What Is Embedded Finance? Use Cases, Models, and Architecture

What embedded finance means in practical product terms

Let’s look closer at any marketplace. Its main idea is to connect buyers and sellers. But it can’t be done without financial operations. The system needs to accept payments, calculate fees, determine net payouts, execute transfers, process refunds, and track overall transaction status.

Building a financial block from scratch is costly and time-consuming. That’s why embedded finance is crucial in these situations. Financial operations may be handled by external financial partners, while users get a complete service inside the marketplace. 

Though it’s worth mentioning that embedded finance development services are more than just adding a financial provider. It’s crucial to determine how financial processes would be linked to the product business rules, user roles, data, and other workflows.

Why it is different from just “adding payments”

To add payments means giving the end user a way to pay for the product or service. Embedded finance goes for a broader set of functions. It covers payments, accounts, balances, payouts, financing, and other operations that become part of the core product and its business scenarios.

At the same time, the platform is not required to build the financial infrastructure on its own. An external financial partner can be responsible for accounts, transaction execution, payouts, compliance checks, and other financial operations. The platform integrates these capabilities into its processes. It may determine when a financial scenario is triggered, what actions are available to the user, how its result affects the main workflow, and what data must be returned to the product. 

That’s why embedded finance is a way to integrate financial services inside the product’s logic, keeping the financial infrastructure on the separate provider’s side.

Where users actually encounter embedded finance

Most users interact with embedded finance daily even without understanding it.

• Marketplaces: sellers connect bank accounts, track balances, and receive payouts inside the platform.
• HR and payroll products: employees access payroll-related payments, benefits, or earned wage services through an existing workspace.
• B2B software: companies pay invoices or suppliers without switching to a separate banking interface.
• Travel platforms: customers add insurance during booking.
• E-commerce products: buyers select financing or instalment payments at checkout.

These examples demonstrate the main idea behind embedded finance. Financial function is integrated seamlessly into the customer journey, without the need to interact with a separate financial organization.

Common types of embedded finance

There are several core models of embedded finance. Depending on exactly where financial operations occur, these models can be used independently or combined within a single product.

Payments

Embedded payments allow users to pay for goods, services, subscriptions, or invoices directly within the platform.

For a simple SaaS product, it may be implemented as a simple checkout. For a marketplace, the logic would be more complex. The platform can accept payments from buyers, deduct its commission, calculate the seller's net amount, and execute the payout.

Users may see it as a seamless process, though from a system standpoint it requires multiple operations that should be properly handled and processed.

Accounts, wallets, and cards

For some products, merely accepting individual payments is not enough; they must support balances or account functionality directly within the platform. A marketplace, for example, might display a seller's total earnings, pending funds, and available payout balance.

UI displays it as a simple sequence of digits, but under the hood it’s much more complicated. The system has to understand which specific transactions comprise this balance, why its value changed, and which funds are actually available to the user.

That’s why wallets и accounts require a more thought-through financial model than a simple payment flow.

Lending and BNPL

Lending and BNPL models let platforms offer financing directly within the user journey, without redirecting clients to a separate website.

For example, a marketplace can provide functionality to split the purchase into several separate payments, while the external financial partner handles application underwriting, funding, and subsequent repayment. 

The platform integrates the financing option into checkout and its order workflow, while the lending partner handles the responsibilities assigned to it, such as underwriting, funding, or repayment processing. 

Insurance

Embedded insurance operates on the same principle. 

A travel platform can offer insurance at the time of booking, while an automotive marketplace can provide appropriate coverage during a vehicle purchase or lease. 

Users no longer need to search for an insurance product independently or repeat the entire process. Instead, insurance becomes an inherent part of the initial customer journey.

Payouts and treasury workflows

Payouts and treasury workflows help platforms manage the movement of funds once money enters the system. 

A marketplace can automatically distribute funds among sellers, deduct commissions, and route payouts to their bank accounts without building its own payment infrastructure. While the financial partner executes the actual monetary operations, the platform manages the rules and scenarios that trigger these transactions and reflect them within the product.

Embedded finance vs banking-as-a-service vs open banking

Embedded finance, Banking-as-a-Service, and Open Banking may work together, but they describe different parts of the financial ecosystem:

• Open Banking provides consent-based access to bank-account data and payment-initiation capabilities.
• Banking-as-a-Service provides banking capabilities—such as accounts, cards, or payments—through licensed institutions and technology partners.
• Embedded finance incorporates a financial capability into the workflow and business model of another product.

These models can be used together, but none is mandatory in every product. An embedded-finance platform may use BaaS for accounts and payments, Open Banking for account verification or pay-by-bank flows, or specialized payment, lending, and insurance providers.

Connecting to financial infrastructure is not enough on its own. Embedded finance begins when the financial capability becomes part of the product’s native workflow, business rules, and operating model.

Where APIs fit

API can be viewed as a mechanism that allows those layers to interact.

Open Banking API can grant access to account data or payment initiation. BaaS API can empower a company to offer accounts, cards, or payments through a banking partner. Embedded finance leverages these APIs to weave third-party financial capabilities directly into its own product workflow.

The API itself doesn’t determine how the financial infrastructure would work. The API may create an account, but the architectural logic determines when this account is created, who the account holder is, how statuses are tracked, what actions are permitted, and so on.

In embedded finance, API integration is only a part of the structure. The project requires custom business rules, financial workflows, transaction state handling, and data exchange between internal and external systems.

Core architecture behind embedded finance

Embedded-finance architecture depends on the capabilities being added, target markets, provider model, transaction volume, and operational responsibilities. Many products still require the same core components.

Most complex solutions have similar components. 

Provider layer

The provider layer may include banks, payment processors, BaaS platforms, lenders, insurers, identity providers, and other financial partners. They handle the actual execution of individual operations, processing payments, moving funds, underwriting financial products, or managing core account functionality.

And it’s crucial not to turn an external provider into a single source of truth for the entire product logic. For instance, a provider might return a pending status, fire a webhook, or temporarily time out. The platform needs to understand exactly what this event means for its own workflow and trigger the next step accordingly. This is why transaction states, webhooks, retries, idempotency, and error handling must be baked into the integration layer from day one.

Ledger / system of record

If a product handles balances, wallets, or multi-step financial operations, it requires a robust source of financial truth, a system of record.

The system must make balance changes traceable to the transactions that created them and distinguish between pending, available, reserved, and paid-out funds.

It’s especially important in systems where money goes through multiple stages. Funds can be pending, available, reserved, or already dispatched for payout. For systems of such complexity, it’s not enough to handle funds with a single ‘balance’ entity to give end users detailed explanations of their transactions. 

That said, a ledger doesn't have to be a full-scale core banking system. Its structure and depth depend entirely on the business model and the exact share of financial liability the product takes on.

Orchestration

Orchestration brings separate financial operations into a single unified workflow.

Let's look at a marketplace transaction. First, the user pays for the order. The system then calculates the marketplace fee, logs the seller's earnings, waits for the required status confirmation, and finally triggers the payout. No single provider necessarily owns the complete product workflow. The orchestration layer connects provider events with internal business rules and determines which action should happen next.

Reconciliation

Even when every integration performs smoothly, data between the systems can vary. As an example, the internal system flags a payout as complete while the provider still reports it as pending.

For that sort of issue, reconciliation is crucial. It regularly cross-references financial records and flags the discrepancies. Reconciliation for embedded finance acts as a part of operational reliability. The more providers, payment flows, and transaction types a product uses, the more critical it becomes to have a streamlined process for reconciliation and exception handling. 

Compliance and onboarding

Depending on the system, compliance and onboarding may include customer onboarding, identity verification, KYC/KYB, transaction monitoring, and other regulatory requirements.

In a proper project, those nuances are accounted for at the design stage. If compliance is added on top of the main workflow, the necessary checks cannot be smoothly integrated without rewriting the user experience or redesigning the core architecture.

The applicable requirements should be validated with the client’s legal, risk, compliance, and provider teams.

When companies should build embedded finance into a product

Embedded finance is a worthy addition if money is already a part of a business process, and adding a separate financial service complicates the user experience.

Before adding payments, accounts, lending, or payouts, teams should ask:

• What measurable user or operational problem will the capability solve?
• Where does money move within the existing workflow?
• Which users and roles participate?
• Will the capability improve conversion, retention, revenue, or operational efficiency?
• Which responsibilities should remain with external providers?

SaaS

For SaaS, financial functions may become a natural extension of the existing product. 

For example, an accounting platform might add payments and expense management, or financial accounts. HR software may include payroll-related financial workflows.

The platform already knows its user. What business they run, and theactionsn they take. Embedded finance can use this data to make the workflow smoother.

Marketplaces

Once the platform connects buyers and sellers, money starts moving between multiple parties. A marketplace can accept payments, hold commissions, manage seller balances, and handle payouts. 

Over time, extra features might pop up, like seller financing, insurance, business accounts, or other financial products. The challenge is that a single user action can affect several financial workflows at once. The marketplace needs to decide early on where the financial state lives, how transaction statuses update, and how the system reconciles its own records with provider data.

HR / payroll / benefits

HR and payroll platforms are working with data on employers, employees, payroll, and benefits. 

Depending on the product, financial functions may include payroll-related payments, employee accounts, earned wage access, insurance, and other services.

Permissions, compliance,e and correct data segmentation are especially important. Embedded finance needs to fit right into existing HR workflows without creating a complicated process for employers and employees.

B2B platforms

For B2B platforms, financial transactions are often deeply tied to core business operations. Here, embedded finance can eliminate manual tasks across different systems. 

However, B2B products usually come with more complex approval workflows, roles, and financial controls. This makes it vital to design the financial logic right alongside the core product, rather than treating it as an afterthought.

What to talk through before implementation

Before selecting a provider or implementing an integration, teams need to define several decisions that directly affect the product architecture and operating model. 

Partner model

The main question is: who is actually providing the financial service, and what liability do they take on?

This can be a bank, payment processor, BaaS provider, lender, insurer, or a mix of several partners. 

It’s crucial to determine who handles the regulated activity, who runs the required checks, who is responsible for transaction processing, and what data gets sent back to the platform. 

Picking a partner goes hand-in-hand with your architecture. One provider might be a great fit for payments but fall short on account functionality or specific geographic coverage.

What to build and what to integrate

Teams should decide which capabilities belong inside the product and which should remain with external providers. Regulated account infrastructure, payment rails, underwriting, or identity verification may come from partners. Product-specific rules, permissions, transaction states, orchestration, reporting, and exception handling often need to remain under the platform’s control.

The goal is not to build every financial component internally, but to avoid outsourcing business-critical product logic to a disconnected set of providers.

Geography and regulation

The countries and regions where the product will launch directly impact embedded finance. 

Not all providers support the same markets, payment rails, currencies, or financial products. On top of that, requirements for KYC/KYB, onboarding, transaction monitoring, and other compliance steps vary by jurisdiction. This is why you need to lock down your geography and regulatory strategy before picking partners and designing your architecture. 

Financial operations do not end with a successful API response. Products must also be prepared for delayed events, provider outages, duplicate requests, inconsistent statuses, and manual exceptions.

Operational risk

Every product has to be ready for things to go wrong. Финансовая операция не заканчивается успешным API response.

A transaction can get stuck in a pending state. A request can be retried. Data across different systems can temporarily get out of sync. 

This is why you need to figure out exactly how your system will handle failures, retries, duplicate events, unexpected statuses, and reconciliation issues well before you start implementation. The more money moves through your product, the less room you have for scenarios where your team cannot explain what happened to a specific transaction.

Ownership of data and money movement

Finally, you need to clearly define which system serves as the source of truth for each data type and who controls the movement of money. 

A provider might be the system of record for a specific external transaction, while your product holds its own financial states and business context. You also need to pin down where balances are calculated, where transaction states are tracked, who triggers payouts, and how internal data is reconciled with provider records. 

Without this setup, your financial logic quickly devolves into a tangle of disconnected API calls that are tough to control and maintain.

How Celadonsoft approaches embedded finance delivery

Celadonsoft views embedded finance primarily as a challenge of architecture and financial workflows, rather than a mere bundle of individual API integrations. Before development even begins, we dissect which financial transactions the product actually needs, who the stakeholders are, what states a transaction can pass through, and which systems must exchange data. 

Next, we define the integration model, determining which functions stay with external providers and what logic must live inside the product itself. This keeps business-critical rules from getting buried inside multiple third-party services. We pay special attention to balances, transaction states, payouts, reconciliation, and exception handling. For an embedded-finance product, successfully processing a transaction is not enough; the platform must also maintain a clear and explainable financial state at every step.

We also account for onboarding, permissions, geography, operational workflows, and compliance-related requirements identified with the client’s legal, risk, and provider teams. This ties the user journey directly to the real-world constraints of financial infrastructure. As a result, embedded finance is treated not as a standalone payment feature, but as a core financial layer within the existing product, complete with clear boundaries of responsibility, tight integrations, and full control over data and money movement. 

If embedded finance grows into a larger fintech product strategy, this approach can scale into comprehensive fintech platform engineering, including building core financial logic, integrating banking infrastructure, and setting up connected operational workflows.

As an official Priority Passport engineering partner, Celadonsoft has hands-on experience with product-level capabilities across accounts and balances, banking and treasury integrations, fund movement, payment workflows, reconciliation, and operational tooling. We apply this implementation experience when designing provider-neutral embedded-finance architecture for other products.
