Fundbox is different from factoring in one fundamental way: Fundbox lends you money you repay yourself, while factoring sells your unpaid invoices to a third party who then collects from your customers. Fundbox gives you a revolving line of credit underwritten mostly on your connected bank account and accounting data — you draw what you need, repay it in fixed weekly installments, and your customers never know a lender is involved. Factoring is not a loan at all; you assign specific invoices to a factor at a discount, receive most of the face value up front, and the factor takes over the collections relationship. The practical consequences — who contacts your customers, whether the balance revolves, how pricing works, and what happens if a customer pays late — flow directly from that distinction. Below we break down each mechanism as an underwriter would, and where a revenue-based advance fits when neither Fundbox nor a factor is the right tool.
Key takeaways
- Fundbox is a revolving line of credit you repay from your own bank account; factoring sells your invoices to a third party who collects from your customers.
- Fundbox is invisible to customers; traditional factoring usually notifies them to pay the factor directly.
- Fundbox underwrites your bank cash flow and accounting data; factoring underwrites your customers' creditworthiness.
- No B2B invoices on net terms means factoring is off the table — a line or revenue-based advance fits instead.
- With recourse factoring, unpaid invoices come back to you; only non-recourse covers certain defaults, and narrowly.
- Factoring cost grows the longer a customer takes to pay; Fundbox charges a fixed fee per draw over a set term.
- A revenue-based advance (min ~$10,000, FICO 500+, often 24–48h) fits when you need a lump sum but have no factorable invoices — never guaranteed.
The core mechanism: a line of credit vs. selling receivables
Everything else is downstream of this. Get it right and the rest of the comparison is easy.
Fundbox is a short-term revolving line of credit. You connect your business checking account (and optionally your accounting software), Fundbox evaluates your cash-flow patterns, and you're assigned a credit limit. When you draw, funds hit your account — often next business day — and you repay in equal installments over a fixed term (commonly 12 or 24 weeks). As you repay, your available credit replenishes. The money is a debt you owe and repay from your own operating account. Your customers are never contacted and never see Fundbox anywhere.
Factoring is the sale of an asset. You take a specific unpaid invoice — say your customer owes you money on net-30 terms — and you sell (assign) that invoice to a factoring company. The factor advances you a large share of the face value right away (commonly 80–90%), then waits for your customer to pay. When the customer pays the factor directly, you get the remaining reserve back, minus the factor's fee. It's not borrowing; you're converting a receivable into cash today at a discount. Because the factor now owns the invoice, the factor typically manages collection on it.
So the one-line test: Do you repay the money, or does your customer pay a third party? If you repay it, it behaves like Fundbox (a loan/line). If your customer pays someone else, it's factoring.
Who talks to your customers — and why it matters
This is the difference business owners feel most, and it's frequently the deciding factor.
With Fundbox, the financing is invisible to your customers. You keep invoicing and collecting exactly as you do today. No notification of assignment, no lockbox, no third party emailing your accounts-payable contacts. If protecting the customer relationship or keeping your financing private matters to you, this is a real advantage.
With traditional (notification) factoring, your customers are told to remit payment to the factor, and the factor may follow up on late invoices. A professional factor handles this courteously, and for some owners outsourcing collections is a benefit — it's one less back-office job. But it does put an outside party in front of your customers, and some customers read "you sold your invoices" as a sign of financial stress, fairly or not. Non-notification factoring exists and hides the arrangement, but it's harder to qualify for and usually reserved for stronger, larger accounts.
Underwriter's note: if your customers are large, slow-paying enterprises or government agencies, a factor who professionally chases those receivables can be genuinely valuable. If your customers are small, relationship-driven, or repeat local accounts, the intrusion often isn't worth it — a line like Fundbox keeps you in control of the relationship.
What you actually qualify on
The two products underwrite very different things, which is why one may approve you when the other won't.
Fundbox underwrites you — your business's bank-account cash flow and, if connected, your accounting/invoicing history. It wants to see consistent deposits and healthy account activity. It generally does not hinge on your customers' credit. This makes it accessible to newer businesses and to companies whose customers are consumers or small firms (i.e., businesses that don't even have factorable B2B invoices).
Factoring underwrites your customers. The factor is betting on whoever owes the invoice, so the creditworthiness of your customers (the account debtors) matters more than your own credit. That's why factoring can work for a thinly-capitalized business with a shaky owner FICO but blue-chip customers — and why it doesn't work at all if you invoice consumers or bill on cards up front. Factoring requires genuine B2B invoices on terms.
Quick screen: No B2B invoices on net terms? Factoring is off the table — you'd look at a line like Fundbox or a revenue-based advance instead.
How the pricing works (and why they're hard to compare)
The costs are structured so differently that a simple rate-vs-rate comparison misleads.
Fundbox charges a clearing fee on each draw, spread across the repayment term. You know the total cost of a draw before you take it, and the cost is tied to how long you borrow — repaying doesn't change your customer's behavior, only yours. Think of it as a fixed cost of cash for a fixed period, replenishing as you repay.
Factoring charges a discount fee that usually accrues with time the invoice stays unpaid — often a percentage per period until your customer pays. So your cost is partly hostage to your customer's payment speed: a customer who pays in 20 days costs you less than one who drags to 75 days. Factors may also layer in additional service or wire fees, and the recourse structure matters (see below).
The honest takeaway: don't reduce either one to a single "APR" and call the cheaper number the winner. Fundbox's cost is predictable and self-controlled; factoring's cost floats with your customers' habits. Price the tool against the job.
Recourse, risk, and what happens when a customer doesn't pay
This is where the loan-vs-sale distinction has teeth.
Under Fundbox, you owe the balance regardless of what any customer does. If a client stiffs you, that's your problem to collect — but your Fundbox repayment obligation was never tied to that invoice in the first place. It's a debt on your books.
Under recourse factoring (the common kind), if your customer ultimately doesn't pay the factored invoice, you have to buy it back or swap in another invoice. You did not truly offload the credit risk — you got early cash and a collections service, but the default risk boomerangs to you. Under non-recourse factoring, the factor eats certain defaults, but the definition of a covered default is narrow (usually only customer insolvency, not slow-pay or disputes), and you pay more for that protection. Read the recourse terms before assuming risk has transferred.
Decision framework: which tool fits your situation
Use this as a fast triage before you talk to anyone.
Choose Fundbox (a line of credit) if:
- You want financing your customers never see and you keep your own collections.
- You need a revolving buffer you can draw and repay repeatedly, not a one-time invoice sale.
- Your customers are consumers or small businesses, or you bill by card up front (no factorable invoices).
- Your own bank-account cash flow is healthy and consistent, even if your business is young.
Choose factoring if:
- You have real B2B invoices on net-30/60/90 terms and are drowning in the gap between delivering work and getting paid.
- Your customers are large, creditworthy, and slow — and you'd happily hand off chasing them.
- Your own credit is weak but your customers' credit is strong.
- You're comfortable with a third party contacting your customers about payment.
Consider a revenue-based advance instead if:
- You need a meaningful lump sum quickly (min around $10,000) and don't have clean invoices to factor.
- Your credit is bruised (FICO 500+) but your deposits are strong — approval leans on bank deposits and revenue over credit score, often with funding in 24–48 hours.
- You want a marketplace to shop multiple offers against your revenue rather than a single lender's box. See our merchant cash advance overview for how repayment and pricing work.
Note: nothing here is guaranteed — every option is subject to underwriting.

Illustrative only — figures are labeled "for example" and will vary by profile, term, and provider. Nothing below is an offer.
| Factor | Fundbox (line of credit) | Invoice factoring | Revenue-based advance (marketplace) |
|---|---|---|---|
| What it is | Revolving line you draw & repay | Sale of specific invoices | Advance repaid from future revenue |
| Repaid by | You, from your bank account | Your customer, to the factor | You, via a set share/fixed remittance of sales |
| Customers notified? | No | Usually yes | No |
| Underwrites | Your bank cash flow / accounting data | Your customers' credit | Your deposits & revenue (FICO 500+ ok) |
| Typical speed | Often next business day per draw | 1–3 days once set up | For example, 24–48 hours |
| Best when | You want a private, revolving buffer | You have slow-paying B2B invoices | You need a lump sum, no clean invoices, bruised credit |
| Cost driver | Fixed fee per draw over the term | Discount that grows the longer a customer takes to pay | Factor rate on the advance; paid from cash flow |
The point of the table isn't to crown a winner — it's to show that these tools solve different problems. Match the tool to your invoicing reality and your credit profile.
Frequently asked questions
Is Fundbox a type of factoring?
No. Fundbox is a revolving line of credit you repay yourself from your bank account. Factoring is the sale of your unpaid invoices to a third party who collects from your customers. They are structurally different: one is borrowing, the other is selling an asset.
Will my customers know if I use Fundbox?
No. Fundbox is invisible to your customers — you keep invoicing and collecting exactly as you do now. Traditional factoring, by contrast, usually notifies your customers to pay the factor directly.
Do I need invoices to use Fundbox?
Not necessarily. Fundbox underwrites your business bank-account cash flow and, optionally, connected accounting data. That means businesses without factorable B2B invoices — including those billing consumers or taking card payments — can still qualify. Factoring, on the other hand, requires genuine B2B invoices on net terms.
Which is cheaper, Fundbox or factoring?
It depends on your situation, and the two price differently enough that a single rate comparison misleads. Fundbox charges a fixed fee per draw over a set term, so the cost is predictable and controlled by you. Factoring charges a discount that typically grows the longer your customer takes to pay, so your cost partly depends on your customers' payment habits. Price each against the job it does rather than by headline rate.
What happens if a customer doesn't pay?
With Fundbox, you owe your balance no matter what any customer does — the repayment was never tied to a specific invoice. With recourse factoring (the common kind), an unpaid factored invoice comes back to you to buy back or replace. Only non-recourse factoring absorbs certain defaults, and it usually covers only customer insolvency, not slow payment or disputes.
My credit is weak but I have strong customers — what should I use?
That profile often fits factoring, because a factor underwrites your customers' credit more than your own. If you don't have clean B2B invoices, a revenue-based advance may fit instead — approval leans on your bank deposits and revenue rather than credit score, and profiles with FICO 500+ are commonly considered.
I need a fast lump sum but have no factorable invoices. What are my options?
A revenue-based advance through a marketplace is built for this: minimums start around $10,000, approval is driven by bank deposits and revenue over credit, and funding can happen in roughly 24–48 hours. It's repaid from a share of your future sales rather than by selling invoices. Nothing is guaranteed, but it fills the gap when neither a line nor factoring fits.
Can I use both a line of credit and factoring?
Sometimes, but factoring agreements often require a lien on your receivables, which can conflict with a lender's claim on the same assets. If you're stacking financing, disclose everything to each provider up front — undisclosed liens can trigger default. When in doubt, have the intercreditor terms reviewed before signing.
