A Bigger Limit Will Not Fix It: Matching Working Capital Finance to Your Cash Cycle

A business can be profitable, growing and still run out of cash by the 25th of every month. When that happens, the reflex is to ask the bank for a larger limit. That is usually the wrong first question. The limit is rarely the problem. The problem is that the money borrowed does not match the shape of the cash the business actually consumes, and no additional limit fixes a mismatch between a 120-day operating cycle and an instrument built for a 30-day one. Working capital finance is not one product. It is a set of instruments with different tenors, security, pricing logic and behaviour under stress, and choosing between them is an engineering decision, not a procurement decision. Get it wrong and you fund a permanent asset with a demand facility, which is the most common structural weakness on SME balance sheets.

Start with the cycle, not the limit

Before you approach any lender, calculate your cash conversion cycle and know what it costs. Inventory days plus receivable days minus payable days. That number, multiplied by your daily cost of sales, is the cash permanently locked inside your operations.

Take a business with turnover of Rs 120 crore and cost of sales at 80 percent, so roughly Rs 26 lakh of cost consumed every day. Inventory sits for 75 days, customers pay in 90, suppliers are paid in 45. Gross working capital is about Rs 49 crore, creditors fund roughly Rs 9 crore, and the net gap is Rs 40 crore. That gap does not disappear in a good month. It is a permanent claim on capital that grows with revenue. Now apply the discipline lenders apply. Under the traditional second method of lending, the bank expects you to fund 25 percent of that gap from long-term sources. Maximum permissible bank finance is Rs 30 crore, and Rs 10 crore has to come from net worth or a term source. Founders who have not run this arithmetic discover it at sanction stage, when the bank asks where the margin is coming from and the answer is nowhere.

Then run the growth case. Grow revenue 30 percent on the same cycle and the gap moves to about Rs 52 crore. You need Rs 12 crore more, of which Rs 3 crore is your own money. At a 5 percent net margin the business generates Rs 6 crore and can just about fund that, provided none of it is distributed. Growth consumes cash. Model it before you commit to it.

Match the instrument to the shape of the gap

Once you know the gap, split it into three layers: the permanent core that never unwinds, the seasonal swing, and the transaction-specific need tied to an identifiable receivable or purchase order. The permanent core should not sit entirely on cash credit. Cash credit is a demand facility. It is repayable on demand, reviewed annually, priced on a repo-linked external benchmark that resets quarterly, and drawn against a monthly stock statement with margins that typically strip out debtors over 90 days. It is flexible, and you pay for that flexibility in both price and fragility. If your utilisation never drops below 70 percent of limit, that portion is not revolving working capital. Carve it into a working capital demand loan with a fixed tenor. The lender gets deployment certainty and usually prices it below the cash credit rate.

The seasonal swing is what cash credit is genuinely for. Size it to your peak month, not your average, and accept that you will pay for the months you do not draw. That is cheaper than running dry in your busiest quarter.

The transaction layer is where most Indian mid-market businesses leave money on the table. If your receivables sit against large corporate or PSU buyers, discount them rather than borrow against them. On TReDS, the invoice is financed against the buyer's credit rating, not yours, which is why a supplier rated BBB can access money at a rate anchored to a far stronger buyer. The RBI issued revised TReDS Directions in June 2026 that removed the mandatory due diligence requirement for MSME sellers and gave platform operators greater operational flexibility, both of which shorten onboarding. If you supply to corporates on 60 to 90 day terms and are not on a TReDS platform, you are financing your buyer's balance sheet with your own borrowed money.

Use non-fund limits before fund-based ones

The cheapest working capital is often the working capital you do not borrow. A letter of credit converts a cash purchase into a 90 or 180 day usance obligation. You pay LC commission plus, if the supplier discounts it, a discounting charge priced against your bank's credit rather than yours. For an importer or a business buying raw material in bulk, this is materially cheaper than drawing on cash credit for the same 90 days, and it does not consume drawing power against stock.

The same logic runs through the export cycle. Pre-shipment credit funds the manufacture of a confirmed order and is liquidated by the export proceeds. Post-shipment discounting funds the gap between shipment and realisation. Both are self-liquidating and both price tighter than a general purpose limit, because the lender can see exactly what repays them.

Bank guarantees deserve the same treatment. Performance and advance-payment guarantees replace cash security deposits with a contingent liability costing a fraction of the deposit's opportunity cost. Businesses in infrastructure, engineering and government supply routinely leave crores blocked in earnest money that a guarantee line would release.

Price is the last question, not the first

The repo rate has been at 5.25 percent since June 2026 and the Monetary Policy Committee held it there in August with a neutral stance. That matters less than founders assume. A repo-linked facility repriced quarterly and an MCLR-linked facility repriced annually behave very differently through a rate cycle, and the difference in headline rate between two lenders is often smaller than the difference in fees, stock audit costs, insurance requirements and an inflexible drawing power formula that leaves a fifth of your sanctioned limit unusable.

Compare on all-in cost of drawn funds and on structural terms: how drawing power is computed, what margins apply on stock and book debts, how ageing is treated, whether limits are interchangeable, and what triggers a review. A limit you cannot draw is not a limit. Ask for the drawing power calculation in writing before you sign.

If a facility is permanently drawn, never swings, and grows every year, it is not working capital. It is quasi-permanent capital sitting on a demand instrument that a lender can reprice or withdraw at renewal, usually at the exact moment your business can least absorb it. That is a capital structure problem, and it is solved with equity, promoter infusion or a term loan, not with a bigger cash credit limit. Before you finance the cycle, shorten it. In the example above, taking 15 days out of the cycle releases about Rs 4 crore permanently. No lender will ever give you money that cheap.
