Why Sona is a better virtual receptionist for your accounting firm

Looking for a reliable answering service for your accounting business? Here are three reasons why Sona is the better choice:

1. Integrates directly in your business phone

OpenPhone is a collaborative business phone designed for small and growing businesses to communicate with their customers. You can make calls, send texts, and work with your team more efficiently using OpenPhone’s platform. 

Sona is directly integrated in OpenPhone. Team members with access to your workspace can view Sona’s call recordings, summaries, and transcripts, minutes after a call ends. 

On the other hand, traditional call answering services handle calls on their own platforms. You’re forced to use another app to track their conversations and your team has to spend additional time and effort mapping these calls to your contacts. 

2. More cost-effective

Save thousands of dollars a month with Sona. Many accounting firm answering services charge 4x-7x the cost of Sona. They have expensive plans based on a limited number of call minutes. And on top of that, additional per-minute charges apply if you exceed that limit. 

Sona is available for a flat fee for the first 50 calls it handles every month. After that, you’re charged a fixed fee for every call, not every minute. If a call runs for less than 15 seconds, like a spam call or a wrong number, you won’t get billed for it. Sona is designed to give you the most value from your virtual receptionist service. 

3. Consistent service

Imagine a virtual receptionist service that answers caller questions accurately, at any time of day. Or someone who asks the right intake questions when a new lead calls into your business, giving your team the context they need to assign the right tax professional to the job. Sona can execute these tasks in minutes.

Share general information about your firm with Sona, including business hours, important policies, and answers to common FAQs. Sona learns this information and gets up to speed quickly. Test it by hosting a couple of demo calls in our call flow builder and make adjustments if you need them. Provide custom instructions to Sona so it asks the follow-up questions that align with your business needs.

With live answering services, you never have full control over how their teams represent your business. You can spend weeks onboarding and training a third-party answering service, but there is always room for error. While live receptionist teams constantly face staff turnover, Sona always shows up for work and delivers the same level of service every time. 

Automated call answering for every CPA

Train Sona in seconds. Assign Sona to your calls in minutes.

Add Sona to your call flows easily

Don't lose out on potential new clients when you’re unavailable. Easily drag and drop Sona into your existing call flows, during and after business hours. Sona works alongside OpenPhone call routing features like ring order, phone menus, and call forwarding.

Train Sona to answer common questions

Save time for your team and let Sona answer your most common questions. Upload your key company policies and answers to FAQs so Sona can give the right information to your customers. 

Take detailed messages with follow-ups

Sona can ask follow-up questions based on specific keywords when it takes a message. For example, if a potential client is interested in scheduling a consultation for tax prep services, you can prompt Sona to ask if they need to file personal and business taxes, whether they require filing in multiple states, and more.

Get as many numbers as your firm needs with OpenPhone. Select from local US or Canadian phone numbers and North American toll-free numbers for your business. 

If your firm provides service for clients in multiple states, build trust with local clients when you get phone numbers with specific area codes. Or if you need an overarching number that appeals to a broader customer base, you can use a toll-free number.

OpenPhone plans include a unique phone number for each user who joins your workspace. Your team members can have individual numbers or you can share numbers and give access to everyone at your firm. Additional numbers cost just $5 per number per month.

Call handling made easy

Manage incoming calls easily, at any call volume, with OpenPhone. Set up flexible call flows during business hours and after hours with our call flow builder. Modify call flow steps in our drag-and-drop visual canvas. 

Choose how you want client calls to reach your team, either simultaneous incoming call notifications or in custom batches, with ring order.

Another admin task you can automate in OpenPhone: CRM logging.

What is an answering service?
down arrow

An answering service is a system that manages incoming calls on behalf of a business or an individual. It can operate in a company’s tech stack, like an AI voice agent, or it can be handled by an external provider, like a virtual assistant. Most answering services offer two overarching functions: they answer common questions or take messages from callers. 

What are the benefits of an accounting answering service?
down arrow

Here are three reasons why accounting businesses should use an answering service:

  1. Eliminate missed calls: An after-hours answering service helps accounting firms answer every call and capture every lead that comes their way (similar to dedicated sales AI tools). Answering service providers can set expectations for callers and inform them of next steps related to their reason for calling. 
  2. Answer common questions: If you don’t have an in-house receptionist, you might spend a lot of time answering basic questions about your firm’s business hours or your products and services. With an AI answering service, you can quickly answer your most common questions and provide a better customer experience in the process. 
  3. Take detailed messages: An AI receptionist takes detailed messages on behalf of your team. For example, if a prospective customer asks to schedule a consultation, Sona can collect details regarding their personal and business tax situation to have a more informed conversation.

Can an AI answering service boost client satisfaction?
down arrow

For prospective clients, an answering service can provide a professional first impression that gets them interested in working with your accounting firm. For existing clients, it’s a more convenient way to leave a message because it allows for a natural conversation instead of leaving an open-ended voicemail. 

What’s the difference between a call center and an answering service?
down arrow

A call center provides customer service operations and manages customer inquiries over the phone, usually on behalf of large-scale enterprises. Call centers can differ in terms of service quality; many companies choose to outsource these operations internationally due to the higher costs associated with US-based teams. They also require a lot of effort to set up because call center reps have to undergo extensive training and evaluation on company policies.

Phone answering services, on the other hand, aren’t designed to offer full-service customer support. These services can address basic customer questions, take messages, and relay communications to appropriate departments. They’re designed for businesses with lower call volumes or with occasional surges in calls, typically small businesses or fast-growing companies. 

What is the best accountant answering service?
down arrow

We’re biased, but in our opinion, Sona is the best accountant answering service. It’s available 24/7, trains on your company documents to provide accurate information, and takes detailed messages with the information that matters to your team. You can also monitor its performance and make adjustments to it at any time. Sona ensures you’ll never miss a client call again.
