How Factoring Actually Works, Step by Step (From Invoice to Cash)

You did the work, you sent the invoice, and now you’re just… waiting.

The job’s done. The client is happy. But your payment terms are net 60, so that money won’t hit your account for two months. Meanwhile, payroll is Friday, your vendors want paying, and your cash is stuck inside an invoice you can’t spend.

You’ve heard “factoring” can turn that invoice into cash now. But you’re not totally sure how it works, or what it really costs, or what the catch is.

Let’s clear it up. Here’s exactly how factoring works, step by step, from the moment you send an invoice to the moment the cash lands, so you know precisely what you’re signing up for.

What factoring actually is

Let’s start with the simple version, because the word sounds more complicated than the thing.

Factoring is selling your unpaid invoice to a financing company for cash today. Instead of waiting 30, 60, or 90 days for your customer to pay, you hand the invoice to a factor, and they give you most of the money right away.

Then, when your customer eventually pays, they pay the factoring company, not you. The factor collects the full invoice, keeps a small fee, and sends you the rest.

That’s the whole idea. You’re not borrowing money and taking on debt. You’re selling an asset, the invoice, to get your cash sooner. The value was always yours, factoring just lets you access it now instead of later.

Why this even exists: the net-terms problem

Factoring solves one specific, painful problem that a lot of businesses face. It’s worth naming, because if this is your problem, factoring fits it perfectly.

When you sell to other businesses, especially big ones, you usually get paid on net terms. Net 30 is standard. Sell into big-box stores or large retailers and it often stretches to net 60 or net 90.

Here’s what that does to you. You deliver the goods, you send the invoice, and then you wait, while your cash flow slowly drains. You’re still paying employees, still paying vendors, still covering all your operating costs, all while your money sits locked in unpaid invoices.

And it gets worse the more you grow. The more you sell on net terms, the more of your own cash gets tied up waiting to be paid. Success starts to squeeze you. Factoring exists to break that cycle, turning the invoices into cash so your growth doesn’t starve your cash flow.

The step-by-step: from invoice to cash

Here’s exactly how a factoring transaction flows, start to finish.

Step 1: You do the work and invoice your customer. Nothing changes here. You deliver your product or service and send the invoice on your normal net terms, just like always.

Step 2: You submit the invoice to the factor. Instead of filing the invoice away and waiting, you send it to the factoring company. They verify it’s a real, valid invoice to a creditworthy customer.

Step 3: The factor advances you most of the money, fast. Once approved, the factoring company advances you a large chunk of the invoice’s value up front, often the great majority of it, typically within a day or two. That cash is in your account while your customer still has weeks to pay.

Step 4: Your customer pays the factor. When the invoice comes due, your customer sends their payment to the factoring company instead of to you. This is the part that surprises some owners, so it’s worth knowing going in: your customer is aware of the arrangement and pays the factor directly.

Step 5: The factor sends you the rest, minus their fee. After collecting the full invoice from your customer, the factor releases the remaining balance to you and keeps their fee for the service.

That’s the full loop. Invoice out, cash in fast, customer pays the factor, you get the remainder. The whole point is that you got most of your money in a couple of days instead of waiting two or three months.

What it costs

Factoring isn’t free, so let’s talk plainly about the cost, because knowing it helps you decide if the trade is worth it.

The factor charges a fee for advancing your cash and handling the collection. On a factoring arrangement, that cost can start at less than 1% per month of the invoice value. The exact fee depends on things like the size of the invoice, how creditworthy your customer is, and how long the invoice takes to get paid.

So the real question is simple. Is paying a small fee to get your cash 60 or 90 days early worth it? For a business that needs the money now to make payroll, buy materials, or take the next job, it very often is. The fee is small next to the value of having your cash working instead of frozen.

Run your own quick math: what does the factoring fee cost you, versus what you can do with that cash two months sooner? If having the money now keeps your business running smoothly or lets you take on more work, the fee usually pays for itself.

Factoring vs. borrowing against your invoices

Here’s a distinction that trips people up, and it’s worth understanding, because they sound similar but work differently.

Factoring means you sell the invoice. The factor takes over collecting it, and your customer pays them directly.

The other option, accounts receivable financing, means you borrow against your invoices instead of selling them. You get a line of credit based on your receivables, but you still own the invoices and your customer still pays you. Your customer never even knows.

With AR financing, lenders often advance up to 80 to 90% of your receivables, at rates that can start around prime plus one because the invoices secure the line. If you have $5 million in receivables owed to you, that could translate into a $4 million-plus line of credit you draw on as needed.

Which is better depends on your situation. Factoring is simple and hands off the collection work. AR financing keeps you in control of your customer relationships and can be very cost-effective. The right choice comes down to whether you’d rather sell the invoices or borrow against them, and a good financing partner can lay both options side by side.

When factoring is a great fit

Factoring isn’t for everyone, but for the right business it’s a genuinely powerful tool. A few signs it fits well.

You’re selling to solid, creditworthy customers. Because the factor is really counting on your customer to pay, factoring works best when you invoice reliable businesses. If you’re selling to a large, well-known company that always pays its bills, that strengthens your position, and here’s a bonus: your own personal credit matters far less on this kind of deal, because it’s built on the customer’s ability to pay, not yours.

You’re stuck waiting on long net terms. If your cash is constantly tied up in net 30, 60, or 90 invoices, factoring frees it up so you can operate and grow.

You want cash fast without taking on traditional debt. Because you’re selling an asset rather than borrowing, factoring gets you money quickly, often in a day or two, without a conventional loan on your books.

If those describe you, factoring can turn your slow-paying invoices into the steady cash flow your business needs to keep moving.

From waiting to paid

Factoring takes the most frustrating part of running a business, doing the work and then waiting months to get paid, and largely solves it. You send the invoice, hand it to a factor, and get most of your cash in a day or two instead of 60 or 90 days later. Your customer pays the factor, you get the rest minus a small fee, and your cash keeps flowing the whole time.

It’s not the only way to unlock your invoices, AR financing lets you borrow against them instead of selling them, and the right choice depends on your situation. But for a business drowning in net terms and hungry for cash now, factoring is a clean, fast solution.

Since 2022, QualiFi has facilitated over $355 million in financing across a network of 75+ lenders, including invoice factoring with rates starting at less than 1% per month, plus accounts receivable financing up to a 90% advance rate for owners who’d rather borrow against their invoices than sell them. Funding runs from $5,000 to $75 million across all credit profiles, and the right structure gets your cash working instead of waiting.

You already earned the money. Factoring just lets you use it now. If slow-paying invoices are choking your cash flow, this is how you turn them back into cash you can actually put to work.
