Why the phone matters for tax preparation services in San Francisco, CA
Tax preparers do much of their year's business in a few months, and a missed call in March is often a lost return. Seasonal staff need to share one business number without giving out personal phones. That holds for tax preparation services in San Francisco, CA as much as anywhere.
Typical inbound and outbound calls for tax preparation services in San Francisco, CA:
- A returning client calls to book an appointment.
- A new client calls to ask what documents to bring.
- A client calls about a letter from the IRS.
Texting clients
Preparers text appointment confirmations and lists of documents to bring.
Team texting on Callata runs from your business number, so replies come from the practice or shop rather than someone's personal phone. It turns on after the one-time $49 carrier registration (10DLC) is approved.
