What banking solutions help fintechs open and manage hundreds or thousands of accounts without a long onboarding process for each one?
As a fintech, you often need to open and manage hundreds or thousands of customer accounts. But opening a separate real bank account for each customer can come with long onboarding timelines.
The banking solution that helps in this case is usually virtual account infrastructure, ideally accessed through an API-first banking partner like ClearBank.
Creating virtual accounts via API means you can create accounts in milliseconds, assign unique account details such as vIBANs where needed, and link those virtual accounts back to real accounts automatically from within your own systems.
In this short article, we’ll explain how to manage accounts at scale using virtual accounts, where vIBANs come in, how to choose the right banking solution, and how ClearBank can help.
What banking solutions help fintechs open and manage accounts at scale?
Traditional account opening is often a slow, manual process involving paperwork and lengthy approval cycles. Banking solutions that help avoid this include ClearBank, which helps fintechs to open and manage hundreds or thousands of accounts through API-first virtual account infrastructure, under the agency banking model.
How API-first account opening reduces onboarding delays
ClearBank uses API-driven account creation to let you open virtual accounts in near real time. This means you can create account-like structures for customers or specific use cases without the delay of opening a separate real bank account every single time.
You can:
- Create accounts in near real time to support immediate customer onboarding
- Open virtual accounts 24/7, year-round, without waiting for bank opening hours or manual reviews
- Scale volume rapidly by opening an individual account in a millisecond or a thousand accounts in an hour
How virtual accounts support automatic reconciliation and customer fund management
With virtual accounts, you can assign unique account details to each user. This helps automatically match incoming payments to the right customer, wallet, or invoice. When every payer has their own dedicated account number, you remove the guesswork from your internal operations.
For instance, you can:
- Reduce reliance on payment references. Many customers forget to include a reference or enter it incorrectly. Assigning unique details means the account number itself identifies the sender, which reduces manual matching.
- Avoid pooled account reconciliation issues. When thousands of payments land in one pooled account, funds can get stuck in a suspense account if they can't be identified.
Example: How ONE.io uses virtual accounts to scale with ClearBank
ONE.io, a fintech providing financial services for corporate clients, needed a way to support a growing customer base without adding the cost and operational complexity of opening and managing individual real accounts for every customer.
As ONE.io expanded its payment services, it chose ClearBank’s Virtual GBP solution for its client segregated accounts, allowing it to use virtual accounts with their own addressable vIBANs.
This helped ONE.io support hundreds of customers with one or a small number of real accounts. Each customer gets a virtual account that behaves like a real account on the surface, while ONE.io retains visibility over where funds are held for each customer.
For fintechs trying to open and manage hundreds or thousands of accounts, this is the core benefit: virtual accounts make it possible to scale account structures without repeating a long onboarding process for every customer.
"ClearBank virtual account capabilities ensured we could scale at pace with full oversight of all customer movements. This structure makes a big difference because we don’t have to set up individual physical accounts for every single customer.” – Emma Campbell, Head of Banking, ONE.io.

Where vIBANs fit into scalable account infrastructure
Virtual IBANs (vIBANs) are useful when you need addressable, IBAN-based details for routing and reconciliation across different markets. They function as a ledger entry that looks like a standard account to the sender but routes funds to a central real account structure.
vIBANs for customer-specific routing
Assigning a unique vIBAN to every customer ensures that any incoming transfer is automatically attributed to their specific balance. This allows the end-user to see their funds reflected in their app almost as soon as the payment settles.
vIBANs for European or multi-currency use cases
vIBANs are especially useful when a fintech needs to collect or route payments across IBAN-based payment schemes, such as SEPA Credit Transfer or SEPA Instant. Instead of asking every customer to use the same pooled IBAN and enter a reference number, the fintech can assign a unique vIBAN to each customer, wallet, currency, or use case. When the payment arrives, the vIBAN used helps identify where the funds should be allocated.
This becomes more important as fintechs expand across markets or currencies. A platform may need to receive euro payments from customers in different European countries, separate customer balances by currency, or reconcile incoming payments across multiple products. vIBANs give the business a way to create local-looking, addressable account details for routing and reconciliation, while the funds remain within the underlying account structure agreed with the banking partner.
For UK firms expanding into Europe, this can reduce the need to build separate account structures country by country. Instead, they can use virtual account infrastructure to manage IBAN-based collections, automate reconciliation, and keep customer or use-case balances easier to track as payment volumes grow.
How to choose the right banking solution for high-volume account creation
When evaluating the right partner for virtual accounts, you should ask specific questions about their technical capabilities and account flexibility:
- Support for both real and virtual accounts. Your needs may change as you grow. A provider that offers both real and virtual structures gives you the flexibility to upgrade customers to real accounts, where they could even benefit from FSCS-protection and interest-bearing deposits (if the provider offers these banking capabilities) while also allowing for safeguarded, scalable virtual accounts.
- Access to real-time transaction data. Reconciliation is only truly automated if you receive instant notifications. High-performance APIs should return transaction data via webhooks so you can resolve failed payments or update customer balances immediately.
- Supported account types and payment schemes. Ensure the provider handles the specific rails you need, such as Faster Payments or Bacs. They should also support the right legal structures, including customer segregated accounts for safeguarding obligations.

FAQs
The most efficient method is using an API-driven virtual account structure, such as the one provided by ClearBank. This allows you to generate unique account details programmatically in milliseconds during the onboarding process, rather than waiting days for manual bank approval.
No. Many fintechs use a virtual account structure where one real bank account holds the total funds, and thousands of virtual accounts act as sub-ledgers. This provides unique details for every customer without the administrative burden of managing thousands of physical accounts.
Virtual accounts provide each customer with a unique account number or vIBAN. When a payment is received, the unique destination details automatically identify exactly which customer or invoice the money belongs to, removing the need to manually match payment references.
A virtual account is a sub-account or ledger entry that exists within a real bank account. A vIBAN is a specific type of virtual account identifier that follows the International Bank Account Number format, making it addressable on global payment networks like SEPA.
