Embedded finance has become one of the most overused terms in B2B SaaS — right up there with "seamless" and "best-in-class." But the underlying shift it describes is real, and for vertical SaaS companies and B2B fintechs, it's increasingly a competitive moat, not just a nice-to-have.

This post breaks down what embedded finance actually means, which categories matter for B2B platforms, and which vendors are building the infrastructure that powers it.

The short definition

Embedded finance is the integration of financial services — payments, banking, lending, insurance, compliance — directly into non-financial products and platforms.

Instead of sending users to a bank or a standalone financial product, you deliver those services from inside your own app. Under the hood, you're using API-based infrastructure from a specialized provider. The financial experience is yours. The heavy lifting — licensing, compliance, banking relationships — belongs to someone else.

Why it matters for B2B SaaS and vertical SaaS

For consumer fintech, embedded finance mostly means slapping a debit card on a neobank app. For B2B platforms and vertical SaaS, the story is more interesting.

Your customers already trust your platform for their core workflow — whether that's construction project management, restaurant operations, HR, or freight logistics. Adding financial services inside that workflow creates stickiness, new revenue streams, and a fundamentally harder-to-replace product.

The companies that figured this out early are hard to compete with. Toast owns restaurant payments. Procore is adding financial features for contractors. ServiceTitan is building spend management for home services businesses. They're not banks. They didn't need to become banks. They just needed the right infrastructure partners.

The main categories

The Open Banking Tracker currently tracks 107+ embedded finance providers across 12+ categories. Here are the ones most relevant for B2B fintech and vertical SaaS:

Banking-as-a-Service (BaaS)

BaaS providers give you the infrastructure to offer bank accounts, deposits, and regulated financial products without holding a banking license. They sit between you and a licensed sponsor bank.

Relevant vendors: Unit, Stripe Treasury, Treasury Prime, Swan, Griffin, Column, Synctera

Best fit: fintechs building neobank features, platforms that want to hold customer funds, or SaaS companies adding business accounts to their offering.

Card Issuing

Card issuing platforms let you launch virtual or physical payment cards under your own brand, with real-time controls over spending limits, merchant restrictions, and authorization rules.

Relevant vendors: Marqeta, Lithic, Highnote, Thredd, i2c

Best fit: expense management tools, fleet software, travel platforms, and any SaaS that wants to give customers a spend card tied to their workflow.

Embedded Lending

Working capital, B2B BNPL, invoice financing, and revenue-based financing — delivered through your platform rather than a third-party lender.

Relevant vendors: Kanmon (B2B SaaS), Parafin (marketplaces), Defacto (B2B BNPL, Europe), Finmid (B2B BNPL), Liberis (merchant financing), Pipe (revenue-based)

Best fit: vertical SaaS with SMB customers who have cash flow timing problems. This is arguably the highest-value embedded finance use case for B2B — your platform already sees the data that determines creditworthiness.

Embedded Payments

Payment facilitation, merchant services, and acquiring — so your users can accept payments inside your platform.

Relevant vendors: Adyen, Rainforest Pay, Forward, Finix, GoCardless, Mollie Connect

Best fit: any vertical SaaS where transactions happen inside the product. Think field service software, booking platforms, marketplace operators.

AP/AR Automation

Embedded accounts payable and receivable — invoicing, bill pay, and collections without leaving your platform.

Relevant vendors: Monite (vertical SaaS-focused), Melio (embedded bill pay), Mercoa (AP/AR for SaaS), BILL

Best fit: accounting platforms, ERP add-ons, procurement software, or any B2B SaaS where buyers and suppliers interact.

Embedded Payroll

Full payroll processing and compliance through your platform. Particularly valuable for HR platforms, POS systems, and workforce management tools.

Relevant vendors: Gusto Embedded, Check, Salsa, Remote, Clair (earned wage access)

Best fit: HR platforms, staffing software, construction or field service apps with hourly workers.

Embedded Expenses

Corporate card and spend management infrastructure you can white-label into your product.

Relevant vendors: Pleo Embedded, Cardlay, Findity, Fidel API

Best fit: ERP and finance platforms, travel and expense tools, accounting software with SMB users.

Compliance and KYC/KYB

Identity verification, AML screening, fraud detection, and decisioning — so you can onboard financial customers without building that infrastructure yourself.

Relevant vendors: Alloy, Persona, Veriff, Sardine, ComplyAdvantage, Socure, Fourthline

Best fit: anyone adding financial services to their platform. You can't skip this category.

FX and Cross-Border Payments

Multi-currency accounts and cross-border payment infrastructure for platforms with international users or suppliers.

Relevant vendors: Airwallex, Currencycloud (Visa), Nium, Convera, Okoora

Best fit: travel tech, global marketplaces, international B2B platforms, companies with multinational payouts.

Embedded Insurance

Coverage bundled into the point of transaction — not a separate policy the user has to go get.

Relevant vendors: Cover Genius (travel, e-commerce), Hokodo (B2B BNPL + trade credit), Zego (fleet/logistics), Authentic

Best fit: travel platforms, logistics software, B2B marketplaces with credit exposure.

Vertical SaaS examples worth watching

A few companies on the OBT directory that show where this is heading:

Toast — started as restaurant POS, now handles payments, payroll, and working capital for restaurants. The financial services are part of what makes switching costs so high.

Procore — construction management software with embedded payments and financial workflows for contractors and subcontractors.

ServiceTitan — home services SaaS (HVAC, plumbing) with embedded payments, financing, and spend management.

These aren't financial companies. They're software companies with distribution, workflow lock-in, and now financial infrastructure built in. That combination is the real moat.

Where Apideck fits

Apideck sits one layer up. We're not an embedded finance provider — we're the integration layer that connects platforms to their accounting and ERP data, which is often the foundation that makes embedded finance work.

Before you can offer embedded lending, you need to see your customer's P&L. Before you can automate AP/AR, you need to sync with their accounting system. Before you can build bank feeds, you need a reliable connection to QuickBooks, Xero, or NetSuite.

That's what Apideck does — a single unified API connecting to 30+ accounting and ERP platforms via the Apideck ERP API, so you don't have to build and maintain those integrations yourself.

Wrapping up

Embedded finance isn't one thing. It's a set of infrastructure categories — banking, cards, lending, payments, payroll, compliance, insurance — that B2B SaaS companies can now layer into their products without becoming financial institutions.

The OBT directory tracks 107+ providers across these categories. If you're evaluating which ones to use, the decision usually comes down to: what's the core financial action your users need to take inside your product, and which provider has the best API, compliance coverage, and bank partner for your region?

Start there.
