Working Capital Management for Small Business: A Weekly System for Cash, Stock and Credit

A growing business can report profit and still struggle to pay salaries, suppliers or taxes.The reason is often working capital. Cash leaves the business before cash from customers comes back.For founders, working capital management is not an accounting exercise. It is the operating system that controls how much money gets trapped in stock, unpaid invoices and day-to-day commitments.What is working capital?The standard balance-sheet formula is:Working capital = Current assets − Current liabilitiesCurrent assets usually include cash, receivables and inventory. Current liabilities include payables and short-term obligations.For operating decisions, founders should also look at how much cash the business must fund while it waits for inventory to sell and customers to pay.The three places where cash gets stuckAreaTypical problemFounder questionInventoryToo much stock or slow-moving stockHow many days of cash are sitting on shelves?ReceivablesCustomers pay lateHow quickly do invoices turn into cash?PayablesSuppliers are paid before customer cash arrivesAre supplier terms aligned with our cash cycle?Indian SME research has found that businesses often manage working capital informally, while cash conversion cycle and net working capital are useful monitoring metrics.The cash conversion cycleThe cash conversion cycle helps you understand how long operating cash stays tied up.CCC = Inventory days + Receivable days − Payable daysSuppose a distributor has:45 inventory days50 receivable days30 payable daysIts cash conversion cycle is:45 + 50 − 30 = 65 daysThat means cash can remain committed to the operating cycle for roughly 65 days.Reducing the cycle does not automatically mean cutting every number. The goal is to remove avoidable cash lock-up without damaging sales or supplier reliability.How much working capital do you actually need?Build a simple monthly operating estimate.Imagine a small manufacturer with:₹30 lakh monthly sales₹18 lakh monthly variable operating cost45 days of receivables30 days of inventory30 days of supplier creditApproximate receivables at 45 days of sales:₹30 lakh × 45 ÷ 30 = ₹45 lakhApproximate inventory at 30 days of variable cost:₹18 lakh × 30 ÷ 30 = ₹18 lakhApproximate payables at 30 days of variable cost:₹18 lakhA simplified operating working-capital requirement is therefore:₹45 lakh + ₹18 lakh − ₹18 lakh = ₹45 lakhThis is not a substitute for a proper finance assessment, but it shows founders why growth can consume cash.Why faster growth can create a cash problemIf sales rise from ₹30 lakh to ₹45 lakh per month while payment terms and inventory days stay unchanged, receivables and inventory also grow.Your P&L may look better while your bank balance becomes tighter.This is common in B2B distribution, manufacturing, agencies with long billing cycles and businesses that must buy stock before selling it.A weekly working capital dashboardYou do not need a complicated finance system. Review these numbers every week:MetricWhat it tells youCash balanceImmediate liquidityReceivables due this weekExpected collectionsReceivables overdueCollection riskInventory valueCash tied in stockSlow-moving inventoryPotential trapped cashPayables due this weekNear-term obligations13-week cash forecastUpcoming funding gapCash conversion cycleOperating cash efficiency1. Improve receivables before borrowing moreFounders often ask for a larger overdraft when the first problem is collections.Start with invoice discipline:Send invoices immediately after the agreed milestone.Confirm the customer's accounts-payable process before the first invoice.Put the due date clearly on every invoice.Ask for purchase orders where relevant.Follow up before, not only after, the due date.Track disputes separately from ordinary delays.If a ₹10 lakh invoice is delayed by 30 extra days, you effectively finance ₹10 lakh of your customer's operations for another month.2. Set customer credit limitsRevenue should not automatically create unlimited credit.Define a limit based on:Customer payment historyOrder frequencyFinancial strengthConcentration riskYour own cash positionA customer who already owes ₹8 lakh may not need another ₹5 lakh shipment just because the sales team can book it.3. Treat inventory as cash with a shelf lifeInventory is not harmless until it becomes obsolete. It consumes cash from the day you buy it.Classify stock into:Fast movingNormal movingSlow movingDead or obsoleteThen ask why slow stock exists. Common reasons include inaccurate forecasts, minimum order quantities, too many SKUs, seasonal buying and products kept alive despite weak demand.4. Calculate inventory days by categoryA single company-wide inventory number can hide problems.Your best-selling category may turn every 20 days while another category sits for 120 days.Review inventory days by SKU family. Decide whether slow items need lower reorder points, bundles, liquidation or discontinuation.5. Use supplier terms intelligentlyPaying suppliers early is not always financially smart. Paying late without agreement is also not a strategy.Negotiate terms that match your operating cycle.If customers pay you in 45 days but you pay suppliers in 15 days, you fund a 30-day timing gap before considering inventory.Ask suppliers about:30, 45 or 60-day termsEarly-payment discountsSmaller order batchesConsignment where practicalScheduled deliveriesCompare the value of an early-payment discount with the cash you give up.6. Separate profitable growth from cash-hungry growthBefore accepting a large new order, model its working-capital requirement.Suppose an order produces ₹3 lakh contribution but requires ₹20 lakh of inventory and receivables to be funded for 75 days.The order can be profitable and still create a liquidity problem.Ask:How much cash goes out first?When will we invoice?When will we collect?Can we get an advance?Can supplier terms fund part of the cycle?What happens if payment is 30 days late?7. Use a 13-week cash forecastA balance sheet shows a point in time. A cash forecast shows when the pressure arrives.For each of the next 13 weeks, estimate:Opening cashCustomer collectionsOther inflowsSupplier paymentsPayrollTax paymentsLoan repaymentsCapital expenditureClosing cashUpdate it every week using actual collections and payments.8. Match financing to the problemBorrowing can be useful when the underlying cycle is healthy.Recurring short-term operating gaps may suit working-capital facilities. Specific receivables may suit invoice financing or discounting. Machinery and long-life assets generally need longer-term funding rather than a facility meant for day-to-day cash.Do not borrow simply to preserve bad inventory or repeatedly finance customers who never pay on time.9. Build a working-capital rule for sales teamsSales incentives based only on invoiced revenue can create poor cash behaviour.Consider tracking:Collections against salesOverdue receivablesDiscounts givenCustomer credit exposureGross or contribution marginThe best sale is not always the largest invoice. It is a sale that produces margin and converts into cash within an acceptable period.A 30-day working-capital improvement planDays 1 to 7: MeasurePrepare receivable ageing.Calculate inventory days.List supplier terms.Calculate cash conversion cycle.Build a 13-week cash forecast.Days 8 to 14: CollectContact every overdue customer.Resolve disputed invoices.Set collection owners.Introduce credit limits.Days 15 to 21: Release stock cashIdentify slow-moving SKUs.Stop unnecessary reorders.Reduce minimum stocking levels where safe.Create a plan for dead inventory.Days 22 to 30: Align termsRenegotiate key supplier terms.Review customer payment terms.Set approval rules for exceptional credit.Choose financing only for the remaining healthy gap.Common mistakesWatching profit but not cash. Profit and liquidity are different.Growing receivables faster than sales. Revenue quality matters.Buying stock because suppliers offer discounts. A discount is expensive if the inventory does not move.Using one inventory number. Review category and SKU behaviour.Borrowing before fixing collections. Debt can hide operating problems.Paying everyone early. Protect supplier trust, but use agreed terms.FAQsWhat is good working capital?There is no single ideal rupee amount or ratio for every business. The right level depends on industry, operating cycle, seasonality, credit terms and growth.Can a profitable business have negative cash flow?Yes. Cash can be tied in receivables, inventory or other uses even when accounting profit is positive.What is the most useful working-capital metric for a founder?Use several together. Cash conversion cycle is useful for operating efficiency, while a 13-week cash forecast shows whether the business can meet upcoming commitments.Should I reduce inventory as much as possible?No. Too little stock can cause lost sales and production delays. The goal is the right inventory for service levels and demand.When should I use working-capital finance?Use finance for a clear, measurable timing gap with healthy underlying economics. Fix chronic collection, pricing or inventory problems first.Your weekly habitEvery week, ask three questions: How much cash is stuck in stock? How much is stuck with customers? Which payments must leave before that cash returns?If you can answer those three questions with numbers, working capital becomes manageable rather than surprising.SourcesSmall Enterprise Research, Working capital management: evidence from Indian SMEsAditya Birla Capital, Working Capital Management
