Key Liquidity Ratios for Series A Due Diligence

Calculated by dividing current assets by current liabilities, this metric provides a broad view of a company's ability to cover short-term obligations with its short-term assets. Investors scrutinize this to ensure the startup has enough buffer to handle operational expenses without immediate external funding.

Also known as the acid-test ratio, this excludes inventory from current assets to provide a more conservative measure of liquidity. It reveals whether a startup can meet its immediate liabilities using only its most liquid assets, which is crucial for SaaS or service-based models with minimal inventory.

The most conservative liquidity ratio, it compares cash and cash equivalents directly to current liabilities. While rarely optimal for growth startups, investors check this to understand the minimum safety net available during severe market downturns or funding delays.

This measures the proportion of current liabilities covered by operating cash flow. It demonstrates whether the core business operations generate sufficient cash to pay off short-term debts, indicating genuine operational health rather than just accounting asset valuations.

Representing the difference between current assets and current liabilities, working capital is a fundamental indicator of short-term financial health. Positive working capital suggests the company can fund its day-to-day operations and invest in growth, while negative values may signal distress.

This tracks the rate at which a startup consumes its cash reserve to cover overhead before generating positive cash flow. Series A investors closely monitor gross and net burn rates to calculate runway and assess the efficiency of capital deployment.

Calculated by dividing current cash reserves by the monthly burn rate, runway estimates how many months a startup can operate before running out of money. Investors prioritize a sufficient runway (typically 12-18 months) to ensure the company reaches key milestones post-funding.

DSO measures the average number of days it takes to collect payment after a sale. A high DSO indicates poor cash collection efficiency, which can strain liquidity even if revenue looks strong on paper, raising red flags for investors about cash flow management.

This metric tracks the average time a company takes to pay its suppliers. While a longer DPO improves short-term cash flow, investors look for a balance to ensure suppliers remain healthy and willing to extend credit, indicating stable vendor relationships.

DIO measures how long it takes to turn inventory into sales. For product-based startups, a high DIO suggests sluggish inventory movement and tied-up capital, which negatively impacts liquidity and requires careful management to avoid obsolescence risks.

This cycle combines DSO, DIO, and DPO to show the total time it takes for a company to convert its investments in inventory and other resources into cash flows from sales. A shorter cycle indicates higher liquidity and operational efficiency.

This ratio measures how efficiently a company collects revenue from its customers. High turnover suggests strong collections processes and liquid cash inflows, whereas low turnover may indicate customer payment issues or overly lenient credit policies.

Measuring how quickly a company pays its bills, this ratio helps investors assess payment discipline and supplier trust. Consistent and timely payments can improve credit terms and vendor relationships, indirectly supporting better liquidity conditions.

Originally a banking regulation, this concept is increasingly relevant for startups to ensure they hold enough high-quality liquid assets to survive a significant stress scenario. Investors use this lens to evaluate resilience against unexpected market shocks or funding gaps.

This metric subtracts total liabilities from total current assets to show the net value available for long-term solvency. It provides a clear snapshot of the financial buffer a startup possesses to absorb short-term shocks or fund immediate opportunities.

The percentage of available credit line currently being used indicates reliance on debt for daily operations. High utilization can signal tight liquidity and potential refinancing risks, which investors view as a negative indicator of financial stability.

This ratio divides cash burn by net new annual recurring revenue, showing how much cash is spent to generate each dollar of growth. Investors prefer a low multiple, indicating efficient capital usage and a sustainable path to profitability post-Series A.

For subscription models, this measures the proportion of cash collected in advance for services not yet delivered. A healthy ratio provides a strong liquidity buffer since the cash is already in hand, reducing reliance on external financing for near-term operations.

This assesses the company's value based on tangible assets alone, excluding intangible assets like patents or goodwill. Investors use it to determine the liquidation value and collateral coverage in worst-case scenarios, providing a floor for valuation negotiations.

An aggregate metric evaluating access to various funding sources, including equity, debt, and internal cash flow. Investors look for high flexibility, which allows startups to navigate volatility and seize growth opportunities without being constrained by rigid liquidity constraints.
