The reviewing party is looking for whether supplier payments follow a documented terms policy or the current week's cash position. Absent that policy, a reported DPO is treated as a result without continuity, and the working capital adjustment gets calculated on the buyer's own assumption rather than the seller's history. *In most companies, days payable is not a written policy but a decision made each morning by whoever looks at the bank balance before releasing the payment run. A diligence team detects that difference within the first week, and once detected, it prices not the ratio itself but the management capacity standing behind it.* --- On whichever morning the supplier payment run is scheduled, someone opens the bank account, looks at the balance, and shortens the list accordingly. What governs that decision is rarely the invoice due date; more often it is the balance visible that morning, the expected timing of the next collection, and how insistent a given supplier was on the telephone the previous afternoon. Within the same company, two suppliers holding identical contractual terms may be paid at forty days and at seventy-five days respectively, the explanation residing not in the contract but in the history of the relationship and the tone of the last call. When payables turnover is computed at year end, a perfectly reasonable average emerges, and that average is presented in management reporting as though it were the output of a policy — when what stands behind it is not a policy at all, but fifty-two separate weekly judgements. The mechanism underneath this behaviour is not negligence; under certain conditions it is an entirely functional shortcut. Where cash inflow is unpredictable, tying payment to a single centralised intuition is the fastest and lowest-cost form of coordination available, whereas operating a distinct terms rule for each supplier presupposes both a system and a staffing layer, neither of which exists in the early stages. The shortcut produces the right answer while the company remains small, since the person controlling payments knows personally which suppliers will tolerate delay, which will halt shipment, and which will wait another week — knowledge that never enters any schedule. The difficulty lies not in the shortcut itself but in its persistence after the conditions change: once the supplier base triples, procurement disperses across locations, and the person releasing payments is no longer the founder, that personal knowledge ceases to be transferable. Knowledge that cannot be transferred occupies, in the eyes of a reviewing party, the same status as knowledge that does not exist. The question posed at the diligence table therefore takes the form of a question the company has never put to itself: by whom, and on the basis of which document, are payment terms determined. What is being asked is not the number of days of DPO — that figure can be derived from the trial balance without assistance — but whether the figure is the outcome of a decision or the average of a residue. Three kinds of answer are offered in response, and they are sharply distinct: a verbal assertion, a schedule unsupported by any board-level approval, and a dated, approved policy document defining terms bands by supplier segment. Answers falling into the first two categories are not treated as verifiable, which does not imply that they are untrue, only that their repeatability after closing cannot be demonstrated. On the documentation dimension, what is sought is not the existence of a text but the degree to which the text corresponds to observed practice. Where a policy file defines a standard forty-five-day term while purchase orders carry thirty days, supplier framework agreements carry sixty, and actual payment records scatter across a wide band, the resulting picture generates a weaker signal than the absence of any policy at all, since the gap between document and practice establishes a presumption that the same gap will be found in inventory, quality and human resources processes. At this point the reviewing party samples: a random group is drawn from the payments of a consecutive period and each is reconciled against contractual terms, invoice date and actual settlement date. What matters is less the magnitude of the deviation than its explicability — where a supplier has been paid early, the record should disclose whether the reason was a cash discount or shipment pressure. Measurement is the dimension most frequently left empty in this area. Most companies compute DPO at period end, whereas the indicator carrying managerial value is not the period-end average but the volatility across periods. Between two companies both averaging fifty-five days, one moving within a narrow band of fifty-three to fifty-seven each month and the other oscillating between thirty and eighty, the quality of working capital management is not remotely equivalent, and that distinction disappears entirely inside a single average. Volatility is itself a diagnosis: a wide band demonstrates that payment is governed by the cash position of the period rather than by a rule, which is to say the policy is not being applied. Where the ageing of overdue balances as a share of total trade payables is additionally untracked, a lengthening DPO cannot be separated into a negotiated gain and an accumulation of arrears; both post to the same line on the balance sheet, yet one represents bargaining power and the other supply chain fragility. The balance sheet consequence of this tendency is usually concealed not in the trade payables line itself but in the distance between that line one year earlier and one quarter later. When a normalised working capital target is set in a transaction moving toward closing, the buy-side looks for a reference level; absent a policy document and a consistent record of application, that reference is computed on the buyer's own assumption rather than on the recent period the seller presents. The buyer's assumption is conservative in a predictable way: terms deliberately stretched ahead of closing are assumed to normalise afterwards, generating a post-closing cash outflow. That adjustment is deducted directly from price or absorbed into a larger escrow, and in either configuration the amount leaving the seller's pocket is the cost of a policy document that was never produced. A second channel of cost is the invisible price component embedded in extended terms. In a company transacting with suppliers who offer cash discounts, delayed payment accumulates not in financing expense but in material cost; the forfeited discount flows straight into gross margin and reads, in margin analysis, as an operational weakness. When this linkage is established during review, the resulting picture operates in two directions at once — the reason for depressed margin is explained, while it is simultaneously established that the company does not track which line items drive its own cost structure. The same mechanism operates in reverse as well: a cash position protected through aggressive term extension returns on the supplier side as price increases, loss of allocation priority, or demands for security, and because that return is typically lagged, it lands in the post-closing period. On the ownership dimension, what is sought is not a name but a boundary of authority. Where it is undefined up to which amount and at which level payment approval is granted, whose approval is required to depart from standard terms, and on what stated basis and with what record an early payment may be released, responsibility settles in practice on whoever executes the payment run — most often the founder, or a manager reporting directly to the founder. That concentration is written straight into the founder dependence section of the review, because knowledge of the payment decision, together with the real hierarchy of supplier relationships, resides in a single person's memory. What an investor weighs here is not a question of character but one of transferability: whether payment decisions can be made at the same quality once that person is no longer at the table six months from now. Continuity sits one level beyond ownership and is tested by a single measure: whether the policy survives the departure of the person who wrote it. The indicators are ordinary but seldom present — terms conditions held as a field in supplier master data, the payment run executed on a fixed calendar under dual authorisation, exceptions collected in a separate register alongside their stated justification, and that register reviewed on a defined cycle. Where these four elements coexist, DPO is no longer the residue of one person's intuition but an output the company can reproduce; where one is missing, the system reverts to the individual precisely at the point of absence. The reviewing party is looking for exactly that point of reversion, since it marks where scaling will break. BEIREK's intervention in this area does not begin with drafting a policy text; it begins with mapping actual behaviour. All supplier payments over a defined historical window are matched along three axes — invoice date, contractual terms, actual settlement date — suppliers are grouped into bands according to observed payment behaviour, and the resulting distribution is decomposed into the portion explained by deliberate choice and the portion explained by cash constraint. On top of that map, a terms matrix differentiated by supplier segment is constructed, since a single sole-source critical supplier, a substitutable input, a services purchase and a discount-offering vendor cannot reasonably share one terms rule, and the matrix is bound together with approval authority thresholds into a single approved document. The rhythm operated after the document is what determines whether the result holds. The weekly payment run proceeds on a fixed day against a defined preparation list, every payment departing from standard terms drops into an exception register together with its justification, and that register is reviewed monthly alongside the cash flow projection. On the measurement side, two indicators are added beside period-end DPO: the width of the monthly DPO band, and overdue trade payables as a share of total trade payables. Taken together, these three convey to a reviewing party what a single average never can — that payment timing is managed as a decision, and that the decision is anchored to a mechanism rather than to a particular individual. Payment terms constitute the component of working capital most easily manipulated and most difficult to defend; the desired level can be reached within a single quarter, yet the proposition that the level will hold after closing can be demonstrated only through the existence of a policy, a record, and a distribution of authority. Here as elsewhere, what determines a company's valuation is not the reported figure itself but the ability to establish that the figure is reproducible independently of the founder. The question waiting at the next diligence table will be this: if last year's payment period was the product of a choice, who made that choice, and against which document. ## Key Points - In many companies whose average payment period looks entirely healthy, each individual payment decision rests on that week's cash balance rather than on any written terms policy. - A diligence team pays closer attention to the volatility of DPO across periods than to its level, because a wide monthly band is the most direct evidence that a person, not a rule, is governing the payment run. - When normalised working capital is negotiated ahead of closing, a DPO unsupported by a terms document is re-based on the buyer's assumption, and that adjustment comes out of the purchase price or enlarges the escrow. - The concealed cost of stretching terms is the forfeited early-payment discount, which accumulates in material cost rather than in financing expense and therefore distorts gross margin analysis. - Concentrating payment authority in one individual produces founder dependence; until ownership is distributed and documented, DPO cannot be treated as a repeatable institutional capability. ## Questions ### Is there a single correct answer to the question of how many days payment terms should be? No single correct figure exists; sector, supplier bargaining power and the substitutability of the input define the band. What a diligence team seeks is not an ideal number but whether the existing number rests on a policy. The same DPO level reads as robust when produced by a documented terms matrix and as fragile when produced by the weekly cash position. ### How does stretching payment terms before closing affect the working capital target? Deliberate pre-closing extension is read on the buy-side as a temporary accumulation of cash and is corrected when the normalised working capital target is computed. The buyer assumes stretched terms will revert after closing and generate an outflow, and that assumption is deducted from price or absorbed into a larger escrow. Without a consistent long-term record, contesting the adjustment is difficult. ### Which indicators should be tracked for payment terms? Period-end DPO alone is insufficient. Two indicators belong beside it: the band across monthly DPO values, meaning volatility, and overdue trade payables as a share of total trade payables. The first reveals whether payment follows a rule or the cash position; the second separates a lengthening DPO into a negotiated gain and an accumulation of arrears. ### What is the hidden cost of extending payment terms? With suppliers offering cash discounts, late payment means the discount is forfeited, and that loss accumulates in material cost rather than in financing expense, surfacing in gross margin as an apparent operational weakness. The second cost is lagged: it returns on the supplier side as price increases, loss of allocation priority or demands for security, typically landing in the post-closing period. --- Source: https://www.beirek.com/en/blog/days-payable-outstanding-diligence Publisher: BEIREK LLC — https://www.beirek.com
