South Shore Bank

What South Shore Bank does

South Shore Bank is a mutual savings bank headquartered at 1530 Main Street, South Weymouth, Massachusetts, operating under mutual holding company Charlesbridge, MHC alongside affiliate Dedham Savings. Founded in 1833, the bank serves retail consumers, small and medium businesses, community associations, government entities, nonprofits, and wealth management clients across Massachusetts and the broader New England region. Its product portfolio spans deposit accounts (free checking, student checking, high-yield savings at 3.40% APY, money market, CDs, IRAs), consumer lending (mortgages, home equity, credit cards), business banking (free and commercial checking, treasury services, merchant services), business lending (lines of credit, term loans, commercial real estate, construction, SBA loans, Invest MA), and specialty divisions for property management, community associations, government, and nonprofit clients.

The bank operates a multi-channel distribution model combining Face2Face Virtual Teller branches with extended hours (7AM-7PM weekdays, 7AM-2PM Saturday), 24/7 ATMs, and digital banking via the Mobiliti mobile app and online platform. Core technology is provided by third-party vendors: NCR powers the Mobiliti mobile application, and Fiserv delivers the digital banking backend, bill payment processing, and fraud management. Other integrations include QuickBooks for SMB accounting, ZRent/ZDeposit/ZDeposit Speedbump for property management, Zelle for real-time payments, and Mastercard for debit card issuance. Biometric authentication (fingerprint and facial recognition) is offered as an optional mobile login method, with biometric data stored on-device only.

Revenue is generated through traditional banking mechanics: net interest income from the spread on loans and deposits, non-interest income from account fees and merchant services, and fee-based wealth management revenue. South Shore Bank is distinguished from most Massachusetts banks by Depositors Insurance Fund (DIF) membership, which insures deposits in full above FDIC limits, and by its comprehensive, vertically diversified product set within a community-bank footprint.
