AI chatbot for business — owned, not rented
Custom AI chatbots for small businesses. After-hours lead capture, 24/7 support, appointment booking, conversational intake. Pilots from $5,000, production builds from $8,000. Same architecture we use to ship Nexxus — the chatbot you can talk to on this site right now.
What does an AI chatbot for business cost — and what does it actually do?
A custom AI chatbot for business at Maxx Effect costs $5,000–$35,000 one-time. A Chatbot Starter ($5,000–$8,000) ships in 2-3 weeks with FAQ deflection and after-hours lead capture on one channel. A Production build ($8,000–$18,000) adds CRM and calendar integration across website, Messenger, and SMS. A conversational agent ($18,000–$35,000) handles multi-step workflows like booking + confirming + rescheduling, plus document understanding and voice. Every price is published.
The same workflow on Intercom Fin, Drift, or Ada runs $300–$2,000/month forever and you never own the chatbot. After 18 months of SaaS fees you have spent more than a custom build costs once, and you still have nothing if you cancel. For any SMB that wants to own the chatbot instead of rent it, custom wins long-term.
This page covers ai chatbot for small business, business chatbot, custom ai chatbot, and ai customer service chatbot — variants of the same intent.

Custom AI chatbot vs. SaaS chatbot — the 18-month break-even
Intercom Fin starts at $0.99 per resolution and tops out around $1.99. A small service business resolving 200 conversations per month is paying $200–$400/month. Drift Conversational Marketing starts at $2,500/month. Ada starts at $99/seat plus volume. Tidio Plus runs $749/month. Real numbers, public pricing.
A Chatbot Production build from Maxx Effect is $8,000–$18,000 one-time, $0–$500/month in optional hosting. Break-even against the cheapest SaaS option lands at month 18. Against Drift or Tidio Plus, break-even is month 6–9. After that, the custom build is pure savings forever — and you own it outright.

SaaS raises rates — your build does not
Four jobs an AI chatbot does reliably well
Honest answer: chatbots are not magic. They are very good at four specific jobs and overhyped on everything else. We build for the four.
After-hours lead capture (the highest-ROI workload)
60-80% of inbound web traffic for service businesses arrives outside business hours. A chatbot that asks three qualifying questions, scores intent, and hands off via email or SMS captures the leads that currently go to voicemail. Most chatbot builds we ship pay back on this single workload inside 90 days.
FAQ deflection trained on your real knowledge base
Not generic LLM answers — retrieval-augmented responses drawn from your actual FAQ pages, product docs, and past support tickets. Tier-one questions resolve without a human. Confidence drops below threshold, conversation escalates with full context. Target: 60-75% deflection rate on incoming questions, freeing your team for the 25-40% that need a human.
Appointment booking against your real calendar
Checks Google Calendar, Outlook, Calendly, or Acuity in real time. Proposes available slots, confirms the booking, sends reminders, handles reschedules. Works for dental practices, salons, contractors quoting jobs, law firms scheduling consultations. Pays for itself in recovered no-shows alone.
Conversational intake triage
Replaces the 10-minute phone screener with a 90-second conversational form. AI asks about the customer's situation, collects screening-level data, flags urgent matters, and prepares a one-page summary for the human team member who takes over. The pattern that drops new-patient processing from 12 minutes to under 3 (see /industries/dental).
This site has a chatbot. It is the one we ship.
Most chatbot vendors will not let you try the product they sell. Maxx Effect ships the same architecture to clients as we run on our own site — Nexxus, the AI assistant in the chat icon, was built on the same retrieval + agent stack we deploy in production engagements. Ask it about our pricing, our case studies, our process, when we are open. Same retrieval stack, same confidence threshold, same handoff to a human when it doesn't know.
When we send you a quote, you have already seen the product. No demo theater, no sales-engineer staged sandbox. The thing you talked to is the thing we will ship.

A chatbot that cannot reach your CRM, your calendar, or your practice management system is a fancy contact form. Real integration is where the ROI lives.
Channels
Website widget (50KB initial paint), Facebook Messenger, SMS via Twilio or MessageBird, voice via Twilio Voice or Vapi.ai. Channel-agnostic conversation memory so a lead can start on SMS and finish on email.
CRMs
HubSpot, Pipedrive, Salesforce, GoHighLevel, Zoho, Monday, Airtable. Bidirectional sync — chatbot writes new contacts, reads existing contact context to personalize the conversation.
Calendars + PMS
Google Calendar, Outlook, Calendly, Acuity for general scheduling. Open Dental, Eaglesoft, Dentrix, Curve for dental practices. Real-time availability check, confirmed bookings, automated reminders.
Model providers
Anthropic Claude (default), OpenAI GPT-5, Google Gemini, Mistral, open-source via Together or Replicate. Model choice is swappable — when a better model ships, we swap it in without rewriting your business logic.
