In every business, cash is more than a number on a balance sheet. It is the fuel that keeps operations moving, employees paid, inventory stocked, debt serviced and growth opportunities within reach. A profitable company can still struggle if its cash is tied up in receivables, excess inventory or inefficient spending. This is where the concept known as the “Power of One” becomes so valuable. The idea is simple: A single small improvement in a critical financial driver can have a surprisingly substantial impact on an organization’s cash position.
The Power of One works because cash flow is extremely sensitive to small operational changes. Reducing receivables by one day, carrying one less day of inventory, extending payables by one day or improving gross margin by one percentage point can all release meaningful amounts of cash. On their own, these changes may seem minor. Together, they can improve a business’ liquidity and reduce the need for external financing. This principle is especially relevant in the automotive industry, with its high operating costs and significant working capital demands, as well as in other inventory-heavy businesses.
A useful way to understand this is through the cash conversion cycle, which measures how long it takes for a business to convert investments in inventory and receivables into cash from customers. The shorter this cycle, the stronger the company’s cash position. The main components of the cycle are accounts receivable, inventory and accounts payable. The Power of One focuses on improving these drivers one step at a time, delivering immediate, measurable cash benefits.
One of the most important financial drivers is accounts receivable, often measured by Days Sales Outstanding (DSO). This tells a business how quickly customers pay their invoices. If a company shortens DSO by even one day, it frees cash that would otherwise remain tied up waiting for payment. For example, if annual credit sales equal $12 million, reducing DSO by one day unlocks about $32,900 in cash. A two-day improvement would double that effect. Businesses improve receivables performance by issuing invoices promptly, using electronic billing systems, consistently following up on overdue accounts, and making payments easier through digital options. Better collections do not just improve accounting metrics; they directly strengthen liquidity.
A second major driver is inventory management, commonly measured by Days Inventory Outstanding (DIO). Inventory is often one of the largest cash uses in an operation. Every extra day a product sits unsold means more money is tied up and unavailable for other needs. (Think about how much cash is sitting dormant in your parts department right now.) If a business has an annual cost of goods sold of $9 million, cutting inventory by one day can release roughly $24,700 in cash. Reducing inventory days by three or four days can quickly yield a six-figure cash improvement.
The solution is not simply carrying less inventory blindly but managing it more intelligently. Better forecasting, stronger purchasing discipline, tighter control of slow-moving stock and better coordination between departments can all reduce excess inventory while maintaining service levels and improving the customer experience.
The third working capital driver is accounts payable, measured by Days Payables Outstanding (DPO). Carefully extending payment terms allows a business to hold onto cash longer without damaging supplier relationships. If annual purchases or cost of goods sold total $9 million, improving DPO by one day preserves about $24,700 in cash. When a company negotiates better supplier terms, centralizes invoice approval and pays vendors on time but not prematurely, it improves its cash position while maintaining credibility. The goal is not to delay payments irresponsibly, but to manage them strategically.
Beyond working capital, gross margin is another powerful lever. Every improvement in pricing, product mix or cost control increases the cash generated per sale. In the dealership setting, this may mean improving front-end gross on vehicle sales, increasing F&I income or expanding higher-margin revenue streams such as service, parts, maintenance plans and warranties. A one-point gain in gross margin across a large revenue base can have a dramatic effect on cash flow. Unlike some cost-cutting measures, margin improvement strengthens both profitability and cash generation simultaneously.
Equally important is operating expense control. A business does not need to slash costs aggressively to improve cash flow; even a small reduction in controllable operating expenses can yield meaningful results. If annual operating expenses are $12.5 million, a 1% reduction adds $125,000 to cash flow. That could result from better procurement, lower utility usage, more efficient staffing, reduced overtime, fewer manual errors or process automation. The point of the Power of One is that management does not need to solve everything at once; one small, focused improvement can create momentum and immediate financial relief.
Another area often overlooked is capital expenditure and financing strategy. Timing matters. Delaying a non-essential purchase, choosing leasing over buying or negotiating better financing terms can preserve cash during tighter periods. For dealerships, financing tools such as floor plan arrangements, holdbacks, rebates and incentive structures can significantly affect liquidity. Good fiscal management means understanding not only profit on paper but also the timing of cash inflows and outflows.
You Know All of This, But Do Your Managers?
I would expect that dealers, CFOs and controllers already have a significant grasp on the points covered so far. But what about every operating manager in your dealership? In my experience, the further away from senior management one gets, the more opportunities there are for fiscal management education.
There is no time like the present to help your operational managers develop their potential in finance and cash management. One way to do it is to, during one of your regularly scheduled management meetings, ask each person to suggest:
- Ways to improve your sales cycle (in any/every department).
- Ways to improve your production/inventory cycle.
- Ways to improve your delivery cycle.
- Ways to improve your billing and payment cycle.
Be sure to implement suggestions such as shortening the cycle, eliminating mistakes and changing the process/model. Whatever the suggestions are, be sure to follow through and be specific about:
- What is to be done
- How to execute it
- When it should be done
- Who will be accountable for it
I recently led this exercise with a single-point domestic dealer client. At the end of the meeting, the team presented many suggestions that had never been discussed before, worth tens of thousands of dollars.
These ideas align strongly with the themes emphasized in the Finances chapter of “The Dealership Manifesto.” That chapter underscores the reality that cash is king and that disciplined fiscal management is essential for long-term success. It highlights the need to measure what matters, manage working capital tightly and understand where cash is won or lost in everyday operations. In dealership environments, this means watching inventory levels, controlling expense creep, improving service and parts profitability, and maintaining reliable cash flow forecasts. The book’s broader message is that strong financial performance does not happen by accident; it comes from consistent attention to the operational details that drive cash.
Conclusion
The Power of One is powerful because it is practical. It does not require dramatic restructuring or unrealistic targets. It asks leaders to identify one measurable financial driver, improve it slightly and track the result. Reduce receivables by one day. Cut inventory by one day. Improve margins by one point. Lower expenses by 1%. Each action creates cash. Once one gain is secured, the organization can move to the next level.
This mindset creates a culture of discipline and accountability. Small wins build confidence, improve financial visibility and strengthen resilience. Over time, these improvements compound into a healthier balance sheet, reduced borrowing needs and greater freedom to invest in growth. That is the real Power of One: a single operational improvement that leads to stronger cash, better decisions and a more durable business.
