Cash Conversion Cycle (CCC)
The cash conversion cycle measures how many days your money is tied up in the business between paying for something and getting paid for it. It is the sum of how long inventory sits and how long customers take to pay, minus how long you take to pay suppliers. At Treewalk we calculate it on diligence engagements because it tells a buyer how much cash the business will swallow before it gives any back.
The three components
CCC is built from three day-counts:
Days sales outstanding (DSO).
Average days between making a sale and collecting the cash.
Days inventory outstanding (DIO).
Average days stock sits before it is sold.
Days payable outstanding (DPO).
Average days you take to pay suppliers.
Why it matters more in a transaction than in a management report
For an owner, CCC is a useful operating metric. In a deal it becomes a pricing input, because it drives how much working capital has to be left in the business at close.
A business with a long cycle needs a large permanent cash cushion just to keep running. A buyer has to fund that from day one, and it directly shapes the net working capital peg. Two businesses with identical earnings and very different cycles are not worth the same.
What we actually find when we calculate it
Stale receivables inflate DSO and mislead everyone
This is the most common distortion we see. A business never cleans its accounts receivable, so uncollectable invoices from years back sit in the ledger indefinitely. DSO looks terrible, and the working capital requirement looks larger than it truly is. On one engagement the receivables balance swung wildly across periods before dropping sharply, and the drop coincided with an accounting system change rather than any improvement in collections. The old balance had simply been carried forward incorrectly for years. That has a practical consequence for how we benchmark. Where the receivables history is that messy, a trailing twelve month average is not a reliable basis, and we will use a trailing three or six month figure instead so the peg reflects how the business currently operates. The same applies after any system migration.
A long DPO is not automatically a problem
Slow payment to suppliers shortens the cycle, and where a business has genuinely negotiated favourable terms that is a real advantage worth preserving. What matters is whether the terms are agreed or simply taken. Stretched payables that suppliers have not agreed to are a relationship risk that can snap back immediately after a change of ownership, when goodwill built by the old owner disappears.
Consignment inventory removes days from the cycle entirely
Where a business holds stock on consignment, it is not paying for that inventory until it sells. From a cash flow perspective that is a strong position, because the goods are available to pull whenever needed without tying up capital, and DIO effectively drops out.
Not every business has a cycle worth measuring
Businesses paid at the point of sale, or in advance, carry no meaningful receivables at all. On those engagements there is no DSO to worry about and no working capital metrics to calculate, and saying so plainly is more useful than producing the ratio for the sake of it.
Reading the number
| Pattern | What it usually means |
|---|---|
| High DSO, clean ageing | Genuinely slow-paying customers or generous terms |
| High DSO, old balances in the ageing | Uncollected debt never written off, not a collections problem |
| High DPO, agreed terms | A real advantage, and worth confirming it survives the sale |
| High DPO, no agreed terms | Stretched payables, a risk that resets on close |
| Low DIO with consignment stock | Favourable, and the reason should be stated explicitly |
| Negative CCC | Suppliers fund operations, usually subscription or prepaid models |
The pattern matters more than the number. A high DSO caused by three years of uncollected invoices is a cleanup exercise. A high DSO caused by customers who genuinely pay in 90 days is a permanent funding requirement, and only one of those is fixable.
Frequently asked questions
What is a good cash conversion cycle?
It depends entirely on the industry, so cross-sector comparisons are close to meaningless. Compare against the business’s own history and against how it is structured. The trend over time is far more informative than the absolute figure.
How is CCC different from working capital?
Working capital is a dollar amount at a point in time. The cash conversion cycle is a duration. They are linked: a longer cycle means a higher permanent working capital requirement, which is why we calculate both on a deal.
Can a business have a negative cycle?
Yes, and it is a strong position. Businesses that collect before they deliver, such as subscription or prepaid models, are funded by their own customers. That said, a negative cycle usually means substantial deferred revenue, which brings its own treatment questions in a transaction.
Should I improve my CCC before selling?
Cleaning up stale receivables is worth doing regardless, because it makes the numbers legible and shrinks an apparent working capital requirement that is not real. Artificially stretching payables in the months before a sale is a different matter and tends to be visible in diligence.
Which periods do you use to calculate it?
Usually a trailing twelve months, unless the history is distorted by a system change, a cleanup or heavy seasonality. In those cases a trailing three or six month basis reflects the business more honestly, and we will say so in the report.
Where to next
If your receivables have never been properly cleaned, your cash conversion cycle is probably telling you something untrue, and it will cost you at the negotiating table. Our transaction advisory services team calculates this on every engagement. Related reading: the net working capital peg it feeds into, and accounts receivable management for the collections side.
