How to connect multiple business bank accounts to your platform with open banking

Many SMEs manage several bank accounts across different providers. Connecting them all manually is time-consuming, error-prone, and often results in delayed financial visibility. With Yapily, you can bring all that data together securely through a single open banking API, giving your customers one clear view of their finances while using regulated open banking infrastructure designed to support PSD2 requirements and GDPR-aligned data handling.

Why connect multiple business accounts through open banking?

If you’re a PSP, fintech, or SaaS platform serving businesses, your users likely operate across multiple banks: one for payments, another for savings, perhaps a third for credit.By integrating with Yapily, you can:

• Aggregate balances and transactions from multiple banks into one unified dashboard

• Automate reconciliation using verified, near-real-time data

• Support account-to-account payments through regulated payment initiation (PIS)

• Support credit and risk decisions with richer financial insight

• Offer a seamless, secure linking experience that builds user trust

Before open banking, connecting multiple accounts required manual exports and the use of spreadsheets. Yapily helps address this with consistent, enterprise-grade connectivity across more than 2,000 banks in 19 European markets.

How Yapily connects multiple business bank accounts

Yapily provides regulated open banking infrastructure for both Account Information Services (AIS) and Payment Initiation Services (PIS). Once users consent, Yapily facilitates secure authentication flows and data exchange between your platform and participating banks.

Here’s how the process works:

1. User consent: The business authenticates with each bank and grants permission to share account data.

2. Secure token exchange: Yapily receives an encrypted access token, not credentials.

3. Data retrieval: Yapily fetches balances, transactions, and account details directly from the bank’s API.

4. Multiple connections: Users repeat or extend the consent flow for each additional bank.

5. Ongoing sync: Yapily maintains data access with secure token refreshes, while users re-authenticate periodically (typically every 90 days in the UK, 180 days in the EEA).

This gives your platform continuous, consent-based access to financial data, without you having to manage separate integrations.

Best practices for managing multiple bank accounts

To ensure a smooth user experience and reliable data aggregation:

• Provide a central dashboard showing all connected accounts in one place.

• Standardise transaction formats using Yapily’s normalised data model for consistency.

• Manage consent renewal proactively so users maintain uninterrupted visibility.

• Support multi-authoriser flows for corporate and joint accounts.

• Use Yapily webhooks to refresh data automatically when new transactions are posted.

• Account for variations in data availability across banks and markets.

With Yapily handling the regulated connections, you can focus on building value — from spend analytics to cash-flow forecasting and treasury automation.
