A business line of credit fits contractors as a revolving buffer for the gap between when you spend on a job and when you get paid — you draw to cover payroll, materials, and mobilization, then pay it back down as progress payments, retainage, and final invoices land. Because it's revolving, you only carry (and pay for) what you're actually using, which maps almost perfectly to the stop-start cash flow of construction and the trades. It works best when your books are clean, your receivables are predictable, and you have time to underwrite. It fits poorly when you need money this week, your FICO is under bank thresholds, or your deposits are strong but your paperwork isn't — and that's the exact spot where a revenue-based advance tends to beat a line of credit on speed and approval odds.
Key takeaways
- A business line of credit fits contractors as a revolving bridge for the gap between spending on a job and getting paid — you draw only what a job needs and pay down as progress payments and retainage land.
- It works best with clean books, predictable receivables, credit that clears bank thresholds, and time to underwrite; it fits poorly when money is needed in days or credit is thin.
- When a bank line is out of reach, a revenue-based advance underwrites on bank deposits and revenue rather than credit score — commonly workable at FICO 500+.
- Revenue-based advances typically start around $10,000 and can fund in 24-48 hours, versus days to weeks for a line.
- A line generally offers a lower cost of capital when you qualify; a revenue-based advance trades higher cost for speed and easier approval.
- Best uses are short-cycle and self-liquidating — payroll between draws, materials, retainage bridges — not trucks, equipment, or chronic monthly shortfalls.
- No funding product is ever guaranteed; approval depends on your bank activity, credit, and paperwork.
Why a line of credit maps to how contractors actually get paid
Construction cash flow is not smooth, and no amount of good management makes it smooth. You mobilize a crew, buy materials, and start burning payroll on day one. The customer pays on a draw schedule, net-30 or net-60 terms, or worse — and 5% to 10% of the contract sits as retainage until the job closes out and the punch list clears. That structure builds a permanent hole between cash out and cash in.
A revolving line of credit is designed for exactly that shape. You get an approved limit — say $75,000 — and you draw only what a specific job needs, when it needs it. When the progress payment hits, you sweep it back against the balance and your available credit refills. You pay interest on the drawn portion, not the full limit, so a line you barely touch in a slow month costs you little. For a contractor juggling three jobs on three different payment clocks, that flexibility is the whole point.
The mental model that works: treat the line as a bridge, never as a term loan. It should fund a receivable you can already see coming, then get paid down when that receivable arrives. A line that stays maxed for months isn't bridging a gap — it's masking a margin or collections problem, and that's a different conversation.
What contractors actually use a line for
The strongest uses are short-cycle and self-liquidating — the draw funds something that produces cash within weeks, and that cash repays the draw. The weakest uses are long-lived assets or plugging structural losses, which belong on equipment financing or need an operational fix, not a revolver.
- Payroll between draws — you can't tell a framing crew to wait for the GC's net-45. The line covers the weeks in between.
- Materials and mobilization — lumber, concrete, fixtures, and permits often have to be paid before the first progress payment.
- Bridging retainage — that 5%-10% held back can be the entire margin on a job; a line lets you keep working while it sits.
- Taking a second or third job — winning two bids at once is a good problem that still requires cash to staff and supply both.
- Early-pay or volume discounts on supplies — if a supplier gives a discount for paying in 10 days, a cheap draw can more than pay for itself.
Uses to avoid on a line: buying trucks or heavy equipment (finance those and match the term to the asset's life), covering a chronic shortfall every month, or funding an owner draw. If the line never gets paid back down, it has quietly become expensive long-term debt.
Realistic example: how a draw plays out on a single job
These figures are illustrative — for example only — to show the rhythm, not a quote. Notice the balance rises as costs go out and falls as payments come in; that sawtooth is a healthy line at work.
| Week | Job event | Cash move | Line balance (example) |
|---|---|---|---|
| 1 | Mobilize crew, buy materials | Draw for payroll + materials | $42,000 drawn |
| 2 | Payroll run #1 | Additional draw | $55,000 drawn |
| 4 | First progress payment clears | Sweep against balance | $18,000 drawn |
| 6 | Payroll + second material order | Draw back up | $38,000 drawn |
| 9 | Substantial completion payment | Sweep against balance | $6,000 drawn |
| 14 | Retainage released at closeout | Pay to zero | $0 — full limit available again |
The contractor here never carried the full limit and paid interest only on the drawn balance over roughly 14 weeks. The line did its job: it moved the cash forward in time so the crew got paid on schedule, and every dollar came back as the job's own receivables landed.
Decision framework: when a line of credit fits — and when to skip it
A line of credit is a great tool for a specific profile. Be honest about which side of this you're on, because forcing the wrong tool costs you either an approval you'll never get or an expense you didn't need.
A line of credit works best when:
- Your books are clean and current — accurate P&L, aged receivables, filed tax returns.
- Your receivables are predictable and your customers reliably pay (GCs and repeat clients beat one-off cash jobs).
- Your personal and business credit clear bank or fintech thresholds.
- You have time — days to a couple of weeks — to underwrite before you need the money.
- Your need is recurring and short-cycle, so revolving access is worth more than a lump sum.
Avoid a line (or look elsewhere) when:
- You need funds in 24-72 hours to make payroll or lock a material price.
- Your credit is below bank cutoffs but your deposits are strong and consistent.
- Your bookkeeping isn't lender-ready and you can't produce clean statements on demand.
- You want to fund a truck, excavator, or other long-lived asset — that's an equipment-finance job.
- You'd use it to cover a recurring monthly loss rather than a timing gap.
When a revenue-based advance fits better than a line
Plenty of profitable, busy contractors can't get a traditional line — not because the business is weak, but because the paperwork, credit score, or timeline doesn't fit how banks underwrite. If your bank deposits show real, steady revenue but your FICO is in the 500s or your books aren't polished, a revenue-based advance from an MCA-style marketplace is often the realistic path to cash.
The core difference is what gets underwritten. A line of credit is approved primarily on credit and financials. A revenue-based advance is approved primarily on bank deposits and revenue — the lender looks at the cash actually flowing through your account, not just your score. That changes the math on who qualifies:
- Approval basis: deposits and consistent revenue over credit history.
- Credit: FICO 500+ is commonly workable.
- Amount: typically starting around $10,000 and scaling with monthly volume.
- Speed: approvals and funding often in 24-48 hours.
- Repayment: a fixed factor-based payback drawn as a small, regular remittance from revenue — built to move with cash flow, not a revolving balance you manage draw by draw.
This is not a cheaper product than a bank line, and it should never be pitched as one. It's a faster and more accessible one. The honest framing: if you qualify for a line and can wait, the line is usually the better cost of capital. If you don't qualify, or the money has to be in the account before the week is out, a revenue-based advance is what actually gets the crew paid. Nothing in either product is ever guaranteed — approval depends on your file.
Line of credit vs. revenue-based advance: a straight head-to-head
| Factor | Business line of credit | Revenue-based advance (MCA marketplace) |
|---|---|---|
| Primary approval basis | Credit score + financial statements | Bank deposits + revenue |
| Typical credit floor | Higher — bank/fintech thresholds | FICO 500+ commonly workable |
| Speed to funding | Days to a couple of weeks | Often 24-48 hours |
| Structure | Revolving — draw and repay repeatedly | Lump sum with fixed factor-based payback |
| Cost of capital | Generally lower when you qualify | Higher — priced for speed and access |
| Paperwork lift | Heavier — clean books required | Lighter — recent bank statements |
| Best-fit contractor | Clean file, predictable receivables, can wait | Strong deposits, thin credit or urgent timing |
Choose a line of credit if your books are lender-ready, your credit clears thresholds, and you have time — you'll get a lower cost of capital and reusable, flexible access. Choose a revenue-based advance if your deposits are strong but your credit or paperwork won't clear a bank, or payroll and material deadlines won't wait for underwriting. Many contractors end up using both over time: the advance to move fast today, the line once the books and score are strong enough to earn it.
How to get approved faster — for either product
Whichever route fits, the same housekeeping shortens the timeline and improves your odds. Underwriters are reading for one thing: can this business support the payment out of its own cash flow?
- Keep business banking clean. Run revenue through one business account. Consistent, identifiable deposits are the single strongest signal for revenue-based approval and speed up any lender.
- Avoid negative days and excessive NSFs. Frequent overdrafts read as cash-flow stress and are the most common reason a strong-revenue file gets declined or reduced.
- Have statements ready. The last three to six months of business bank statements will cover most revenue-based applications; add current P&L and aged receivables for a line.
- Know your real monthly revenue. Offer amounts scale off deposits, so a lender who can see steady volume can size and price faster.
- Don't stack blindly. Taking multiple advances at once ("stacking") shows up in your bank activity and can sink your next approval. Fund the gap you can see, not more.

Frequently asked questions
Can a contractor get a business line of credit with bad credit?
A traditional line of credit is underwritten heavily on credit score and financials, so sub-bank-threshold FICO usually makes it hard. If your credit is thin but your bank deposits show steady revenue, a revenue-based advance is the more realistic path — it's commonly workable at FICO 500+ because it underwrites on deposits and revenue rather than score. Nothing is guaranteed either way; it depends on your file.
How much can a contractor borrow on a line of credit?
Limits vary widely by lender and by the strength of your books and receivables — a small trades business might see a modest revolving limit, a larger contractor much more. For the faster revenue-based alternative, amounts typically start around $10,000 and scale with your monthly deposit volume, so stronger, more consistent revenue supports a larger offer.
Is a line of credit or a merchant cash advance better for a construction business?
It depends on your file and your timeline. If your books are clean, your credit clears thresholds, and you can wait days to a couple of weeks, a line of credit usually gives a lower cost of capital and flexible, reusable access. If your deposits are strong but your credit or paperwork won't clear a bank, or you need cash in 24-48 hours, a revenue-based advance is what actually gets the job funded.
How fast can a contractor get funded?
A line of credit generally takes days to a couple of weeks because of the underwriting and documentation involved. A revenue-based advance from an MCA-style marketplace often approves and funds in 24-48 hours, since it relies mainly on recent bank statements. Speed is one of the main reasons contractors on tight payroll deadlines choose the advance.
What can I use a contractor line of credit for?
Best uses are short-cycle and self-liquidating: payroll between draws, materials and mobilization, bridging retainage, and staffing a second job you just won. Avoid using it for long-lived assets like trucks or heavy equipment — finance those separately and match the term to the asset — and avoid using it to cover a recurring monthly loss, which signals a margin or collections problem rather than a timing gap.
Does retainage affect how I should use financing?
Yes. Retainage — the 5% to 10% a customer holds back until closeout — can represent the entire margin on a job and often sits for weeks after the work is done. A revolving line lets you keep working and paying crews while that money is held, then pays down when retainage is released. Just plan for the release date; if closeouts drag, the drawn balance carries longer than expected.
What documents do I need to apply?
For a revenue-based advance, the last three to six months of business bank statements will cover most applications, plus a simple application and basic business details. For a line of credit, expect a heavier lift: current profit-and-loss, aged receivables, and often filed tax returns. Keeping revenue in one clean business account with few overdrafts speeds up either process.
Will taking an advance hurt my ability to get a bank line later?
Not inherently — plenty of contractors use a revenue-based advance to move fast today and graduate to a bank line once their books and credit are strong enough. What does hurt you is stacking multiple advances at once, which shows up in your bank activity and can lower your odds on the next approval. Fund the gap you can actually see, keep the account clean, and build toward the cheaper product over time.
