Working capital for contractors: cash credit, bank guarantees, bill discounting and more

Contracting is a cash-hungry business. You pay for labour, materials and machinery up front, but you get paid only when running bills are certified and released — and part of each bill is often held back as retention. On top of that, almost every tender asks for security in the form of an earnest money deposit, a performance guarantee or a mobilisation advance guarantee.

That is why contractors usually need two kinds of bank limits at the same time: fund-based limits that put cash in your account, and non-fund-based limits — mainly bank guarantees — that let you bid for and execute contracts.

Why contractors face a cash-flow gap

• Bill certification and payment delays. Work is done weeks or months before a running bill is certified and paid.
• Retention money. A portion of each bill is often withheld until completion or the defect-liability period ends.
• Security for every contract. Bid security, performance security and advance guarantees each need a bank limit — and often a cash margin.
• Upfront mobilisation. Equipment, site set-up and early material purchases come before the first bill.

Fund-based facilities: cash credit and overdraft

Cash credit (CC) and overdraft (OD) are revolving limits: you draw what you need, repay as bills come in, and pay interest only on the amount used. Cash credit is typically linked to your current assets — stock and receivables — while an overdraft is often secured by property, fixed deposits or other collateral. Exact product definitions vary by bank.

Drawing power, explained

Within a cash credit limit, the amount you can actually draw at any time is your drawing power (DP). Banks generally calculate it from your monthly stock and receivables statements: paid-for stock plus eligible receivables, minus the margins set in your sanction letter. Older receivables are commonly excluded.

Two practical rules matter:

• Keep stock statements current. Banks expect drawing power to be based on recent statements; drawings against stale statements (typically older than three months) can be treated as irregular.
• Avoid continuous over-drawing. Under RBI's asset-classification norms, a cash credit or overdraft account that stays above its limit or drawing power — or has no credits — for 90 continuous days can be classified as a non-performing asset.

Bank guarantees contractors need

A bank guarantee (BG) is the bank's promise to pay the project owner if you fail to meet your obligations. Contractors commonly need:

• Bid bond / EMD guarantee — at the tender stage, assuring that you will sign the contract if awarded.
• Performance guarantee — assuring that the work will be completed as per the contract.
• Mobilisation (advance payment) guarantee — lets you receive an advance from the project owner before work starts.
• Retention money guarantee — lets you get retention released from running bills against a guarantee instead.

Do bank guarantees block your working capital?

A BG is a non-fund-based facility: no money leaves the bank unless the guarantee is invoked. But it is not free. Banks usually ask for a cash margin (often as a fixed deposit) and/or collateral, and each guarantee uses up part of your sanctioned non-fund-based limit. Margins are set by each bank's policy — for example, Indian Bank's contractor scheme lists a 10% margin on BGs and LCs.

RBI's Non-Fund Based Credit Facilities Directions, 2025 — applicable to guarantees issued or renewed from 1 April 2026 — require guarantees to be irrevocable and unconditional and set out how banks issue and honour them, including electronic BGs.

Surety bonds as an alternative

Since April 2022, insurers in India can issue surety bonds, and central government procurement rules accept insurance surety bonds as bid and performance security alongside bank guarantees. Surety bonds typically don't need the fixed-deposit margins that BGs often do — but not every project owner accepts them, so check the tender terms.

Bill discounting and TReDS

Bill or invoice discounting turns an accepted bill into cash before its due date. For MSMEs, the most important channel is TReDS (Trade Receivables Discounting System) — RBI-authorised electronic platforms where invoices accepted by the buyer are discounted by banks and NBFCs that bid for them. Financing on TReDS is without recourse to the MSME seller.

Large companies and central public sector enterprises must be registered on TReDS, and in June 2026 the MSME Ministry required all central PSEs to settle MSME invoices through TReDS. State government departments and municipal bodies are not covered by that mandate, so whether you can discount bills on a particular contract depends on whether your buyer is on a TReDS platform.

Working capital term loans and equipment finance

Construction equipment is usually funded separately through equipment finance — a term loan with the machine hypothecated to the lender. Several banks also bundle equipment term loans with cash credit and guarantee limits in dedicated contractor schemes.

How banks assess your working capital limit

• Turnover method for smaller borrowers. For micro and small enterprises with fund-based limits up to ₹5 crore, RBI expects working capital to be assessed at a minimum of 20% of projected annual turnover. In practice the total requirement is often taken as 25% of turnover, with the borrower contributing a margin.
• Business-cycle methods for larger borrowers. Above that, banks use their own Board-approved methods based on your operating cycle.
• Contract-based schemes. Contractor schemes typically look at your order book, contract values, turnover and GST returns. Public sector examples include Bank of Maharashtra's Mahabank Scheme for Contractors and Indian Bank's IB Contractors, each covering cash credit, guarantees and equipment loans within defined limits and eligibility conditions.

MSME advantages worth knowing

If your business is a micro or small enterprise registered on Udyam:

• Priority-sector status — bank loans to registered MSMEs count as priority-sector lending.
• No collateral up to ₹20 lakh — under RBI's February 2026 amendment, banks should not take collateral for MSE loans up to ₹20 lakh sanctioned or renewed from 1 April 2026 (raised from ₹10 lakh).
• CGTMSE cover up to ₹10 crore — the Credit Guarantee Fund Trust can guarantee collateral-free credit to MSEs up to ₹10 crore per borrower (from 1 April 2025), covering 75–90% of the amount in default. It is at the lender's option and carries an annual fee.
• Timely-payment protection — under the MSMED Act, buyers must pay micro and small suppliers within the agreed period, capped at 45 days. Whether this covers a specific works contract depends on the contract and your registration, so take legal advice before relying on it.

Common problems — and how to avoid them

• Guarantees eating into limits. Plan your non-fund-based limit around your bidding pipeline, and ask about surety bonds where accepted.
• Stale stock statements. Submit them on time so drawing power reflects your real position.
• Mismatched limits. A limit sized on last year's turnover may not match this year's order book — review limits when you win large contracts.
• Delayed government payments. Use TReDS where your buyer participates, and track MSMED Act timelines.
