
Seed-stage founders who close books within 5 days make faster decisions. Use this 22-item checklist to close your month-end in half the time.
Seed-stage founders who close their books within 5 business days of month-end make measurably faster and better financial decisions than those who take 15+ days. The reason is simple: stale data leads to stale decisions. If you are looking at February's numbers on March 20th, you have already spent three weeks operating blind.
Most founders dread the month-end close because it is an unstructured mess of bank logins, spreadsheet updates, and vague anxiety about whether the numbers are right. A structured checklist fixes this. It turns an ambiguous, multi-day slog into a repeatable process you can complete in 4-6 hours.
This checklist is designed for seed-stage to Series A founders -- the stage where you are probably doing this yourself or with one part-time bookkeeper. Adapt it as your team and complexity grow.
The 22-Item Month-End Checklist
Phase 1: Data Collection (Day 1)
1. Download Bank Statements
Pull statements for all business bank accounts for the completed month. Verify ending balances match your online banking.
Common mistake: Forgetting secondary accounts (savings, money market, PayPal, Stripe balance).
2. Download Credit Card Statements
Pull all business credit card statements. Match every charge to a receipt or vendor.
3. Pull Payment Processor Reports
Download settlement reports from Stripe, PayPal, or other payment processors. These show:
- Gross revenue collected
- Fees deducted
- Net deposits to your bank account
- Refunds and chargebacks
4. Collect Outstanding Invoices
List all invoices sent but not yet paid. Update the AR aging report. Flag anything over 30 days.
5. Gather Expense Receipts
Collect any missing receipts for the month. Set a policy: no receipt, no reimbursement. For business card charges, match each transaction to documentation.
Phase 2: Reconciliation (Day 1-2)
6. Reconcile Bank Accounts
Match every transaction in your accounting system to your bank statement. Investigate and resolve any discrepancies.
Target: Zero unreconciled items. If you have items you cannot identify, flag them and set a 48-hour deadline to resolve.
7. Reconcile Credit Cards
Same process as bank reconciliation. Match every charge. Categorize any that are still uncategorized.
8. Reconcile Payment Processor to Revenue
Verify that the revenue in your accounting system matches what your payment processor reports. Common discrepancies:
- Processing fees not recorded
- Refunds not reflected
- Currency conversion differences
- Timing differences (payment received last day of month, deposited first day of next)
9. Reconcile Payroll
Verify payroll entries match your payroll provider's reports. Check:
- Gross wages
- Employer taxes (FICA, FUTA, state)
- Benefits deductions
- Net pay deposited
Payroll is typically 65-75% of a startup's total expenses. Getting this wrong distorts your entire P&L. For context on what a healthy P&L looks like at your stage, see healthy monthly P&L benchmarks for seed-stage startups.
Phase 3: Adjustments (Day 2-3)
10. Record Accrued Expenses
Book expenses that were incurred during the month but not yet paid:
- Accrued payroll (pay periods that span month-end)
- Accrued contractor invoices
- Accrued professional services
- Accrued interest on loans
11. Amortize Prepaid Expenses
If you prepaid for annual subscriptions, insurance, or other multi-month costs, book the monthly amortization:
| Prepaid Item | Annual Cost | Monthly Amortization |
|---|---|---|
| Business insurance | $12,000 | $1,000 |
| Annual software licenses | $24,000 | $2,000 |
| Prepaid rent | $96,000 | $8,000 |
12. Record Depreciation
If you have fixed assets (computers, equipment, furniture), book monthly depreciation. For most startups, this is a small amount but should not be skipped.
13. Recognize Revenue Correctly
For SaaS companies with annual or multi-month contracts:
- Recognize only the portion of revenue earned this month
- Defer the remainder as deferred revenue on the balance sheet
14. Record Any Unusual Items
Journal entries for non-routine items:
- Write-offs of bad debt
- Disposal of assets
- One-time legal or settlement costs
- Foreign exchange gains/losses
Phase 4: Review and Validation (Day 3-4)
15. Generate Draft Financial Statements
Pull your three core reports:
- Income Statement (P&L): Revenue minus expenses equals net income
- Balance Sheet: Assets equal liabilities plus equity
- Cash Flow Statement: Explains the change in cash balance
16. Run Budget vs. Actual Comparison
Compare every P&L line item to your budget. Flag variances over 10%.
| Category | Budget | Actual | Variance | % |
|---|---|---|---|---|
| Revenue | $55,000 | $52,000 | ($3,000) | -5.5% |
| Payroll | $72,000 | $75,000 | $3,000 | +4.2% |
| Marketing | $12,000 | $14,500 | $2,500 | +20.8% |
| Cloud/Hosting | $6,000 | $6,200 | $200 | +3.3% |
Use a budget accuracy scorecard to track your forecasting accuracy over time. Consistent misses in the same direction reveal systematic problems in your planning.
17. Analyze Month-Over-Month Trends
Compare this month to last month. Look for:
- Revenue growth or decline
- Expense categories that changed significantly
- Margin changes
- New expense categories that appeared
18. Calculate Key Metrics
Update your monthly metrics tracker:
| Metric | This Month | Last Month | Trend |
|---|---|---|---|
| MRR | |||
| Net burn | |||
| Runway (months) | |||
| Gross margin | |||
| CAC | |||
| Customer count |
Track your burn rate with a burn rate calculator to get instant runway projections based on your actual spending.
19. Verify Balance Sheet Balances
Check that key balance sheet items are reasonable:
- Cash matches bank statements
- AR matches outstanding invoices
- AP matches unpaid bills
- Deferred revenue matches unearned contract value
- Loan balances match lender statements
20. Review for Errors and Anomalies
Scan for common errors:
- Duplicate entries
- Transactions in wrong accounts
- Missing entries
- Incorrect dates (transactions booked in wrong month)
- Unusual amounts (extra zeros, decimal errors)
Phase 5: Close and Distribute (Day 4-5)
21. Lock the Period
Once everything is verified, lock the completed month in your accounting system. This prevents accidental changes to historical data.
22. Distribute Reports
Send the appropriate reports to stakeholders:
- Yourself: Full financial package with metrics
- Co-founders/leadership: P&L, cash position, key metrics
- Board/investors: Monthly update with narrative (if applicable)
- Bookkeeper/accountant: Reconciliation summary for review
Checklist by Company Stage
Pre-Seed (1-3 People)
Focus on items 1-9 and 15-18. Skip formal accruals, depreciation, and balance sheet verification. Your priority is accurate cash tracking and basic P&L.
Time: 2-3 hours
Seed (4-15 People)
Complete all 22 items. You may need a part-time bookkeeper to help with reconciliation and accruals.
Time: 4-6 hours
Series A (15-50 People)
All 22 items plus:
- Department-level budget vs. actual
- Revenue recognition review by a controller
- Intercompany transactions (if applicable)
- Board report preparation
Time: 8-12 hours (with finance team support)
Timing Your Close
| Day | Phase | Activities |
|---|---|---|
| Business Day 1 | Data Collection | Items 1-5 |
| Business Day 2 | Reconciliation | Items 6-9 |
| Business Day 3 | Adjustments | Items 10-14 |
| Business Day 4 | Review | Items 15-20 |
| Business Day 5 | Close | Items 21-22 |
If you are consistently finishing in 3 days, great. If it is taking more than 7, identify the bottleneck -- it is usually reconciliation or chasing missing receipts.
FAQ
What if I find an error in a previous month?
Record an adjusting entry in the current month that corrects the error. Note the original month and reason in the journal entry description. Do not go back and change locked periods unless the error is material (more than 5% of monthly revenue).
Can I skip months and do quarterly closes instead?
Technically yes, but it is not recommended. Quarterly closes take 3x longer per session because you are reconciling 3 months of transactions at once, and errors are harder to find. Monthly closes build a habit that keeps you informed and prevents problems from compounding.
What is the minimum a pre-revenue startup needs to do?
At minimum: reconcile your bank account, categorize all transactions, and calculate your monthly burn rate and remaining runway. This takes under an hour and is non-negotiable even if you have zero revenue.
