Our verdict
A fintech lender offering fast, flexible working capital for small businesses with a lower credit bar, but high costs.
Fundbox offers a revolving business line of credit up to $250,000 with same-day approval decisions and next-business-day funding. It's a strong option for newer or fair-credit businesses that can't meet bank requirements. The tradeoff is cost: Weekly fees translate to effective APRs that can exceed 35%, making it pricier than bank alternatives or competitors like Bluevine.
Best for: Small businesses with fair credit needing fast, short-term working capital.

-
Accepts 600 minimum credit score

Weekly fees translate to high effective APRs
Is Fundbox legit?
Yes. Founded in 2013 and headquartered in San Francisco, Fundbox has served over 500,000 small businesses and deployed more than $3 billion in working capital. Its loans are funded through First Electric Bank, a Utah-chartered industrial bank and FDIC member.
Fundbox holds an A+ rating with the Better Business Bureau (BBB) and has been BBB-accredited since 2014. It uses encryption technology and maintains an extensive help center covering privacy, security and loan servicing. No major lawsuits or regulatory actions appear in recent public records.
What makes Fundbox shine
- Fast decisions and funding. Fundbox’s AI-powered application can deliver a credit decision in as little as three minutes, with funds typically available the next business day — useful when cash flow gaps are urgent.
- Low eligibility bar. A minimum 600 credit score and just three months in business (with a business checking account) make Fundbox accessible to newer or fair-credit borrowers who most traditional lenders would turn away.
- No hidden fees. There are no application, origination, draw or prepayment penalties. You see your full fee total before drawing funds, and paying early waives remaining fees.
- Builds business credit. Fundbox reports account activity to the Small Business Financial Exchange (SBFE), which shares data with major business credit bureaus — a meaningful benefit for businesses working to establish credit.
- Dedicated mobile app. Unlike most alternative lenders, Fundbox offers a mobile app on iOS and Android, letting borrowers manage draws and repayments on the go.
Where Fundbox falls short
- High effective cost. Fundbox charges weekly fees rather than interest, which makes direct APR comparisons difficult. When converted, effective APRs can reach 35% or significantly higher — well above what you’d pay with a bank line of credit or Bluevine, which starts closer to 6% APR.
- Credit limit tops at $250,000. Businesses with larger or ongoing capital needs may outgrow Fundbox quickly. Competitors like OnDeck offer higher limits.
- Short repayment terms only. With a maximum term of 24 weeks and weekly automatic payments, Fundbox can strain cash flow for businesses that need a longer repayment runway.
- Personal guarantee may be required. Fundbox may require a personal guarantee and reserves the right to file a UCC lien on your business — meaning your personal and business assets could be at risk in a default.
Beyond the revolving line of credit, Fundbox’s term loan remains in beta and is available only to select applicants. If you need equipment financing, an SBA loan or other structures, you’ll need to compare other business loan options.

How to qualify for Fundbox
Fundbox discloses clear eligibility minimums for its line of credit:
- Personal credit score of 600 or higher
- At least three months of transaction history in a business checking account (six months recommended for better approval odds)
- Minimum $100,000 in annual revenue
- US-based business
- Not operating in a restricted industry (including adult entertainment, online gambling, marijuana, firearms, nonprofits or financial services)
Meeting these minimums doesn’t guarantee approval. Fundbox uses AI to evaluate your bank account data and financial history holistically. If your credit score is an issue, look into business loans that don’t require a credit check for approval.
How to apply
- Register on Fundbox’s website. Create an account and provide basic business information, including time in business and average monthly revenue.
- Connect your accounts. Link your business checking account and, if applicable, your accounting software. Fundbox uses this data in place of traditional documentation.
- Receive a decision. Fundbox runs a soft credit check at this stage, which does not impact your score. Decisions often come within three minutes, though it can take up to 24 hours.
- Review and accept your offer. If approved, you’ll see your credit limit, term options and full fee breakdown before committing to anything.
- Draw funds as needed. Once accepted, draw funds when you need them. Your first hard credit check occurs on your first draw. Funds typically arrive the next business day.
While you’ll need your login credentials to connect accounts, Fundbox doesn’t store that information. It also uses Norton to make sure the site isn’t compromised and your information is protected.
If you’d prefer less “paperwork” than Fundbox requires, consider a no-doc business line of credit instead.
