If your incoming payments rely on customers entering reference numbers correctly, your reconciliation process will always have a potential weak point. References are frequently missed, mistyped, shortened, or reused across different payment systems. This leaves operations teams to manually investigate which customer, invoice, wallet, or use case a specific payment belongs to. 

The solution to this is virtual account infrastructure. With ClearBank, for instance, businesses can assign unique virtual accounts or virtual International Bank Account Numbers (vIBANs) to customers, invoices, merchants, employers, or internal use cases.  

This allows incoming payments to be matched automatically based on the unique account details used, rather than relying on a payer to enter a reference number correctly.

ClearBank is a UK and EU-authorised B2B bank that helps businesses assign unique account details through virtual accounts and vIBANs. The specific structure depends on whether you need reconciliation at the customer, invoice, merchant, employer, or use-case level.  

By programmatically generating these details, you ensure that every incoming transaction carries its own identification within the destination account.

Payment references are inherently unreliable. This is because payer behaviour is unpredictable: customers forget to include a reference in the first place, mistype alphanumeric strings, or reuse old references for new invoices. Additionally, some bank systems truncate payment data during transit, cutting off the very reference your team needs to identify the funds. 

And the operational impact can be significant. Payments might land in your bank account, but your business doesn't know who the money belongs to without manual investigation. This creates a bottleneck that prevents you from scaling your product efficiently. 

With virtual accounts, the account number itself becomes the identifier. Payments are matched by the specific account details used rather than by a free-text reference field. As Chris Scrimgour, Head of Fintech, UK, at ClearBank, explains:  

"The virtual account allows inbound and outbound payments and Direct Debits to be set up. They look, feel, and act like a real account."

ClearBank virtual accounts are linked to underlying real accounts. This means your business doesn't need to open a separate physical bank account for every customer, invoice, or use case. 

Instead, funds are centralised in a real account while the virtual layer provides the necessary segregation for reporting and reconciliation.

Here’s what you can do using ClearBank’s infrastructure:

ClearBank provides an API-first approach to account management. You can open virtual accounts in real time, 24 hours a day, 365 days a year. This programmatic flexibility allows platforms to generate unique account details instantly during a customer onboarding flow or at the moment an invoice is generated.  

Our API comes with clear developer documentation and a sandbox testing environment, so your team can get set up quickly.

For many businesses, simply having a virtual ledger isn't enough; they need addressable identifiers. ClearBank supports millions of virtual accounts, each of which can be assigned its own addressable vIBAN.  

These vIBANs allow payments to be routed directly to the correct sub-ledger, ensuring real-time payment processing and immediate visibility.

The transition from manual matching to automatic reconciliation follows a logical flow through the banking API: 

1. A customer, invoice, merchant, or use case is assigned a virtual account or vIBAN. 
2. The payer sends money to those unique account details. 
3. The payment arrives into the underlying account structure. 
4. ClearBank sends transaction data through the API immediately upon settlement. 
5. The business matches the payment to the right customer, invoice, wallet, or ledger entry automatically. 
6. Exceptions can be flagged for review instead of requiring your team to manually check every payment.

Choosing the right partner is about more than just the ability to create accounts. You need a setup that scales with your volume and integrates with your tech stack.  

Key criteria include: 

• Support for both virtual accounts and addressable vIBANs 
• API-first infrastructure for programmatic account creation 
• Real-time transaction data and balance updates 
• Webhooks or event-driven notifications to trigger internal workflows 
• High scalability, such as the ability to manage millions of accounts 
• Flexibility in account structures to mirror your business logic 
• Support for UK payment schemes like Faster Payments and Bacs 
• Reliable reconciliation feeds that minimise downtime

Businesses that want payments to reconcile automatically should use virtual accounts or vIBANs that make the destination account the identifier. This reduces reliance on payment reference numbers and eliminates the need for manual matching.  

ClearBank's cloud-native platform provides the infrastructure to build these automated flows, allowing your operations team to focus on growth rather than investigation.
