One of the hardest lessons for new founders is that profit and cash are not the same thing. A business can be profitable on paper and still fail because it can't meet payroll. Managing cash flow is survival.
Watch timing, not just totals
Revenue you haven't collected can't pay your bills. Pay close attention to when money actually moves, not just what the ledger says.
Build a buffer
Every business hits a rough patch. A cash reserve turns a crisis into an inconvenience.
Know your numbers cold
The founders who survive downturns are the ones who understand their financials intimately and can act before a problem becomes fatal.
