A business line of credit is a borrowing limit a business draws on as costs arise and repays as cash arrives, with interest usually charged only on the drawn balance. Crestford Lending, a small-business funding broker in Waterloo, Iowa, explains draws, revolving and non-revolving lines and routes requests to lending partners, which decide and set terms.
| Designed for | Costs that recur but never arrive in the same size twice |
|---|---|
| Interest | Normally accrues only on what you have drawn |
| Reusable | Yes on a revolving line; no on a non-revolving one |
| Watch for | Per-draw charges, upkeep fees and yearly renewals |

Drawing on the line, step by step
A draw is simply taking money out of the line, usually by transfer into the business checking account. If the limit is a round figure and you draw a quarter of it to pay a supplier, you owe that quarter plus interest on it, while the rest stays available. Once you pay the draw back, a revolving line makes that amount available again.
That flexibility is the point. A Cedar Falls retailer who restocks unevenly, or a Waterloo contractor who buys materials before each phase of a job, can borrow exactly when and as much as the cost requires, instead of paying interest on a lump sum sitting idle.
A limit that resets, or one you can only spend once
A revolving line resets as you repay, much like a credit card, and can be used again and again during the draw period. A non-revolving line lets you draw up to the limit, but repaid amounts do not become available again; once the limit has been used, the line is spent. Non-revolving lines sometimes suit a project with several stages, where the money is needed over months rather than all at once.
Ask how long the draw period lasts, whether the line is reviewed or renewed each year, and what happens to the balance if the partner decides not to renew.
Interest on a line: what you actually pay for
Most lines charge interest only on the outstanding balance, calculated daily or monthly. Many carry a variable rate that moves with a benchmark, so the cost of the same balance can change. Some lines add a draw fee per withdrawal, an annual or maintenance fee, or a fee for unused balances. When you compare offers, ask for every charge in writing and estimate the cost at the balance you actually expect to carry, not the full limit.
Covering wages from the line
A line of credit can cover payroll, and for businesses whose receipts swing from week to week it is often a better fit than a lump sum. The caution is the same as with any short money: draws for wages should be repaid from incoming receivables, not rolled forward indefinitely. A balance that never comes down is a sign that the business needs a different fix.
The question comes up most when an owner adds a first employee. Funding a first hire in Black Hawk County compares a line with other ways to carry the first months of wages.
Who uses lines around Black Hawk County, Iowa
Small firms dominate the county's business base. Of Black Hawk County's 3,105 employer establishments in 2023, 1,376 ran with four or fewer employees (U.S. Census Bureau, County Business Patterns 2023), and 8,500 more businesses had no payroll at all in 2024 (Nonemployer Statistics 2024). For small operations, a line often works as a cash buffer that is cheaper to keep idle than a loan.
Sectors with uneven cash timing, such as specialty trades, wholesalers and retailers, appear on the sector pages, and the office ZIP's own mix is on the Black Hawk County picture.
Secured and unsecured lines
Smaller lines are sometimes unsecured and rest on the business's bank history and the owner's credit, often with a personal guarantee. Larger lines are commonly secured by receivables, inventory or a general lien on business assets, recorded by a UCC filing. Either way, partners tend to want to see steady deposits and evidence that past balances were paid down.
Revolving limit or one-time loan
| Line of credit | Term loan | |
|---|---|---|
| Best for | Recurring, unpredictable costs | A single project with a price tag |
| Money received | As you draw | All at once |
| Interest | On the drawn balance | Charged on the whole sum from the first day |
| Payment | Varies with the balance | Fixed schedule |
If the need is one large purchase, a business term loan is usually cleaner. If the gap is a single event with a known end, working capital may be simpler. All six routes are in the comparison, and how a request moves covers what happens after you call.
