A secured business line of credit gives a Marion, IN contractor a limit backed by collateral, often receivables or equipment. The contractor draws to buy materials, pays the balance down as clients pay, and pays interest only on the days money is out.
This article from Baymark Commercial Capital in Marion, Indiana explains how secured, operating and revolving credit lines work for a contractor, with an invented six-month materials cycle and interest figured day by day.
How Does a Commercial Line of Credit Work? A Grant County, IN Contracting Business Example
The direct answer: a commercial line of credit sets a limit the contractor can draw on, pay down and draw again, and a secured line names collateral behind that limit. For a contracting business, the collateral is often its receivables, with the limit tied to a share of what clients owe; sometimes it is equipment or a general lien on business assets. Limits, draws and yearly renewals get their own treatment on the business line of credit page.
Illustration only, invented figures: a contractor with $40,000 of eligible receivables and a lender advancing 80% has a borrowing base of $32,000 (our arithmetic). As invoices are paid and new ones are billed, the base moves with them.
How Does an Operating Line of Credit Work Between Draws on a Job?
An operating line is the name lenders often give a line meant for the day-to-day cycle of a business: buy materials, do the work, bill, get paid, pay down. For a contractor, one cycle runs from the supplier invoice to the owner's draw payment. The line carries the gap, and its balance should come back down when the draw is paid.
A line that never comes down is a sign the business needs longer money: a term loan for the equipment or the expansion that is really being paid for, so the line can go back to carrying the job cycle. Many lenders require a clean-up period each year when the balance drops to zero or near it; ask whether one applies.
How Does a Business Revolving Line of Credit Work When Bonding Costs Come Due?
Bonding costs arrive at the start of a job: the performance and payment bond premium is due when the contract is signed. A revolving line can carry the premium until the first draw. A surety writing the bond will itself read the contractor's working capital and the line available, so the line can help the bond as well as pay for it.
Larger, longer bonded jobs may need more than a line. The working capital loans page covers a single dated gap, and the construction business loans page covers retainage and draw delays.
How Does a Secured Business Line of Credit Work When a Client Pays Late?
When a client pays late, the balance stays up longer and the interest keeps running. A secured line also has a second effect: if the late invoice ages past the lender's cutoff, often 90 days, it drops out of the borrowing base, and the available limit shrinks just when the contractor needs it.
- Track each invoice's age against the lender's eligibility cutoff.
- Bill promptly and follow up early on slow payers.
- Ask the lender how concentration limits work if one client owes most of the receivables.
- Keep long purchases off the line; machines belong on equipment financing.
What Grant County, IN Figures Show About Contractors
Contractors are a small-firm trade in Grant County, IN: 60 of the 100 construction employers in the county had fewer than five employees in 2023, and the group as a whole paid $51.4 million to 826 workers (County Business Patterns). Specialty trade contractors made up 60 of the 100 and building construction firms 33. On top of those, 345 one-person or family construction outfits with no payroll show up in the 2024 Nonemployer Statistics, counted on their own.
ZIP 46953 held 32 construction employers in 2023 (ZIP Code Business Patterns). Sector-by-sector employer counts for Grant County, IN appear on the Marion, IN page.
For a lender setting a contractor line, those small-firm shares matter less than the contractor's own records: work in progress, backlog, the clients behind the receivables and how long each takes to pay. A schedule of open jobs, with contract value, billed to date and percent complete, answers most of the first questions.
An Invented Six-Month Materials Cycle on a Secured Line, Interest Day by Day
Illustration only, invented figures: a contractor uses a secured line at an annual rate of 11.25%, with interest figured daily on the balance, over 180 days:
| Day | Movement | Balance after |
|---|---|---|
| Day 1 | Draw $18,000 | $18,000 |
| Day 30 | Draw $12,000 | $30,000 |
| Day 45 | Paydown $15,000 | $15,000 |
| Day 75 | Draw $8,000 | $23,000 |
| Day 120 | Paydown $15,000 | $8,000 |
| Day 150 | Paydown $8,000 | $0 |
Interest over the 180 days comes to about $831.27 (our arithmetic), charged only on the balance each day. The same materials bought with a six-month term loan for the peak amount would carry interest on the whole $30,000 from the first day, including the weeks the money was not needed. Real lines may add fees and figure interest monthly; ask for an example on your own job calendar.
