Plenty of small businesses that close down were profitable. Their accounts showed healthy margins, their order books were full, and they still couldn't pay salaries one month. The reason is simple and brutal: profit is an accounting idea, cash is what pays the bills, and the two can drift months apart.
Most cash crunches trace back to a small set of avoidable mistakes. Here are the seven we see most often, grouped by where they happen.
Mistakes in how you measure
1. Confusing profit with cash
You complete a ₹5,00,000 project in March. Your profit and loss statement records the income in March. But the client pays on 60-day terms, so the cash arrives in May — while your team's salaries, rent and software bills went out in March and April. On paper you're profitable. In the bank, you're short.
2. Running without a forecast
Many owners look at the bank balance and decide whether things feel fine. A balance tells you where you are today, not where you'll be in six weeks when the quarterly tax payment, an annual software renewal and a big supplier invoice all land together. A simple 13-week cash forecast, covered below, is the single most useful tool a small business can have.
Mistakes in how you get paid
3. Invoicing late
If you invoice at the end of the month for work finished on the 3rd, you've given every client an extra four weeks of credit before the payment clock even starts. Invoice the day work is delivered, or bill milestones as they're completed.
4. Offering generous terms by default
Net-60 or net-90 terms are often granted because a big client asked, not because you could afford them. Negotiate: request an upfront deposit of 30–50% on projects, offer a small discount for early payment, and reserve long terms for clients whose size genuinely justifies them.
5. Depending on one or two clients
When a single client is 40% of revenue, their payment delay becomes your crisis. Concentration also weakens your bargaining position on price and terms. As a rule of thumb, start actively diversifying once any one client passes about a quarter of revenue.
Revenue is vanity, profit is sanity, but cash is reality.
Mistakes in how you spend
6. Adding fixed costs ahead of revenue
A bigger office, a new full-time hire or a long equipment lease all feel like investments in growth. They're also commitments you must pay every month whether or not the expected revenue turns up. Wherever possible, scale with variable costs first — freelancers, short leases, pay-as-you-go tools — and convert to fixed costs once demand is proven.
7. Spending money that belongs to the taxman
Sales tax collected from customers — GST in India, VAT in the UK and Europe — isn't your money. Neither is the income tax you'll owe on this year's profits. Move a fixed percentage of every receipt into a separate account the day it arrives, so tax deadlines become a transfer rather than a scramble.
The 13-week cash forecast
A 13-week forecast covers one quarter, week by week. List expected cash coming in (from actual invoices and their realistic payment dates, not hopes) and cash going out (payroll, rent, suppliers, tax, loan payments). Here's the first four weeks of an illustrative example for a small agency:
| Week | Opening balance | Cash in | Cash out | Closing balance |
|---|---|---|---|---|
| 1 | ₹6,00,000 | ₹1,50,000 | ₹80,000 | ₹6,70,000 |
| 2 | ₹6,70,000 | ₹40,000 | ₹4,20,000 (payroll) | ₹2,90,000 |
| 3 | ₹2,90,000 | ₹0 | ₹2,10,000 (GST + rent) | ₹80,000 |
| 4 | ₹80,000 | ₹3,00,000 | ₹60,000 | ₹3,20,000 |
Week three is the danger zone: a single delayed payment and the business can't meet its obligations. Seen three weeks in advance, that's easy to fix — chase the invoice, move a supplier payment, or draw on a credit line. Discovered on the day, it's a crisis.
Update the forecast every Monday. It takes twenty minutes once it's set up, and it turns cash flow from something that happens to you into something you manage.
