Quick answer

Startup accounting made practical: clean foundations, runway visibility, receivables, payables control, and investor-ready reporting.

  • Set up clean foundations early: separate finances and a simple chart of accounts.
  • Track burn and runway with current reports so you can make fast decisions.
  • Send invoices promptly and monitor AR aging to protect cash flow.
  • Track vendor bills as they arrive so AP doesn’t surprise you later.
  • Reconcile monthly and review P&L, Balance Sheet, and Trial Balance consistently.

Startup accounting is about building clean financials early so you can make good decisions, understand runway, and avoid painful cleanup later. Simple processes and consistent reporting matter more than complexity.

1. Set up clean foundations

Separate business and personal finances immediately. Create a basic chart of accounts that matches how you operate (revenue, payroll/contractors, software/tools, marketing, travel, and general overhead).

2. Track runway and burn

Runway is a simple question: how long can you operate at your current burn rate? Even early on, keep reports current so you can see cash position and monthly spend clearly.

3. Keep invoices and receivables tight

If you invoice customers, send invoices promptly, track payments, and monitor accounts receivable aging. Slow collections can kill early cash flow.

4. Control accounts payable

Track vendor bills as they arrive so you know what’s due and when. A clean AP process prevents surprises and helps you manage cash deliberately.

5. Reconcile monthly and review reports

Reconcile bank activity monthly, then review P&L, Balance Sheet, and Trial Balance. These reports become your baseline for forecasting and investor readiness.

FAQ

Keep cash current, measure monthly burn, and estimate months of cash remaining at the current rate.
