Invoice Financing vs Line of Credit: Costs Compared
Invoice financing vs a business line of credit: how each works, a cost example with real arithmetic, who qualifies and which suits your working capital.
Quick answer: Invoice financing lets you borrow against unpaid invoices, typically receiving a large share of their value upfront and repaying when customers pay. A business line of credit lets you draw cash up to a limit for any purpose and pay interest only on what you use. Invoice financing is easier to qualify for; a line of credit is usually cheaper.
Both are working capital tools designed to bridge the gap between paying your costs and getting paid by customers. They suit different situations, and their pricing is presented so differently that comparing them takes some arithmetic. This guide explains how each works, puts them side by side with a worked cost example, and helps you decide which fits.

What is invoice financing?
Invoice financing (also called invoice discounting or accounts receivable financing) is a loan or credit facility secured on your unpaid B2B invoices. The basic flow:
- You deliver work and issue an invoice on normal terms, such as Net 30 or Net 60.
- You submit the invoice (or your whole receivables ledger) to the lender.
- The lender advances a percentage of the invoice value, the advance rate.
- Your customer pays you as normal, often into an account the lender controls.
- The lender deducts the advance and its fees and releases the balance to you.
Some providers fund individual invoices you choose (often called selective or spot invoice financing); others take your whole sales ledger and set a facility limit. Selective funding costs more per invoice but avoids long contracts. Unlike factoring, you keep control of collections, and the arrangement is often confidential, so customers may not know. Because the lender is relying on your customers paying, it cares about their credit quality and about your invoices being clean, accurate and undisputed.
What is a business line of credit?
A business line of credit is a revolving facility from a bank or online lender. You get a limit, draw what you need, repay, and draw again. Interest is charged only on the outstanding balance, usually as an annual percentage rate (APR), sometimes with an annual fee or draw fees. Lines can be unsecured or secured on business assets, and small business lines often require a personal guarantee.
A line of credit is not tied to specific invoices. You can use it for payroll, stock, a tax payment or a seasonal dip. The lender's decision rests on your business: time trading, revenue, profitability, credit history and existing debt.
Invoice financing vs line of credit: side by side
| Feature | Invoice financing | Business line of credit |
|---|---|---|
| Secured on | Your unpaid invoices | Business assets, a guarantee, or unsecured |
| Amount available | Rises and falls with your receivables | Fixed limit, reviewed periodically |
| Approval based mainly on | Your customers' credit and invoice quality | Your business's credit, history and profits |
| Typical pricing | Fee per period an invoice is outstanding, plus service fees | APR on the balance drawn, plus possible annual or draw fees |
| Use of funds | Tied to invoiced sales | Any business purpose |
| Who collects from customers | You | You |
| Admin | Submit invoices or ledger reports regularly | Minimal once set up |
| Best for | B2B businesses growing fast, with reliable customers on long terms | Established businesses with steady profits |
Worked example: what each option costs
You have $50,000 of invoices to large customers on Net 60 terms and need cash now for payroll. You expect payment in about 45 days. The figures below are illustrative only.
Option A: invoice financing
Offer: 85% advance, fee of 1.5% of invoice value per 30 days or part period.
| Step | Calculation | Amount |
|---|---|---|
| Advance | $50,000 × 85% | $42,500 |
| Fee periods | 45 days = one full 30-day period plus a part period | 2 |
| Fee | $50,000 × 1.5% × 2 | $1,500 |
| Cost as share of cash used | $1,500 ÷ $42,500 | 3.53% for 45 days |
| Rough annualized cost | 3.53% × (365 ÷ 45) | about 28.6% a year |
Option B: line of credit
Offer: 12% APR on the balance drawn, no draw fee. You draw the same $42,500 for 45 days.
| Step | Calculation | Amount |
|---|---|---|
| Interest | $42,500 × 12% × (45 ÷ 365) | $628.77 |
| Annualized cost | APR, no extra fees | 12% a year |
The line of credit costs $1,500 − $628.77 = $871.23 less for the same cash over the same period. Notice two things. First, invoice financing fees quoted "per month" look small but annualize high, especially with part-period rounding: if the customer paid on day 30 instead of day 45, the fee would halve to $750. Second, the comparison assumes you can actually get a 12% line with a $42,500 limit, which many young businesses cannot. Add any annual fee, arrangement fee or minimum monthly charge to both options before deciding.
Who qualifies for each?
Invoice financing usually requires
- B2B sales on credit terms (consumer invoices rarely qualify)
- Creditworthy customers, often with no single customer dominating your ledger
- Clean invoices for completed work, without disputes or contra arrangements
- Reliable records, such as an up-to-date aging report
A line of credit usually requires
- A minimum trading history and revenue level set by the lender
- Acceptable business and often personal credit
- Financial statements or bank statements
- Sometimes collateral or a personal guarantee
When invoice financing is the better choice
- You are growing quickly and your receivables grow with you; the facility scales automatically.
- Your customers are large and reliable but pay on long terms such as Net 60 or Net 90.
- You do not yet have the trading history a bank wants for a line of credit.
- You want to avoid a personal guarantee (check the terms; some invoice finance agreements still ask for one).
When a line of credit is the better choice
- You qualify for a reasonable rate and want the cheapest flexible funding.
- Your cash need is not tied to invoices, such as buying stock before a busy season.
- You sell mainly to consumers, so there are no B2B invoices to borrow against.
- You want minimal ongoing admin.
Other working capital options compared
Invoice financing and lines of credit are not the only choices. The table below summarizes common alternatives in general terms; terms vary widely by lender and country.
| Option | How it works | Typical fit | Watch out for |
|---|---|---|---|
| Invoice factoring | Sell invoices; the factor collects | Businesses without a credit control team | Customer notification, higher cost |
| Term loan | Lump sum repaid in fixed instalments | One-off investments such as equipment | Paying interest on cash you are not using |
| Government-backed loans (for example U.S. SBA 7(a)) | Bank loan partly guaranteed by a government agency | Established businesses that can wait for approval | Paperwork and approval time |
| Business credit card | Revolving card credit | Small, short-term purchases | High rates if not cleared monthly |
| Merchant cash advance | Advance repaid from a share of card sales | Card-heavy retail and hospitality | Very high effective cost |
In the US, the Small Business Administration describes its loan programs, which lenders offer with an SBA guarantee. Whatever the product, convert the offer to an annualized cost on the cash you will actually use, as in the worked example above.
Checklist before you apply
- A current 13-week cash forecast showing how much you need and when you can repay.
- An up-to-date aging report with disputed invoices identified.
- Recent financial statements and bank statements.
- Copies of key customer contracts and any purchase orders.
- A list of existing loans, guarantees and security already given.
- Invoices with unique numbers, correct customer legal names and clear due dates.
Common mistakes when choosing working capital finance
- Comparing a monthly fee with an annual rate. Convert everything to an annual cost on the cash you use.
- Ignoring the small print: minimum volumes, all-ledger requirements, termination fees and notice periods.
- Borrowing to cover a pricing problem. If you are short every month, finance only delays the issue. Check your margins with our markup vs margin guide.
- Drawing a line of credit to the limit for months. A revolving line works best for short dips that repay quickly.
- Sending invoices a lender cannot verify. Missing PO numbers, vague descriptions or wrong customer names cause delays or rejections.
Cheaper alternatives to try first
Before paying for finance, try to shrink the gap itself. Invoice on completion, take deposits on large jobs, offer an early payment discount, chase overdue invoices promptly and negotiate shorter terms with new customers. A 13-week cash flow forecast shows how much funding you actually need and for how long, which keeps any facility small.
Next step
Write down the amount and duration of your cash gap from your forecast, then ask for quotes from at least one invoice finance provider and one line of credit lender. Convert both to an annualized cost using the formulas above. Whichever you choose, lenders fund clean invoices fastest: create yours in the invoice generator with the corporate template, with a clear due date, PO number and payment details.
Frequently asked questions
Is invoice financing easier to get than a line of credit?
Often, yes. Invoice financing is secured by your receivables, so lenders focus on the creditworthiness of your customers and the quality of your invoices. A bank line of credit usually depends more on your own trading history, profits, credit score and sometimes personal guarantees. Young businesses with strong customers may qualify for invoice financing first.
Does invoice financing affect my credit score?
It can. Applications may involve a credit check, and some lenders report the facility. Missed repayments on any business credit can harm your business or personal credit, especially if you signed a personal guarantee. Ask each provider what checks they run and what they report before applying.
Can I have both invoice financing and a line of credit?
Sometimes, but many invoice finance agreements take security over your receivables, and a bank may also want that security for a line of credit. Two lenders cannot both have first claim on the same assets without an agreement between them. Disclose existing facilities and read the security terms carefully.
What is accounts receivable financing?
Accounts receivable financing is another name for borrowing against your unpaid invoices. It covers invoice financing (also called invoice discounting) and, loosely, factoring. In financing you keep collecting from customers; in factoring you sell the invoices and the factor usually collects.
Which is cheaper, invoice financing or a line of credit?
Usually a bank line of credit, when you can get one, because it is priced as an annual interest rate on what you draw. Invoice financing fees often look small per month but annualize higher. Convert every offer to a cost per year on the cash you actually use, and include all fees, before you compare.
What advance rate can I expect from invoice financing?
Advance rates commonly fall somewhere around 70% to 90% of the invoice value, although some providers advertise more and others less. The rate depends on your customers' credit, your industry, how often invoices are disputed and the length of your payment terms. The remainder, minus fees, is paid to you when the customer pays. Compare offers on total annualized cost, not just the headline advance.
What happens if my customer never pays a financed invoice?
Under a recourse arrangement, which is the most common type, you must repay the advance and fees or replace the invoice with another one. Under non-recourse terms, the lender takes on some of the credit risk, often only if the customer becomes insolvent, and charges more for it. Read exactly which risks a non-recourse agreement covers, because disputes and simple late payment are often excluded.
How fast can invoice financing pay out?
Once your account is set up, many providers advertise funding within one or two business days of approving an invoice. The first setup takes longer, because the lender checks your business, your customers and sometimes your contracts and aging report. A business line of credit can be quicker to draw once it is in place, but applying for one often involves more paperwork up front.
Can freelancers and sole traders use invoice financing?
Often, yes, if you invoice other businesses on credit terms. Some online platforms fund individual invoices for small businesses and sole traders, while larger whole-ledger facilities may set minimum turnover levels. Invoices to consumers rarely qualify. Lenders look closely at your client's creditworthiness, so an invoice to a large, reliable company is easier to fund than one to a small startup.
Does a business line of credit expire?
Often, yes, or at least it gets reviewed. Lines of credit are commonly reviewed or renewed periodically, often once a year, and some have a fixed draw period followed by a repayment period. The lender can usually reduce or freeze the limit if your finances weaken. Check the review date, renewal fees and conditions in the agreement, and avoid relying on a line of credit as permanent funding.
