Every founder learns this lesson at least once, usually painfully. You close a big deal. P&L shows a great month. Then 30 days later, the customer hasn't paid yet, payroll is due, the GST filing is overdue, and you're scrambling to a relative for a short-term loan.
Profit and cash are different things. Most small-business education focuses on profit. Most small-business deaths come from cash.

The difference, in 30 seconds
- P&L (profit and loss) — what you earned minus what you spent, regardless of when money actually moved. Accrual basis. Long-term story.
- Cash flow — what money actually entered and left your bank account this period. When the cheque cleared or the bill got paid. Short-term reality.
- A business with ₹1L profit but ₹5L overdue receivables and ₹3L upcoming payables is cash-poor and at risk — even though P&L looks 'fine'.

The four things that wreck SMB cash
- Slow-paying customers. B2B clients on 45-90 day terms while you pay vendors weekly. Working capital eats you.
- Inventory tied up. Bought stock 3 months ago, hasn't sold yet. Cash is in cardboard boxes, not your bank.
- Big upfront costs. Office deposit, fitout, equipment — paid upfront but earning over 12-24 months.
- Founder withdrawals timed wrong. Personal expenses on bad months wreck operating cash.

Five practical cash discipline rules
Things you can do this week that compound for years.
- 1
1. Invoice the day you deliver
Not the end of the month. Not 'when I get around to it'. Same-day invoicing reduces collection time by an average of 7-10 days.
- 2
2. Negotiate shorter payment terms upfront
Net-15 vs Net-30 vs Net-60 makes a massive working-capital difference. Push for shorter, sweeten with a 1-2% early-payment discount if needed. Many small accounts agree.
- 3
3. Collect advance from new customers
20-50% upfront, balance on delivery. Standard in service businesses. Filters bad customers AND funds your work. Don't apologise for asking.
- 4
4. Pay vendors monthly, not weekly
Match your collection cycle to your payment cycle. If you collect monthly, pay monthly. If you pay weekly, you're financing your customers.
- 5
5. Keep 60-90 days operating cash in reserve
Untouchable. Separate account if you have the discipline. Not for growth — for surviving the bad quarter that always comes.

The 13-week cash forecast
Excel sheet. 13 columns (one per upcoming week). 5 rows: opening balance, expected inflows, expected outflows, net flow, closing balance. Update weekly.
This isn't accounting — it's planning. You see the cash dip three weeks before it hits. You know to call that slow-paying customer NOW. You delay the new hire by one month if needed. The forecast is the early-warning system that prevents emergencies.

When P&L matters more
Don't take this article as 'cash is the only thing that matters'. Long-term, P&L is the actual business model. If you're cash-positive but margin-negative (you collect upfront but spend more than you collect over time), you'll run out eventually. Cash discipline buys you time; P&L discipline buys you forever.
Both. Always. In a crunch, cash wins. In planning, P&L wins. Run a business long enough and you'll need both reflexes.
Profit pays in three years. Cash pays in three weeks. Most small businesses don't survive long enough to see profit if they don't manage cash. Discipline the cash side first. P&L is the prize at the end.
