This document summarizes open-source solutions for building a comprehensive automation ecosystem for small businesses and entrepreneurs. The goal is to create a complete integrated system without requiring the large budgets of commercial solutions.
Core Components
1. Process Automation (n8n)
- Role: Central automation tool, connecting various systems
- Advantages: Intuitive interface, minimal programming needed, pre-integrated with many services
- Deployment: Docker container or direct installation
- Applications: Process automation, data processing, system connections, creation of AI agents
2. Communication and Collaboration (Mattermost)
- Role: Centralized communication platform, user input/output interface
- Advantages: Similar to Slack but open-source, highly customizable
- Deployment: Docker container
- Applications: Communication hub, notification dashboard, interaction with AI agents
3. Customer Relationship and Marketing Management (Mautic)
- Role: Marketing automation, lead tracking
- Advantages: Multi-channel marketing automation, campaign management
- Deployment: Docker container
- Applications: Email marketing, landing pages, user behavior tracking
4. ERP and CRM (Odoo)
- Role: Comprehensive enterprise management system
- Advantages: Modular, expandable as needed, integrates multiple processes
- Deployment: Docker container
- Applications: Sales management, accounting, HR, projects, logistics, production
5. Business Process Management (Camunda)
- Role: Business process modeling and automation
- Advantages: BPMN standard compliant, visualization
- Deployment: Docker container
- Applications: End-to-end process design, monitoring, optimization
6. Identity Management (Keycloak)
- Role: Centralized authentication and authorization management (SSO)
- Advantages: One account for all systems, high security
- Deployment: Docker container
- Applications: Single sign-on, centralized account management
Integration Architecture
Overall Model

Main Integration Flows
- n8n as the Connection Hub:
- Receives events from all systems

Sample Automation Flows
1. Automated Sales Process
Receive potential customer (Mautic) | v Convert to opportunity (Odoo CRM via n8n) | v Initiate sales process (Camunda) | v Send notification to staff (Mattermost) | v Track and update progress (n8n + Odoo) | v Complete order and notify (Odoo -> n8n -> Mattermost)
2. Marketing Automation Process
Plan campaign (Camunda workflow) | v Create campaign in Mautic (n8n integration) | v Track campaign performance (Mautic) | v Analyze and report (n8n + AI agent) | v Notify results (Mattermost)
3. New Employee Onboarding Process
Create new employee (Odoo HR) | v Initiate onboarding process (Camunda) | v Automatically create system accounts (n8n + Keycloak) | v Send welcome email and information (Mautic) | v Notify team lead and assign mentor (Mattermost) | v Track and evaluate onboarding progress (n8n + Camunda)
Expansion and Advanced Features
1. Advanced AI Integration
In addition to using AI models through n8n, you can add:
- RAG (Retrieval Augmented Generation): Build agents capable of referencing internal data
- Automated Data Analysis: Extract insights from business data
- AI Assistant in Mattermost: Virtual assistant to help answer questions and support decisions
2. Data Analysis Solutions
Add analytics tools:
- Metabase: Visual dashboards without SQL
- NocoDB: Transform databases into visual spreadsheets
- Vector databases: Store and search unstructured data
3. Document Storage and Management
Add:
- Nextcloud: Secure document storage and management
- MinIO: Open-source object storage
- Joplin: Structured notes
Implementation Recommendations
For Small Businesses
- Start small, expand gradually:
- Deploy n8n and Mattermost first
- Add other systems when actual needs arise
- Focus on automating pain points:
- Identify current time-consuming processes
- Automate these first
- Human-machine collaboration:
- No need to automate 100% immediately
- Allow people and systems to work together
Technical Aspects
- Deploy Docker:
- Use docker-compose to manage all containers
- Focus on security and data backup
- Configuration management:
- Store configurations in git repository
- Use environment variables for sensitive information
- Monitoring:
- Deploy basic monitoring (Prometheus + Grafana)
- Set up alerts for important incidents
