Here’s the short answer. Invoice financing turns unpaid B2B invoices into cash now. A business line of credit gives you a limit you can draw from for almost any business cost. Pick invoice financing when slow paying customers are the problem. Pick a line of credit when your costs are uneven and your revenue and credit are steady.
Both fill cash flow gaps. They differ in what backs the money, who qualifies, and how the cost is quoted. For the basics on lines, read my business line of credit guide.

How Invoice Financing Works
Invoice financing unlocks cash tied up in invoices your customers haven’t paid yet. There are two main versions, and they are not the same thing.
- Invoice factoring. You sell the invoice to a factoring company. It pays you part of the value now and the rest, minus its fee, when your customer pays. The factor often collects from your customer directly.
- Invoice financing or discounting. You borrow against the invoice. You keep the customer relationship and repay the provider when the invoice is paid.
The provider sets the advance amount and the fee. Both depend on your customers’ payment history and how long your terms run. Check whether the deal is recourse, which means you may have to buy back invoices your customer never pays. My guide to non recourse factoring covers the difference, and invoice discounting vs factoring goes deeper on the two versions.
Example (illustrative numbers only): A manufacturer has $200,000 in invoices due in 45 days. If a provider advances 85%, the business gets $170,000 now. The balance, minus fees, arrives when its customers pay. Real advance rates and fees come from each provider’s offer.
Usually a fit for: B2B companies on net 30 to 90 terms, with customers that pay reliably. Think staffing agencies, manufacturers, wholesalers, freight and logistics, and agencies with long billing cycles.
How a Business Line of Credit Works
A business line of credit gives you a set limit. You draw what you need, pay interest only on what you’ve drawn, and the limit frees up again as you repay. The SBA calls lines of credit the most flexible way for businesses to manage working capital, because interest is only charged when the money is in use.
Lenders size a line on your revenue, bank deposits, time in business and credit. My line of credit requirements guide lists what they check. To see how payments move as you draw and repay, see my business line of credit calculator.
Example (illustrative numbers only): A retail store with a $50,000 line draws $10,000 in a slow month to cover payroll and rent. When sales pick up and it repays, the full $50,000 is available again.
Usually a fit for: businesses with steady revenue and solid credit that face uneven costs, such as retail, restaurants, seasonal services and ecommerce.
Invoice Financing vs Line of Credit: Key Differences
| Factor | Invoice financing | Business line of credit |
|---|---|---|
| What backs it | Your unpaid B2B invoices | Your revenue, credit and sometimes collateral |
| How much you can get | Grows and shrinks with your invoices | A set limit the lender reviews over time |
| Who qualifies | Leans on your customers’ payment record, so newer firms can fit | Leans on your own revenue, time in business and credit |
| Repayment | Comes from your customer’s payment | You repay draws plus interest on a schedule |
| Use of funds | Cash from invoices you’ve already earned | Almost any business cost |
| How cost is quoted | Usually a fee on the invoice value | Usually interest on what you draw, plus any draw or maintenance fees |
| Debt or not | Factoring is a sale of invoices; invoice loans are debt | Debt |
Credit Line vs Invoice Financing: Which Fits Your Situation?
| Your situation | Usually a better fit | Why |
|---|---|---|
| Customers pay on 30 to 90 day terms and are creditworthy | Invoice financing | Funding is tied to invoices you have already earned |
| You need cash for payroll, inventory and surprises | Line of credit | You can draw and repay as needs come up |
| Newer business with limited credit history but strong B2B customers | Invoice financing | Your customers’ credit can carry much of the weight |
| Steady revenue and a solid bank statement history | Line of credit | Lenders reward predictable deposits with reusable access |
| Mostly retail or card sales with few invoices | Line of credit | There are no receivables to finance |
| Large one time contract you need to staff up for | Either, or both | Invoices cover the receivable gap; a line covers costs before you invoice |

How to Compare the Cost
This is where most owners get tripped up. A line of credit quotes interest as a yearly rate. Invoice financing usually quotes a fee on the invoice. A fee that looks small can be a high yearly cost if your customer pays in 30 days, so compare on the same basis.
- Ask for an APR estimate on every offer. New York’s Financial Services Law section 806 requires factoring providers covered by the law to show an estimated APR, the finance charge and the total payment amount when they make a specific offer. Even outside New York, you can ask for the same numbers.
- Count every fee. On invoices: setup, service, wire and late payment fees. On lines: draw fees, maintenance fees and any renewal fee.
- Match the time frame. Price both for the same amount over the same number of days.

The Middle Ground: A Line Backed by Receivables
You don’t always have to choose. Some lines of credit are sized on your receivables and inventory. These are often called asset based lines.
The SBA’s Working CAPLine is one example. It is a revolving line based on your short term assets, repaid as you turn those assets into cash. The SBA says it is generally used by businesses that sell on credit to other businesses. Because the lender has to monitor the collateral, extra fees may apply. The SBA’s 7(a) Working Capital Pilot offers monitored lines up to $5 million. The SBA points it to businesses with at least one year of operating history that can produce receivable and payable agings.
Why Some Businesses Use Both
Some businesses run both. Invoice financing covers the wait on large invoices. A line covers costs that don’t tie to an invoice, like rent, repairs or a new bid.
Example: A construction firm finances its outstanding project invoices and keeps a line open for equipment repairs. I cover this in more detail in get paid faster with invoice financing.
One caution. Both providers may want a lien on your receivables. Read my explainer on a blanket lien, and tell each provider about the other before you sign.
Where to Compare Offers
You’re not alone in shopping around. In the Federal Reserve Banks’ 2025 Small Business Credit Survey, 38% of small employer firms applied for a loan, line of credit or merchant cash advance in the prior 12 months. Only 42% of applicants got the full amount they asked for.

FAQs
Is invoice financing cheaper than a line of credit?
It depends on the offer and how fast your customers pay. Invoice fees are often quoted per invoice, not per year, so ask each provider for an APR estimate and compare them side by side.
Is invoice factoring a loan?
Factoring is a sale of your invoices, not a loan. Invoice financing that you repay is a loan secured by your invoices.
Can a new business get a line of credit?
Some can, but it’s harder. Lenders weigh time in business, revenue and credit. See my guide to a line of credit for startups. Invoice financing can be easier if your customers have strong payment records.
Will my customers know I use invoice financing?
With factoring, often yes, because the factor may collect from them. With invoice discounting, you usually keep collecting yourself. Ask each provider how it handles collections.
