Build or Buy Embedded Invoice Financing: How to Decide In-House vs. a Provider
Building embedded invoice financing in-house means becoming a regulated lender: 12 to 18 months for the licence alone, plus a credit team, capital and collections before the first euro of revenue. Partnering ships the same feature in weeks with zero credit risk on your balance sheet. Here is the decision framework, the side-by-side comparison, and the cases where building still makes sense.
You have decided your platform needs embedded invoice financing. The open question is how to deliver it: build the credit operation in-house, or partner with a provider.
This guide gives you a decision framework and a verdict you can defend to a board.
Should you build embedded invoice financing in-house or partner with a provider?
For most platforms, the verdict is clear: partner. Partnering goes live in weeks. Building in-house takes 12 to 18 months, because you must first become a regulated lender with a lending license, a credit team, capital, and collections.
That time gap is the whole decision. A build turns your company into a lender. A partnership adds the feature with zero credit risk on your balance sheet.
So the real question is not build or buy. It is whether you want to own the machinery or own the experience. We unpack the same tension in our take on build or buy pay later.
Own the experience. Outsource the machinery. That is the shortcut most platforms take.
What is embedded invoice financing, and why are platforms adding it?
Embedded invoice financing lets suppliers get paid instantly inside your platform, while their buyers keep paying on their usual terms. The feature lives natively in your product. No redirect, no separate signup, no waiting.
Platforms add it because late payment is a structural problem, not a rare one. EU late payment data shows late payments remain an increasing problem in the EU, with more than half of companies reporting difficulties as a result in 2024.
The EU Payment Observatory also reports average payment periods exceeded 60 days in both B2B and G2B transactions as of 2025. That is cash your users wait on while they burn working capital they do not have.
The market is moving toward embedded solutions. Grand View Research frames the momentum: per its global embedded finance market report, the global embedded finance market size was estimated at USD 83.32 billion in 2023 and is projected to reach USD 588.49 billion by 2030, growing at a CAGR of 32.8% from 2024 to 2030.
Europe is part of that shift. McKinsey adds a regional lens: by 2030, the EF market could surpass €100 billion, per its work on embedded finance in Europe.
What does it actually take to build embedded invoice financing in-house?
To build embedded invoice financing in-house, you do not add a feature. You become a lender. That changes your company, your balance sheet, and your regulatory status.
Here is the real scope of building it yourself:
- Lending license: You obtain one first, which takes 12 to 18 months minimum in most European jurisdictions.
- Credit and risk team: You hire underwriters and analysts to build credit scoring and fraud detection, KYC/KYB, and invoice validation.
- Capital: You source and lock up capital, carrying receivables for 30 to 90 days before buyers repay.
- Collections and disputes: You run collections, dispute resolution, and reconciliation across every market you serve.
- Compliance: You manage regulatory compliance in each jurisdiction, and keep it current as rules change.
None of this is optional. All of it lands before your first euro of financing revenue.
That is the cost of building the machinery yourself.
What does partnering with a provider give you (and what do you give up)?
Partnering flips the model. The provider is the regulated lender. You keep the customer relationship and ship the feature fast.
Here is what a strong partner gives you:
- Speed: You go live in weeks through one API, not the 12 to 18 months a build demands.
- Zero credit risk: The provider is the regulated entity and offers protection against defaults, so risk stays off your balance sheet.
- Cross-border reach: B2B payments infrastructure covers 100+ countries and currencies through one integration, including SEPA, SWIFT, and FPS.
- New revenue: You earn a share of financing fees, turning invoice volume into a revenue stream.
A strong partner also underwrites the debtor, not the supplier. That means it can finance the long tail, like a €500 freelancer invoice, that traditional factors reject.
Aria works this way. It provides embedded financing for SaaS and assumes all credit, fraud, and dispute risk. Your platform carries zero credit risk and needs no lending license.
The revenue upside is real. Adyen and BCG frame a $185 billion opportunity, up 25% since 2022, and note SaaS platforms embedding financial products are set to amplify their revenues up to 3-4x.
Now the honest part. Partnering is not free of trade-offs. You share margin with the provider, and you cede some control over the credit product’s rules and limits.
For most platforms, that trade is worth it. You give up a slice of margin for speed, zero risk, and multi-market reach.
Build vs. buy: a side-by-side comparison
Put the three paths side by side. The differences are not subtle.
| Criteria | Build in-house | Bank partnership | Partner with Aria |
|---|---|---|---|
| Time-to-launch | 12–18 months | 3–6 months | Weeks |
| Licensing | You obtain a lending license | Bank’s license, imposed terms | No license needed; Aria is the regulated entity |
| Capital required | You source and lock up capital | Shared economics | None from your platform |
| Who carries credit risk | Your balance sheet | Shared | Aria; zero for you |
| Underwriting coverage | You build it | Capped approval rates, low granularity | Debtor-level; finances the long tail |
| Geographic coverage | Market by market | Bank’s footprint | 100+ countries and currencies |
| Collections/disputes | You run them | Partly shared | Aria handles them |
| Revenue impact | Revenue after 12–18 months | Shared economics | New revenue share, fast |
One column ships in weeks with zero risk. The other two do not.
How do you know which path is right for your platform?
The choice comes down to one question: is financing a product or a feature for you? Your answer sets the path.
Build embedded invoice financing in-house when these hold true:
- You sell financing as your core product: You are in the lending business, and you intend to own every part of it.
- You hold a license and capital: You already have, or will secure, the license and the balance sheet to lend.
- You value control over speed: You need full control over credit rules, and you can wait 12 to 18 months.
Partner with a provider when these hold true instead:
- You treat financing as a feature: You need it to ship fast and support the product your users already pay for.
- You want zero credit risk: You want the feature without a license, a credit team, or balance-sheet exposure.
- You need multiple markets: You serve buyers and suppliers across borders and currencies from day one.
The pattern is simple. Own the experience your users love. Outsource the machinery that makes it work.
What does partnering look like in practice?
Numbers make the case better than theory. Two Aria customers show what partnering for embedded invoice financing delivers.
Job&Talent’s results show the operational shift. The platform consolidated 20+ factoring partners into one. It cut financing lead time from 14 days to under 24 hours.
Work that took three full-time people now takes about one person a few hours a week. Job&Talent went live in the UK in three weeks, then added each new country in about a week.
UrbanChain’s 10x growth tells the second story. It unlocked £11M in financing and cut vendor payment times to about 15 hours. Revenue grew from £2.4M to £25M, a 10x jump.
No license. No credit team. No 18-month build.
How much does each option cost?
Cost is not just fees. The sharper question is time-to-revenue.
Building embedded invoice financing carries fixed, upfront, and recurring costs. You pay for a license, a risk team, capital, engineering, and ongoing compliance. All of it lands before your first euro of financing revenue.
Partnering shifts cost to a per-transaction model. You pay financing fees, with no upfront license and no locked capital. A revenue share offsets those fees as volume grows.
Build pays out in years. Partner pays out in weeks. Measure cost in time, not just in fees.
Frequently asked questions
The build-versus-partner decision raises a few recurring questions. Here are the direct answers.
Do we need a lending license to offer embedded invoice financing?
No, not if you partner. When you work with a provider like Aria, the provider is the regulated entity, so your platform needs no lending license.
How long does it take to launch embedded invoice financing?
Partnering goes live in weeks, while building in-house takes 12 to 18 months to secure a license alone. Job&Talent launched in the UK in three weeks and added each new country in about a week.
Who carries the credit risk if a buyer does not pay?
With Aria, the provider does. Aria purchases invoices outright and assumes all credit, fraud, and dispute risk, so your platform carries zero credit risk.
Will embedded financing hurt our customer relationships?
No. Suppliers get paid instantly inside your platform while buyers pay on their usual terms, which strengthens retention rather than straining it.
Can a provider finance small or new suppliers?
Yes. Aria underwrites the debtor, not the supplier, so it can finance the long tail that factors reject, including a €500 freelancer invoice.
How do we choose an embedded invoice financing provider?
Look for debtor-level underwriting, zero credit risk for your platform, and broad geographic coverage. The best providers ship in weeks and handle collections, disputes, and reconciliation for you.
