For small and midsize businesses (SMBs), cash flow is often a more important indicator of financial health than profitability alone. Even growing, profitable businesses can face challenges if the timing of cash coming in and going out is not managed effectively. In our daily conversations, we hear how cash flow drives a business’s decisions on whether to accept new orders, expand or shrink spending, tap external financing, and, in some unfortunate cases, resort to high-cost merchant cash advances (MCAs).
In this post, we cover the key metrics every business should track, along with practical strategies to maintain healthy liquidity and support growth.
Key Metrics for Monitoring Cash Flow
One of the most important measures of financial health is Operating Cash Flow (OCF), which represents the cash generated by a company's core operations. OCF is heavily influenced by working capital—the liquidity required to fund day-to-day business activities such as payroll, inventory purchases, and overhead expenses.
Common measures of working capital efficiency include:
Days Sales Outstanding (DSO): The average number of days it takes to collect from customers. A high DSO means your customers are treating your business as a free credit line. Lowering your DSO will improve your cash position immediately.
Days Payable Outstanding (DPO): The average number of days it takes you to pay your vendors. A low DPO means you may be draining your cash too quickly. Strategically managing your DPO without harming vendor relationships helps optimize your cash position.
Cash Conversion Cycle (CCC): The number of days you need to fund normal business operations out of your own cash reserves before you’re able to replenish them with collections.
Alongside calculating these metrics, it is critical to conduct frequent cash flow planning to project your cash balance, accounting for any seasonality and lumpy outflows. For longer-term strategic planning to inform hiring, CapEx, or capital raise decisions, you should look 6 to 12 months ahead in your projections. In addition, regular comparisons of actual cash versus your projections will help you identify gaps and address them proactively.
Best Practices We’ve Seen
In our experience, the best financial and business outcomes are driven by proactive cash flow management. Here are some best practices we’ve observed in small and midsize businesses:
Match the duration of capital with the cash flow need. Term loans and equity raises should be used for longer-term expenditures, such as personnel or capital investments. For working capital needs where a business is trying to fill a short-term cash gap—such as making payroll by month-end before accounts receivable (A/R) is collected—using a credit line or early payment program will be most cost-effective, as those can be repaid once revenue is collected.
Set up contingency capital before emergencies arise. It is always best to secure capital while your cash position is strong. Going through onboarding and underwriting processes with lenders and factors can be laborious and time-consuming. Furthermore, your business’s financial health will directly impact approval decisions and your cost of capital. Businesses that establish contingency capital strategically do so from a position of strength.
Understand the true cost of customer-sponsored early payment programs. We have seen programs ranging from being extremely supplier-friendly to those that treat suppliers as a profit center for the customer’s own treasury management functions. Accessibility is also often a problem for smaller businesses, as many of these programs are only available to larger, strategic suppliers.
Leverage your niche. If your business operates in a niche space with a highly differentiated offering, use that leverage to negotiate better payment terms with your customers. We frequently see this in custom manufacturing, creative businesses with tremendous founder brand equity, and service providers using specialized equipment.
Use receivables finance to bridge the gap. If negotiating terms is difficult or puts you at a competitive disadvantage, don’t fight the terms; instead, consider using receivables finance to bridge the short-term gap. While it is not the least expensive option, businesses often find that the return from winning new business easily exceeds the cost of capital.
