M&T Bank Corp. has launched a new online payroll-processing service for small-business customers, aimed specifically at employers with fewer than 100 workers.

M&T Online Payroll, offered through a partnership with Sure Payroll, a subsidiary of Rochester-based Paychex, is now available in all communities served by the bank.

The service can be up and running for an employer in as few as seven business days after the small business enrolls through a secure website in a process that takes as little as 30 minutes, the bank said.

The service offers a centralized online site for payroll information and processing, direct deposit and check printing, flexible payment types, an online employee self-service site for pay stubs and year-end W-2 and 1099 statements, payroll reports and accounting software integration and legal compliance information.

“Being a small-business owner is complicated enough – from finding your next client to managing expenses,” said Janet M. Coletti, senior vice president of business banking.

“We’re now offering the simple option of managing payroll processing right through your bank.”
