A garment factory can report a shorter cash conversion cycle and still struggle to fund its next order. Sales may have grown. A large buyer may be late. The ratio may also have changed because someone used total sales where credit sales were needed.
The cash conversion cycle, or CCC, links three parts of factory funding. These are inventory, customer credit and supplier credit. Its value comes from the three parts behind the total. A single number cannot show whether stock is usable or a customer will pay. It cannot confirm that a supplier has agreed to longer terms.
This guide develops an original 90-day factory example in currency units, shown as CU. It then tests denominator choices, seasonal averages, growth, and proposed improvements. All figures are illustrative. They are not a benchmark for the garment industry or a forecast for a particular factory.
Read the three parts before the total
Days inventory outstanding, or DIO, is a value-based stock measure. It compares inventory with the rate at which costs pass through sales. Days sales outstanding, or DSO, relates customer receivables to credit sales. Days payable outstanding, or DPO, relates supplier balances to a stated purchase or cost base.
The usual relationship is:
Cash conversion cycle = DIO + DSO − DPO.
Inventory and receivables represent funds committed to operations. Supplier credit offsets part of that need. The cycle is expressed in days, while inventory plus receivables less payables is expressed in money. Those two measures answer related but different questions.
ACCA's working-capital guide explains the cycle and the importance of liquidity. It also recognises the raw-material, work-in-progress, and finished-goods stages in manufacturing. A factory should keep those stages visible when investigating its total inventory balance.
The ratio is an estimate based on balances and flows. A reported cycle of 54 days is an estimate across the operation. Each garment order may take a different time from supplier payment to buyer receipt. Orders overlap, costs enter at different stages, and different customers have different payment terms.
Define the calculation before collecting figures
For this internal management analysis, use the following formulas:
DIO = average inventory ÷ cost of goods sold × days in the period.
DSO = average trade receivables ÷ credit sales × days in the period.
DPO = average material-supplier payables ÷ credit material purchases × days in the period.
The last definition is deliberate. The example's payable balance contains material suppliers only. Its denominator therefore contains purchases on credit from those suppliers. Wages, loan balances, and amounts owed for new machines are outside that calculation.
ACCA's ratio-analysis article explains payables days using credit purchases. Outside analysts may use cost of sales when credit-purchase data is missing. Both conventions appear in published material. State which one is being used before comparing two results.
All flows must cover the same period. For a 90-day analysis, divide by the period's sales, costs, or purchases and multiply by 90. Do not combine quarterly sales with 365 days. If the business uses a different day-count convention, keep it consistent and disclose it.
Use one entity, currency, and accounting basis. Match the treatment of tax, returns, and credit notes between balances and flows. Check whether a receivable includes tax. Dividing that amount by sales excluding tax may distort the result. The worked example excludes tax and foreign-currency effects.
Build a factory example that reconciles
During the illustrative 90 days, credit sales are CU1,080,000 and cash sales are CU270,000. Total sales are CU1,350,000. Cost of goods sold is CU810,000. Material purchases total CU600,000, of which CU540,000 are on credit and CU60,000 are paid in cash.
The balances below exclude customer advances, supplier advances, losses, and disputed adjustments. For this first calculation, the opening-and-closing average is the chosen estimate. A later section tests that choice against a seasonal pattern.
Balance, CU | Opening | Closing | Simple average |
|---|---|---|---|
Raw materials | 180,000 | 270,000 | 225,000 |
Work in progress | 90,000 | 90,000 | 90,000 |
Finished goods | 90,000 | 90,000 | 90,000 |
Total inventory | 360,000 | 450,000 | 405,000 |
Trade receivables | 396,000 | 468,000 | 432,000 |
Material-supplier payables | 144,000 | 180,000 | 162,000 |
The inventory figures fit the cost flow. Materials used equal opening stock plus purchases less closing stock. Here that is CU180,000 + CU600,000 − CU270,000 = CU510,000. Add CU300,000 of conversion cost, giving CU810,000 of production cost. Work in progress and finished goods have no net change, so cost of goods sold is also CU810,000.
The supplier and customer accounts can be checked as well. With no other movements, customer collections against credit sales are CU396,000 + CU1,080,000 − CU468,000 = CU1,008,000. Payments against credit material purchases are CU144,000 + CU540,000 − CU180,000 = CU504,000. Cash purchases of CU60,000 are separate.
These checks show that the example's balances and flows can coexist. They do not form a complete cash-flow statement. That would also need payroll, overhead payments, taxes, funding and other cash movements.
Calculate the operating days
Divide each flow by 90 to make the daily rates clear. Cost of goods sold is CU9,000 per day. Credit sales are CU12,000 per day. Credit material purchases are CU6,000 per day.
Component | Calculation | Days |
|---|---|---|
DIO | 405,000 ÷ 810,000 × 90 | 45 |
DSO | 432,000 ÷ 1,080,000 × 90 | 36 |
DPO | 162,000 ÷ 540,000 × 90 | 27 |
CCC | 45 + 36 − 27 | 54 |
The inventory and receivables periods add to 81 days. The defined supplier-credit period offsets 27 days, leaving a 54-day cycle. This points to a funding need within operations, but it does not specify the amount or date of a bank borrowing.
Average operating funds in these three balances are CU405,000 + CU432,000 − CU162,000 = CU675,000. This is a selected operating working-capital measure. It excludes cash and short-term debt, among other items. The whole company's current assets less current liabilities would give a different measure.
Keep both figures in the review. The 54 days explain relative timing; CU675,000 shows the average amount in the selected balances. The closing balance is different again. It is CU450,000 + CU468,000 − CU180,000 = CU738,000 at that date.
See how denominator errors can partly cancel
Suppose the analyst divides receivables by total sales of CU1,350,000. The result is 28.8 days, instead of 36. Cash sales have increased the denominator even though they did not create the receivables being measured. The reported collection period is understated by 7.2 days.
Now suppose the analyst uses cost of goods sold for the material-supplier DPO. CU162,000 ÷ CU810,000 × 90 gives 18 days, rather than 27. The denominator now includes conversion costs that did not create those material payables.
With both substitutions, the reported cycle becomes 45 + 28.8 − 18 = 55.8 days. That looks close to the defined 54-day result. Yet two of its components differ by much more. Agreement at the total level cannot validate the calculation.
BDC's cash-cycle guide illustrates a cost-of-goods-sold version of DPO and uses average balances. Such a convention can support a consistent external comparison. Here the factory knows its credit material purchases. That flow is a closer match to the selected supplier account.
Even total material purchases are not interchangeable with credit purchases. Using CU600,000 gives 24.3 payable days. The CU60,000 cash-purchase portion did not create supplier credit. Label any proxy and retain the underlying amounts so the reader can reproduce the result.
Choose an average that reflects the season
The simple average is easy to calculate: add opening and closing balances, then divide by two. It works as an estimate, but those two dates may miss a large buildup between them. Garment factories often buy fabric before a selling season or hold finished goods ahead of an agreed shipment window.
Using closing balances alone changes the main example too. Closing inventory of CU450,000 gives 50 days. Closing receivables of CU468,000 give 39 days, while closing payables of CU180,000 give 30. The total becomes 59 days rather than 54. That is a closing-balance version of the measure, not evidence that five days were suddenly lost in the operation.
Keep the comparison basis stable. Suppose last quarter used opening-and-closing averages, but this quarter uses daily averages. Some movement may come from that change in method. Where possible, use the new method for both periods. Show how the results differ from the old report. If the older detail is unavailable, state the break in the series.
Consider a separate example with a 90-day cost of goods sold of CU900,000. Both opening and closing inventory are CU300,000. The simple average is therefore CU300,000, giving 30 inventory days.
Suppose detailed records instead show average inventory of CU300,000 for the first 30 days, CU600,000 for the next 30, and CU300,000 for the final 30. These are averages within each block, not three isolated month-end balances.
Time-weighted average inventory = (300,000 × 30 + 600,000 × 30 + 300,000 × 30) ÷ 90 = CU400,000.
Using that average gives CU400,000 ÷ CU900,000 × 90 = 40 days. The two-date average missed the inventory peak. It understated the period's inventory days by ten.
Use daily balances when available and reliable. For samples taken at other intervals, consider the time each balance represents. An unweighted mean of unequal periods can produce another distortion. Explain the approximation rather than presenting a month-end sample as a daily average.
OpenStax's working-capital chapter describes the changing needs caused by seasonality and growth. That is why a quiet month should not be treated as the normal funding level for a peak production period.
Keep inventory value separate from physical waiting time
The factory's average inventory is CU405,000. It includes raw materials, partly completed garments and finished goods. These stages carry different costs. A finished garment contains more conversion cost than its fabric did when it entered stores.
The IFRS Foundation's IAS 2 overview explains the costs included in inventory. They cover purchase and conversion costs. For measurement, it uses the lower of cost and net realisable value. Those accounting features affect a value-based ratio.
Do not call CU225,000 of raw materials divided by total cost of goods sold the measured time fabric spends in stores. For a stage measure, use that stage's inventory and its relevant consumption or cost flow. State how the measure is defined. For actual waiting time, use dated lot records.
Likewise, a write-down can lower reported inventory without moving a single roll. That can lower DIO, but it has not produced cash. A cost change can move the ratio even when quantities and storage days stay the same. Review quantity, age, quality status, and value together.
For trim stocks, ApparelDiary's reorder-point guide links stock decisions to demand and the conditions for replenishment. A finance target for lower inventory should be tested against those operating needs. Some shortages can stop production. Cutting every item's stock by the same percentage ignores that risk.
Translate an improvement into money by component
Return to the main factory case. Suppose a review supports three targets at unchanged sales and cost rates. DIO falls from 45 to 40 and DSO from 36 to 32. DPO rises from 27 to 30. Assume the supplier has agreed to the revised terms. The lower stock level must also be achievable without disrupting orders.
The target cycle is 40 + 32 − 30 = 42 days, a reduction of 12 days. The associated balance changes use three different daily rates.
Proposed change | Matching daily rate, CU | Change in average balance, CU |
|---|---|---|
Inventory reduced by 5 days | 9,000 cost of goods sold | 45,000 lower inventory |
Receivables reduced by 4 days | 12,000 credit sales | 48,000 lower receivables |
Payables extended by 3 days | 6,000 credit material purchases | 18,000 higher payables |
The selected operating working-capital requirement falls by CU111,000. Target balances are CU360,000 of inventory, CU384,000 of receivables, and CU180,000 of payables. Their net is CU564,000, which is CU111,000 below the original CU675,000.
Multiplying the whole 12-day reduction by daily cost of goods sold would give CU108,000. That would be wrong for this case. Receivables use the sales rate, while payables use the credit-purchase rate. The separate balance bridge preserves those differences.
This estimate assumes steady rates and lower operating funding needs. It does not promise CU111,000 in the bank tomorrow. Inventory must be used or sold, future buying adjusted, and receivables collected. Discounts, stock disposal losses, and financing charges can change the net benefit. The dated cash forecast must show those effects.
Allow for growth even when the days do not change
A stable cycle can accompany a rising need for money. Suppose the main example's sales, cost of goods sold, and credit material purchases all rise by 20%. Assume the same prices, mix, credit share, and operating days for this simplified comparison.
The new daily rates are CU10,800 for cost of goods sold, CU14,400 for credit sales, and CU7,200 for credit material purchases. Maintaining 45, 36, and 27 days requires average balances of CU486,000, CU518,400, and CU194,400 respectively.
Net operating working capital becomes CU486,000 + CU518,400 − CU194,400 = CU810,000. That is CU135,000 more than before, although CCC remains 54 days. Growth has increased the size of the cycle without changing its length.
Real expansion is seldom this even. Fabric may be ordered well before the extra sales, and supplier terms may tighten as exposure rises. Use the ratio model to identify the likely pressure, then build the purchase, shipment, collection, and payment dates. A good historical ratio does not finance a new order by itself.
Read the exclusions before comparing factories
Customer deposits and supplier advances affect cash but do not fit neatly into the three balances used here. Show them separately rather than hiding them by netting unrelated accounts. Consider two factories with the same DIO, DSO and DPO. If one receives large buyer advances, its funding needs may be very different.
There can also be a distinction between a receivable and a contract asset. For example, the XRB publishes NZ IFRS 15. Paragraphs 105–108 distinguish an unconditional right to payment from other contract positions. Ask finance to map the actual accounts before building a collection measure. Use the factory's reporting framework.
Keep the treatment of doubtful balances clear. A lower receivable balance caused by a write-off is different from one reduced by a customer's payment. Reconcile cash collections and adjustments separately when judging collection performance.
An apparent negative cycle also needs context. With 20 inventory days, ten receivable days, and 45 payable days, CCC is minus 15 days. The defined supplier-credit period exceeds the other two periods combined. That does not guarantee enough cash for payroll, debt payments, taxes, or equipment. Nor does it prove that overdue supplier balances are healthy funding.
Match the measure to the production model
Two garment factories may handle the same number of metres while funding very different assets. In a full-package arrangement, a factory may buy its fabric and trims. In a cut-make-trim arrangement, the buyer may retain ownership of supplied materials. The contract and actual accounting determine what the factory records.
Buyer-owned fabric may be stored on site. That alone does not justify adding its full market value to the factory's inventory. That would change the financial ratio without establishing that the factory funded that asset. Track custody, loss exposure and stock accuracy separately. Finance should identify which costs belong in the accounts.
The reverse mistake is to omit factory-funded work merely because the buyer supplies fabric. Labour and other production costs may still tie up funds before the factory earns or collects its service fee. Use balances and flows that reflect the actual business model. Review that difference before borrowing a full-package factory's target.
Outside processing creates another boundary to check. Goods sent for printing or washing may still form part of the factory's recorded inventory. A location change alone does not prove a sale or a release of working capital. Reconcile goods held off site with the accounts and with the relevant supplier records.
Compare like periods as well as like models. One factory may be finishing a large seasonal programme. Another may be building stock for the next one, with quite different balances. A fair comparison needs the order stage, credit terms and inventory basis. Without them, a timing difference may look like poor performance.
Turn the ratio into operating questions
Investigate the largest component and its cause before setting a blanket target. High raw-material stock may reflect a long replenishment lead time, a minimum order, or goods bought for a cancelled style. High finished-goods stock may reflect an agreed shipment date or a quality hold. Those causes need different action.
DSO should lead to a customer-level review of terms, invoice dates, due dates, disputes, and actual collections. Thirty-six days may be acceptable under one agreement and late under another. An average cannot identify the overdue invoices on its own.
Separate document delays from credit delays. An invoice or required shipping document may have been sent late. The agreed payment clock may then start later than the dashboard assumes. Check the contract's trigger and the actual evidence. This helps locate where the delay began. It may have started before a valid payment request reached the buyer.
For DPO, distinguish agreed credit from overdue payment. Extending terms through negotiation is different from missing a due date. Check the effect on price, discounts and supply reliability. Consider the supplier relationship too before calling the increase an improvement.
The ACT's cash-cycle explanation stresses the need for suitable inventory levels. It also explains why a simple ratio needs operating detail. Without that detail, a stock cut may free cash but stop a production line. The interruption could cost more than the saving.
Make each monthly comparison reproducible
Keep a short note of the reporting period, day count and included accounts. Add the flow definitions, average method and exclusions. Preserve the source extracts. When a definition changes, explain its effect. Restate the comparison period if the data permits.
Review the three components, their money balances, and the underlying operating causes together. A dashboard can show an improving total while one customer debt worsens and a supplier balance becomes overdue. ApparelDiary's KPI dashboard guidance provides a useful basis for assigning an owner and a decision to each measure.
The final check is practical: can the team explain why the number moved and what cash event should follow? A genuine reduction in excess stock should change purchasing needs. Faster collection should appear in bank receipts. Agreed supplier terms should appear in the payment schedule. Linking the ratio to those events turns a reported cycle into a useful factory decision.
