Invoice Factoring: How It Works, Costs and vs Invoice Financing

Quick answer: Invoice factoring is when a business sells its unpaid invoices to a factoring company for an immediate cash advance, typically a large share of the invoice value. The factor collects payment from the customer, then pays the business the remaining balance minus its fees. It turns slow-paying receivables into cash within days, at a cost.

This guide explains how invoice factoring works step by step, works through a full cost calculation, compares factoring with invoice financing in a table, and covers the alternatives worth trying first. Factoring only works with clean, verifiable invoices, so start with a professional invoice from our free invoice generator and clear payment terms.

This article is general information, not financial advice. Factoring contracts vary widely; read every term and consider independent advice before signing.

How invoice factoring works

1. You invoice your customer as normal for goods or services already delivered.
2. You submit the invoice to the factor, along with supporting documents such as proof of delivery or a signed timesheet. Carriers, for example, attach the signed bill of lading to their trucking invoices.
3. The factor verifies the invoice, often contacting the customer to confirm the amount is owed.
4. You receive an advance, a percentage of the invoice value (the advance rate), usually within a few days.
5. The customer pays the factor directly, using payment details shown on the invoice.
6. The factor pays you the rebate: the invoice value minus the advance and the factor's fees.

Because the factor's money depends on your customer paying, factors care more about your customers' creditworthiness than about yours. That is why factoring is used by young or fast-growing businesses that sell to large, reliable customers on long terms.

Invoice factoring vs invoice financing

The two terms are often mixed up. Factoring is a sale of the invoice; invoice financing (sometimes called invoice discounting or accounts receivable financing) is borrowing secured against it.

Feature	Invoice factoring	Invoice financing
What happens to the invoice	Sold to the factor	Used as security for a loan or credit line
Who collects from customers	Usually the factor	You do
Customer awareness	Usually notified	Often confidential
How you get paid	Advance, then rebate after customer pays	Loan drawn against invoices, repaid when customers pay
Typical cost structure	Factor fee per period the invoice is outstanding, plus possible service fees	Interest or a fee on the amount borrowed, plus possible service fees
Credit control workload	Reduced: outsourced to factor	Unchanged: stays with you
Often suits	Businesses without a credit control team	Established businesses with good collection processes

Worked example: what factoring really costs

The figures below are illustrative, not market rates. Always use the numbers in the offer you receive.

You issue a $20,000 invoice on Net 60 terms. A factor offers an 85% advance rate and a fee of 2% of the invoice value for each 30 days (or part of 30 days) the invoice is outstanding. Your customer pays on day 45.

Step	Calculation	Amount
Invoice value	—	$20,000
Advance paid to you	$20,000 × 85%	$17,000
Fee periods	45 days = one full 30-day period plus a part period	2 periods
Factor fee	$20,000 × 2% × 2	$800
Rebate paid after customer pays	$20,000 − $17,000 − $800	$2,200
Total you receive	$17,000 + $2,200	$19,200

The headline fee is 4% of the invoice, but the true cost is higher once you consider how much money you actually used and for how long. You paid $800 to receive $17,000 about 45 days early:

• Cost relative to cash advanced: $800 ÷ $17,000 = 4.71% for 45 days
• Rough annualized cost: 4.71% × (365 ÷ 45) ≈ 38% per year

Notice the effect of the "part period" rule: if the customer had paid on day 30, you would have paid one period ($400), but paying on day 31 doubles it. Fee schedules, minimum fees and extra charges (setup, verification, bank transfer or termination fees) can change the result a lot, so model your own worst case (a customer paying late) before you commit.

Recourse vs non-recourse factoring

• Recourse factoring: if the customer doesn't pay within an agreed period, you must repay the advance or swap in another invoice. Fees are usually lower because you keep the credit risk.
• Non-recourse factoring: the factor absorbs the loss if the customer becomes insolvent. Fees are usually higher, and "non-recourse" often covers only specific events, not disputes about the quality of your work. Read the definitions carefully.

Pros and cons of invoice factoring

Advantages

• Fast cash tied to sales you have already made
• Approval based mainly on your customers' credit, not your trading history
• Funding grows as your invoicing grows
• Collections can be outsourced

Disadvantages

• Expensive compared with most bank credit when annualized
• Customers deal with a third party, which can affect relationships
• Contracts may require you to factor all invoices, set minimum volumes or impose notice periods
• Disputed invoices can be charged back to you

Is your invoice ready to be factored?

Factors reject invoices that are vague, disputed or hard to verify. Before submitting, check that each invoice:

• Has a unique number in a clean sequence: use our invoice number generator if your numbering is messy
• Names the customer's correct legal entity and quotes any PO number
• Describes delivered goods or completed services, not future work
• Shows a clear due date and the correct payment details (often the factor's account, as instructed)
• Matches your contract and delivery records

A formal layout such as the Corporate invoice template makes verification easier for both the factor and your customer.

Alternatives to try before factoring

Factoring fills a gap between delivering work and getting paid. Often you can shrink that gap more cheaply:

• Invoice the same day work is approved and follow the tactics in how to get paid faster.
• Offer an early payment discount. A 2/10 net 30 discount costs you 2%; see our guide to the early payment discount to compare its implied cost with a factoring offer.
• Take deposits or milestone payments on large jobs with a deposit invoice.
• Enforce agreed late fees where your contract and local law allow. See late payment fees.
• Tighten receivables management with a weekly review, explained in our accounts receivable guide.

If you still need funding, factoring can be a sensible bridge. Treat it as one tool within broader cash flow management, not a permanent fix.

Questions to ask before signing a factoring agreement

1. What is the advance rate, and does it vary by customer?
2. How is the fee calculated: per day, per 10 days or per 30-day period, and on the invoice value or on the advance?
3. What other fees apply? Ask about setup, due diligence, credit checks, bank transfers, minimum monthly volume and early termination.
4. Is it recourse or non-recourse, and exactly which events does any non-recourse cover?
5. Must you factor every invoice, or can you choose individual invoices (sometimes called spot or selective factoring)?
6. How long is the contract and what notice is required to leave?
7. How will the factor contact your customers, and can you review the wording of their communications?
8. What happens with disputed invoices and how quickly are they charged back?

Then compare the answers with the price of offering customers an early payment discount. A 2/10 net 30 discount gives up 2% to be paid 20 days earlier; on the $98 you actually receive for every $100 invoiced, the implied cost is 2 ÷ 98 × (365 ÷ 20) ≈ 37% a year. That is close to the factoring example above, but it involves no contract, no third party and no customer notification. Depending on your customers and margins, either option could be cheaper, so run both calculations with your real numbers.
