The Math on Per-Resolution Pricing

Verdict

Best for: Enterprise teams with complex support needs and budget for per-resolution pricing.

Skip if: You're a small business or want predictable monthly costs. Per-resolution pricing scales linearly—every conversation costs money.

2. Zendesk AI — Best for Existing Zendesk Users

Zendesk AI integrates deeply with Zendesk's ticketing system. Their agentic AI can resolve issues end-to-end without manual setup or fixed flows.

Key Features

• Claims up to 80% automation for support issues

Verdict

Best for: Companies already using Zendesk who want AI-powered automation without switching platforms.

Skip if: You're starting fresh—Zendesk's per-agent pricing adds up quickly for small teams. A 5-person team pays $825+/month minimum.

3. Freshdesk Freddy — Best for Mid-Market Companies

Freshdesk Freddy offers three AI components: Freddy AI Agent (customer-facing), Freddy AI Copilot (agent assistance), and Freddy AI Insights (analytics).

Key Features

• Up to 80% query resolution across channels
• Pre-built integrations with Shopify, FedEx, Stripe, and more
• Live translation across 60+ languages
• No-code custom AI agent builder
• Real-time actions: process refunds, update orders, verify details

Pricing

• Growth: $18/agent/month (basic Freddy features)
• Pro: $59/agent/month (advanced Freddy)
• Enterprise: $95/agent/month (full Freddy suite)

Verdict

Best for: Mid-market companies wanting a balance of features and price, especially those in e-commerce.

Skip if: You need the simplest possible setup or have very low ticket volume—the per-agent pricing doesn't make sense for 1-2 person teams.

4. Tidio Lyro — Best for E-commerce & Small Businesses

Tidio Lyro combines live chat with AI-powered automation. It's particularly popular with Shopify and WooCommerce stores.

Key Features

• 70%+ resolution rate for routine queries

• Higher tiers: $79-149/month for 500-1,000 conversations

Note: Lyro is an add-on to Tidio's base plans ($29-349/month), so total cost is typically $68-150/month for small businesses.

Verdict

Best for: E-commerce businesses wanting AI + live chat in one platform with reasonable pricing.

Skip if: You only need AI (not live chat)—you're paying for features you won't use.

5. Chatbase — Best for Quick Setup & Developers

Chatbase lets you create a custom AI chatbot trained on your content in minutes. Popular with startups and developers who want fast deployment.

Key Features

• Train on websites, documents, or custom data

Pricing

• Free: 50 messages/month (chatbot deleted after 14 days of inactivity)
• Hobby: $40/month for 1,500 messages
• Standard: $150/month for 10,000 messages
• Pro: $500/month for 40,000 messages

Credit System Warning

Different AI models consume different credits. GPT-4 and Claude Opus use 20 credits per response, so 1,500 messages could mean only 75 actual GPT-4 responses.

Verdict

Best for: Developers and startups wanting quick setup with powerful AI models.

Skip if: You need human escalation—Chatbase doesn't offer it. When the AI can't answer, the conversation simply ends.

Modern AI chatbots achieve 50-80% resolution rates for routine queries. Intercom Fin averages 66% across customers. Well-configured chatbots with good knowledge bases can reach 70-80%. Rates below 50% usually indicate poor training data.

Which chatbot is best for small businesses?

For small businesses, look for flat monthly pricing (not per-resolution), human escalation capability, and easy setup. Tidio Lyro, Docuyond, and Chatbase offer affordable entry points. Avoid enterprise tools like Zendesk and Intercom unless you have high volume.

Can I switch chatbots later if I choose the wrong one?

Yes, but switching costs time and effort. You'll need to rebuild knowledge bases, retrain the AI, and update integrations. Before committing, test thoroughly during free trials and start with monthly billing to minimize lock-in.
