Working Capital Warnings: Debtor & Inventory Days

A company can report growing profit, defend a healthy gross margin and still trap a year's worth of cash. The warning usually sits below the headline results: customers take longer to pay, stock waits longer to sell, or suppliers demand their money sooner.

The useful signal is not a single working-capital number. It is working capital growing faster than revenue, quarter after quarter. That is when accounting profit stops arriving in the bank.

Vedant Fashions, the company behind Manyavar, offers a clean Indian case. In October 2024, management said working capital ran at “about 110 days.” By the next two calls, that number had disappeared from the discussion. Inve's Promise Tracker marked the commitment as ghosted in its parsed call history (Inve data, as of 2026-06-12).

Vedant Fashions is used here to teach the method, not to express a view on the stock.

What working capital analysis measures

Working capital is the cash tied up in daily operations:

Receivables are sales the customer has not paid for. Inventory is cash sitting on a shelf or factory floor. Payables are supplier credit — goods the company has received but has not paid for yet.

The absolute amount tells you little without context. A large distributor should carry more working capital than a small software company, and the asset-turnover ratio helps show whether that investment produces enough sales. The revealing questions are:

1. Is working capital rising faster than revenue?
2. Which component caused the change?
3. Is the change temporary, or has it persisted for several quarters?
4. Did management quantify when the cash should return?

When receivables and inventory swell, cash from operations can fall while reported profit stays steady. Roughly:

This is why the cash-flow statement and balance sheet must be read beside the income statement. The gap between profit and cash is often the first place an optimistic sales story meets reality.

Vedant Fashions' FY25 revenue from operations rose only 1.4%, from about ₹1,368 crore to ₹1,386 crore. Net cash from operations fell from roughly ₹483 crore to ₹389 crore, while profit after tax was ₹389 crore. The prior year produced ₹1.17 of operating cash for each ₹1 of profit; FY25 produced about ₹1.00. Inventory and receivables absorbed the difference (Vedant Fashions FY25 annual report).

Sign 1 — Debtor days keep rising

Debtor days estimate how long customers take to pay. A sustained rise can mean the company is offering looser credit to protect sales, customers are under stress, or revenue was booked before cash collection became likely.

Use average receivables when possible: opening plus closing receivables, divided by two. A year-end balance can be distorted by seasonality or a large invoice raised just before the reporting date.

The number is sector-dependent. A cash retailer and an engineering contractor should not have the same debtor days. Compare a company with its own history and close peers, then read the notes for overdue balances, expected-credit-loss provisions and related-party receivables.

Vedant's average trade-receivable days rose from about 139 in FY24 to 156 in FY25, while revenue barely moved. On the May 2025 call, the CFO said receivables had increased by around ₹50 crore, mainly because of store additions. Asked whether further expansion would lift receivables again, he answered yes. That does not prove weak collection; it reveals that growth in this franchise model structurally consumes cash and must earn enough to justify it.

Sign 2 — Inventory grows faster than sales

Inventory days estimate how long goods sit before sale. A temporary build can be sensible ahead of a festival, product launch or supply disruption. The warning is stock rising faster than sales without a time-bound reason, or failing to reverse after management's stated event passes.

Check which denominator your data source uses. Cost of goods sold is the usual convention, but some screeners divide inventory into revenue. Either method can show a trend; mixing the two produces a false comparison.

Vedant's closing inventory rose 46% in FY25, from about ₹139 crore to ₹202 crore, although average inventory days moved only from 42 to 45. Management said it had pre-planned production around Eid and store expansion. That is plausible. The test is whether the extra stock sells through and the cash returns in later quarters, not whether the explanation sounds reasonable on the first call.

Sign 3 — Payable days fall

Payables are financing supplied by vendors. Falling payable days mean cash leaves sooner. Sometimes the company chooses to pay early for a discount; sometimes suppliers have shortened terms because trust or negotiating power weakened.

Pair this sign with the other two. Collecting more slowly while paying suppliers faster closes the cash vice from both sides. The working-capital cycle then explains why profit can look healthy while free cash flow deteriorates.

Sign 4 — Working capital consumes more of each sale

Divide operating working capital by revenue and follow the percentage across several years. If a company once needed 15 units of working capital for every 100 of sales and now needs 25, each new sale consumes more cash than the last.

A flat or falling ratio as revenue grows means the business is funding expansion more efficiently. A sustained rise means growth needs an increasing cash subsidy. The next question is whether that investment produces better growth or margins later.

For Vedant Fashions, current assets minus current liabilities rose from about ₹1,019 crore in FY24 to ₹1,206 crore in FY25. Against revenue, that was roughly 75% and 87%. Revenue grew 1.4%, while the cash tied up in the operating balance sheet rose far faster.

Where this reading can mislead you

Working capital is seasonal. A retailer may build stock before a holiday, a manufacturer may buy materials ahead of a shutdown, and a distributor may carry receivables after a large quarter-end shipment. One period rarely proves a trend.

Inflation can also lift inventory value even when units are flat. Acquisitions can add balances without comparable prior-period revenue. Fast growth often requires more receivables and stock before the resulting sales appear. These are reasons to normalise the data, not reasons to ignore it.

The strongest counter-case has three parts: management explains the build precisely, gives a date or operating milestone for reversal, and later filings show the cash returning. A vague claim that inventory is “strategic” is weaker than a quantified plan.

Vedant had credible reasons: Eid timing, store expansion and high gross margins that can make carrying wedding-season stock rational. The concern is narrower. Management supplied a working-capital frame, later acknowledged the build, and then stopped reporting the comparable number in the parsed calls. Inve's guidance ledger for Vedant Fashions keeps that sequence visible so the next filing can resolve it.

A five-minute review

For each annual or quarterly filing:

1. Put revenue, receivables, inventory and payables in one small table.
2. Calculate debtor days, inventory days and payable days with one consistent method.
3. Compare each trend with revenue growth and operating cash flow.
4. Read the notes for aging, impairments, inventory provisions and changes in payment terms.
5. Write down management's explanation and expected reversal date.
6. Check the next two filings against that statement.

The calculation finds the smoke. The notes and later results tell you whether it came from a planned investment or a fire.
