Introduction
Accounts payable is the most under-utilized cash flow lever in most product-based businesses. Unlike receivables -- where the cash is owed to you and you have to chase it -- payables represent cash that is still in your account. The timing of when it leaves is, within the bounds of your supplier agreements, within your control. Yet most businesses do not manage that timing deliberately. They pay invoices when they arrive, on a weekly check run, or whenever the owner reviews the accounts payable stack -- a pattern that often results in paying significantly earlier than supplier terms require.
The Financial Models Lab analysis of DPO optimization in 2025 and 2026 describes the opportunity directly: in a persistent high-interest environment, every day you retain cash before paying an invoice is a financial advantage -- allowing you to reduce reliance on expensive short-term credit or strengthen your cash buffer. Businesses that manage payables strategically are effectively using the interest-free credit that their suppliers have already agreed to extend, rather than voluntarily surrendering it.
The distinction that the owner in the opening question is asking about is the right one. There is a significant difference between stretching payables -- paying beyond agreed terms, which damages supplier relationships and creates supply chain risk -- and optimizing payables -- paying at the end of the terms your suppliers have agreed to, which is precisely what those terms are designed to provide. The former is a business practice that erodes trust. The latter is sound working capital management that any well-run business should be doing.
According to Order.co's 2025 accounts payable management analysis, strong AP management maintains the flow of goods and services your business depends on while protecting working capital. The two goals are not in conflict -- they require the same discipline: paying on time, consistently, at the end of your agreed terms rather than early by default or late under pressure.
In this article I want to explain specifically how to implement a payables strategy that captures the available working capital benefit without creating any of the supplier relationship damage that the owner is rightly concerned about avoiding.
Why This Happens
Most businesses pay suppliers earlier than their terms require for three reasons. First, the payment process is on autopilot -- invoices are batched and paid on a regular schedule that does not distinguish between invoices due in 5 days and invoices due in 25 days.
Second, there is a psychological tendency toward payment speed -- many owners feel that paying quickly is a sign of financial strength and good faith, and they are not wrong.
But there is a meaningful difference between paying promptly and paying before it is required. Third, the working capital value of payables timing is not visible in the same way that receivables timing is. When a customer pays late, you feel it immediately. When you pay early, you do not feel the cost of the voluntarily surrendered float.
The result is a DPO (Days Payable Outstanding) that is significantly shorter than the available terms. For a business with $3M in annual purchases, the difference between an average payment timing of 20 days and the available term of 38 days is approximately $150,000 in cash that is voluntarily leaving the account 18 days earlier than required.
That $150,000 is not earning a return. It is not reducing debt. It is just in a supplier's account rather than yours -- because the payment process was not designed to use the full term available.
Business Impact of Unmanaged Payables Timing
The consequences of paying significantly earlier than terms require are specific and compounding.
Working capital is reduced unnecessarily
Every dollar paid earlier than required reduces the working capital available for operations, growth, and reserve building. For a manufacturing business with $4M in annual purchases paying an average of 18 days before terms require, approximately $200,000 in working capital is chronically volunteered away. That $200,000 -- if retained until terms require payment -- could cover additional inventory purchases, fund a growth initiative, or build toward the operating reserve the business needs to be in GREEN cash flow state.
Line of credit is drawn while cash is being sent out early
This is the most counterproductive pattern in AP management: a business simultaneously drawing on its line of credit for operational needs while paying suppliers 2 to 3 weeks before required. The interest being paid on the line of credit is a direct consequence of the early payment pattern -- the business is borrowing money to cover operational needs while voluntarily sending working capital out the door ahead of schedule. Aligning payment timing with terms would eliminate or reduce the need for line of credit draws in many businesses.
The opportunity to negotiate better terms is not being taken
Businesses that reliably pay at or close to agreed terms have stronger relationships with suppliers than businesses that pay erratically -- either very early or sometimes late. That relationship strength is a platform for negotiating improved terms: extended payment windows, higher credit limits, favorable pricing for volume commitments, or priority allocation during supply constraints. A business that has been paying 20 days early with a supplier for 3 years has built significant goodwill that could be converted into a formal extension of terms -- adding 15 to 20 days to the payment window as an agreed, contracted benefit rather than a unilateral decision.
The Payables Strategy Framework
A strategic approach to accounts payable has four components. Each one adds working capital value while maintaining or strengthening supplier relationships.
Component 1: Know your current DPO and the gap to available terms
Start by calculating your current DPO: accounts payable balance divided by daily purchases (annual purchases divided by 365). If your payables balance is $280,000 and annual purchases are $3.5M, your DPO is approximately 29 days. Now compare that to your weighted average supplier terms. If your standard terms across suppliers average Net 42 days, you have a 13-day gap between your current payment timing and what your terms provide. On $3.5M in annual purchases, that 13-day gap represents approximately $125,000 in working capital that could be retained until terms require payment.
This calculation is the starting point for payables strategy. It tells you the scale of the opportunity and gives you a specific target: move from a DPO of 29 days to a DPO of 38 to 40 days (slightly below the full term to maintain a buffer against processing delays) and capture the available working capital benefit.
Component 2: Segment suppliers and set payment timing by segment
Not all suppliers warrant the same payment timing strategy. Segment your suppliers into three categories. Strategic suppliers -- those whose relationship quality, product quality, or supply reliability are critical to your operations -- deserve the most attentive payment management. With these suppliers, consistency and predictability of payment (at or near their agreed terms) is more valuable than extracting maximum float. Paying reliably at day 30 on a Net 30 term supplier is the foundation of a strong relationship.
Standard suppliers -- the majority of your supply base -- should be paid at or close to their agreed terms, not before. A systematic payment process that queues payments for approximately 3 to 5 days before the due date ensures timely payment without volunteering excess float. Opportunistic suppliers -- vendors with standard catalog terms where no ongoing relationship investment is required -- can be managed at the full extent of available terms without any relationship consequence.
Component 3: Evaluate early payment discounts with the actual cost calculation
Many suppliers offer early payment discounts: a typical structure is 2/10 Net 30, meaning a 2% discount is available if payment is made within 10 days rather than 30. Before accepting these offers, calculate the annualized cost of the discount. A 2% discount for 20-day earlier payment is equivalent to an annualized interest rate of approximately 36%. If your cost of capital -- the rate at which you finance working capital needs -- is below 36%, taking the discount is financially advantageous. If you have no working capital financing needs and strong cash reserves, the discount may be worth taking. But for businesses using a line of credit at 7 to 9%, the trade-off of giving up the 20-day float for a 2% discount is not always the right one, and many businesses take early payment discounts reflexively without calculating whether the trade makes financial sense.
Component 4: Negotiate extended terms with strategic suppliers where relationship supports it
For suppliers where the relationship is strong and the payment history is reliable, a direct conversation about extended terms is often more productive than it seems. Suppliers with whom you have a multi-year relationship of consistent, on-time payment at their current terms have specific reasons to consider an extension: you are a reliable customer they want to retain, the extended terms are a low-cost way for them to add value to the relationship, and the conversation itself signals that you are managing your business professionally rather than simply stretching payments reactively.
The conversation should be framed as a planned working capital management initiative -- you are formalizing what has always been an informal arrangement, extending from Net 30 to Net 45 or Net 60 for this supplier, with the same reliability of payment at the new terms. Approached professionally, this conversation succeeds more often than owners expect -- particularly with smaller suppliers who have a strong interest in maintaining a reliable, long-term customer relationship.
The Critical Distinction: Optimization vs. Stretching
The boundary between payables optimization and payables stretching is important to understand and respect. Optimization means paying at the end of agreed terms consistently -- using the credit period your supplier has contracted to provide. Stretching means paying beyond agreed terms -- taking credit the supplier has not agreed to extend. The practical difference:
• Paying on day 38 of a Net 40 term is optimization. The supplier agreed to wait 40 days. You are using 38 of the 40 days available. No relationship damage.
• Paying on day 50 of a Net 30 term is stretching. The supplier agreed to wait 30 days. You have taken 20 additional days of credit without agreement. This damages trust and may result in tighter terms, removal of priority status, or supply disruption.
• Paying on day 15 of a Net 30 term is early payment. You have voluntarily given up 15 days of float the supplier agreed you could retain. No relationship damage, but working capital unnecessarily surrendered.
The goal of payables strategy is to move from the third situation to the first -- paying at the end of agreed terms rather than before. Never from the first to the second. Optimization and stretching are not on a spectrum. They are categorically different practices with categorically different consequences.
Warning Signs That Payables Management Needs Attention
• Your average payment date is more than 10 days before the average due date across your supplier base. If this is the case, you are systematically surrendering float that your suppliers have agreed to provide.
• You are drawing on the line of credit while simultaneously paying suppliers significantly before terms. This is the most counterproductive payables pattern -- borrowing money to cover working capital needs while voluntarily sending working capital out ahead of schedule.
• You have never reviewed your supplier terms to understand what credit period each supplier has agreed to provide. If terms are not being tracked and payment is not being timed against them, payables management is happening by default rather than by design.
• You are taking early payment discounts reflexively without calculating the annualized cost. Some early payment discounts are financially attractive; others are not. Making the calculation before accepting ensures the decision is sound.
• You have not had a terms conversation with a key supplier in the last 2 years. Supplier terms are not permanent -- they are negotiable, and a relationship of consistent on-time payment is the platform for that negotiation.
What You Should Actually Understand About This
Accounts payable is the third leg of the working capital optimization triangle, alongside receivables and inventory. Receivables improvement brings cash in faster. Inventory optimization reduces cash tied up in stock. Payables optimization delays cash going out until it must. All three together produce the most significant working capital improvement available to a product-based SMB without new revenue or new financing.
The key insight that makes this work without relationship damage is the distinction between using terms and stretching them. Your suppliers have told you, in writing, that they will wait a specific number of days for payment. Using those days is not taking advantage of anyone -- it is accepting the commercial offer they have made. Paying before those days are used is a voluntary gift of working capital to your supplier that has no commercial justification and no relationship benefit that would not be equally well served by paying on the last day of the term.
In the Advisory Circle businesses where we implemented a deliberate payables strategy -- calculating the current DPO, identifying the gap to available terms, segmenting suppliers, and implementing a payment timing process aligned to terms -- the cash impact was typically the third-largest cash flow improvement after receivables and inventory. It required no customer interaction, no supplier negotiation (for the base case of simply paying at terms rather than before terms), and no operational change. It required only a deliberate payment scheduling process that aligned timing to terms. That is the definition of an available opportunity that is not being captured.
Key Takeaways
• Accounts payable optimization means paying at the end of agreed supplier terms -- using the interest-free credit your suppliers have contracted to provide -- not paying beyond those terms. The distinction is critical.
• Most SMBs pay significantly earlier than their terms require. The gap between current DPO and available terms represents real, recoverable working capital that is being voluntarily surrendered.
• The four-component payables strategy: calculate current DPO and the gap to available terms, segment suppliers and set payment timing by segment, evaluate early payment discounts with the actual annualized cost calculation, and negotiate extended terms with key suppliers where the relationship supports it.
• Optimization and stretching are categorically different practices. Paying at the end of agreed terms does not damage supplier relationships. Paying beyond agreed terms does. The strategy stays firmly in the first category.
• Payables optimization is the third leg of the working capital triangle alongside receivables and inventory. All three together produce the most significant working capital improvement available without new revenue or new financing.
Frequently Asked Questions
How do I calculate my current DPO?
Divide your current accounts payable balance by your average daily purchases (annual purchases divided by 365). For example: $320,000 in accounts payable divided by $9,589 in average daily purchases (based on $3.5M annual purchases) equals approximately 33 days DPO. Compare this to the weighted average of your supplier terms. If the average terms across your supply base are Net 45, a DPO of 33 indicates you are paying 12 days earlier than required on average -- a meaningful working capital improvement opportunity.
Will suppliers notice if I start paying closer to due dates?
They will notice in the sense that payments will arrive at a different point in the cycle than they previously did. What they will not experience is a breach of terms -- you are paying exactly when you agreed to pay. If a supplier has come to expect early payment as a pattern (rather than as a contractual right), the first few payments at the end of terms rather than early may prompt a check-in. In those cases, the conversation is straightforward: you are implementing more disciplined payment timing as part of your cash management, and you will be paying consistently at the terms agreed. That is a professional, reasonable explanation that should not create any relationship concern.
What is DPO benchmarking and how should I use it?
DPO benchmarking compares your DPO to industry averages and to what your specific supplier terms provide. Financial Models Lab's 2026 analysis shows significant variation by industry: technology companies may run DPO of 100-plus days due to their market power, while retailers typically run 50 to 60 days. For manufacturing and distribution SMBs, a DPO of 35 to 45 days is typical against standard Net 30 to Net 45 terms. The relevant benchmark for most SMBs is not the industry average but your own supplier terms -- the goal is to move DPO toward the average of your available terms, not to match large-company DPO levels that depend on market power you may not have.
Should I automate accounts payable?
AP automation -- tools that streamline invoice processing, approval workflows, and payment scheduling -- can add significant efficiency and control to the payables process. Planergy's 2025 analysis shows that AP automation reduces invoice processing costs by up to 76% and improves discount capture rates by 30%. For SMBs managing dozens of suppliers and hundreds of invoices monthly, automation can convert a time-consuming manual process into a managed system. The core payables strategy -- paying at terms, segmenting suppliers, evaluating discounts -- applies regardless of whether the process is manual or automated. Automation makes it more efficient; the strategy makes it more effective.
How does payables strategy interact with supply chain risk?
Paying reliably at agreed terms is actually a supply chain risk management strategy: it maintains the predictability and trust that keeps strategic suppliers prioritizing your orders. Stretching -- paying beyond terms -- creates supply chain risk by damaging the relationship with the suppliers whose reliability you depend on. Optimization -- paying at terms, not beyond -- is neutral to positive for supply chain risk because it demonstrates financial discipline without any breach of the agreement.
