What is an AI virtual agent? (And how small businesses can use them)

Running a small business means wearing a lot of hats. You’re managing calls, messages, appointments, marketing, and paperwork, so it’s no surprise that some customer communications can get missed. And every missed call or message could mean a missed opportunity.

But here’s the good news: you don’t have to do it all by yourself. An AI virtual agent can help manage conversations, handle scheduling, and answer customer questions around the clock. That means you look more professional, save time, and never have to worry about missing a lead.

In this guide, we'll walk through what a virtual AI agent is, what they're used for, and some of its benefits and challenges.

What is an AI virtual agent?

Put simply, an AI virtual agent (sometimes just called a virtual agent) is a digital helper that can chat with your customers in a natural, friendly way. It understands what people are asking and takes action, like answering questions, booking appointments, or transferring calls.

Unlike old-school chatbots that just spit out the same canned answers, a virtual AI agent actually holds real conversations. It listens, responds in a way that feels human, and can even remember to follow up.

For example, instead of just replying, “Our hours are 9 to 5,” an AI virtual agent might say, “We’re open until 5 PM today. Would you like to schedule an appointment this afternoon?”

That’s the difference: chatbots react, but a virtual agent AI helps.

How AI virtual agents work (a simple overview)

No need to get too technical here. Think of an AI virtual agent as a reliable team member who’s always available and never takes a break.

When someone calls, chats, or texts your business, your virtual agent listens, figures out what the person needs, and responds right away. Maybe it answers a question, takes a message, or books an appointment on your calendar.

Behind the scenes, it learns from your business info, instructions, and FAQs, so it sounds natural and professional. You control how it greets people, what it can do, and when it should bring in a real person.

Different types of AI virtual agents

AI virtual agents aren’t one-size-fits-all. Depending on how your business runs, you might want an agent that answers calls, chats online, responds to text/email, or automates repetitive tasks. Here are the main types you’ll see:

1. AI receptionists (AI voice agents)

If your business depends on phone calls, an AI receptionist is a great fit. These voice agents answer calls, greet customers, and handle routine things like booking appointments or sharing business hours. They can also forward important calls and send you a summary of what happened.

Example:

• Upfirst – an affordable AI virtual agent call center and answering service that helps small businesses handle calls, book appointments, qualify leads, route callers, and send follow-up texts 24/7.

2. Conversational chatbots (AI-powered chat agents)

Conversational chatbots are a step up from basic bots. These AI-powered virtual agents can hold real conversations on your website, over text, or on social media. They answer questions, qualify leads, and even help with orders all in a friendly, human-like way.

Examples:

• Intercom Fin – automates chat and helps support teams work faster.
• Drift – chats with website visitors and turns them into leads.
• Ada – answers FAQs via text/email, and sends tough questions to human support.

3. Task or workflow automation agents

These virtual agents work behind the scenes, automating repetitive tasks like sending follow-up emails, updating your CRM, or confirming appointments.

Examples:

• Conversica – follows up with leads to book meetings automatically.
• Moveworks – handles IT and HR requests for businesses.
• Zapier AI Agents – connects your apps and automates routine workflows.

4. Hybrid AI agents

Hybrid agents bring together voice, chat, and automation in one system. For example, Upfirst can answer calls, send one-way texts, and update your calendar all on its own.

So whether you need a phone answering service, chat support, or task automation, a virtual agent AI can be set up to communicate with customers the way you do business.

Key benefits for small businesses

Here’s why more small businesses are choosing AI virtual agents:

• Always available: Handle calls, texts, or messages 24/7 so you never miss out.
• Professional image: Every customer gets fast help and quick answers.
• Save time and money: No need to hire extra staff or pay overtime.
• Easy to scale: Whether you get 10 calls a day or 100, your AI agent can keep up.
• Consistent service: Customers always get clear, helpful answers.

Common use cases (with real examples)

AI-powered virtual agents can help almost any kind of business. Here are some popular ways they’re used, and the tools that make it happen:

1. Customer service and support

If you get lots of calls or messages, a virtual AI agent can greet customers, answer FAQs, and send requests to the right person.

Examples:

• Upfirst – AI receptionist that handles calls 24/7.
• Forethought – automates helpdesk tickets and responses.
• Ada – AI chat agent for instant support.

2. Appointment scheduling

Great for salons, repair shops, or medical offices, or anywhere customers need to book time. These agents confirm, reschedule, or cancel appointments automatically.

Examples:

• Upfirst – connects with Google Calendar, Outlook, and Clio to manage bookings (more calendar software to come).
• Drift AI – sets up sales demos and consultations.
• Conversica – books meetings with new leads.

3. Sales and lead qualification

Instead of manually following up with every new lead, let your AI virtual agent do it for you. It can qualify prospects and send the best ones to your sales team.

Examples:

• Upfirst - can ask callers your specific set of questions to qualify and intake new leads
• Intercom Fin – automates lead chats on your website.
• Drift – chats with visitors and routes hot leads to your team.
• Conversica – nurtures inbound leads without manual work.

4. Internal support and HR

AI virtual agents aren’t just for customers. Your internal team can use them to save time on things like password resets or policy questions.

Examples:

• Moveworks – AI support for IT and HR teams.
• Leena AI – automates HR questions and onboarding.

5. Service-based businesses (phone answering)

If you’re a plumber, electrician, or landscaper, you can’t always answer the phone. An AI virtual agent receptionist ensures you never miss a call, even after hours.

Examples:

• Upfirst – answers every call, routes important ones, and sends summaries to your team.
• Smith.ai – combines AI and live receptionists.
• Goodcall – an AI answering service that handles calls 24/7.

6. E-commerce and retail

AI agents can manage order questions, returns, and shipping updates automatically.

Examples:

• Zendesk AI Agent – answers support tickets and questions.
• Gladly – helps retail brands with personalized messaging.

Challenges and things to consider

Even the best AI-powered virtual agent needs a little setup:

• You’ll need to provide your business info, FAQs, and preferred tone.
• Make sure the language matches your brand and sounds natural.
• Keep an eye on data privacy and accuracy.

Once it’s up and running, your virtual AI agent can save you hours every week and help your business run more smoothly.

The future of AI virtual agents

AI virtual agents are getting smarter every day. The newest software can think, plan, and handle more complex tasks on their own.

For small businesses, this means you’ll have access to powerful automation tools that used to be available only to big companies.

All-in-one AI-powered virtual agent

Imagine a single virtual agent AI that could handle every customer touchpoint: phone calls, live chat, SMS, emails, and backend tasks all in one platform.

While no major provider fully offers this yet, the technology is quickly heading in that direction. Future all-in-one AI virtual agents could act as full digital team members:

• Greeting customers by name,
• Managing bookings and payments,
• Sending quotes or reminders, and
• Following up automatically across channels.

In other words, the all-in-one agent will combine the best parts of AI receptionists, chat agents, and automation tools, making true end-to-end communication possible.

This means a customer can speak with a receptionist over the phone and the conversation can continue via text or email, or start a conversation in webchat and continue the same conversation over phone.
