You’re sitting at your desk with a factoring contract in front of you. The rep just said, “Your advance rate is 90%, we’ll UCC-file on your receivables, and we use a recourse structure with notification.” You nod like you understand. You don’t — and you’re not alone.
The AR financing industry runs on jargon. Some of it is technical. Some of it sounds intentionally confusing. Either way, not knowing the language costs you money, leverage, and sleep. This guide to AR financing glossary terms defines the 35 words you actually need — grouped into six thematic buckets, written in plain English, and built so you can read any contract with confidence after one pass.
How to Use This Glossary
Skim the category headers to find the AR financing glossary terms you need, or read start to finish as a 10-minute primer. Each term includes a plain-English definition and, where it matters, a “why it matters” note so you know what to watch for in a contract.
The Fundamentals: Core AR Financing Glossary Terms
These six terms form the base layer. Every other word in factoring builds on top of them.
1. Accounts Receivable (AR)
Money owed to your business by customers for products or services already delivered but not yet paid for. If you invoice net-30, every unpaid invoice is an account receivable until the customer pays.
2. AR Financing
An umbrella term for using your unpaid invoices as collateral or an asset to access working capital now. It includes invoice factoring, invoice financing, and AR lines of credit.
3. Invoice Factoring
You sell your invoices to a third party (the factor) at a small discount. The factor advances most of the invoice value in 24-48 hours and collects payment from your customer. It is technically a sale of an asset, not a loan.
4. Invoice Financing
A loan or line of credit secured by your invoices. Unlike factoring, you keep ownership of the invoices and remain responsible for collecting from customers. It appears on your balance sheet as debt.
Factoring vs Financing — The Quick Tell
Factoring sells the invoice. Financing borrows against it. Factoring moves the collections job to the factor. Financing leaves it with you. Same goal, different mechanics — and the word you hear first tells you which one you’re being offered.
5. Receivables
Shorthand for accounts receivable. When a factor says “we’ll file on your receivables,” they mean your entire pool of unpaid invoices from B2B customers.
6. Debtor
In factoring language, the debtor is your customer — the business that owes you money on the invoice. It is not you. This is the single most confusing term for first-timers, because “debtor” usually means the person who borrowed the money.
The Money Terms
These six terms show up in every pricing conversation. If a rep glosses over them, slow them down and make them define each one. For a deeper look at the pricing side, read our breakdown of AR financing rates in 2025.
7. Advance Rate
The percentage of an invoice’s face value the factor wires to you upfront. Typical range: 80-97%. On a $100,000 invoice at a 90% advance rate, you receive $90,000 within 24-48 hours.
8. Factor Rate (Discount Rate)
The fee the factor charges, expressed as a percentage of the invoice face value per period (usually per 30 days). A 2% factor rate on a $100,000 invoice equals $2,000 for the first 30 days.
9. Reserve
The portion of the invoice the factor holds back instead of advancing. It is the mirror of the advance rate. A 90% advance rate means a 10% reserve. The reserve protects the factor against disputes, short payments, and chargebacks.
10. Reserve Release
After your customer pays the invoice in full, the factor releases the reserve back to you — minus the factor fee. This is where you see the second wave of cash from each invoice.
| Step | Amount on $100K Invoice |
|---|---|
| Advance (90%) | $90,000 wired in 24-48 hours |
| Reserve (10%) | $10,000 held by factor |
| Factor fee (2% x 30 days) | -$2,000 |
| Reserve release after customer pays | $8,000 |
| Total received | $98,000 (cost: $2,000) |
11. Effective APR
The annualized cost of your factoring arrangement, calculated as if you were borrowing for a full year. A 2% factor fee on a 30-day invoice annualizes to roughly 24% APR. This number looks scary in isolation — but you are not borrowing for a year. You are bridging a 30-60 day gap.
Watch Out for the APR Trick
Competitors of factoring love to quote the annualized APR to make it look expensive. Compare the real dollar cost to the real alternative — an MCA at 50-150% APR, a credit card at 20% APR, or the cost of missing payroll. Context beats the scary number every time.
12. Minimum Volume Fee
A penalty fee charged if you do not factor a minimum amount per month. Common in whole-ledger contracts. If the floor is $50,000/month and you only submit $30,000, you may owe the factor fee on the $20,000 shortfall as if you had factored it.
The People and Parties
A factoring transaction has more players than most people expect. The contract will name each one, and their roles do not always match what the everyday meanings of the words suggest. If you remember nothing else from this section, remember that the “debtor” is your customer, not you.
13. Factor (Factoring Company)
The company that buys your invoices and advances cash. They handle credit checks on your customers, verify invoices, process payments, and manage collections in most structures.
14. Client (Seller)
That is you — the business selling the invoices to the factor. Sometimes called the “seller” in legal documents because factoring is technically the sale of an asset.
15. Account Debtor
A more formal name for your customer — the business that owes payment on the invoice. On contracts, you will see “account debtor” more often than “customer.”
16. Guarantor
A person — usually the business owner — who personally promises to repay the factor if the business fails to meet its obligations. Guarantors are named on personal guarantees, which we cover in the legal section.
17. Broker
A middleman who matches businesses with factors and earns a commission. Brokers can be helpful for first-time applicants comparing multiple factors, but their commission is often baked into your rate. Always ask if you are working with a direct factor or a broker.
The Contract Terms
The seven words in this group define the shape of your relationship with the factor. Each pair or term is a lever — some protect you, some protect the factor. Know which is which before you sign.
18. Recourse Factoring
If your customer does not pay the invoice (usually within 60-90 days), you have to buy it back from the factor. Lower fees, but the credit risk stays with you. This is the most common structure — about 80% of factoring arrangements.
19. Non-Recourse Factoring
The factor absorbs the loss if your customer goes bankrupt or cannot pay for approved credit reasons. Higher fees (typically 0.5-1% more), but you are off the hook for approved credit losses. Read the fine print — non-recourse usually only covers customer insolvency, not disputes or slow payment. See our full breakdown of recourse vs non-recourse factoring.
20. Notification Factoring
Your customers are told the invoice has been assigned and are directed to pay the factor. Lower rates because the factor controls collections.
21. Non-Notification Factoring
The arrangement is confidential. You keep collecting, then forward payments to the factor. Your customers never know. Higher rates and stricter qualification requirements, but useful if you are worried about how factoring looks to customers.
| Comparison | Cheaper Option | Safer / More Private Option |
|---|---|---|
| Recourse vs Non-Recourse | Recourse (lower fees) | Non-recourse (credit protection) |
| Notification vs Non-Notification | Notification (lower fees) | Non-notification (customer-confidential) |
| Spot vs Whole-Ledger | Whole-ledger (lower per-invoice rate) | Spot (no commitment, more flexibility) |
22. Spot Factoring
Factoring one invoice at a time with no commitment and no monthly minimums. Higher per-invoice fee, but maximum flexibility. Good for seasonal needs or testing a factor.
23. Whole-Ledger Factoring
You factor your entire pool of eligible invoices under a single ongoing contract. Lower per-invoice fees because of the volume, but typically carries minimum volume commitments and longer contract terms.
24. Notice of Assignment (NOA)
A letter sent to your customer telling them the invoice has been assigned to the factor and to pay the factor directly. Standard in notification factoring. Most customers have received NOAs before and do not think twice about it.
The Legal and Risk Terms
These six terms decide what a factor can do to protect their money — and what you are agreeing to let them do. They sound intimidating, but they are standard and mostly harmless in a normal relationship. Knowing them still matters, because they shape what happens if anything goes wrong.
25. UCC-1 Filing
A one-page legal notice filed with your Secretary of State that publicly declares the factor has a secured interest in your receivables. It is how lenders establish priority when more than one is involved. A UCC-1 is not a mark on your credit report — it is a notice, not a judgment. For the underlying law, see the Uniform Commercial Code reference at Cornell Law.
26. Lien
A legal right a lender has over a specific asset. A UCC-1 filing creates a lien on your receivables. If you default, the lender can claim the asset to recover the debt.
27. Perfected Security Interest
Once a factor files a UCC-1 and meets the legal requirements, their lien is “perfected” — meaning it takes priority over later claims on the same asset. First to file, first in line.
28. Subordination Agreement
If you already have a lender with a UCC filing, a new factor may ask that lender to “subordinate” — to agree that the factor’s claim on your receivables comes first. Without subordination, the new factor often cannot start funding.
29. Personal Guarantee
A signed commitment that if the business cannot repay the factor, you personally will. Common at smaller businesses and newer companies. It puts your personal assets on the line, so read it carefully.
Personal Guarantees Deserve a Second Look
Not all personal guarantees are created equal. Some cap your liability. Some are unlimited. Some only apply to “validity” — meaning you guarantee the invoice is real, not that the customer will pay. Ask what type you are signing before you sign.
30. Lockbox
A P.O. box or bank account controlled by the factor where your customers send their payments. The lockbox makes sure payments flow directly to the factor instead of getting deposited in your account and then needing to be forwarded.
The Operational Terms
These five terms describe the day-to-day mechanics once you are funded. They come up constantly — in weekly emails, in your online portal, and in conversations with your factor account manager.
31. Invoice Verification
Before advancing funds, the factor confirms the invoice is real — usually by calling your customer, emailing a verification request, or checking a customer portal. Verification is the single biggest source of funding delays. Clean invoices and cooperative customers keep it fast.
32. Schedule of Accounts
A list of invoices you submit to the factor for funding at one time. Most factors have a standard form. Submitting a clean, accurate schedule speeds up funding by a full day in most cases.
33. Aging Report
A financial report that groups your receivables by how long they have been outstanding — current, 1-30 days, 31-60 days, 61-90 days, and 90+. Factors require a fresh aging report monthly to track exposure and spot slow-paying customers.
34. DSO (Days Sales Outstanding)
The average number of days it takes your customers to pay an invoice. Lower DSO means faster cash. Factors watch DSO because rising DSO signals rising risk. Formula: (Accounts Receivable ÷ Total Credit Sales) × Days in Period.
35. Chargeback (Recourse Event)
In a recourse contract, if your customer does not pay by the agreed deadline, the factor “charges back” the invoice — meaning you have to buy it back at face value. Chargebacks are the main reason recourse factoring costs less than non-recourse: the risk sits with you.
Key Takeaway
Thirty-five AR financing glossary terms. Six categories. One outcome: you can now read a factoring contract, ask sharper questions, and spot which clauses deserve negotiation. The industry runs on jargon because most clients never push back. You just stopped being most clients.
Put These AR Financing Glossary Terms to Work
The best way to lock in this vocabulary is to pair it with the process itself. Pull out your next factoring proposal, circle any unfamiliar words, and match them to the definitions above. If you want to see how these terms flow through an actual funding transaction from start to finish, read our full walkthrough on how AR financing works, step by step.
Most people lose money in factoring not because rates are high, but because they did not know what they were agreeing to. Language is leverage. You just gained some.
Come back to this glossary whenever a new term shows up — on a call, in a contract, in a monthly statement. Over a few weeks, the jargon will start to feel normal. Once it does, your negotiating position improves for free.
