A business can show a profit on paper and still be unable to pay salaries next week. That gap between profit and cash is behind most cash flow trouble, and it usually comes from a few repeated habits, not from bad luck.
Below are four mistakes that cause the most damage, why each one happens, and what to do about it. The examples use made-up numbers to show the logic, so replace them with your own.
1. Treating profit as if it were cash
Profit is what is left after subtracting expenses from sales. Cash is what is actually in your bank account today. They differ because of timing. You may invoice ₹5 lakh in March, but if the customer pays in May, that revenue helps your profit statement and does nothing for your bank balance in April.
An illustrative example: A small print shop completes a ₹2,00,000 order and buys ₹1,20,000 of paper and ink on the same day. On paper it made ₹80,000. If the client pays after 60 days, the shop has been ₹1,20,000 short for two months, and its rent and wages still fall due.
What to do instead
- Keep a simple 13-week cash forecast. List expected receipts and payments week by week, based on when money will actually move, not when invoices are raised.
- Update it every week. A forecast you revisit only once a quarter cannot warn you in time.
- Look at your bank balance and your forecast before agreeing to large purchases, not only your profit figure.

2. Being slow or casual about collecting money
Late invoices and loose follow-up are the most common reason a healthy business runs short. The problem is often not that customers refuse to pay. It is that nobody owns the job of asking.
Common patterns:
- Sending invoices days or weeks after the work is done
- Vague terms such as “pay soon” instead of a due date
- No reminder until the invoice is already badly overdue
- Offering long credit to one big customer because they are “reliable”
What helps in practice
- Invoice on the day of delivery, or bill a deposit or milestone payment upfront for larger jobs.
- Put a specific due date on every invoice, not just “net 30.”
- Set a reminder routine, for example a polite message two days before the due date, one on the day, and a call a week after.
- Track which customers consistently pay late, and shorten their terms or ask for advance payment.
A quick worked comparison (hypothetical):
| Terms as written | Actual customer behaviour | |
|---|---|---|
| Invoice amount | ₹2,00,000 | ₹2,00,000 |
| Due | Day 30 | Paid on Day 60 |
| Cash gap | None | 30 extra days you must fund yourself |
That 30-day gap is real money you have to finance from savings, an overdraft, or by delaying your own bills.
3. Running with almost no cash cushion
Even good cash management cannot help if there is no buffer for a slow month, a delayed payment, or an unexpected repair.
Researchers at the JPMorgan Chase Institute studied cash data from about 597,000 US small businesses and found that half of all small businesses hold a cash buffer large enough to support only 27 days of their typical outflows. It also varies a lot by sector: small restaurants held the fewest buffer days on average (16), while real estate businesses held the most (47). The same research found that 25 percent of small businesses held 13 buffer days or fewer. This is US data from 2015, so treat it as a rough benchmark rather than a rule for an Indian business, but the pattern is a useful warning.

How to calculate your own buffer
The Institute’s measure is simple: cash balance divided by daily cash outflows gives you the number of buffer days. JPMorgan Chase
Illustrative example: If your monthly spending is ₹4,00,000 (about ₹13,300 a day) and you hold ₹6,00,000 in the bank, you have roughly 45 days of cover.
Practical steps
- Work out your current number before deciding on a target. Your industry matters. A business with heavy payroll and thin margins will naturally hold fewer days than one with high margins.
- Build the reserve in small, fixed amounts, for instance by moving a set percentage of each payment received into a separate account.
- If you plan to use a credit line as backup, arrange it while your finances look healthy. It is much harder to get approved when you are already short.

4. Getting the timing of supplier payments wrong
This mistake runs in two directions, and both hurt.
Paying too early. Clearing every supplier bill the moment it arrives, even when the terms give you 30 days, drains cash that could be sitting in your account.
Paying too late, especially in India. Since April 2024, Section 43B(h) of the Income Tax Act has tied tax deductions to how quickly you pay micro and small enterprise (MSE) suppliers. If a payment to an MSE goes beyond the limit set in Section 15 of the MSMED Act, the deduction is allowed only in the year the payment is actually made. The time limit is 15 days if there is no written agreement, or the agreed period (maximum 45 days) if there is one.
So a 60-day credit term written into a contract does not protect you from this rule. The consequence is a higher tax bill for the year, plus compound interest at three times the RBI-notified bank rate on late payments under the MSMED Act.
Two details worth knowing:
- The rule applies to micro and small suppliers with valid Udyam registration, not to medium enterprises.
- Reports indicate the same rule carries into the new Income Tax Act, 2025 under a different section number (37(2)(g)), effective from FY 2026-27. Confirm the current section reference with your chartered accountant.
What to do
- Tag each supplier in your accounts as micro, small, medium or unregistered. Ask suppliers for their Udyam number.
- Set a payment calendar so MSE suppliers are paid within the legal limit, and other suppliers are paid on their due date, not earlier.
- Review outstanding MSE payables well before 31 March each year.

Frequently asked questions
How often should I review my cash flow?
Weekly for a forecast of the next 13 weeks is a sensible habit for most small businesses. Businesses with very tight margins or seasonal swings may want to check even more often.
Is a profitable business safe from cash problems?
No. A profitable business can still run out of cash if customers pay slowly or if money is tied up in stock and unpaid invoices.
What is a healthy cash buffer?
There is no single figure. It depends on your industry, payment cycles and fixed costs. Calculating your own buffer days, as shown above, is more useful than copying a generic target.
Conclusion
Most cash flow problems come down to timing: when money arrives, when it leaves, and how much cushion sits in between. Start with one action this week. Build the 13-week forecast, or calculate your buffer days. Either will show you where the pressure sits, and that tells you which of the four mistakes to fix first.
Editorial notes
Verified from sources:
- JPMorgan Chase Institute figures (27 days, 16 vs 47 days, 13 days) come from the Institute’s own report and press release: jpmorganchase.com/institute
- Section 43B(h) details (15/45 days, effective April 2024, MSE only, interest at 3x bank rate) are consistent across multiple Indian tax-advisory sources. These are secondary sources, so please have your CA confirm the final wording against the Income Tax Act / MSMED Act before publishing.
Deliberately left out because I couldn’t verify the original source:
- The widely repeated “82% of businesses fail due to cash flow” claim. It circulates without a clear primary source.
- Statistics from the Federal Reserve and Intuit surveys. They appeared only through a secondary blog, so include them only after checking the original reports.
Suggested additions from your side:
- Real examples from your own clients or experience, if you have any. That is what will make the article feel genuinely yours.
- Internal links to relevant pages on your site (invoicing, GST, working capital), only where they fit naturally.
- A backlink, if you have one to place, works best in Mistake 3 (credit line or buffer) or Mistake 2 (invoicing tools).
