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 typical threshold is under 250 employees and turnover under €50m. SME banking covers business current accounts (BCAs), lending, payments, cash flow management, and accounting.

Open banking is transforming SME banking by giving lenders and service providers secure, real-time access to business account data with the customer's 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.
