Firspring Capital, a small-business funding broker in Sioux City, Iowa, arranges business lines of credit through lending partners. A line is a limit you draw from as costs arise; you pay interest only on the drawn balance, and repayments on a revolving line free the limit again. Partners decide every request and set the limit, rate and terms.
| What it is | A limit you draw from as costs arise |
|---|---|
| Interest | On the drawn balance only |
| Types | Revolving lines refill; non-revolving ones are used once |
| Watch for | Variable rates, draw or maintenance charges, liens |
| Woodbury County specialty trades | 175 employer establishments (CBP 2023) |
Drawing on a line, step by step
Drawing means moving money from the line into your business account, by transfer or by a card or check tied to the line. Interest begins on the drawn dollars and nothing else. If a partner approves a limit and you draw a fifth of it to pay a supplier, interest runs on that fifth; the rest is available but costs nothing in interest while unused, although some lines carry a maintenance or unused-line charge, which the offer must spell out.
Draw periods and repayment periods
Many lines have two phases. During the draw period you can borrow, repay and borrow again, and the minimum payment may cover only interest. When the draw period ends, the line closes to new draws and the remaining balance is repaid over a set repayment period. Other partners skip the two phases and re-review the line once a year. Ask the partner which model applies, how long each phase lasts, and what triggers a review.
Revolving and non-revolving lines
On a revolving line, every dollar you repay becomes available again, like a credit card. A non-revolving line lets you draw up to the limit once, in one or more pieces, but repayments do not restore the limit; when it is used, it is used. Non-revolving lines suit a project with stages, such as a remodel paid in phases. Revolving lines suit costs that recur with no fixed end.
Where the interest on a business line comes from
Interest is normally calculated on the daily outstanding balance and billed monthly. Rates are often variable, tied to a published index plus a margin, so the cost can change while you carry a balance. Look for three things in an offer: the rate and whether it varies, any draw or maintenance charge, and whether the line is secured by a general lien on business assets.
Secured lines take a lien, often a blanket UCC filing over business assets. Unsecured lines skip specific collateral but usually require a personal guarantee.

For a single purchase with a long life, compare business term loans. For one short gap with a clear end, working capital may be simpler. Every option sits on the comparison page.
Who in Woodbury County, IA uses a line
Contractors are the classic example. Woodbury County had 175 specialty trade contractor establishments in 2023, about half of them with fewer than five employees (U.S. Census Bureau, County Business Patterns 2023). Materials for one job are bought before the previous job pays, and a line covers that overlap again and again. Our post on what small Siouxland contractors should line up first goes through it step by step. More county figures are on the Siouxland business picture page, and other sectors are on funding by sector.
What partners review
- Business bank statements showing deposits and average balances.

- Existing debt payments, including any advances being collected.
Lines are usually reviewed again at renewal, so the same records matter after approval too. The full sequence is on how a request works.
