Case Context & Problem: Manual Compliance Reporting at a Prague Logistics SME

The client is a growing small-to-medium enterprise (SME) in Prague, Czech Republic, operating in the logistics and supply chain sector. Their operations team, tasked with ensuring regulatory compliance, struggled with a monthly compliance reporting process that was highly manual, error-prone, and time-consuming.

Before automation, the team spent more than 20 hours every month collecting compliance data from multiple sources, primarily via email attachments and PDFs received from partners and internal systems. They then manually extracted, consolidated, and verified data in spreadsheets before submitting regulatory reports.

This manual process was fraught with pain points:

• Time Wastage: Over 20 hours (approx. 2.5 workdays) monthly lost to repetitive tasks.
• Errors & Inconsistencies: Manual data entry led to frequent mistakes and rework, delaying deadlines.
• Lack of Visibility: Real-time status tracking was impossible, causing last-minute surprises.
• Compliance Risks: Delays or inaccuracies risked penalties and damaged partner trust.

The impact extended beyond operational inefficiency; compliance teams worked under constant pressure, and management lacked timely dashboards to make data-driven decisions.

Our Approach: Process Mapping and Automation Proposal

At RestFlow, we began by conducting a thorough discovery phase, collaborating closely with the client’s operations and compliance teams. We mapped the entire manual workflow to identify bottlenecks and pain points.

Key insights included:

• Data was received irregularly via emails, often with multiple attachments and formats.
• The process required verifying report completeness before aggregation.
• Final reports were maintained in Google Sheets shared across teams.
• Notifications were sent manually via Slack or email, lacking traceability.

Given the complexity and integration needs, we proposed an automation architecture using n8n as the orchestration platform, due to its flexibility, open-source roots, and powerful native integrations. n8n was chosen over other tools because:

• Easy integration with Gmail, Google Sheets, Slack, and APIs.
• Ability to build complex workflows with decision nodes and error handling.
• Scalable self-hosting options available via RestFlow’s managed service.

This would enable automated data ingestion, validation, consolidation, and notification — all running with minimal human intervention.

The Solution: Architecture & Workflow

Global Automation Architecture Overview

The automated compliance reporting solution consists of these main components:

• Triggers: An n8n scheduler initiates the workflow daily to check incoming reports.
• Data Collection: Gmail integration retrieves new compliance report emails with attachments.
• Data Processing: Attachments are parsed (PDFs converted to structured data where possible), validated for completeness and accuracy.
• Data Consolidation: Validated data updates the master Google Sheets document shared with stakeholders.
• Notifications: Slack and email alerts are sent automatically to compliance leads summarizing report status or highlighting errors.
• Monitoring: RestFlow monitors workflow health, logs errors, and triggers retries or alerts as needed.

End-to-End Workflow Walkthrough

1. Scheduled Trigger: Each day at 9:00 AM CET, n8n triggers the workflow to check the Gmail inbox.

2. Retrieve Emails: The Gmail node searches for unread emails tagged "Compliance Report" with attachments.

3. Attachment Parsing: Attachment files are downloaded. PDFs undergo OCR and structured parsing when feasible; CSV or Excel sheets are parsed directly.

4. Data Validation: The data is checked for required fields, date ranges, and format correctness. Invalid or incomplete submissions are flagged.

5. Google Sheets Update: Valid data rows are appended or updated in the master compliance report sheet.

6. Notification Dispatch: Slack messages summarizing imported data counts and any errors are posted to the #compliance channel.

7. Status Dashboard: A Google Sheets dashboard reflects the latest import status with charts and KPIs.

This flow iterates daily, ensuring reports are collected and processed promptly, reducing manual work drastically.

Step-by-Step Node Breakdown 🚀

1. Scheduler Trigger Node

Purpose: Initiate workflow every day at a fixed time.
Configured to run at 9:00 AM CET using Cron expression.
Triggers subsequent Gmail data retrieval nodes.

2. Gmail: List & Read Emails Node 📧

Role: Fetch unread emails with "Compliance Report" label.
Filters: Label filter and attachment existence check.
Input: Gmail API query for unread, tagged emails.
Output: List of emails metadata including attachment links.

3. Attachment Downloader & Parser Node

Function: Downloads attachments.
For PDFs, integrates with OCR API to extract text and convert to JSON.
Supports Excel/CSV parsing via built-in nodes.
Key config: Mime-type filters, API keys for OCR securely stored in n8n credentials.

4. Data Validator Node ✅

Applies rules for required fields, date consistency, numeric ranges.
