Best business loans for government contractors in 2026
The best financing for government contractors is invoice factoring or a contract-based line of credit, because agencies pay reliably but slowly and work must be staffed before the first invoice. Government receivables are considered very safe, which makes them easy to finance. SBA CAPLines include a contract line for costs tied to a specific award.

The 4 best options, ranked
1. Invoice factoring Best for waiting on agency payments
A government agency is about as creditworthy as a customer gets, so factors advance against these invoices readily, even for a young contractor.
Watch for: Your customers pay the factor directly, and with recourse factoring you still carry non-payment risk. Invoice factoring guide →
2. SBA CAPLines (revolving line) Best for mobilizing on a new award
The SBA Contract CAPLine finances labor and materials for a specific contract and is repaid from that contract's payments.
Watch for: Draws are tied to the season, contract, or receivables the line was approved for. SBA loan guide →
3. Asset-based line of credit Best for established contractors
A contractor with steady federal receivables can borrow against them on a revolving basis, at lower cost than factoring.
Watch for: Expect regular reporting on receivables and inventory, and a limit that moves with them. Business line of credit guide →
4. Business line of credit Best for overhead and bid costs
Proposal writing, compliance, and overhead continue between awards. A conventional line covers costs no contract will reimburse.
Watch for: Some lenders add draw or maintenance fees, and a limit can be cut at renewal. Business line of credit guide →
Side-by-side comparison
| Option | Verdict | Cost basis | Funding speed | Qualifies on |
|---|---|---|---|---|
| Invoice factoring | Best for waiting on agency payments | A factoring fee on invoice value, not an APR | Days | Your customers' creditworthiness more than your own |
| SBA CAPLines (revolving line) | Best for mobilizing on a new award | SBA-capped rates on a revolving line of up to $5 million | Weeks to months | A documented seasonal cycle or specific contracts to borrow against |
| Asset-based line of credit | Best for established contractors | Interest on what you draw; the limit follows a borrowing base of receivables and inventory | Weeks to set up | The quality of your receivables and inventory |
| Business line of credit | Best for overhead and bid costs | Representative 8%–30% APR, charged only on what you draw | Often days | Revenue, time in business, and credit |
What it costs
Factoring is priced as a fee on the invoice, not an APR. You get an advance up front, then the balance minus the fee once your customer pays. At an illustrative 85% advance and 3% fee:
| Invoice value | Advance up front | Factoring fee | You receive in total |
|---|---|---|---|
| $25,000 | $21,250 | $750 | $24,250 |
| $100,000 | $85,000 | $3,000 | $97,000 |
| $300,000 | $255,000 | $9,000 | $291,000 |
Illustrative advance rate and fee. Actual terms depend on your invoice volume, your customers, and how long they take to pay. WithFunded calculation.
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 |
|---|---|---|---|
| $50,000 | $333 | $792 | $1,250 |
| $150,000 | $1,000 | $2,375 | $3,750 |
| $300,000 | $2,000 | $4,750 | $7,500 |

What lenders look at
- The contract itself: agency, term, payment terms, and whether you are prime or a subcontractor.
- Past performance on similar contracts.
- Whether payments can be legally assigned to a lender, which federal contracts allow under specific rules.
Mistakes to avoid
- Bidding a contract you cannot afford to start. Line up financing before the award.
- Assuming a subcontract is as financeable as a prime contract. Your customer is then the prime, not the agency.
Frequently asked questions
- How do small government contractors fund a new contract?
- With invoice factoring once work is billed, and a line of credit or SBA Contract CAPLine for the startup costs before the first invoice.
- Can I factor government invoices?
- Yes. Federal receivables can be assigned to a financing institution under the Assignment of Claims Act, and many factors specialize in them.
- What does factoring a government invoice cost?
- At an illustrative 3% fee, a $100,000 invoice costs $3,000 and pays out $97,000 in total. Fees depend on how long the agency takes to pay.

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.
