Best working capital loans for contractors in 2026
The best working capital financing for a contractor is a line of credit, which covers materials and labor between progress payments and is repaid as draws arrive. A working capital advance can fund mobilization on a job starting immediately, at a much higher cost. A term loan suits permanent growth in the amount of work you carry.

- Best overall
- Business line of credit
- Best for stepping up to bigger jobs
- Online term loan
- Best for mobilization this week
- Working capital advance
- Best for contractors invoicing commercial clients
- Invoice factoring
The 4 best options, ranked
1. Business line of credit Best overall
Job costs come first and payment later on nearly every project. A line is built for that pattern and costs nothing between jobs.
Watch for: Some lenders add draw or maintenance fees, and a limit can be cut at renewal. Business line of credit guide →
2. Online term loan Best for stepping up to bigger jobs
Larger jobs permanently raise the working capital you need. A term loan adds that capital with a fixed payment.
Watch for: A longer term lowers the payment but raises the total interest you pay. Term loan guide →
3. Working capital advance Best for mobilization this week
When a contract requires materials on site before a bank could act, an advance bridges to the first draw. Price it into the job.
Watch for: The most expensive option on this list, and daily or weekly remittance strains thin margins. Working capital guide →
4. Invoice factoring Best for contractors invoicing commercial clients
Service and maintenance contractors with simple invoices to commercial customers can factor them. Progress-billed construction is harder to factor.
Watch for: Your customers pay the factor directly, and with recourse factoring you still carry non-payment risk. Invoice factoring guide →
Side-by-side comparison
| Option | Verdict | Cost basis | Funding speed | Qualifies on |
|---|---|---|---|---|
| Business line of credit | Best overall | Representative 8%–30% APR, charged only on what you draw | Often days | Revenue, time in business, and credit |
| Online term loan | Best for stepping up to bigger jobs | Representative 8%–30% APR, fixed payments over 6 to 60 months | Days | Revenue, time in business, and credit |
| Working capital advance | Best for mobilization this week | Often a factor rate rather than an APR; compare total payback | As fast as 24 to 48 hours | Recent revenue and cash flow more than credit score |
| Invoice factoring | Best for contractors invoicing commercial clients | A factoring fee on invoice value, not an APR | Days | Your customers' creditworthiness more than your own |
What it costs
A line of credit charges interest only on the balance you have drawn. This is the monthly interest on a carried draw, before any principal is repaid:
| Carried draw | At 8% APR | At 19% APR | At 30% APR |
|---|---|---|---|
| $25,000 | $167 | $396 | $625 |
| $75,000 | $500 | $1,188 | $1,875 |
| $200,000 | $1,333 | $3,167 | $5,000 |
Interest-only illustration across the representative band. Draw fees and repayment schedules vary by lender. WithFunded calculation.
Fast working capital is usually priced as a factor rate: a multiplier on the amount advanced. The total you repay is fixed up front, whatever the payment schedule.
| Advance | Payback at 1.20 | Payback at 1.25 | Payback at 1.30 |
|---|---|---|---|
| $25,000 | $30,000 | $31,250 | $32,500 |
| $60,000 | $72,000 | $75,000 | $78,000 |
| $120,000 | $144,000 | $150,000 | $156,000 |
A $60,000 advance at a 1.25 factor means $75,000 in total payback, a $15,000 cost of capital. Compare offers by total payback and by how fast you must repay, not by a headline percentage. Illustrative factor rates. Actual factors are set by the lender. WithFunded calculation.
What lenders look at
- Signed contracts and the schedule of values.
- Receivables aging, with retainage shown separately.
- Margins on completed jobs.
Mistakes to avoid
- A daily-payment advance on a job that pays monthly. The remittance will outrun your draws.
- Financing a job whose margin does not cover the cost of the money.
Frequently asked questions
- How do contractors get working capital?

- Only for a short bridge on a profitable job. Daily or weekly remittance fits poorly with monthly progress payments.
- What does a $60,000 advance cost?
- At an illustrative 1.25 factor, $75,000 in total payback.

Landon and Austin were greatLandon and Austin were great. Knowledgable and explained everything in a way that made it all really easy to understand. I avoid these call like the plague but these two were a joy to work with.
Highly recommendedHighly recommended! I worked with Corey, and he was awesome. He found an option after I received multiple rejections that no other company had presented to me. It was within my budget and my timeline. I'm so thankful!
BTC has become my go to for working…BTC has become my go to for working capital. Recently, my company was in a bind and needed funds. The BTC team, headed by Drew, took a problem solving approach and helped to overcome an initial denial, resulting in a better facility than the one I was turned down for. Thanks BTC! Thanks Drew!

How we ranked these options
This guide ranks types of financing, not individual lenders. Each option is ordered by how well it fits the need described on this page, judged on four things in this order: whether the structure matches how the money will be used and repaid, total cost, funding speed, and how hard it is to qualify. Cost figures are WithFunded calculations from published rate inputs as of November 2026: the bank prime loan rate from the Federal Reserve, the SBA maximum-rate schedule, and Federal Reserve survey data. The method follows our 2026 SMB Financing Cost Report, whose own figures use June 2026 rates.
WithFunded is a financing marketplace, not a lender. Our 2-minute form suggests a product type from the families we cover, and a funding partner reviews the request. Not every structure named in this guide is available through WithFunded: options such as SBA microloans, USDA farm loans, bank loans, and seller financing are ones you would pursue directly with the provider. They are listed because leaving out a good fit would make the ranking less useful.
