A business line of credit gives a business a borrowing limit it can draw on, repay and reuse, with interest charged only on the drawn balance. Quarrystone Loans, a small-business funding broker in Sumter, South Carolina, explains draws, renewals and collateral to Sumter County owners and introduces requests to lending partners, who decide and set rates and terms.

A draw, explained
A draw is a transfer from the line into your business account. If the partner approves a limit and you draw a quarter of it to cover a supplier invoice, you owe interest on that quarter only. Each repayment frees that room up again. Most lines can be drawn online or by request, and some come with a card or checks.
Ask how a draw is made, whether each draw carries a fee, and how quickly the money lands in your account. Those mechanics shape how useful the line is in practice.
Revolving versus one-pass credit lines
A revolving line refills as you repay: borrow, pay down, borrow again, up to the limit, for as long as the line is open. A non-revolving line lets you draw up to the limit during a draw period, but repayments do not restore the available amount. Non-revolving lines behave more like a term loan taken in pieces, and they suit a project paid in stages more than an ongoing need.
Where the interest comes from on a credit line
Interest builds on whatever is outstanding, normally day by day, with a monthly bill. Many lines charge a variable rate tied to an index, so the cost can move during the life of the line. Some lines also carry an annual fee, a maintenance fee or an unused-line fee, and some require the balance to be paid to zero for a period each year. Read every fee in the agreement, not just the rate, and ask how often the partner reviews the line and on what basis it may reduce or close it.
Payroll and other recurring uses
Will a partner let the line cover wages? Usually, yes, and covering wages while receivables are outstanding is one of the most common reasons owners keep a line open. The caution is using a line to cover a gap that never closes: if the balance only climbs, the business has a revenue problem that more borrowing will not fix.
Fewer than five people worked at 831 of Sumter County's 1,833 employer establishments in 2023 (U.S. Census Bureau, County Business Patterns 2023). For a business that size, a single slow month can stretch payroll, and a modest line held in reserve can be steadier than repeated short-term borrowing. For stores that buy stock ahead of sales, our post on financing store inventory compares a line with inventory financing and supplier terms.
Pledging collateral against a line, or not
A secured line is backed by collateral, often receivables or inventory, sometimes a blanket lien on business assets. An unsecured line relies on credit history and cash flow and usually comes with a personal guarantee. A secured line may offer a higher limit or a lower price; an unsecured line keeps assets unpledged. A partner that bases the limit on receivables or stock may cap draws at a share of their value and ask for regular reports.
Points a partner checks on a line request
- Bank statements showing deposits and average balances
- Years in operation and the direction of sales
- Existing debts and the payments on them
- Receivables aging, if the line is secured by receivables
- The owner's credit history and willingness to guarantee
Criteria vary from partner to partner. Our Sumter, SC page shows how local employers break down by size and sector, and the industry overview shows where a line fits different cash cycles.
When a term loan beats a credit line, and vice versa
A term loan suits a one-time cost with a known price; a line suits recurring costs of unknown size. If the cash gap closes on a predictable date, working capital financing may be simpler. Term loans and every other option are laid out in the comparison, and the four steps explain what happens after you call.
