# The Cash Conversion Cycle: How Long Does Cash Sleep? *One number joins inventory, receivables and suppliers — and explains why you profit on paper while gasping at the bank* > **In short:** What the cash conversion cycle (CCC) is and how to compute it from three figures you already have — with a full worked example and four ways to shorten it. - **URL:** https://www.snad.io/en/blog/dawrat-tahwil-naqdi-cash-conversion-cycle - **Arabic original:** https://www.snad.io/blog/dawrat-tahwil-naqdi-cash-conversion-cycle - **Category:** Guides — Core Accounting - **Tags:** Cash Flow, Financial Management, Inventory, Small Business, Snad - **Published:** 2026-08-24 - **Updated:** 2026-08-24 - **Publisher:** Snad (snad.io) You pay your supplier today, sell the goods a month later, and your customer settles a month after that. For all of that time your cash is out of your account — working for someone else. The **cash conversion cycle** is the number of days between cash leaving to buy goods and cash returning from the customer. One number that summarises three disciplines: inventory, collection and supplier terms. A business that does not know its number manages it by feel — this article turns it into arithmetic on three figures you already have. ## What exactly does the cycle measure? The cycle answers one question: **how many days does the money you put into goods stay out of your account before it comes back?** It has three stages, each with its own indicator: | Stage | Indicator | The question | |---|---|---| | Goods in the warehouse | Days inventory outstanding (DIO) | How long until it sells? | | Invoice with the customer | Days sales outstanding (DSO) | How long until they pay? | | Supplier invoice with you | Days payables outstanding (DPO) | How long before you pay? | The formula: **CCC = DIO + DSO − DPO.** Note the last sign: supplier days are **subtracted** — every day a supplier waits is a day they finance your stock instead of you. That is why the cycle can go negative in rare models: whoever collects from customers before paying suppliers runs the money the other way round. ## The calculation, from three figures you own Each indicator comes from two numbers in your reports: - **DIO** = (average inventory ÷ cost of goods sold) × 365 - **DSO** = (average receivables ÷ credit sales) × 365 - **DPO** = (average payables ÷ credit purchases) × 365 Three notes that prevent a wrong answer: 1. **Averages, not the closing balance**: (opening + closing) ÷ 2 — a single day's balance can be distorted by a season or one deal. 2. **Credit sales only** in DSO: mixing cash sales into the denominator produces a number prettier than the truth. 3. **The same period top and bottom**: a year's balances over a quarter's sales produce precise-looking nonsense. If your system holds inventory, invoices and receivables in one database, the three figures are already in its reports — the whole computation takes minutes, not an accounting session. ## A full worked example A small wholesaler's year: - Average inventory 200,000 and COGS 1,200,000 → DIO = (200,000 ÷ 1,200,000) × 365 ≈ **61 days** - Average receivables 150,000 on credit sales of 1,500,000 → DSO = **37 days** - Average payables 100,000 on credit purchases of 1,100,000 → DPO = **33 days** **CCC = 61 + 37 − 33 = 65 days.** What the number means in practice: every unit of currency that enters stock disappears for 65 days. If the wholesaler wants to lift monthly sales by 100,000 at a cost of 80,000, he must finance roughly **173,000** extra (80,000 × 65 ÷ 30) before the growth ever shows in his balance. Which is the commonest explanation of the "profitable but gasping" paradox: growth on a long cycle consumes cash faster than it yields profit — temporarily, but temporary is what bankrupts. ## Four ways to shorten the cycle Each term of the formula has its own lever: **1. Cut inventory days by buying more precisely, not less.** Watch turnover per item; the slow item freezes cash for nothing. The problem is rarely "too much stock" — it is stock distributed wrongly across items. **2. Cut collection days with instant invoicing and steady reminders.** An invoice issued a week after delivery added a week to the cycle before the customer even began to be late. Send the invoice at the moment of delivery and remind before the due date, not after it. **3. Lengthen payables by negotiation, never by lateness.** The difference is fundamental: longer agreed terms improve your cycle and keep the supplier; unilateral delay improves it for a month and costs you prices and priority afterwards. **4. Join the three in one system.** When the invoice, the stock and the receivable live in one database — as they do in **Snad** — the indicators are computed from live data rather than a month-end spreadsheet, and every purchasing decision or payment term shows its effect on the cycle in the reports as it happens. ## Frequently asked questions ### What is the cash conversion cycle in short? The number of days between paying cash for goods and collecting it back from the customer. It is computed as days of inventory + days of receivables − days of payables. The shorter it is, the less cash sits frozen in operations. ### What is a good CCC number? There is no universal figure — cash retail lives on a very short cycle while credit wholesale naturally runs longer. The two useful measures are your own trend across quarters, and comparison with businesses that share your model rather than a general average. ### Is a negative cycle good or dangerous? Negative means you collect from customers before paying suppliers — an excellent cash model while it stays stable, but it makes your growth financed by supplier credit, so any wobble in sales shows up immediately in your ability to pay. ### How often should I review the cycle? Quarterly is enough for most small businesses; monthly if your stock moves fast or your growth is quick. What matters most is computing it the same way every time so you compare like with like. --- ## About the publisher **Snad (سند)** — a private Saudi software company based in Riyadh, founded 2025.
