Why the phone matters for payroll services firms

Payroll providers work on fixed deadlines, and a client who cannot reach them on payday is a client at risk. Calls about new hires, tax notices and pay corrections need to reach the right specialist quickly.

Calls payroll services firms commonly handle:

• A client calls to add a new employee before payroll runs.
• A client calls about an incorrect paycheck.
• A client calls about a state tax notice.
• The firm calls a client to confirm payroll hours.
• A prospect calls to ask about switching payroll providers.

Texting and after-hours calls

Firms text payroll cutoff reminders and approval requests.

Payday-eve calls benefit from an urgent flag so specialists can respond before the cutoff.

Avoid sending bank account or Social Security numbers by text.
