Profitable businesses fail when they run out of cash. Managing timing between money in and out is critical.
Forecast regularly
Build a 13-week cash flow forecast listing expected receipts and payments by week. Update it weekly. It reveals gaps early enough to act.
Speed up cash in, slow cash out
Invoice promptly, offer early-payment discounts, require deposits and use automatic reminders. On the payables side, negotiate terms and pay on due dates rather than early unless a discount justifies it.
Build a buffer
Aim for at least three to six months of operating expenses in reserve. Arrange a line of credit before you need it. Watch runway, the number of months until cash runs out at the current burn rate.
Try the numbers
Use our Cash Runway Calculator to see this in practice. With its default example (Cash on hand: $180,000; Monthly expenses: $32,000; Monthly revenue: $14,000), it shows runway: 13 months. Adjust the inputs to match your situation.
Key takeaways
- Profit and cash are different things.
- Forecast weekly and update often.
- Hold a cash reserve and arrange credit early.
