A business line of credit is a revolving limit a business draws against as costs arrive, paying interest only on the drawn balance. Marbleharbor Advances, a small-business funding broker in Franklin, Tennessee, helps Williamson County owners decide whether a line fits their cash cycle and introduces the request to lending partners, which make credit decisions and set rates and terms.
| How it works | Draw up to a set limit, repay, draw again |
|---|---|
| Interest | Accrues only on money actually drawn |
| Draw period | The window in which you may draw; repayment may continue after it |
| Good fit | Recurring costs of varying size, short timing gaps |
| Poor fit | One large purchase that will take years to repay |
| Who decides | The lending partner sets the limit, rate and conditions |
What it means to draw on a line of credit
Drawing means moving money from the line into your business account, by transfer, check or card depending on the lender. Each draw increases the balance; each payment reduces it and, on a revolving line, frees that much of the limit for later use. You do not apply again for each draw. That is the core difference from a loan: the approval covers a limit, and you decide when and how much of it to use.
How business line of credit interest works
Interest accrues on the outstanding balance, usually daily, and is billed monthly. A line that sits untouched normally costs nothing in interest, though some lenders charge a maintenance or draw fee, so ask. If you draw an amount for twenty days and pay it back, you pay roughly twenty days of interest on that amount, not a month's worth on the full limit.
To check a statement by hand: multiply the balance by the annual rate, divide by 365 (or 360, if the contract says so), and multiply by the number of days the balance was outstanding. Add each period together if the balance changed during the month.
Draw period and repayment period
Many lines have a draw period, a set window during which you can borrow. When it ends, the line may renew after a review, or it may convert to a repayment period in which you can no longer draw and the remaining balance is paid down in installments. Some short-term lines treat each draw as its own small installment loan with its own schedule. Ask which structure an offer uses, because it changes how the payments behave.
Four ways a line can be set up
- Revolving: repaid amounts become available again, for as long as the line is open.
- Non-revolving: each draw permanently uses part of the limit, even after repayment.
- Secured: backed by receivables, inventory, equipment or real estate; larger limits are more common.
- Unsecured: no named collateral, but usually a personal guarantee and sometimes a general UCC filing on business assets.
Partners also review the line periodically. A lender can reduce or freeze a line if the business changes, so a line is a convenience rather than a promise of future cash.
Using a line for payroll and other recurring costs
Payroll is a natural use when the timing gap is short and predictable: a pay date that lands before customer payments clear. The line covers the gap, and the incoming deposits pay it down. The pattern to avoid is a balance that never falls, which signals the business is funding losses rather than timing. In that case a working capital loan with a fixed end date, or a hard look at pricing and costs, may serve better.
Choosing between a credit line and a term loan
| Line of credit | Term loan | |
|---|---|---|
| Funds | Drawn as needed | One lump sum |
| Interest | On the drawn balance | On the full outstanding balance from day one |
| Repayment | Flexible within the contract; limit refills | Fixed schedule over the term |
| Suits | Recurring and uneven costs | One-time projects with a known price |
For a build-out or a second location, a term loan generally fits better. The comparison of all six options shows the rest.
Lines of credit for Williamson County, TN businesses
Service businesses with irregular billing are common here. Professional, scientific and technical services had 1,322 employer establishments in Williamson County in 2023, more than any other sector, and 67.6 percent of them had fewer than five employees (U.S. Census Bureau, County Business Patterns 2023). Firms like these often bill in arrears and pay staff on a fixed calendar, which is the gap a line is built for. The sector pages cover contractors, restaurants and practices, and the Franklin, TN page has the wider local picture. How a request moves explains the next step.
