Decision framework
- If your bot just needs to answer FAQs: Tidio or Chatbase.
- If you're a SaaS with a help center: Intercom Fin.
- If you need to book appointments and integrate with field tools: Custom build.
- If you live in HubSpot already: Start with their Chatflows, upgrade if quality lags.
- If you have unique workflows (dispatching, quoting, intake): Custom build is cheaper at scale than stretching SaaS.
Why most SMBs end up custom
SaaS chatbot tools are great until you need them to do something the product manager never imagined. The moment you want to: pull customer history from your custom database, trigger a quote calculation, route by ZIP code to the right tech, or integrate with industry-specific software (ServiceTitan, AppFolio, Buildertrend, Practice Better) — SaaS tools either can't or charge enterprise prices.
A custom build using OpenAI or Anthropic APIs costs $1,500-$7,500 to deploy and runs $50-$500/mo in API costs. For SMBs with real workflows, that's the lowest total cost of ownership.
Frequently asked questions
Which chatbot is best for a Wisconsin contractor?
For most contractors, custom-built on OpenAI/Anthropic with calendar integration outperforms any SaaS option. SaaS tools weren't designed for trade-specific workflows like dispatch, urgency triage, and direct booking.
Can I switch chatbot platforms later?
Yes, but knowledge bases and conversation history rarely transfer cleanly. Pick a tool you can grow with for at least 12 months.
Do these all use ChatGPT under the hood?
Most use a mix of OpenAI (GPT-4/5), Anthropic (Claude), and Google (Gemini). Some platforms let you choose; others lock you in. Custom builds let you swap models as quality and cost change.
