The Cash Conversion Cycle: What It Is and Why It Affects Your Sale Price

Most founders who have built successful businesses have developed an intuitive understanding of cash flow. They know what their bank account looks like at the start and end of each month, they know when payroll goes out, and they have a sense of which customers pay slowly. What most founders do not have is a systematic view of the cash conversion cycle: the quantified relationship between billing, collecting, paying vendors, and managing inventory that determines how much working capital the business consumes and how much cash it generates from operations.

In an M&A context, this matters directly and measurably. The cash conversion cycle determines the working capital target that buyers set at closing, and the working capital targets determine how much of the headline enterprise value the founder actually receives. A business with a 65-day cash conversion cycle will have a higher working capital peg than the same business with a 45-day cycle, and the difference flows directly to the seller as reduced or increased net proceeds.

DSO, DPO, and DIO: what each component measures

Days Sales Outstanding (DSO) measures how long, on average, it takes the business to collect payment after revenue is recognized. DSO equals (accounts receivable / annual revenue) times 365. A business with $2M in accounts receivable and $12M in annual revenue has a DSO of approximately 61 days. If industry benchmarks for comparable businesses run at 40 to 45 days, the business has a DSO opportunity: tightening collections by 15 to 20 days would free up $500K to $650K in cash.

Days Payable Outstanding (DPO) measures how long the business takes to pay its vendors. DPO equals (accounts payable / cost of goods sold) times 365. Higher DPO is generally favorable to working capital because the business is using vendor financing rather than its own cash. However, artificially extending payables in the 60 to 90 days before close is visible to buyers and will be reversed in the working capital adjustment.

Days Inventory Outstanding (DIO) applies to product businesses and measures how long inventory sits before it is sold. DIO equals (inventory / cost of goods sold) times 365. Lower DIO is favorable: inventory converts to receivables and then to cash faster. High DIO indicates either slow-moving inventory, over-ordering, or insufficient demand relative to stock levels, all of which buyers view as working capital risk.

How CCC affects the working capital peg in M&A

The working capital peg is the mechanism through which the cash conversion cycle directly affects sale proceeds. In most M&A transactions, the purchase price is set at a defined enterprise value, with a working capital adjustment at closing that compares actual working capital at close to a target (the peg). If actual working capital exceeds the peg, the seller receives additional proceeds. If actual working capital is below the peg, proceeds are reduced.

The peg is typically set as the trailing 12-month average of normalized working capital. That average reflects the business's actual cash conversion cycle over the measurement period. A business that has improved its CCC, reducing DSO and DIO while maintaining DPO, over the 12 months before a process will have a lower average working capital requirement, which becomes the peg. At closing, the seller's obligation to deliver working capital equal to the peg is easier to meet, and excess working capital above the peg flows to the seller as additional proceeds.

Practical levers for each CCC component

Seasonal working capital variance and the peg negotiation

Many businesses have seasonal revenue patterns that create predictable swings in working capital. A landscaping company carries high receivables in summer and low in winter. A retail distributor carries peak inventory before Q4 and draws it down after. These seasonal patterns create a specific peg negotiation challenge: if the close date falls in a high-working-capital season, the seller must deliver a larger working capital amount. If it falls in a low season, the seller may receive excess proceeds above the peg.

Most boilerplate working capital peg language uses a trailing 12-month average, which smooths seasonal variation. But buyers who understand your seasonality often try to influence close timing or peg methodology to their advantage. A seller who closes in November for a business that peaks in December is handing the buyer a predictable favorable adjustment.

Connecting CCC improvement to pre-transaction preparation

CCC improvement is most valuable when it is implemented early enough that the improvement is reflected in the trailing 12-month average used to set the working capital peg. An improvement made 6 months before close will be partially reflected in the peg (the period of improvement overlaps with 6 of the 12 months in the trailing average). An improvement made 12 months before close will be fully reflected. An improvement made 6 months before close will be partially reflected in the peg (the period of improvement overlaps with 6 of the 12 months in the trailing average). An improvement made 12 months before close will be fully reflected.

This timing dynamic means that working capital management should be part of the transaction preparation plan that starts 18 months before a targeted close, not an afterthought in the 90-day pre-process sprint. The founders and CFOs who understand this achieve materially better working capital outcomes at closing than those who focus exclusively on the enterprise value negotiation.
