The Problem
Why Accounting Firms Are Moving to an AI Answering Service
Client calls surge every year between January and the April filing deadline, then drop off for months at a time. A traditional answering service still bills you per minute or a flat monthly retainer no matter the season, and hiring seasonal staff means training people who leave once the rush ends. Retell answers on the first ring year round, and you only pay for the minutes you actually use, so a slow October costs a fraction of a busy March.

Per minute and per call, plus hold time and a flat monthly retainer that doesn't shrink in the off season
Callers hold for the next free operator, longer once tax season call volume climbs
Limited by how many operators are staffed, so the phones back up every tax season
Varies with whoever picks up, especially with seasonal temp hires
Usually English, more languages cost extra
Takes a message or transfers with little context
Write scripts, brief operators, wait for training, then retrain seasonal hires again next year

Capabilities
What Our Agent Does on a Call
Routes Every Client Call to The Right Person:
It works out why someone is calling, whether it's a filing question, a document request, or a new client inquiry, and routes them accordingly, with no phone menu to sit through.
Routing can follow your practice management system, so clients reach their assigned preparer instead of a general queue.
When a person is needed, the agent warm-transfers them along with the full conversation and client record.
Answers from Your Own Knowledge Base:
It stays in sync with your knowledge base, so callers hear current answers about hours, services and pricing, even during the busiest week of tax season.
It can look up a caller's record mid-call and tailor what it says.
It can pull from your CRM, practice management or billing tools over secure webhooks while the call is live.

FAQ
Common Questions
Can it handle the call volume spike during tax season?
Yes. Retell answers every call the same way whether it's a slow week in July or the rush before the April filing deadline. There's no queue and no need to staff up for a few months and then let people go.
Can it schedule appointments for tax filing consultations?
Yes. It can check your calendar and book, reschedule, or cancel filing consultations and other appointments during the call, then confirm the details with the client.
Can it answer questions about documents needed or filing deadlines?
Yes, if that information is in your knowledge base. It can walk clients through what documents to bring or upload and confirm filing deadlines, then transfer to your team for anything specific to their return.
How much does an accountant answering service from Retell cost?
Pricing is usage-based, starting at $0.07 per minute, with $10 in free credits to start. You pay for the minutes your firm actually uses, so a quiet month costs less than a busy one.
Does it handle calls in languages other than English?
Yes. It can handle calls in more than one language with the same answer quality as English.
How fast can we get this running before tax season starts?
Most firms start from a template, sync it with their knowledge base, and go live in days, not weeks.
What happens when a client needs to speak with a person?
The agent warm-transfers the call to your team along with the full transcript and client record, so nobody has to repeat themselves.
