Invoice factoring is a financing solution that allows businesses selling products or services to other organizations to convert their accounts receivable into immediate capital. Rather than waiting 30, 60, or 90 days for customers to pay, a business sells its invoices to a third-party company, known as a factor, at a discount and receives a large percentage of the invoice value upfront.
The appeal is near short-term working-capital speed at a defined cost, funded first against the credit of the account debtor. The seller still matters for fraud risk, dilutions, concentration, and operations, but the facility is not underwritten like a conventional loan against the seller’s own balance sheet. For companies with strong customers and uneven cash conversion, factoring provides capital without adding debt. Because approval is driven primarily by the quality of the receivables and the customers behind them, it can remain available when a traditional credit line is constrained. And because factoring does not add debt to the balance sheet, it can strengthen a business’s financial position while fueling growth.
Many variables drive the cost of financing when factoring invoices. Two numbers set the structure: the factoring rate, the fee the factor charges for purchasing the receivables, and the advance rate, the percentage of the invoice face value paid.
Both numbers, and the variables that move them, are defined below.
Definitions and Considerations
Factoring rate (also discount rate)
This is the fee the factor charges for purchasing the receivables, expressed as a percentage applied to the face value of each invoice. For example, if the factoring rate is 2% and the invoice factored is $100,000, the factoring fee will be $2,000. This rate typically covers most of the factoring company’s funding and administration costs.
Factoring rates are often structured to accrue over the period an invoice remains outstanding, such as a set percentage per 30-day period, rather than as a single flat charge regardless of timing. The clock usually starts when the invoice is purchased or funded by the factor, not on the original invoice date, so aging that occurred before submission is typically not billed as factoring time.
Similarly to how interest accrues on a loan balance, the longer a customer takes to pay after funding, the more the fee can build. Some factors charge the first period as 30 days and then accrue in shorter increments, sometimes 15 or 20 days, at a lower rate than the initial period.
Total financing cost is therefore a function of both the rate and how quickly invoices are actually collected.
Advance rate
This is the percentage of the invoice value paid upfront by the factor to the business. The remaining portion is released once the factor collects payment from the business’s customers.
Rate adjustments, turns, volume, and concentration
Factoring rates are based on total transaction volume, concentration (number of clients), timing of payments (turn: how quickly clients pay factored invoices), and the credit rating of both the client and the client’s ultimate customers. Higher volume, faster payments, and diversification across customers all decrease risk, and rates tend to improve over time as these variables improve. Conversely, higher concentration among fewer customers, or customers in higher-default industries, typically triggers higher factor rates, lower advance rates, or both.
Reserve
The reserve is the difference between the face value of the invoices and the advance amount. It is the portion held back until the factor receives payment on that invoice. Larger reserves sometimes result in lower factoring rates, as the factoring company’s risk is lower.
Eligible receivables
Not every invoice can be factored. Eligible receivables are typically earned, billed, undisputed, and assignable, and they fall within the factor’s aging and customer limits. Progress billings, unearned work, and invoices already past the factor’s aging cutoff are often ineligible or reserved more heavily.
Method of payment fees (ACH, wire transfer, etc.)
When applicable, payment fees are typically nominal and vary depending on the lender. Regular ACH payments are the most common and are either free or inexpensive. Wire transfers generally carry a higher fee but settle more quickly.
Added fees
Some factoring companies may charge other processing fees, including for setup (one-time), chargeback, expedited processing, and similar items. Such fees are generally listed in the security agreement and must be reviewed before signing.
Recourse vs. non-recourse
In a recourse facility, the business remains responsible if an account debtor does not pay. In a non-recourse facility, the factor assumes a defined portion of credit risk on approved debtors, usually limited to insolvency rather than disputes, returns, or short pays. Non-recourse typically costs more and is underwritten more tightly against the customer file. Confirm what events are actually covered before treating a facility as non-recourse.
Notification vs. non-notification
Most facilities are notification factoring: the customer is directed to pay the factor. Non-notification arrangements exist but are less common and are usually reserved for stronger files. Notification is an operating issue, not only a legal one, because it changes collections and customer communication.
Typical term ranges
Advance rates commonly fall in the 70% to 90% range. Factoring rates often fall in the 1% to 3% range per 30-day period. Riskier files, including those with higher concentration, slower turns, weaker debtor credit, or more operational noise, can price above that range. Those bands are starting points, not a quote. Higher volume, faster turns, better debtor quality, and lower concentration move a file toward higher advances and lower rates. Quoted terms are file-specific. Facilities are often written for about a year and renew. The fee clock runs invoice by invoice.
Example: How the Numbers Work Together
To see how these terms apply together, consider a $200,000 invoice factored at a 90% advance rate and a 2% factoring rate charged per 30-day period.
At the time of sale, the business receives an advance of $180,000 (90% of $200,000), with the remaining $20,000 held back as a reserve. If the customer pays in 25 days, the factor would bill for one 30-day period, resulting in a factoring fee of $4,000. If the customer pays in 55 days, the factor would bill for two 30-day periods, resulting in a factoring fee of $8,000 (two periods at 2% each).
In the former case, when the customer pays, the factor releases the remaining reserve net of the fee ($20,000 minus $4,000, or $16,000). The business’s total net proceeds are $180,000 plus $16,000, or $196,000, for a total financing cost of $4,000, or 2% of the invoice value, over 25 days. In the latter, the fee increases to $8,000, so $12,000 are released from the reserve, for a net of $192,000 and a cost of 4% of face value over 55 days.
Note: These figures are illustrative. Actual terms vary by factor and by client.
How the Factoring Process Works
While terms vary by provider, the factoring process generally follows a similar structure:
- Application and review: the business submits information about its accounts receivable, including an accounts receivable aging report and customer details.
- Credit review: approval is driven first by the creditworthiness of the account debtors. The factor also reviews the seller for concentration, invoice quality, dilutions, and operational risk, but the customer file carries more weight than it would in a conventional loan.
- Rate and advance rate determination: based on that review, along with transaction volume, concentration, and industry, the factor sets the discount rate and advance rate.
- Funding: once an account is approved and the invoices are submitted, the factor advances the agreed percentage of the total face value of those invoices.
- Collection and reserve release: the factor collects payment directly from the customer (notification factoring). Once payment is received, the remaining reserve is released, net of fees.
Because underwriting centers first on the customer’s credit rather than a full conventional underwrite of the seller, factoring can often be established more quickly than a traditional loan, though timelines vary by factor.
Where Factoring Tends to Fit
Better fit: B2B invoices to creditworthy account debtors, recurring billing, a diversified customer base, clean invoice documentation, and a need to convert receivables without adding funded debt.
Weaker fit: High dispute or return rates, heavy concentration in one or two customers, consumer receivables, or invoices that are not yet earned and billable.
Invoice factoring is one of several financing tools for business-to-business clients that need short-term working capital without adding debt. For companies with strong receivables and creditworthy customers, it can be a clean alternative to traditional debt. i95 Capital’s invoice factoring page covers facility size, advance ranges, and how the company places these programs.
