Understanding Basics:
Cash runway is how long your business can survive on current cash reserves. It accounts for the gap between what's coming in and going out each month. A positive burn rate means you're spending more than you earn.
Benefits for SMEs:
- Avoid cash surprises before they become crises
- Make informed decisions about timing of major purchases
- Know when to chase receivables more aggressively
- Plan ahead for seasonal slow periods
