The working capital it is one of the most relevant (yet most underestimated) financial concepts in business management. Although it is usually associated with accounting and short-term liquidity, in reality it is a strategic factor that can drive or destroy value, depending on how it is administered.
The working capital is usually a critical element both in mergers and acquisitions processes as in in-depth financial evaluations. It’s not just about “having cash,” but about understanding how daily operations are financed and how efficient that use of resources is.
In this article we will address the working capital concept, its main components, practical examples, and, above all, how to best manage it to strengthen liquidity, optimize profitability, and protect the company's value.
What is working capital?
The working capital it is difference between current assets and current liabilities of a company. In simple terms, it represents the resources available to finance the daily operation of the business once short-term obligations have been covered.
The current assets include accounts receivable, inventories, cash, and other assets expected to be converted into cash in less than a year. Meanwhile, the current liabilities consider accounts payable, short-term financial obligations, taxes payable, and other liabilities due in the same period. The difference between the two reflects the “financial cushion” the company has to operate.
A positive working capital indicate that the company can cover its short-term obligations without major difficulties. However, excessively high working capital can also be a sign of inefficiency: oversized inventories, poorly managed accounts receivable, or idle resources that could be invested in more profitable opportunities.
While the accounting definition is clear, in valuation contexts and strategic financial analysis, an adjusted version is often used: the operating working capital. This excludes items such as excess cash or financial investments that are not directly part of the business's operating cycle.
The reason is simple: the box that generates a reasonable financial return (for example, invested in low-risk instruments) does not necessarily reflect the operational efficiency. Instead, inventory and accounts receivable are directly linked to the sales and production cycle, and therefore directly impact the company's free cash flow.
At due diligence processes or in valuations under methodologies such as discounted cash flow (DCF), the operating working capital acquires special relevance. Variations in this variable can significantly modify the estimated value of a company, especially in high-growth businesses where working capital tends to expand rapidly.
For truly understand how working capital works within a company, it is essential to break it down into its main components. It is not enough to know the difference between current assets and liabilities; It is necessary to understand what items make it up and how they interact with each other. and in what way do they affect the liquidity and financial risk of the business.
Each of these elements —accounts receivable, inventories, and accounts payable— is part of the operating cycle and it has a direct impact on cash flow. A variation in any of them can improve or strain the company's financial position. Therefore, their analysis should not be limited to accounting, but rather integrated into strategic management and short- and medium-term financial planning.
Accounts receivable
The Accounts receivable represent sales made., but not yet collected. They are a current asset, but they also imply implicit financing granted to customers. The longer the payment terms, the greater the capital the company must tie up to sustain its operations.
An overly flexible credit policy can boost sales growth, but at the same time strain liquidity. Conversely, excessively restrictive policies can affect competitiveness. Balance is key, and it must align with the company's commercial strategy and financial structure.
The key indicator to monitor this variable is the Days Sales Outstanding (DSO), what does the number measure average number of days it takes for a company to collect payment to its customers after making a sale. It is calculated by dividing accounts receivable by average daily revenue.
A High DSO indicates that the company is financing its customers for prolonged periods, which puts pressure on liquidity even when sales are strong. Comparing DSO against agreed credit terms makes it possible to detect collection problems early, and tracking it over time helps evaluate whether changes in commercial policy are having the expected effect on cash flow.
It is important to keep in mind that Offering credit to customers is not a neutral decision: it has a real cost for the company. While waiting for payment, you must fund that capital with your own resources or debt, which connects directly to its discount rate or cost of capital. In other words, “selling on credit” is not free, and that cost must be integrated into the analysis of the commercial policy.
Portfolio quality is equally decisive. Not all customers should receive the same terms: segmenting by payment history, volume, tenure, or industry makes it possible to fine-tune credit policy and consciously manage risk. Having accounts receivable with low delinquency is not the same as having a deteriorated portfolio that will eventually require provisions or write-offs.
Inventories
The inventory is one of the main working capital “consumers”, especially in industrial companies, retail, or distribution. Maintaining adequate levels is essential to avoid stockouts, but excess implies financial costs, storage, obsolescence, and risks of deterioration.
The Efficient inventory management requires demand planning, coordination with suppliers and adequate control systems. Indicators such as inventory turnover make it possible to evaluate how quickly the company converts its stock into effective sales.
Holding inventory has a cost that goes beyond storage and obsolescence. The so-called holding cost also includes the opportunity cost of tied-up capital, insurance and shrinkage. Understanding this is key to realizing why reducing excess inventory is a financial decision, not just an operational one: every day of extra stock comes at a price that directly impacts free cash flow.
However, the objective is not to minimize inventory at any cost. A stockout has consequences that go far beyond the lost sale: damage to customer relationships, loss of market share, and emergency sourcing costs. The goal is to optimize the inventory level, not to reduce it indiscriminately.
In businesses with high seasonality, inventory can vary considerably throughout the year, which implies more sophisticated financial planning to avoid liquidity strains during periods of highest accumulation.
Accounts payable
The Accounts payable represent a source of spontaneous financing.. By negotiating longer terms with suppliers, the company can finance part of its operations without resorting to bank debt.
However, aggressively extending payment terms can damage commercial relationships or involve the loss of early payment discounts. Efficient working capital management is not about “paying as late as possible,” but rather about structuring agreements that generate a balance between liquidity, costs, and strategic relationships.
The key indicator to monitor this variable is the Days Payable Outstanding (DPO), which measures how many days on average does the company take to pay its suppliers. It is calculated dividing accounts payable by average daily cost of sales. A A high DPO indicates that the company is leveraging its suppliers' credit as a source of financing, which is positive to the extent that it does not generate trade frictions or the loss of preferential conditions.
A factor thThe risk of supplier concentration is often underestimated. If the company depends on a few critical actors, negotiating deadlines aggressively can be especially risky. It is advisable to distinguish between strategic suppliers, with whom the long-term relationship has a value that should not be sacrificed, and more commoditized suppliers, where there is greater room to negotiate terms without compromising operations.
The correct management of these components does not simply imply reducing balances or accelerating collections in an isolated manner. It try to optimize the balance between growth, operational efficiency, and financial strength. A company can significantly improve its cash position by adjusting minor misalignments in any of these three fronts.
Understand in Depth in the components of working capital allows for the detection of improvement opportunities. that often do not require large investments, but rather more disciplined and strategic management. It is in that balance that a solid financial foundation is built that sustains growth and protects the value of the company in the long term.
Practical example: how working capital impacts liquidity
Let's imagine a company that generates $1.000 million in annual sales and is growing at an annual rate of 30%. At first glance, this growth seems like excellent news. However, if the company must finance 90 days of accounts receivable and maintain inventory equivalent to 60 days of sales, the required working capital will increase proportionally with growth.
This means that every additional peso in sales does not immediately translate into cash. Part of that growth must be financed with internal resources or debt. In high-growth scenarios, working capital can turn into a true “liquidity vacuum.”.
At valorization processes, this phenomenon is especially relevant. A company can show high margins and accelerated growth, but if it requires large working capital injections to sustain that growth, its free cash flow will be lower, negatively impacting its value.
Working capital and value creation
From a strategic perspective, the working capital management is directly linked to the business value creation. Reducing days sales outstanding, optimizing inventories, or negotiating better terms with suppliers can free up cash without the need to increase sales or reduce operating costs.
That free cash flow can be allocated to higher-return investments, debt reduction, or shareholder distribution. In other words, improving working capital is a way to generate value without altering the business model.
At mergers and acquisitions processes, working capital it also influences the structure of the transaction. Many transactions include price adjustments based on “normal” levels of working capital. If the company is delivered with working capital lower than agreed, the final price may be adjusted downward.
How to better manage working capital
The working capital management It requires a comprehensive approach that combines finance, operations, and business strategy. It is not merely an accounting exercise, but a cross-functional discipline that impacts the entire organization.
First of all, it is essential monitor key indicators like days of accounts receivable (DSO), days of inventory, and accounts payable (DPO). These indicators allow you to visualize the cash conversion cycle and detect opportunities for improvement.
Secondly, technology plays a central role. Enterprise resource planning (ERP) systems, data analysis tools, and process automation can significantly improve accuracy in inventory and collections management.
Finally, organizational culture is decisive. If the sales department is only evaluated by sales growth, without considering portfolio quality or collection terms, working capital is likely to deteriorate. Incentives must be aligned with comprehensive value generation.
Common mistakes in working capital management
One of the most frequent errors is confusing profitability with liquidity. A company can be profitable in accounting terms and still face cash flow problems due to poor working capital management.
Another common mistake is failing to adequately project the impact of growth. Many companies celebrate increased sales without realizing that this growth will require additional financing to sustain inventories and accounts receivable.
Finally, underestimating working capital in valuation processes can generate unpleasant surprises. An incorrect adjustment can overestimate the available cash flow and, consequently, the value of the company.
Working capital as a strategic tool
The working capital it is not simply a accounting indicator; It is a strategic tool that directly impacts liquidity, financial risk, and value creation. Efficient management makes it possible to free up resources, reduce dependence on external financing, and strengthen the company's competitive position.
In contexts of growth, restructuring, or M&A processes, its impact becomes even more critical. Understanding how working capital behaves, how it is projected, and how it is optimized is essential for making informed and strategic decisions.
