General

Small and Medium-sized Enterprises

Definition

Small and medium-sized enterprises by scale of business, as defined by the CMA, with a turnover less than £6.5m per annum. SMEs are a key beneficiary of Open Banking, gaining access to better financial products and services.

What is Small and Medium-sized Enterprises?

SME banking refers to banking and financial services designed for small and medium-sized enterprises. Definitions vary by region: in the UK the CMA uses turnover under £6.5m per annum; in the EU the standard is typically under 250 employees and turnover under €50m or balance sheet under €43m. SME banking covers business current accounts (BCAs), lending, payments, cash flow management, and accounting—all areas where open banking is having a major impact by giving SMEs access to tools and credit that were previously limited to larger firms.

SME Use Cases

SME Lending

Lenders use open banking to access real-time transaction data, verify income and cash flow, and make instant credit decisions—replacing slow, document-heavy processes. SMEs benefit from faster approvals and better rates.

Business Current Accounts

BCAs are in scope for open banking mandates in the UK and EU. SMEs can connect accounts to accounting software, treasury tools, and payment initiation for supplier payments and payroll.

Cash Flow & Accounting

Open banking feeds transaction data into bookkeeping and forecasting tools, reducing manual entry and giving SMEs real-time visibility into cash position and working capital.

Payment Initiation

SMEs can collect payments via Pay by Bank (lower fees than cards) and initiate bulk or recurring payments through PIS, improving settlement and reducing reliance on card networks.

Frequently Asked Questions

What is SME banking?

SME banking is the provision of banking and financial services to small and medium-sized enterprises—typically defined by turnover, headcount, or balance sheet. It includes business current accounts, lending, payments, cash management, and accounting services. Open banking is transforming SME banking by enabling instant data sharing and payment initiation via APIs, so SMEs get faster lending, automated reconciliation, and tools previously available only to larger corporates.

How does open banking help SMEs?

Open banking helps SMEs by giving lenders and service providers secure, real-time access to bank account data (with consent). That enables instant credit decisions, automated bookkeeping and reconciliation, cash flow forecasting, and Pay by Bank for lower-cost payments. In the UK and EU, business current accounts are included in open banking mandates, so SMEs can connect their accounts to a growing ecosystem of fintech tools.
