Cash flow basics for small business owners: why profit and cash are not the same

Cash flow is the movement of money into and out of your business over time. Profit tells you whether you earned more than you spent over a period; cash flow tells you whether you have money in hand on the day rent, salaries and suppliers must be paid. The two often disagree. A business can be profitable on paper and still be unable to pay its bills next Thursday, which is why owners need to watch both.

Profit and cash are different things

Imagine a hypothetical electrical goods wholesaler in Rangpur. In one busy month it sells a lot of stock to retailers on credit, at a good margin. On paper, that is a profitable month. But the retailers will pay over the coming weeks, and the wholesaler has already paid its own supplier in advance. The profit is real, yet the bank balance is close to empty.

Common reasons profit and cash move apart:

• Credit sales. The sale is recorded now; the cash arrives later.
• Stock. Money spent on stock leaves your account long before the goods sell.
• Advance payments to suppliers or landlords.
• Loan repayments. The repayment reduces cash, but only the interest counts as an expense when profit is calculated.
• Equipment purchases. A large amount of cash leaves at once, while the accounts spread the cost over several years.
• Owner withdrawals for household needs.

Where cash gets stuck

Think of a cash cycle. Money leaves to buy stock or materials, waits as stock, turns into a sale, waits again with a customer or courier, and finally comes back to you. The longer each stage lasts, the more cash the business needs just to keep running.

Common waiting points for businesses in Bangladesh:

• Stock sitting on shelves or in a godown, especially slow-moving items.
• Baki to regular customers, often recorded only in a khata.
• Cash-on-delivery money held by the courier until it is settled to you.
• Payments from corporate or institutional buyers that pass through slow approvals.
• Seasonal stock bought weeks before Eid, Puja or winter.

Shortening any of these waits frees cash without a single extra sale.

A simple weekly cash forecast

A forecast does not need special software. A spreadsheet or a notebook is enough.

1. Count cash in hand today: the cash box, every bank account, and bKash and Nagad balances.
2. List expected cash in for each of the coming weeks: customer payments due, COD settlements, and sales you are fairly sure of.
3. List expected cash out: supplier bills, salaries, rent, utility bills, loan instalments, ad spend, and any tax or VAT payments your accountant has told you about.
4. Calculate the closing balance: opening balance plus cash in minus cash out. Each week's closing balance becomes the next week's opening balance.
5. Mark any week where the closing balance falls below a safety cushion you have chosen.
6. Update every week. Replace the forecast with what actually happened, and add one more week at the end.

The value is not precision. It is seeing a shortage weeks before it arrives, while you still have choices: chase a payment, delay a purchase, or arrange finance calmly instead of in a panic.

Ways to improve cash flow

Bring money in sooner

• Invoice on the day you deliver, with a clear due date.
• Ask for an advance on large or custom orders.
• Make digital payment easy, and confirm COD orders before dispatch so fewer parcels come back.
• Follow up on baki politely and on a fixed schedule.

Let money go out at the right time

• Agree payment terms with suppliers instead of paying early out of habit.
• Buy slow-moving stock in smaller, more frequent batches.
• Time large purchases after your strong sales weeks.

Protect the cushion

• Keep business and personal money in separate accounts.
• Build a reserve for slow months, and decide its size with your accountant.
• Avoid paying for machines or renovation out of day-to-day working cash if a better financing option exists.

Common questions

Is this the same as a cash flow statement? No. A cash flow statement is a formal report your accountant prepares, looking back at a past period. A weekly forecast is a management tool that looks ahead. You need the forecast even if you rarely read the statement.

How far ahead should I forecast? Far enough to see your next large outflow, such as a season's stock or a bonus month. For many small businesses a few months of weekly rows is enough; adjust it to your own cycle.

My bank and wallet records never match my sales. That is common when money arrives through several channels. Matching them is worth automating; see reconciling bKash, Nagad and bank statements.

Should I take a loan to cover a shortfall? It depends on why the shortfall exists. If it is a timing gap, such as a large order paid later, short-term finance can make sense. If the business loses money on each sale, a loan only delays the problem. Check your unit economics first, and talk to your accountant or bank before deciding.

Your next step this week

• Count all cash today, across every account and wallet.
• List who owes you money, how much, and since when.
• Draft four weeks of cash in and cash out.
• Pick one waiting point from the list above and shorten it.

Once the forecast is a habit, it belongs next to your other key numbers on an owner's KPI dashboard. If you want help setting up the forecast and the routines around it, that is part of my business development work.
