Working Capital Financing: How Businesses Use Funding To Manage Cash Flow

October 13, 2026

Working capital financing is a type of business funding that helps companies pay for daily operating expenses like payroll, inventory, rent, and supplier invoices. It can be used to cover expenses when cash is needed, but customer revenue hasn't come in yet. The best type of working capital financing depends on how much cash is needed, for how long, and if the business can afford the cost of funding on top of other expenses.

A business can be profitable but still run out of cash. Customers may delay payments; inventory may need to be ordered before a peak season, or multiple expenses may come due in the same week.

56% of businesses that applied for financing did so to meet operating expenses, according to the 2026 Report on Employer Firms (2025 Small Business Credit Survey) by the Federal Reserve Banks. This statistic demonstrates how common it is for companies to apply for funding to support day-to-day operations.

Definition

Working capital financing is funding that a business uses to support short-term operating needs. It is a type of financing, rather than a specific product. A company may utilize a line of credit, term financing, revenue-based financing, or invoice factoring to fund working capital needs. For instance, a cleaning company may have to pay employees on a weekly basis, while commercial clients pay invoices on a monthly basis. Working capital funding would help bridge the gap, as long as the company can afford the financing costs when customers pay invoices.

Working Capital vs Cash Flow

Working capital is the difference between a company's current assets and current liabilities at a point in time. Cash flow is the amount of money that enters and leaves a company over a period of time.

A company may have positive working capital because customers owe them money or because they have valuable inventory. That doesn't mean they have enough cash on hand to pay next week's payroll.

Financing may be needed to cover a short-term gap. If expenses are consistently more than the amount of cash a company generates, then the owner will need to look at prices, costs, or operations.

Working Capital Formula

The working capital formula is:

Working Capital = Current Assets – Current Liabilities

Bank of America uses the same formula for working capital to differentiate between net working capital and the working capital ratio.

Current assets are cash, accounts receivable, and inventory that a company plans to use up or convert to cash within one year or the normal operating cycle. Current liabilities are debts that are due within a year, including supplier invoices, accrued expenses, and the current portion of debt.

A Simple Working Capital Example

Take this fictitious company for example:

This company has positive working capital of $25,000, but only $15,000 of assets are cash. Some of its invoices may not be due for a while, and its inventory will need some time to sell.

The financial ratios section states that the current ratio is the ratio of current assets to current liabilities. This ratio is used by the U.S. Census Bureau's Quarterly Financial Report to determine the company's ability to satisfy its current liabilities from its current assets.

The ratio in this example is about 1.63.

Neither working capital nor the current ratio can substitute for a cash forecast. Furthermore, short-term borrowing increases both cash and current liabilities by the same amount, thereby improving a company's liquidity without changing its net working capital.

Business Uses

The owner can best use working capital financing when he or she knows what the expense is, what they expect to receive in cash, and when between the two events the expense will occur.

Payroll and Other Normal Operating Expenses

Payroll, rent, utility bills and supplier bills may be due before your customers pay. You may be able to obtain financing to cover the short-term need, provided the timing of the payments matches your company's expectations.

If you routinely need financing for these types of expenses, consider whether you are having a continuing problem with late payments, low margins or increasing costs.

Inventories Prior to a Peak Season

A retailer may need to purchase inventories prior to a peak season when sales are high. You may be able to obtain financing for the inventories to free up cash to cover other expenses.

Before ordering large amounts of inventory, review prior sales, delivery times and storage costs as well as the risk that products may not sell. Remember, you will still owe the obligation for your financing even if sales are slower than anticipated.

Materials and Labor for New Contract Work

Growth means needing cash before you can receive cash. A contractor may have to purchase materials and hire additional labor before receiving a payment for new contract work.

Match your budget to the payment schedule of the project, allowing for delays. A bigger contract is only beneficial if you can complete it and still earn a profit after all expenses, including the cost of financing, have been paid.

Unexpected Operating Expenses

An emergency repair or replacement order may upset all plans for a viable cash flow. You may be able to obtain financing to keep the business running, provided the amount of the financing reflects the expense, and your payment terms are reasonable.

If you are considering purchasing major equipment with a long, useful life, consider equipment financing instead of using short-term operating funds.

Cash Flow Issues

Cash flow issues can be tackled by different financing options. Consider the overall cost of the agreement, how often you must pay and what your liabilities are, not just how quickly you can pay.

Match the Structure to the Gap

A line of credit for business can be drawn upon up to the approved amount, subject to terms. It may be right for expenses that are variable for that come at different times. Term financing involves a disbursement of funds upfront and may be right for a well-defined expense. Revenue-based financing is tied to your business's revenue. Make sure that your collections depend on your sales, and don't assume that adjustments will be made automatically. Invoice factoring usually entails the sale of invoices. Make sure who will be contacting your customers, and what will happen if an invoice is unpaid.

Consider SBA Programs, Where Right

Working capital is listed as an allowable use of proceeds under the SBA's 7(a) program. Microloans from the SBA may be used for working capital, inventory, and supplies, and microloans may not be used to pay pre-existing debts or to acquire real estate.

Qualifications and specific terms will vary depending on the program and the participating provider.

Use Funding to Improve Cash Flow

Funding should be paired with a strategy for collecting money, managing expenses, and forecasting shortfalls.

Forecast When Money Will Come In

Prepare a weekly forecast of your opening cash balance, customer receipts, and payments. Use realistic collection dates for invoices, instead of assuming that customers will pay immediately. Include taxes, payments on existing financing arrangements, and any contemplated new collections. Run scenarios where major customer fails to pay on time, or sales fall short of expectations.

Make Customer Payments Easier to Collect

Invoice customers promptly, with clear payment terms. Consider deposits or progress billing, where appropriate, so that you don't have to complete a major project before getting paid. Follow up on late invoices and resolve disputes quickly. Reducing the time between completing a job and getting paid can make less outside funding necessary.

Review Inventory and Supplier Terms

Slow-moving inventory ties up cash that could be better spent elsewhere. Evaluate purchasing decisions against sales, and don't order large quantities for a volume discount. Inquire about payment terms that align with your collections. Negotiate changes before the bill is due, rather than simply pushing back on the due date.

Measure Whether Funding Solves the Problem

Compare results to your forecast. Did you receive customer receipts when you expected them? Did financing costs leave enough cash behind to make regular payments? If the shortfall recurs, go back to the drawing board before accepting more funding. An accountant can help you determine whether you're dealing with a timing issue or a business model that requires adjustment.
