How do I know which Business Online Banking system to use?

HomeStreet Business Online Banking accounts will use one of two online business banking platforms at Mechanics Bank beginning on Monday, March 23, 2026:

• Online Banking Plus
The majority of businesses will transition to Online Banking Plus.

• Commercial Center Online Banking
Business clients who streamline payables with online Automated Clearing House (ACH) transfers using the ACH Network and/or originate wire transfers online will be transitioned to the new Commercial Center Online and Mobile Banking platforms. If your business is being transitioned to the Commercial Center Online Banking platform, you will be notified in advance. Additional information, instructions, and training resources will be provided before March 20 - via your banker, through email, and through messaging on your current HomeStreet business online banking platform.
