Breaking Down Trust Barriers in Banking as a Service Adoption in 2026

Banking as a Service can help a nonbank business add financial products to its customer experience without building a bank from the ground up. Depending on the arrangement, a company may be able to offer deposit accounts, payment services, cards, lending products or other embedded financial features through one or more regulated financial institutions and technology providers.

The technology may be relatively easy to demonstrate. Establishing trust is more difficult.

A successful BaaS programme must show that customer funds and data are protected, transactions are recorded accurately, regulatory responsibilities are understood and customers can continue accessing essential services when a provider experiences an outage, financial problem or security incident.

This guide explains the most important trust barriers in Banking as a Service and the controls organizations should evaluate before selecting, launching or expanding a BaaS partnership.

Key takeaways:

BaaS is usually a network of regulated banks, fintech companies, processors and other service providersâ€”not one standalone technology product.
The exact legal and operational structure matters more than the marketing label placed on the service.
A bank does not eliminate its regulatory responsibilities by assigning activities to a fintech or middleware provider.
Data encryption alone is not enough; organizations also need access controls, incident response, retention rules and subcontractor oversight.
Transaction and deposit records must be complete, accurate, reconcilable and available during disruptions.
Deposit-insurance statements must accurately identify the insured bank and the conditions under which coverage may apply.
Service-level agreements should address uptime, recovery, support, data access and meaningful remedies.
Compliance responsibilities should be assigned in detail rather than described using vague statements that every party will â€œfollow applicable law.â€
Customer complaints are an important source of operational and compliance information.
Every BaaS relationship needs an exit and transition plan before the programme launches.

What Is Banking as a Service?

Banking as a Service, commonly abbreviated as BaaS, is an industry term used for arrangements in which banking capabilities are made available through another company's product or interface.

For example, a nonbank company might offer customers:

A deposit account
A debit or prepaid card
Payment processing
Peer-to-peer transfers
A business account
A lending product
Expense-management tools
Other embedded financial services

The customer may interact primarily with the nonbank brand, while a regulated bank provides one or more underlying financial products.

A BaaS arrangement may involve:

A sponsor or partner bank
A customer-facing fintech or nonbank brand
A BaaS platform or middleware provider
A core banking or ledger provider
A payment processor
A card network or programme manager
Identity-verification providers
Fraud-monitoring services
Customer-support vendors
Cloud and data-hosting providers

The number of participants can create efficiency, but it can also make responsibility difficult to understand.

BaaS Is Not the Same as an Ordinary Software Subscription

A conventional software provider may supply a tool without becoming deeply involved in the customer's regulated financial activity.

A BaaS provider may support functions such as:

Account opening
Identity verification
Transaction processing
Ledger management
Payment instructions
Customer communications
Compliance monitoring
Complaint resolution

Failure in one of these functions can affect customersâ€™ money, legal rights and access to essential financial services. Due diligence should therefore extend beyond software features and integration speed.

Why Trust Is Difficult in BaaS

A traditional banking relationship is usually easier for customers to identify: the bank opens the account, displays its name and provides the service.

In a BaaS model, customers may see one brand while several organizations operate behind it.

This can create uncertainty about:

Which organization holds the money
Which company is the legal creditor
Who maintains the transaction records
Who investigates fraud
Who resolves complaints
Whether deposits are insured
What happens when one participant fails

Trust grows when the programme can answer those questions clearly and consistently.

1. Unclear Roles and Responsibilities

One of the most significant BaaS trust barriers is uncertainty about which party performs each activity.

A high-level description such as â€œthe fintech manages the customer while the bank handles complianceâ€ is usually inadequate. Customer service and regulatory compliance involve many separate tasks.

The operating model should identify responsibility for:

Customer acquisition
Marketing approval
Account-opening disclosures
Identity verification
Customer due diligence
Sanctions screening
Fraud monitoring
Transaction monitoring
Account restrictions
Funds availability
Customer complaints
Error resolution
Regulatory reporting
Record retention
Data-security incidents
Programme termination

Each activity should have:

A responsible party
An approving party where needed
Defined escalation procedures
Required records
Performance standards
Oversight and audit procedures

2. Data Security

BaaS arrangements can involve sensitive identity, account, transaction and business information moving between several systems.

The security review should cover the complete data lifecycle:

Collection
Transmission
Processing
Storage
Access
Sharing
Archiving
Deletion

Important controls may include:

Encryption in transit and at rest
Multifactor authentication
Role-based access
Least-privilege permissions
Privileged-access monitoring
Network segmentation
Vulnerability management
Secure software-development practices
Penetration testing
Security logging
Data-loss prevention
Employee security training

A security certificate or audit report can provide useful evidence, but it should not be treated as proof that every control needed for the proposed BaaS programme is operating effectively.

3. Data Ownership and Permitted Use

Organizations should determine who owns or controls each category of data and how it may be used.

The contract and privacy notices should address:

Customer account information
Identity-verification records
Transaction data
Derived analytics
Fraud indicators
Customer-support records
Marketing data
Model outputs

Questions to resolve include:

Can the provider use customer data to develop another product?
Can information be shared with affiliates?
Can aggregated information be sold?
Who responds to a customer privacy request?
How is data returned or deleted after termination?
Which records must be retained by law or contract?

The parties should avoid using vague contractual language that allows sensitive financial information to be used for almost any business purpose.

4. Cybersecurity Incident Response

Every BaaS programme should assume that a security incident may eventually occur.

The incident-response plan should define:

What constitutes a reportable incident
How quickly each party must be informed
Who leads the investigation
Who preserves evidence
Who communicates with customers
Who communicates with regulators
How compromised credentials are disabled
How affected systems are restored
How losses and remediation costs are allocated

Notification periods should be based on the seriousness of the incident rather than allowing the vendor to wait until its complete investigation has ended.

The plan should also be tested through exercises involving the bank, fintech, middleware provider and other critical parties.

5. Service Reliability

A BaaS outage can prevent customers from viewing balances, receiving payments, making purchases or accessing funds.

Reliability should be measured using more than a broad annual uptime percentage.

Review:

Availability by critical service
Transaction-processing success rates
Payment latency
API error rates
Scheduled maintenance
Maximum outage duration
Incident frequency
Recovery performance
Customer-support availability

An app may remain technically online while its most important payment or account functions are unavailable. Service-level reporting should distinguish between complete and partial outages.

6. Business Continuity and Disaster Recovery

Business-continuity planning addresses how essential activities will continue after a disruption.

The assessment should cover events such as:

Cloud outages
Cyberattacks
Payment-network failures
Data corruption
Vendor insolvency
Loss of critical employees
Natural disasters
Telecommunications failures

Important measures include:

Recovery time objective: The target time for restoring a service.
Recovery point objective: The maximum acceptable period of data loss.
Maximum tolerable downtime: The longest disruption the business can withstand.

Request evidence that recovery processes have been tested under realistic conditions. A written plan that has never been exercised provides limited assurance.

7. Accurate Ledgers and Transaction Records

BaaS trust depends on the ability to determine how much money belongs to each customer and how every transaction affected that balance.

The programme should identify the authoritative system of record for:

Customer identities
Account balances
Pending transactions
Settled transactions
Fees
Returns
Chargebacks
Disputes
Interest

When several ledgers or processors are used, the parties need regular reconciliation between:

The bank's records
The fintech's customer records
The middleware ledger
Payment-network settlement files
Custodial or omnibus account balances

Unexplained differences should be investigated quickly, documented and escalated according to defined thresholds.

8. Customer-Fund Ownership Records

Some programmes pool funds belonging to many end users in one or more custodial or omnibus accounts.

In these arrangements, records should identify:

Each beneficial owner
The amount belonging to that owner
The account in which the funds are held
Pending and settled transactions
Any ownership or account-capacity distinctions

The programme should be able to reproduce accurate ownership records even when a middleware provider becomes unavailable.

Questions to ask include:

Who maintains the end-user subledger?
How often is it reconciled?
Can the bank independently access it?
Can the records be exported in a usable format?
How are discrepancies resolved?
What happens if the recordkeeper fails?

9. Deposit-Insurance Communications

A nonbank fintech company is not itself an FDIC-insured bank.

When a programme offers a deposit product through an insured bank, customer communications should accurately explain:

The legal name of the bank holding the deposit
That insurance protects against failure of the insured bankâ€”not failure of the fintech
That legal limits and account-ownership rules apply
That pass-through coverage depends on applicable requirements being satisfied
That nondeposit products are not FDIC-insured

A statement such as â€œyour money is FDIC insuredâ€ can be incomplete or misleading when it fails to identify the insured institution or explain the arrangement accurately.

Marketing, onboarding, account statements, support scripts and website disclosures should use consistent language.

10. Regulatory Compliance

A BaaS programme may be subject to different requirements depending on whether it offers deposits, payments, cards, lending or another financial service.

Relevant areas can include:

Consumer financial protection
Fair lending
Electronic transfers
Credit disclosures
Funds availability
Privacy
Credit reporting
Bank Secrecy Act and anti-money-laundering requirements
Customer identification
Sanctions compliance
Unfair, deceptive or abusive acts or practices
State licensing requirements

The precise requirements depend on the product, parties, customers and jurisdictions.

The compliance matrix should identify:

Applicable requirement
Responsible party
Required control
Evidence produced
Testing frequency
Escalation owner

11. Anti-Money-Laundering and Financial-Crime Controls

BaaS programmes can grow rapidly and attract customers from many locations. This makes financial-crime controls an important trust consideration.

The operating model should address:

Customer identification
Beneficial-ownership information where applicable
Sanctions screening
Transaction monitoring
Suspicious-activity escalation
Fraud investigations
Account restrictions and closures
Record retention

Automated tools should be validated and supported by appropriately trained employees.

The parties should establish how alerts are assigned, investigated, closed and reviewed for quality.

12. Fraud Management

Fraud risk may involve:

Identity theft
Synthetic identities
Account takeover
Authorized-push-payment scams
Card fraud
Check fraud
Merchant fraud
First-party fraud

The programme should establish:

Fraud thresholds
Real-time and post-transaction controls
Manual-review procedures
Account-freeze authority
Customer-notification procedures
Loss-allocation rules
Appeal and error-resolution processes

Controls should balance loss prevention with the risk of incorrectly blocking legitimate customers from accessing their money.

13. Fair and Transparent Customer Treatment

Trust can be damaged when the customer-facing company presents benefits prominently while hiding important limitations.

Customers should be able to understand:

Who provides the financial product
Which fees apply
When funds become available
How payments are processed
How to report an error
How to close an account
How long a restriction may last
What happens to remaining funds

The sponsor bank should have appropriate review and approval rights over customer-facing materials related to the bank's products.

14. Customer Complaints

Complaints can reveal problems that do not appear in technical performance reports.

Examples include:

Unexpected account closures
Long fraud-investigation delays
Missing deposits
Incorrect balances
Misleading deposit-insurance claims
Unexplained fees
Inaccessible customer support
Delayed refunds

The programme should track:

Complaint volume
Complaint category
Severity
Resolution time
Repeat complaints
Root cause
Remediation

The bank should receive sufficient information to evaluate complaint patterns, even when the fintech operates first-line customer support.

15. Vendor Credibility and Experience

A polished product demonstration does not establish that a BaaS provider can operate a regulated financial programme at scale.

Review:

Operational history
Leadership experience
Banking and compliance expertise
Client references
Past outages
Customer complaints
Litigation
Regulatory actions
Audit findings
Remediation history

Ask references about:

Implementation quality
Reporting accuracy
Incident communication
Support responsiveness
Contract flexibility
Performance during growth
Exit or migration experience

16. Financial Condition

A provider can have strong technology and still present continuity risk if it lacks sufficient funding or depends on one major customer.

Financial due diligence may include:

Audited financial statements
Cash reserves
Revenue concentration
Profitability
Cash burn
Debt obligations
Funding sources
Insurance coverage
Contingency financing

For an early-stage provider without a long financial history, evaluate whether the relationship can be structured to reduce the impact of provider failure.

Possible controls include:

Data-access rights
Source-code escrow where appropriate
Transition assistance
Backup providers
Bank-controlled records
Shorter termination rights

17. Fourth-Party and Subcontractor Risk

A BaaS platform may rely on subcontractors for identity verification, cloud hosting, payment processing, customer support or fraud monitoring.

The organization should understand:

Which subcontractors are used
Which activities they perform
Which data they receive
Where data is stored
Whether subcontracting requires approval
How performance is monitored
How incidents are reported

Contractual responsibility does not disappear merely because a critical service is performed by a fourth party.

18. Concentration Risk

Concentration risk can arise when many critical functions depend on one provider, cloud region, processor or sponsor bank.

Evaluate concentration by:

Provider
Technology stack
Cloud environment
Geography
Payment network
Banking partner
Critical employee

The organization should understand whether a single failure could interrupt:

Account access
Payments
Customer support
Compliance monitoring
Transaction records

19. Rapid Growth

A BaaS programme may grow more quickly than the controls, staffing and technology supporting it.

Before increasing customer or transaction volume, review:

Operational capacity
Fraud losses
Complaint volumes
Compliance staffing
Reconciliation exceptions
System latency
Customer-support wait times
Liquidity and settlement needs

The programme should establish thresholds that require additional approval before material expansion.

20. Contract Quality

A strong contract converts broad promises into measurable rights and responsibilities.

The agreement should address:

Scope of services
Roles and responsibilities
Service levels
Security standards
Compliance requirements
Audit and testing rights
Regulatory access
Customer complaints
Incident notification
Data ownership and use
Subcontractors
Insurance
Indemnification
Termination
Transition assistance

The contract should allow the bank and other authorized parties to obtain the information needed to oversee the programme.

21. Service-Level Agreements

Service-level agreements should be specific enough to measure.

Area	Possible measure
Availability	Uptime for each critical service
Incidents	Time to acknowledge, contain and resolve
Transactions	Processing success rate and latency
Reconciliation	Completion time and unresolved exceptions
Customer support	Response and resolution times
Complaints	Escalation and closure deadlines
Data delivery	Accuracy, completeness and timeliness

Service credits alone may be inadequate when an outage prevents customers from accessing funds. The agreement should include escalation, remediation and termination rights for serious or repeated failures.

22. Audit and Access Rights

A partner cannot provide effective oversight when it cannot inspect records or test controls.

Contractual rights may include:

Access to policies and procedures
Access to independent audit reports
Right to request remediation evidence
Right to conduct or commission testing
Access to relevant customer and transaction records
Access for regulators and examiners
Notification of material audit findings

Audit rights should extend to critical subcontracted activities where appropriate.

23. Change Management

A provider may change its technology, policies, subcontractors or product design after launch.

The contract should identify changes requiring advance notice or approval, such as:

Material product changes
New customer groups
New jurisdictions
New subcontractors
Changes to the system of record
Material security changes
New fees
New marketing claims

Material changes should be reviewed before implementation rather than discovered through customer complaints.

24. Exit and Transition Planning

Every BaaS relationship eventually changes or ends.

Termination may result from:

Strategic changes
Poor performance
Regulatory concerns
Security incidents
Provider insolvency
Bank-partner changes
Acquisition

The exit plan should address:

Customer communications
Continued access to funds
Pending transactions
Account migration or closure
Data export
Record retention
Complaint handling
Regulatory reporting
Destruction of unnecessary data

The organization should test whether customer, balance and transaction information can be transferred to another provider in a complete and usable format.

A BaaS Due-Diligence Framework

Step 1: Define the Proposed Product

Document:

The customer group
The financial product
The expected volume
The jurisdictions involved
The customer-facing brand
The intended flow of funds

Step 2: Map Every Participant

Create a diagram showing:

Every organization
Every critical system
Every data flow
Every money flow
Every system of record

Step 3: Identify Applicable Requirements

Develop a legal and compliance assessment based on the actual product and transaction structure.

Step 4: Assess the Provider

Review experience, financial condition, compliance, technology, security, resilience and subcontractors.

Step 5: Test the Operating Model

Walk through realistic events such as:

A customer disputes a transfer.
A deposit does not appear.
The ledger and bank balance do not reconcile.
A cloud provider fails.
A fintech becomes insolvent.
A customer cannot access funds.
A data breach occurs.

Step 6: Negotiate the Contract

Ensure contractual rights support the controls and oversight identified during due diligence.

Step 7: Complete Prelaunch Testing

Test:

Customer onboarding
Disclosures
Payments
Reconciliation
Fraud alerts
Complaints
Incident escalation
Account closure

Step 8: Launch in Controlled Stages

Use volume limits and defined review points before expanding the programme.

Step 9: Monitor Continuously

Review operational, financial, compliance and customer-outcome information.

Step 10: Reassess After Material Changes

A relationship that was acceptable at launch may become higher risk after rapid growth, product changes or financial deterioration.

BaaS Provider Red Flags

The provider will not identify every critical subcontractor.
Roles and responsibilities are described only at a high level.
The bank cannot access end-user balance or transaction records independently.
Reconciliation relies heavily on manual spreadsheets.
The provider refuses meaningful audit rights.
Incident notification begins only after the provider completes its investigation.
The company cannot produce tested continuity or recovery evidence.
Marketing implies that the fintech itself is FDIC-insured.
The provider has experienced rapid growth without matching compliance or support staffing.
Customer complaints are not shared with the bank.
Financial information is unavailable or significantly outdated.
The provider cannot explain how data will be returned after termination.
The exit plan assumes the provider will remain cooperative during insolvency.

Questions to Ask a BaaS Provider

Which regulated financial institutions participate in the programme?
Which party provides each financial product?
Who maintains the authoritative ledger?
How often are balances and transactions reconciled?
Can the bank access end-user records independently?
Which subcontractors perform critical activities?
Where is customer data stored?
Which security assessments are available?
When must a security incident be reported?
What are the recovery time and recovery point objectives?
How are customer complaints tracked and reported?
Who approves marketing and disclosures?
How are deposit-insurance statements reviewed?
What financial and insurance information is available?
How does the provider manage rapid growth?
What audit and regulatory access rights are available?
How will data and accounts be transferred after termination?

Frequently Asked Questions

Is a BaaS provider a bank?

Not necessarily. A BaaS provider may be a regulated bank, a technology platform, middleware provider or another company. The legal role of each participant should be identified clearly.

Does using BaaS remove a bank's compliance responsibility?

No. A bank's use of a third party does not eliminate its obligation to operate safely and comply with applicable laws and regulations.

Is BaaS always cloud-based?

No. Cloud services are common, but BaaS describes a business and service-delivery arrangement rather than one specific hosting method.

Is a security certification enough?

No. Certifications and independent reports can support due diligence, but the organization must determine whether the provider's actual controls fit the product and risks involved.

Are funds held through a fintech automatically FDIC-insured?

No. The nonbank fintech itself is not FDIC-insured. Potential coverage depends on whether funds are deposited at an insured bank and whether the applicable ownership and recordkeeping requirements are satisfied.

Who should handle customer complaints?

The customer-facing company may provide first-line support, but the bank should receive enough complaint information to oversee the product and identify operational or compliance problems.

Why is reconciliation important?

Reconciliation confirms that the bank, fintech, processor and ledger records agree. Unresolved differences may indicate processing errors, missing transactions or inaccurate customer balances.

What is fourth-party risk?

It is risk introduced by a provider's own subcontractors or service providers. A BaaS programme may depend on several fourth parties for critical functions.

Should a BaaS contract include an exit plan?

Yes. The agreement should address customer access, data transfer, pending transactions, record retention and transition support after termination.

How often should a provider be reassessed?

Monitoring should be continuous and proportionate to risk. A deeper reassessment may be needed after material product, ownership, financial, security or subcontractor changes.

Review business-continuity evidence.
Verify customer-fund recordkeeping.
Test reconciliation processes.
Review deposit-insurance language.
Evaluate complaints and customer support.
Review provider experience and financial condition.
Identify concentration and fourth-party risks.
Negotiate measurable service levels.
Obtain audit, data and regulatory access rights.
Establish change-approval procedures.
Complete prelaunch testing.
Launch under controlled limits.
Document and test the exit plan.

Final Thoughts

Trust in Banking as a Service cannot be created by branding, an attractive application or a security certificate alone. It depends on whether every participant can demonstrate control over customer data, transactions, regulatory responsibilities and operational continuity.

The strongest programmes establish clear accountability, maintain accurate records, communicate deposit-insurance information carefully and give the regulated bank meaningful oversight of customer-facing activities.

Due diligence should continue after the contract is signed. Performance, complaints, reconciliation, financial condition, security and subcontractors must be monitored as the programme develops.

A BaaS partnership should not launch until the organizations know how it will operate during ordinary conditions, how it will respond to failure and how customers will be protected when the relationship eventually ends.
