Working Capital Finance: CC vs OD vs Bill Discounting, DSCR Calculation & What Banks Check in Audited Financials

The Three Working Capital Weapons: CC, OD, and Bill Discounting

Every business needs oxygen between the invoice and the cheque clearing. Banks offer three routes to that oxygen, and confusing them costs thousands in unnecessary interest and collateral.

Cash Credit (CC)

Cash Credit is the workhorse of Indian working capital. You draw up to a sanctioned limit, pay interest only on what you use, and repay as cash flows in. The bank holds a first charge on your inventory and receivables.

Why CC: Flexibility. Draw Rs. 5 lakh today, Rs. 2 lakh tomorrow. Interest accrues only on outstanding balance.

Cost: Prime lending rate (PLR) + 2-3% spread. Typical: 10-12% per annum.

Compliance burden: High. Banks conduct quarterly stock verification and receivables audits. You must file quarterly CRZ (Current Resources and Liabilities) statements, half-yearly financial statements, and maintain prescribed debt-equity ratios (typically 2:1 maximum).

Renewal: Annually. The bank reviews your audited financials, GST returns, and bank statements.

Overdraft (OD)

OD is simpler but more punitive. Your bank account goes negative up to a sanctioned limit. Interest is levied on the daily overdrawn balance.

Why OD: Speed. Sanctioning can happen in 48 hours for existing current account holders.

Cost: PLR + 1.5-2.5% (cheaper than CC). But banks impose penal interest at 2% above the normal rate if you breach the limit.

Compliance burden: Low. No stock verification or receivables audit.

Best for: High-turnover businesses with predictable weekly cash surpluses (retail, e-commerce aggregators, wholesalers).

Bill Discounting (BD)

You sell receivables (customer invoices) to the bank at a discount. Cash comes immediately; the bank recovers when your customer pays.

Why BD: Speed and no collateral lock-up. Inventory and receivables remain free for other lending.

Cost: Discount rate 6-9% per annum (lowest of the three), but charged only for the tenure until bill maturity.

Compliance burden: Medium. The bank verifies invoice authenticity, checks your customer's creditworthiness, and may ask for invoice confirmation from the buyer.

Best for: Businesses with creditworthy, identifiable buyers and invoices with 30-90 day tenors (pharma distributors, IT services, FMCG wholesalers).

DSCR: The Ratio That Unlocks Your Limit

Debt Service Coverage Ratio (DSCR) measures whether your operating cash flows can service debt. Every bank calculates it before approving or renewing CC/OD.

Formula:

DSCR = Net Operating Cash Flow / Total Debt Service

Where:

• Net Operating Cash Flow = EBITDA (Earnings Before Interest, Tax, Depreciation, Amortisation) or, more conservatively, cash flow from operations per audited financials.


• Total Debt Service = Principal repayment + Interest on all loans (banks, NBFCs, term loans) over the next 12 months.

Example:
Your FY 2024 EBITDA is Rs. 50 lakh. Total debt service (interest + principal) is Rs. 25 lakh.

DSCR = 50 / 25 = 2.0

Banker's expectation: Minimum DSCR of 1.25 for unsecured CC, 1.5-1.75 for larger facilities. A DSCR below 1.0 means you cannot service debt from earnings -- an automatic rejection.

Why this matters: If your DSCR slips from 2.0 to 1.2, the bank will either reduce your CC limit or demand additional personal guarantees.

What Auditors Must Certify -- And What Banks Actually Read

Your Chartered Accountant's audited financials (Balance Sheet, P&L, Cash Flow) are the cornerstone of every credit decision. Here's what the bank's credit team scrutinizes:

1. Revenue Quality and Growth

Banks cross-check audited sales against GST returns (GSTR-1 filed) and bank deposits. A mismatch flags evasion. Flat or declining revenue over two years signals loan rejection or limit reduction.

2. Gross Profit Margin and Operating Leverage

Low or eroding gross margins (< 10% for trading, < 30% for services) suggest thin pricing power. Combined with high overheads, this depresses EBITDA and DSCR.

3. Cash Conversion Cycle

Banks calculate: Days Inventory Outstanding (DIO) + Days Sales Outstanding (DSO) - Days Payable Outstanding (DPO).

A long cycle (e.g., 120 days for a distributor) strains working capital needs and increases CC limits. A negative cycle (you pay suppliers after you sell) is gold -- it reduces working capital lending.

4. Debt Defaults and Red Flags

Auditors note contingent liabilities, pending litigations, and income tax disputes. A major tax demand or litigation can kill credit approval despite strong DSCR.

5. Related-Party Transactions

Large unsecured advances to promoters, family members, or related firms raise concerns. Auditors must disclose these in the notes. Banks often ask for repayment or personal guarantees to cover the risk.

6. GST Compliance

Missed GST filings, high input tax credit claims, or inverted duty structures invite scrutiny. Auditors cross-verify GSTR-3B monthly data.

7. Depreciation and Asset Quality

Abnormally low depreciation or assets written down recently (spinoffs, restructuring) suggest asset quality issues. Banks may haircut the balance sheet value.

Choosing Your Route

Don't pick the cheapest. Pick the right tool:

• CC: You have volatile, lumpy cash needs, strong inventory and receivables, and can tolerate compliance audits.
• OD: You have steady, predictable negative cash periods (1-2 weeks monthly), good credit history, and hate compliance.
• BD: You have stable, creditworthy customers, and invoices with fixed maturity dates.

Most midsize businesses use a combo: CC for inventory float, OD for surprise shortfalls, BD to accelerate customer receivables.

Your DSCR and audited financials are your credit resume. A strong Balance Sheet, clean tax compliance, and DSCR above 1.75 gets you lower rates, higher limits, and faster renewals.
