NAB vs CommBank Business Banking: Compare the Operating Model

Comparing NAB and CommBank at bank level is broader than comparing NAB Connect with CommBiz. A business may care about transaction-account fees, branch/cash services, cards, lending, merchant services and relationship support as much as the online interface.

NabConn never asks for NAB Connect credentials

Use an official NAB-operated service for account authentication. Do not send NabConn your NAB Connect User ID, password, PIN, token code, one-time passcode, full card details or online-banking credentials.

Analysis

Online-Banking Architecture

NAB separates simpler Internet Banking from NAB Connect. CommBank similarly positions NetBank for simpler owner-managed business banking and CommBiz for multiple staff and payment-rule needs.

Analysis

Accounts and Transaction Behaviour

Compare monthly fees, electronic transaction charges, cash deposits and assisted banking based on actual monthly behaviour. Headline $0 accounts can still carry physical-service fees.

Analysis

Cards and Expense Control

Both banking groups offer business and corporate-card solutions. Evaluate employee limits, facility controls, expense integration and rewards separately from the current account.

Analysis

Switching Cost

A bank migration can affect direct debits, payroll, supplier instructions, integrations, cards and staff access. Include implementation cost in the comparison.
