How invoice factoring and a business line of credit compare on cost, approval, repayment and customer control, with a worked example and a simple way to choose.
Quick answer: Invoice factoring means selling unpaid invoices to a company that advances typically 70% to 90% of their value and collects from your customer. A business line of credit lets you borrow as needed and repay with interest. Factoring may be easier to get for newer businesses, while a line of credit often costs less if you qualify.
Both options can help when customers take 30 or 60 days to pay, but they work very differently. One sells an asset and may bring a third party into your customer relationships. The other is debt, which you must repay on schedule. This guide helps you compare them honestly. It is general information, not financial advice, so check the terms of any actual offer.

What Is Invoice Factoring?
With factoring, you sell invoices to a factoring company. It pays you most of the invoice value upfront, usually within a few business days. It then collects from your customer and sends you the remainder, minus fees.
- Recourse factoring: if the customer fails to pay, you must buy the invoice back. This is the most common type.
- Non-recourse factoring: the factor absorbs the loss if a customer does not pay, usually under specific conditions and often for higher fees.
What Is a Business Line of Credit?
A line of credit gives you a limit that you can draw on when you need it. You usually pay interest only on what you use, and you can borrow again as you repay it. It works much like a business credit card, but it often has larger limits and different terms.
Factoring vs Line of Credit at a Glance
| Factor | Invoice factoring | Line of credit |
|---|---|---|
| What it is | Sale of invoices | Revolving debt |
| Approval focus | Your customers’ ability to pay | Your business and personal credit |
| Common requirements | Business-to-business invoices | Often 1 to 2 years in business and a credit score around 600 to 680+ |
| Speed | Often a few days after setup | Depends on the lender |
| Cost | Fees on invoice value | Interest on drawn amounts, plus possible fees |
| Repayment | Customer pays the factor | Required payments from you |
| Customer contact | Factor usually collects | You keep control |
What Does Each One Cost?
Factoring costs
Sources quote different ranges, since providers charge in different ways. QuickBooks puts typical fees at 1% to 5% of the invoice value, and Bankrate describes factor rates of about 0.5% to 4%, which may be charged once or may build over time. Look out for origination, wire, late payment and termination fees as well.
Line of credit costs
You pay interest on your balance, and there may be draw, maintenance or unused-credit fees. Established businesses with strong credit will often pay less overall than they would with factoring, but rates vary widely.
To compare fairly, translate each option into the total dollars paid for the same amount of money over the same period.
Worked Example
You send a customer a $30,000 invoice due in 30 days. A factor charges a total fee of 4%, so your cost is $1,200 and you end up with $28,800. Suppose you instead draw $24,000 from a line of credit at 18% annual interest for one month. The interest is about $360, plus any fees. In this simplified case credit is cheaper, if you can qualify and your customer pays on time.
The picture changes if your customer pays late, because interest keeps growing and some factors charge more over time. Run the numbers using your own rates and realistic payment dates.
Which Should You Choose?
Factoring may fit if:
- You are a newer or lower-credit business with reliable customers.
- You sell to other businesses and often wait a long time to be paid.
- You are willing to let a third party collect payment.
- You have good margins that can absorb the fees.
A line of credit may fit if:
- You have solid credit and some trading history.
- You want to manage your own customer relationships.
- Your need for cash comes and goes through the year.
- You need to fund costs that are not tied to invoices, like inventory.
A staffing firm pays workers weekly but gets paid by clients in 45 days. It has only been trading for eight months, so a bank declines its credit application, while its large corporate clients satisfy a factor. Factoring eats into its margin, yet it keeps payroll running during its growth stage. A year later, it can reassess.
Risks to Watch
- Thin margins: fees can wipe out profit on low-margin work.
- Customer perception: some customers may react badly to a collection company.
- Long contracts: minimum volumes and termination fees can be expensive.
- Personal guarantees: lines of credit often require one, which puts personal assets at risk.
- Required payments: a line of credit must be serviced even if customers pay late.
- Recourse: you may still carry the loss when a customer does not pay.
Ask each provider one question: what is the total cost if my customer pays 30 days late? The answer shows you much more about the deal than the headline rate.
What Are the Alternatives?
- Invoice financing: you borrow against invoices and keep collecting from customers yourself.
- Term loans: these are better for a single, planned investment.
- Better invoicing: earlier billing, reminders and online payments can reduce your need to borrow.
- Early payment discounts: a small discount may be cheaper than financing.
- Business credit cards: useful for small short-term costs, if you pay them off on time.
Be very cautious with merchant cash advances, which can carry high costs and frequent repayments.
How to Compare Offers
- Work out how much cash you need, and for how long.
- Review how quickly your customers really pay.
- Get at least two written quotes for each option.
- List all fees and notice periods.
- Calculate the total cost in dollars.
- Check any personal guarantee with an adviser.
- Choose the cheapest option that matches your actual cash gap.
Open your unpaid invoices and calculate the average number of days your customers take to pay. Use that figure, not your stated payment terms, when you compare financing costs.
Frequently Asked Questions
Is invoice factoring a loan?
Not usually. It is structured as a sale of invoices, though recourse terms mean that you may still carry risk.
Which is cheaper?
A line of credit is often cheaper for established, creditworthy businesses, but you should compare real offers.
Can a startup get factoring?
It may, as factors focus on customer credit, although you normally need invoices from creditworthy business customers.
Will my customers know?
Usually, because they often pay the factor directly. Ask about each provider’s process.
Does factoring affect my credit score?
Bankrate says it does not typically affect your credit score, as approval focuses on your customers. Check each provider’s terms.
Final Thoughts
- Factoring sells invoices, whereas a line of credit is revolving debt.
- Factoring may be easier to access, but it can cost more and affect customer contact.
- A line of credit gives you more control if you can qualify.
- Compare total dollars, including a late-payment scenario.
