Invoice Financing: Stop Waiting 60 Days to Get Paid
By FortisFi Team

Your customers take 60 days to pay. Payroll doesn't wait. Invoice financing turns the invoices you already earned into cash now. Here's how it works.
The work is done. The money is not there.
Invoice financing exists for one reason: businesses that sell to other businesses finish the work weeks before they see the money. You delivered the materials, completed the job, and sent the invoice. Your customer now has 30, 60, or 90 days to pay, and that calendar does not care when your payroll runs or when your supplier expects a check.
That gap is not a sales problem. Your sales are fine. It is a timing problem, and timing problems have their own tools.
How does invoice financing actually work?
The mechanics are plain, and they run on an asset you already own: the unpaid invoice.
- You invoice as usual. Goods delivered or work completed, invoice sent on your normal terms.
- You submit the invoice to a funder. Instead of waiting out the terms, you assign or pledge that invoice.
- You receive an advance. Funders often advance 80% to 90% of the invoice's value up front, with the rest held in reserve.
- Your customer pays. When the invoice settles, the reserve is released to you, minus the funder's fee.
Structures vary. In some arrangements the funder collects from your customer directly; in others you collect as usual and settle with the funder. Either way, the invoice itself does the heavy lifting, which is why this product behaves differently from financing underwritten mainly on your own track record.
The collateral is the invoice. The credit that matters most is often your customer's, not yours.
Who does invoice financing fit?
It fits owners who sell to other businesses on terms and watch their cash sit in someone else's accounts payable department:
- Contractors billing general contractors and manufacturers shipping on net 30 or net 60
- Wholesalers and service firms whose revenue arrives by invoice, not at a register
- Growing businesses, where the pile of unpaid invoices grows right alongside sales
- Owners whose own credit is still building, but whose customers pay reliably
It does not fit businesses paid at the point of sale, since a retailer or restaurant has no invoices to advance against. It also struggles when customers pay late as a habit or dispute invoices often, because the funder is underwriting those payments too.
Invoice financing or a line of credit?
Both tools answer the same ache. The right pick depends on where your cash actually gets stuck.
A line of credit is underwritten on your business: your revenue, your credit, your time operating. You draw what you need and repay it, whatever the expense. It is the better tool when your cash needs are irregular and not tied to specific invoices.
Invoice financing is underwritten on the invoice. Because the funder is repaid from a specific customer's payment, the facility can grow as your invoicing grows, and an owner with a thinner file can still qualify on the strength of customers who pay on time.
Where invoice financing loses: cost follows time. The longer an invoice stays open, the more the advance costs you, so a customer who pays on day 75 quietly raises your price. There is also administration to carry, since each invoice moves through the funder. If your customers reliably pay inside two weeks, a line of credit is usually the cleaner tool. Our guide to what documents you need for a business loan covers the paperwork lenders ask for on either route.
What does the funder actually look at?
Owners are often surprised by this part. With invoice financing, the funder studies your customers at least as hard as it studies you.
- Customer creditworthiness. Established customers who pay their bills make your invoices easy to fund.
- Payment history. A customer who pays on day 45 of net 30 terms costs you more than one who pays on day 30.
- Concentration. If one customer makes up most of your receivables, the funder sees that risk too.
- Clean paperwork. Invoices that match purchase orders and proof of delivery move. Disputed or sloppy invoices stall.
Your own file still matters. At FortisFi, the starting paperwork is one application plus the last 4 months of business bank statements. From there, we review invoice financing alongside 18+ other products to find the structure that fits the way your business actually gets paid.
Key Takeaways
- Invoice financing advances cash against invoices you have already earned, so B2B owners stop floating their customers for 30 to 90 days.
- The funder underwrites your customers' credit and payment habits as much as yours; reliable payers make your invoices easier to fund.
- Choose a line of credit for irregular, general expenses; choose invoice financing when the cash gap lives in your receivables and grows with your sales.
