Unify Your Lead Flow & Never Miss a Job Again: The Open-Source Powerhouse

Are leads from your Google Business Profile, Local Services Ads, and website slipping through the cracks? For many home service businesses, a scattered lead intake process means slow responses, missed follow-ups, and frustrated customers choosing a faster competitor. This disorganization makes it impossible to track which marketing channels deliver valuable jobs, leading to wasted ad spend and lost revenue.


The Open-Source Powerhouse playbook provides a blueprint for building a unified, automated lead management system at a fraction of the cost of enterprise software. This stack uses a customizable Botpress chatbot to instantly engage leads 24/7, an open-source Cal.com scheduler to book jobs automatically, and a free Bitrix24 CRM to centralize every customer interaction. The entire system is connected by the powerful workflow automation tool, n8n.io, giving you complete control and visibility over your lead pipeline.

Expected Outcomes

  • Achieve near-instantaneous response times for all incoming digital leads, 24/7.
  • Eliminate missed follow-ups by centralizing every lead and interaction in a single CRM.
  • Increase conversion rates by allowing customers to self-schedule appointments immediately.
  • Gain clear visibility into which lead sources (Google, LSA, etc.) generate the most revenue.
  • Drastically reduce monthly software costs by leveraging powerful open-source and free-tier tools.
  • Build a fully customizable and scalable lead management system that you own and control.

Integration Logic

  • n8n.io

    The workflow begins when a user interacts with a Botpress chatbot and provides their contact information. Botpress sends this data to an n8n.io webhook. The n8n workflow is triggered, first creating a new Lead or Deal in Bitrix24 with the user's details. Next, it generates a unique, pre-filled scheduling link for the user via the Cal.com API. Finally, n8n sends this Cal.com booking link back to the Botpress chat, allowing the user to instantly schedule a meeting.
