Harbor Coffee, our fictional coffee business, reports $341.4 million of current assets and $146 million of current liabilities at FY3-end. More than twice as much on the asset side sounds comfortable. But some of those assets are bags of coffee, and some are invoices customers have not paid.
The balance sheet lists the resources. The liquidity check asks whether they can become cash before the bills arrive.
Three views of the near-term buffer
Liquidity is a company's ability to meet short-term obligations as they fall due. Profit measures what it earns; liquidity asks whether money arrives in time. Solvency concerns longer-term obligations, which debt and leverage examines later.
Use current assets and current liabilities from the same balance-sheet date.
Working capital = current assets − current liabilities. For Harbor, $341.4 million − $146 million = $195.4 million. That difference includes coffee and unpaid invoices; it is not a bank balance.
The current ratio divides the same two totals:
Harbor's $341.4 million ÷ $146 million = about 2.34. Read that as $2.34 of recorded current assets for every $1 of current liabilities.
The quick ratio uses a narrower group of quick assets: cash and cash equivalents, short-term marketable investments available for payment, and net receivables (customer invoices after estimated losses).
This definition excludes inventory and prepayments. Coffee needs a buyer; prepaid rent covers a future cost rather than supplying cash.
Harbor has no separate marketable investments, its cash is unrestricted, and its other current assets are prepayments. Its quick assets are $105.4 million cash + $95 million receivables = $200.4 million.
Divide $200.4 million by $146 million to get about 1.37: $1.37 of quick assets per $1 of current liabilities.
In a real filing, check cash restrictions and collection risk separately: a quick asset still has to deliver cash on time.
What changed at Harbor
The quick test excludes $115 million of inventory and $26 million of prepayments. The remaining $200.4 million still exceeds the $146 million of current liabilities. Both ratios divide by that same liability total.
One year earlier, at FY2-end, Harbor reported $329.4 million of current assets and $144 million of current liabilities. Cash of $105.4 million plus receivables of $90 million gave $195.4 million of quick assets.
Calculated from the two year-end snapshots:
| Measure | FY2 | FY3 | Unit |
|---|---|---|---|
| Working capital | 185.4 | 195.4 | USD m |
| Current ratio | 2.29 | 2.34 | times |
| Quick ratio | 1.36 | 1.37 | times |
Working capital grew $10 million. Receivables rose $5 million, inventory $5 million and prepayments $2 million, while supplier bills rose $2 million. Cash stayed at $105.4 million.
That $10 million increase ties up money in operations. The cash flow lesson will pick up the same change with the opposite sign: a $10 million cash use.
Why less working capital can work
A current ratio below 1 means current liabilities exceed current assets: negative working capital. That alone does not tell you whether a payment has been missed or the business can survive.
Consider a retailer that collects money at the checkout and pays suppliers later. When goods sell before supplier bills fall due, customer cash can fund those payments. Reliable incoming sales can support negative working capital. A business that waits months for customers to pay needs more money to bridge the gap.
Advance-paid subscriptions offer another pattern. Tessel Software, our fictional subscription business, reports $560 million of deferred revenue within its $695 million of FY3 current liabilities. This is service owed to customers who have already paid. The revenue lesson explains why collecting cash and earning revenue happen at different times.
Tessel has positive working capital: $1,430 million of current assets − $695 million = $735 million. An advance-paid business could have negative working capital if it spent the cash on long-lived assets while still owing service. Customers have supplied funding; the service obligation remains.
Cash paid ahead still has a job to do. Software needs staff and servers. Suppliers can demand faster payment, and customers can stop renewing. The favorable timing works only while the business can fund its next obligations.
High and low need a reason
A current ratio of 2 or a quick ratio of 1 is no universal pass mark. Compare similar business models at the same point in their seasonal cycle. A warehouse stocked before the selling season and one emptied afterward tell different stories.
A high current ratio can hide slow-selling goods or slow-paying customers. The quick ratio removes the goods, but it keeps the invoices. Accounting red flags shows how to investigate those balances.
Suppose a business collects $10 of net receivables in full. Cash rises $10; receivables fall $10. Neither ratio changes, even though the money is now available to pay a bill. The quick ratio gives an invoice the same weight as cash.
For Harbor, which payment date would you verify next? Start with when its $95 million of invoices will be collected. Compare bills due before those receipts with the $105.4 million already in cash. A ratio counts dollars; paying bills requires dates. The next lesson's cash flow statement follows how money actually moved.
In short
- Working capital is a dollar difference; current and quick ratios compare assets with current liabilities.
- The quick ratio excludes inventory and prepayments, but still depends on collecting invoices.
- A low ratio calls for a payment calendar, not an automatic failure verdict.
- Negative working capital can reflect customer funding or real payment pressure.
- More working capital can mean more unpaid invoices without another dollar in the bank.
