Quick Summary

A B2B SaaS support inbox was buried in pre-sales questions that never reached the account team. GetLeadExpo built a chatbot on the SaaS site trained on product docs and pricing. It qualifies pre-sales enquiries, handles onboarding FAQs, and escalates real support tickets to the human team with full context. The account team now spends time on real deals, not repeat questions.

Client challenge

What the team was struggling with

  • The support inbox mixed pricing questions and real bug reports, slowing response times.

  • Prospects on pricing pages left because live chat was often offline.

  • Onboarding customers repeatedly asked the same setup questions.

  • No structured pipeline existed between chat, HubSpot, and the support tool.

Our solution

How GetLeadExpo solved it

We built a chatbot trained on product docs, pricing, and onboarding guides. It qualifies pre-sales leads into HubSpot, resolves Tier-1 onboarding questions, and creates support tickets with attached transcripts when a human is needed. Everything is orchestrated through n8n.

  4. 04

    Escalation rules

    Feedback loop

Lessons learned

What we'd tell the next team

  • Grounding on a real knowledge base is what keeps a SaaS chatbot trustworthy.

  • Escalation is a product decision, not just an engineering one — write the rules with the team.

  • A weekly feedback loop is what compounds chatbot quality over time.

  • Sales and support both need to trust the bot before it can run unattended.
