Invoice Factoring Explained — Including What Others Hide
Cash flow, not profit, is the number one reason companies shut down. Research from U.S. Bank shows that 82% of failed businesses point to cash flow problems as the leading cause. You can look profitable on paper, but if customers take months to pay, your money is stuck, and your business feels the squeeze.
That’s where invoice factoring comes in. It gives you access to working capital, predictable cash flow, and control over timing.
But here’s the problem: most of the information online about invoice factoring is repetitive and designed more to market the factoring companies than to guide you. Articles are cloned from one website to another, built to rank on Google, or quoted by tools like ChatGPT. They’re not written to help you; they’re written to serve the factoring companies. What you read usually reflects what factors want you to hear, not what you actually need to know.
What Invoice Factoring is, and What Matters
Invoice factoring lets you turn unpaid B2B invoices into fast cash by typically advancing 70–90% upfront, paying you the rest when customers pay, with typical costs of 1–5% every 30 days.
The Everyday Invoice Factoring Process
Here’s a typical funding process, including some details that are rarely explained:
- Invoice Submission:You submit invoices in what is usually called an “assignment schedule” to the factor, typically through a portal (but some still use email submissions).
- Verification: The factor reviews and verifies the invoices, along with any necessary documentation related to your customers, to confirm their validity.
- Advance Payment: Once approved, typically on the next business day, the factor wires your pre-agreed advance, usually 70% to 90% of the invoice face value.
- Customer Payments:Your customers send payments to a lockbox that the factor controls, under your business name.
- Funds Release: When the customer payment is received, the money is deposited into your reserve account, and it is typically released to you weekly, minus fees.
Insider Insight
Reserves are the hidden piece that few explain. They are the holdback that protects the factor against disputes or deductions. For you, it means you don't see the balance at the time it is collected, so your planning must include reserve timing.
When is Factoring a Good Choice for Your Business?
Here are some specific cases when you may benefit from invoice factoring:
- Your customers pay slowly, and you need a reliable cash flow every day.
- You don’t qualify or have limited access to traditional bank financing.
- Your gross margins can absorb the cost, and you still make money.
- You may benefit from help tracking receivables and collections.
- You can take advantage of customer credit checks before you offer terms.
- Your business is growing fast, and you need more capital than your bank limit allows.

What Most Factoring Websites Won't Tell You
The information found online on many factoring websites and intermediaries’ lists can be misleading. Behind the ads and recommendations, there are costs, contracts, and payment rules that can help or hurt your business. Most websites skip details that are crucial for you to know before you agree to anything.
- There are hundreds of factoring companies. The same few names appear online because of ads, partnerships, and broker networks, not because they’re necessarily the best fit. Not-so-know or specialized providers may offer better terms for your business’s special situation.
- Rates are tricky. An advertised rate, such as 0.5% or 1%, can be misleading if you don’t understand the time frame and other conditions attached to it. There are various types of rates that contribute to the final cost, including flat rates for fixed periods, variable rates, and deals that may incorporate additional fees, all of which can increase your total cost. Many factors influence the rate at which your business can secure, and it’s crucial not to be deceived by the small numbers often published. In reality, very few companies qualify for those promotional rates.
- Contracts, not proposals, define the final relationship: While proposals typically present advance rates, factoring fees, and minimum volume requirements, they often do not encompass the full scope of your obligations. Once you accept a proposal, you’ll be required to sign a contract that includes numerous other conditions, such as termination fees, reserve requirements, and extra fees, that can significantly impact your factoring relationship and overall costs.
- Reserves shape real cash flow. Typically, the factoring company will require that all customer payments be submitted to a designated lockbox, regardless of whether those invoices have been factored or not. This means that you’ll have to wait until the reserve release day to access your funds.
- Your clients may know. Even when reputable factoring companies manage communications with your clients carefully, there are instances where it becomes clear that another party is involved. For example, documents like Notices of Assignment and occasional outreach can signal to your clients that they are dealing with a factor.
- It doesn’t have to be forever. Many firms use factoring only until bank credit becomes available or their cash flow stabilizes.
Insider Insight
Do not confuse visibility and big website recommendations with the quality of service. The first names you see on Google and in "top 10" lists often pay for their prominent placement, whether through advertisements, partnership agreements, or other marketing efforts. There are several smaller or specialized factoring companies that are not so popular and may offer better service, more flexible terms, or lower costs, and can be a better fit for your unique business needs.
