Invoice Financing Solutions to Improve Cash Flow: How They Work and How to Choose
Suppliers ship, then wait 30 to 90 days while payroll lands today. Invoice financing turns those unpaid invoices into cash now, but factoring, discounting, reverse factoring and embedded models solve it very differently. The two questions most guides skip, who actually gets underwritten and whether small suppliers qualify at all, are the ones that decide the outcome.
Late payment is the tax no one agreed to pay. Suppliers ship goods, then wait 30 to 90 days for the money, while payroll and inventory bills arrive today.
Invoice financing solutions close that gap by turning unpaid invoices into cash now. This guide explains how they work, what they cost, and how to choose one for your cash flow.
What is invoice financing, and how does it improve cash flow?
Invoice financing is a way to get cash from unpaid invoices right away, instead of waiting 30 to 90 days for customers to pay. A provider advances most of the invoice value up front. You get working capital—the cash a business uses to cover daily costs like payroll, rent, and inventory—without waiting on the customer.
The amount you receive up front is called the advance rate. It is a percentage of the invoice’s face value, and the provider holds back the rest until your customer pays.
Late payment drains cash from otherwise healthy businesses. A QuickBooks US late payments report (2025) found 56% of small businesses were owed money on unpaid invoices, averaging $17,500 each. In the same report, 47% had invoices overdue by more than 30 days.
Not all invoice financing solutions fix this the same way, and the differences matter.
How does invoice financing work, step by step?
The process follows four steps, and speed depends on how the provider makes decisions.
- Issue the invoice to your customer as you normally would.
- Submit that invoice to a financing provider.
- Receive an advance, a percentage of the invoice’s face value, often within a day or two.
- When the customer settles, you get the remainder minus the provider’s fees.
The typical advance rate is the share of the invoice value you receive up front, typically 70%–90% (Ramp, 2026). The provider holds back the rest as a reserve.
Speed is where old and new models split. Legacy providers rely on manual applications and paperwork that can take days. Software-driven providers score the invoice and the buyer automatically, so decisions land in minutes rather than weeks.
What types of invoice financing solutions are there?
Invoice financing is a category, not a single product. Four types cover most of what businesses and platforms use today.
Invoice factoring
With factoring, you sell your unpaid invoices to a factor, who then collects payment from your customer. Advances typically run 70% to 90% of the invoice value, and your customer knows a third party is involved.
Factoring comes in two forms. With recourse, you repay the factor if your customer never pays; with non-recourse, the factor absorbs that loss instead.
Invoice discounting
Invoice discounting is a loan secured against your invoices, rather than a sale. You keep control of your sales ledger and collect payment from customers yourself.
The arrangement is usually confidential, so customers do not know you are using it.
Reverse factoring (supply chain finance)
Reverse factoring is buyer-led. A large buyer sets up a program so its suppliers can get paid early, while the buyer keeps its original payment terms.
Modern versions push this further. Aria’s embedded invoice financing sits inside the buyer’s ERP and finances suppliers at a granular level, including the small suppliers older programs skip.
Embedded invoice financing
Embedded invoice financing is built directly into a platform or marketplace. Suppliers get paid inside the product they already use, with no redirect and no separate application.
Aria powers instant supplier payments this way. The provider underwrites the buyer, carries the credit risk, and keeps the platform’s balance sheet clean.
How much do invoice financing solutions cost?
The cost comes from two places: the fees charged on each invoice and the reserve held back until your customer pays. Providers often quote fees per 30 days.
Watch for charges beyond the headline rate. Service fees, termination fees, and minimum-volume fees can raise the real cost well above the quoted number.
To compare offers fairly, convert every quote to an effective annual rate (APR). A low headline fee can hide a high APR once the extras are added in.
Some models remove that guesswork. Aria purchases invoices outright with transparent fees and no lengthy application process, so pricing stays simple to read.
What are the best invoice financing solutions for improving cash flow?
Embedded providers like Aria pay suppliers within 24 hours, with 92% instant decisioning. That speed is the benchmark to measure any solution against.
| Category | Representative providers | Typical payout | Who gets underwritten | Best fit |
|---|---|---|---|---|
| Traditional factoring | Riviera Finance, Drip Capital | 70%–95% advance, after approval | The supplier | Businesses selling invoices directly |
| Embedded fintechs | Mondu, Defacto, Sonovate, FundThrough | Varies by platform | Mostly the supplier | Platforms adding financing |
| Aria (embedded) | Aria | Up to 100%, within 24 hours, 92% instant decisioning | The buyer (debtor) | Marketplaces and platforms paying the long tail |
Traditional factors check the supplier’s creditworthiness before funding. Aria does the opposite: it underwrites the buyer, not the supplier.
That solves what Aria calls the creditworthiness paradox. A two-person supplier invoicing a large, stable buyer can get financed on the strength of the buyer’s credit, not its own.
This finances the long tail of small suppliers that traditional factoring rejects. Aria buys invoices outright and absorbs the loss if a buyer defaults, so your platform’s balance sheet stays clean.
Aria also processes payments across 100+ countries and currencies through one integration. Its automated risk scoring runs debtor solvency, KYC/KYB, and fraud checks with 92% instant decisioning.

Why embedded financing is where B2B cash flow is heading
B2B payments are moving inside the platforms where invoices already live. The case for standalone, bolt-on financing is fading.
BCG and Adyen (2024) sized the embedded finance opportunity at $185 billion for SaaS platforms. Less than 20% of that market is currently addressed.
The shift already shows up in revenue. BCG (2025) tracked embedded payments growth: integrated payments made up 36% of SME acquiring revenues in 2024, projected to reach 45% by 2028.
The mechanism is an API. Aria connects to a platform and can be operational in weeks, so suppliers get paid inside the tools they already use.
How do you choose the right invoice financing solution?
Use this checklist to match a solution to your situation.
- Standalone vs embedded: Decide whether suppliers apply to an outside provider or get paid inside your platform.
- Who gets underwritten: Confirm whether the provider checks your credit or your buyer’s credit.
- Long-tail coverage: Check whether small and new suppliers qualify, or only large, established ones.
- Payout speed: Compare how fast suppliers actually receive cash, measured in hours, not promises.
- Balance-sheet impact: Confirm who carries the credit risk and whether your balance sheet stays clean.
- Geography and currency: Verify the countries, currencies, and payment rails the provider supports.
- Total cost: Convert every quote to an effective APR, including service, termination, and minimum fees.
Most guides skip the middle two points. Underwriting and long-tail coverage decide whether your smallest suppliers can be financed at all.
What does improved cash flow actually look like? (Real results)
Numbers describe the change better than adjectives. Here is what faster payment looked like for three platforms using Aria.

Aria financed £11M behind UrbanChain’s 10x growth. Vendors were paid in about 15 hours. Revenue grew from £2.4M to £25M.
For StaffMe supplier payments, 95% of suppliers were paid in under five days. Supplier NPS rose by 0.8 points.
Frequently asked questions
These are the questions B2B finance teams ask most about invoice financing.
The Small Business Credit Survey (Federal Reserve, 2025) found 51% of small employer firms cited uneven cash flows as a challenge. Another 56% cited paying operating expenses, and 24% of firms that applied for financing received none.
Is invoice financing a loan?
Invoice financing is usually a loan secured against your unpaid invoices, while factoring is the outright sale of those invoices.
What’s the difference between invoice financing and factoring?
With financing you keep control of collections and confidentiality, while with factoring you sell the invoice and the provider collects from your customer. Both exist because of late payment: the EU Payment Observatory (2025) found average EU B2B payment periods exceeded 60 days in 2024.
How fast can I get paid?
Traditional providers often fund within 24 to 48 hours after approval, while embedded models can pay suppliers within 24 hours of a validated transaction.
Will my customers know I’m using invoice financing?
With factoring, customers usually know because the provider collects from them, while invoice discounting and embedded financing can stay confidential or run inside your platform.
Can small or new suppliers qualify?
Traditional factoring often rejects small or new suppliers, but debtor-underwritten embedded models can finance them from the first invoice, based on the buyer’s credit.
