Working Capital Management & Cash Flow Forecasting

A garment factory can report a profit every month for a year and still fail to pay its workers. This is not a paradox, and it is not rare. It happens whenever cash is locked in the wrong places: fabric sitting in the warehouse, finished garments waiting for shipment, and invoices waiting for buyers to pay, while suppliers demand payment, wages fall due every week, and the bank charges interest on every overdraft day. Profit is an accounting result measured over a period. Cash is the money actually in the bank on a given day. A factory lives or dies on the second, not the first.

Working capital management is the discipline that keeps the two connected. Working capital is current assets minus current liabilities: the stock, receivables, and cash the factory holds, minus the supplier bills, short-term loans, and accrued expenses it owes. It measures the short-term resources available to fund day-to-day operations. Cash-flow forecasting is the forward-looking half of the same discipline: it projects, week by week or month by month, how much cash will arrive and how much must leave, so that a gap is visible while there is still time to close it. Together they answer the only liquidity question that matters: will the factory have cash when the bills fall due.

Start from the balance sheet at a single date, never mixing dates, because working capital is a snapshot. The illustrative woven shirt factory used in this lesson holds current assets of BDT 45,000,000: inventory of BDT 22,000,000 in fabric, trims, and finished goods, trade receivables of BDT 18,000,000 in unpaid buyer invoices, and cash of BDT 5,000,000. Its current liabilities are BDT 28,000,000: trade payables of BDT 20,000,000 in unpaid supplier bills, and a short-term loan of BDT 8,000,000.

Working capital is 45,000,000 minus 28,000,000, which is BDT 17,000,000. The current ratio is 45,000,000 divided by 28,000,000, which is 1.6071, reported as 1.61. A ratio above 1 means current assets exceed current liabilities, which is the minimum condition for short-term solvency. A ratio near 2 is often cited as comfortable, but the right level depends on how quickly the assets convert to cash. BDT 22,000,000 of fabric stock is not the same as BDT 22,000,000 of cash, and a factory with slow-moving or obsolete stock can show a healthy current ratio while being unable to pay wages. Always read working capital alongside the quality of its components: how old is the stock, how overdue are the receivables, and how much of the cash is already committed.

Working capital also has a cost. Every taka held in stock or receivables is a taka that must be financed, either from the owner funds, from supplier credit, or from bank borrowing. A factory that holds two months of fabric stock when one month would do is financing an extra month of fabric for no benefit. Working capital management is therefore not just about having enough, it is about having no more than necessary, because excess working capital is profit spent on financing nothing.

The cash conversion cycle compresses the whole working capital story into a single number of days. It equals inventory days plus receivable days minus payable days. Inventory days measure how long stock sits before it is sold. Receivable days measure how long buyers take to pay after invoicing. Payable days measure how long the factory takes to pay its suppliers. Add the first two, subtract the third, and the result is the number of days cash is trapped between paying for inputs and collecting from customers.

For the illustrative factory, inventory days are 45, receivable days are 60, and payable days are 30. The cash conversion cycle is 45 plus 60 minus 30, which is 75 days. Every production cycle traps cash for 75 days. If the factory spends BDT 20,000,000 a month on inputs, it permanently carries about 75 days of that spending, roughly BDT 50,000,000, in the cycle, financed from its own funds or from borrowing. Shorten the cycle by ten days and roughly BDT 6,700,000 of cash is released, because 10 days out of 30 days in a month, applied to BDT 20,000,000 of monthly spending, is 6,666,667, reported as approximately BDT 6,700,000.

Each component has its own lever. Inventory days fall when the factory orders fabric closer to cutting dates, negotiates supplier stockholding, or clears slow-moving styles. Receivable days fall when the factory enforces payment terms, offers an early-payment discount, or uses export bill discounting. Payable days rise when the factory negotiates longer supplier terms, but only to the point where supplier trust is preserved, because a supplier who is paid late stops delivering, and a stopped delivery costs more than the financing saved. The cycle is a system, and pulling one lever without watching the others creates a new problem while solving the old one.

A cash gap has a price, and it should be calculated before any decision that lengthens it. Consider a fabric order of BDT 4,000,000. The supplier requires payment 30 days before shipment. The buyer pays 60 days after shipment. The gap between paying for the fabric and collecting from the buyer is 90 days. Financing BDT 4,000,000 for 90 days at an illustrative annual interest rate of 12 percent costs 4,000,000 times 0.12 times 90 divided by 365. The annual interest is 480,000. Multiplied by 90 and divided by 365, the cost is BDT 118,356.16, reported as BDT 118,356.

Divide that cost by the gap to find the daily price of delay: 118,356 divided by 90 is BDT 1,315.07 per day, reported as about BDT 1,315. Every day shaved off the gap saves about BDT 1,315 on this single order, and every day added costs the same. This daily figure is the right way to evaluate term negotiations. A supplier offering 10 extra days of credit on this order is offering about BDT 13,150 of value. A buyer demanding 10 extra days to pay is imposing about BDT 13,150 of cost. A price discount of BDT 10,000 in exchange for 10 extra days of payment is a bad deal, and the daily figure proves it in one line.

The same logic scales to the whole factory. A 75-day cash conversion cycle on monthly input spending of BDT 20,000,000 traps about BDT 50,000,000, and financing that balance at 12 percent costs about BDT 6,000,000 a year. Cutting the cycle by 10 days saves about BDT 800,000 a year in interest alone, before counting the avoided overdraft penalties and the bargaining power of a factory that pays its suppliers on time. Working capital improvement is often the cheapest profit improvement available, because it requires no new orders and no new machines, only better timing.

A cash-flow forecast has a rigid structure, and the rigidity is what makes it trustworthy. Start with opening cash. Add expected receipts, which are collections from buyers, not sales. Subtract expected payments: supplier bills, wages, overhead, loan repayments, and tax. The result is closing cash, which becomes next month opening cash. Every month must reconcile exactly, and the whole forecast must reconcile from the first opening balance to the final closing balance.

Work the illustrative three-month forecast. Opening cash in month 1 is BDT 5,000,000. Month 1 receipts are BDT 20,000,000 and payments are BDT 18,500,000, giving net cash flow of positive BDT 1,500,000 and closing cash of BDT 6,500,000. Month 2 opens at BDT 6,500,000, receives BDT 22,000,000, pays BDT 21,000,000, nets positive BDT 1,000,000, and closes at BDT 7,500,000. Month 3 opens at BDT 7,500,000, receives BDT 19,000,000, pays BDT 23,000,000, nets negative BDT 4,000,000, and closes at BDT 3,500,000. The three-month totals reconcile: receipts of 20,000,000 plus 22,000,000 plus 19,000,000 equal BDT 61,000,000, payments of 18,500,000 plus 21,000,000 plus 23,000,000 equal BDT 62,500,000, net flow is negative BDT 1,500,000, and opening cash of BDT 5,000,000 minus 1,500,000 equals the final closing cash of BDT 3,500,000.

Month 3 deserves attention. The forecast shows a negative net flow of BDT 4,000,000, yet closing cash stays positive at BDT 3,500,000, because months 1 and 2 built a buffer. That is the purpose of forecasting: month 3 problem is visible in month 1, while there is still time to accelerate a collection, delay a non-critical payment, or arrange an overdraft. A forecast that is read only when month 3 arrives is a history lesson, not a management tool. The rule is simple: act on a forecast gap in the month you first see it, not in the month it falls due.

Three levers release trapped cash, and they should be pulled in order of cost. The cheapest is collecting faster. Monthly sales of BDT 20,000,000 on 60-day terms hold about two months of sales in receivables, which is BDT 40,000,000. Cutting terms to 45 days holds about one and a half months, which is BDT 30,000,000. The difference, BDT 10,000,000, is released as cash once the shorter terms take effect. An early-payment discount can achieve the same result without renegotiating terms: a 2 percent discount for payment within 10 days costs BDT 400,000 on BDT 20,000,000 of sales, but if it brings collections forward by 50 days, it saves about 50 days of financing on BDT 20,000,000 at 12 percent, which is 20,000,000 times 0.12 times 50 divided by 365, which is BDT 328,767, plus the avoided overdraft risk. Compare the discount cost against the financing saved, in numbers, before offering it.

The second lever is holding less stock. Fabric stock of BDT 22,000,000 against monthly fabric consumption of BDT 11,000,000 represents two months of cover. Cutting cover to one and a half months releases BDT 5,500,000, because 22,000,000 minus 16,500,000 is 5,500,000. The risk is stock-out: a delayed fabric delivery stops cutting, and a stopped line costs more than the interest saved. Cut stock on standard, readily available fabrics first, and keep buffer stock on critical, long-lead items. Stock reduction is a precision exercise, not a clearance sale.

The third lever is paying suppliers later, and it is the most dangerous of the three. Extending payable days from 30 to 45 on monthly purchases of BDT 15,000,000 releases about BDT 7,500,000, because 15 days of purchases is half a month. But a supplier paid late may refuse the next order, demand cash in advance, or raise prices, and any of those responses costs more than the financing saved. Negotiate longer terms openly, in exchange for larger or more regular orders, and never stretch terms by simply paying late without agreement. Supplier trust is working capital too, and it is the hardest kind to rebuild once spent.

Forecast frequency should match cash pressure. Monthly forecasting is adequate when the closing balance is comfortable and no large payment falls due. Weekly forecasting is necessary when the balance is thin, when a large loan repayment approaches, or when a major buyer payment is uncertain. Daily forecasting is necessary during a crisis: a delayed shipment, a buyer payment failure, or a week when wages and a loan instalment fall due together. A monthly forecast in a crisis hides the exact day the money runs out, and the exact day is the only thing that matters.

Forecast accuracy also needs a feedback loop. Every month, compare forecast receipts against actual collections and forecast payments against actual payments, and record the variance for each major line. If buyer collections consistently arrive two weeks later than forecast, the forecast assumption is wrong, not the buyers, and the assumption must change. A forecast that is never compared against reality drifts into optimism, and an optimistic forecast is worse than no forecast, because it encourages spending against cash that will not arrive on time.

Four warning signs deserve immediate attention. The first is a falling current ratio combined with rising overdraft use, which means short-term borrowing is funding a growing gap rather than a temporary timing difference. The second is receivable days rising above agreed terms, which means buyers are paying late and the factory is financing them for free. The third is inventory days rising while sales are flat, which means stock is accumulating that nobody ordered. The fourth is a forecast that shows negative cash in any week, even if the month-end balance is positive, because wages and supplier bills fall due on specific days, not at month-end.

The survival test is blunt and should be run monthly: if the largest buyer delayed payment by 30 days, and the largest supplier demanded cash on delivery, would the factory still pay wages next week. If the answer is no, the factory is running on timing luck, and the working capital actions in this lesson, faster collections, leaner stock, negotiated terms, and a weekly forecast, are not improvements to consider later. They are the work of this month.

Working capital equals current assets minus current liabilities, and the current ratio equals current assets divided by current liabilities. The cash conversion cycle equals inventory days plus receivable days minus payable days, and it measures how long cash is trapped in each cycle. A cash-flow forecast starts from opening cash, adds collections, subtracts payments, and must reconcile exactly to closing cash, month by month and in total. Release cash by collecting faster, holding less stock, and negotiating supplier terms openly, in that order of risk. Forecast weekly when cash is tight and daily in a crisis, compare every forecast against actuals, and run the survival test monthly. Profit tells you whether the factory earns. Cash flow tells you whether it survives, and survival comes first.
