Invoice Factoring
Invoice factoring is a way to turn unpaid customer invoices into cash now, by selling those invoices to a factoring company at a discount instead of waiting 30, 60, or 90 days for your customers to pay. It is a cash-flow tool, not a loan against your balance sheet: the money is tied to invoices you have already earned. Custom Capital Advisors is a financing brokerage, so we do not fund the factoring ourselves. We help you decide whether factoring is the right fit, connect you with the right factoring partner, and make sure the terms actually work for your margins before you commit.
What is invoice factoring?
Invoice factoring converts your accounts receivable into working capital. When you invoice a customer on net terms, that money is owed to you but not yet in your account. A factoring company advances you most of the invoice value right away, then collects from your customer directly and sends you the rest, minus its fee, once the invoice is paid. Because the funding is backed by invoices you have already delivered on, factoring often works for businesses that could not yet qualify for a traditional term loan. For a deeper look at how receivables financing works and what it is designed to solve, see our guide on financing against receivables.
How does invoice factoring work?
The flow is straightforward. You deliver your product or service and invoice the customer as usual. You sell that invoice to the factoring company, which advances you a large share of its value up front. When your customer pays on their normal schedule, the factor releases the remaining balance to you and keeps a fee for the service. Most factoring is ongoing: as you generate new invoices, you can factor them too, so the available funding grows and shrinks with your sales rather than being a fixed lump sum.
How much can you get, and what does it cost?
The amount available scales with your invoices, not with a fixed credit limit, so a business with more (and more reliable) receivables can access more capital. The factor advances a portion of each invoice up front and holds the rest as a reserve until the invoice is paid. The cost is a fee based on the invoice amount and how long the invoice takes to get paid, so faster-paying customers cost less to factor. We present advance rates, reserves, and fees as ranges and typical cases, never as a promise, because the real numbers come from the factoring partner once your receivables are reviewed.
How fast can factoring fund?
Once a factoring relationship is set up, individual invoices can often be funded in as little as a day or two, which is why factoring is popular with businesses that need to smooth cash flow between delivery and payment. The initial setup takes longer than a single funding because the factor reviews your customers and receivables first. We help you prepare a clean receivables file so the setup moves as quickly as it reasonably can.
Who is invoice factoring a good fit for?
Factoring tends to fit businesses that invoice other businesses on terms and need the cash before those terms run out. Common fits include manufacturers and wholesale distributors waiting on large buyers, staffing and service firms covering payroll between client payments, and freight and transportation carriers that invoice brokers and shippers on net terms. If your customers are reliable payers and the gap between delivery and payment is straining your cash flow, factoring is often a clean way to close that gap.
Invoice factoring vs your other options
Factoring is one of several ways to solve a cash-flow gap, and it is not always the best one. The right choice depends on whether the need is tied to specific invoices, is recurring and unpredictable, or is a one-time investment. Here is how the common options compare.
| Financing type | Best for | Typical amount | Speed to fund | Repayment | Cost structure |
|---|---|---|---|---|---|
| Invoice factoring | B2B businesses with slow-paying customers | Scales with your unpaid invoices | Often a day or two once set up | Your customer pays the factor directly | A fee per invoice, based on size and time to pay |
| Business line of credit | Recurring or unpredictable short-term needs | A set credit limit you draw against | Fast once approved | Revolving: draw and repay as needed | Interest on what you draw, sometimes a draw fee |
| Asset-based lending | Borrowing against receivables, inventory, or equipment | Tied to the value of pledged assets | Moderate | Ongoing facility | Interest plus facility fees |
| Business term loan | One-time investments with predictable payback | A lump sum | Varies by lender and file | Fixed schedule over months to years | Interest over the term |
If your cash need is tied directly to unpaid invoices, factoring usually fits best. If the need is recurring but not invoice-specific, a line of credit is often more flexible. If it is a one-time investment with a clear payback, a term loan usually costs less over time. Our job is to find the right fit for your business, even when that means pointing you away from factoring. For a side-by-side breakdown, see our guide to invoice factoring vs a line of credit.
If the gap recurs rather than happening once, a factoring line of credit revolves against your receivables instead of funding invoice by invoice.
How do you qualify for invoice factoring?
Factoring qualifies differently from almost every other business financing product, and the difference works in favor of younger companies. Most of the underwriting weight sits on your customers, not on you. A factor is buying the right to collect an invoice, so what matters most is whether the business that owes the money is a reliable payer.
In practice that means factors look at who you invoice, how those customers have paid in the past, whether your invoices are for work already delivered, and whether anything else has a claim on your receivables. Businesses that invoice other businesses on net terms are the natural fit. Businesses paid at the point of sale generally are not, because there is no invoice to advance against.
A few things you do not need: years of history, perfect financials, or a strong balance sheet. What you do need is clean, collectible invoices and customers who pay. Nobody can tell you the answer for your business before your receivables are reviewed, and we will not pretend otherwise. What we can do is look at your aging and tell you honestly whether factoring fits or whether another structure serves you better.
What documents do you need to start invoice factoring?
The file for factoring is lighter than for a term loan, and that is a large part of why it is quick to set up.
Expect to provide an accounts receivable aging report, a list of the customers you want to factor and their contact details, copies of the invoices themselves along with proof the work was delivered, your business formation documents and tax ID, and recent bank statements. Some factors will also ask for a customer contract or purchase order where the work is ongoing.
The aging report is the document that matters most, because it is the one that answers the underwriting question. A clean, current aging with identifiable business customers moves a file quickly. An aging full of very old balances or consumer names raises questions that take time to answer, so it is worth pulling a fresh one before you start rather than sending whatever was last exported.
Does your credit score matter for invoice factoring?
Less than you would expect, and this is the most common misconception about the product.
Your personal and business credit are part of the picture, but they are not the deciding factor. The factor is advancing against money your customer already owes, so your customer's payment history carries more weight than your score does. Businesses that have been declined for a bank loan on credit grounds are often still workable candidates for factoring, and that is one of the main reasons the product exists.
Where your own credit does come up is around liens, judgments, and existing claims on your receivables. If another lender already has a blanket claim on your accounts receivable, that has to be sorted out before a factor can advance against them. That is a structural question, not a score question, and it is one worth raising early rather than discovering three weeks in. For the broader picture of what lenders weigh across every product, see our guide to business loan requirements.
Which industries use invoice factoring most?
Factoring follows net terms, so it concentrates wherever businesses deliver first and get paid later.
Manufacturers factor when a large purchase order ties up materials and labor months before the buyer pays. Wholesale distributors factor to keep restocking while retail and institutional accounts run on their own payment cycles. Freight and transportation carriers factor broker and shipper invoices, which is one of the oldest uses of the product. Professional and staffing firms factor to cover payroll in the gap between placing people and getting paid for them. Commercial construction firms factor progress billings, though retainage terms make the structure worth reviewing carefully. Medical practices and healthcare suppliers factor insurer and facility receivables, where payment cycles are long and predictable.
If your industry is not on this list, that does not rule you out. The question is always the same one: do you invoice other businesses on terms, and do those businesses pay?
When invoice factoring is the wrong fit
We will say this plainly, because it is where the fee can quietly eat your margin. Factoring is usually the wrong fit when your customers are consumers rather than businesses, when your margins are too thin to absorb a per-invoice fee, or when your receivables are slow, disputed, or concentrated in one shaky payer. It is also the wrong tool if what you actually need is long-term capital for growth, in which case a term loan or an SBA loan usually serves you better. If factoring would cost you more than the cash-flow relief is worth, the honest move is to say so, and we will.
