Short answer: A business may use a line of credit for working capital, but working capital can also come from cash reserves, retained earnings, a term loan, receivables financing or another structure. Compare the written terms—not only the product label.
The terms answer different questions
Working capital generally refers to the resources a business uses to meet short-term obligations and operating needs. In basic accounting, net working capital is current assets minus current liabilities. In financing conversations, “working capital” may also describe the intended use of funds: inventory, payroll, supplier payments, seasonal buildup or a temporary cash-flow gap.
A business line of credit is an access structure. A provider approves a limit, the business may draw subject to the agreement, and some structures replenish available credit as principal is repaid. Draw rules, minimum payments, renewal, fees and whether the line is revolving vary by provider.
The U.S. Small Business Administration lists revolving credit among working-capital uses and separately describes term loans, lines and other SBA-supported structures. That distinction is useful: identify the need first, then evaluate which structure fits it.
Side-by-side comparison
| Question | Working-capital need | Line-of-credit structure |
|---|---|---|
| What is it? | A business purpose or liquidity measure. | A financing arrangement with an approved limit and draw rules. |
| Typical use pattern | Inventory, payroll, suppliers, seasonal expenses or cash-cycle timing. | Recurring or uncertain needs that may arise more than once. |
| How funds arrive | Depends on the source: cash, one-time proceeds, draws or receivables. | Draws are requested under the agreement, subject to availability. |
| Can funds be reused? | Not a feature of the need itself. | Possibly, if the line is revolving and the agreement restores availability after repayment. |
| Cost basis | Depends entirely on the selected source. | May include interest or other financing charges on draws plus draw, maintenance, origination or other fees. |
| Main documents to inspect | Cash-flow forecast and the actual financing offer. | Credit limit, draw conditions, payment schedule, pricing, fees, renewal and default terms. |
When a line may fit a working-capital need
A reusable line can align with needs that repeat or are difficult to size in advance. Examples include a seasonal inventory cycle, a lag between completing work and collecting receivables, or variable purchasing needs. The practical question is whether the expected cash inflow arrives before payments create pressure on the business.
A one-time financing structure may be easier to evaluate when the project amount and timing are known. If a business is purchasing a defined piece of equipment or completing a fixed renovation, it can compare one disbursement and one payment schedule with the projected return from that project.
Neither description determines approval, pricing or suitability. A provider may review cash flow, time in business, credit information, existing obligations, collateral or guarantees and other factors.
Map the financing to the cash cycle
- Name the expense. Separate a recurring operating gap from a one-time investment.
- Date the outflow. Record when suppliers, payroll or project costs must be paid.
- Date the expected inflow. Estimate when customer payments, receivables or seasonal sales will arrive.
- Stress the timing. Test what happens if revenue is lower or arrives later than expected.
- Overlay every payment. Compare payment amount and frequency with the business's actual cash-flow calendar.
The Federal Reserve Banks' 2026 Small Business Credit Survey found that operating expenses and expansion opportunities were leading reasons businesses sought financing. It also reported that many online-lender borrowers experienced higher actual borrowing costs than expected. That makes total-cost and payment-timing review especially important.
Questions to answer from a written offer
- Who is the named provider and who will service the obligation?
- How much will reach the business after any withheld fees or payoffs?
- What is the maximum total repayment or finance charge?
- Are charges based on the approved limit, each draw, the outstanding balance or another measure?
- How frequently are payments due, and can the amount change?
- Does repaid principal become available to draw again?
- What fees apply to origination, draws, inactivity, renewal, late payment or prepayment?
- Can the provider reduce availability, require full repayment or decline renewal?
- Do a personal guarantee, business lien or specific collateral requirements apply?
