Yes, you can use invoice factoring even if a single customer makes up most or all of your revenue. In fact, factoring is often easier to qualify for in this situation than a bank loan, because the factoring company is buying your customer’s promise to pay rather than lending against your balance sheet. What matters most is that one customer’s creditworthiness.
The catch is what the industry calls concentration risk: when one buyer represents a large share of your invoices, the factor’s exposure is tied to that single payer, and that shapes your rate, your advance amount, and sometimes the structure of the deal. Here’s how it works in practice.
What Customer Concentration Means in Factoring
Customer concentration is the share of your total receivables tied to a single customer. A trucking company that runs 80 percent of its loads for one broker, or a staffing agency that places most of its workers at one employer, has high customer concentration. Factors watch this number closely because it measures how much of their risk sits with one paying party.
Most factoring companies start to flag concentration once a single customer passes 20 to 30 percent of your receivables. That doesn’t mean they decline the account. It means they underwrite it differently.
Can You Factor If One Customer Is Most of Your Revenue?
In most cases, yes. Single-customer and high-concentration factoring is common in industries built around anchor clients: freight, staffing, government contracting, and wholesale supply. Factoring companies that specialize in those sectors expect concentration and price for it.
What they care about is whether that one customer pays reliably. Because repayment comes from your customer rather than from you, the factor’s underwriting focuses on the buyer. A business with one rock-solid, creditworthy customer can be an easier approval than a business with twenty shaky ones. Our guide to invoice factoring for small business covers how that customer-focused underwriting works.
How One Customer Changes Your Factoring Terms
Concentration rarely blocks a deal, but it does adjust the terms. Expect some combination of these:
- A modestly higher rate. More risk in one place usually means a slightly higher factoring fee.
- A lower advance on the concentrated portion. Instead of advancing 90 percent, a factor might advance 80 percent against invoices from your dominant customer, holding a larger reserve until payment clears.
- Closer credit monitoring. The factor will watch that customer’s payment behavior carefully and may set an exposure cap on how much it will fund against that single buyer.
- A preference for non-recourse where it fits. Some factors offer non-recourse terms on strong, creditworthy anchor customers, which can protect you if that buyer goes insolvent.
Consider a staffing agency that bills $120,000 a month, with $90,000 of it going to one hospital system. A factor comfortable with healthcare receivables might advance 90 percent on the smaller accounts and 80 percent on the hospital invoices, while monitoring the hospital’s payment record month to month. The agency still gets the working capital it needs to make payroll, just with terms calibrated to the concentration.
When Concentration Becomes a Problem
There is a point where concentration gets harder to fund. A few situations raise real caution:
- The single customer has weak or unknown credit. If the one buyer carrying your business is a poor payer, the entire arrangement is fragile, and factors will hesitate.
- The customer is also financially linked to you. An affiliated or related-party customer doesn’t provide the independent payment risk factoring relies on.
- The relationship is informal or new. A short history with the anchor customer or loose paperwork makes the receivable harder to verify and collect.
Even then, options exist. A factor may fund the account with a lower advance and a tighter exposure cap while you work to diversify, then loosen terms as your customer base broadens.
The Bigger Picture: Diversification Protects You Too
Concentration is a risk for your business, not only for the factor. If 80 percent of your revenue depends on one customer, losing that account is an existential event, factoring or not. Industry analysts generally flag any single customer above 20 percent of revenue as high concentration, the point where one lost account can devastate cash flow. Using factoring to stabilize cash flow while you pursue additional customers is a reasonable strategy. Leaning on it to prop up a dangerously concentrated business indefinitely is not. If your need is really about bridging gaps between large jobs, a business line of credit may complement factoring by giving you flexible capital that isn’t tied to a single buyer.

Frequently Asked Questions
Can you factor invoices from just one customer?
Yes. Single-customer factoring is common in freight, staffing, and government contracting. The factoring company underwrites the strength of that one customer, so a reliable, creditworthy buyer can make for a straightforward approval even when it represents all of your revenue.
What is concentration risk in factoring?
Concentration risk is the exposure a factor takes on when a large share of your receivables comes from a single customer. Most factors begin adjusting terms once one customer passes 20 to 30 percent of your invoices, since their ability to collect depends heavily on that one payer.
Does having one big customer lower my advance rate?
It can. A factor may advance a slightly lower percentage on invoices from your dominant customer, holding a larger reserve until those invoices are paid. Advances on your smaller accounts often stay at standard rates.
Is it harder to get factoring with high customer concentration?
Not necessarily. If your main customer has strong credit and a clean payment history, concentration is manageable and often expected in your industry. It becomes harder only when that single customer has weak credit, an informal relationship with you, or an unproven payment record.
How can I reduce customer concentration over time?
Add customers. Use the steady cash flow factoring provides to fund sales and marketing, take on smaller accounts alongside your anchor client, and gradually spread your receivables across more payers. As concentration falls, factors typically improve your advance rates and fees.
