When people search for banking as a service, BaaS, or baas banking, they're usually looking for one of two things: a clear definition of what it is, or a concrete list of providers they can evaluate. This guide covers both.
What is Banking as a Service (BaaS) / BaaS Banking?
Banking as a Service (BaaS), often called BaaS banking, is a model where licensed banks expose their core banking infrastructure—accounts, payments, cards, lending, and compliance—via APIs so that non-bank companies can embed financial products directly into their own platforms. The bank holds the license and handles regulatory requirements; the BaaS client builds the customer-facing experience.
In practice, this means a fintech, marketplace, or vertical SaaS company can offer branded checking accounts, debit cards, or lending—without obtaining a banking charter—by integrating with a BaaS provider that connects them to a licensed bank. The bank provides FDIC insurance (US), safeguarding (UK), or equivalent; the BaaS platform provides the API layer and often compliance tooling.
What Do Banking as a Service Providers Do?
BaaS providers typically offer some or all of the following:
- Deposit accounts — FDIC-insured (US) or safeguarded (UK/EU) accounts via API
- Card issuing — Virtual and physical debit/credit cards with real-time controls
- Payments — ACH, wire, SEPA, instant payments, and book transfers
- Lending — Credit lines, installment loans, or commercial lending APIs
- Compliance tooling — KYC, AML, transaction monitoring, and onboarding
They sit between your platform and the bank: you integrate with their APIs; they manage the bank partnership, regulatory interface, and often core processing.

How to Compare Banking as a Service Providers
When comparing banking as a service providers, focus on these dimensions:
- Geography — Which countries and regions do they support? Ensure they cover your target market.
- Bank partners — Quality and stability of sponsor banks. Some offer single-bank; others multi-bank flexibility.
- Product breadth — Accounts only, or also cards, lending, payments? Match to your use case.
- Compliance support — KYC, AML, and onboarding tooling. Built-in or bring your own?
- Pricing — Per-account, per-transaction, platform fees. Model total cost at your scale.
- Developer experience — Documentation, sandbox, SDKs. Critical for integration speed.
A detailed comparison table is available on the BaaS Providers page, including developer portal links and target markets.
Banking as a Service vs. Embedded Finance
BaaS is a subset of embedded finance. BaaS focuses specifically on regulated banking products—deposits, accounts, and cards issued by a licensed bank. Embedded finance is the broader category that includes BaaS plus non-bank services like card issuing without a bank (e.g. Marqeta, Lithic), payments, lending, AP/AR, compliance, and more.
Many providers offer both: Unit and Stripe Treasury are BaaS platforms that also offer card issuing. For the full embedded finance ecosystem—BaaS, card issuing, lending, payroll—see our embedded finance platform directory. For definitions, see What is embedded banking? and embedded banking (glossary).
