BaaS lets companies offer regulated financial tools without becoming banks. Through technology providers and partnerships, one business can add payments or accounts to its product. Customers can then manage more of their financial activity within an existing digital experience.
The market is expanding quickly. One report valued the BaaS market at $19.65 billion in 2021 and projects it will approach $75 billion by 2030. Another forecast puts embedded finance at $138 billion by 2026, nearly triple its earlier size. These figures point to strong growth and rising revenue potential.
For companies, the appeal lies in adding useful financial features without building regulated systems from scratch. APIs connect apps with financial infrastructure, while partners help support compliance and account functions. Done well, this model can improve the customer experience and create new value for businesses.
This guide explains how the model works, where partnerships fit, and what to weigh before launch. It also explores real-world examples, possible business benefits, and key operational concerns. The goal is to help readers assess whether embedded financial tools fit their plans and their users’ needs.
What is banking as a service?
BaaS connects licensed banks with nonbank companies through APIs. This model gives businesses access to regulated account, card, or payment functions without obtaining their own banking license. The bank remains central: it holds the license and supports regulated activity, while each company shapes its customer-facing product.
How BaaS differs from embedded finance
Embedded finance describes financial services placed inside nonfinancial experiences, including shopping apps or business software. BaaS differs because it provides technology and bank relationships that enable those experiences. Put simply, embedded finance describes where users find money tools; BaaS describes part of how providers deliver them.
Why businesses use bank infrastructure without becoming banks
Gartner predicted that, by year-end 2024, 30% of banks holding more than $1 billion in assets would adopt this model. One forecast puts market growth at a 16.2% compound annual rate through 2030. Solarisbank and the Handelsblatt Research Institute surveyed 2,000 people; 61.4% said they were open to receiving financial services from online platforms.
How BaaS connects businesses to banking infrastructure
Three participants shape this flow: the licensed sponsor bank, an API platform, and the company’s product. The bank runs regulated operations, while the BaaS provider links its core systems with company software. This banking service model lets customers use financial tools within products they already know.
Who connects the product and the bank?
The business combines customer-facing software with backend systems. The platform carries requests between those systems and the bank’s core. This setup can bring accounts and cards into one product, while the licensed institution retains its role in regulated activity.
How do APIs support each step?
First, teams collect identity data and complete KYC or KYB checks. The bank then issues an account or cards under its bank identification number (BIN). APIs route payments through ACH, wires, RTP, or card rails.
Partners monitor transactions, disputes, limits, and ledger entries. Integration does not remove compliance duties: regulators still hold partnerships accountable, and banks must actively manage risk.
| Stage | What happens | Key participants |
|---|---|---|
| Onboarding | Identity data is checked through KYC or KYB | Business and bank |
| Account setup | Accounts or cards are issued under the bank’s BIN | Bank and platform |
| Ongoing operations | Payments, disputes, limits, and ledger entries are tracked | Business and partners |
Banking services and products businesses can offer
Financial features work best when they solve clear customer needs. Companies can select tools that fit their product, support daily tasks, and create new revenue opportunities. A focused mix can add value without making the core experience feel crowded.
Accounts, cards, and payment capabilities
Account options may include statements, transaction histories, balance monitoring, check issuing, remote deposit capture, and controls. Businesses can also offer debit cards in virtual, physical, or tokenized form, with spending limits. ACH, wires, RTP, and card rails support purchases and customer payouts.
Wallets, lending, and treasury tools
PayPal and Venmo show how stored-value wallets keep funds inside an app. Embedded credit and working capital can help sellers manage cash flow. Treasury tools may automate bill pay, book transfers, and account monitoring. Treasury Prime supports these capabilities, plus commercial and retail accounts.
The right mix depends on customer needs and the wider fintech company strategy. These financial solutions can help firms offer useful products while keeping core operations focused.
How BaaS can support customer experiences and business growth
Financial tools can make an existing product more useful and convenient. They may also help companies build stronger customer ties and open new revenue paths.
Walmart, IKEA, and Mercedes are examples of large companies offering banking services through their platforms. Their products show how financial features can fit into familiar experiences.
New revenue opportunities, faster launches, and more integrated experiences
With embedded finance, accounts, cards, or payments can fit into an established product experience. This integration may give customers more reasons to return and create added value for the business.
- Choose features that address clear customer needs.
- Estimate revenue potential before launch.
- Plan for ongoing operations and risk.
Scale varies across providers. Synapse reports 18 million end users and 91 million transactions each year; these figures reflect its own activity, not an industry benchmark. Treasury Prime works closely with 10 bank partners and says its customers can launch products in weeks. This fintech model may shorten time to market, but businesses should weigh growth against ongoing duties.
Bank partnerships, compliance, and risk responsibilities
Clear oversight helps protect customers and keep embedded finance reliable. The sponsor bank and business have distinct duties, but they must coordinate throughout each program.
How oversight works across partners
U.S. banking agencies repeatedly remind banks to manage third-party risk. Bank partners therefore expect clear controls, regular reporting, and named owners for operations. Regulators still hold partnerships accountable for compliance.
Controls for identity, fraud, and operations
Identity checks, transaction monitoring, disputes, and limits need ongoing review, even after account opening. Strong best practices also include frequent reconciliation, immutable journal entries, dual approval for production keys and payouts, and alerts for failed webhooks.
Reduce privacy and fraud exposure by limiting personally identifiable information (PII), classifying data, rotating keys, and signing sensitive data. Document decisions when fraud rules wrongly block valid activity or miss suspicious activity. These steps support finance products and help keep each banking service dependable.
| Control area | Useful practice | Purpose |
|---|---|---|
| Customer and transaction review | Check identity, monitor activity, and review disputes and limits | Spot misuse throughout account use |
| Operations | Reconcile often; use immutable journals and dual approvals | Improve accuracy and accountability |
| Data and fraud | Limit PII, rotate keys, and document rule outcomes | Protect privacy and refine detection |
Choosing a BaaS provider and preparing to integrate banking
Set launch goals before choosing technology. Compare each BaaS provider by bank-partner experience, industry fit, available services, API depth, compliance support, pricing, and direct bank communication. Confirm that product features match customer needs and that support covers launch and daily operations.
Assessing account structures and partner fit
Account design affects control and exposure. On-core accounts sit within the bank’s core system and can offer direct bank involvement. Individual FBO accounts hold funds for one business, with different setup and flexibility needs. Pooled FBO accounts serve multiple businesses, but one company’s risk issue may trigger scrutiny or closure for others in the pool.
Treasury Prime works with 10 bank partners and highlights industry fit, coverage, implementation support, and provider flexibility. Railsbank announced $37 million in equity funding to expand in the United States. Treat these as examples, not guarantees of fit or performance.
Planning reliable operations
Before launch, test the integration, align ledgers, process webhooks reliably, and reconcile often. Set clear owners across the provider, bank, and business. Review compliance duties, escalation paths, and best practices before scaling. Strong planning can reduce operational risk and support dependable financial products over time.
Conclusion
BaaS connects company products to licensed banking capabilities, while the bank and business each keep clear duties. The model creates value only when services meet customer needs and an experienced partner can support safe delivery. Adding features without purpose can add cost and confusion.
Start with program RACI agreed with the sponsor institution. Prototype core flows, then coordinate onboarding, risk alerts, and finance reconciliation. Document controls, assign owners, and review records often. These steps help companies protect customers and support reliable operations.
