Case Context & Problem: Compliance Challenges for a Warsaw Firm

The client is a mid-sized compliance consultancy operating in Warsaw, Poland, serving enterprises across the EU. Their core business focuses on helping companies manage risk and comply with regulations including the emerging EU AI Act. Their compliance department, responsible for risk assessments and approvals, struggled under manual processes to ensure adequate human oversight and comprehensive traceability.

Before automation, their process involved:

• Manual intake of compliance cases via email and spreadsheets
• Unstructured human reviews with limited audit trails
• Escalation via phone calls and emails prone to miscommunication
• Significant delays causing backlog and SLA violations
• High potential for human errors and inconsistent documentation

This inefficiency created serious friction: their teams spent an average of 60 hours monthly managing manual oversight steps, with error rates reaching 15%. Audit preparedness was limited, risking regulatory penalties and damaging client trust.

Our Approach: Discovery and Automation Proposal

RestFlow’s team initiated the project with a thorough discovery phase. We collaborated closely with compliance officers, IT staff, and risk managers to map the existing workflows end-to-end. This exercise uncovered critical bottlenecks and identified key integration points.

Key systems used by the client included Gmail for correspondence, Google Sheets for data tracking, Slack for team communication, and a CRM system for client information. The manual processes lacked formalized states and documentation for human oversight checkpoints, escalating risks of non-compliance.

Given the complexity of approval gates, decision branching, and traceability needs, we recommended implementing automated human oversight and escalation workflows using the n8n automation platform orchestrated by RestFlow’s Automation-as-a-Service model. This platform was chosen for its flexibility, open-source nature, and ease of integration with the client’s existing tools.

The proposed architecture emphasized:

• Automated reception of compliance cases via webhooks triggered from form submissions and emails
• Structured workflows embedding human review gates and decision logging
• Automated escalation paths routed through Slack notifications and CRM task creation
• Complete audit trails stored in Google Sheets and cloud document repositories

By leveraging RestFlow’s expertise, the client aimed to shift from manual case handling to scalable, audit-ready automation compliant with the EU AI Act’s themes of risk management, transparency, human oversight, technical documentation, and traceability.

The Solution: Architecture & Workflow

The core architecture centers on RestFlow’s hosted and monitored n8n environment, acting as the orchestration hub. Incoming compliance cases trigger the workflow via:

• Webhook endpoints capturing form submissions or API calls from the client’s CRM
• Scheduled checks for new email alerts via Gmail integration

The automation then sequentially executes the following:

• Data validation and enrichment by cross-referencing CRM data and risk assessment criteria
• Decision branching enabling human review assignments based on case severity and type
• Notification dispatch to assigned compliance officers via Slack with approval buttons integrated
• Real-time logging of decisions and comments to Google Sheets for traceability
• Automated escalation if approvals are delayed beyond SLA thresholds, notifying supervisors and creating tasks in the CRM
• Generation and storage of technical documentation and compliance reports in cloud storage

The outputs provide a dashboard overview of case status and SLA adherence accessible to management.

End-to-End Workflow Walkthrough

1. Trigger: A new compliance case is submitted via a web form integrated with client CRM, creating a webhook trigger in n8n.

2. Data Validation: The workflow validates mandatory fields (e.g., client name, AI system category) against predefined compliance criteria.

3. Risk Categorization: Cases are enriched with risk levels by checking against embedded risk matrices stored in Google Sheets.

4. Human Review Assignment: Based on risk, the case is routed to the appropriate compliance officer with a Slack message containing decision options.

5. Logging & Decision Traceability: Responses are logged into audit spreadsheets with timestamps and reviewer comments.

6. Escalation Handling: If approvals do not happen within 48 hours, automated escalations notify supervisors via Slack and create CRM tasks.

7. Documentation Output: Upon completion, a compliance report is generated and stored in cloud storage, accessible for audits.

This workflow embodies automation aligned to the EU AI Act’s compliance pillars, ensuring processes are auditable, transparent, and scalable.

– Key fields: client_id, case_description, AI_risk_category.

– Configured with secure headers and token-based authentication for security.

2. Validation & Enrichment Node

– Uses n8n’s function nodes to verify required fields and enrich the case with data fetched from the CRM system via API.

– Conditional checks ensure completeness; missing data triggers notifications to compliance coordinators.

3. Risk Assessment & Branching Decision

– Integrates Google Sheets API to pull risk matrices.

– Applies logic conditions to route cases as Low, Medium, High risk.

– High-risk cases trigger additional review layers.

4. Slack Notification with Approval Buttons 🤖

– Sends an interactive Slack message to assigned reviewers describing the case.

– Includes buttons for Approve, Request More Info, or Escalate.

– Button clicks trigger webhook callbacks to the workflow for status update.

5. Logging Approvals & Comments

– Approval decisions and timestamps are logged into Google Sheets.

– Comments attached to each approval for traceability.

– Audit document URLs are generated and linked.

6. Escalation & SLA Monitoring ⏰

– A scheduler node checks pending cases.

– Cases exceeding response time trigger notifications to managers with case details.
