Retention money keeps a builder's cash in the walls.

A civil contractor in a metro region. ~₹55 crore turnover. A promoter who was a civil engineer by training with a genuine delivery record - commercial and institutional projects for private developers and a handful of institutions.

The work was good. The pipeline was there. The balance sheet had held up.

But the business couldn't access the next tier of projects. And cash was getting tighter.

Running-account bills were certified slowly. Retention money - 5–10% of every contract - sat locked until defect-liability periods ended. Mobilisation costs arrived before any collection.

Debtor-plus-retention days stretched past 100.

The firm needed both: funded working capital to execute and performance bank guarantees to bid. What it had was a small CC - and the practice of blocking fixed deposits for every guarantee, quietly draining liquidity.

Construction receivables are certification-dependent and lumpy. Lenders discount them heavily because they can't easily verify what's certified versus what's disputed.

The realistic security here was the promoter's property - not project receivables. That pointed to a collateral-backed WC line, not a large clean CC, supplemented by a non-fund BG limit for tendering.

These are two separate instruments with different purposes. Treating them as one was the root of the constraint.

₹8 crore working capital - a CC plus a WCDL component for mobilisation - secured against a mix of book debts and property collateral (LTV ~60–65%).

₹5 crore performance/financial BG limit for tendering. Not FDs blocked per guarantee - a properly sanctioned, revolving BG line.

Pricing at ~repo + 3.25%. Drawdown tied to active, certified work - not self-certified project progress.

We prepared project-wise cash budgets, certified-vs-uncertified bill schedules, and commissioned the collateral valuation.

The credit committee was cautious about a stalled project in the book. We ring-fenced it, excluded it from the drawing-power calculation, and based DP on the active, certified pipeline only.

Sanction: ~9 weeks, most of it consumed by legal coordination and valuation - not credit concerns.

With mobilisation funded and a real BG line in place, the firm bid for - and won - larger projects.

Turnover grew to ~₹72 crore. The FD-blocking practice ended. Cash that had been frozen came back into circulation. Certification-linked WCDL smoothed the lumpy receivable cycle.
